2506 Background: Alrizomadlin (APG-115) restores TP53 function, activating p53-mediated apoptosis in tumor cells with wild-type TP53 and/or MDM2 amplification. Alrizomadlin also functions as a host immunomodulator and hence may restore antitumor activity in pts with cancers failing PD-1/PD-L1 blockade. Methods: This US multicenter trial assessed alrizomadlin combined with pembrolizumab in pts with unresectable/metastatic melanoma or advanced solid tumors that had failed I-O drugs; or pts with malignant peripheral nerve sheath tumor (MPNST), liposarcoma, or ATM mutant solid tumors that had failed any standard therapy. Eligible pts had ECOG performance status of 0-2 and no CNS metastases. The phase II study cohorts included pts with melanoma, NSCLC, solid tumor with ATM mutation, well-differentiated/dedifferentiated liposarcoma, urothelial carcinoma, and MPNST. Alrizomadlin was administered orally at 150 mg once every other day for 2 consecutive weeks with 1 week off and pembrolizumab at 200 mg via IV infusion for 30 minutes on Day 1 of a 21-day cycle. Results: As of December 25, 2020, 84 pts had been treated in 6 cohorts: melanoma (n = 26), NSCLC (n = 23), ATM mutation (n = 9), liposarcoma (n = 14), urothelial (n = 9), and MPNST (n = 3). In the PD-1/PD-L1 inhibitor-failed melanoma cohort, there was 1 confirmed partial response (PR) out of 5 pts with uveal melanoma, 2 PR (1 confirmed and 1 unconfirmed) of 5 pts with mucosal melanoma, and 1 confirmed PR of 11 pts with cutaneous melanoma. ORR in the melanoma cohort was 17.4% (4/23 evaluable pts), and the disease control rate was 60.9% (14/23). In the MPNST cohort, 1 of 3 pts had an unconfirmed ongoing PR. In I-O drug-failed NSCLC (n = 14 evaluable) and urothelial (n = 5 evaluable) cohorts, each reported 1 confirmed PR. Common treatment (alrizomadlin or pembrolizumab)-related adverse events (TRAEs) (≥ 10%) were nausea (63.1%), thrombocytopenia (36.9%), vomiting (33.3%), fatigue (31.0%), decreased appetite (27.4%), diarrhea (21.4%), neutropenia (15.4%), and anemia (11.9%). Grade ≥ 3 TRAEs (≥ 5%) included thrombocytopenia (20.2%), neutropenia (14.2%), and anemia (8.3%). Eleven pts discontinued treatment due to AEs: 5 were treatment related, including 2 grade 4 thrombocytopenia, and 1 each of grade 2 vomiting, grade 2 fatigue, and grade 2 posterior reversible encephalopathy syndrome (PRES). Three treatment-related SAEs were PRES, pyrexia, and asthenia. Conclusions: Alrizomadlin combined with pembrolizumab is well tolerated and may restore antitumor effects in pts with cancer resistant to or intolerant of I-O drugs, as suggested by preliminary antitumor activities in multiple tumor types.

4098 Background: Lenalidomide inhibits fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF) and multiple tumor growth pathways. There is no standard of care for patients who progress after sorafenib. Therefore, we performed a phase II study to determine the activity of lenalidomide in second-line HCC therapy. Methods: Patients with advanced HCC who progressed on or were intolerant to sorafenib were eligible. Prior chemoembolization, RFA, or surgery were allowed. Eligibility criteria also included bilirubin <4 mg/dL, AST and ALT <5 times upper limit of normal, ECOG performance status 0-2, platelet count >60,000/mm3, absolute neutrophil count >1000/mm3, and creatinine <2mg/dL. Patients were treated with lenalidomide 25mg orally days 1-21 of a 28 day cycle until disease progression or unacceptable toxicities. The planned original sample size was 25 patients but when early activity was demonstrated the study was expanded to 40 patients. Results: The study has completed accrual of 40 patients. The median age was 60.5 years (17-88 years). Nineteen patients were Child-Pugh A, 16 patients were B, and 5 patients were C. Twenty four patients had extrahepatic disease. Preliminary data is available on the first 37 patients. One patient had grade 4 neutropenia. Grade 3 toxicities included ANC (n=2), fatigue (n=4), rash (n=2), arthritis (n=1), diarrhea (n=1), dehydration (n=2). One patient developed variceal bleeding which precipitated encephalopathy and death. Of the 32 patients with elevated baseline AFP, nine (28%) had a >50% reduction including one patient with a reduction in AFP from 56,900ng/ml to 5 ng/ml. Six of the first 37 patients (16%) had a radiographic partial response. Two patients achieved a complete response and have not progressed at 36 and 32 months. Conclusions: Lenalidomide can be administered to patients with advanced HCC and significant hepatic dysfunction. Promising, and in a small percentage of patients, dramatic and durable activity has been demonstrated. Investigations are underway to explore the mechanism of action of lenalidomide in HCC.

15573 Background: Ispinesib is a novel kinesin spindle protein inhibitor that has significant antitumor activity in multiple tumor models and has demonstrated preliminary clinical activity in early phase I and II trials. A phase II study of Ispenisib in patients with metastatic RCC who had received at least one prior therapy was thus conducted. Methods: The primary objective was to assess the RECIST based overall response rate (RR) with optimal Simon two-stage design utilizing 10% and 30% RR as the null and alternative hypotheses, respectively. Eighteen pts were to be accrued during the first stage; if 3 or more responses (PR or CR) were seen, an additional 17 pts would be accrued. Further study would be recommended if 7 or more of the 35 total pts had a response. Secondary objectives included toxicity, time to progression, and overall survival. Pts were treated with 7 mg/m2 over one hour on days 1, 8, and 15 every 28 days with radiologic disease re- evaluation every 8 weeks. Results: 19 pts were accrued in 6 months. Baseline characteristics included clear cell histology in 74%, papillary in 11%, and unclassified in 11%; 1 or =2 prior therapies in 37% and 63%; prior immunotherapy in 53%, and prior sunitinib, sorafenib or bevacizumab in 79%; ECOG performance status 0 in 58% and 1 in 42%. 4 patients are too early for radiologic assessment. None of the 15 patients evaluable responded to treatment (95% CI: 0 - 21.8%). Seven patients (47%) experienced stable disease after 8 weeks. One patient experienced grade 3 neutropenia. No other grade 3 or 4 toxicities were attributable to drug. Grade 1 and 2 toxicities included: fatigue (28%), anemia (28%), leukopenia (33%), elevated alkaline phosphatase (18%), anorexia (11%), hyponatremia (11%), dyspnea (11%), headache (11%), and hypoalbuminemia (11%). Conclusions: Treatment with weekly Ispenesib in metastatic RCC is well tolerated but does not lead to objective responses. Under the hypothesis that Ispenesib is a cytotoxic rather than cytostatic agent, further evaluation in patients with metastatic RCC at this dose and schedule is not indicated.

Consolidation Phase

5549 Background: With the improvement seen with CCRT in the management of locoregionally advanced HNSCC, distant failures have become a more relevant problem in terms of survival. As a consequence, more effective strategies including consolidation chemotherapy are warranted. The primary objective of this pilot phase II study was to assess the feasibility and efficacy of docetaxel and cisplatin consolidation following primary CCRT for HNSCC. Methods: Thirty-three patients with previously untreated, stage III/IV HNSCC participated in this study. CCRT consisted of cisplatin 100 mg/m2 on day 1, 22 and 43. Concurrent radiotherapy (70 Gy) to the primary tumor and neck was performed over a period of 7 weeks. After completion of CCRT, patients with no evidence of disease progression received an additional 4 cycles of consolidation chemotherapy with docetaxel 75 mg/m2 and cisplatin 75 mg/m2 every 3 weeks. To minimize the expected accrual into unacceptable treatment, either in terms of clinical response or toxicity, a total of 35 patients would be required in a two-stage design. Results: Baseline characteristics were: male (22), median age (60 years), ECOG performance status 0/1 (15/18), stage III/IV (10/23). Of these, 27 (81%) patients completed CCRT. After CCRT, 3 complete and 19 partial responses were recorded, giving an overall response rate of 67% (95% CI, 51–83%). Of the 19 patients who went to consolidation phase, only 4 (21%) completed all 4 cycles of docetaxel and cisplatin. Failure to consolidation chemotherapy was attributed to the following causes: toxicity (11 including 3 treatment-related deaths), disease progression (4). During consolidation chemotherapy, 13 patients (68%) had grade 3/4 neutropenia and febrile neutropenia occurred in 6 (32%). With consolidation chemotherapy, one patient with initial stable disease achieved a partial response. Median survival in all patients was 11.0 months, and 8.3 months for those treated with consolidation chemotherapy. Conclusions: The poor compliance and the high incidence of severe toxicities, including 3 treatment-related deaths, prompted no further evaluation of this consolidation chemotherapy following CCRT. No significant financial relationships to disclose.

18011 Background: Recurrent SCLC has a poor prognosis and is devoid of treatment options that improve overall survival. Irinotecan and paclitaxel are both active agents against SCLC, and have synergistic preclinical interactions. We conducted a phase II study to evaluate the efficacy and safety of the combination of irinotecan and paclitaxel for patients with recurrent SCLC. Methods: Patients with SCLC who relapsed following one prior chemotherapy regimen were eligible. Other pertinent inclusion criteria were: ECOG performance status 0–2, adequate bone marrow, hepatic and renal function and willingness to provide informed consent. Patients with untreated brain metastasis were excluded. Paclitaxel (75 mg/m2) and irinotecan (50 mg/m2) were administered on days 1 & 8 of every 3-week cycle. Treatment was continued until progression up to a maximum of 6 cycles or unacceptable toxicity. The primary endpoint was response rate. Toxicity was graded by CTC version 2.0. The simon two-stage design was utilized and the estimated sample size was 55 patients (stage I - 23 patients; stage 2 - 32 patients). The study has a 90% power to detect a response rate of 30%, with an alpha error rate of 10%. Results: 55 patients have been enrolled and complete data are available for 32 patients at the time of this report. Patient baseline characteristics are: male 53%, PS 0–44%; PS 1–47% and PS 2–6%. The median age is 61 years. Fifteen patients received ≥ 4 cycles. Salient grades 3–5 toxicities seen: neutropenia (13%), fatigue (13%); diarrhea (3%), hypersensitivity (3%) and hyponatremia (3%).The objective response rate is 37% (95% CI 19%-55%) with 9 PRs and 1 CR. Additional 8 patients (24%) had stable disease. The median survival is 19.6 weeks (95% CI 15.1–29.4) and the 1-year survival rate is 15%. Conclusions: The combination of irinotecan and paclitaxel is well tolerated and has promising anti-cancer activity in recurrent SCLC. Updated data on all 55 patients will be available at the time of the presentation. No significant financial relationships to disclose.

e15612 Background: A phase I study showed the feasibility of the triplet combination (OPF) with XRT in ES and GE cancer (Maurel et al, IJRBOP, 2005). We conducted a phase II study to evaluate the efficacy of the regimen. Methods: Enrolled pts had resectable, high-risk (HR) based on endoscopic ultrasonography (EUS) (uT3, uN1 or uT4 if deemed resectable) ES, GE and G cancer. The primary objective was to determine the pathologic complete response (pCR). If 2 or more pCR were reported in the first 18 pts treated, enrollment continues with 23 additional pts. Eligibility criteria: squamous cell or adenocarcinoma of the ES, GE or G cancer and ECOG Performance status (PS) 0–1. Staging was done with EUS and computed spiral tomography. Laparoscopic staging was mandatory for pts with ES, GE and G adenocarcinoma. Pts received 2 cycles of O 85 mg/m2, P 55 mg/m2, F (3 g/m2 in 96h CI) q4w, with concomitant 45 Gy XRT in 25 fractions; surgery was planned 5–8 weeks after XRT. All pathological specimens were reviewed by a unique pathologist and regression analysis was recorded using Cologne (C) and M.D.Anderson (MDA) classification for ES and European Journal of Surgical Oncology (EJSO) for GE and G. Results: Between 5/04 to 12/07, 41 pts were enrolled in 5 Spanish Institutions. Median age 62 yrs (39–75 yrs); Male/female 83%/17%; PS 0/1 27%/73%; ES/GE/G 39%/32%/29%; EUS stageT3N0 (20%), T2–3N1 (65%) and T4 (10%). G3/4 adverse events included asthenia (27%), infection (7%), diarrhea (7%) and stomatitis (5%). There were 2 toxic deaths. Of the 31 pts who underwent surgery, there were R0=94%/R1=3%/R2= 3%. 7/41 pts (17%) achieved pCR. Using C and MDA classification, 9/14 (61%) and 12/14 (85%) ES achieved grade IV/III and P0/P1 regression, respectively. With EJSO classification 3/17 (18%) GE and G tumors achieved pCR. Median time to progression or death (PFS) was 16.2 (CI:12.2-NR) months (mo). Median overall survival (OS) was 28.9 mo. (CI: 22.5-NR). Conclusions: Although in the whole group pCR, PFS and OS does not appear superior to results achieved in other trials with preoperative P/F/XRT in HR pts, the OPF regimen seems specially active in ES cancer.

e19062 Background: Combination chemotherapy with carboplatin-docetaxel has been shown to be effective and safe for patients with locally advanced or metastasized NSCLC. The monoclonal anti-EGRF antibody cetuximab has the potential to improve response rates and survival without a substantial increase in toxicity when given in combination with chemotherapy. Methods: Open, non-controlled phase II study with a planned sample size of 70 pts. Pts with locally advanced or metastasized NSCLC, ECOG performance status ≤ 2 and no prior systemic chemotherapy were treated with carboplatin AUC5 (d 1) q4w for 4–6 cycles and docetaxel 35 mg/m2 (d1, 8, 15) q4w; cetuximab 400 / 250 mg/m2 (d 1) q1w until progression or intolerable toxicity (12 month max.). The primary endpoint was response rate defined as complete or partial remission according to RECIST. Secondary endpoints were toxicity, 1 year survival, median and progression free survival. Results: Subject of the interims analysis were 27 pts (25 stage IV, 2 stage IIIb). ECOG 0/1/2 was 33.3%/59.3%/3.7% (1 no data). 63% had prior surgery, 93% prior radiotherapy and all had adjuvant or inductive chemotherapy. Pts received a mean of 3 ± 1.4 cycles docetaxel-carboplatin-cetuximab. 49 adverse events were grade 1–2 and 12 grade 3–5. Skin toxicity (49%; 95%CI: 30%-68%; 41% G1/2, 8% G3/4), dyspnoea (35%; 95%CI: 17%-53%) and diarrhoea (23%; 95%CI: 7 %-39%; 19% G1/2, 4% G3) were most frequent. 11 pts (41%) had toxicity leading to dose reduction. 0 pts had complete and 11 pts had partial remission resulting in a response rate of 40.7% (95%CI: 22%-59%) based on intention to treat. 6 pts had stable disease (22.2%; 95%CI: 7%-38%). 5 pts were not evaluable for response. Conclusions: The combination of carboplatin-docetaxel-cetuximab has an overall acceptable tolerability. With a preliminary response rate of 40.7% the benefit risk assessment was found to be favourable and the study was continued. [Table: see text]

8514 Background: Ipilimumab (Ipi) alters the immune system balance by inhibiting the suppression of T-cell function. In two phase III trials, Ipi has shown an overall survival benefit alone and in combination with dacarbazine in previously treated and treatment-naïve patients (pts) with metastatic melanoma (MM), respectively. We performed a single-institution, phase II clinical trial of Ipi plus temozolomide (Tem) in pts with MM. Methods: Pts between the ages of 18 and 75 with previously untreated unresectable stage III or stage IV MM and an ECOG Performance Status of 0 to 1 were enrolled in a phase II trial of Ipi plus Tem. Induction phase consisted of Ipi 10mg/kg intravenous on Day 1 and oral Tem 200 mg/m2 on Days 1 – 4 every 3 weeks for 4 doses. Maintenance consisted of Ipi 10 mg/kg intravenous on Day 1 starting week 12 and repeated every 12 weeks and oral Tem 200 mg/m2 on Days 1 – 5 starting week 12 and repeated every 4 weeks until disease progression or unacceptable toxicity occurred. The primary endpoint was progression-free survival (PFS) rate at 6 months. Responses were evaluated using immune-related response criteria. Results: Sixty-four pts were enrolled and received at least one dose of study drug. All pts were included in the analysis. With a median follow-up of 8.5 months, the PFS rate at 6 months was 43%, exceeding the proposed rate of 30%, and the median PFS was 5.1 months. There were 10 (15.6%) confirmed complete responses and 8 (12.5%) confirmed partial responses. At the time of this analysis, median overall survival has not been reached. Immune-related adverse events (irAEs) were experienced by 88% of pts, most commonly pruritus (88%), rash (83%), diarrhea (56%), transaminitis (45%), and colitis (11%). Grade 3/4 irAEs seen in more than one patient were skin rash (11%), diarrhea (9%), pruritus (6%), and transaminitis (5%). Constipation occurred in 70% of pts and was the most common gastrointestinal (GI) toxicity. There were no GI perforations or deaths on study due to treatment. Conclusions: At a median follow-up of 8.5 months, the best overall response rate in this study is 28%. Ipi at 10 mg/kg in combination with Tem given in an induction followed by maintenance fashion is safe, well-tolerated, and efficacious in MM.

The Impact

TPS3635^ Background: The identification of prognostic and predictive biomarkers could significantly improve the risk-benefit ratio and cost-effectiveness of 1st-line mCRC regimens. This is the first prospective study of tumoral ERCC1 (chemo-resistance marker to platinum compounds) and plasma VEGF-A as potential biomarkers for oxaliplatin- and BV-containing regimens, respectively, in an effort to further define the optimal chemotherapy backbone with biologic therapies, including BV, for mCRC. Methods: In this randomized, open-label, global, phase II study, patients (N=360) with histologically or cytologically confirmed CRC and ≥1 measurable metastatic lesion are stratified at screening by tumoral ERCC1 mRNA expression (high vs low, cutoff of 1.7 [ERCC1/β-actin mRNA]). Eligibility criteria include completion of adjuvant therapy >12 months before screening and an ECOG performance status ≤1. Blood samples are collected to quantify plasma VEGF-A levels. Patients within each ERCC1 stratification group are randomized 1:1 to mFOLFOX6-BV or FOLFIRI-BV administered in 2-week cycles. BV will be given at a dose of 5 mg/kg IV q2w. Patients will remain on study treatment until disease progression (PD) or unacceptable toxicity. If oxaliplatin or irinotecan need to be discontinued, BV and 5-fluorouracil or capecitabine are to be continued until PD. The primary objectives are: 1) to assess ERCC1 and VEGF-A as biomarkers of progression-free survival (PFS) for oxaliplatin- and BV-containing regimens in 1st-line mCRC, and 2) within ERCC1 high patients, to test whether FOLFIRI-BV is associated with a prolonged 1st-line PFS compared to mFOLFOX6-BV. Secondary objectives include assessing the impact of these markers on overall survival, objective response, hepatic metastases resection, and safety. Exploratory endpoints include correlative analyses with additional tumor tissue, blood, and SNP markers. The first patient was enrolled in August 2011. An interim biomarker distribution assessment of the first 100 patients is planned, and the evaluation of the primary endpoints is estimated for early 2015. Clinicaltrials.gov: NCT01374425.

294 Background: Currently, there are no standard treatments for relapsed or refractory urothelial carcinoma (UC). Discouraging results have been observed in trials evaluating established chemotherapeutics as single agents or in combination regimens. Paclitaxel has moderate activity when used alone and in combination in UC. Pazopanib is active in other solid tumors secondary to its potent anti-angiogenic effects. We report the results of a multi-center phase II study evaluating the combination of paclitaxel with pazopanib in refractory UC. Methods: Eligible patients (pts) had histologically confirmed UC, with disease that progressed on upto 2 chemotherapeutic regimens. Pazopanib (800 mg) was administered daily, with weekly paclitaxel (80mg/m2) for 3 weeks in a 28 day cycle. Treatment was continued until disease progression or unacceptable toxicity. The primary endpoint of the study was response-rate (RR) based on RECISTv 1.1 criteria. Secondary endpoints included safety, and progression free-survival (PFS). Results: From April 2010 to September 2014, 32 patients were enrolled. Median age was 67 years (29-89) and median ECOG performance status was 1 (0-2). 17 pts (54%) had UC of the upper urinary tract disease and 15(47%) had primary bladder tumors. All pts had multiple metastatic sites, including 9 (28%) with liver metastases. Median number of prior cytotoxic regimens was 2, and 50% were considered cisplatin responsive. Objective responses were observed in 58% with 3 (12%) complete responses (CR), and 12 pts (46%) with partial responses (PR). Another 9 (35%) acheived stable disease (SD). High grade toxicities included grade 3 hypertension (n=2), grade 3 fatigue (n=4), grade 3 thrombosis (n=2) and grade 4 neutropenia (n=2). Nearly half of the patients( n= 14 ) required growth factor support. Conclusions: Our phase II study combining paclitaxel and pazopanib demonstratedsignificant anti-tumor activity in relapsed/refractory UC. This combination is safe, effective and is worthy of evaluation in randomized phase 3 study. Clinical trial information: NCT01108055.
