Non Hodgkin Lymphoma Clinical Trial
Copanlisib and Combination Chemotherapy for the Treatment of Relapsed or Refractory Diffuse Large B-Cell Lymphoma or Relapsed Grade 3b Follicular Lymphoma
This phase I trial studies the best dose of copanlisib when given together with combination chemotherapy (R-GCD) in treating patients with diffuse large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory) or grade 3b follicular lymphoma that has come back (relapsed) after 1 prior line of therapy. Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as gemcitabine, carboplatin, and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving copanlisib together with R-GCD as second line therapy may improve the complete response rate for patients with diffuse large B-cell lymphoma or follicular lymphoma.
OUTLINE: This is a dose-escalation study of copanlisib.
Patients receive copanlisib intravenously (IV) and gemcitabine IV on days 1 and 8, carboplatin IV and rituximab IV on day 1, and dexamethasone orally (PO) or IV 30-60 minutes prior to chemotherapy on day 1 or PO in the morning (AM) and 30-60 minutes prior to chemotherapy on days 2-4. Patients also receive pegfilgrastim subcutaneously (SC) on day 8 or 9. Treatment repeats every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed for up to 1 year.
Subjects must meet one of the following criteria:
Histologically confirmed relapsed/refractory DLBCL or grade 3b follicular lymphoma.
Follicular lymphoma that has relapsed within 2 years of primary therapy that included an anti-CD20 antibody in combination with chemotherapy as measured from the date of the last dose of chemotherapy
Eastern Cooperative Oncology Group (ECOG) performance status =< 2
Previous exposure to other PI3K inhibitors (except copanlisib) is acceptable provided there is no resistance (resistance defined as no response [response defined as partial response (PR) or CR] at any time during therapy), or progressive disease (PD) after any response (PR/CR) or after stable disease within 6 months from the end of the therapy with a PI3K inhibitor

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 safety follow-up visit
