e18046 Background: Platinum and non-platinum doublet chemotherapy has similar efficacy in advanced NSCLC patients (pts). Bevacizumab (B) improves outcomes when added to platinum doublets, but its safety and efficacy in combination with non-platinum doublets is unknown. This study was designed to test the combination of B, docetaxel (D), and gemcitabine (G) in first-line treatment of advanced NSCLC. Methods: Pts with metastatic, non-squamous NSCLC, PS 0-1, and measurable disease by RECIST were enrolled in this open-label, single arm phase II trial. Pts received D (75 mg/m2) on d1, G (900 mg/m2) on d1 & 8, and B (15 mg/kg) on d1 every 21d for up to 6 cycles, followed by B maintenance until progression or 12 mos total. Pts received growth factor d9. CT scans were performed every 6 wks. The primary endpoint was 1-yr progression-free survival (PFS), with secondary endpoints of safety, objective response rate (ORR), overall PFS, and overall survival (OS). Pts with tumor cavitation, untreated brain metastases, and hemoptysis were excluded. Planned enrollment was 46. Results: 13 pts were enrolled from 12/2009 to 4/2011. Pt characteristics: Median age 63 (35-69), 85% male, PS 0 (38%), PS 1 (62%). The median # of cycles of chemotherapy was 6 (1-6), median # cycles of B was 4 (1-15), with 2 pts coming off study prior to the first evaluation (1 grade 5 encephalopathy, 1 grade 4 febrile neutropenia). 5 pts (38%) had chemo dose reduction and 4 (31%) discontinued treatment for toxicity. 3 pts (23%) discontinued B prior to progression, 2 for tumor cavitation and 1 for grade 1 hemoptysis. The grade 3-5 non-hematologic toxicity rate was 69%, with 6 pts (46%) hospitalized with pneumonitis/pneumonia felt possibly related to study drugs. At this point enrollment was halted for safety concerns. The 1-yr PFS was 8%, and the median PFS was 6.9 mos (95% CI 2.0-NYR). 11 pts were evaluable for response, and 6 pts had partial responses for an ORR of 55%. The median OS was NYR with median follow up of 10.9 mos. Conclusions: The combination of B, D, and G was not tolerable at the doses and schedule used in this study. A formal phase I trial is needed if this combination is to be investigated further.

Gastroesophageal Junction Cancer

BackgroundIrinotecan is used as second-line treatment in advanced gastric or gastroesophageal junction (G/GEJ) cancer. The role of anti-programmed death-1 (PD-1) antibody plus irinotecan, in this setting and population is unclear.MethodsThis multicenter, open-label, single-arm, phase II trial was conducted in 11 Chinese hospitals. Eligible patients had histologically confirmed advanced G/GEJ cancer that refractory to, or intolerant of, first-line chemotherapy with a platinum and/or fluoropyrimidine. Subjects received HX008 200 mg intravenously every 3 weeks plus irinotecan 160 mg/m2 intravenously every 2 weeks until disease progression or unacceptable toxicity. The primary end point was objective response rate (ORR) as assessed according to Response Evaluation Criteria In Solid Tumors V.1.1.ResultsBetween October 2018 and September 2019, a total of 58 patients with advanced G/GEJ cancer were enrolled in this study. Median follow-up was 10.5 months (range 7.4–18.9) months. Confirmed ORR was observed in 16 patients, for an ORR of 27.6% (95% CI 16.1% to 39.1%); 19 patients experienced stable disease, leading to a disease control rate of 60.3% (95% CI 46.4% to 73.0%). ORR in patients with PD-ligand 1 (L1) positive (Combined Positive Score (CPS) ≥1) and negative (CPS＜1) tumors was 38.5% (5/13) and 37.5% (3/8), respectively. Median duration of response was 8.0 months (range 1.5–12.5), 6 of 16 (37.5%) responses were ongoing. Median progression-free survival (PFS) was 4.2 months (95% CI 2.2 to 5.5). Median overall survival (OS) was not reached (NR) (95% CI 8.7 to NR). Patients with PD-L1 positive tumors tended to have longer OS than those with PD-L1 negative tumors, but the difference was not statistically significant (NR vs 8.7 months, p=0.1858).The most common treatment-related adverse events of grade 3 or 4 included neutropenia (32.8%), leukopenia (31.0%), anemia (17.2%), decreased appetite (8.6%), vomit (6.9%), nausea (6.9%) and fatigue (5.2%). There were no treatment-related deaths.ConclusionThe combination of HX008 and irinotecan demonstrated promising activity and manageable safety as second-line treatment in patients with advanced G/GEJ cancer, which warrants further study.Trial registration numberNCT03704246

Immunosuppressive Tumor Microenvironment

Abstract INTRODUCTION High-grade meningiomas are associated with significant neuro-cognitive morbidity and a poor prognosis. Systemic therapies, to date, have demonstrated minimal efficacy. We recently found that high-grade meningiomas harbor an immunosuppressive tumor microenvironment and that programmed cell death-ligand 1 (PD-L1) expression may contribute to the aggressive phenotype of these tumors. Therefore, we conducted a single-arm, open-label phase II trial evaluating efficacy of pembrolizumab, a PD-1 inhibitor, in a cohort of 24 patients with recurrent and progressive grade II and III meningiomas. METHODS The primary endpoint was the rate of progression-free survival at 6 months. The trial distinguished between 6-month PFS (PFS-6) rates of 26% vs. 52%. If at least 10 patients demonstrated a 6-month PFS, among the 24 patients, the agent would be considered worthy of further study. This design has at least 88% power using an exact binomial test with a one-sided significance level of 0.1. RESULTS Between November 2017 to December 2019, twenty-four patients were enrolled. The majority of the patients in our cohort were heavily pre-treated; prior to enrolling to the study, twenty patients underwent more than one surgical resection and twelve patients had received more than one round of radiotherapy. Our study met its primary endpoint and achieved a 6-month progression-free survival rate of 0.50 (90% exact CI: 0.32-0.68) and a median PFS of 8.3 months (90% CI: 4.1-12.9 months). For the twelve patients who achieved the PFS-6 primary endpoint, median PFS from the start of treatment was 17.3 months (90% CI: 9.7 – 24.3 months). Four patients had grade-3 or higher adverse events that were at least possibly treatment-related, including colitis, skin infection, encephalopathy and transaminitis. CONCLUSION Our study achieved its primary endpoint. These results suggest that pembrolizumab exerts promising activity on these tumors and results in prolonged PFS compared to historical controls.

Purpose We performed a phase II study of oral vorinostat, a histone and protein deacetylase inhibitor, to examine its efficacy and tolerability in patients with relapsed/refractory indolent lymphoma. Patients and Methods In this open label phase II study (NCT00253630), patients with relapsed/refractory follicular lymphoma (FL), marginal zone lymphoma (MZL), or mantle cell lymphoma (MCL), with ≤ 4 prior therapies were eligible. Oral vorinostat was administered at a dose of 200 mg twice daily on days 1 through 14 of a 21-day cycle until progression or unacceptable toxicity. The primary end point was objective response rate (ORR), with secondary end points of progression-free survival (PFS), time to progression, duration of response, safety, and tolerability. Results All 35 eligible patients were evaluable for response. The median number of vorinostat cycles received was nine. ORR was 29% (five complete responses [CR] and five partial responses [PR]). For 17 patients with FL, ORR was 47% (four CR, four PR). There were two of nine responders with MZL (one CR, one PR), and no formal responders among the nine patients with MCL, although one patient maintained stable disease for 26 months. Median PFS was 15.6 months for patients with FL, 5.9 months for MCL, and 18.8 months for MZL. The drug was well-tolerated over long periods of treatment, with the most common grade 3 adverse events being thrombocytopenia, anemia, leucopenia, and fatigue. Conclusion Oral vorinostat is a promising agent in FL and MZL, with an acceptable safety profile. Further studies in combination with other active agents in this setting are warranted.

Purpose The prognosis for women with recurrent and metastatic endometrial cancer is poor, and improved therapies are needed. The mammalian target of rapamycin (mTOR) pathway is an important target, and mTOR inhibitors show clinical activity in endometrial cancer. Patients and Methods An open-label, multicenter, randomized, phase II trial of oral ridaforolimus compared with progestin or investigator choice chemotherapy (comparator) was undertaken in women with metastatic or recurrent endometrial cancer who had progressive disease following one or two lines of chemotherapy and no hormonal therapy. The primary end point was progression-free survival (PFS) assessed by independent radiologic review. Results One hundred thirty patients were enrolled (64 received ridaforolimus and 66 received the comparator), and median age was 66 years. Treatment discontinuation as a result of adverse events was 33% with ridaforolimus versus 6% with the comparator, with common (> 10%) grade 3 toxicities being hyperglycemia, anemia, and diarrhea. Thirty-eight percent (ridaforolimus) versus 71% (comparator) of patients discontinued treatment as a result of disease progression. Median PFS at the protocol prespecified interim analysis with 58 PFS events (primary end point) was 3.6 months (95% CI, 2.7 to 7.3 months) for ridaforolimus and 1.9 months (95% CI, 1.9 to 2.3 months) for the comparator (hazard ratio, 0.53; 95% CI, 0.31 to 0.90; P = .008). PFS rate for ridaforolimus versus comparator was 48% versus 18% at 16 weeks and 38% versus 15% at 24 weeks. Objective response rate for ridaforolimus versus comparator was 0% versus 4% (P = .925), and stable disease was achieved in 35% versus 17% of patients (P = .021). Conclusion Oral ridaforolimus shows encouraging activity in advanced endometrial cancer but is associated with significant toxicity. Inhibition of the PI3K/Akt/mTOR pathway may be a viable therapeutic target.

1001 Background: Preclinical data identified a synergistic role for P and hormone blockade in blocking growth of ER+ breast cancer (BC) cell lines. PALOMA-1 was an open-label phase II trial comparing progression-free survival (PFS) in patients (pts) with advanced ER+/HER2– BC treated with P+L or L alone. Median PFS increased with addition of P to L to 20.2 mos (vs 10.2 mos with L alone; HR = 0.488), with an acceptable safety profile, leading to accelerated approval by the US FDA. These results were confirmed in the phase 3 PALOMA-2 trial. At the time of the final PFS analysis, overall survival (OS) data were immature with only 61 events in both arms and a median follow-up of < 30 mos with a trend in favor of P+L vs L (37.5 vs 33.3 mos; HR = 0.813; P= 0.211). Here we present final OS results. Methods: PALOMA-1 was a 2-part study evaluating P+L in ER+/HER2– advanced BC. Part 1 enrolled postmenopausal pts with this subtype using only ER+/HER2– while Part 2 enrolled pts of this subtype additionally screened for CCND1 amplification and/or loss of p16. The primary endpoint was investigator-assessed PFS. Secondary endpoints included objective response rate, OS, safety, and correlative biomarker studies. A total of 165 pts were randomized; 66 in Part 1 and 99 in Part 2. Baseline characteristics were balanced between treatment arms. In both parts, pts were randomized 1:1 to receive P+L or L alone. OS data were collected as well as post-study therapy. Results: As of Dec 2016, there were 116 OS events. Median OS was 37.5 mos (95% CI: 31.4, 47.8) with P+L vs 34.5 mos (95% CI: 27.4, 42.6) for L (HR = 0.897 [95% CI: 0.623, 1.294]; P= 0.281). Median OS was 37.5 vs 33.3 mos (HR = 0.837; P= 0.280) for Part 1 and 35.1 vs 35.7 mos (HR = 0.935; P= 0.388) for Part 2. 78.6% of pts in the P+L arm received post-study systemic therapy vs 86.4% in the L arm. More pts in the L arm received ≥3 lines of therapy (37% vs 18%). Further subgroup analyses and details on post-study therapies will be presented. Conclusions: In PALOMA-1, P+L provided a statistically non-significant trend towards an improvement in OS. Survival data from the phase III, PALOMA-2 study is awaited. Sponsor: Pfizer; Clinical trial information: NCT00721409.

7610 Background: The development of nab-paclitaxel has circumvented many of the infusion difficulties that are associated with standard solvent based paclitaxel (in cremophor). In this open label, phase II trial, patients with advanced (stage IIIB or IV) nonsquamous NSCLC received the combination of nab-paclitaxel, carboplatin and bevacizumab. Methods: 50 patients were enrolled between October 2005 and April 2006. Patients received intravenous (IV) nab-paclitaxel 300 mg/m2, carboplatin IV AUC=6, and bevacizumab 15 mg/kg on day 1 of each 21-day cycle. Responding patients received at least 4 cycles of treatment; however, therapy was discontinued for patients with progression or intolerable toxicity. The primary endpoint was response rate based on RECIST. Results: The median patient age was 67 years; 80% were white and 56% were female. Patients received a median of 4 cycles (range, <1–6). The preliminary efficacy results are PR 30% and SD 48%; no complete responses were noted. Median progression-free survival was 7.1 months (range, <1–10.6); median survival has not yet been reached. Grade 3–4 treatment related toxicities were neutropenia (52%); fatigue (19%); neuropathy (15%); thrombocytopenia (10%) dyspnea (6%), anorexia, constipation, febrile neutropenia, hemoptysis, and nausea and/or vomiting (4% each). 64% of patients are currently alive. 32 patients have come off study, prior to 4 cycles due to disease progression (12%), adverse event (10%), investigator request (8%), sudden death (6%), and withdrawal of consent (2%); 16 patients had normal study completion (completed 4 cycles of therapy). Conclusions: This combination of nab-paclitaxel, carboplatin and bevacizumab was well tolerated, with moderate neutropenia. Adverse events were manageable. The preliminary analysis from this study indicates that this combination has promising activity in first-line patients with non-squamous NSCLC. This research was supported, in part, by a research grant from Abraxis BioScience, Inc., Santa Monica, CA. No significant financial relationships to disclose.

6022 Background: Dasatinib is a potent inhibitor of src-family kinases, ephA2, PDGFR, Abl, and c-kit. A single-center, open-label, phase II trial was conducted to evaluate the safety, tolerability, pharmacokinetics (PK), and efficacy of dasatinib in recurrent or metastatic HNSCC. Methods: Pts with measurable disease by RECIST, who received 0 or 1 prior regimen for recurrent or metastatic HNSCC with an ECOG performance status 0–1 and tumor tissue appropriate for IHC and FISH were eligible. Dasatinib 100 mg bid was given for 28-day cycles. Primary endpoints were 12-wk progression-free survival (PFS) and objective response rate (ORR). Pts who took at least 1 dose of dasatinib and who died or left study before 12 wks were counted as progressive disease (PD). A 2 stage design, closure after accrual of 15 pts was required if PFS was 45% or less and ORR was 0. Otherwise, planned accrual was 35. Response was assessed at 4 and 12 wks. PK was studied in pts receiving dasatinib per PEG. Biomarkers relevant to Src pathway were planned in tissue and blood. Results: Fifteen pts were accrued. To date, 13 pts are evaluable for response, and 15 pts for toxicity. No grade 3/4 hematologic toxicities were noted. Grade 2–4 nonhematologic toxicities(n): pleural effusion(2), nausea/vomiting(2), dehydration(1), diarrhea(1), dyspnea(1). Toxicity led to hospitalization of 4 pts and drug discontinuation in 5 pts. ORR was 0. One pt was stable at 12 wks (PFS: 7.6%). This pt stopped drug at 15 wks due to toxicity, but also had PD. One pt died on study and cause was deemed unlikely related. Conclusions: Dosed at 100mg bid, dasatinib led to a characteristic toxicity profile in this pt population. Rates of hospitalization and discontinuation for toxicity were fairly high. Final efficacy parameters are pending evaluation of 2 pts. Evaluation of PK and tissue/blood biomarkers is ongoing. No significant financial relationships to disclose.

5036 Background: ABT-869 is a novel, orally active and potent inhibitor of all VEGF and PDGF receptor tyrosine kinases. Results from a phase I study suggested antitumor activity in advanced solid tumors including RCC. The recommended dose for phase II investigation was 0.25 mg/kg (maximum 25 mg) daily. Methods: We conducted an open-label, multicenter phase II trial of oral ABT-869 in advanced RCC. Eligibility criteria included progressive disease (PD) within 100 days of enrollment after at least 2 cycles of sunitinib, prior nephrectomy, and adequate organ function. The primary endpoint was objective response rate (ORR) per RECIST by central imaging. Secondary endpoints were best response, time to progression (TTP), progression free survival (PFS), and overall survival (OS). Safety was assessed by NCI-CTCAE, v3.0. Results: 53 patients (pts, median age, 61 y [range, 40–80]; clear-cell histology [41 pts]; median number of prior therapies, 2 [range, 1–4]) were enrolled from 8/07 to 10/08. All pts were previously treated with sunitinib, and additional prior treatments included cytokine (19%), sorafenib (15%), temsirolimus (4%), and bevacizumab (4%). Preliminary efficacy data are shown in the Table below. Median TTP was 4.9 mos [95% CI: 3.5–6.8] per central imaging. Median OS is not estimable. The most common adverse events (AEs) were diarrhea (78%), fatigue (67%), hypertension (53%), nausea (51%) and vomiting (39%). AEs ≥ grade 3 included hypertension (24%), fatigue (18%), diarrhea (14%) and hand-foot syndrome (14%). 39 pts required dose reductions. Of the 20 pts who have discontinued therapy at the time of this analysis, 16 were due to PD, 3 due to AEs (1 hemoptysis, 1 fatigue, 1 fatigue/hypertension) and 1 withdrew consent. The remaining 33 pts continue protocol treatment, and updated results will be presented. Conclusions: ABT-869 has activity in RCC after sunitinib failure. The dose will be optimized for future studies. [Table: see text] [Table: see text]

485 Background: Vascular endothelial growth factor receptor inhibitors, including axitinib (AG-013736), may be useful in treating patients with mCRC. The goals of this study were to estimate the objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and safety in patients with mCRC treated with mFOLFOX-6 combined with axitinib or bevacizumab or both. Methods: Patients with mCRC untreated with any systemic chemotherapy >12 months prior to enrollment, ECOG PS 0/1, adequate organ function, and controlled hypertension were eligible for this randomized, open-label, phase II study. Patients receiving prior treatment with antiangiogenic agents or those who were pregnant were ineligible. All patients received standard mFOLFOX-6 treatment and were randomized to receive either axitinib 5 mg (Arm A), or bevacizumab 5 mg/kg (Arm B), or axitinib 5 mg + bevacizumab 2 mg/kg (Arm C). Axitinib was administered orally twice daily. Efficacy was determined by RECIST criteria. Results: A total of 42, 43, and 41 patients were enrolled in Arms A, B, and C, respectively. The ORR was 29%, 49%, and 39% for Arms A, B, and C, respectively. Median PFS was 315 days, 350 days, and 377 days, with 1-year survival of 72%, 79%, and 80% for Arms A, B, and C, respectively. Discontinuations due to adverse events (AEs) were more common in Arm A (36%), than in Arms B (19%) or C (32%). More patients withdrew from Arm A (18%) than from Arms B (5%) or C 12%). The rates of grade 3 AEs were similar across arms, except for hypertension and fatigue which were more common in Arms A (15% and 12%) and C (21% and 29%) compared with Arm B (2% and 12%). Serious AEs were reported by 41%, 40%, and 56% of patients in Arms A, B, and C, respectively; the most common were gastrointestinal disorders (21%, 16%, 15%, respectively). Conclusions: In combination with mFOLFOX-6 chemotherapy, treatment with axitinib resulted in a lower ORR but comparable survival to bevacizumab and this did not appear to improve significantly in the presence of both agents. This result may have been affected by the higher numbers of discontinuations and withdrawals in Arm A compared with the other 2 arms. [Table: see text]
