Keenova Marks 100K Peyronie’s Disease Patients–a Major Milestone for an Often-Stigmatized Men’s Health Condition

100,000 men have been prescribed XIAFLEX^® (collagenase clostridium histolyticum) to treat their Peyronie’s disease¹*
Diagnosis rates for the condition remain low because men with PD may be too uncomfortable to speak up and get help
In 2026, Keenova will focus on building awareness to help improve diagnosis rates with new and enhanced initiatives, including evolved marketing campaigns and more patient voices

DUBLIN, Jan. 21, 2026 /PRNewswire/ — Keenova Therapeutics plc announced today that it reached a milestone: 100,000 patients with Peyronie’s disease (PD) have been prescribed XIAFLEX^®(collagenase clostridium histolyticum).¹*

XIAFLEX is the only FDA-approved nonsurgical treatment for adult men with PD who have a “plaque” that can be felt and a curve in their penis greater than 30 degrees when treatment is started.² Do not receive XIAFLEX if you have had an allergic reaction to collagenase clostridium histolyticum or any of the ingredients in XIAFLEX, or to any other collagenase product.

Why It Matters
XIAFLEX launched in 2013 as the first and only FDA-approved nonsurgical treatment for PD. The condition is thought to be more prevalent than reported.² Diagnosis rates remain low because men with PD may be too uncomfortable to speak up and get help.³

“This milestone is a testament to the strength of those patients who have overcome their physical and emotional discomfort to seek help for PD,” said Dan Plunkett, Executive Director of Marketing at Keenova.

“The achievement also reflects the dedication and collaboration of teams across the patient journey—from researchers who developed the treatment to the urology specialists who care for patients and administer XIAFLEX,” Plunkett continued. “At Keenova, we are proud of our continued commitment to men’s health and to supporting men with Peyronie’s disease.”

Building Awareness and Impact in 2026
Keenova will continue its awareness efforts in 2026 and empower men to speak with a urology specialist and explore whether XIAFLEX is right for them.

Marketing campaigns to reach men and partners: Keenova’s campaigns—including Bent Carrot and Prime Time—are running on digital and social channels and on streaming and video platforms such as Prime Video, CBS, HBO Max, Hulu, and Peacock. This year, Keenova will evolve its messaging to engage the partners of those with PD to help spark conversations about the condition.
Patient voices on social media: Social media sites like Meta and Reddit have proven to be powerful drivers for educating adult men with PD and empowering them to act. Keenova will expand its efforts on social media and amplify patient experiences and stories on those platforms.
Mixed reality tool for providers to enhance technique: Launched in 2025, the Spatial Computing Injection Simulator allows urology specialists to interact simultaneously with both physical and digital objects—blending a physical penile model and digital content via an Apple Vision Pro app—to help refine their injection technique. Keenova will expand use and access to the simulator to help healthcare providers build clinical confidence.

About Peyronie’s Disease
Peyronie’s disease is a condition in which a buildup of fibrous scar tissue causes a curvature deformity of the penis. This curvature can be bothersome during arousal and intimacy.⁴ Diagnosis rates remain low because men with PD may be too uncomfortable to speak up and get help.³

* As of January 2026, 100,020 men have been prescribed XIAFLEX for PD. Calculations and estimations based on transactions for XIAFLEX for PD from January 1, 2014 to January 13, 2026.¹

IMPORTANT SAFETY INFORMATION

Do not receive XIAFLEX if:

the Peyronie’s plaque to be treated involves the “tube” that your urine passes through (urethra).
you are allergic to collagenase clostridium histolyticum or any of the ingredients in XIAFLEX, or to any other collagenase product. See the end of the Medication Guide for a complete list of ingredients in XIAFLEX.

XIAFLEX can cause serious side effects, including:

1. Penile fracture (corporal rupture) or other serious injury to the penis. Receiving an injection of XIAFLEX may cause damage to the tubes in your penis called the corpora. After treatment with XIAFLEX, one of these tubes may break during an erection. This is called a corporal rupture or penile fracture. This could require surgery to fix the damaged area. Damage to your penis might not get better after a corporal rupture.

- After treatment with XIAFLEX, blood vessels in your penis may also break, causing blood to collect under the skin (hematoma). This could require a procedure to drain the blood from under the skin. If a hematoma appears, skin and soft tissue necrosis (death of skin cells) may develop in that area, which could require surgery.

Symptoms of corporal rupture or other serious injury to your penis may include:

a popping sound or sensation in an erect penis
sudden loss of the ability to maintain an erection
pain in your penis
purple bruising and swelling of your penis
difficulty urinating or blood in the urine

Call your healthcare provider right away if you have any of the symptoms of corporal rupture or serious injury to the penis listed above.

Do not have sex or any other sexual activity between the first and second injections of a treatment cycle.

Do not have sex or have any other sexual activity for at least 4 weeks after the second injection of a treatment cycle with XIAFLEX and after any pain and swelling has gone away.

XIAFLEX for the treatment of Peyronie’s disease is only available through a restricted program called the XIAFLEX Risk Evaluation and Mitigation Strategy (REMS) Program.

2. Hypersensitivity reactions, including anaphylaxis. Severe allergic reactions can happen in people who receive XIAFLEX, because it contains foreign proteins.

Call your healthcare provider right away if you have any of these symptoms of an allergic reaction after an injection of XIAFLEX:

• hives

• swollen face

• breathing trouble

• chest pain

• low blood pressure

• dizziness or fainting

3. Back pain reactions. After receiving an injection of XIAFLEX for Peyronie’s disease, you may suddenly feel back pain, including severe lower back pain moving to your legs, feet, chest and arms. The back pain may also include spasms and make it hard to walk. These symptoms usually go away in 15 minutes or less, but may last longer.

Tell your healthcare provider right away if you have sudden back pain, chest pain, or hard time walking after an injection.

4. Fainting. Fainting (passing out) or near fainting can happen in men who receive XIAFLEX, especially if they have severe penile pain.

If you have dizziness or feel faint after receiving XIAFLEX, lie down until the symptoms go away.

Before receiving XIAFLEX, tell your healthcare provider if you have had an allergic reaction to a previous XIAFLEX injection, have a bleeding problem, received XIAFLEX for another condition, or any other medical conditions. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Using XIAFLEX with certain other medicines can cause serious side effects. Especially tell your healthcare provider if you take medicines to thin your blood (anticoagulants). If you are told to stop taking a blood thinner before your XIAFLEX injection, your healthcare provider should tell you when to restart the blood thinner. Ask your healthcare provider or pharmacist for a list of these medicines, if you are not sure.

What should I avoid while receiving XIAFLEX?

Avoid situations that may cause you to strain your stomach (abdominal) muscles, such as straining during bowel movements.

Do not use a vacuum erection device during your treatment with XIAFLEX.

XIAFLEX can cause serious side effects, including increased chance of bleeding. Bleeding or bruising at the injection site can happen in people who receive XIAFLEX. Talk to your healthcare provider if you have a problem with your blood clotting. XIAFLEX may not be right for you.

The most common side effects with XIAFLEX for the treatment of Peyronie’s disease include:

a small collection of blood under the skin at the injection site (hematoma)
swelling at the injection site or along your penis
pain or tenderness at the injection site, along your penis and above your penis
penis bruising
itching of your penis or scrotum (genitals)
painful erection
erection problems (erectile dysfunction)
changes in the color of the skin of your penis
blisters at the injection site
pain with sex
a lump at the injection site (nodule)

Tell your healthcare provider if you have any side effect that bothers you or does not go away.

These are not all of the possible side effects with XIAFLEX. For more information, ask your healthcare provider or pharmacist. You may report side effects to FDA at 1-800-FDA-1088.
