Eligibility
Key inclusion criteria
- Ability to understand and be willing to sign an informed consent form

- Males and females aged over 18 years

- Eastern Cooperative Oncology Group (ECOG) status of 0 to 1

- Histologic or cytologic evidence of an advanced malignant solid that is
resistant/refractory to standard systemic therapy, or for which there is no
standard systemic therapy or reasonable therapy in the physician's judgment
likely to result in clinical benefit, or the participant has demonstrated to be
intolerable to such therapy, or if such therapy has been refused by the
participant

- Arms A, B and C: Cancer harboring an NRG1 gene fusion with EGF-like domain; Arm
A: Participants with locally advanced or metastatic pancreatic adenocarcinoma
that have not received prior treatment with gemcitabine or nab-paclitaxel and /or
have not received more than 2 lines of systemic therapy for advanced disease; Arm
B: Participants with locally advanced or metastatic non-small cell lung cancer
that have not received prior treatment with docetaxel and /or have not received
more than 2 lines of systemic therapy for advanced disease; Arm C: Participants
must not be eligible to participate in Arm A or B

- Arm D: Cancer harboring selected HER3 mutations limited to the extracellular
domain.

- Have an estimated life expectancy of at least 3 months

- Have an archival tumour sample available or have a site of disease amenable to
biopsy and be willing to undergo a biopsy prior to the receipt of the assigned
study treatment

- Have adequate organ function

- Females must be non-pregnant and non-lactating, willing to use a highly effective
method of contraception from screening until study completion or be either
surgically sterile or post-menopausal

- Males must be surgically sterile, abstinent, or if engaged in sexual relations
with a woman of child-bearing potential, the participant and his partner must be
surgically sterile or using an acceptable, highly effective contraceptive method
from screening until study completion
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Prior treatment with HMBD-001, pertuzumab, or an agent that specifically targets HER3,
including pan-HER tyrosine kinase inhibitors

- Persistent clinically significant toxicities (Grade =2) from previous anti-cancer
therapy except for Grade >2 toxicities that are considered unlikely to put the
participant at an increased risk of treatment-related toxicity and/or impact the
study results e.g., alopecia

- Most recent anti-cancer therapy including radiotherapy at least 4 weeks, or
nitrosourea or mitomycin 3 at least 6 weeks, or 5 half-lives whichever is shorter
prior to starting the assigned study treatment

- Symptomatic primary Central Nervous System (CNS) cancer or metastases unless the
symptoms are stable for at least 28 days prior to the first dose of the study
drug and any symptoms have returned to baseline

- Evidence of abnormal cardiac function

- History of uncontrolled allergic reactions and/or known expected hypersensitivity
to the study drugs used in the treatment arm to which the participant is to be
enrolled into

- Any other known active malignancy except for treated cervical intraepithelial
neoplasia, or non-melanoma skin cancer

- Any uncontrolled illness or significant uncontrolled condition(s) requiring
systemic treatment

- Known Human Immunodeficiency Virus (HIV) infection

- Active hepatitis B or hepatitis C infection

- Pregnant or breast feeding

- COVID 19 infection within 3 months prior to the first dose of the study drug

- COVID 19 vaccination within 14 days prior to the first dose of the study drug
