312 Background: In the RECORD-1 phase III study, the mammalian target of rapamycin (mTOR) inhibitor everolimus (ClinicalTrials.gov: NCT00410124 ) prolonged progression-free survival (PFS) versus placebo (median PFS 4.9 vs 1.9 months) in patients with mRCC whose disease progressed during or within 6 months of VEGFr-TKI (sunitinib and/or sorafenib) therapy. In this retrospective analysis, we evaluated the effect of everolimus on PFS in the subgroup of patients who discontinued prior VEGFr-TKI therapy because of adverse events. Methods: In the randomized, double-blind RECORD-1 trial, patients with mRCC who had prior VEGFr-TKI therapy were randomized (2:1) to receive everolimus 10 mg/day (n = 277) or placebo (n = 139) plus best supportive care. Results: Patients who were intolerant of prior VEGFr-TKI therapy included 50 patients (sunitinib = 26; sorafenib = 24) in the everolimus group and 13 patients (sunitinib = 5; sorafenib = 8) in the placebo group. The median PFS in the sunitinib group was 5.13 mo (95% confidence interval [CI]: 3.71, not available [NA]) in patients receiving everolimus vs 2.81 mo (95% CI: 1.87, 3.71) in those receiving placebo (HR: 0.28; 95% CI: 0.07, 1.18; p = 0.033). In the sorafenib subgroup, median PFS was 5.59 mo (95% CI: 3.78, NA) versus 1.91 mo (95% CI: 1.68, 3.48), respectively (HR: 0.29; 95% CI: 0.09, 0.91; p = 0.012). Conclusions: Everolimus prolonged PFS in a subgroup of patients with mRCC who were intolerant of prior VEGFr-TKI therapy. These results suggest that mTOR inhibition with everolimus was active in patients with mRCC who were intolerant of a previous VEGFr-TKI. [Table: see text]

304 Background: The mammalian target of rapamycin (mTOR) inhibitor everolimus is the only medication to have shown efficacy in a randomized, controlled, phase III clinical trial (RECORD-1) in pts with mRCC after progression on VEGFR-TKIs. Everolimus more than doubled progression-free survival (PFS) vs. placebo (4.9 vs 1.9 months) and reduced the risk of disease progression by 67%. This analysis evaluated the effect of everolimus on survival in pts who had received 1 vs 2 prior VEGFR-TKIs. Methods: Pts with mRCC who progressed on sunitinib (SU) and/or sorafenib (SOR) were randomized (2:1) to receive everolimus 10 mg/day (n = 277) or placebo (n = 139) plus best supportive care in the double- blind, phase III RECORD-1 study (ClinicalTrials.gov: NCT00410124 ). Results: Before enrollment, the majority of pts received only 1 VEGFR- TKI (317 pts, 74%), with 317 pts receiving either SU or SOR (everolimus = 211; placebo = 106) and 99 pts receiving both SU and SOR (everolimus = 66; placebo = 33). Median PFS was 5.42 mo (95% confidence interval [CI]: 4.30, 5.82) in pts receiving everolimus who had received 1 prior VEGFR-TKI and 1.87 mo (95% CI: 1.84, 2.14) in those receiving placebo (hazard ratio [HR]: 0.31; 95% CI: 0.23, 0.42; p < .001). Median PFS was 3.78 mo (95% CI: 3.25, 5.13) for the everolimus group in pts who received 2 prior VEGFR-TKIs, versus 1.87 mo (95% CI: 1.77, 3.06) for the placebo group (HR: 0.37; 95% CI: 0.22, 0.63; p < 0.001). Conclusions: Pts in all stratified subgroups derived significant clinical benefit from everolimus treatment, including pts previously treated with either 1 or 2 VEGFR-TKIs. However, there was a trend toward a longer PFS in pts treated with 1 prior VEGFR-TKI compared with 2 VEGFR-TKIs. [Table: see text]

9 Background: Advanced Oesophago-Gastric Carcinoma (AOGC) has limited options following failure of first or second line chemotherapy (CT). Regorafenib (REG) is an oral multi-kinase inhibitor of kinases involved in angiogenesis, tumor microenvironment, and oncogenesis. This study examined whether REG has sufficient activity and safety for further evaluation. Methods: International (Australia & New Zealand (ANZ), Korea, Canada (NCIC CTG)) randomised phase II trial with 2:1 randomisation and stratification by: (1) Lines of prior CT for advanced disease (1 vs. 2) and (2) Region. Eligible patients received best supportive care plus 160mg REG or matching PBO orally on days 1-21 each 28-day cycle until disease progression or prohibitive adverse events. Primary endpoint was progression free survival (PFS) in the REG arm, assuming median 8 weeks (wks) in PBO arm, aiming for 13.2 wks with REG to be of interest. Results: From Nov 2012 to Feb 2014, 152 patients were enrolled, 147 evaluable [pre-specified primary analysis population]: (REG n=97: PBO n=50); well matched for key baseline prognostic indicators; male:female (118:29); primary location: OG Junction (56), stomach (85); lines of prior therapy: 1 (63), 2 (84); ECOG 0 (62): 1 (85). Time on treatment: Median: 7.9 (REG) v 4 (PBO) wks. In the evaluable population median PFS was 11.1 wks (95% CI: 7.7 - 12.3) (REG) and 3.9 wks (95% CI: 3.7 - 4.0) (PBO), log-rank p <0.0001; HR 0.41 (95% CI: 0.28 to 0.59). PFS results were maintained for secondary analysis including all randomized patients (n = 152). REG was well tolerated, with the spectrum of toxicity in keeping with previous reports. Conclusions: PFS was clearly significantly longer with REG than PBO, though PBO PFS was less than anticipated. The pre-specified exploratory comparisons provide compelling evidence that REG has sufficient activity with acceptable tolerability in refractory AOGC to warrant phase III evaluation. Mature OS results will be presented at the meeting. Clinical trial information: 12612000239864.

Purpose Erlotinib is a potent inhibitor of the epidermal growth factor receptor tyrosine kinase, with single-agent antitumor activity. Preclinically, erlotinib enhanced the cytotoxicity of chemotherapy. This phase III, randomized, double-blind, placebo-controlled, multicenter trial evaluated the efficacy and safety of erlotinib in combination with cisplatin and gemcitabine as first-line treatment for advanced non–small-cell lung cancer (NSCLC). Patients and Methods Patients received erlotinib (150 mg/d) or placebo, combined with up to six 21-day cycles of chemotherapy (gemcitabine 1,250 mg/m2 on days 1 and 8 and cisplatin 80 mg/m2 on day 1). The primary end point was overall survival (OS). Secondary end points included time to disease progression (TTP), response rate (RR), duration of response, and quality of life (QoL). Results A total of 1,172 patients were enrolled. Baseline demographic and disease characteristics were well balanced. There were no differences in OS (hazard ratio, 1.06; median, 43 v 44.1 weeks for erlotinib and placebo groups, respectively), TTP, RR, or QoL between treatment arms. In a small group of patients who had never smoked, OS and progression-free survival were increased in the erlotinib group; no other subgroups were found more likely to benefit. Erlotinib with chemotherapy was generally well tolerated; incidence of adverse events was similar between arms, except for an increase in rash and diarrhea with erlotinib (generally mild). Conclusion Erlotinib with concurrent cisplatin and gemcitabine showed no survival benefit compared with chemotherapy alone in patients with chemotherapy-naïve advanced NSCLC.

Purpose To determine whether addition of the farnesyltransferase inhibitor tipifarnib (Zarnestra, R115777; Johnson and Johnson Pharmaceutical Research and Development, Beerse, Belgium) to standard gemcitabine therapy improves overall survival in advanced pancreatic cancer. Patients and Methods This randomized, double-blind, placebo-controlled study compared gemcitabine + tipifarnib versus gemcitabine + placebo in patients with advanced pancreatic adenocarcinoma previously untreated with systemic therapy. Tipifarnib was given at 200 mg bid orally continuously; gemcitabine was given at 1,000 mg/m2 intravenously weekly × 7 for 8 weeks, then weekly × 3 every 4 weeks. The primary end point was overall survival; secondary end points included 6-month and 1-year survival rates, progression-free survival, response rate, safety, and quality of life. Results Six hundred eighty-eight patients were enrolled. Baseline characteristics were well balanced between the two treatment arms. No statistically significant differences in survival parameters were observed. The median overall survival for the experimental arm was 193 v 182 days for the control arm (P = .75); 6-month and 1-year survival rates were 53% and 27% v 49% and 24% for the control arm, respectively; median progression-free survival was 112 v 109 days for the control arm. Ten drug-related deaths were reported for the experimental arm and seven for the control arm. Neutropenia and thrombocytopenia grade ≥ 3 were observed in 40% and 15% in the experimental arm versus 30% and 12% in the control arm. Incidences of nonhematologic adverse events were similar in two groups. Conclusion The combination of gemcitabine and tipifarnib has an acceptable toxicity profile but does not prolong overall survival in advanced pancreatic cancer compared with single-agent gemcitabine.

501 Background: Reports have demonstrated an inverse relationship between suppression of immune surveillance mechanisms and activation of the vascular endothelial growth factor receptor (VEGFR) pathway suggesting that T cell repertoires may impact response to VEGFR blockade. We evaluated the association between clinical outcomes and T cell repertoire in metastatic RCC patients receiving a front-line anti-VEGFR, pazopanib. Methods: Pre-treatment RCC tumors were analyzed from VEG105192, a phase III study of mRCC patients randomized (2:1) to pazopanib (paz) 800 mg daily vs placebo (pbo) for TCR gamma (TCRG) and TCR beta (TCRB) CDR3 regions. Using the Adaptive Biotechnologies immunoSEQ Assay, we assessed TCR clonality, a measure of total repertoire represented by expanded clones, and entropy, a measure of evenness and diversity. PD-L1 was evaluated by immunohistochemistry (IHC) H-Scores. The goal of the study was to determine if the repertoire of T cell clones was associated with progression-free survival as a clinical endpoint. Results: In the cohort with available tissue, the median PFS was 10.8 and 5.5 months (mos) for paz and pbo, respectively. TCRB (n = 114) and TCRG (n = 43 pbo, 109 paz) clonality ranged from 0-0.31 and 0-0.98, and entropy from 1-12.1 and 0-10.37, respectively. TCRB and TCRG entropy were highly correlated (Spearman’s R = 0.92, n = 114). Samples from the pbo-treated group with higher TCRG entropy, defined as the top 25th percentile, were associated with an improved median PFS (12.8 months) when compared to the lower 75th percentile (3.1 months, P = 0.023); similar trends were seen for TCRB entropy. Neither entropy nor clonality was associated with maximal reduction in tumor volume in the paz-treated group. PD-L1 H-scores were not associated with entropy or clonality (P > 0.05). Conclusions: Our data suggests that RCC samples with higher entropy are associated with a favorable prognosis. Identification of tumors with restricted TCRB/G chain usage and less diverse repertoire, as represented by lower entropy and higher clonality, may impact responses to VEGFR blockade and requires further study. Clinical trial information: NCT00334282.

TPS6107 Background: Carboplatin-paclitaxel is considered standard systemic anticancer therapy for recurrent or advanced EC for which surgery and/or radiation are not curative. Dostarlimab (TSR-042) is an anti-programmed cell death (PD)-1 humanized monoclonal antibody that has demonstrated antitumor activity and an acceptable safety profile in patients (pts) with recurrent or advanced EC in the GARNET trial. The RUBY trial was designed to evaluate the efficacy and safety of dostarlimab in combination with carboplatin-paclitaxel in recurrent or primary advanced EC compared with carboplatin-paclitaxel alone. Methods: This is a global, randomized, double-blind, multicenter, placebo-controlled study. Eligible pts must have first recurrent or primary stage III or stage IV EC with a low potential for cure by radiation therapy or surgery alone or in combination. Pts with carcinosarcoma are eligible for enrollment. 470 pts will be enrolled from approximately 160 sites in the ENGOT countries, United States, and Canada. Stratification factors are microsatellite instability (MSI) status (MSI-high [MSI-H] or microsatellite stable [MSS]), prior external pelvic radiotherapy (yes or no), and disease status (recurrent, primary stage III, or primary stage IV). Pts will be randomized 1:1 to receive combination dostarlimab 500 mg or placebo + carboplatin AUC 5 + paclitaxel 175 mg/m2 every 3 weeks for 6 cycles followed by dostarlimab 1000 mg or placebo monotherapy every 6 weeks for up to 3 years in the absence of progressive disease, death, unacceptable toxicity, or patient/physician decision to withdraw from the study. The primary endpoint is progression-free survival (PFS) as assessed by the investigator in the all-comers population and the MSI-H population per RECIST version 1.1. Secondary efficacy endpoints are PFS assessed by blinded independent central review per RECIST version 1.1, overall survival, objective response rate, duration of response, disease control rate, safety and tolerability, and patient-reported outcomes. Clinical trial information: NCT03981796.

Purpose Aberrant mammalian target of rapamycin (mTOR) signaling is common in sarcomas and other malignancies. Drug resistance and toxicities often limit benefits of systemic chemotherapy used to treat metastatic sarcomas. This large randomized placebo-controlled phase III trial evaluated the mTOR inhibitor ridaforolimus to assess maintenance of disease control in advanced sarcomas. Patients and Methods Patients with metastatic soft tissue or bone sarcomas who achieved objective response or stable disease with prior chemotherapy were randomly assigned to receive ridaforolimus 40 mg or placebo once per day for 5 days every week. Primary end point was progression-free survival (PFS); secondary end points included overall survival (OS), best target lesion response, safety, and tolerability. Results A total of 711 patients were enrolled, and 702 received blinded study drug. Ridaforolimus treatment led to a modest, although significant, improvement in PFS per independent review compared with placebo (hazard ratio [HR], 0.72; 95% CI, 0.61 to 0.85; P = .001; median PFS, 17.7 v 14.6 weeks). Ridaforolimus induced a mean 1.3% decrease in target lesion size versus a 10.3% increase with placebo (P < .001). Median OS with ridaforolimus was 90.6 weeks versus 85.3 weeks with placebo (HR, 0.93; 95% CI, 0.78 to 1.12; P = .46). Adverse events (AEs) more common with ridaforolimus included stomatitis, infections, fatigue, thrombocytopenia, noninfectious pneumonitis, hyperglycemia, and rash. Grade ≥ 3 AEs were more common with ridaforolimus than placebo (64.1% v 25.6%). Conclusion Ridaforolimus delayed tumor progression to a small statistically significant degree in patients with metastatic sarcoma who experienced benefit with prior chemotherapy. Toxicities were observed with ridaforolimus, as expected with mTOR inhibition. These data provide a foundation on which to further improve control of sarcomas.
