Neuren Confirms Endpoints for Phase III Study in PMS

20210209pharmaxis

Neuren Pharmaceuticals (NEU: $10.53) has confirmed that the FDA has signed off on co-primary endpoints for its Phase 3 trial exploring NNZ-2591 in Phelan-McDermid syndrome (PMS), a rare neurodevelopmental disorder.

Endpoints Chosen

The endpoints agreed to are in line with expectations, matching those used in Neuren's Phase II study. They are changes in VABS-3, and changes in PMSA-C (previously called CGI-I). The former is assessed by the caregiver and the latter by the clinician.

FDA Type C Meetings

Although investors often take these FDA Type C meetings for granted, the Agency could have requested another Phase 2 study, asked for evidence to support other endpoints, or rejected the endpoints outright. Instead, Neuren received a clear green light to proceed, expecting to start as scheduled in mid 2025.

Another positive outcome for the study, which was previously agreed to by the FDA, is that patients will be treated for just 13 weeks. The trial in Rett syndrome with DAYBUE conducted by Neuren's partner Acadia Pharmaceuticals took 22 months to recruit the 180 patients, which included a three month pause in the trial due to the pandemic. The participants were also treated for 13 weeks.

Results from this study can likely be expected in 2027.

 

Precedent for NNZ-2591

The choice of endpoints relied heavily on strong Phase II data where 16 of 18 children showed clinically-meaningful gains in both VABS-3 and PMSA-C. The average PSMA-C score improved from an average 4 per patient to 2.3, which was approaching ëMuch improvedí overall. This is a full point better than the 3.5 that DAYBUE achieved in its pivotal LAVENDER trial. Early signals also suggest a better safety profile for NNZ-2591 than trofinetide.

Fifth Indication for NNZ-2591

Neuren has also recently announced an additional indication for NNZ-2591, that being to treat newborns who have been deprived of oxygen around birth The condition is called hypoxic-ischemic encephalopathy. NNZ-2591 could be used as a short and long term therapy to restore proper IGF-1 levels in the brain. A Phase II study is likely to start next year under an IND.

Share Buyback

As of mid-April, Neuren has repurchased 2.1% of its issued shares, through a share buyback. This has cost just under $32 million, with the shares bought between $9.79 - $13.61.

Neuren is capitalised at $1.35 billion with $359 million in cash at the end of last year.
