Targeted Treatment for RET Fusion-Positive Advanced Non-Small Cell Lung Cancer (A LUNG-MAP Treatment Trial)

Stage IV Lung Cancer AJCC v8 Clinical Trial

Official title: A Phase II Study of LOXO-292 in Patients With RET Fusion-Positive Stage IV or Recurrent Non-Small Cell Lung Cancer (LUNG-MAP Sub-Study)

Status Active, not recruiting

Clinical Trial Summary

This phase II LUNG-MAP treatment trial studies how well selpercatinib works in treating patients with RET fusion-positive non-small cell lung cancer that is stage IV or has come back (recurrent). Selpercatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Clinical Trial Description

PRIMARY OBJECTIVE:

I. To evaluate the objective response rate (ORR) (confirmed complete or partial response) by blinded independent centralized review (BICR) associated with selpercatinib (LOXO-292) in patients with previously-treated stage IV or recurrent RET fusion-positive non-small cell lung cancer (NSCLC).

SECONDARY OBJECTIVES:

I. To evaluate the duration of BICR-assessed response among BICR responders. II. To evaluate the frequency and severity of toxicities. III. To evaluate the investigator-assessed objective response rate (confirmed complete or partial response).

IV. To evaluate duration of investigator-assessed response among patients with a response as determined by the local investigator.

V. To evaluate investigator-assessed progression-free survival (IA-PFS). VI. To evaluate BICR-assessed PFS. VII. To evaluate overall survival (OS).

VIII. Among patients with brain metastases at baseline:

VIIIa. To evaluate the central nervous system (CNS) response rate (confirmed complete response [CR]).

VIIIb. To evaluate the duration of intracranial response among patients with a CNS response.

TRANSLATIONAL MEDICINE OBJECTIVES:

I. To collect, process, and bank cell-free deoxyribonucleic acid (cfDNA) at baseline, progression, and end of treatment for future development of a proposal to evaluate comprehensive next-generation sequencing of circulating tumor deoxyribonucleic acid (ctDNA).

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

OUTLINE:

Patients receive selpercatinib orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for 2 years and then at the end of 3 years from date of sub-study registration. ;
