Abstract Leptomeningeal disease (LMD) is an increasingly common complication from solid tumor malignancies with a poor prognosis and limited treatment options. We conducted a single arm Phase II study of combined ipilimumab and nivolumab in patients with LMD from solid tumor malignancies (NCT02939300). Patients received manufacturer-specific dosing regimens of combined ipilimumab and nivolumab based on primary-tumor histology until definitive progression or unacceptable toxicity. The primary end point was rate of overall survival at 3 months (OS3). A Simon two-stage design was used to compare a null hypothesis OS3 of 18% against an alternative of 44%. Eighteen patients with diverse primary tumor histologies were enrolled and all received at least one dose of combined ipilimumab and nivolumab. Median follow up based on patients still alive was 8.0 months (range: 0.5 to 15.9 months). The study met its primary endpoint as 8 of 18 (OS3 0.44; 90% CI: 0.24 to 0.66) patients were alive at three months after enrollment. One third of patients experienced one (or more) grade-3 or higher adverse events possibly related to treatment. Two patients discontinued protocol treatment due to unacceptable toxicity (hepatitis and colitis, respectively). The most frequent adverse events overall included fatigue (N=7), nausea (N=6), fever (N=6), anorexia (N=6) and rash (N=6). Combined ipilimumab and nivolumab has an acceptable safety profile and demonstrates promising activity in LMD patients; this therapeutic approach should be studied in larger, multicenter clinical trials to validate these results as well as better identify patients who will benefit.

AbstractLeptomeningeal disease (LMD) is a common complication from solid tumor malignancies with a poor prognosis and limited treatment options. We present a single arm Phase II study of 18 patients with LMD receiving combined ipilimumab and nivolumab until progression or unacceptable toxicity (NCT02939300). The primary end point is overall survival at 3 months (OS3). Secondary end points include toxicity, cumulative time-to-progression at 3 months, and progression-free survival. A Simon two-stage design is used to compare a null hypothesis OS3 of 18% against an alternative of 44%. Median follow up based on patients still alive is 8.0 months (range: 0.5 to 15.9 months). The study has met its primary endpoint as 8 of 18 (OS3 0.44; 90% CI: 0.24 to 0.66) patients are alive at three months. One third of patients have experienced one (or more) grade-3 or higher adverse events. Two patients have discontinued protocol treatment due to unacceptable toxicity (hepatitis and colitis, respectively). The most frequent adverse events include fatigue (N = 7), nausea (N = 6), fever (N = 6), anorexia (N = 6) and rash (N = 6). Combined ipilimumab and nivolumab has an acceptable safety profile and demonstrates promising activity in LMD patients. Larger, multicenter clinical trials are needed to validate these results.

216 Background: Perioperative treatments have significantly improved survival in patients with resectable gastric cancer, increasing 5-year overall survival from 23% with surgery alone to 45% with FLOT, Although FLOT has been recognized as the first choice for neoadjuvant chemotherapy in gastric or GEJ adenocarcinoma, its efficacy needs to be improved. Sintilimab, a fully human IgG4 monoclonal antibody that binds to programmed cell death receptor-1 (PD-1), has shown remarkable clinical efficacy in various cancers. We aimed to assess the activity and safety profile of the combination of FLOT and sintilimab for neoadjuvant treatment of gastric or GEJ adenocarcinoma. Methods: In this ongoing, single-arm, phase II study, we recruited patients from Henan Cancer Hospital in China with histopathologically diagnosed resectable gastric or GEJ adenocarcinoma who had clinical T3/N+ or higher stage. Patients were given 4 cycles of FLOT (docetaxel 50 mg/m2, oxaliplatin 80 mg/m2, leucovorin 200 mg/m2, fluorouracil 2600 mg/m2, 24-h infusion on day 1, q2w) in combination with 3 cycles of sintilimab (200mg, iv, d1, q3w), followed by D2 surgery and 4 postoperative cycles of FLOT. The primary endpoint was pathological complete response (pCR). The secondary endpoints included major pathological remission (MPR) and R0 resection rate and adverse events . Results: A total of 20 patients were enrolled in the study between Aug 10 2019 and Sep 15 2020. One patient refused surgery, one person's disease progressed. Two patients have not yet completed neoadjuvant treatment . 16 pts who experienced D2 resection, 10 (62.5%) achieved major pathologic response (MPR), including 3 (18.8%) with a pathologic complete response (pCR) in primary tumor. The R0 resection rate was up to 93.8%, The grade 3 or 4 treatment-related adverse events (TRAE) included lymphopenia(25%), anaemia (20%),fatigue (20%),leucopenia (15%), neutropenia (5%), diarrhea(5%), Alanine aminotransferase increased(5%),There was no surgical delays or unexpected surgical complications related to drug toxicity. Conclusions: Neoadjuvant combination of sintilimab and FOLT is a safe and efficacious treatment option for patients with gastric or GEJ adenocarcinoma, 18.8% pCR rate and 62.5%MPR rate is encouraging. Our clinical study is still enrolling, and the survival effects are under follow up. Clinical trial information: NCT04341857.

Purpose Patients with relapsed or refractory chronic lymphocytic leukemia (CLL) have profound immune defects and limited treatment options. Given the dramatic activity of lenalidomide in other B-cell malignancies and its pleotropic immunomodulatory effects, we conducted a phase II trial of this agent in CLL. Patients and Methods Patients with relapsed or refractory B-cell CLL (B-CLL) were eligible if they required treatment as per the National Cancer Institute Working Group 1996 guidelines. Lenalidomide was administered orally at 25 mg on days 1 through 21 of a 28-day cycle. Response was assessed after each cycle. Patients were to continue treatment until disease progression, unacceptable toxicity, or complete remission. Rituximab was added to lenalidomide on disease progression. Results Forty-five patients were enrolled, with a median age of 64 years. Sixty-four percent of the patients had Rai stage III or IV disease, and 51% were refractory to fludarabine. The overall response rate was 47%, with 9% of the patients attaining a complete remission. Fatigue, thrombocytopenia, and neutropenia were the most common adverse effects noted in 83%, 78%, and 78% of the patients, respectively. Conclusion Lenalidomide is clinically active in patients with relapsed or refractory B-CLL. These findings are encouraging and warrant further investigation of this agent in the treatment of this disorder.

Purpose This phase II study evaluated the activity of combined treatment with interferon alfa-2b and sorafenib, a Raf and multiple receptor tyrosine kinase inhibitor, in patients with advanced renal carcinoma. Patients and Methods Eligible patients had metastatic or unresectable renal carcinoma with a clear-cell component, no prior systemic therapy, performance status 0 to 1, and measurable disease. Treatment consisted of interferon alfa-2b 10 × 106 U subcutaneously three times weekly and sorafenib 400 mg orally bid. The primary end point was confirmed Response Evaluation Criteria in Solid Tumors response rate. Results Twelve (19%) of 62 assessable patients achieved an objective confirmed response. An additional 31 (50%) had an unconfirmed partial response or stable disease as best response. The median progression-free survival was 7 months (95% CI, 4 to 11 months). The most common adverse events were fatigue, anorexia, anemia, diarrhea, nausea, rigors/chills, leukopenia, fever, and transaminase elevation. Von Hippel-Lindau gene mutations were detected in four (22%) of 18 archival tumor specimens. Conclusion The confirmed response rate for the combination of sorafenib and interferon in advanced renal carcinoma is greater than expected with either interferon or sorafenib alone. The toxicity of this combination is dominated by adverse events common to interferon that limit further development of this regimen.

Purpose To evaluate the efficacy of maintenance sunitinib after chemotherapy for small-cell lung cancer (SCLC). Patients and Methods The Cancer and Leukemia Group B 30504 trial was a randomized, placebo-controlled, phase II study that enrolled patients before chemotherapy (cisplatin 80 mg/m2 or carboplatin area under the curve of 5 on day 1 plus etoposide 100 mg/m2 per day on days 1 to 3 every 21 days for four to six cycles). Patients without progression were randomly assigned 1:1 to placebo or sunitinib 37.5 mg per day until progression. Cross-over after progression was allowed. The primary end point was progression-free survival (PFS) from random assignment for maintenance placebo versus sunitinib using a one-sided log-rank test with α = .15; 80 randomly assigned patients provided 89% power to detect a hazard ratio (HR) of 1.67. Results One hundred forty-four patients were enrolled; 138 patients received chemotherapy. Ninety-five patients were randomly assigned; 10 patients did not receive maintenance therapy (five on each arm). Eighty-five patients received maintenance therapy (placebo, n = 41; sunitinib, n = 44). Grade 3 adverse events with more than 5% incidence were fatigue (19%), decreased neutrophils (14%), decreased leukocytes (7%), and decreased platelets (7%) for sunitinib and fatigue (10%) for placebo; grade 4 adverse events were GI hemorrhage (n = 1) and pancreatitis, hypocalcemia, and elevated lipase (n = 1; all in same patient) for sunitinib and thrombocytopenia (n = 1) and hypernatremia (n = 1) for placebo. Median PFS on maintenance was 2.1 months for placebo and 3.7 months for sunitinib (HR, 1.62; 70% CI, 1.27 to 2.08; 95% CI, 1.02 to 2.60; one-sided P = .02). Median overall survival from random assignment was 6.9 months for placebo and 9.0 months for sunitinib (HR, 1.28; 95% CI, 0.79 to 2.10; one-sided P = .16). Three sunitinib and no placebo patients achieved complete response during maintenance. Ten (77%) of 13 patients evaluable after cross-over had stable disease on sunitinib (6 to 27 weeks). Conclusion Maintenance sunitinib was safe and improved PFS in extensive-stage SCLC.

Abstract Abstract 1731 Panabinostat is a very potent panhistone deacetylase inhibitor (HDACi) with activity in acute myelogenous leukemia (CCR 2006;12: 4628). We hypothesized that single agent panabinostat could be active in patients with low and intermediate-1 risk MDS. Oral route of administration and safety profile further increased interest in this approach. To test this concept we designed a phase II study of panabinostat for patients above 18 years of age with lower risk disease. Patients could have received prior therapy or be treatment naïve. Appropriate renal, hepatic and cardiac functions were required. Patients were excluded if they had previous HDACi treatment. Patients with history of cardiac pathology such as rhythm alterations were excluded from the study. Use of drugs that could induce QT prolongation and CYP3A4 inhibitors were not allowed. Panabinostat was used at dose of 20 mg orally three times a week for consecutive 3 weeks with cycles repeated every 4 weeks. The primary objective of the study was overall response rate defined by IWG. A maximum of 40 patients could be enrolled. The study was to stop early if the expected response rate was less than 15%. Stopping rules were as follows: Stop if the number of patients with hematologic improvement/the number of patients evaluated was 0/15 or 1/32. The study also contained a stopping rule for non-hematological toxicity. Thirteen patients were enrolled between August 2009 and December 2010. Median age was 70 years (range 47 to 84, 84% of patients older than 60), 70% were transfusion dependent, 70% had intermediate-1 risk MDS, most patients were diploid but one patient with del(5q), one with trisomy 8, one with complex cytogenetics and 2 with deletion of 20q were included. Median percent of marrow blasts was 1% (range 1 to 6%). At start of therapy, median hemoglobin was 9.5 (range 7.5–11.2 G/dL), median platelet count was 56 (range 6–431 k/uL) and median white blood cell count was 4.6 (range 0.8–20.3 k/uL). Approximately 40% had previous therapy for MDS including hypomethylating agents, lenalidomide and investigational agent. Median number of prior therapies for treated patients was 2 (range 1 to 4). Median duration of disease at time of enrollment was 10 months (range 1–50). Patients received a median of 4 cycles of panabinostat (range 1–9). Of 13 patients, 1(8%) achieved a hematological improvement including both an erythroid and platelet response that lasted for 3 months. No complete remissions or partial responses were documented. Six patients (46%) had stable disease for a median duration of 6 months (range 2–13.6). Median overall survival was 15 months (1–31 months). Two patients died because progression to AML. Therapy was well tolerated: no major adverse events were documented except for one patient that developed significant QTc prolongation. Adverse events included mild fatigue and gastrointestinal toxicity. As a biomarker of molecular activity, histone H3 acetylation was measured in 5 patients with variable results. Induction of acetylation was documented in 2. Despite the fact that the stopping rule for activity was not officially met, because of the very modest clinical activity observed, the study was closed to new patient entry. In conclusion, panabinostat given as a single agent orally at a dose of 20 mg thee times a week for 3 weeks followed by one week of rest has limited clinical activity in patients with lower risk MDS. Disclosures: No relevant conflicts of interest to declare.

15025 Background: We report here results of phase II study for a combination therapy with paclitaxel/doxifluridine to treat advanced/recurrent gastric cancer showing resistance to S-1. S-1 is an oral fluoropyrimidine drug that combines tegafur, CDHP, and oxonic acid (Oxo), which has been most frequently used in Japan. Methods: Subject registration was started to employ 35 patients with advanced/recurrent gastric cancer, who were selected among those with measurable lesions fitting to RECIST, and with resistant to S-1 treatment (PS, 0–2; and patient’s ages ranged from over 20 to under 75 years). We employed dosages that Hyodo et. al. used in phase I study and recommended as a standard regimen including paclitaxel, 80 mg/m2, i.v. on days 1 and 8; and doxifluridine, 600 mg/m2, p.o. on days 1–14.. These were repeated every 3 weeks. Primary endpoint of present phase II study was: RR; and secondary endpoints were OS, PFS, and onset rate of adverse events. Results: From September, 2003 to March, 2005, 35 patients were registered: including 28 men; 7 women; median age of 66 years (range, 49–75 years); and PS levels were, zero with 21 and one with 14 patients. In 33 eligible patients, except 2, clinical usefulness was evaluated resulting in response rate of 18.2% (PR, 6; SD, 15; PD, 10; and NE, 2 patients). OS was 321 days, and PFS was 119 days. Severe adverse events were found in 3 patients to discontinue the present treatment though; other adverse events were relatively mild without no death due to the present therapy. Conclusions: Patients in the present study with advanced/recurrent gastric cancer were those resistant to S-1 treatment. Response rate was 18.2% increasing to 63.6% when SD was added. OS resulted in relatively long period of 321 days, while OS from initial time starting S-1 treatment was 619 days. This suggests that the present treatment is useful as the sequential therapy. Adverse events were controllable suggesting a high reliability of the present therapy. In conclusion, the present therapy with paclitaxel/doxifluridine could be a treatment of choice as an useful second line chemotherapy for patients undergone S-1 treatment.
