A Phase I Study of PI3Ká,ä Inhibitor Copanlisib in Combination with PD-1 Antagonist Nivolumab in Patients with Transformed Chronic Lymphocytic Leukemia (Richter s Transformation) or Non-Hodgkin Lymphoma
This phase I trial studies the best dose and how well copanlisib when given together with
nivolumab works in treating patients with Richter's transformation or transformed indolent
non-Hodgkin lymphoma. Copanlisib may stop the growth of tumor cells by blocking some of the
enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab,
may help the body's immune system attack the cancer, and may interfere with the ability of
tumor cells to grow and spread. Giving copanlisib and nivolumab may work better in treating
patients with Richter's transformation or transformed non-Hodgkin lymphoma.
- Diagnosis of Richter syndrome (RS; transformed CLL), or indolent NHL (follicular
lymphoma [FL], lymphoplasmacytic lymphoma [LPL], marginal zone lymphoma [MZL]) in
transformation. Only patients who have diffuse large B-cell lymphoma (DLBCL) histology
are eligible in transformation are eligible (for example, patients with transformation
into Hodgkin lymphoma subtype are not eligible).
- Participants with RS must have received at least 2 cycles of prior systemic therapy
for either RS or underlying CLL.
- Participants with FL and other indolent lymphomas in transformation must have
underwent >= 1 prior chemo-immunotherapy regimen (e.g.,
rituximab/cyclophosphamide/doxorubicin/prednisone/vincristine [R-CHOP] or similar)
administered for >= 2 cycles and have had either documented disease progression to the
most recent treatment regimen, or refractory disease and must not be candidates for or
planning to pursue autologous stem cell transplant, or must have relapsed following
autologous stem cell transplant which took place at least 3 months prior to study
- Radiographically measurable lymphadenopathy (>= 1.5 cm) or measurable extra-nodal
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2.
- Total bilirubin =< 2 x institutional upper limit of normal (ULN).
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) less than 2.5 x
- Estimated creatinine clearance (CrCL) using the Cockroft-Gault equation >= 30 mL/min.
- Platelets >= 75,000/mm^3 (>= 25,000/mm^3 if due to disease involvement in the bone
marrow; transfusion is not permitted to achieve this level).
- Absolute neutrophil count >= 1000/mm^3 (>= 500/mm^3 if due to disease involvement in
the bone marrow).
- Female participants who:
- Are postmenopausal for at least 1 year before the screening visit, OR
- Are surgically sterile (i.e. tubal ligation), OR
- Participants of childbearing potential must have a negative serum beta-human
chorionic gonadotropin at screening and:
- Agree to practice 1 highly effective method and 1 additional effective
(barrier) method of contraception at the same time, from the time of signing
the informed consent through 1 month after the last dose of copanlisib, or 5
months after the last dose of nivolumab, whichever is later, or
- Agree to practice true abstinence, when this is in line with the preferred
and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar,
ovulation, symptothermal, post-ovulation methods] withdrawal, spermicides
only, and lactational amenorrhea are not acceptable methods of
contraception. Female and male condoms should not be used together.).
- Male patients, even if surgically sterilized (i.e., status post-vasectomy) must:
- Agree to practice effective barrier contraception during the entire study
treatment period and through 1 month after the last dose of copanlisib, OR
- Agree to practice true abstinence, when this is in line with the preferred and
usual lifestyle of the subject (Periodic abstinence [e.g., calendar, ovulation,
symptothermal, post-ovulation methods for the female partner] withdrawal,
spermicides only, and lactational amenorrhea are not acceptable methods of
contraception. Female and male condoms should not be used together.).
- Ability to understand and the willingness to sign a written informed consent document.
- History of allogeneic bone marrow or organ transplant.
- Prior therapeutic intervention with any of the following:
- Therapeutic anti-cancer antibodies within 2 weeks.
- Radio- or toxin-immunoconjugates within 10 weeks.
- Radiation therapy within 2 weeks.
- All other chemotherapy within 3 weeks prior to initiation of study therapy.
- Targeted therapy - within 6 half-lives (for example, 36 hours for ibrutinib).
- History of prior malignancy except:
- Malignancy treated with curative intent and no known active disease present for
>= 2 years prior to initiation of therapy on current study.
- Adequately treated non-melanoma skin cancer or lentigo maligna (melanoma in situ)
without evidence of disease.
- Adequately treated in situ carcinomas (e.g., cervical, esophageal, etc.) without
evidence of disease.
- Asymptomatic prostate cancer managed with "watch and wait" strategy.
- Any adverse event related to prior therapy that has not recovered to =< grade 1
(excluding grade 2 alopecia and grade 2 neuropathy).
- Chronic use of corticosteroids in doses which exceed 15 mg of prednisone per day, or
- Uncontrolled immune hemolysis or thrombocytopenia.
- A history of human immunodeficiency virus (HIV) infection. HIV-positive participants
on combination antiretroviral therapy are ineligible because of the potential for
pharmacokinetic interactions with copanlisib and/or nivolumab. In addition, these
participants are at increased risk of lethal infections when treated with
marrow-suppressive therapy. Appropriate studies will be undertaken in participants
receiving combination antiretroviral therapy when indicated.
- Major surgery (under general anesthesia) within 30 days prior to therapy.
- Evidence of active hepatitis B virus (HBV) or hepatitis C virus (HCV), or history of

diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders
(such as vitiligo, psoriasis) not requiring systemic treatment, well controlled asthma
and/or mild allergic rhinitis (seasonal allergies) are eligible.

- Females who are pregnant or nursing. Pregnant individuals are excluded from this study
because copanlisib and nivolumab have the potential to cause fetal harm based on
relevant animal studies (Refer to the appropriate prescribing information). Because
there is an unknown but potential risk for adverse events in nursing infants,
breast-/chest-feeding should be discontinued prior to treatment with copanlisib and
