New antibody drug shows promise for Hard-to-Treat cancers
NCT ID NCT06345482
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new drug called MHB039A, a bispecific antibody, in 196 people with advanced solid tumors that have not responded to standard treatments. The goal is to see if the drug is safe and effective. Participants receive the drug and are monitored for side effects and tumor response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MHB039A (a bispecific antibody)
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
- What could go wrong
- This is an early-phase trial (Phase I/II) with a small number of participants, so the drug may not prove effective or safe. Side effects and dose-limiting toxicities are being closely monitored.

Inclusion Criteria: * Histologically or cytologically documented advanced or metastatic solid tumor that is refractory/relapsed to standard therapies, or for which no effective standard therapy is available, or the subject refuses standard therapy. * Written and signed informed consent * Aged 18 years or older * Eastern Cooperative Oncology Group (ECOG) Performance Score of 0 or 1 * Life expectancy \>=3 months Exclusion Criteria: * Prior malignancy active within the previous 5 years except for the tumor for which a subject is enrolled in the study, and locally curable cancers that have been apparently cured, (e.g. basal cell skin cancer, or carcinoma in situ of the cervix or others) * Receiving any chemotherapy within 3 weeks prior to the first dose;or other systemic anticancer therapy within 4 weeks prior to the first dose * Receiving prior anti-PD-1, anti-PD-L1, anti-CTLA(cytotoxic T-lymphocyte-associated protein)-4 or any other immunotherapy or immune-oncology (IO) agent within 28 days of first dose with MHB039A or experienced a toxicity that led to permanent discontinuation of prior immunotherapy * Unresolved toxicities from prior anticancer therapy
