Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1/1b open-label, multi-center dose escalation and dose optimization study designed to evaluate the safety and preliminary efficacy of IAM1363 in participants with advanced cancers that harbor HER2 alterations.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1/1b open-label, multi-center study, designed to evaluate IAM1363 in participants with advanced cancers that harbor HER2 alterations.

This study consists of the following 3 parts, which are described in further detail below:

* Part 1 (Monotherapy Dose Escalation)
* Part 2 (Dose Optimization)
* Part 3 (Simon 2-Stage Evaluation)

Part 1 will enroll participants with a confirmed, relapsed/refractory malignancy with documented diagnosis of HER2 alterations including participants with brain metastases. Once a provisional maximum tolerated dose (MTD)/recommended Phase 2 dose (RP2D) has been determined, Part 2 will enroll additional cohorts to optimize dose selection and to further evaluate the safety and preliminary efficacy of IAM1363. Following completion of Dose Optimization, Part 3 will be opened to enroll tumor-specific cohorts utilizing a Simon 2-Stage Minimax Design to evaluate IAM1363 at the selected dose(s).
