Phase Ib of Copanlisib in Combination with Ibrutinib in Recurrent/Refractory Primary CNS Lymphoma (PCNSL)

BACKGROUND: PCNSL is an aggressive primary brain tumor with median progression free survival (PFS) after upfront methotrexate-based chemotherapy of 2-3 years. Outcome and treatment options are poor for recurrent/refractory (r/r) disease. This trial combines the pan-PI3K inhibitor copanlisib with Ibrutinib in patients with r/r PCNSL. METHODS: Eligible patients had r/r PCNSL, age≥18, ECOG≤2, normal end-organ function, and an unrestricted number of CNS directed prior therapies. Ibrutinib was given orally daily; copanlisib intravenously on days 1, 8, and 15 of each 28-day cycle. RESULTS: Six patients have been enrolled so far and received copanlisib at 60 mg and ibrutinib at 560 mg. Median age was 68 (range 50-77); 3 were women. Median ECOG was 1 (0: 2, 1: 3, 2: 1). All had recurrent parenchymal disease. Three had additional cerebrospinal fluid (CSF) involvement. Two had received prior single-agent ibrutinib. Initially, no prophylactic antimicrobial treatment was required. PCP prophylaxis was made mandatory after one patient developed PCP pneumonia leading to a grade 5 lung infection. Four patients are still on trial and one withdrew due to personal choice. Two grade 4 adverse events were observed in 2 patients (LFT elevation, lymphopenia); four grade 3 events in 3 patients (rash, lymphopenia, LFT elevation). The most common toxicities at any grade were transient, infusion-related hyperglycemia and hypertension. No Aspergillus infections have been observed. Enrollment into the next dose level (copanlisib 60 mg, ibrutinib 840 mg) is ongoing. After a median follow-up of 180 days (range 46-249), all patients were evaluated for response with an overall response rate of 67% with 1 CR, 3 PR, 1 SD and 1 PD as best response. CONCLUSION: Treatment with copanlisib and ibrutinib in patients with PCNSL has manageable adverse events after initiation of mandatory PCP prophylaxis. Clinical response was seen in 67% of patients.

7515 Background: PCNSL is an aggressive primary brain tumor with median progression free survival (PFS) after upfront methotrexate-based chemotherapy of 2-3 years. Outcome and treatment options are poor for recurrent/refractory (r/r) disease. Ibrutinib has shown promising clinical response in Mantle cell lymphoma, CLL, Marginal Zone, and Waldenström. This trial investigates Ibrutinib in patients with r/r PCNSL and SCNSL. Methods: Eligible patients had r/r PCNSL or SCNSL, age≥18, ECOG≤2, normal end-organ function, and unrestricted number of CNS directed prior therapies. In patients with SCNSL disease, systemic disease needed to be absent. Results: Twenty-five patients were enrolled (3 at 560 mg; 22 at 840 mg). Median age was 68 (range 21-85); 15 were women. Median ECOG was 1 (0: 2, 1: 15, 2: 8). 64% had PCNSL and 36% SCNSL; 68% had recurrent disease. Seventeen had parenchymal disease, 3 isolated cerebrospinal fluid (CSF) involvement and 5 both. Seven grade 4 adverse events were observed in 7 patients neutropenia (in 3 patients), lymphopenia (2), sepsis (1), and ALT elevation (1). Fourteen patients developed 20 grade 3 toxicities, including lymphopenia in 5 patients, hyperglycemia in 3, ALT elevation in 2, thrombocytopenia in 2, lung infection in 2, AST elevation in 1, neutropenia in 1, urinary tract infection in 1, colitis in 1, febrile neutropenia in 1 and fungal encephalitis in 1. The most common toxicities at any grade were hyperglycemia, thrombocytopenia and anemia of which most were grade 1/2. No grade 5 events have been observed. After a median follow-up of 414 days (range 289-674), 22/25 patients were evaluated for response (3 did not complete at least 15 days of drug treatment). Over all response was 68% (17/22; 77% (17/22) in patient that completed at least 15 days of drug treatment) with 10 CR, 7 PR, 2 SD and 3 PD as best response. The median PFS is 4.6 months (5.4 months in patients that completed at least 15 days of drug treatment; longest: 15.3 months). The median overall survival has not been reached. Conclusions: Patients with CNS lymphoma tolerate Ibrutinib with manageable adverse events. Clinical response was seen in 68% of CNS lymphoma patients. Clinical trial information: NCT02315326.

7533 Background: Primary CNS Lymphoma (PCNSL) is an aggressive primary brain tumor. Outcome and treatment options for patients with recurrent/refractory (r/r) disease are poor. We have observed promising efficacy of single agent ibrutinib in r/r PCNSL and secondary CNS lymphoma (SCNSL). In this phase 1B trial, we investigate the toxicity of ibrutinib in combination with high-dose methotrexate (HD-MTX) in r/r PCNSL/SCNSL. Methods: Eligible patients had r/r PCNSL/SCNSL or newly diagnosed SCNSL, age≥18, ECOG≤2, normal end-organ function, and with any number and type of prior therapies. In patients with SCNSL disease, systemic disease needed to be absent. HD-MTX was given at 3.5g/m2 every 2 weeks for a total of 8 doses. To minimize adverse events, ibrutinib was stopped on days of HD-MTX infusion and was restarted 5 days after MTX infusion or after completion of MTX-clearance, if clearance of MTX required more than 5 days. Ibrutinib was continued daily after completion of 8 doses of MTX. Results: Six patients have been enrolled; 3 received 560mg and 3 received 840mg ibrutinib in combination with HD-MTX. Median age was 62 (range 43-74); median ECOG 1 (0:2; 1:3; 2:1). Two had r/r PCNSL and 4 SCNSL. Three had brain disease, one isolated cerebrospinal fluid (CSF) involvement and two parenchymal and CSF involvement. Three patients had recurrent (2 PCNSL; 1 SCNSL), two refractory (both SCNSL), and one newly diagnosed disease (SCNSL). There were no grade 4 adverse events. Grade 3 events were observed in 5 patients (lymphopenia in 3, ALT elevation in 2, diarrhea in 1, electrolyte changes in 1, hypertension in 1). The most common adverse events were hypokalemia, low WBC, hyperglycemia, ALT and AST elevation. There was no dose reduction of methotrexate or ibrutinib in any patient. After a median follow-up of 130 days, all patients were evaluated for response after 4 doses of HD-MTX, with 4/6 (67%) showing a response: 2 CR, 2 PR, and 1 SD, 1 PD; both non-responders were refractory SCNSL. Ibrutinib concentrations were measured in plasma and CSF. Conclusions: Patients with CNS lymphoma tolerate the combination of HD-MTX and Ibrutinib (at 560 and 840mg) well. Continued enrollment into a combination arm that includes rituximab, methotrexate and ibrutinib is ongoing. Clinical trial information: NCT02315326.

6 Background: Patients (pts) with GC/GEC often present with A/M disease, which has a poor prognosis, with 1-year survival < 30%, and few treatment options. Nivolumab is a fully human anti-PD-1 IgG4 monoclonal antibody with a favorable safety profile and efficacy in melanoma, non–small-cell lung cancer, and renal cell carcinoma. The phase I/II, open-label CheckMate-032 study evaluated nivolumab ± ipilimumab in pts with solid tumors. Here, we report initial results for pts with GEC/GC receiving nivolumab monotherapy. Methods: Pts with A/M histologically confirmed GC/GEC, irrespective of PD-L1 status, were assigned to receive nivolumab alone (3 mg/kg IV Q2W) and treated until disease progression (PD) or intolerable toxicity. The primary endpoint was objective response rate (ORR); other endpoints included safety, progression-free survival, overall survival (OS), and biomarker status. Results: 59 pts were enrolled and treated with single-agent nivolumab. Median age was 60 y (range 29–80), and 83% of pts received ≥ 2 prior regimens. At database lock, 10 pts were on active treatment; 49 pts discontinued (PD, n = 40; unrelated adverse events, n = 4; treatment-related adverse events [TRAEs], n = 2; other, n = 3). Pts received a median of 4 doses (range 1–25). ORR was 12% (n = 7/58; 1 complete response, 6 partial responses); 12 pts (21%) had stable disease. Among responders, median duration of response was 7.1 mo (95% CI, 3.0–13.2). Median OS was 6.8 mo (95% CI, 3.3–12.4); 12-mo OS rate was 38% (95% CI, 23.2–52.7). 39% of tumor samples were PD-L1 positive ( ≥ 1% cutoff). ORRs in pts with PD-L1-positive and -negative tumors were 18% and 12%, respectively. TRAEs occurred in 66% of pts; most were Grade 1/2. Grade 3/4 TRAEs occurred in 14% of pts and included pneumonitis, fatigue, diarrhea, vomiting, hypothyroidism, and increased aspartate and alanine aminotransferase and alkaline phosphatase levels. No treatment-related deaths occurred. Conclusions: Nivolumab monotherapy was well tolerated and demonstrated encouraging antitumor activity in heavily pretreated pts with GC/GEC. Objective responses occurred in pts with PD-L1-positive and -negative tumors. Clinical trial information: NCT01928394.

Purpose In this phase II study (NCT00942747), temsirolimus was tested in patients with relapsed or refractory primary CNS lymphoma (PCNSL). Patients and Methods Immunocompetent adults with histologically confirmed PCNSL after experiencing high-dose methotrexate-based chemotherapy failure who were not eligible for or had experienced high-dose chemotherapy with autologous stem-cell transplant failure were included. The first cohort (n = 6) received 25 mg temsirolimus intravenously once per week. All consecutive patients received 75 mg intravenously once per week. Results Thirty-seven eligible patients (median age, 70 years) were included whose median time since their last treatment was 3.9 months (range, 0.1 to 14.6 months). Complete response was seen in five patients (13.5%), complete response unconfirmed in three (8%), and partial response in 12 (32.4%) for an overall response rate of 54%. Median progression-free survival was 2.1 months (95% CI, 1.1 to 3.0 months). The most frequent Common Toxicity Criteria ≥ 3° adverse event was hyperglycemia in 11 (29.7%) patients, thrombocytopenia in eight (21.6%), infection in seven (19%), anemia in four (10.8%), and rash in three (8.1%). Fourteen blood/CSF pairs were collected in nine patients (10 pairs in five patients in the 25-mg cohort and four pairs in four patients in the 75-mg cohort). The mean maximum blood concentration was 292 ng/mL for temsirolimus and 37.2 ng/mL for its metabolite sirolimus in the 25-mg cohort and 484 ng/mL and 91.1 ng/mL, respectively, in the 75-mg cohort. Temsirolimus CSF concentration was 2 ng/mL in one patient in the 75-mg cohort; in all others, no drug was found in their CSF. Conclusion Single-agent temsirolimus at a weekly dose of 75 mg was found to be active in relapsed/refractory patients with PCNSL; however, responses were usually short lived.

AbstractWith the exception of high-dose methotrexate (HD-MTX), there is currently no defined standard treatment for newly diagnosed primary central nervous system lymphoma (PCNSL). This review focused on first-line induction and consolidation treatment of PCNSL and aimed to determine the optimal combination of HD-MTX and the long-term beneficial consolidation methods. A comprehensive literature search of MEDLINE identified 1407 studies, among which 31 studies met the inclusion criteria. The meta-analysis was performed by using Stata SE version 15. Forest plots were generated to report combined outcomes like the complete response rate (CRR), overall survival, and progression-free survival. We also conducted univariate regression analyses of the baseline characteristics to identify the source of heterogeneity. Pooled analysis showed a CRR of 41% across all HD-MTX-based regimens, and three- and four-drug regimens had better CRRs than HD-MTX monotherapy. In all combinations based on HD-MTX, the HD-MTX + procarbazine + vincristine (MPV) regimen showed pooled CRRs of 63% and 58% with and without rituximab, respectively, followed by the rituximab + HD-MTX + temozolomide regimen, which showed a pooled CRR of 60%. Pooled PFS and OS showed that post-remission consolidation with autologous stem cell transplantation (ASCT) was associated with the best survival outcome, with a pooled 2-year OS of 80%, a 2-year PFS of 74%, a 5-year OS of 77%, and a 5-year PFS of 63%. Next, whole-brain radiation therapy (WBRT) + chemotherapy showed a pooled 2-year OS of 72%, 2-year PFS of 56%, 5-year OS of 55%, and 5-year PFS of 41%, with no detectable CR heterogeneity throughout the entire treatment process. In HD-MTX-based therapy of newly diagnosed PCNSL, MPV with or without rituximab can be chosen as the inductive regimen, and the rituximab + HD-MTX + temozolomide regimen is also a practical choice. Based on our study, high-dose chemotherapy supported by ASCT is an efficacious approach for consolidation. Consolidation with WBRT + chemotherapy can be another feasible approach.

11534 Background: KIT or PDGFRA oncogenic activation drives GIST progression throughout the disease course. Accordingly, currently approved agents in metastatic GIST focus on the therapeutic suppression of these receptors. However, the clinical benefit after imatinib (IM) progression is still modest, suggesting the co-operation of KIT/PDGFRA-independent mechanisms in GIST cell survival. Selinexor is an oral, selective inhibitor of XPO1-mediated nuclear export, and preclinical studies evidenced antitumoral activity in GIST as single agent and in combination with IM in both IM-sensitive and IM-resistant models. Methods: The phase Ib portion studied IM 400 mg daily plus weekly selinexor in patients (pts) with IM-resistant, advanced GIST. Prior intolerance to IM was not allowed. A standard 3+3 dosing schema was utilized to determine the recommended phase II dose (RP2D) of this combination. Investigator-assessed response was evaluated every 8 weeks using RECIST 1.1. Results: At data cutoff of Sep 25, 2020, 12 pts were enrolled and received treatment with IM 400 mg and selinexor once weekly at dose levels (DL) 1 (60 mg), DL2 (80 mg) and DL3 (100 mg). Median age 57 (range 46-77), 42% female, median prior therapies 4 (range 2-7). Although only 1/6 pts developed a dose limiting toxicity (DLT) at DL3, the RP2D was defined at DL2 (IM 400 mg daily and selinexor 80 mg once weekly) based on activity data in the DL2 and the need for dose reductions in 5/6 pts at DL3 after the DLT window. All pts were evaluable for toxicity and response. One DLT occurred at DL3 (G3 nausea). Non-DLT G3/4 toxicities were anemia (1/12 pts), neutropenia (1/12 pts), vomiting (1/12 pts) and fatigue (2/12 pts). Common G1/2 toxicities were nausea (11/12 pts), vomiting (10/12 pts), neutropenia (5/12 pts) and anemia, fatigue, diarrhea, and periorbital edema (4/12 pts each). No unexpected toxicities were observed. Overall response rate in the 12 pts evaluable for response was 67% (95% CI 0.349-0.901), with 2 pts achieving PR (17%) and 6 pts SD (50%) as the best response. Clinical benefit rate (CBR = CR, PR, SD) ≥ 16 weeks was 42% (95% CI 0.157-0.723). Median progression free survival was 3.5 months (95% CI 1.7-7.3). Four pts remain on trial at data cutoff. Conclusions: IM and selinexor combination is well-tolerated and has clinical activity in heavily pretreated GIST pts. The trial is currently exploring selinexor as single agent in the IM-resistant GIST population. Clinical trial information: NCT04138381.

PURPOSE: PV701, a replication-competent strain of Newcastle disease virus, causes regression of tumor xenografts after intravenous administration. This phase I study was designed to define the maximum-tolerated dose (MTD) and safety of single and multiple intravenous doses of PV701 as a single agent in patients with cancer. PATIENTS AND METHODS: Seventy-nine patients with advanced solid cancers that were unresponsive to standard therapy were enrolled. Four PV701 intravenous dosing regimens were evaluated: (1) single dose: one dose every 28 days; (2) repeat dose: three doses in 1 week every 28 days; (3) desensitizing: one lower dose followed by two higher doses in 1 week every 28 days; and (4) two week: one lower dose followed by five higher doses over 2 weeks every 21 days. RESULTS: A 100-fold dose intensification was achieved over 195 cycles. A first-dose MTD of 12 × 109 plaque-forming units (PFU)/m2 was established for outpatient dosing. After an initial dose of 12 × 109 PFU/m2, patients tolerated an MTD for subsequent doses of 120 × 109 PFU/m2. The most common adverse events were flu-like symptoms that occurred principally after the first dose and were decreased in number and severity with each subsequent dose. Tumor site–specific adverse events and acute dosing reactions were also observed but not cumulative toxicity. Objective responses occurred at higher dose levels, and progression-free survival ranged from 4 to 31 months. Tumor tissue from one patient was obtained after 11 months of therapy and showed evidence of PV701 particles budding from the tumor cell membrane by electron microscopy and a pronounced lymphoplasmacytic infiltrate by histologic examination. CONCLUSION: PV701 warrants further study as a novel therapeutic agent for cancer patients.

e16006 Background: FTD/TPI, an antimetabolite, is approved for treatment of refractory mGEC. This study sought to determine whether the combination of FTD/TPI with IRI (“TASIRI”) was safe and effective in mGEC previously treated with FP. Methods: This investigator‐initiated, multicenter, open‐label, single-dose level, single‐arm phase 1b study enrolled pts with mGEC previously treated with at least one line of FP containing regimen. FTD/TPI was given at 25 mg/m2 twice daily on days 1 to 5 with 180 mg/m2 IRI on day 1 of a 14‐day cycle. The primary endpoint was progression-free survival at six months (mo) (PFS-6). The aim was to show an improvement of PFS-6 from 15% to at least 30% based on historical controls. Results: At the time of data-cutoff (03Feb2021), 23 pts were screened and ultimately 20 pts were treated. The study met its primary endpoint. With a median follow-up of 9.8 mo (range 0.7 – 17), 8 pts are still on treatment and 4 pts have died. PFS-6 is 53.9% (lower limit of 95% CI: 28%). Median PFS and overall survival are 6.9 mo and not reached, respectively. At the time of data-cutoff, data were available for 13 pts with measurable disease by RECIST criteria and at least 1 on-treatment scan. Of those, 11 had stable disease and 2 had progressive disease as best response (5 pts had tumor shrinkage < 30%), therefore the disease control rate was 84.6%. The most common any grade (G) treatment related adverse events (TRAE) were nausea (n = 14, 70%), diarrhea (n = 9, 45%), and fatigue (n = 8, 40%). G3-4 TRAE in > 5% of pts were anemia (17%) and neutropenia (9%). 2 serious TRAE were reported: G4 febrile neutropenia (n = 1) and G3 hypotension (n = 1). There was no G5 TRAE. Conclusions: The combination of TASIRI showed encouraging clinical activity with a meaningful improvement in PFS-6 compared to historic controls. TASIRI was well tolerated and no new safety signals were seen. TASIRI warrants further investigation for patients with refractory mGEC and limited treatment options. Updated results with longer follow-up will be presented at the meeting. Clinical trial information: NCT04074343.

Population Based Study

ObjectiveReal-life studies on patients with primary CNS lymphoma (PCNSL) are scarce. Our objective was to analyze, in a nationwide population-based study, the current medical practice in the management of PCNSL.MethodsThe French oculo-cerebral lymphoma network (LOC) database prospectively records all newly diagnosed PCNSL cases from 32 French centers. Data of patients diagnosed between 2011 and 2016 were retrospectively analyzed.ResultsWe identified 1,002 immunocompetent patients (43% aged >70 years, median Karnofsky Performance Status [KPS] 60). First-line treatment was high-dose methotrexate-based chemotherapy in 92% of cases, with an increasing use of rituximab over time (66%). Patients <60 years of age received consolidation treatment in 77% of cases, consisting of whole-brain radiotherapy (WBRT) (54%) or high-dose chemotherapy with autologous stem cell transplantation (HCT-ASCT) (23%). Among patients >60 years of age, WBRT and HCT-ASCT consolidation were administered in only 9% and 2%, respectively. The complete response rate to initial chemotherapy was 50%. Median progression-free survival was 10.5 months. For relapse, second-line chemotherapy, HCT-ASCT, WBRT, and palliative care were offered to 55%, 17%, 10%, and 18% of patients, respectively. The median, 2-year, and 5-year overall survival was 25.3 months, 51%, and 38%, respectively (<60 years: not reached [NR], 70%, and 61%; >60 years: 15.4 months, 44%, and 28%). Age, KPS, sex, and response to induction CT were independent prognostic factors in multivariate analysis.ConclusionsOur study confirms the increasing proportion of elderly within the PCNSL population and shows comparable outcome in this population-based study with those reported by clinical trials, reflecting a notable application of recent PCNSL advances in treatment.

Gemcitabine Refractory

PurposeThe PI3K/Akt/mTOR pathway is activated in the majority of pancreatic cancers, and inhibition of this pathway has antitumor effects in preclinical studies. We performed a multi-institutional, single-arm, phase II study of RAD001(everolimus), an oral inhibitor of mTOR, in patients who experienced treatment failure on first-line therapy with gemcitabine.Patients and MethodsThirty-three patients with gemcitabine-refractory, metastatic pancreatic cancer were treated continuously with RAD001 at 10 mg daily. Prior treatment with fluorouracil in the perioperative setting was allowed. Patients were observed for toxicity, treatment response, and survival.ResultsTreatment with single-agent RAD001 was well-tolerated; the most common adverse events were mild hyperglycemia and thrombocytopenia. No patients were removed from the study because of drug-related adverse events. No complete or partial treatment responses were noted, and only seven patients (21%) had stable disease at the first restaging scans performed at 2 months. Median progression-free survival and overall survival were 1.8 months and 4.5 months, respectively. One patient (3%) had a biochemical response, defined as ≥ 50% reduction in serum CA19-9.ConclusionAlthough well-tolerated, RAD001 administered as a single-agent had minimal clinical activity in patients with gemcitabine-refractory, metastatic pancreatic cancer. Future studies in metastatic pancreatic cancer should assess the combination of mTOR inhibitors with other agents and/or examine inhibitors of other components of the PI3K/Akt/mTOR pathway.
