New drug doses tested for rare blood cancer
NCT ID NCT05978739
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This phase 2 trial tested two different daily doses of the drug orelabrutinib in 40 people with mantle cell lymphoma, a rare blood cancer. The goal was to see which dose works better at shrinking tumors and controlling the disease. Participants included both newly diagnosed and relapsed patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Orelabrutinib
- What this could lead to
- If successful, this could help determine the best dose of orelabrutinib to control mantle cell lymphoma with fewer side effects.
- What could go wrong
- This is a small, early-phase trial with only 40 participants. Results may not apply to all patients, and the drug may not work as well as hoped or could cause unexpected side effects.

Inclusion Criteria: 1. Male and female subjects ≥ 18 years of age. 2. Mantle cell lymphoma (MCL) confirmed by histopathology. 3. Subjects who have not previously received standard systemic care and relapsing/refractory subjects who have previously received standard systemic care. 4. At least one measurable lesion. 5. ECOG Physical fitness score 0-2 points. 6. Expected survival time ≥ 4 months. 7. Full hematology function. 8. Blood clotting function is basically normal. 9. Subjects with basically normal liver, kidney and heart function. 10. Subject voluntarily signs a written ICF. 11. The serum pregnancy test of female subjects with fertility potential was negative within 7 days before the first dosing. 12. Female subjects with reproductive potential or male subjects and their partners must agree to use effective contraception for at least 6 months from signing the ICF until the last dose of the study drug. Exclusion Criteria: 1. Adequate treatment with BTK inhibitors. 2. Have a history of severe allergic disease and a history of severe drug allergy. 3. Subjects who have received the treatment or drug restricted in the protocol within the time specified for the first use of the investigational drug. 4. The last use of a potent CYP3A inhibitor or potent CYP3A inducer (including food, western medicine, and Chinese medicine) was less than 2 weeks (or less than 5 half-lives, depending on the time) from the first trial, or plan to take a potent CYP3A inhibitor or potent CYP3A inducer drug or food during the study period. 5. History of other active malignant diseases within 2 years prior to screening. 6. Subjects with systemic bacterial, viral, fungal (other than nail fungal infections) or parasitic infections with poorly controlled activity. 7. Indicates active hepatitis B or C virus infection. 8. There are diseases that are excluded from the criteria in the programme. 9. Toxicity of previous anticancer therapy was still ≥ grade 2 at the start of study therapy (according to CTCAE V5.0). 10. History of severe bleeding disorder. 11. People with a known history of alcohol or drug abuse. 12. Subjects with mental disorders or poor compliance. 13. Pregnant or lactating female subjects. 14.
