Zevra (ZVRA) Q1 2025: MyPlypha Captures One-Third of Diagnosed NPC Patients, Expanding Rare Disease Franchise

May 13, 2025 | By EarningsIQ Research

Zevra’s first full quarter post-MyPlypha launch demonstrates rapid patient enrollment, disciplined execution, and a reinforced cash position after a $148M PRV sale. Early traction in both U.S. and global rare disease markets, plus pipeline optionality, position Zevra for long-term value creation as payer coverage and patient identification efforts accelerate.

Summary

• MyPlypha Launch Penetration: One-third of diagnosed U.S. NPC patients now enrolled, validating commercial strategy.
• Cash Bolstered by PRV Sale: $148M non-dilutive capital enhances financial flexibility for pipeline and launches.
• Pipeline and Global Expansion: Accelerated EU submission plans and continued VEDS trial progress diversify future growth levers.

Performance Analysis

Zevra’s Q1 2025 results reflect a pivotal step into commercial-stage rare disease therapeutics, anchored by the launch of MyPlypha, a therapy for Niemann-Pick disease type C (NPC), and the repositioning of Olpruva for urea cycle disorders (UCDs). MyPlypha generated $17.1M in revenue, representing the bulk of the $20.4M total, with 13 new prescription enrollment forms in the quarter and 122 since launch, now covering roughly one-third of diagnosed NPC patients in the U.S. Olpruva, while early in its relaunch, contributed modestly but showed initial signs of traction in targeted adult and OTC-deficient segments.

Operating expenses decreased slightly YoY due to lower R&D spend as the KP-1077 Phase II trial wrapped, offset by a $9.6M YoY increase in SG&A tied to launch and commercialization. Net loss narrowed sharply to $3.1M from $16.6M a year ago, reflecting disciplined cost management and revenue ramp. Zevra’s cash position soared post-quarter with the $148.3M PRV sale, resulting in $217M in liquidity, supporting independence from capital markets and providing ample runway for clinical and commercial priorities.

• MyPlypha Launch Momentum: 122 enrollment forms, representing over one-third of diagnosed NPC patients, signal rapid uptake.
• Reimbursement Progress: 38% of covered lives achieved for MyPlypha; medical exception pathways supplement early payer denials.
• Olpruva Repositioning: Five new enrollments in targeted segments confirm early impact of refined commercial strategy.

With strong refill rates and durable patient retention mirroring EAP (Expanded Access Program) experience, MyPlypha’s commercial trajectory appears robust, though payer coverage and patient identification remain gating factors for further acceleration.

Executive Commentary

Strategic Positioning

1. MyPlypha: Cornerstone NPC Franchise

MyPlypha, first-in-class NPC therapy, has quickly established itself as Zevra’s commercial flagship. With one-third of diagnosed U.S. patients enrolled and broadening reach into both diagnosed and undiagnosed cohorts, Zevra’s patient identification, prescriber education, and payer engagement initiatives are driving tangible results. The product’s robust clinical data, including five to seven years of patient experience, underpins its differentiation and supports rapid payer adoption, despite initial prior authorization hurdles.

2. Olpruva: Targeted UCD Opportunity

Olpruva, UCD therapy, is being repositioned for adult and OTC-deficient populations, leveraging improved portability and palatability. All Q1 enrollments were within this refined segment, suggesting messaging is resonating, though the slow physician visit cadence in this population will temper near-term ramp. Zevra’s focus on patient-centric support and payer engagement is designed to gradually expand access and uptake.

3. Pipeline and Portfolio Optionality

Soliprolol, late-stage VEDS asset, continues to enroll patients in the Phase III DISCOVER trial, now at 32 subjects. Zevra is deploying genetic testing and targeted outreach to accelerate enrollment, critical for a rare disease with no approved therapies. The company also maintains optionality with KP-1077 (rare sleep disorders) and is actively curating its IP portfolio, recently outlicensing a preclinical prodrug and withdrawing the NDA for APIDAS to reduce costs.

4. Global Expansion and Regulatory Leverage

Zevra is preparing to file a European MAA for MyPlypha in the second half of 2025, aiming to address an estimated 1,100 NPC patients in a market with established reimbursement frameworks. Expansion of the global EAP (now 85 patients) may accelerate EU commercialization upon approval, leveraging real-world data and experience from the U.S. launch.

Key Considerations

This quarter marks Zevra’s transition to a commercial-stage rare disease company, with execution, resource allocation, and market access as central themes shaping its trajectory.

Key Considerations:

• Patient Identification Challenge: Only 300-350 of 900 U.S. NPC patients are diagnosed, making awareness and genetic testing critical for further expansion.
• Payer Dynamics: 38% of covered lives for MyPlypha is a strong start, but payer reviews and prior authorizations will determine the pace of revenue recognition.
• Cash Independence: $217M in liquidity post-PRV sale allows Zevra to execute launches and fund pipeline without near-term dilution risk.
• Pipeline Diversification: Progress in VEDS and strategic review of KP-1077 provide portfolio breadth and optionality for future value creation.
• Global Leverage: EU launch and global EAP expansion offer upside, but regulatory timelines and market access will dictate the trajectory.

Risks

Zevra faces the inherent risk of slow patient identification in ultra-rare diseases, payer and reimbursement barriers, and the long regulatory timelines for new geographies and pipeline assets. Commercial ramp for Olpruva remains uncertain given market fragmentation and low physician touchpoints. Pipeline execution, especially for VEDS, is dependent on successful patient recruitment and event-driven trial dynamics. Any delays or setbacks could impact growth visibility and investor confidence.

Forward Outlook

For Q2 2025, Zevra guided to:

• Continued expansion of MyPlypha enrollments, especially among diagnosed and undiagnosed patient cohorts
• Further progress in payer coverage and reimbursement for both MyPlypha and Olpruva

For full-year 2025, management did not provide specific revenue guidance but emphasized:

• Execution of MyPlypha and Olpruva launches as top commercial priorities
• Advancement of the VEDS Phase III trial and preparation for EU regulatory submission for MyPlypha

Management highlighted several factors that will influence results:

• Pace of new patient identification and conversion from enrollment to reimbursed therapy
• Expansion of payer coverage and successful navigation of prior authorization processes

Takeaways

Zevra’s Q1 performance confirms its commercial inflection and ability to execute in rare disease markets, with MyPlypha’s launch setting a new baseline for patient penetration and revenue visibility.

• Commercialization Traction: MyPlypha’s rapid uptake and payer engagement validate Zevra’s launch playbook and set the stage for broader adoption as awareness grows.
• Financial Flexibility: The PRV sale and disciplined cost structure give Zevra the resources to invest in both commercial and pipeline opportunities without reliance on external capital.
• Pipeline and Global Expansion: Success in VEDS and EU markets will be key swing factors for medium-term growth; investors should watch for enrollment cadence and regulatory milestones.

Conclusion

Zevra’s first quarter as a commercial-stage rare disease company demonstrates strong execution, rapid patient enrollment, and prudent capital management. With a robust cash position and continued progress in both the U.S. and global markets, Zevra is positioned for sustained growth and value creation as it builds out its rare disease franchise.

Industry Read-Through

Zevra’s early launch success with MyPlypha highlights the importance of targeted patient identification, payer education, and robust clinical differentiation in ultra-rare disease markets. The company’s disciplined approach to portfolio management and capital allocation sets a standard for emerging rare disease players, particularly those transitioning from development to commercialization. The ability to secure significant non-dilutive funding via PRV sales underscores the value of regulatory assets in funding growth without equity dilution. Other rare disease and specialty pharma firms should note the operational focus on payer engagement, patient support, and real-world evidence generation as critical levers for sustainable commercial ramp.
