DEVICE DESCRIPTION
Optilume BPH Catheter System
The Optilume BPH Catheter System is a combination drug/device minimally
invasive surgical therapy (MIST) comprised of an uncoated pre-dilation balloon
catheter and a separate drug coated balloon (DCB) catheter. The distal end of
each catheter has a semi-compliant, inflatable, double lobe balloon that is
used to dilate the prostate. The double-lobe DCB catheter is coated with a
proprietary coating containing the active pharmaceutical agent paclitaxel. The
drug coating covers the working length of the balloon body. Each Optilume BPH
Catheter is a single inflation lumen balloon catheter that terminates in an
atraumatic tip. The folded balloon has a 14.5Fr profile. The device is
inserted through the outer sheath of a rigid cystoscope and then visualized
procedurally in a side-by-side fashion with a cystoscope. The balloon has a
double lobe design with a neck separating the two sections. The balloon neck
is reinforced preventing diameter growth during the inflation process. The
double lobe design allows the balloon neck to seat in the bladder neck during
inflation and helps prevent migration of the balloon into the bladder. The
distal lobe of the balloon inflates in the bladder and aids in anchoring the
device, while the proximal lobe of the balloon is positioned in the prostatic
urethra to dilate the prostate and create an anterior commissurotomy. Both the
pre-dilation and the drug coated balloon catheters are identical, the only
difference being the DCB is coated with the drug paclitaxel as shown in Figure
2.
The Optilume BPH Catheter System is provided as a convenience kit, containing one pre-dilation balloon catheter, one DCB catheter, and the accessories needed to complete a procedure. Catalogue numbers for the different kit configurations are provided in Table 1.

Available Sizes and Nominal Paclitaxel Dose
The Optilume BPH Catheter System is available with one pre-dilation balloon
size (90Fr x 30mm) and four DCB sizes which are selected based on prostatic
urethral length (Table 2). The drug coating covers the working length of the
balloon component of the DCB and is evenly distributed across the balloon
surface at a nominal paclitaxel dose density of 2.4 μg/mm2. The drug coating
is released from the balloon and transferred to the prostatic urothelium
during balloon inflation.

INDICATIONS FOR USE
The Optilume BPH Catheter System is indicated for the treatment of obstructive urinary symptoms associated with Benign Prostatic Hyperplasia (BPH) in ????? 50 years of age.
CONTRAINDICATIONS
The Optilume BPH Catheter System is contraindicated for use in:
- Patients with known hypersensitivity to paclitaxel or structurally related compounds
- Patients with an active urinary tract infection
- Patients with an artificial urinary sphincter
- Patients with a penile prosthesis
WARNINGS
- The Optilume BPH Catheter System should be used only by physicians who are experienced and knowledgeable with the clinical and technical aspects of transurethral endoscopic treatment of BPH.
- Urotronic requires physician training on the Optilume BPH Catheter System prior to use. Please contact Urotronic for more information.
- The Optilume BPH Catheter is supplied for single use only. Do not reprocess or re- sterilize. Reprocessing and re-sterilizing could increase the risk of patient infection and risk of compromised device performance.
- Each balloon catheter is supplied sterile. Do not use the catheter if the sterile barrier is damaged or opened.
- The foil pouch and the outer surface of the inner Tyvek pouch are non-sterile. The contents of the inner Tyvek pouch are sterile. Use proper sterile technique to transfer the device from the inner Tyvek pouch to the sterile field.
- Do not use after the “Use By” date on the package label.
- Men should abstain from sex or use barrier contraception (wear a condom) for 30 days post treatment to avoid exposure of sexual partner to paclitaxel. Paclitaxel may still be present at low levels after 30 days.
- The Optilume BPH DCB contains paclitaxel, a known genotoxic aneugen capable of causing chromosomal abnormalities in sperm. Paclitaxel is present in semen for an extended duration after treatment with Optilume BPH. The total duration of time that paclitaxel remains in the semen post-procedure varies, but some men have had trace amounts detected up to 1 year after treatment. The risks associated with paclitaxel in semen are unknown. For this reason, men with partners of child-bearing potential should use highly effective contraceptive (to avoid fathering children) for at least 12 months post-procedure. Urologists should engage in a discussion with prospective patients regarding this risk and their individual family planning situation, with consideration of longer duration contraceptive use or other precautions based on a shared decision making process. Paclitaxel was detectable (i.e., equal to or greater than lower limit of quantitation of 0.1 ng/mL) in semen in 4/5 (80.0%), 5/7 (71.4%), 4/10 (40.0%), and 1/3 (33.3%) of evaluable subjects at 1 month, 3 months, 6 months, and 12 months post-treatment, respectively. Maximum paclitaxel concentrations in semen were 8.9, 7.5, 1.8, and 0.16 ng/mL at 1 month, 3 months, 6 months, and 12 months post-treatment, respectively, while group mean (SD) paclitaxel concentrations in semen at those same timepoints were 2.3 (3.7), 1.3 (2.8), 0.29 (0.53), and 0.09 (0.06) ng/mL. Of the three subjects who had evaluable data at 12 months post-treatment, one had detectable paclitaxel concentration in semen (0.16 ng/mL). The risks associated with these paclitaxel concentrations in semen are unknown. The effect of treatment with the Optilume BPH DCB on sperm and spermatogenesis is also unknown.
- Always inflate with a sterile liquid. Never inflate with air, carbon dioxide, or any other gas.
- The balloon catheters should not be inflated in excess of the rated burst pressure (RBP). Inflation to pressures above RBP may cause the balloon to rupture.
- During use, each balloon catheter of the Optilume BPH Catheter System should be manipulated under direct visualization via cystoscopy.
- If resistance is encountered at any time during insertion or removal, do not force passage. Resistance may cause damage to device or urethra. Ensure the balloon is fully deflated and under negative pressure during withdrawal.
- Monitor for signs of anaphylaxis or hypersensitivity to paclitaxel.
PRECAUTIONS
- Carefully inspect the product prior to use. Do not use the catheter if it is damaged or if the size, shape, or condition is unsuitable for the intended procedure.
- Do not immerse or wipe the Optilume BPH DCB with any fluid prior to use, as the integrity of the drug coating may be damaged or compromised. Replace the DCB if the balloon has come into contact with fluids prior to use.
- Use dry sterile gloves or dry gauze pads to handle the Optilume BPH DCB prior to use. Care should be taken to minimize contact with the drug coated portion of the device.
- Never inflate the Optilume BPH DCB outside the body or prior to reaching the prostatic urethra as it may disrupt the coating integrity.
- For proper drug delivery to the prostatic urethra, allow the drug coating on the balloon to hydrate while in the urethra for approximately 1 minute prior to inflation. Maintain inflation of the catheter for a minimum of 5 minutes. To optimize the anterior commissurotomy and drug delivery, longer inflation times > 5 minutes may be performed at the discretion of the operator.
- If the balloon catheter has a failure prior to or during inflation, replace the balloon catheter and inflate per procedure. If failure of the Optilume BPH DCB is after inflation to rated burst pressure (RBP), do not repeat/replace with a second DCB.
- Handle and dispose of the used device in accordance with accepted medical practice and applicable local regulations for biohazard waste.
DRUG INFORMATION
Mechanism of Action
The coating of the Optilume BPH DCB contains paclitaxel, an anti-mitotic
pharmaceutical agent that specifically binds to and stabilizes microtubules.
Paclitaxel has been reported to inhibit smooth muscle cell and fibroblast
proliferation and migration as well as secretion of extracellular matrix. The
combination of these effects may result in the inhibition of prostatic tissue
hyperplasia and re-fusion of the lateral lobes after achievement of the
anterior commissurotomy.
Drug Interactions
Formal drug interaction studies have not been conducted for the Optilume BPH
DCB. The respective instructions for use for all drugs used in conjunction
with the Optilume BPH DCB should be consulted for interactions with
paclitaxel.
Consideration should be given to the potential for systemic and local drug
interactions in the prostate in a patient who is taking a drug with known
interactions to paclitaxel or when deciding to initiate drug therapy in a
patient who has been treated with the Optilume BPH Catheter System.
The metabolism of paclitaxel is catalyzed by cytochrome P450 isoenzymes CYP2C8
and CYP3A4, and it is a substrate of P-glycoprotein. Potential drug
interactions may occur with any drug that affects these isoenzymes. In the
absence of formal drug interaction studies, caution should be exercised when
administering paclitaxel.
Carcinogenicity, Genotoxicity, and Reproductive Toxicology
The Optilume BPH DCB contains paclitaxel, a known genotoxic aneugen capable of
causing chromosomal abnormalities in sperm. Paclitaxel is present in semen for
an extended duration after treatment with Optilume BPH. The total duration of
time that paclitaxel remains in the semen post-procedure varies, but some men
have trace amounts detected up to 1 year after treatment. The risks associated
with paclitaxel in semen are unknown. For this reason, men with partners of
child-bearing potential should use highly effective contraceptive (to avoid
fathering children) for at least 12 months post-procedure. Urologists should
engage in a discussion with prospective patients regarding this risk and their
individual family planning situation, with consideration of longer duration
contraceptive use or other precautions based on a shared decision making
process. Paclitaxel was detectable (i.e., equal to or greater than lower limit
of quantitation of 0.1 ng/mL) in semen in 4/5 (80%), 5/7 (71.4%), 4/10
(40.0%), and 1/3 (33.3%) evaluable subjects at 1 month, 3 months, 6 months,
and 12 months post-treatment, respectively. Maximum paclitaxel concentrations
in semen were 8.9, 7.5, 1.8, and 0.16 ng/mL at 1 month, 3 months, 6 months,
and 12 months post-treatment, respectively, while group mean (SD) paclitaxel
concentrations in semen at those same timepoints were 2.3 (3.7), 1.3 (2.8),
0.29 (0.53), and 0.09 (0.06) ng/mL. Of the three subjects who had evaluable
data at 12 months post-treatment, one had detectable paclitaxel concentration
in semen (0.16 ng/mL). The risks associated with these paclitaxel
concentrations in semen are unknown. The effect of treatment with the Optilume
BPH DCB on sperm and spermatogenesis is also unknown.
Vascular Paclitaxel Coated Device Meta-Analysis
- A meta-analysis of randomized, controlled trials for the use of paclitaxel coated devices in treating patients with peripheral arterial disease (PAD) was published by Katsanos et. al in 2018.1 This analysis suggested the possibility of an increased risk of mortality resulting from the use of paclitaxel-coated vascular devices. This higher risk of death was observed at time points at least two years after treatment with the paclitaxel-containing devices. The presence and magnitude of the late mortality risk should be interpreted with caution because of multiple limitations in the available data, including wide confidence intervals due to a small sample size, pooling of studies of different paclitaxel-coated devices that were not intended to be combined, substantial amounts of missing study data, no clear evidence of a paclitaxel dose effect on mortality, and no identified pathophysiologic mechanism for the late deaths.
- In January 2021, Nordanstig and colleagues published interim results of a large, randomized national registry trial evaluating paclitaxel coated devices against uncoated control devices that showed no significant increase in mortality for paclitaxel coated devices through a median of 2.5 years follow-up.2 These results complement published outcomes from large national health insurance databases in the US and Germany showing no increase in mortality risk with the use of paclitaxel-coated devices. Longer term follow-up through 5 years is ongoing for these studies.
- Patients receiving the Optilume BPH Catheter System will be treated with a paclitaxel-coated balloon for a different condition (BPH) in a different part of the body (the prostate). Unlike the cardiovascular application, the drug is deposited on the urethra and not in the blood, although a small amount of drug can diffuse through the urethra into the blood. The mortality rate in the PINNACLE study evaluating the Optilume BPH Catheter System was 0.6 deaths per 100 patient follow-up years, which is no different than the expected rate of mortality for men in this age group.

POTENTIAL ADVERSE EFFECTS
Potential adverse effects after treatment with the Optilume BPH Catheter System are similar to standard cystoscopic procedures and mechanical dilation and include, but are not limited to fever, bleeding, pain, urinary tract infection, false route of the urethra, dysuria, difficult urination, frequency/urgency/irritative urinary symptoms, urinary retention and related symptoms, blood in urine (hematuria), urinary incontinence, urethrorrhagia, blood in semen (hematospermia), ejaculatory dysfunction, bladder perforation, urethral and/or bladder neck strictures, injury or perforation to the urethra, sphincter or prostatic capsule, and inflammation of genitourinary system (prostatitis, orchitis, balanitis). Although systemic effects from the paclitaxel coating are not anticipated, adverse effects observed during intravenous administration of paclitaxel for chemotherapy include, but are not limited to, allergic reaction, alopecia, anemia, gastrointestinal symptoms, hematological dyscrasia (including leucopenia, neutropenia, thrombocytopenia), hepatic enzyme changes, myalgia/arthralgia, myelosuppression, and peripheral neuropathy. Maximum systemic paclitaxel levels after treatment with the Optilume BPH DCB are more than 100 times lower than with IV administration of paclitaxel for chemotherapy.
STORAGE
The Optilume BPH Catheter System should be stored at room temperature between 15°C and 30°C (59°F and 86°F) in a dry location in its original packaging. The device should be used prior to the “Use By” date on the package label.
RECOMMENDED ITEMS
Prepare the following items using sterile technique:
- Lubricious surgical gel to aid with device insertion
- 60 mL inflation device with pressure gauge
- Three-way stopcock
- Tuohy-Borst adapter
- Rigid cystoscope (minimum sheath size 19.5F)
- Sterile saline
DIRECTIONS FOR USE
Perioperative Medications
- It is recommended that physicians follow guidelines for pre-procedure medications and preparation for a cystoscopic urethral procedure, including the administration of a pre-procedure antibiotic as appropriate. If a urinary tract infection (UTI) is present at the time of treatment, the patient must be treated until the infection is cleared before the Optilume BPH procedure can take place.
- The prostate is a highly vascularized organ and the Optilume BPH procedure, like other transurethral procedures for the treatment of BPH, may cause bleeding within the prostatic urethra. Peri-operative management of anticoagulant and antiplatelet medications is at the discretion of the treating physician and should balance the patient risk of thromboembolic events against the risk of hemorrhagic events.
Optilume BPH Size Selection
The selection of the appropriate kit for the Optilume BPH procedure is based
on the measured prostatic urethral length (PUL) of the patient. Use of
transrectal ultrasound (TRUS) to determine the PUL is recommended. The PUL
measurement should be taken in the mid-sagittal plane as a direct line from
the base of the bladder neck to the proximal edge of the external urethral
sphincter.
Note : If an intravesical prostatic protrusion (IPP) is present, the
measurement should be from the base of the bladder neck, NOT the tip of the
IPP.

Balloon Preparation
Before use, each balloon catheter in the Optilume BPH kit must be prepared for
use by evacuating air from the balloon catheter. The balloon lumen of the
catheter contains air and the air must be displaced to make certain that only
liquid fills the balloon while the catheter is in the urethra. Do not remove
the balloon protector sheath during catheter preparation.
- Open the inflation device package, remove the 3-way stopcock, and attach it to the Tuohy-Borst adapter.
- Connect the Tuohy-Borst valve to the proximal catheter shaft. Ensure that the catheter shaft does not interfere with the 3-way stopcock operation.
- Fill the inflation device half-way with sterile saline and attach it to the stopcock. Turn the stopcock so fluid can flow between the inflation device and the balloon catheter.
- With the inflation device pointing downwards, draw back plunger to full volume of syringe (this creates maximum negative pressure and allows air to evacuate above the fluid level) and hold until no air bubbles can be seen coming out of the saline in the syringe. Repeat as needed to purge the air from the catheter.
- With catheter preparation complete, disconnect the Tuohy-Borst valve from the catheter shaft.
- Fill the inflation device with 50cc normal saline and purge air from the line.
Pre-dilation
Pre-dilation of the prostatic urethra should be completed with the Optilume
BPH Pre-dilation Catheter to initiate an anterior commissurotomy prior to
treatment with the Optilume BPH DCB Catheter.
-
Prepare the Optilume BPH Pre-dilation Catheter for use per Section 11.3.
-
Assemble and advance the rigid cystoscope (minimum sheath size 19.5Fr) through the urethra and into the bladder. Remove the optics and bridge (if applicable) leaving an open pathway through the rigid sheath into the bladder.
-
Remove the balloon protector sheath from the Optilume BPH Pre-dilation Balloon.
-
Insert the balloon catheter through the rigid cystoscope sheath and into the bladder.
-
Slide the outer rigid cystoscope sheath out of the patient and over the balloon catheter shaft while maintaining the balloon catheter in position.
-
Reassemble the rigid cystoscope sheath with the bridge and optics.
Note : A smaller cystoscope sheath (e.g., 18F) may be used to visualize the balloon during placement. -
Attach the Tuohy-Borst adapter with inflation device to the proximal catheter shaft.
-
Insert the reassembled cystoscope transurethrally up to the external sphincter. The Optilume BPH Catheter is used side-by-side with a cystoscope.
-
Locate the external sphincter with the cystoscope and position the tip of the cystoscope so visualization of the external sphincter can be maintained throughout the procedure.
-
Adjust the position of the balloon by pushing/pulling the catheter shaft until the blue positioning marker is visible at the distal edge of the external urethral sphincter (Figure 4).
-
With the balloon properly positioned, inflate slowly while maintaining traction to seat the balloon at the bladder neck and prevent proximal migration into the bladder. During inflation, monitor the location of the blue positioning marker with the cystoscope. If the marker migrates proximally into the external sphincter (e.g., is no longer visible) or the treatment balloon has slipped into the bladder, deflate, and reposition the balloon as above and repeat the dilation process.
Warning: If migration of the balloon distally into the external sphincter (toward the user) is observed during inflation, immediately stop, and reposition. -
Continue slow inflation until the anterior prostatic commissure is separated. Achievement of an anterior commissurotomy is typically accompanied by a sudden drop in pressure on the inflation device pressure gauge as resistance from the tissue is overcome. Note: Once the balloon is inflated, check for migration into the bladder by pressing the catheter shaft gently toward the bladder. If the catheter shaft moves freely, the balloon has likely migrated into the bladder. If migration is observed, deflate the balloon, reposition the catheter as above, and repeat the dilation process. Do not repeat this procedure more than 3 times.
Warning: The balloon catheters should not be inflated to pressures above the rated burst pressure (RBP). Inflation in excess of RBP may cause the balloon to rupture. -
After complete dilation, deflate the balloon and visually confirm the anterior commissurotomy by advancing the cystoscope into the prostatic urethra.
Note: If difficulty is encountered visualizing commissurotomy, increase fluid
flow/pressure to improve visibility. -
Do not exceed 3 inflation cycles to rated burst pressure. If a commissurotomy is not achieved after 3 inflation cycles, deflate, and withdraw the Optilume BPH Pre-dilation Balloon per the steps below and proceed to dilation with the DCB.
-
After initiation of the commissurotomy is confirmed, remove the cystoscope.
-
Deflate the balloon by applying negative pressure with the inflation device to aspirate liquid from the balloon. Once the inflation device is filled with fluid, detach from the stopcock, purge fluid into a reservoir, reattach to the catheter, and repeat the aspiration process to ensure complete aspiration of liquid from the balloon.
Warning : If resistance is encountered at any time during insertion or removal, do not force a passage. Resistance may cause damage to the device or urethra. Ensure the balloon is fully deflated and under negative pressure during withdrawal. -
When the balloon is completely deflated, maintain a vacuum and gently pull on the catheter shaft to withdraw the catheter from the patient’s body.
Drug Coated Balloon Dilation
-
Prepare the Optilume BPH DCB for use per Section 11.3.
-
Advance the rigid cystoscope through the urethra and into the bladder. Remove the optics and bridge (if applicable) leaving an open pathway through the rigid sheath into the bladder.
-
Remove the balloon protector sheath from the Optilume BPH DCB.
-
Insert the Optilume BPH DCB through the rigid cystoscope and into the bladder.
-
Slide the outer rigid cystoscope sheath out of the patient and over the balloon catheter shaft while maintaining the balloon catheter in position.
-
Reassemble the rigid cystoscope sheath with the bridge and optics.
-
Attach the Tuohy-Borst adapter with the inflation device to the proximal catheter shaft of the Optilume BPH DCB.
-
Insert the reassembled cystoscope transurethrally up to the external sphincter. The Optilume BPH Catheter is used side-by-side with a rigid cystoscope.
-
Locate the external sphincter with the cystoscope and position the tip of the cystoscope so visualization of the external sphincter can be maintained through the procedure.
-
Adjust the position of the balloon by pushing/pulling the catheter shaft until the blue positioning marker is visible at the distal edge of the external urethral sphincter (Figure 4). This step should be completed in approximately 1 minute while the drug coating is hydrating, such that the balloon can be inflated after hydration is complete.
-
With the balloon properly positioned, inflate slowly while maintaining traction to seat the balloon at the bladder neck and prevent proximal migration into the bladder. During inflation, monitor the location of the blue positioning marker with the cystoscope. If the marker migrates proximally into the external urethral sphincter (e.g., is no longer visible) or the treatment balloon has slipped into the bladder, deflate and reposition the balloon as above and repeat the dilation process.
Warning : If migration of the balloon distally into the external sphincter (toward the user) is observed during inflation, immediately stop and reposition. -
With the balloon properly positioned, inflate the balloon using the inflation device. Maintain inflation for a minimum of 5 minutes to assure complete propagation of the anterior commissurotomy and appropriate drug delivery. To optimize the anterior commissurotomy and drug delivery, inflation times > 5 minutes may be utilized at the discretion of the operator.
Warning : The balloon catheters should not be inflated to pressures above the rated burst pressure (RBP). Inflation in excess of RBP may cause the balloon to rupture. -
Once the balloon is inflated, check for migration into the bladder by pressing the catheter shaft gently towards the bladder. If the catheter shaft moves freely, the balloon has likely migrated into the bladder. If migration is observed, deflate the balloon, reposition the catheter as above, and repeat the dilation process.
-
After completion of the commissurotomy, remove the cystoscope.
Note : Avoid visualizing the prostatic urethra with the cystoscope after dilation with the Optilume BPH DCB, as the irrigation fluid from the scope may disturb the drug coating delivered to the prostatic urethra. -
Deflate the balloon by applying negative pressure with the inflation device to aspirate liquid from the balloon. Once the inflation device is filled with fluid, detach from the stopcock, purge fluid into a reservoir, reattach to the catheter, and repeat the aspiration process to ensure complete aspiration of liquid from the balloon.
Warning : If resistance is encountered at any time during insertion or removal, do not force passage. Resistance may cause damage to device or urethra. Ensure the balloon is fully deflated and under negative pressure during withdrawal. -
When the balloon is completely deflated, maintain vacuum and gently pull on the catheter shaft to withdraw the catheter from the patient’s body.
Post Procedure Care
-
Upon completion of the dilation procedure, insert a Foley catheter and flush the bladder with sterile saline until the effluent returns clear.
Note : If difficulty is encountered during placement of the Foley catheter, it is recommended to place a guidewire and advance a council tip Foley over the guidewire to aid in placement. Rigid catheter guides are not recommended. -
It is recommended to place the Foley catheter on mild-to-moderate traction during the recovery period post-procedure to provide tamponade of any bleeding prostatic vessels.
Note : Use of traction for approximately 30 minutes post-procedure with at least a 30cc Foley balloon was found to reduce the rate of hematuria complications during clinical trials. -
The Foley catheter should remain in place for a minimum of 2 days to allow adequate healing and absorption of the drug into the prostatic adenoma.
SUMMARY OF CLINICAL STUDIES
Primary Study
- The PINNACLE study was a prospective, multicenter, double blind, 2:1 randomized controlled trial comparing the Optilume BPH Catheter System to a sham control procedure. In addition, a single arm of 15 non-randomized subjects were enrolled and treated with the Optilume BPH Catheter System to gather paclitaxel pharmacokinetic data. Subjects randomized to the Sham arm were allowed to cross over to receive the Optilume BPH Catheter System prior to the close of their 12-month visit window.
- Study enrollment began in January 2020 and was completed in September 2021. A total of 148 subjects were randomized in the study, 100 to the Optilume BPH arm and 48 to the Sham arm at 18 investigational sites. Treatment with the
- Optilume BPH Catheter System included use of the Optilume BPH Pre-dilation Balloon to initiate an anterior commissurotomy followed by dilation with the Optilume BPH DCB to further dilate and deliver drug to the prostatic urethra. The sham procedure utilized rigid cystoscopy followed by insertion of a sheathed (21F) Optilume BPH Pre-dilation Balloon that was modified to prevent inflation. Follow-up was completed at Foley removal, 14 days, 30 days, 3 months, 6 months, and 12 months and will be performed annually through 5 years for subjects treated with the Optilume BPH Catheter System.
Subject Accountability
- At the time of database lock, of 477 patients enrolled in the PMA clinical study, 148 were randomized, and 14 included in the PK sub-study. Subject disposition and visit compliance for the randomized cohort through 12 months is summarized in Table 4 and Figure 5.
- Withdrawals prior to the 12-month visit included 10 subjects randomized to the Optilume BPH arm (2 withdrew prior to receiving the study treatment, 2 lost to follow-up, 2 withdrew consent, 2 underwent a BPH surgical procedure, 2 initiated BPH medications) and 2 subjects randomized to the Sham arm (2 initiated BPH medications). Twenty subjects in the Sham arm crossed over to receive Optilume BPH prior to the 12-month visit.
- Primary efficacy and secondary endpoint analyses were performed using the intent-to-treat (ITT) data set which included all randomized subjects. Safety analyses were performed using the as-treated (AT) data set based on the treatment received. The AT data set excludes two subjects who were randomized to the Optilume BPH arm but did not receive the study treatment.

1Denominator represents the number of subjects eligible for a visit, while the
numerator represents the number of visits completed. Subjects that are
withdrawn from the study prior to the visit window opening are excluded from
the denominator.
For the primary endpoint intent-to-treat (ITT) analysis, subjects receiving
alternative BPH therapy were imputed as having no improvement, while endpoint
status for subjects with missing data were imputed via multiple imputation.

Efficacy Outcomes
Primary Efficacy Endpoint
The primary efficacy endpoint was a comparison of the change in International
Prostate Symptom Score (IPSS) at 3 months for the Control group and at 12
months for the Optilume BPH group. The endpoint incorporated a super-
superiority margin of 25% for the sham effect at 3 months. The analysis was
based on the ITT cohort which included 148 evaluable subjects (48 sham
subjects at 3 months and 100 Optilume BPH subjects at 12 months). Subjects
undergoing alternative therapy for ongoing/recurrent LUTS prior to the
scheduled timepoint were imputed as having no change from baseline. Missing
data were accounted for using multiple imputation. Incorporating the 25% super
superiority margin, the imputed difference between arms was +1.4 (p=0.178).
The improvement in IPSS for the Optilume BPH arm at 12 months did not reach
statistical significance with a 25% super-superiority margin when compared to
the improvement in the Sham arm at 3 months (Table 7).
Table 7. Primary Efficacy Endpoint – Improvement in IPSS (ITT, Multiple
Imputation)
Variable

Mean [95%CI]| [7.5, 12.5]| | [-1.6, 4.5]
P-value is based on a two-sample, independent t-test.
A post-hoc analysis was performed comparing the improvement in IPSS at 12 months for the Optilume BPH group to the improvement of a historical sham control at 3 months based on a systematic review of the literature of sham endoscopic procedures in randomized trials for BPH. A total of 8 studies were included in the analysis and used to generate the pooled sham effect (weighted average) across studies.3-10 Four studies reported a paired change in IPSS from baseline to 3 months. 5,6,8,9 Comparing the improvement in IPSS against the pooled sham effect from the literature as a performance goal shows a benefit for Optilume BPH both with and without a 25% super-superiority margin (Table 8). A similar outcome is seen when utilizing only those publications reporting paired change scores.

Optilume BPH mean improvement utilizing ‘Retreatments Imputed’ methodology,
where those receiving alternative treatment are imputed as having no
improvement.
Secondary Endpoints
Hypotheses for the secondary endpoints were not formally tested because the
study failed to meet its primary effectiveness endpoint and supplemented by
post-hoc analysis.
Secondary Endpoint 1 – Average IPSS Improvement in Test Arm at 12 Months
The average percent improvement in IPSS from baseline to 12 months was
compared against a performance goal of 30%. Subjects undergoing alternative
therapy for ongoing/recurrent LUTS prior to the scheduled timepoint were
considered as having no improvement, while subjects considered missing at
random were imputed utilizing multiple imputation as per the primary efficacy
endpoint analysis. The average improvement from baseline to 12 months for the
Optilume BPH arm was 49%, which is greater than the target 30% threshold.

Secondary Endpoint 2 – Responder Rate at 3 Months (Optilume BPH) vs 3
Months (Sham)
The rate of responders at 3 months in the Optilume BPH arm was compared to the
rate of responders at 3 months in the Sham arm. A responder is defined as a
subject who has an IPSS alternative therapy for ongoing/recurrent LUTS prior
to the scheduled timepoint were considered as having no improvement in the
analysis. The responder rate at 3 months was numerically higher in the
Optilume BPH arm compared to the Sham arm.

N=4 patients excluded from analysis due to missing values.
Secondary Endpoint 3 – Responder Rate at 12 Months (Optilume BPH) vs 3 Months
(Sham)
The rate of responders at 12 months in the Optilume BPH arm was compared to
the rate of responders at 3 months in the Sham arm. A responder is defined as
a subject who has an IPSS alternative therapy for ongoing/recurrent LUTS
prior to the scheduled timepoint were considered as having no improvement in
the analysis. The responder rate at 12 months in the Optilume BPH arm was
higher than the responder rate at 3 months in the Sham arm (76.6% vs 52.1%).

Secondary Endpoint 4 – Change in Qmax
The change in Qmax at 12 months in the Optilume BPH arm was compared to the
change in Qmax at 3 months in the Sham arm. Subjects opting to receive
alternative therapy or withdrawing due to perceived lack of effectiveness were
considered as having no improvement. The Optilume BPH arm showed a higher
increase in Qmax at 12 months when compared to the increase in Qmax seen in
the Sham arm at 3 months.

Ancillary Endpoints
Analysis of the following ancillary endpoints demonstrated improvement through
12 months follow-up.
Ancillary Endpoint 1 – Additional Responder Analyses with a Responder Defined
as IPSS Improvement of 35%, 40% and 50%
The change in IPSS for both arms is presented using a Retreatments Imputed
analysis which carries forward baseline values for subjects considered
treatment failures (Table 9). The proportion of subjects with at least 35%,
40% and 50% improvement in IPSS is higher in the Optilume BPH arm compared to
the Sham arm at all timepoints evaluated (Table 10).

Ancillary Endpoint 7 – Procedure Parameters
Procedures were performed in an ambulatory surgical center (81.5%) or office-
based location (18.5%). The average (SD) time for the Optilume BPH procedure
from cystoscope insertion to removal of the treatment device was 26.0 (8.2)
minutes (n=98).
Ancillary Endpoint 9 – Proportion of Subjects Experiencing a Return to
‘Normal’ Symptom Severity (IPSS<8)
Approximately one-third of subjects (30.9%, 29/94) treated with the Optilume
BPH Catheter System returned to ‘normal’ symptom levels by 12 months post-
treatment compared to 14.6% (7/48) in the Control group.

Safety Outcomes
The primary safety endpoint of the PINNACLE study was defined as the proportion of subjects experiencing a composite of major device-related serious complications through 12 months post-procedure: rectal or gastrointestinal fistula, fistula between the rectum and urethra, new onset severe urinary retention lasting >14 consecutive days post-healing, unresolved de novo stress urinary incontinence by 90 days, bleeding requiring transfusion, and urethra or prostatic capsule rupture requiring surgical intervention. No subjects experienced an event qualifying for the pre-defined composite of serious device-related complications through 12 months as adjudicated by the Clinical Events Committee (CEC).

Treatment-related serious adverse events were reported in 6 (6.1%) subjects,
most commonly post-procedure hematuria (4 events) which resolved without
sequelae. The most frequently reported treatment-related adverse events
included hematuria (39.8%), urinary tract infection (11.2%), dysuria (8.2%),
and mild stress urinary incontinence (7.1%). Treatment-related adverse events
were mostly mild or moderate in severity (138/143, 97%). There were no life
threatening (Grade 4) or fatal (Grade 5) events related to either the study
device or procedure.
A total of 41 hematuria and post-procedural hematuria events occurred in 39
subjects (39.8%) with most events being mild or moderate in severity (37/41,
90.2%) with a median time to resolution of 34 days. The rate and severity of
hematuria events was decreased after implementation of post-operative care
guidelines as described in section 11.6.

Pharmacokinetic Profile
A sub-study including 15 non-randomized subjects was conducted to determine
the pharmacokinetic profile of paclitaxel in blood (plasma), urine, and semen
after treatment with the Optilume BPH DCB. Determination of plasma paclitaxel
concentration was evaluated immediately after completion of the procedure, at
1, 3, and 5 hours, and at Foley removal, 30 days, 3 months, and 6 months post-
procedure. Urine paclitaxel concentration was evaluated immediately post-
procedure, at Foley removal, and at 30 days, 3 months, and 6 months. Semen
paclitaxel concentration was evaluated at 30 days, 3 months, and 6 months
post-procedure.
A summary of pharmacokinetic parameters, including maximum concentration
(Cmax) and time to maximum concentration (Tmax) for plasma is in Table 21.
Paclitaxel concentration over time in urine and semen can be found in Table 22
and Table 23, respectively. On average, paclitaxel concentration in plasma
fell below the limit of quantitation of the method (0.10 ng/mL or 0.1 part per
billion) by the time of Foley removal, while average paclitaxel concentration
in urine approached the limit of quantitation by 6 months. Analysis of
paclitaxel concentration in semen showed low but persistent levels of
paclitaxel in semen through 6 months post-treatment. Of the three subjects who
had evaluable data at 12 months post-treatment, one had detectable paclitaxel
concentration in semen (0.16 ng/mL).

Supplemental Clinical Study
EVEREST-I was a prospective, non-randomized, open label, multicenter study to
evaluate the safety and efficacy of the Optilume BPH Catheter system for the
treatment of LUTS secondary peak urinary flow rate 5-15 mL/sec, post-80
grams, and prostatic urethral length 35-55 mm. Key exclusions included prior
minimally invasive or surgical intervention of the prostate, intravesical
prostatic protrusion >1 cm, and confounding urologic conditions (e.g.,
neurogenic bladder, stricture). Subjects had to undergo drug washouts prior to
treatment including alpha blockers for 3 weeks and 5-alpha reductase
inhibitors for 6 months. Subjects were followed at Foley removal, 2 weeks, 30
days, 3 months, 6 months, and 1-year post-treatment, and annually thereafter
through 3 years. Follow-up is planned through 5 years.
A total of 80 subjects were enrolled and treated at 6 clinical sites in Panama
and the Dominican Republic. Subjects were 65 years old on average with a
prostate volume of 35.9 grams. The primary efficacy endpoint was the responder
rate at 3 months based on an improvement in were considered responders with a
lower 90% confidence limit of 72.6% which met the performance goal of 50%.

The primary safety endpoint was a composite of device and procedure related serious complications at 3 months including new onset severe urinary retention lasting >14 consecutive days post-healing, unresolved new onset stress urinary incontinence by 90 days, and bleeding requiring transfusion. Two subjects experienced stress urinary incontinence meeting the endpoint criteria for a rate of 2.5%. Both subjects were treated with a larger diameter balloon that is no longer included in the matrix of available device sizes.
