Non-Small Cell Lung Cancer (NSCLC) Research Study Enrolling Now

If you have been treated for NSCLC, you may qualify
for a research study to learn if an investigational
medication can help to prevent NSCLC from returning.

Study Purpose

The purpose of the LIBRETTO-432 Study is to learn if an investigational drug can help prevent the return of non-small cell lung cancer (NSCLC) in people who have RET in their tumor. RET is an abnormal protein that can be responsible for cancer growth. You do not need to know if you have RET to be screened for this study. We will test you for RET during screening for free.

Currently, there are no drugs targeting RET to help prevent the return of NSCLC after it has been treated. Our study is researching an investigational drug that could help.

Key Details

Phase 3

This is a phase 3 research study. Phase 3 research studies are the third step in a four-step drug approval process. In this phase, scientists test whether an investigational medication is more effective than the standard treatment in people with a specific disease or condition.

Clinicaltrials.gov Study ID: NCT04819100

Highlights

When is the study enrolling participants?

Planned for 2021 - 2027

How many participants are required?

Approximately 170

Will I get the investigational drug?

Participants have:

  • 50% chance of receiving Selpercatinib, the investigational drug
  • 50% chance of receiving placebo

Those who receive a placebo could be eligible to receive Selpercatinib later. Read more about how placebos will be used in the Frequently Asked Questions section below.
