EPIK-P1: Retrospective Chart Review Study of Patients (pts) With PIK3CA-Related Overgrowth Spectrum (PROS) Who Have Received Alpelisib (ALP) as Part of a Compassionate Use Programme
G. Canaud, et al.
Conclusions
The real-world evidence from the EPIK-P1 study demonstrates that ALP confers clinically meaningful efficacy to, and is well tolerated in, pts with PROS.

Interim results from a phase 2 study of the ATR inhibitor ceralasertib in ARID1A-deficient and ARID1A-intact advanced solid tumor malignancies
R. Aggarwal, et al.
Conclusions
We observed anti-tumor activity with single agent ceralasertib in ARID1A-deficient solid tumors, including two patients with durable and ongoing complete responses. Accrual is ongoing in stage 2 using absence of BAF250a expression by IHC for patient selection.

A phase 1/2 multicenter, first-in-human study of DS-7300 (B7-H3 DXd-ADC) in patients (pts) with advanced solid tumors
M.L. Johnson, et al.
Conclusions
DS-7300 was generally well tolerated with early signs of clinical activity, including objective responses, in pts with pretreated advanced solid tumors. Expansion cohorts are currently enrolling to evaluate DS-7300 in selected tumor types.
