Combination Treatment (Talazoparib Plus Avelumab) for Stage IV or Recurrent Non-Squamous Non-Small Cell Lung Cancer With STK11 Gene Mutation (A LUNG-MAP Treatment Trial)

Stage IV Lung Cancer AJCC v8 Clinical Trial

Official title: A Phase II Study of Talazoparib Plus Avelumab in Patients With Stage IV or Recurrent Non-Squamous Non-Small Cell Lung Cancer Bearing Pathogenic STK11 Genomic Alterations (LUNG-MAP Sub-Study)

Status Active, not recruiting

Clinical Trial Summary

This phase II LUNG-MAP treatment trial studies how well combination treatment (talazoparib plus avelumab) works in treating patients with non-squamous non-small cell lung cancer that has an STK11 gene mutation and has come back (recurrent) or is stage IV. Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Immunotherapy drugs given as single therapies or in combination with chemotherapy do not appear to work as well in lung cancer cells with mutations in the STK11 gene versus those that do not have the mutation. Adding the medicine talazoparib to the immunotherapy drug avelumab may work better in treating lung cancers that have an STK11 gene mutation.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To evaluate the objective response rate (ORR) (confirmed and unconfirmed, complete and partial) with talazoparib plus avelumab in patients with stage IV or recurrent non-squamous non-small cell lung cancer bearing pathogenic STK11 genomic alterations that were previously-treated with anti-PD-1/PD-L1 therapy and platinum-based chemotherapy.

II. To evaluate disease control rate at 12 weeks (DCR12) after registration.

SECONDARY OBJECTIVES:

I. To evaluate investigator assessed progression-free survival (IA-PFS). II. To evaluate overall survival (OS). III. To evaluate duration of response (DOR) among responders. IV. To evaluate the frequency and severity of toxicities.

TRANSLATIONAL MEDICINE OBJECTIVES:

I. To collect, process, and bank cell-free deoxyribonucleic acid (DNA) (cfDNA) at baseline, cycle 3 day 1, progression, and end of treatment for future development of a proposal to evaluate comprehensive next-generation sequencing of circulating tumor DNA (ctDNA) and examine molecular mechanisms of resistance to talazoparib and avelumab.

II. To establish a tissue/blood repository from patients with refractory non-small cell lung cancer (NSCLC).

III. To evaluate clinical outcomes (ORR, IA-PFS, OS) in patients with concurrent somatic mutations in KEAP1 detected on the Foundation Medicine Inc. (FMI) panel from the LUNGMAP screening protocol.

IV. To evaluate clinical outcomes (ORR, IA-PFS, OS) in patients with concurrent mutations in ATM or other DNA damage response genes detected on the FMI panel from the LUNGMAP screening protocol.

V. To evaluate the association between tumor mutational burden (TMB) measured on the FMI panel from the LUNGMAP screening protocol and clinical outcomes (ORR, IA-PFS, OS).

OUTLINE:

Patients receive talazoparib orally (PO) daily and avelumab intravenously (IV) over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up until death or 3 years after sub-study registration. ;
