e14531 Background: This is an open label, non-randomized, multicenter phase I-II study with Docetaxel (Doc) given in combination with capecitabine (Cap) in patients (pts) with metastatic oesophageal cancer (mEC) or cancer in the cardia region (mCCR). Methods: In phase I, pts were treated with Cap day 1-14, 22-36 and Doc day 1, 8, 15, 22, 29. Cap was dose escalated from 1300 mg up to 1650mg/m2 per day according to modified Fibonacci design. The dose of Doc was fixed to 30mg/m2 in both Phase I-II. In Phase II 1650mg/m2 Cap was given. The primary objective in phase I was to define a dose of Cap recommended for the Phase II and to determine the feasibility and safety of this treatment. The primary objective in the phase II was to determine the response rate (RR), safety profile, quality of life and survival.The median age was 64.8 years, PS was 0 in 23 pts, I in 57 and II in 13 pts. The histology was as follows: 58 adenoca, 33 squamous cell ca and 2 poorly diff ca. Forty-three pts had previously been treated with chemotherapy, 41 with radiotherapy, 50 were chemotherapy-naive and 31 had underwent surgery. Results: From March 2006 to Oct 2010, 93 eligible pts with measurable disease were enrolled in the study. Fourteen were treated in phase I and 79 in phase II. Four pts (1 in ph I and 3 in ph II) did not receive any study treatment. Twenty-seven pts of 93 (29%) were not evaluable according to study protocol which included CT after 6 w of treatment due to rapid tumour progression and deterioration of general condition. RR was 29%, 2 CR and 25 PR, 15 pts (16%) had SD and 24 pts (26%) had PD. Median OS was 7.3 months (5.76-8.9) and median PFS was 4.2 months (2.3-4.7 months).Treatment related grad 3 or 4 toxicity was as follows: 60% of pts experienced any grade 3 or 4 toxicity, 30% related to infections, 24% had nausea, diarrhea, vomiting, mucositis, <10% had cardiac related symptoms, <1% had an allergic reaction to Doc. Conclusions: Cap together with Doc appears tolerable and has a RR of 29% in selected group of patients with mET and mCCR. Majority of treatment courses were given on out-patient bases. However, there is un urgent need to define an optimal therapy regime and further studies are warranted.

BackgroundAngiosarcoma is a rare cancer of endothelial cells that can be aggressive and carries a high mortality. A subset of angiosarcomas are characterized by high tumor mutational burden (TMB) and UV light exposure DNA mutational signature. Isolated case reports have suggested clinical efficacy of immune checkpoint blockade in angiosarcoma; no prospective studies of immune checkpoint inhibition in angiosarcoma have been reported. We report efficacy analysis results for patients with advanced or unresectable angiosarcoma treated with ipilimumab and nivolumab as a cohort of an ongoing phase II study for rare cancers (NCT02834013).MethodsThis is a prospective, open-label, multicenter phase II clinical trial of ipilimumab (1mg/kg IV q6weeks) plus nivolumab (240mg IV q2weeks) for patients with metastatic or unresectable angiosarcoma. Primary endpoint is objective response rate as assessed by RECIST v1.1, including measurable cutaneous disease that can be followed by photography. Secondary endpoints include PFS, OS, stable disease at six months, and toxicity. A two-stage design is used with six patients in the first stage and an additional ten patients in the second stage.ResultsAt data cutoff, 16 patients with angiosarcoma were enrolled. Median age was 68 years (25-81 years). Median number of prior lines of therapy was 2 (0-5). 9 patients had cutaneous primary tumors of any cutaneous site, 7 had non-cutaneous primary tumors. ORR for all patients was 25% (4/16, table 1, figure 1). Subgroup analysis revealed that 60% (3/5) of patients with primary cutaneous tumors of the scalp or face had a confirmed objective response. 6-month PFS was 38%. 75% of patients experienced an adverse event (AE), and 25% experienced a grade 3-4 AE. 68.8% experienced an immune related AE (irAE), and 2 (12.5%) developed grade 3 or 4 irAEs. Grade 3-4 irAEs were ALT and AST increase and diarrhea. There were no grade 5 toxicities.ConclusionsThe combination of ipilimumab and nivolumab was well tolerated and had an ORR of 25% in angiosarcoma regardless of primary site, with 3 of 5 patients with cutaneous tumors of the scalp or face responding. Ipilimumab and nivolumab warrant further investigation in angiosarcoma.AcknowledgementsFunding: National Institutes of Health/National Cancer Institute grant awards CA180888, CA180819, CA180868; and in part by Bristol-Myers Squibb CompanyTrial RegistrationNCT02834013Ethics ApprovalThis study was approved by the NCI CIRB.

PURPOSE Targeted therapies against non–small-cell lung cancer (NSCLC) harboring HER2 mutations remain an unmet need. In this study, we assessed the efficacy and safety of pyrotinib in patients with HER2-mutant advanced NSCLC in a prospective, multicenter, open-label, single-arm, phase II study. PATIENTS AND METHODS Patients with stage IIIB or IV HER2-mutant lung adenocarcinoma who were previously treated with platinum-based chemotherapy were enrolled to receive pyrotinib at a dose of 400 mg/d for 21-day cycles. The primary end point was objective response rate per independent review committee (IRC). RESULTS Between October 20, 2016, and December 10, 2018, 60 patients received pyrotinib monotherapy. At baseline, 58 (96.7%) were stage IV, and 25 (41.7%) received at least 2 lines of prior chemotherapy. As of data cutoff on June 20, 2019, IRC-assessed objective response rate was 30.0% (95% CI, 18.8% to 43.2%). All subgroups of patients with different HER2 mutation types showed a favorable objective response rate. The objective response rates were similar between patients with and without brain metastases (25.0% v 31.3%). The median duration of response was 6.9 months (95% CI, 4.9 to 11.1 months). The median progression-free survival was 6.9 months (95% CI, 5.5 to 8.3 months) per IRC. The median overall survival was 14.4 months (95% CI, 12.3 to 21.3 months). Treatment-related adverse events of grade 3 or 4 occurred in 28.3% of patients, with the most common being diarrhea (20.0%; all grade 3). No treatment-related deaths were reported. CONCLUSION Pyrotinib showed promising antitumor activity and an acceptable safety profile in chemotherapy-treated patients with HER2-mutant NSCLC.

Abstract Background: FMS-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) mutation in acute myeloid leukemia (AML) is associated with early relapse and poor survival. Quizartinib potently and selectively inhibits FLT3 kinase activity. In a phase I and II studies the composite response rate (CRR) was approximately 50% among patients with FLT3-ITD. There is in-vitro synergy between quizartinib and 5-AZA or LDAC. We hypothesize that adding quizartinib to a hypomethylating agent such as 5-azacitidine (AZA) or cytarabine may improve the response rate expected from the use of either agent alone. Objectives: The primary objective of phase I part is to determine the dose limiting toxicity (DLT) and maximally tolerated dose (MTD) of the combination of quizartinib (AC220) with either AZA or low-dose cytarabine (LDAC); for phase II is to determine the clinical activity of both combinations. This planned interim analysis reports on the recommended phase II dose (RP2D) and first futility analysis. Methods: For phase I, patients with relapsed/refractory high-risk myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia (CMML) or AML were eligible irrespective of FLT3 mutation and salvage status. For phase II, presence of FLT3-ITD is a requisite. Phase II enrollment is limited to patients >60 years with untreated MDS/CMML/AML, or any age receiving first salvage treatment. Additional eligibilities include performance status ECOG ≤2, adequate organ function, normal electrolytes (potassium, calcium and magnesium). Important exclusions include QTcF> 450 mSec, concomitant drugs that prolong QT/QTc interval or strong CYP3A4 inhibitors or inducers with the exception of antibiotics, antifungals, and antivirals that are used as standard of care. Treatment cycle is defined as 28 days. Treatment comprises of AZA 75 mg/m2 subcutaneously (SQ) or intravenously (IV) for 7 days of every cycle (Days 1-7), or cytarabine 20 mg SQ twice daily for 10 days of every cycle (Days 1-10) along with quizartinib at two planned dose levels: 60 mg (dose level 1) or 90 mg orally daily (dose level 2) uninterrupted. Patients are assigned to AZA or LDAC arm by physician choice or slot availability. Planned accrual for each arm in phase 2 is 26 pts each and an ORR of ≥50% will be considered favorable. Accrual of 26 pts will give a 95% credible interval for overall response rate of (0.32, 0.68). The study will be stopped for toxicity (>30%) and/or futility (ORR <50%) at interim analysis for each arm. Results: Twenty-six (Phase I=12, phase II=14) pts have been enrolled: 18 to AZA arm and 8 to LDAC arm. Median age is 62 years (range, 25-79 years), 7 (27%) are female. Cytogenetics are diploid=14, +8=2, -7=2, miscellaneous=6, 11q and t(8;21)= 1 each. Median number of prior therapies is 2 (range, 0-7), 7 patients received prior FLT3 inhibitor. For both schedules quizartinib 60 mg daily was identified as the recommended phase II dose (RP2D) based on emerging results from separate dose-finding study. Eighteen [5 in LDAC arm (63%) and 13 (72%) in AZA arm; all with FLT3-ITD mutation without D835 mutation] of 26 total pts (69%) have responded (CR=1/ CRp=3/ CRi=2/ MLFS=10/PR=1/HI=1). Among patients with FLT3-ITD (N=22), ORR is 82%. Four of 7 (57%) patients with prior FLT3 inhibitor exposure responded. Median number of days to respond is 57 days (range, 25-102 days). Among responders two patients died (MLFS=1, PR=1): one with gastro-intestinal bleeding and other with progressive pneumonia. Three additional responders have discontinued therapy for stem cell transplant (1), withdrawal of consent (1), and loss of response with emergence of D835 mutation (1). Nine responders (CR=1, CRi=1, CRp=1, PR=1, MLS=5) had >50% reduction of FLT3-ITD allelic burden and 2 additional pts (CR=1, CRi=1) had no detectable FLT3-ITD at response. Number of pts with treatment emergent grade 3/4 toxicities irrespective of attribution include hypokalemia (15), hypophosphatemia (5), hyponatremia (4), hypocalcemia (4), hyperbilirubinemia (3), increase in ALT (1), hypernatremia (1hyperglycemia (1), hypotension (1), QTcF prolongation (1, grade 3). Conclusion: Combination of quizartinib and AZA or LDAC is highly active among patients with AML/MDS/CMML with FLT3-ITD . Response rates appear higher than expected with either agent alone. Clinically significant QTcF prolongation is infrequent. Accrual to both arms of the current trial continues. Disclosures Cortes: Ambit Biosciences: Research Funding.

Results: Fifty-two (Phase I=12, phase II=40) pts have been enrolled: 38 to AZA arm and 14 to LDAC arm. Median age is 67 years (range, 23-83 years), 24 (46%) are female. Cytogenetics are diploid=24, +8=5, monosomy 7=3, miscellaneous=17, 11q=2 and t(8;21)= 1. Median number of prior therapies is 1 (range, 0-7); 7 patients had received prior FLT3 inhibitor: sorafenib (5), crenolanib (1), quizartinib (1). For both combinations quizartinib 60 mg daily was identified as the recommended phase II dose (RP2D). Thirty-five Pts [8 in LDAC arm (23%) and 27 in AZA arm (77%)] of total 52 have responded with ORR 67 % (CR=8, CRp=7, CRi=18, PR=2); all with FLT3-ITD mutation without D835 mutation. ORR is 73% among pts with FLT3-ITD (N=48). Three of eight pts (38%) with prior FLT3 inhibitor exposure responded. Median time to response is 35 days (range, 14-187days). Among responders, two pts died (in CRi=1, PR=1): one with GI bleed and one with progressive pneumonia. Twelve responders discontinued therapy: 11 to receive a SCT and 1 due to loss of response with emergence of D835 mutation. Fifteen responders (CR=2, CRi=8, CRp=3, PR=2) had >50% reduction of FLT3-ITD allelic burden and eight additional pts (CR=5, CRi=1, CRp=2) had no detectable FLT3-ITD at response. The median survival was: 14.8 mo for the total study group: 7.5 mo for LDAC arm and not reached for AZA arm; median EFS has not been reached for either arm (Figure). Treatment emergent grade 3/4 toxicities irrespective of attribution include hypokalemia (15), hypotension (7), hypophosphatemia (7), hyponatremia (7), hypocalcemia (7), hyperbilirubinemia (1), elevated ALT (5), hypernatremia (2) hyperglycemia (1), QTcF prolongation (1, grade 3). Conclusion: Combination of quizartinib and AZA or LDAC is highly active among patients with AML/MDS/CMML with FLT3-ITD mutation in absence of D835 mutation. Response rates appear higher than expected with either agent alone. Clinically significant QTcF prolongation is infrequent. Accrual to the study continues. Figure Figure.

5039 Background: Combined mTOR and VEGF blockade is a potentially promising and rational strategy for the treatment of advanced RCC. We previously reported the phase I safety and efficacy results of CCI 779 (C) +bevacizumab (B) n RTKI naïve stage IV RCC patients (pts) (J Clin Oncol. 2007;25[18S Suppl]:5034). We now report the interim results of the phase 2 study of C+B in RTKI refractory RCC patients. Methods: Design: Open label, phase I/II study of C+B in advanced RCC pts. Patients with measurable stage IV RCC with a component of clear/conventional cell type, performance status 0–2 and good organ function were eligible. Up to two prior treatment regimens were allowed (at least one prior RTKI). Phase II dose was C = 25 mg IV weekly and B = 10 mg/kg every 2 weeks repeated in 4 week cycles. The primary objective of the phase II portion was to assess the proportion of patients who were progression-free 6 months after study entry. Secondary objectives were assessment of response rates and toxicity. Accrual goal = 40 pts. Results: Thirty-five pts have been enrolled into the phase 2 portion to date with 4 pts ineligible. Twenty-five pts are evaluable for response assessment and 29 pts are evaluable for toxicity. Baseline characteristics (N: 35): M/F: 28/7; Number of met. sites: 1/2/3+: 15/9/11; prior nephrectomy: 31; Number of prior therapies: 1 = 29; 2 = 2. Most common (>5%) Gr 3–4 AEs (N = 29) included fatigue (6), hypercholesterolemia (2), hypertriglyceridemia (2), anorexia (2), rash (2), and anemia (2). Responses were: PR/SD/PD = 4 (16%)/18 (72%)/3 (12%). Median number of cycles administered was 4. Six month progression free rates will mature by may 2009. Conclusions: C+B combination at the recommended phase 2 doses is feasible and well tolerated. Clinical benefit rates (PR/SD) in RTKI refractory RCC patients (88%) are encouraging. Data on 6 month progression-free rates are expected to mature in 4/09. Updated data on safety, response rates, and 6-month progression free rates will be presented on all evaluable patients. Correlative studies on available plasma, serum and tumor samples for angiogenic and molecular biomarkers are underway. Supported by N01-CM62205, R21 CA 119545–02, and Commonwealth Foundation.

10516 Background: PVNS, also known as tenosynovial giant cell tumor (TGCT), is a rare pathological entity affecting the synovium in young adults. This neoplastic disease is driven by a t(1;2) translocation resulting in the fusion of COL6A3 and M-CSF genes. Nilotinib has inhibitory properties on M-CSF receptor pathway which could be of therapeutic interest in patient (pts) with non resectable PVNS. Methods: In this open-label international, multicentric, non-randomized, phase II study the primary objective is to evaluate the efficacy of nilotinib treatment (800 mg/day) in pts with progressive or relapsing PVNS not amenable to surgery or in whom surgery would be mutilating, as measured by the 12-week progression-free rate (12-w PFR) validated by an independent committee. Using a Bayesian design with a futility stopping rule and a maximum sample size set to 50 evaluable pts, interim analyses (IA) were planned after the inclusion of 10 and then every 5 pts. Results: From December 2010 to September 2012, 56 pts with progressive disease were enrolled by 17 institutions from Europe and Australia. Successive previous IA led to positive results in favour of the study continuation. 47 pts (median age 37 y (range: 18-74), 51% of males) were evaluable at the time of the last IA, with a median follow-up of 11.2 months (range: 0.6-12.7). Median time since diagnosis was 2.5 years (range: 0.02-26). Primary tumour was mainly located on knee (25 pts, 53%), hip (6 pts, 13%), ankle (6 pts, 13%). 4 pts had already received imatinib, 76% of pts had undergone a previous surgery. The 12-w PFR was 93.6% (95%CI, 82.5%-98.7%), without any OR. PR were observed later (2 at w-24 and 1 at w-48). Nilotinib was well tolerated, with only 4 pts experiencing grade 3 adverse events (anorexia: 1 pt; prurit: 1 pt; diarrhea: 1 pt; hepatic failure: 1 pt). 8 pts (17%) had a dose reduction and/or temporary discontinuation of nilotinib due to toxicity. Final results will be further presented. Conclusions: Nilotinib treatment induces disease stabilisation in a large proportion of PVNS patients with non resectable disease or in whom resection would be mutilating. Clinical trial information: NCT01261429.

132 Background: The aim of this phase I/II study was to evaluate the efficacy and safety of the combined use of docetaxel, cisplatin (CDDP) and 5-fluorouracil (5-FU) (DCF) in patients with recurrent/metastatic squamous cell carcinoma of the esophagus (SCCE). This study adopted divided doses of docetaxel and CDDP in order to reduce the toxicities of the treatment. Methods: The dose of docetaxel was escalated using the following protocol in the phase I stage: level 1, 30; level 2, 35 and level 3, 40 mg/m2, which was intravenously infused for two hours on days 1 and 8. CDDP was administered at a dose of 12 mg/m2 infused for four hours on days 1-5. The 5-FU was administered at a dose of 600 mg/m2continuously infused from day 1 to 5. This regimen was repeated every four weeks. Results: The study subjects were nine patients (phase I) and 48 patients (phase II). The recommended dose was determined as level 3 in phase I. In the phase II stage, the overall response rate was 62.5%, with a complete response rate of 12.5%. The median progression-free survival was six months, and the median overall survival was 13 months. Grade 3/4 toxicities of leukopenia, neutropenia and febrile neutropenia occurred in 64.6, 68.8 and 14.6% of the patients, while grade 3/4 non-hematological toxicities were relatively rare. No treatment-related death was recorded. Conclusions: This modified DCF regimen can be a tolerable definitive chemotherapy for unresectable SCCE because of its high efficacy, although adequate care for severe neutropenia is needed. Clinical trial information: NCT00915850.

TPS471 Background: Metastatic pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis. Recent advances with fluorouracil in combination with oxaliplatin and irinotecan (FOLFIRINOX) and nab-paclitaxel combined with gemcitabine (AG) have improved survival in patients with PDAC. A fluorouracil-based regimen is recommended for patients who progress after a gemcitabine-based regimen. Tosedostat is an oral aminopeptidase inhibitor shown to have anti-proliferative effects in malignancies. Aminopeptidase inhibitors disrupt the cleavage of amino acids from peptides downstream of proteasomal degradation, preventing the recycling of amino acids needed for new protein synthesis. This leads to intracellular depletion of amino acids, resulting in a cellular stress response known as the amino acid deprivation response, which leads to apoptosis. Because pancreatic cancer cells frequently upregulate expression of these aminopeptidases, aminopeptidases inhibitors hold therapeutic promise. Methods: This is a single institution phase I/II open-label trial to evaluate the safety and tolerability of tosedostat plus capecitabine in patients with metastatic PDAC that have progressed after a gemcitabine-based regimen. The phase I part will be conducted in a dose de-escalation fashion, with two planned dose levels of tosedostat (120mg or 60mg) p.o. daily on days 1 to 21 with capecitabine 1000 mg/m2 p.o. BID on days 1 to 14 of a 21-day cycle. If more than one patient in the tosedostat (120 mg) cohort experiences a dose limiting toxicity (DLT), then 6 more patient will be enrolled to the tosedostat (60 mg) cohort. A total of 36 patients will be enrolled in the phase II portion. Primary objective of the phase I portion is to determine the maximum tolerated dose and DLTs of tosedostat and capecitabine combination therapy. Primary objective of the phase II portion is to determine the progression-free survival at 3 months. Secondary objectives are to determine the overall response rate, time-to-progression, overall survival and CA 19-9 response. Exploratory objectives are to explore the predictive molecular biomarkers for treatment response and to explore the prognostic biomarkers. Clinical trial: NCT02352831.

Endpoint Data

4513 Background: Sunitinib is an antiangiogenic agent indicated for the treatment of metastatic renal cell carcinoma (mRCC). Sunitinib is given in a 4 week on, 2 week off (4/2) schedule. Significant toxicities are observed in patients in the 3rd and 4th weeks of therapy. We hypothesized that a 2 week on, 1 week off (2/1) schedule would provide improved toxicity without compromising efficacy. Methods: A multicenter, single arm study was performed, with patients initiating sunitinib 50mg on a 2/1 schedule. Schedule and dose alterations were performed if grade > 3 toxicities were observed. The primary objective was to determine the percentage of patients who experienced grade > 3 fatigue, diarrhea, or HFS. The sample size of 60 patients was selected to ensure the upper bound of a 95% confidence would fall below standard schedule rate of 25%-30% if sample rate was 10%-15%, respectively. Secondary outcomes included response rate (RR), progression free survival (PFS) and dose reductions. Results: Between August 2014 and April 2016, 60 patients were enrolled, and 59 treated. Patients had a median age of 65.5 years (ranging from 45-92). 24% of patients (14/59) had grade 3 or higher fatigue, diarrhea, or HFS (95% CI: 13.6%, 36.6%). This is similar to the average of the 4 week on, 2 week off schedule of 25%-30%, and the lower bound of the confidence interval is in the center of our target rate of 10%-15%. Among events at least possibly related to study drug, patients were most likely to experience the expected events of diarrhea (75% with 5 grade 3 events), fatigue (71% with 6 grade 3 events), and HFS (54% with 3 grade 3 events). 22 (37%) patients responded (25.0%, 50.9%). Among patients with secondary endpoint data available, median PFS was 19.3 months (95% CI: 8.2, NR) and 33/56 (59%) of patients underwent dose reduction. Conclusions: Sunitinib administered in a 2/1 schedule in this study did not result in a lower rate of grade 3 or higher fatigue, diarrhea or HFS when compared to historical data from trials employing a 4/2 schedule. However, efficacy data showed robust response rate and a prolonged PFS, suggestive of long-term tolerability in patients receiving sunitinib on a 2/1 schedule. Evaluation of toxicity kinetics and patient quality of life is ongoing. Clinical trial information: NCT02060370.

Line Of Therapy

4503 Background: Pembrolizumab (P), a PD-1 inhibitor, is active and well tolerated in platinum-treated, advanced urothelial carcinoma (UC). Epacadostat (E) potently and selectively inhibits indoleamine 2,3-dioxygenase 1 (IDO1), a tryptophan-catabolizing enzyme that suppresses T-cell–mediated immune surveillance. IDO1 overexpression is associated with tumor progression and shortened patient (pt) survival. ECHO-202/KEYNOTE-037 is an open-label, phase I/II study of E + P in pts with advanced tumors. We report phase I/II efficacy and safety outcomes for the UC cohort at an October 29, 2016 data cutoff. Methods: Adult pts with advanced UC, prior platinum therapy (adjuvant or advanced disease setting) or alternative therapy (if platinum was not appropriate), and no prior checkpoint inhibitor therapy were eligible to participate. In phase I, pts received E (25, 50, 100, or 300 mg PO BID) + P (2 mg/kg or 200 mg IV Q3W); MTD was not exceeded. E (100 mg BID) + P (200 mg Q3W) dosing was selected for phase II. Response was assessed in RECIST 1.1–evaluable pts. Safety was assessed in pts receiving ≥1 E + P dose. Results: A total of 40 pts (phase I, n = 5; phase II, n = 35) were evaluated. Median age was 67 years, 75% were men, 88% were white, 100% had prior platinum therapy, and 75% had 0–1 prior line of therapy for advanced disease. Preliminary ORR (CR+PR) and DCR (CR+PR+SD) for all efficacy-evaluable pts were 35% (13/37; all PR) and 57% (21/37; 13 PR, 8 SD), respectively; for pts with 0–1 prior line of therapy for advanced disease, ORR and DCR were 37% (10/27) and 63% (17/27). At data cutoff, 12/13 responses were ongoing (range, 1+ to 652+ days). PFS and biomarker analyses are ongoing. The most common TRAEs (≥10% of 40 pts) were fatigue (28%), rash (18%), and increased amylase (10%; asymptomatic). Grade ≥3 TRAEs occurred in 20% of pts (rash was the only grade ≥3 TRAE to occur in > 1 pt [n = 3]). Three pts discontinued due to TRAEs (grade 3 rash [n = 1]; grade 3 COPD exacerbation [n = 1], grade 2 diarrhea [n = 1]). Conclusions: E + P was generally well tolerated and associated with increased response compared with previously reported PD-1 inhibitor monotherapy in pts with advanced UC. A phase III UC study is planned. Clinical trial information: NCT02178722.
