Business, in the company's words. Opening of Item 1 of the 10-K received Mar 31, 2026; the document on sec.gov.

We are a clinical-stage biopharmaceutical company dedicated to the development of novel therapeutics for high unmet medical needs, including treatment-resistant metastatic breast cancer and amyotrophic lateral sclerosis (“ALS”), with the goal of improving patients’ lives. Following a review of potential therapeutic and business opportunities, we acquired rights to a promising late-stage asset, lasofoxifene, for the potential treatment of ESR1-mutated (“mESR1”) metastatic breast cancer in December 2025. This late-stage program has generated promising clinical data and we believe it represents a unique and exciting opportunity to diversify our pipeline.

Limitations [top]

Peer group. Sector assignment from four-digit SIC codes, hand-tuned and published. The grade under three alternative peer policies is tabled above.

Size. Within a sector the letter tracks size. Among graded filers in the smallest asset band, 72% grade E and 0% grade A; in the largest, 13% grade E and 21% grade A. Universe as of Oct 9, 2026.

Failure model. filings 2012-01-01 to 2019-12-31 fit, filings 2020-01-01 to 2025-12-31 test; status post hoc pending confirmation. pre-registered on 2026 filings once their 12-month outcome windows close; supported if the paired per-quintile gain over the pooled model has a lower bound above 0.05.

Input validity. Revenue or total assets at or below $100,000 sets the degenerate-inputs flag. An input whose denominator is at or below $100,000 is left not computable rather than ranked.

Returns. No input on this page has a post-2015 confidence interval on returns that excludes zero. The grade ranks reported financial condition and is not a return forecast.

Informational and educational only. Not investment advice. SEC and market data may contain errors.

If you have any comments about this page, the methodology and every line of code that produced it are in the public repository. However, due to the limited number of personnel, we are unable to provide a direct response.
