Brief Summary

To find a recommended dose of the combination of adagrasib and durvalumab that can be given to patients with cancers that have a KRAS G12C mutation.

Detailed Description

Primary Objectives:

• To determine the safety and tolerability, and to establish the recommended dose of the adagrasib and durvalumab combination in advanced NSCLC or GI cancer patients.

Secondary Objectives:

• To determine the objective response rate of the adagrasib and durvalumab combination for frontline treatment of advanced NSCLC harboring a KRAS G12C mutation.
• To determine the objective response rate of the adagrasib and durvalumab combination for treatment of advanced CRC that have progressed on prior therapy with KRAS G12C inhibitors.
• To determine duration of response (DOR) and progression-free survival (PFS) for the combination of the adagrasib and durvalumab in patients with advanced NSCLC harboring a KRAS G12C mutation.
• To determine DOR and PFS for the combination of the adagrasib and durvalumab in patients with advanced CRC that have progressed on prior therapy with KRAS G12C inhibitors.

Exploratory Objectives:

• To assess predictive biomarkers of response and resistance to the combination of adagrasib and durvalumab.
• To assess mechanisms of tumor cell adaptation upon treatment with the combination of adagrasib and durvalumab.
• To determine mechanisms of acquired resistance to the combination of adagrasib and durvalumab.
• To assess the effect of the combination of adagrasib and durvalumab on the immune tumor microenvironment.
• To generate cell lines and patient derived xenograft (PDX) models from tumor samples.
• To assess the anti-tumor reactivity of tumor infiltrating lymphocytes (TIL) from tumor biopsies.

Eligibility Criteria

Inclusion Criteria

1. For the dose confirmation cohort, histologically confirmed diagnosis of NSCLC or carcinomas of gastro-intestinal tract, including, but not limited to, colorectal adenocarcinoma, pancreatic adenocarcinoma, and cholangiocarcinoma. For the Dose Expansion cohorts, only NSCLC and colorectal adenocarcinoma histologies are eligible.

2. Presence of KRAS G12C mutation detected by assay performed in a CLIA-certified environment.

3. Metastatic disease or locally advanced disease not amenable to local therapy.

4. ECOG performance status 0 or 1.

5. Presence of measurable disease per RECIST v1.1.

6. Any number of prior lines of therapy, including prior KRAS G12C inhibitor. For the Dose Expansion cohorts, only treatment naïve NSCLC patients and colorectal adenocarcinoma patients with disease progression on prior KRAS G12Ci are eligible. NSCLC patients that completed curative intent treatment of their disease ≥6 months prior to enrollment are eligible for frontline expansion cohort as long as they have not been previously treated with a KRAS G12C inhibitor.

7. Age ≥ 18 years.

8. Life expectancy of at least 3 months.

9. Most recent prior systemic therapy (e.g., chemotherapy, immunotherapy or, investigational agent) and radiation therapy discontinued at least 2 weeks before first dose date.

10. Recovery from the adverse effects of prior therapy at the time of enrollment to ≤ Grade 1 (excluding alopecia and parameters superseded by other eligibility criteria [eg, laboratory parameters]).

11. Laboratory values within the screening period:

• Absolute neutrophil count ≥ 1,000/mm3 (≥ 1.0 x 109/L)
• Platelet count ≥ 100,000/mm3 (≥ 100 x 109/L)
• Hemoglobin ≥ 9 g/dL
• Total bilirubin ≤ 1.5 x Upper Limit of Normal (ULN) (if associated with liver metastases or Gilbert's disease, ≤ 3 x ULN)
• Aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 3.0 x ULN (if associated with liver metastases, ≤ 5 x ULN)
• Creatinine clearance ≥50 mL/min calculated using a validated prediction equation (e.g., Cockcroft-Gault, MDRD, or 24-hour urine CrCl).

12. Women of child-bearing potential (WOCBP) or men whose partner is a WOCBP agrees to use contraception while participating in this study, and for a period of 6 months following termination of study treatment (see Reproductive Health below).

13. Completed informed consent process, including signing IRB/EC-approved informed consent form.

14. Willing to comply with clinical trial instructions and requirements. Reproductive Health

Patients who are biologically capable of having children and sexually active must agree to use an acceptable method of contraception for the duration of the treatment period and for at least 6 months after the last dose of study treatment. The Investigator will counsel the patient on selection of contraception method and instruct the patient in its consistent and correct use. Examples of acceptable forms of contraception include:

• Oral, inserted, injected or implanted hormonal methods of contraception, provided it has been used for an adequate period of time to ensure effectiveness.
• Correctly placed copper containing intrauterine device (IUD).
• Male condom or female condom used WITH a spermicide.
• Male sterilization with confirmed absence of sperm in the post-vasectomy ejaculate.
• Bilateral tubal ligation or bilateral salpingectomy. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control.

The Investigator will instruct the patient to call immediately if the selected birth control method is discontinued or if pregnancy is known or suspected.

Note: Women are considered post-menopausal and/or not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or have had surgical
