Guidance, Outlook, and Risks
Development Milestones
- Q1 2018: GMP Manufacturing.
- Mid-2018: Start of Phase 1 (SAD/MAD) clinical trials.
- 2H 2018: Initiation of Long-Term (LT) Toxicology studies.
- 2H 2019: Submission of New IND.
- 1H 2020: Start of Phase 2 trials.
Management Commentary and Risks
Management positions PBT434 as a potential disease-modifying therapy with a clear path to clinical advancement. The drug is described as having a benign safety profile in GLP toxicology studies, with a non-toxic dose exceeding the efficacious dose by greater than 10-fold. Key risks inherent to the sector include the need for successful clinical trial outcomes and the reliance on future funding to sustain operations through Phase 2.
Investor Verification Checklist
- Verify the sufficiency of the AU$20 million cash balance to fund operations through the projected Phase 2 start in 2020.
- Confirm the timeline for GMP manufacturing and the initiation of Phase 1 trials in mid-2018.
- Review the specific terms and scope of the collaboration with Takeda Pharmaceuticals.
- Assess the competitive landscape for alpha-synuclein targeted therapies, including agents from Roche, Biogen, and others mentioned in the filing.
- Monitor upcoming toxicology data releases to validate the safety profile prior to human trials.
