CLINUVEL’s SCENESSE® Gains EMA Approval for Unlimited Bi-Monthly Dosing

The European Medicines Agency has approved continuous bi-monthly dosing of CLINUVEL’s SCENESSE® for adult erythropoietic protoporphyria patients, removing previous annual dose limits and aligning Europe with US treatment standards.

  • EMA removes maximum annual dose limit for SCENESSE®
  • Year-round treatment now approved for adult EPP patients in Europe
  • Approval based on over 15 years of clinical trial and real-world data
  • European label harmonised with US FDA dosing regimen
  • CLINUVEL to continue safety monitoring via European EPP Disease Registry

Regulatory Shift in EPP Treatment

The European Medicines Agency (EMA) has taken a significant step in the management of erythropoietic protoporphyria (EPP) by approving a label amendment for CLINUVEL Pharmaceuticals’ SCENESSE® (afamelanotide). This change permits adult patients to receive the photoprotective implant every two months throughout the year, effectively removing the previous recommended cap of four implants annually.

This regulatory update harmonises the European treatment protocol with that of the United States, where year-round dosing has been common practice. The decision follows a comprehensive review by the EMA’s Committee for Medicinal Products for Human Use (CHMP), which evaluated extensive clinical trial data alongside real-world evidence accumulated over 15 years.

Data-Driven Confidence

The CHMP’s positive opinion reflects a robust benefit-risk profile for continuous SCENESSE® administration. The committee scrutinised data from pivotal Phase III studies and real-world patient outcomes, particularly focusing on safety and efficacy in patients receiving more than four implants per year. Their conclusion – no significant safety concerns arise from uninterrupted dosing, a critical endorsement for patients suffering from this debilitating condition.

CLINUVEL’s Chief Scientific Officer, Dr Dennis Wright, highlighted the importance of this milestone, noting that the expanded data pool now supports year-round treatment. He also pointed out the synergy between EPP and vitiligo programs, where SCENESSE® is administered even more frequently, further reinforcing the drug’s safety profile.

Addressing a Debilitating Condition

EPP is a rare genetic disorder causing extreme sensitivity to visible light due to the accumulation of phototoxic compounds in the body. Patients endure severe skin reactions that can incapacitate them for days or weeks, often leading to chronic skin damage and profound lifestyle restrictions. SCENESSE® remains the only approved systemic therapy that mitigates these phototoxic effects, enabling patients to regain a degree of normalcy.

With over 18,500 doses administered globally, the drug’s real-world impact is substantial. The EMA’s approval to remove dosing restrictions is expected to enhance patient access and treatment flexibility across Europe.

Ongoing Vigilance and Future Outlook

Despite this regulatory progress, CLINUVEL commits to rigorous post-approval monitoring through the European EPP Disease Registry, which holds nearly a decade’s worth of patient data. This ongoing surveillance will be crucial to ensuring long-term safety and effectiveness as year-round dosing becomes standard practice.

For investors and patients alike, this development signals a maturation of the SCENESSE® program and a potential expansion of its market footprint. It also underscores the evolving landscape of photomedicine, where data-driven regulatory decisions are paving the way for improved patient outcomes.

Bottom Line?

With EMA’s nod for year-round dosing, CLINUVEL sets the stage for broader SCENESSE® adoption and deeper patient impact.

Questions in the middle?

  • How will payers across Europe respond to the expanded dosing regimen in terms of reimbursement?
  • What impact will year-round treatment have on CLINUVEL’s revenue trajectory and market penetration?
  • Could the safety data from vitiligo treatments accelerate approvals for other indications?
