A Study of TAK-788 in Adults With Non-Small Cell Lung Cancer

Carcinoma, Non-Small-Cell Lung Clinical Trial

Official title: A Phase 1/2 Study of the Safety, Pharmacokinetics, and Anti-Tumor Activity of the Oral EGFR/HER2 Inhibitor TAK-788 (AP32788) in Non-Small Cell Lung Cancer

Status Active, not recruiting

Clinical Trial Summary

This study is about a medicine called TAK-788, also known as mobocertinib, given to adults with non-small cell lung cancer. The main aims of this study are to check if there are any side effects from TAK-788, to learn how TAK-788 is processed by the body, and to determine the best dose of TAK-788 to treat this condition. Participants will take TAK-788 capsules with chemotherapy. Participants will continue to take TAK-788 unless they or their doctor decide they should stop this treatment. Participants will take TAK-788 capsules with or without chemotherapy under antidiarrhea prevention to determine the safety of TAK-788 treatment. Non-Asian, non-White participants will take TAK-788 to determine the safety and tolerability of TAK-788 treatment.

Clinical Trial Description

This phase 1/2 study will evaluate the safety, pharmacokinetics, and anti-tumor activity of oral EGFR/HER2 Inhibitor TAK-788 in participants with NSCLC and anti-tumor activity of TAK-788 in participants with solid tumors other than NSCLC with EGFR or HER2 mutations. The trial will be conducted in three parts: a dose escalation (Part 1), expansion phase (Part 2), followed by an extension phase (Part 3).

The objectives of the dose escalation phase (Part 1), is to determine the safety profile of orally administered TAK-788, including the MTD, DLTs, RP2D, pharmacokinetic profile. The primary goal of the expansion component of the trial is to evaluate the anti-tumor activity of TAK-788 in seven histologically and molecularly defined cohorts at the RP2D (determined based on dose escalation phase of the trial).

The seven expansion cohorts will be:

1. NSCLC participants with EGFR exon 20 activating insertions, who have either not received or not shown an objective response to an EGFR TKI, and who have no active, measurable CNS metastases;

2. NSCLC participants with HER2 exon 20 activating insertions or point mutations and no active, measurable CNS metastases;

3. NSCLC participants with EGFR exon 20 activating insertions or HER2 exon 20 activating insertions or point mutations and active, measurable CNS metastases;

4. NSCLC participants with other targets against which TAK-788 is active (examples include EGFR exon 19 deletions or exon 21 substitutions [with or without T790M mutations] and other uncommon EGFR activating mutations), without active CNS metastases;

5. NSCLC participants with EGFR exon 20 activating insertions, who have previously shown an objective response to an EGFR TKI and subsequently progressed, without active CNS metastases;

6. NSCLC participants with EGFR exon 20 activating insertions, who have not received prior systemic anticancer treatment for locally advanced or metastatic disease, without active CNS metastases; and

7. Participants with solid tumors other than NSCLC with EGFR/HER2 mutations against which TAK-788 is active, without active CNS metastases.

The extension phase will evaluate efficacy of TAK-788 in participants with locally advanced or metastatic NSCLC whose tumors harbor EGFR exon 20 insertion mutations and who have been previously treated. The study enrolled 324 participants. ;
