Brief Summary:
This trial studies how well bendamustine and rituximab in combination with copanlisib work in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma. Drugs used in chemotherapy, such as bendamustine and rituximab, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Copanlisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving bendamustine and rituximab with copanlisib may work better than bendamustine and rituximab alone in treating chronic lymphocytic leukemia or small lymphocytic lymphoma.

Detailed Description:

This is a dose de-escalation study of copanlisib.

Patients receive copanlisib intravenously (IV) over 1 hour on days 1, 8, and 15 or days 1 and 15 (depending on dose level). Patients also receive rituximab IV on day 1 and bendamustine IV on days 1 and 2 of cycles 1-4. Patients who achieve at least a partial response (MRD-positive) continue on treatment for 2 additional cycles. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Beginning cycle 7, patients receive copanlisib IV over 1 hour on days 1 and 15 for an additional 6 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 14 days, then periodically for up to 3 years.

Previous corticosteroid therapy must be stopped or reduced to the allowed dose at least 7 days performing the screening computed tomography (CT)/magnetic resonance imaging (MRI). If a patient is on chronic corticosteroid therapy, corticosteroids should be de-escalated to the maximum allowed dose before the screening. Patients may be using topical or inhaled corticosteroids
  • Use of CYP3A4 inhibitors and inducers. Copanlisib is primarily metabolized by CYP3A4. Therefore, concomitant use of strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, indinavir, nelfinavir and saquinavir), and strong inducers of CYP3A4 (e.g., rifampin, phenytoin, carbamazepine, phenobarbital, St. John's wort) are not permitted from day -14 of cycle 1 until the end of treatment visit
