Summary

This trial is testing a new drug called CYT-0851 in patients with certain types of cancer that have not responded to other treatments. The goal is to see if the drug is safe and understand how it works in the body.

Who is the study for?
Adults with certain B-cell malignancies or advanced solid tumors who understand the study and consent to participate. They must have a specific type of tumor, measurable disease, be in good physical condition (ECOG 0-1), and agree to use contraception if necessary. Excluded are those unable to swallow pills, recent heart attack or stroke victims, uncontrolled hypertension sufferers, individuals with active CNS metastases or significant health issues that could affect safety.
What is being tested?
The trial is testing CYT-0851 alone and combined with other chemotherapy drugs like rituximab and bendamustine or gemcitabine in patients with relapsed/refractory B-cell malignancies and advanced solid tumors. The goal is to determine safe dosages for Phase 2 trials.
What are the potential side effects?
Potential side effects may include typical reactions associated with chemotherapy such as nausea, fatigue, risk of infection due to lowered white blood cell counts, possible organ inflammation from drug interactions, and any unique adverse events related to CYT-0851 which will be closely monitored.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Chronic Lymphocytic Leukemia (CLL) include Bruton tyrosine kinase (BTK) inhibitors (e.g., ibrutinib, acalabrutinib), BCL2 inhibitors (e.g., venetoclax), and monoclonal antibodies (e.g., rituximab, obinutuzumab). BTK inhibitors block the BTK enzyme, which is crucial for B-cell receptor signaling, thereby inhibiting the growth and survival of CLL cells. BCL2 inhibitors promote apoptosis in CLL cells by targeting the BCL2 protein, which prevents programmed cell death. Monoclonal antibodies bind to specific antigens on the surface of CLL cells, marking them for destruction by the immune system. These targeted therapies are significant for CLL patients as they offer more precise treatment options with potentially fewer side effects compared to traditional chemotherapy, improving both efficacy and quality of life.
