Description
Summary
Study STX-478-101 is a multipart, open-label, phase 1/2 study evaluating the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of STX-478 in participants with advanced solid tumors with certain mutations.
Part 1 will evaluate STX-478 as monotherapy in participants with advanced solid tumors and breast cancer; Part 2 will evaluate STX-478 therapy as combination therapy with fulvestrant in participants with breast cancer.
Each study part will include a 28-day screening period, followed by treatment with STX-478 monotherapy or combination therapy.

- Has a new or recent tumor biopsy (collected at screening, if feasible) or archival tumor specimen within 10 years prior to screening
- Has a tumor that harbors a documented PI3Kα mutation (cohort specific criterion for cohort-specific mutation types) obtained either from tumor or plasma samples, determined by PCR or NGS-based assay as an FDA-approved test in US, CE marked in EU, or obtained as part of normal clinical care in a CLIA certified or similarly certified laboratory.
