This study evaluates the combined use of Talazoparib and Avelumab in patients with stage IV or recurrent non-squamous non-small cell lung cancer that carries an STK11 gene mutation. It enrolled patients whose tumors had an STK11 mutation and who had received at least one prior anti-PD-1/PD-L1 therapy. The study was conducted in Phase 2 and has been completed.

Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: * Patients must be assigned to S1900C. Assignment to S1900C is determined by the LUNGMAP protocol genomic profiling using the FoundationOne assay. Biomarker eligibility for S1900C is based on the identification of a pathogenic somatic mutation in STK11 or STK11 bi-allelic loss on tumor * Patients must have histologically or cytologically confirmed stage IV or recurrent non-squamous, mixed squamous/non-squamous (e.g., adeno-squamous carcinoma), or non-small cell lung cancer not otherwise specified (NSCLC NOS).

Patients with HCV infection who are currently on treatment must have an undetectable HCV viral load within 28 days prior to sub-study registration * Patients with known human immunodeficiency virus (HIV) infection are eligible, provided they are on effective anti-retroviral therapy and have undetectable viral load at their most recent viral load test and within 6 months prior to sub-study registration * Patients must have received at least one line of anti-PD-1 or anti-PD-L1 therapy for stage III, IV or recurrent disease. Any number of additional, non-platinum-based chemotherapy or targeted therapy regimens for recurrent or metastatic disease are allowed * Patients may not have received more than one line of anti-PD-1 or anti-PD-L1 therapy in the Stage IV or recurrent setting. Anti-PD-1 or anti-PD-L1 therapy may have been given alone or in combination with platinum-based chemotherapy, an anti-CTLA4 therapy, or other immune-modulatory therapy.

The CT from a combined positron emission tomography (PET)/CT may be used to document only non-measurable disease unless it is of diagnostic quality. Measurable disease must be assessed within 28 days prior to sub-study registration. Pleural effusions, ascites and laboratory parameters are not acceptable as the only evidence of disease. Non-measurable disease must be assessed within 42 days prior to sub-study registration. All disease must be assessed and documented on the Baseline Tumor Assessment Form. Patients whose only measurable disease is within a previous radiation therapy port must demonstrate clearly progressive disease (in the opinion of the treating investigator) prior to sub-study registration.

Patient must have fully recovered from the effects of prior surgery in the opinion of the treating investigator * Serum bilirubin =\< institutional upper limit of normal (IULN) (within 28 days prior to sub-study registration). For patients with liver metastases, bilirubin must be =\< 5 x IULN * Either alanine aminotransferase (ALT) or aspartate aminotransferase (AST) =\< 2 x IULN within 28 days prior to sub-study registration (if both ALT and AST are done, both must be =\< 2 IULN).

Women/men of reproductive potential must have agreed to use an effective contraceptive method. A woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months. In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation.
