Details and patient eligibility

About

The researchers are doing this study to see if sotorasib is a safe and effective treatment for people with advanced non-small cell lung cancer (NSCLC) with a KRAS G12C mutation who have not received treatment for their cancer since it became advanced. (Participants have not received a "first-line therapy" since their cancer became advanced.)

Inclusion criteria

Written informed consent
Biopsy-proven metastatic or recurrent non-small cell lung cancer
KRAS G12C mutation on prior tumor biopsy or cell-free DNA (cfDNA) testing
No prior therapy in the advanced setting
Measurable disease per RECIST 1.1
Karnofsky performance status (KPS) ≥ 70%
Age ≥ 18
Adequate organ function
- Hemoglobin ≥ 9^9 g/dL
- Platelets ≥ 75 x 10^9/L
- Absolute neutrophil count (ANC) > 1.5 x 10^9/L
- AST < 3 x ULN (if liver metastases are present, < 5 x ULN)
- ALT < 3 x ULN (if liver metastases are present, < 5 x ULN)
- Alkaline phosphatase < 2 x ULN (if liver or bone metastases are present,< 3 xULN)
- Total bilirubin ≤1.5 x ULN; subjects with Gilbert's syndrome can enroll if conjugated bilirubin is within normal limits
- Serum creatinine < 1.5 x ULN or if available, calculated or measured creatinine clearance > 30 mL/min/1.73 m^2

In addition, patients must:

Be willing to undergo pre-treatment and day 7-21 on-treatment tumor biopsies
Decline first-line chemotherapy and/or anti-PD-(L)1 therapy, or previously have experienced disease progression after adjuvant or consolidation chemotherapy or anti-PD-(L)1 therapy for early stage (I-III) NSCLC

Before enrollment, a woman must be either:

Not of childbearing potential: premenarchal; postmenopausal (>45 years of age with amenorrhea for at least 12 months); post-hysterectomy, bilateral salpingectomy, bilateral oophorectomy); or otherwise be incapable of pregnancy
Of childbearing potential and practicing effective method(s) of birth control consistent with local regulations regarding the use of birth control methods for subjects participating in clinical studies, as described below:
- Practicing true abstinence (when this is in line with the preferred and usual lifestyle of the subject), which is defined as refraining from heterosexual intercourse during the entire period of the study, including up to 6 months after the last dose of study drug is given. Periodic abstinence (calendar, symptothermal, post-ovulation methods) is not consider an acceptable contraceptive method
Have a sole partner who is vasectomized
Practicing 2 methods of contraception, including one highly effective method (i.e., established use of oral, injected or implanted hormonal methods of contraception; placement of intrauterine device [IUD] or intrauterine system [IUS], AND, a second method (e.g., condom with spermicidal foam/gel/film/cream/suppository or collusive cap [diaphragm or cervical/vault caps] with spermicidal foam/gel/film/ cream/suppository) Subjects must agree to continue contraception throughout the study and continuing through at least 7 days after the last dose of study drug
NOTE: If the childbearing potential changes after start of the study (e.g., woman who is not heterosexually active becomes active, premenarchal woman experiences menarche) the woman must begin a highly effective method of birth control, as described above.
A woman of childbearing potential must have a negative serum (b-human chorionic gonadotropin [b-hCG]) at Screening
A man who is sexually active with a woman of childbearing potential must agree to use a condom with spermicidal foam/gel/film/cream/suppository and his partner must also be practicing a highly effective method of contraception (i.e., established use of oral, injected or implanted hormonal methods of required to use contraception. The subject must also not donate sperm during the study and for at least 7 days after receiving the last dose of study drug.

contraception; placement of an intrauterine device [IUD] or intrauterine system [IUS]). If the subject is vasectomized, he must still use a condom (with or without spermicide), but his female partner is not required to use contraception. The subject must also not donate sperm during the study and for at least 7 days after receiving the last dose of study drug.

Exclusion criteria

Symptomatic brain metastases
Any radiotherapy within 1 week of starting treatment on protocol
Any major surgery within 1 week of starting treatment on protocol
Exposure to prior adjuvant or consolidation anti-PD-1 or PD-(L)1 therapy for stage I-III disease within 12 weeks of start of initiation of sotorasib
Unresolved > grade 1 toxicity from any previous treatment
Prior history of > grade 1 pneumonitis from any previous treatment
Congestive heart failure defined as New York Heart Association (NYHA) Class III-IV or hospitalization for congestive heart failure (any NYHA class) within 6 months of study Day 1 Gastrointestinal (GI) tract disease causing the inability to take oral medication, malabsorption syndrome, requirement for intravenous alimentation, uncontrolled inflammatory GI disease (eg, Crohn's disease, ulcerative colitis)
Positive hepatitis B (hepatitis B virus [HBV]) surface antigen (HBsAg) o NOTE: Subjects with a prior history of HBV demonstrated by positive hepatitis B core antibody are eligible if they have at Screening 1) a negative HBsAg and 2) a HBV DNA (viral load) below the lower limit of quantification, per local testing. Subjects with a positive HBsAg due to recent vaccination are eligible if HBV DNA (viral load) is below the lower limit of quantification, per local testing.

Positive hepatitis C antibody (anti-HCV)

o NOTE: Subjects with a prior history of HCV, who have completed antiviral treatment and have subsequently documented HCV RNA below the lower limit of quantification per local testing are eligible.

Other clinically active or chronic liver disease
Currently enrolled in another investigational device or drug study, or less than 28 days since ending another investigational device or drug study(s), or receiving other investigational agent(s)
Use of known cytochrome P450 (CYP) 3A4 sensitive substrates (with a narrow therapeutic window), within 14 days or 5 half-lives (whichever is longer) of the drug or its major active metabolite, whichever is longer, prior to study day 1 that was not reviewed and approved by the principal investigator
Use of strong inducers of CYP3A4 within 14 days or 5 half-lives (whichever is longer) prior to study day 1 that was not reviewed and approved by the principal investigator
Use of P-gp substrates within 14 days or 5 half-lives (whichever is longer) prior to study day 1 that was not reviewed and approved by the principal investigator
Patients who do not agree to pre-treatment and on-treatment tumor biopsies during the informed consent process will be excluded from the study. Patients who agree to pre-treatment and on-treatment tumor biopsies, but in whom either biopsy is ultimately deemed unsafe by the investigators/treatment team, will be allowed to participate in the study and will remain evaluable for the clinical endpoints.
