ACADIA's Pipeline Milestones and Upcoming Data Readouts
ACADIA showcased nine disclosed pipeline programs during its R&D Day, with five Phase II or III data readouts expected through 2027.
Key upcoming milestones include initiating a Phase II study of ACP-204 in Lewy body dementia psychosis in Q3 2025 and top-line results from the COMPASS PWS Phase III study in Q4 2025.
The company plans to start a Phase III study of trofinetide in Rett syndrome in Japan in Q3 2025 and a first-in-human study of ACP-271 before year-end.
Progress in the pipeline underscores ACADIA's strategic focus on expanding indications and leveraging novel biology, with multiple data readouts potentially transforming its market position.
FDA Approval and Launch Readiness of Paltusotine (PALSONIFY)
Crinetics' NDA for paltusotine (PALSONIFY) remains on track with an anticipated FDA approval in September 2025.
The company has assembled a highly experienced launch team and is preparing for a transformational market entry.
Engagement with patient communities and advocacy groups has reinforced confidence that PALSONIFY addresses a critical unmet need in acromegaly treatment.
The launch is expected to be gradual, with formulary placement taking 6-9 months post-approval and patient adoption aligning with infrequent endocrinologist visits (2-4 times/year).
Commercial preparations include a dedicated sales force of approximately 30 representatives and ongoing payer discussions emphasizing PALSONIFY's value proposition of rapid disease control and convenience.
Crinetics is actively working on international expansion, targeting a European launch in 2026.
Pipeline Progress and Key Study Readouts in 2025-2026
Mirum's pipeline is advancing rapidly, with three pivotal studies expected to read out over the next 24 months, including the VISTAS Phase IIb study in PSC, with topline data expected in Q2 2026.
The VISTAS study is on track to complete enrollment this quarter, with interim analysis last year providing confidence in IBAT inhibition's potential in PSC.
Additional studies, VANTAGE in PBC and EXPAND in cholestatic pruritus, are progressing well, with enrollment expected to complete in 2026.
The company is also initiating a Phase II study of MRM-3379 for Fragile X syndrome, with FDA feedback received and enrollment planned to start by year-end.
FDA Label Expansion for EMPAVELI in C3G and Primary IC-MPGN
FDA approved a label expansion for EMPAVELI for patients 12 years and older with C3 myelopathy and primary immune complex membranoproliferative glomerulonephritis (IC-MPGN).
This is the company's third FDA approval in 4 years, highlighting scientific strength and regulatory success.
The approval enables treatment with a C3-targeting therapy that achieves outcomes across proteinuria reduction, eGFR stabilization, and C3 deposit clearance.
Launch is underway, expanding into rare nephrology and underserved populations, including pediatric patients and post-transplant recurrence.
Transition to Clinical-Stage Biotech with First Clinical Trials
AbCellera achieved a major milestone by receiving Health Canada authorization to initiate its first two clinical trials for ABCL635 and ABCL575.
Dosing has begun in the Phase I trial for ABCL635, targeting moderate to severe vasomotor symptoms, marking a shift from platform to clinical-stage biotech.
A second Phase I trial for ABCL575 was also initiated, with dosing expected to start shortly, expanding the company's clinical pipeline.
The company added a third program, ABCL688, into IND-enabling studies, indicating ongoing pipeline expansion and transition into more advanced clinical development.
Progress and Challenges in Pulmonary Fibrosis (IPF) and Nebulized Tyvaso Trials
United Therapeutics is on the cusp of reporting results from the TETON 2 study in September, evaluating nebulized Tyvaso in IPF patients outside the U.S. and Canada.
TETON 2 involves 597 patients, with primary endpoint being change in FVC at 52 weeks.
The company aims to support a regulatory filing with the FDA for IPF indication in 2027 if results are successful.
The study design includes efforts to reduce variability in FVC measurements through central reading and standardized procedures.
Successful U.S. Launch of AMVUTTRA for ATTR-CM and Early Market Penetration
Alnylam reported a rapid and broad uptake of AMVUTTRA in the U.S. within just the first full quarter post-launch, with approximately 1,400 patients treated by June 30, 2025.
The launch has exceeded initial expectations, with coverage and access achieved faster than anticipated across major health systems and payers.
Nearly all of the 170 priority health systems now have formulary access to AMVUTTRA, enabling treatment initiation in a majority of ATTR-CM patients.
Early utilization data shows a balanced mix of first-line and stabilizer-progressing patients, with prescriber base tripling quarter-over-quarter, indicating strong physician confidence.
