Carfilzomib in Combination With Sotorasib for the Treatment of Patients With KRAS G12C Mutated Advanced or Metastatic Non-small Cell Lung Cancer

Recruiting now · Phase 1

Conditions studied: Advanced Lung Non-Small Cell Carcinoma, Metastatic Lung Non-Small Cell Carcinoma, Stage III Lung Cancer AJCC v8, Stage IV Lung Cancer AJCC v8

In brief

This phase I trial tests the safety, side effects, and best dose of carfilzomib in combination with sotorasib in treating patients with KRAS G12C-mutated non-small cell lung cancer (NSCLC) that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Carfilzomib is a drug that binds to and inhibits the activity of the protein complex that is responsible for degrading other damaged or unneeded proteins. The inhibition of this protein by carfilzomib can then cause tumor growth inhibition and cell death. Sotorasib is a drug that binds to and inhibits the activity of the KRAS G12C mutant. This may inhibit growth in KRAS G12C-expressing tumor cells. Combining carfilzomib and sotorasib may be a safe and effective treatment option for patients with KRAS G12C-mutated advanced or metastatic NSCLC.

You may qualify if…

Documented informed consent of the participant and/or legally authorized representative
Age: ≥ 18 years
Eastern Cooperative Oncology Group (ECOG) ≤ 2
Histologically confirmed NSCLC that is metastatic or advanced. The tumor must exhibit evidence of KRASG12C mutation which is determined by either a Clinical Laboratory Improvement Act (CLIA) certified ctDNA assay or by a CLIA certified tumor tissue assay
Measurable disease by RECIST v1.1
Failed prior KRAS inhibitor
Fully recovered from the acute toxic effects (except alopecia) from prior anti-cancer therapy
Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
Patients with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate central nervous system (CNS) specific treatment is not required and is unlikely to be required during the first cycle of therapy
Absolute neutrophil count (ANC) ≥ 1,500/mm\^3 (performed within 14 days prior to day 1 of protocol therapy)
NOTE: Growth factor is not permitted within 14 days of ANC assessment unless cytopenia is secondary to disease involvement
Hemoglobin (Hb) ≥ 9 g/dL (performed within 14 days prior to day 1 of protocol therapy)
Platelets ≥ 100,000/mm\^3 (performed within 14 days prior to day 1 of protocol therapy)
NOTE: Platelet transfusions are not permitted within 14 days of platelet assessment unless cytopenia is secondary to disease involvement
Total bilirubin ≤ 1.5 x upper limit of normal (ULN) (unless has Gilbert's disease) (performed within 14 days prior to day 1 of protocol therapy)
Aspartate aminotransferase (AST) ≤ 3 x ULN (or ≤ 5 x ULN in the setting of liver metastatic disease) (performed within 14 days prior to day 1 of protocol therapy)
Alanine aminotransferase (ALT) ≤ 5 x ULN (or ≤ 5 x ULN in the setting of liver metastatic disease) (performed within 14 days prior to day 1 of protocol therapy)
Creatinine clearance of ≤ 1.5 x ULN or glomerular filtration rate (GFR) ≥ 60 mL/min/1.73 m\^2 (performed within 14 days prior to day 1 of protocol therapy)
Women of childbearing potential (WOCBP): negative urine or serum pregnancy test (performed within 14 days prior to day 1 of protocol therapy)
If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
Agreement by females and males of childbearing potential to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 120 days after the last dose of protocol therapy.
Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for > 1 year (women only)

You may not qualify if…

Chemotherapy or immunotherapy within 21 days prior to day 1 of protocol therapy
Radiation therapy within 14 days prior to day 1 of protocol therapy
KRAS inhibitor within 14 days prior to day 1 of protocol therapy
Investigational therapy within 28 days prior to day 1 of protocol therapy (or 5 half-lives, use whichever is shorter)
Inability to previously tolerate (240 mg, QD) sotorasib
History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agent
Clinically significant uncontrolled illness
Evidence of chronic hepatitis B virus (HBV) infection and HBV viral load detectable
Evidence of untreated chronic hepatitis C virus (HCV) infection. Patients with HCV infection currently on treatment are eligible if they have an undetectable HCV viral load
Active infection requiring antibiotics (not to be completed by day 1 of protocol therapy)
Known history of immunodeficiency virus (HIV) with detectable viral load
Prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen
New York Heart Association (NYHA) class III or IV heart failure, myocardial infarction in the preceding 6 months, conduction abnormalities uncontrolled by medications
Females only: Pregnant or breastfeeding
Any other condition that would, in the investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures
Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
