619 Background: There is a strong rationale for investigating MET and PD-L1 inhibition in metastatic papillary renal cancer (PRC). We previously reported response rates (RR) and progression free survival (PFS) for savolitinib (MET inhibitor) and durvalumab (PD-L1 inhibitor) together. Here we report overall survival (OS) data available 12 months after the last patient was enrolled. Methods: This single arm phase I/II trial explores durvalumab (1500mg Q4W) and savolitinib (600mg OD) together in PRC, with a 4wk savolitinib run in. Treatment naïve or previously treated patients with metastatic PRC were included. Confirmed RR (RECIST v1.1), PFS, tolerability (CTCAE v4.03) and overall survival (OS) were analysed. MET and PD-L1 biomarkers were explored (NCT02819596). Results: 42 patients were enrolled with 41 receiving at least one dose of study treatment. Safety and efficacy analyses were performed on these 41 patients. The median follow up was 14.3 months. IMDC good, intermediate and poor risk disease occurred in 29%, 63%, and 7% of patients respectively. Overall confirmed RR was 27% while median PFS was 4.9 months (95% CI: 2.5 – 12.0 months). Median OS was 12.3 months (95% CI: 5.8 – 21.3 months). Confirmed RR and median OS in the previously untreated cohort (N=27) were 33% and 12.3 months (95% CI: 4.7 – not reached (NR) months) respectively. Treatment related Grade 3/4 toxicity occurred in 34% of patients. No new safety signals were seen. PD-L1 and MET expression were not associated with higher RR (25% and 40% respectively) or longer OS. Conclusions: The combination of savolitinib and durvalumab has clinical activity in PRC and outcomes were not enhanced in biomarker positive cancers. Clinical trial information: NCT02819596.

e20647 Background: PD-1/PD-L1 inhibitors show clinical activity in non-small cell lung carcinoma (NSCLC). However, these agents are sometimes associated with potentially fatal immune related pneumonitis. Preliminary reports of trials suggest a difference in the rate of pneumonitis associated with PD-1 and PD-L1 inhibitors. In this meta-analysis, we sought to determine the overall incidence of pneumonitis, and differences by type of inhibitor and prior chemotherapy use. Methods:We systematically searched databases (PubMed-Medline, Embase, Scopus) and conference proceedings until December 2016 for clinical trials using PD-1/PD-L1 inhibitors. Rates of pneumonitis of any grade and grade 3 or higher from all phase I-III trials investigating nivolumab, pembrolizumab, atezolimumab, durvalumab and avelumab for NSCLC were collected. Only single agent PD-1/PDL-1 inhibitor trials were included. The incidence of pneumonitis across trials was calculated using DerSimonian-Laird random effects models. We compared incidences between PD-1 and PD-L1 inhibitors, as well as between treatment naïve and previously treated patients (pts). Results: 19 distinct published trials (12 with PD-1 inhibitors [n = 3232] and 7 with PD-L1 inhibitors [n = 1806]) were identified. PD-1 inhibitors were found to have statistically significant higher incidence of any grade pneumonitis as compared to PD-L1 inhibitors (3.6%, 95%CI 2.4%-4.9% vs 1.3%, 95%CI 0.8%-1.9%; p = 0.001). There was also a higher incidence of grade 3 or greater pneumonitis with PD-1 inhibitors (1.1%, 95%CI 0.6%-1.7% vs 0.4%, 95%CI 0%-0.8%, p = 0.02). Pts who received PD-1 or PD-L1 inhibitors in the front line setting experienced more grade 1-4 pneumonitis as compared to previously treated pts (4.3%, 95%CI 2.4%-6.3% vs 2.8%, 95%CI 1.7%- 4%, p = 0.03, however the rates of grade 3 or greater pneumonitis were not significantly different in treatment naïve and previously treated pts. Conclusions: Pneumonitis was more frequently associated with use of PD-1 inhibitors than PD-L1 inhibitors. There was a higher incidence of all grade pneumonitis with PD-1 inhibitors in treatment naïve patients as compared to previously treated patients.

Abstract Background: SGI-110 is a second generation HMA formulated as a dinucleotide of decitabine (DAC) and deoxyguanosine delivered as a small volume SC injection that yields longer half-life and more extended DAC exposure than DAC IV infusion. A phase 1 clinical trial of SGI-110 demonstrated a differentiated pharmacokinetic profile from DAC IV, potent hypomethylation, and clinical responses in previously treated patients with MDS and AML (Kantarjian et al. 2012). Phase 1 established 60 mg/m2 QDx5 as the biologically effective dose (BED), and 90 mg/m2QDx5 as the Maximum tolerated dose (MTD) in MDS patients given in 28-day cycles. Phase 2 is conducted to evaluate dose response between the BED and MTD in MDS patients. Methods: Int, or HR MDS, and CMML patients who were either treatment-naïve or previously treated were randomized to either 60 mg/m2 or 90 mg/m2QDx5 every 28 days. Efficacy was evaluated by the clinical responses of CR, PR, marrow CR (mCR), and Hematological Improvement (HI) based on the International Working Group Criteria 2006 as well as transfusion-independence. Adverse events (AEs) as graded by the CTCAE v4 criteria and pharmacodynamic biological activity as measured by Long Interspersed Nucleotide Element LINE-1 (an index of global DNA methylation) were also assessed. Patients are being followed for overall survival. Results: The study completed target enrolment with 102 patients: 53 who were refractory or have relapsed on prior treatment, and 49 previously untreated. Fifty three patients were randomized to 60 mg/m2 and 49 patients to 90 mg/m2 QDx5 with a median follow up of 8.2 months (range 1-21). Most baseline patient characteristics were well balanced between the 2 treatment arms with no significant differences in median age (71.7 vs. 72.5 y); male gender (70 vs. 61%); ECOG PS 2 (15 vs. 12%); HR MDS (28 vs. 37%); transfusion-dependence (57 vs. 55%), median baseline Hb (9.25 vs. 9.3 g/dL); platelets count (42.5 vs. 45 x109/L), and neutrophils count (1.19 vs. 1.16 x109/L) for the 60 and 90 mg/m2 QDx5 respectively. However, there were 15 CMML patients (28%) randomized to 60 mg/m2 vs. only 7 CMML patients (14%) randomized to 90 mg/m2(p=0.097). All but 2 patients in the previously treated group received one or more HMA. At the time of the data cutoff, 38 of 102 patients (37%) were still on treatment. Median number of treatment cycles was 4 for previously treated patients, and 5 for the treatment naïve group (range 1-22 cycles). CR+mCR were observed in 10/53 (19%), and 11/49 (22%) in the 60 and 90 mg/m2 arms respectively (p=0.8). CR was observed in 7/49 treatment naïve patients (14%) while CR+mCR were observed in 11/53 previously treated patients (21%) with no significant differences between 60 and 90 mg/m2 arms. Transfusion independence for at least 8 weeks was reported in 32% and 24% for platelets and RBCs respectively with no difference between the 2 treatment arms. Treatment naïve patients benefited from higher rate of transfusion-independence (58% and 46% for platelets and RBCs respectively). Potent demethylation was achieved in both treatment arms with a mean LINE-1 DNA demethylation of 27.3 and 30.5% for 60 and 90 mg/m2 respectively (p=0.12). Overall incidence of Grade ≥3 AEs regardless of relationship to treatment was reported in 81 vs. 88% for 60 and 90 mg/m2 treatment arms respectively (p=0.42).There was a slightly higher but non-significant difference in Grade ≥3 thrombocytopenia (51 vs 38%) and pneumonia (20 vs. 13%) for the 90 mg/m2 arm compared to 60 mg/m2. Early 8-week any-cause mortality occurred in 3/102 patients treated (3%), 2 at 60 and 1 at 90 mg/m2. Follow up for survival is still ongoing. Conclusions: SC SGI-110 is a well-tolerated novel HMA with biological and clinical activity in the treatment of Int and HR MDS, and CMML patients with particularly promising activity in patients previously treated with azacitidine or decitabine. Clinical responses, transfusion independence, DNA demethylation as assessed by LINE-1, and Safety did not significantly differ between the 2 treatment doses.

Abstract Bcl-2 is an anti-apoptotic protein closely linked to chemotherapy resistance and inferior survival in patients (pts) with CLL. Genasense(GNS) enhances apoptosis induced by fludarabine (F), dexamethasone, and rituximab (R) in vitro, and has limited single-agent activity in heavily pre-treated CLL pts. Down-regulation of Bcl-2 may further sensitize CLL cells to apoptosis induced by F and R without exposing subjects to the toxicity of alkylating agents. CLL and NHL pts occasionally exhibit a “cytokine release syndrome” (spiking fever, back pain, and occasional hypotension) with GNS treatment. We hypothesized that a “step dosing” approach with GNS, similar to that sometimes used for R, could ameliorate these effects and allow safe and effective combination of this agent with F and R. We are currently evaluating this combination in pts with either previously untreated (UT) or relapsed, previously treated (PT) CLL who require systemic treatment. Eligibility includes: plts ≥ 50,000/mm3; serum Cr ≤ 1.5 mg/dL; adequate organ function; negative Coombs; no history of autoimmune hemolytic anemia. In cycle 1, GNS is given by continuous intravenous infusion at 1.5 mg/kg/d days 1 to 7. R is given on a dose-escalating schema (day 4, 125 mg/m2; day 6, 250 mg/m2). F (25 mg/m2/d) is given on days 6 to 8. In subsequent 28-day cycles (up to 6), the dose of GNS is escalated to 3 mg/kg/d days 1 to7 days, with R 375 mg/m2 on day 5 and F days 5 to7. To date, 20 pts have been enrolled (17 PT and 3 UT). Characteristics included: median age, 62 yrs (range 39 to 82 yrs); Rai stage III (2 pts) and IV (6 pts). Prior to administration of either F or R, single-agent GNS treatment at the initial reduced dose in Cycle 1 resulted in a median decrease in lymphocytes of 15% (among all patients regardless of decline in lymphocyte count) (Baseline: 48.3 cells x 103/ml; day 4: 40.1 cells x 103/ml). For the 13 pts who experienced a decline in lymphocyte count in cycle 1 prior to F and R, the median percentage change was 17%, with 4 pts having a > 25% decrease. Three PT pts discontinued from study treatment prior to completing 6 cycles, 2 due to disease progression, and 1 with Grade 3 thrombocytopenia that was unresolved after 4 weeks. Among the 20 pts treated to date (9 ongoing), the most common grade 3 or higher adverse events have been neutropenia, pyrexia and thrombocytopenia. Serious adverse events have been noted in only 6 of 20 pts (all PT pts) and have included 2 pts with fever (1 neutropenic), 2 R infusion reactions, 1 lymph node abscess and 1 tumor lysis syndrome (with sepsis). Conclusions: 20 pts have been treated with combination GNS, F and R. Single-agent activity with GNS has been observed at a reduced dose of 1.5 mg/kg/d in cycle 1. The “step dosing” approach appears to be a well-tolerated, alternative approach to the administration of GNS. Further details of safety and efficacy will be presented.

Abstract Background: Ibrutinib (ibr), a first-in-class, once-daily Bruton's tyrosine kinase inhibitor, is approved by the US FDA for treatment of patients (pts) with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) including pts with del17p. The phase 1b/2 PCYC-1102 trial showed single-agent efficacy and tolerability in treatment-naïve (TN; O'Brien, Lancet Oncol 2014) and relapsed/refractory (R/R) CLL/SLL (Byrd, N Engl J Med 2013). We report efficacy and safety results of the longest follow-up to date for ibr-treated pts. Methods: Pts received 420 or 840 mg ibr QD until disease progression (PD) or unacceptable toxicity. Overall response rate (ORR) including partial response (PR) with lymphocytosis (PR-L) was assessed using updated iwCLL criteria. Responses were assessed by risk groups: unmutated IGVH, complex karyotype (CK; ≥3 unrelated chromosomal abnormalities by stimulated cytogenetics assessed by a reference lab), and in hierarchical order for del17p, then del11q. In the long-term extension study PCYC-1103, grade ≥3 adverse events (AEs), serious AEs, and AEs requiring dose reduction or discontinuation were collected. Results: Median age of the 132 pts with CLL/SLL (31 TN, 101 R/R) was 68 y (range, 37-84) with 43% ≥70 y. Baseline CK was observed in 41/112 (37%) of pts. Among R/R pts, 34 (34%) had del17p, 35 (35%) del11q, and 79 (78%) unmutated IGVH. R/R pts had a median of 4 prior therapies (range, 1-12). Median time on study was 46 m (range, 0-67) for all-treated pts, 60 m (range, 0-67.4) for TN pts, and 39 m (range, 0-67) for R/R pts. The ORR (per investigator) was 86% (complete response [CR], 14%) for all-treated pts (TN: 84% [CR, 29%], R/R: 86% [CR, 10%]). Median progression-free survival (PFS) was not reached (NR) for TN and 52 m for R/R pts with 60 m estimated PFS rates of 92% and 43%, respectively (Figure 1). In R/R pts, median PFS was 55 m (95% confidence intervals [CI], 31-not estimable [NE]) for pts with del11q, 26 m (95% CI,18-37) for pts with del17p, and NR (95% CI, 40-NE) for pts without del17p, del11q, trisomy 12, or del13q. Median PFS was 33 m (95% CI, 22-NE) and NR for pts with and without CK, and 43 m (95% CI, 32-NE) and 63 m (95% CI, 7-NE) for pts with unmutated and mutated IGVH, respectively(Figure 2). Among R/R pts, median PFS was 63 m (95% CI, 37-NE) for pts with 1-2 prior regimens (n=27, 3 pts with 1 prior therapy) and 59 m (95% CI, 22-NE) and 39 m (95% CI, 26-NE) for pts with 3 and ≥4 prior regimens, respectively. Median duration of response was NR for TN pts and 45 m for R/R pts. Pts estimated to be alive at 60 m were: TN, 92%; all R/R, 57%; R/R del17p, 32%; R/R del 11q, 61%; R/R unmutated IGVH, 55%. Among all treated pts, onset of grade ≥3 treatment-emergent AEs was highest in the first year and decreased during subsequent years. With about 5 years of follow-up, the most frequent grade ≥3 AEs were hypertension (26%), pneumonia (22%), neutropenia (17%), and atrial fibrillation (9%). Study treatment was discontinued due to AEs in 27 pts (20%) and disease progression in 34 pts (26%). Of all treated pts, 38% remain on ibr treatment on study including 65% of TN pts and 30% of R/R pts. Conclusions: Single-agent ibrutinib continues to show durable responses in pts with TN or R/R CLL/SLL including those with del17p, del11q, or unmutated IGVH. With extended treatment, CRs were observed in 29% of TN and 10% of R/R pts, having evolved over time. Ibrutinib provided better PFS outcomes if administered earlier in therapy than in the third-line or beyond. Those without CK experienced more favorable PFS and OS than those with CK. Ibrutinib was well tolerated with the onset of AEs decreasing over time, allowing for extended dosing for 65% of TN and 30% of R/R pts who continue treatment.

7718 Background: Gemcitabine and irinotecan has been shown to have an antitumor activity as a single agent against previously treated SCLC. The objective of this study was to assess the efficacy and safety of gemcitabine combined with irinotecan in patients with refractory or relapsed SCLC. Methods: Patients with histologically or cytologically confirmed SCLC, 20 to 74 years in age, performance status 0–2, with a history of receiving one platinum-based chemotherapy were eligible for the study. Treatment consisted of gemcitabine (1,000 mg/m2) and irinotecan (150 mg/m2) on days 1 and 15 of a 28-day cycle.The primary endpoint was the response rate (RR), and planned sample size for this phase II study was 30 patients (Simon's two-stage minimax design). Results: Thirty-one patients were enrolled and 30 patients (24 males/6 females, 10 refractory/20 sensitive, median age, 65 years) receive protocol treatment in this phase II trial. The median treatment cycles were 3 (1–10). The overall response rates was obtained in 39.3% (95% CI: 18.1% to 60.5%) of the patients, including two patients with refractory disease and 9 patients with sensitive disease. The median overall survival time was 14.4 months, and the 1-year survival rate was 51%. The median survival time of the patients with refractory disease was 7.4 months, compared with 14.4 months for patients with sensitive disease. The chief grade 3/4 toxicities included neutropenia (42%), thrombocytopenia (3%), diarrhea (9%), and liver dysfunction (3%). The only grade 4 toxicities were one case of grade 4 neutropenia (3.3%) and one case of grade 4 thrombocytopenia (3.3%). Conclusion: Gemcitabine plus irinotecan is an active regimen that seems to be well- tolerated by patients with previously treated SCLC. No significant financial relationships to disclose.

9055 Background: LungMAP is a National Clinical Trials Network umbrella trial for previously-treated SqNSCLC. S1400D is a phase II biomarker-driven therapeutic sub-study evaluating the FGFR inhibitor AZD4547 in patients (pts) with FGFR positive chemo-refractory SqNSCLC. Methods: Eligible pts had tumor FGFR alteration and/or mutation by next generation sequencing (Foundation Medicine), measurable disease, Zubrod PS 0-2, progression after 1 line of systemic therapy, and adequate end organ function. Receipt of prior immunotherapy was allowed. Eligible pts received AZD4547 80 mg bid orally. Primary endpoint was overall response rate (ORR) by RECIST; secondary endpoints included progression-free survival (PFS) and duration of response (DoR). Originally designed as a randomized trial of AZD4547 versus docetaxel, it was redesigned to be a single arm AZD4547 trial with the emergence of immunotherapy as standard 2ndline therapy. Forty pts were required to rule out an ORR of < = 15% if the true ORR was > 35% (90% power, alpha 0.05). Results: 93 pts (13% of pts screened on S1400) were assigned to S1400D; 43 were enrolled with 28 receiving AZD4547. Pt characteristics: median age 66.3 y (49-88), female (n = 8, 29%), & Caucasian (n = 25; 89%). Biomarker profile: FGFR1 amplification (n = 38; 86%); FGFR3 S249C (n = 4; 9%); FGFR3 amplification (n = 3; 7%); and FGFR3 fusion (n = 2; 5%). Nine pts (26%) had more than one biomarker alteration. The study was closed at interim analysis for futility in October 2016. Treatment related Grade 3 AEs were seen in 5 pts (dyspnea, fatigue, hyponatremia, lung infection & retinopathy); 1 pt had Grade 4 sepsis. There were no Grade 5 AEs. Median follow up among alive pts was 4.3 months (mos). Of 25 response evaluable pts, one with FGFR3 S249C had unconfirmed PR (4%, 95% CI 1-20%) with DoR of 1.5 mos. Median PFS was 2.7 mos (95% CI 1.4 - 4.3 mos). Conclusions: This is the first Phase II trial to evaluate AZD4547 as a targeted approach in pts with previously treated FGFR-altered SqNSCLC. AZD4547 had an acceptable safety profile but minimal activity in this biomarker-enriched cohort. Evaluation of other targeted agents in LUNG-MAP is currently ongoing. Clinical trial information: NCT02965378.

79 Background: ModraDoc006 is a novel formulation of docetaxel and to enhance bioavailability, this tablet is co-administered with ritonavir (r), an inhibitor of cytochrome p450 3A4 and P-glycoprotein. The safety, anti-tumor activity and pharmacokinetics (PK) of ModraDoc006/r were investigated by dose-escalation in patients with mCRPC, to propose a recommended phase 2 dose (RP2D). Methods: Progressive mCRPC patients, who were treatment naïve or previously treated with either abiraterone or enzalutamide, received a maximum of 30 weekly cycles of ModraDoc006/r in a bi-daily once weekly (BIDW) schedule. Plasma docetaxel concentrations were determined at the first 2 cycles up to 48h after intake of ModraDoc006/r. Adverse events were evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Serum Prostate Specific Antigen (PSA) levels were assessed every 6 weeks. Results: 23 patients were included, of whom 20 were evaluable for safety and PK. In 5 patients, the initial 30-20/100-100 dose was explored, with observation of one dose limiting toxicity (DLT) (grade 3 alanine aminotransferase increase). The next dose level of 30-20/200-200 resulted in 2 DLTs in 6 patients (grade 3 diarrhea and mucositis). Subsequently, two intermediate dose levels: 30-20/200-100 and 20-20/200-100 were explored in 6 and 3 patients. At the 30-20/200-100 dose, an adequate docetaxel exposure was achieved and 1 DLT (grade 3 diarrhea) was observed, with no DLTs at the 20-20/200-100 dose. Common treatment-related AEs (occurring in > 30% of all patients) were diarrhea, nausea, vomiting, anorexia and fatigue. Five patients completed the maximum of 30 weekly treatments. In 10 patients, evaluable for anti-tumor activity after treatment with ≥9 cycles, 4 confirmed and 2 non-confirmed PSA responses ( > 50% decrease) were observed. Conclusions: The RP2D of BIDW ModraDoc006/r in mCRPC was established as 30-20/200-100 mg. These results are encouraging for further development of ModraDoc006/r as a convenient, safe and effective alternative to IV docetaxel for mCRPC patients. A phase 2b study is currently being conducted. Clinical trial information: NCT03136640.

ObjectiveThe aim of this study was to assess the safety and efficacy of extending bevacizumab therapy beyond 15 months in nonprogressive ovarian cancer.Patients and MethodsIn this multinational prospective single-arm study (ClinicalTrials.gov NCT01239732), eligible patients had International Federation of Gynecology and Obstetrics stage IIB to IV or grade 3 stage I to IIA ovarian cancer without clinical signs or symptoms of gastrointestinal obstruction or history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within the preceding 6 months. Prior neoadjuvant chemotherapy was permitted. After debulking surgery, patients received bevacizumab 15 (or 7.5) mg/kg every 3 weeks (q3w) with 4 to 8 cycles of paclitaxel (investigator’s choice of 175 mg/m2 q3w or 80 mg/m2 weekly) plus carboplatin AUC 5 to 6 q3w. Single-agent bevacizumab was continued until progression or for up to 24 months. The primary end point was safety.ResultsBetween December 2010 and May 2012, 1021 patients from 35 countries began study treatment. Bevacizumab was administered at 15 mg/kg in 89% of patients and for more than 15 months in 53%. Median follow-up duration was 32 months (range, 1–50 months). The most common all-grade adverse events were hypertension (55% of patients), neutropenia (49%), and alopecia (43%). The most common grade 3 or higher-grade adverse events were neutropenia (27%) and hypertension (25%). Bevacizumab was discontinued because of proteinuria in 5% of patients and hypertension in 3%. Median progression-free survival (PFS) was 25.5 months (95% confidence interval, 23.7–27.6 months).ConclusionExtended bevacizumab demonstrated increased incidences of proteinuria and hypertension compared with 12 or 15 months of bevacizumab in previous trials, but these rarely led to bevacizumab discontinuation. Median PFS is the longest reported for frontline bevacizumab-containing therapy. The longer bevacizumab duration beyond 15 months in this study may improve PFS without substantially compromising safety.
