Summary

This trial is testing a combination of two drugs, vemurafenib and obinutuzumab, to treat hairy cell leukemia (HCL) that has not been treated before. The trial will have 28 patients total, and will test the efficacy of the combination treatment. If the treatment is successful, bone marrow aspirate and biopsy will be performed to assess response and evaluate minimal residual disease (MRD).

Who is the study for?
Adults with previously untreated classical Hairy Cell Leukemia who meet specific blood count criteria and are in good physical condition. They must have normal organ function, agree to use contraception, and not be pregnant. Excluded are those with hepatitis B or C, HIV, other cancers needing treatment that could interact with the trial drugs, uncontrolled infections, or a history of liver disease.
What is being tested?
The trial is testing an oral drug called Vemurafenib combined with Obinutuzumab infusions against Hairy Cell Leukemia. Initially, 9 patients will receive this combination to see if it's effective; if successful, another 19 will join. The treatment spans over four cycles (16 weeks), followed by bone marrow tests for response evaluation.
What are the potential side effects?
Possible side effects include skin rash or lesions due to Vemurafenib and infusion-related reactions from Obinutuzumab such as fever or chills. Liver enzymes might increase indicating potential liver issues; heart rhythm problems could also occur.
