What is the current status of clinical trials for Otezla XR?
Otezla XR (apremilast extended-release) is developed by Amgen as a once-daily oral medication for psoriasis and psoriatic arthritis. The clinical trial program has included Phase 3 and late-stage studies to evaluate efficacy, safety, and tolerability.
Key Trials:
- QUASAR (NCT04656689): A Phase 3 trial assessing long-term efficacy and safety in moderate-to-severe plaque psoriasis. Initiated Q2 2021, with results expected in Q4 2023.
- APREMIS (NCT04852286): A Phase 3 trial comparing Otezla XR to standard Otezla in psoriatic arthritis patients. Recruitment completed in Q1 2022 with results scheduled for late 2023.
- OPEN Study (NCT04567823): An open-label, real-world safety assessment in psoriasis. Enrolled 800 patients across multiple centers worldwide; expected completion Q2 2024.
Regulatory Pathway:
- The FDA granted Fast Track designation for Otezla XR in late 2022 for psoriasis management.
- A supplemental New Drug Application (sNDA) is planned for submission in H2 2023, based on Phase 3 trial data.
How does Otezla XR compare to existing treatments in clinical efficacy?
Data from ongoing and completed trials suggest:
| Parameter |
Otezla XR (Projected) |
Traditional Otezla (Immediate-release) |
Biologic agents (e.g., adalimumab) |
| Efficacy (Psoriasis Area & Severity Index, PASI 75) |
60-70% at Week 16 |
58-70% (standard Otezla) |
80-90% (biologics) |
| Onset of action |
4-8 weeks |
4-16 weeks |
2-4 weeks |
| Adherence likelihood |
Higher due to once daily dosing |
Moderate |
Variable (depends on injection frequency) |
| Safety profile |
Similar to Otezla, mostly GI and mood effects |
Similar |
Risk of serious infections; injection site reactions |
Preliminary data indicate that Otezla XR maintains similar efficacy to traditional Otezla but improves adherence through extended-release formulation.
What is the market landscape and competitive positioning?
Market Size:
- The global psoriasis market was valued at USD 13.1 billion in 2021.
- Psoriatic arthritis market reached USD 8.4 billion in 2022.
