Business Context and Reporting Period
This Form 6-K filing by Prana Biotechnology Limited (not Alteryx Therapeutics Ltd) covers the month of March 2014. The document primarily summarizes a presentation delivered at the 34th Annual Cowen Healthcare Conference (March 3-5, 2014). Prana is a biotechnology company focused on developing Metal Protein Attenuating Compounds (MPACs), specifically PBT2, for the treatment of neurodegenerative diseases including Alzheimer's disease (AD) and Huntington's disease (HD).
Key Financial Metrics
The filing provides limited financial data, primarily reflecting the company's status as a pre-revenue clinical-stage biotechnology firm.
- Cash Position: As of December 31, 2013, the company held approximately $19.3 million in cash.
- Market Capitalization: Approximately AU$500 million (US$440 million) as of February 28, 2014.

- Revenue and Profit: The filing text does not provide specific revenue, profit, or cash flow figures for the reporting period, consistent with a company in the clinical trial phase.
- Debt and Liquidity: No specific debt figures are provided; liquidity is indicated by the cash balance of $19.3 million.
Material Changes and Clinical Progress
The filing highlights significant clinical milestones and trial results rather than financial changes:
- Alzheimer's Disease (AD):
- Phase 2a Results: Confirmed PBT2 was safe and well-tolerated. The 250mg dose showed significant improvement in Executive Function (p=0.042) and a decrease in CSF Aβ42 (p=0.006).
- Phase 2b IMAGINE Trial: Completed in December 2013 with a 95% retention rate. Results were expected in March 2014.
- Extension Study: An open-label extension study began in July 2013, with 83% of eligible patients enrolling. Final data expected in the first half of 2015.
- Huntington's Disease (HD):
- Reach2HD Phase 2 Results: The 250mg dose significantly improved cognition (Trail Making Test Part B) at 12 weeks (p<0.001) and 26 weeks (p=0.042). This marked the first demonstration of cognitive improvement in an HD clinical trial.
- Safety: PBT2 was well-tolerated over 26 weeks.
- Imaging: A small sub-study suggested reduced brain atrophy in patients exposed to PBT2.
Guidance, Outlook, and Risks
Outlook and Strategy:
- HD Path to Market: The company is preparing to advance PBT2 into a confirmatory Phase 3 clinical trial for Huntington's disease, targeting a New Drug Application (NDA) filing in 2016/2017.
- Pipeline: Beyond PBT2, the company has a library of over 1,000 compounds. PBT434 and PBT519 are in screening/preclinical stages for Parkinson's disease and glioblastoma, respectively.
- AD Catalyst: The release of Phase 2b IMAGINE trial results in March 2014 was identified as a key near-term catalyst.
- Forward-Looking Statements: The filing includes a safe harbor warning that actual results may differ materially from projections due to risks and uncertainties.
- Clinical Risk: Success depends on the positive outcomes of ongoing and future clinical trials (Phase 2b AD results and Phase 3 HD trials).
- Regulatory Risk: Approval by the FDA and other regulatory bodies is required for commercialization.
- The filing notes that the registrant is not furnishing information pursuant to Rule 12g3-2(b).
Investor Verification Checklist
- Verify the release date and specific data points of the Phase 2b IMAGINE trial results for Alzheimer's disease, which were expected in March 2014.
- Confirm the timeline and design of the proposed Phase 3 trial for Huntington's disease and the projected NDA filing date of 2016/2017.
- Review the company's cash burn rate and runway, given the $19.3 million cash balance as of December 2013 and the capital-intensive nature of Phase 3 trials.
- Assess the competitive landscape for Huntington's disease treatments, noting that only tetrabenazine is currently approved and it addresses only motor symptoms.
- Monitor the progress of the open-label extension study for AD, with final data expected in 1H 2015.
