Arms and Interventions

|---|---|
| Experimental: Copanlisib in combination with Ibrutinib Participants will be assigned to the following dose levels: Dose level 1: Ibrutinib 560 mg daily + Copanlisib 60 mg weekly (3w on/1w off) Dose level 2: Ibrutinib 840 mg daily + Copanlisib 60 mg weekly (3w on/1w off) Dose level -1: Ibrutinib 560 mg daily + Copanlisib 45 mg weekly (3w on/1w off). Phase II: (Simon two-stage design: 14 patients will be treated at the MTD (including 6 patients from the phaseIb portion) If at least 11 patients respond then an additional 19 patients will be accrued to the second stage. Patients in the phase II portion of the trial will receive sequential drug dosing. Patient will be treated in 28-day cycles. During one cycle, only one drug will be administered with a ibrutinib/copanlisib ratio of 1:2. Patients will receive Ibrutinib at 840 mg daily during cycle 1 (day 1 through day 28) (28-day cycles), then copanlisib 60mg weekly on day 1, 8, and 15 during cycle 2 and 3. Patients will then repeat the sequence. |

Outcome Measures
Primary Outcome Measures
- maximum tolerated dose (MTD) (phase Ib) [1 year]
The "3+3" design will be applied in the phase Ib portion of the trial.
- overall response rate (ORR) (phase II) [1 year]
To explore the therapeutic efficacy measured by overall response rate (ORR) of Copanlisib in combination with Ibrutinib in patients with refractory/relapsed PCNSL or newly diagnosed PCNSL not able to tolerate standard chemotherapy (phase II)This study will use the modified International Primary CNS Lymphoma Collaborative Group (IPCG)12.
Secondary Outcome Measures
- adverse events in terms of incidence and severity (phase Ib and II) [2 years]
adverse events at each visit with the NCI CTCAE v4.03 used as a guide for the grading of severity.
- progression free survival (PFS) (phase II) [2 years]
Progression-free survival (PFS) is defined as the time from the date of treatment start to the date of the first documented PD or death due to any cause.
- duration of response (DOR) (phase II) [2 years]
Duration of response is defined as the time from the date of first occurrence of CR or PR to the date of the first documented PD or death due to any cause.
- overall survival (OS) (phase II) [2 years]
Overall survival time (OS) is defined as the time from treatment start to the date of death due to any cause.
- To evaluate cerebral spinal fluid (CSF) pharmacokinetics of Copanlisib and Ibrutinib and correlate with plasma pharmacokinetics (phase Ib) [2 years]
Eligibility Criteria
Criteria
Inclusion Criteria:
Patients eligible for inclusion in this study must meet ALL the following criteria:
-
Men and woman who are at least 18 years of age on the day of consenting to the study.
-
Histologically documented PCNSL
-
Relapsed/refractory PCNSL or newly diagnosed PCNSL patients who are deemed medically ineligible by the treating investigator (phase II only) to receive standard first-line chemotherapy. All recurrent/refractory patients need to have received at least one prior CNS directed therapy. There is no restriction on the number of recurrences.
-
For recurrent/refractory patients, parenchymal lesions must have unequivocal evidence of disease progression on imaging (MRI of the brain or head CT) 21 days of study registration. For patients with leptomeningeal disease only, CSF cytology must document lymphoma cells and/or imaging findings consistent with CSF disease 21 days of study registration (at the discretion of the investigator).
-
ECOG performance status ≤ 2.
-
Life expectancy of > 3 months (in the opinion of the investigator).
-
Adequate bone marrow and organ function shown by:
-
Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L
-

-
Hemoglobin (Hgb) ≥ 8 g/dL and no red blood cell (RBC) transfusion within the past 14 days prior to study registration
-
International Normalized Ratio (INR) ≤ 1.5 and PTT (aPTT) ≤ 1.5 times the upper limit of normal
-
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 times the upper limit of normal
-
Serum bilirubin ≤ 1.5 times the upper limit of normal; or total bilirubin ≤ 3 times the upper limit of normal with direct bilirubin within the normal range in patients with well documented Gilbert Syndrome
-
Serum creatinine ≤ 2 times the upper limit of normal
-
Creatinine clearance ≥ 30 mL/min
-
Lipase ≤ 1.5 x upper limit of normal
-
Women of childbearing potential (WOCBP) and men must agree to use effective contraception when sexually active. This applies for the time period between signing of the informed consent form and 30 days (for WOCBP) and 90 days (for men) after the last administration of study treatment. A woman is considered of childbearing potential, i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include but are not limited to hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for continuous 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy.
-
The investigator or a designated associate is requested to advise the patient how to achieve highly effective birth control (failure rate of less than 1%), e.g. intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner and sexual abstinence
-
The use of condoms by male patients is required unless the female partner is permanently sterile. Female subjects of childbearing potential must have a negative plasma pregnancy test upon study entry
