Groups of patients will receive increasing doses of HMBD-001 as a single agent to find a safe dose that best targets cancer cells. Approximately 26 patients with tumours known to express HER3 will be entered into this arm.

An expansion cohort of up to 25 patients with a confirmed HER3 positive or confirmed NRG1 fusion rearrangement RAS wild type colorectal cancer, castration resistant prostate cancer, triple negative breast cancer or squamous cell head and neck cancer will receive the HMBD-001 single agent RP2D as determined in Part A Arm 1.

Intravenous infusion given over a 21 or 28 day cycle dependent on dosing frequency. Number of cycles: 6 or until disease progression or unacceptable toxicity develops.

This clinical trial is evaluating a drug called HMBD-001 (an anti-HER3 monoclonal antibody) in patients with advanced HER3 positive solid tumours. The main aims are to find out the maximum dose of HMBD-001 that can be given safely to patients alone and in combination with other anti-cancer agents, more about the potential side effects of HMBD-001 and how these can be treated and what happens to HMBD-001 inside the body and how it affects cancer cells.

HMBD-001 is a type of drug called a monoclonal antibody, which works by targeting a protein called HER3, that is found in high numbers in some types of cancers including those which contain NRG1 gene fusions. By attaching itself to this protein it may then work to kill the cancer cells or to stop them growing.

This is a first-in-human clinical trial which has two parts:

Part A is a 'dose escalation' phase where small groups of patients will receive increasing doses of HMBD-001 to find the safest dose which best targets cancer cells.

* In Arm 1, patients will receive HMBD-001 on its own (as a single agent).
* In Arm 2, patients will receive HMBD-001 given with other anti-cancer drugs (in combination).

Part B is a 'dose expansion' phase where larger groups of patients with specific cancer types, known to have high levels of the protein HER3 or a confirmed NRG1 gene fusion will receive the highest doses of HMBD-001 considered to be safe in Part A either alone as single agent or in combination with other anti-cancer drugs.

The main aims of the clinical trial are to find out:

* The highest dose of HMBD-001 alone and in combination with other anti-cancer drugs that can be given safely to patients.
* More about the potential side effects of HMBD-001 when given alone and in combination with other anti-cancer agents and how they can be managed.
* What happens to HMBD-001 inside the body and how it affects cancer cells.
* The potential anti-tumour activity of HMBD-001 as a single agent and in various combination regimens in specific tumour types of HER3 expressing tumours or tumours with NRG1 gene fusions.

This is a phase 1b multi-center, open-label study of HMBD-001 with or without chemotherapy in participants with advanced solid tumors harboring NRG1 gene fusions or selected HER3 mutations.

Study of an Anti-HER3 Antibody, HMBD-001, With or Without Chemotherapy in Patients With Solid Tumors Harboring an NRG1 Fusion or HER3 Mutation

A Phase 1b Study to Evaluate HMBD-001 With or Without Chemotherapy in Participants With Advanced Solid Tumors Harboring NRG1 Gene Fusions or Selected HER3 Mutations

An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered to be related to the study treatment.

DLTs will be assessed during the safety run-in phase and are defined as toxicities that meet pre-defined severity criteria and assessed as having a suspected relationship to study drug, and unrelated to disease, disease progression, intercurrent illness, or concomitant medications that occurs within the first cycle (4 weeks for Arm A, 3 weeks for Arm B) of treatment

The ORR is defined as the proportion of subjects with confirmed CR or confirmed PR, based on RECIST Version 1.1
