Primary Outcome Measures	Measure Description	Time Frame
Objective Response Rate (ORR)	Clinical activity will be assessed by overall response rate (ORR). ORR is defined as the percentage of patients whose best response is Complete Response (CR) plus those with Partial Response (PR) based on RECIST 1.1.	2 years

Secondary Outcome Measures	Measure Description	Time Frame
Assess Adverse Events	Characterize the safety and tolerability of patients receiving sotorasib combined with chemotherapy for second line treatment of pancreas cancer. Determine safety and tolerability as determined by NCI CTCAE v 5.0	2 months
Progression Free Survival (PFS)	Determine progression free survival (PFS) including the 6- month, 1- year, 2-year and median progression free survival. PFS is defined from the date from first dose of study drug administration (C1D1) until the date of first documentation of progressive disease by RECIST 1.1 or death from any cause, whichever comes first	6 months, 1 year, and 2 years
Duration of Response (DoR)	Determine the Duration of Response (DOR). DOR is defined from the date of first documentation of response to treatment, to the date of first documentation of progressive disease by RECIST 1.1 or death, whichever comes first, in patients who experience a response.	2 years
Disease Control Rate (DCR)	Determine the Disease Control Rate (DCR). DCR is defined as the percentage of patients whose best response is complete response (CR) plus partial response (PR) plus stable disease (SD) by RECIST 1.1.	2 years
Overall Survival (OS)	Determine Overall Survival (OS). OS is assessed from the date of registration to the study until the date of death from any cause for up to 2 years.	2 years
