New drug JBZ-001 enters first human trial for Hard-to-Treat cancers
NCT ID NCT06801002
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial is testing a new oral drug called JBZ-001 in 25 adults with advanced solid tumors or certain blood cancers (like lymphoma) that have not responded to standard treatments. The drug works by blocking a protein cancer cells need to grow. The main goals are to check safety, find the best dose, and see if the drug shows any signs of shrinking tumors. Because this is the first time JBZ-001 is being tested in humans, the focus is on safety and dosing, not yet on proving it works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- JBZ-001 (a drug that blocks a protein called DHODH, which cancer cells need to grow)
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced cancers that have not responded to other therapies.
- What could go wrong
- This is a very early, first-in-human trial with only 25 participants, so the drug may not be effective or could have unexpected side effects. Success in this small study does not guarantee broader benefits.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Participant must be ≥18 years of age, at the time of signing the informed consent. 2. Dose escalation and expansion: 1. Solid tumors: have a histologically confirmed relapsed or refractory advanced solid tumor for which no standard approved treatment is available, or is ineligible for, or did not tolerate standard approved treatment. 2. NHL: have a histologically confirmed relapsed or refractory diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) or Mantle cell lymphoma (MCL) for which no standard approved treatment is available, or is ineligible for, or did not tolerate standard approved treatment. 3. Measurable/evaluable disease or documented relapse, respectively, relevant for tumor type as follows: 1. Solid tumors: per Response evaluation criteria in solid tumors (RECIST) 1.1 with at least one target lesion 2. NHL: Measurable disease defined as ≥1 measurable nodal lesion (long axis \>1.5 cm and short axis \>1.0 cm) or ≥1 measurable extra-nodal lesion (long axis \>1.0 cm) on computed tomography (CT) scan or magnetic resonance imaging (MRI) 4. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2. 5. All previous anti-cancer therapy-related AEs should have resolved to grade 1 or baseline value with the exception of alopecia and stable, treated endocrine toxicities of immune checkpoint inhibitors (ICIs) Note: Subjects with irreversible toxicity that in the opinion of the treating physician is not reasonably expected to be exacerbated by the investigational product may be included (e.g., hearing loss, hormone deficiency requiring replacement therapy) - Exclusion Criteria: 1. Known hypersensitivity to JBZ-001 or any of its excipients 2. Corrected interval between Q and T wave on ECG (QTc) ≥ 470 msec using Fredericia's formula. 3. Has significant and symptomatic cardiovascular disease (such as congestive heart failure New York Heart Association class III or higher, myocardial infarction, cerebrovascular disease, unstable angina, unstable arrhythmia) within the 3 months prior to first dose of JBZ-001. 4. Has another malignant disease requiring treatment, with the exception of curatively treated malignancies or malignancies with very low potential for recurrence or progression. 5. For solid tumor subjects: 1. Symptomatic ascites or pleural effusion. A subject who is clinically stable for 2 weeks following treatment for these conditions (including therapeutic thoraco- or paracentesis) is eligible. 2. Known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are clinically stable for at least 2 weeks prior to study entry, as long as the dose is ≤ 4 mg of dexamethasone or equivalent per day 6. Known active HIV infection on antiretroviral therapy. Note: Testing is not required for eligibility. 7. Known active infection with hepatitis B or hepatitis C. Note: Testing is not required for eligibility. 8. Any other active infection requiring systemic therapy. 9. Major surgery (excluding procedures to stabilize the vertebrae) within 4 weeks or minor surgery within 2 weeks prior to first dose of JBZ-001. 10. Has a history of GI surgery or other procedures that might interfere with the absorption or swallowing of the study drug. 11. History or clinical evidence of any medical condition which the investigator judges as likely to interfere with the results of the study, poses an additional risk in participating, or makes the subject unlikely to comply with the study-related visits and assessments. 12. Female participants: pregnant or breastfeeding.
