Study Endpoints

Primary Endpoints

Incidence and Nature of Adverse Events (AEs)
From the time the Informed Consent Form (ICF) is signed until 30 days after last dose of study treatment

Incidence, nature and severity of adverse events (AEs) and serious adverse events (SAEs), changes in laboratory parameters, vital signs and ECG results per NCI CTCAE V5.0 Incidence of dose interruptions and modifications 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

Number of participants with dose-limiting toxicities (DLTs) - applicable to part A
From date of enrollment (first dosing) until the end of Cycle 1 (each cycle is 21 days)

DLTs will be assessed in the dose escalation cohorts 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 (3 weeks) of treatment

Six months progression-free survival (PFS) - applicable to part B
From date of enrollment (first dosing) until disease progression or death, assessed up to 6 months

Number of participants achieving progression-free survival (PFS) at 6 months

Secondary Endpoints

Objective Response Rate (ORR) by Response Evaluation Criteria In Solid Tumors (RECIST) V1.1
From date of enrollment (first dosing) until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 48 months
HMBD-001 serum concentration-time profile and derived PK parameters
From date of enrollment (first dosing) until date of end of treatment from any cause, including multiple treatment cycles (each cycle is 21 days), assessed up to 48 months
HMBD-001 Immunogenicity Profile
From date of enrollment (first dosing) until date of end of treatment from any cause, including multiple treatment cycles (each cycle is 21 days), assessed up to 48 months

Frequently asked questions about HMBD-001

What is HMBD-001 used for in Advanced or Metastatic Squamous Non-Small Cell Lung Cancer?

HMBD-001 is an investigational small molecule being studied for the treatment of advanced or metastatic squamous non-small cell lung cancer. It is currently in Phase 1 clinical development, and its safety and efficacy have not yet been established. The drug is not approved by regulatory authorities.

What does HMBD-001 target?

HMBD-001 is an anti-HER3 antibody, meaning it targets the HER3 receptor. It is being evaluated in combination with cetuximab, with or without docetaxel, in patients with advanced squamous cell cancers, including squamous non-small cell lung cancer. The drug is designed to interfere with HER3 signaling in tumor cells.

Who makes HMBD-001?

HMBD-001 is being developed by Merck & Company, Inc., a pharmaceutical company traded on the New York Stock Exchange under the ticker symbol MRK. The drug is currently in Phase 1 clinical trials and is not yet approved for commercial use.

What phase is HMBD-001 in?

HMBD-001 is in Phase 1 clinical development. It is being studied in an ongoing Phase Ib/II trial, but the drug is still investigational and has not received FDA approval. The trial is currently recruiting participants.

What clinical trials is HMBD-001 in?

HMBD-001 is being evaluated in clinical trial NCT05910827, a Phase Ib/II study of HMBD-001 with cetuximab, with or without docetaxel, in advanced squamous cell cancers. The trial is recruiting and aims to enroll 398 participants across Australia, Moldova, Singapore, South Korea, and Taiwan.

Is HMBD-001 the same as an anti-HER3 antibody?

Yes, HMBD-001 is an anti-HER3 antibody. It is being studied in combination with other therapies for the treatment of advanced squamous cell cancers, including squamous non-small cell lung cancer. The drug is in Phase 1 clinical development and is not yet approved.
