Primary

MeasureTime frameDescription
Part A: To characterize the safety, tolerability, and AE profile of escalating doses of VS-7375Up to 2.5 yearsTo characterize the safety, tolerability, and AE profile of escalating doses of VS-7375 administered on a daily oral schedule in participants with advanced solid tumors harboring a KRAS G12D mutation. Proportion/number of participants with AEs, TEAEs, TRAEs, SAEs, DLTs, and dose interruptions/reductions.
Part A: To identify the MTD or MFDCycle 1 (each cycle is 21 days)To identify the MTD or MFD using a BOIN design and recommend a dose for subsequent studies of VS-7375 on a daily oral schedule in participants with any KRAS G12D-mutated solid tumor. Proportion/number of participants with DLTs during the DLT assessment period (through C1D21).
Part B: To evaluate the preliminary anticancer activity of the optimal VS-7375 regimenUp to 2.5 yearsTo evaluate the preliminary anticancer activity of the optimal VS-7375 regimen identified from Part A in participants with advanced KRAS G12D-mutated PDAC (cohort B1), NSCLC (cohort B2), and other solid tumors (cohort B3). Confirmed ORR, PFS rate, unconfirmed PR and CR rates, DCR, DOR, and PFS per RECIST v1.1. Overall Survival
Part C: To characterize the safety, tolerability, and AE profile of VS-7375 in combination regimens.From enrollment to the end of treatment; an average of 9 monthsTo characterize the safety, tolerability, and AE profile of VS-7375 in the following combination regimens in participants with any solid tumor harboring a KRAS G12D mutation. * 2L+ therapy in combination with cetuximab in participants with any advanced or metastatic solid tumor harboring a KRAS G12D mutation * 1L therapy in combination with carboplatin, pembrolizumab, and pemetrexed in participants with previously untreated metastatic NSCLC * 2L+ therapy in combination with gemcitabine and nab-paclitaxel in participants with metastatic PDAC * 1L therapy in combination with gemcitabine in participants aged 75 years or older with previously untreated metastatic PDAC. Proportion/number of participants with AEs, TEAEs, TRAEs, SAEs, DLTs, and dose interruptions/reductions.
Part C: To identify a recommended dose for subsequent studies of combination dosed VS-7375.Cycle 1 (each cycle is 21 or 28 days)To identify a recommended dose for subsequent studies of combination dosed VS-7375. Proportion/number of participants with DLTs during the DLT assessment period (through end of Cycle 1).
Part D: To determine the preliminary anticancer activity of the optimal regimen of VS-7375 as identified in Part CUp to 2.5 yearsTo determine the preliminary anticancer activity of the optimal regimen of VS-7375 as identified in Part C as: * 2L+ therapy in combination with cetuximab in participants with metastatic colorectal adenocarcinoma * 1L therapy in combination with carboplatin, pembrolizumab, and pemetrexed in participants with previously untreated metastatic NSCLC * 2L+ therapy in combination with gemcitabine and nab-paclitaxel in participants with metastatic PDAC * 1L therapy in combination with gemcitabine in participants aged 75 years or older with previously untreated metastatic PDAC. Confirmed ORR, PFS rate, unconfirmed PR and CR rates, DCR, DOR, and PFS per RECIST v1.1. Overall survival
