NCT05501886 (Gedatolisib in PIK3CA WT and MT advanced or…): BVCT ex-ante prediction vs. reported outcome

On 27 Mar 2025, BioinvestGPT's BVCT predicted technical partial success and commercial partial failure for this trial. The 20 Oct 2025 readout is classified on the dashboard as True Negative (TN), a correct prediction. Recorded clinical-benefit conclusion: statistically significant (superior mPFS) and commercially insufficient (non-superior mOS).

partial FAILURE (commercially insufficient additive clinical benefit in OS for gedatolisib + fulvestrant + palbociclib at most numerically superior to SoC alpelisib + fulvestrant for PIK3CA MT population and non-superior to SoC fulvestrant for PIK3CA WT population despite with additional gedatolisib-related toxicity) FAILURE (commercially insufficient additive clinical benefit in OS for gedatolisib + fulvestrant non-inferior to SoC for both PIK3CA MT population PIK3CA WT population with additional gedatolisib-related toxicity)
Technical Prediction
partial SUCCESS (statistically significant yet moderate additive clinical benefit in ORR/PFS for gedatolisib + fulvestrant + palbociclib moderately superior to SoC alpelisib + fulvestrant for PIK3CA MT population slightly superior to SoC fulvestrant for PIK3CA WT population despite with additional gedatolisib-related toxicity) partial FAILURE (statistically insignificant additive clinical benefit in ORR/PFS for gedatolisib + fulvestrant non-superior to SoC fulvestrant for both PIK3CA MT population and PIK3CA WT with additional gedatolisib-related toxicity)
