e13020 Background: Patients with advanced cholangiocarcinoma (CC) and gallbladder carcinoma (GC) have few effective therapeutic options. We compared prognostic factors and clinical outcomes of CC/GC pts treated on phase I trials with that of their first-, second-line and last Food and Drug Administration (FDA)-approved therapy given in setting of metastatic disease. Methods: We retrospectively reviewed electronic medical records of patients with GC and CC evaluated in the phase I program clinic from November 2004 to March 2011. Results: Of the 72 patients with CC or GC, 32 (44%) were not enrolled on a trial mainly due to clinical deterioration (n=25). Of 40 treated patients (GC=6; CC=34; median age 60 years; median prior systemic therapies = 3), 8 (20%) had stable disease (SD) > 6 months; 3 (8%) achieved a partial response (PR); SD > 6 months/PR was observed mainly on protocols with hepatic arterial infusion drug administration and/or angiogenic inhibitors, anti-her2/neu agents or a novel MAPK/ERK kinase (MEK) inhibitor. Median progression-free survival (PFS) on phase I trials was 2.0 months (95% CI 1.7, 2.8) versus 3.0 months (95% CI 2.4, 5.0; p=0.95), 3.0 months (95% CI 2.3, 4.6; p=0.98), and 3.0 months (95% CI 2.4, 3.9; p=0.79) for their first-, second-, and last systemic therapy with FDA-approved agents given in the metastatic setting, respectively. In univariate analysis, factors associated with a shorter Phase I PFS were > 3 metastatic sites, elevated ALT (>56 IU/L), serum creatinine (>1.6mg/dL), and CA19-9 (>35U/mL). Conclusions: In heavily pretreated patients, PFS in the clinical trials setting remained poor but did not differ significantly from that of their first-line, second-line, and last prior therapy with FDA-approved agents. Response rate (SD >6 months/PR) of 28% was seen in trials with locoregional treatment or inhibitors of angiogenesis, her2/neu or MEK.

Abstract BACKGROUND: In newly diagnosed patients, the addition of thalidomide or bortezomib (Velcade™) to the standard oral melphalan/prednisone combination significantly increased response rate and event-free survival. In this multicenter, open-label, non randomized, phase I/II trial, the safety/efficacy profile of the 4 drug combination, bortezomib (Velcade™), melphalan, prednisone, and thalidomide (VMPT) was evaluated in patients with relapsed/refractory myeloma. METHODS: Bortezomib was administered by IV bolus on days 1, 4, 15, 22 at three dose levels: in the first cohort (10 patients) at 1.0 mg/m2; in the second cohort (10 patients) at 1.3 mg/m2and in the third cohort (10 patients) at 1.6 mg/m2. Oral melphalan was administered at 6 mg/m2 on days 1–5, oral prednisone at 60 mg/m2 on days 1–5. Thalidomide was delivered at 50 mg on days 1–35. Each course was repeated every 35 days for a total of 6 courses. RESULTS: Thirty patients, median age 66 years (range 38–79), with relapsed or refractory myeloma were enrolled. Fourteen patients received VMPT as second line of therapy, 16 as third line. Twenty patients received prior autologous transplant, 10 conventional chemotherapy and 9 thalidomide-based regimens. After a median of 6 courses, 20 patients (67%) achieved a partial response (PR) including 13 patients (43%) who achieved at least a very good partial response (VGPR). Among patients who received VMPT as second line treatment, the PR rate was 79%, and the immunofixation negative complete response rate 36%. The 1-year progression-free survival was 61%, and the 1-year survival from study entry was 84%. Grade 3 non-hematological adverse events included: infections (5 patients), fatigue (1), vasculitis (1) and peripheral neuropathy (2); no grade 4 toxicities were recorded. CONCLUSIONS: Initial results showed that VMPT is an effective salvage therapy with a high proportion of responses. Toxicities were manageable. The incidence of neurotoxicities was unexpectedly low.

591 Background: FOLFOX+bevacizumab (BEV) is the standard systemic chemotherapy for metastatic colorectal cancer (CRC). We investigated the combination of FOLFOX4 and hepatic arterial infusion (HAI) in patients who had isolated liver metastasis from CRC. We also compared efficacy and safety between this combination therapy and its concomitant use with BEV. Methods: Twenty-five patients entered a phase I/II trial of HAI (5-FU 250 mg/d, leucovorin 25 mg/d; d1-7, q2w) combined with FOLFOX4. Fourteen other patients with a similar background received HAI + FOLFOX4 combined with BEV and the two regimens were compared. Results: In the phase I/II study, the recommended doses for FOLFOX were as follows: L-OHP, 85 mg/m2; l-LV, 100 mg/m2; 5-FU (bolus), 400 mg/m2; and 5-FU (infusion), 600 mg/m2. Sixteen patients who received this regimen showed a response rate of 93.8% (2 CR and 13 PR), a median progression-free survival of 323 days, and a one-year survival rate of 93.7%. In the subsequent phase II trial of HAI + FOLFOX4 with BEV, 14 patients were enrolled and the response rate was 78.6% (2 CR and 9 PR). The outcome was inferior when BEV was used concomitantly. The median numbers of doses were 10 (range: 1-27) for FOLFOX4 and 9 (1-27) for HAI without BEV, whereas the corresponding numbers with BEV were 8 (1-12) and 2 (0-9), respectively. There was a marked decrease in the number of HAI procedures when BEV was used. Thrombosis occurred in 8 patients who received concomitant BEV, which was the most common reason for cessation of HAI. Other adverse events (≥Grade 3) were neutropenia (n=7; 43.8%) and thrombocytopenia (n=2; 12.5%) without BEV or neutropenia (n=7; 43.8%) and diarrhea (n=1; 7.1%) with BEV, and no marked difference was seen between the two regimens. Both regimens were well tolerated. Severe neuropathy was only observed in 1 patient (6.3%; Grade 3) who received concomitant BEV. Conclusions: In the present study, HAI + FOLFOX combined with BEV caused thrombosis and disturbance of wound healing, thereby increasing the incidence of complications and making it difficult to continue treatment. These findings suggest that BEV should not be administered with HAI therapy. No significant financial relationships to disclose.

588 Background: Most cholangiocarcinoma (CCA) patients (pts) are diagnosed with advanced disease and are ineligible for surgery. FGFR2 fusions or rearrangements are present in 10–16% of pts with intrahepatic CCA (iCCA) and are reported to be oncogenic drivers. However, little data are available on the role of FGFR2 genetic alterations in the response to systemic cancer therapy. FIGHT-202 is a phase 2 study of pemigatinib (a selective, potent, oral FGFR1–3 inhibitor) in pts with previously treated advanced/metastatic CCA (NCT02924376); primary results were reported at ESMO 2019. FIGHT-202 enrolled pts who progressed on ≥1 prior therapy, allowing the examination of the role of FGFR2 alterations on the response to prior therapy. The objective of this post hoc analysis was to evaluate progression free survival (PFS) on standard systemic therapy received prior to study enrollment among pts with CCA harboring FGFR2 fusions or rearrangements ( FGFR2+). Methods: Case report forms were reviewed to determine disease history and exposure to prior lines of systemic cancer therapies (LOSCT) in the advanced setting before receiving pemigatinib. Only pts with sufficient data on prior LOSCT were included in this analysis. Median PFS was calculated using the Kaplan-Meier method. Results: 102 pts were included in this analysis (median age 54.5, 61.8% female). Median PFS on first-line therapy was 5.5 (95% CI: 4.0, 8.0) months. Among the 38 pts (37.3%) with ≥2 prior LOSCT, median PFS on second-line therapy was 4.4 (95% CI: 3.0, 5.3) months. Conclusions: This analysis provides data about PFS on standard systemic therapies for pts with FGFR2+ CCA. Median PFS on first-line therapy was lower than historical published data, and median PFS on second-line therapy was slightly longer than previously reported, in unselected CCA populations. Limitations of this analysis include retrospective examination of investigator reported data, and that clinical trial participants may not truly reflect a general CCA patient population. The short PFS on standard therapies in pts with FGFR2+ CCA highlights the need for development of other options including targeted therapies to improve outcomes.

10607 Background: p53 mutation is one of the most common mutations in human tumors and plays an important role in apoptosis, genomic stability and inhibition of angiogenesis. Methods: We retrospectively reviewed 121 consecutive patients (pts) with solid tumors referred to the Clinical Center for Targeted Therapy (Phase I program) who were tested for p53 mutation, and compared clinical characteristics and outcomes in p53 positive vs. wild-type (wt) pts. Results: Of the 121 tested pts, 65 (53.7%) were p53 mutation-positive. The presence of p53 mutation was not associated with sex and race. Tumors with p53 mutation metastasized more often to the liver (44 pts (67.7%) with mutated p53 vs. 26 pts (46.4%) with wt p53, p=0.0264); there was no difference in metastasis to the bones, lungs, brain, soft tissues and adrenals. p53 mutation also showed a trend toward an association with PTEN-loss (13 out of 43 (30%) with p53 mutated vs. 4 out of 37 (11%) with wt p53, p=0.053). Among pts with the p53 mutation, the best median progression-free survival (PFS) prior to phase I trial entry was 10.97 months (range 0.85–29.04 months) when the treatment regimen included bevacizumab and 4.37 months (range 0.92–14.98 months) when the treatment did not include bevacizumab (P=0.0046). Among patients with wt p53, there was no significant difference in PFS between bavacizumab-containing regimens and regimens without bevacizumab. The median OS from diagnosis was 7.7 years (95% CI 6.32–9.84 years) vs. 11.8 years (95% CI 10.37 years, not attained) for p53 mutant vs. wild-type disease (p = 0.03). Univariate analysis for OS from diagnosis showed that mutated p53, Hispanic race (vs. Caucasians) and the shorter time from diagnosis to metastasis were associated with a worse prognosis. Conclusions: Tumors with p53 mutation have a more aggressive clinical behavior, metastasize more to the liver and may have a higher rate of PTEN loss compared to tumors with wt p53; In addition, anti-angiogenic agents may be of therapeutic value in p53-mutated pts.

354 Background: Axitinib is a potent and selective second-generation inhibitor of vascular endothelial growth factor receptors (VEGFRs) 1, 2, and 3. In the phase 3 AXIS trial of axitinib vs sorafenib for second-line mRCC, axitinib significantly prolonged median progression-free survival (mPFS) (6.7 vs 4.7 months; hazard ratio 0.665; P<0.0001). Here, we evaluated the effect of prior sunitinib treatment duration and axitinib dose titration on subsequent axitinib efficacy. Methods: Eligible patients had clear-cell mRCC; measurable RECIST-defined progressive disease after 1 prior first-line systemic therapy; and Eastern Cooperative Oncology performance status (PS) 0/1. Patients were stratified by PS and prior therapy, and randomized 1:1 to either axitinib, at a starting dose of 5 mg twice daily (BID), or sorafenib, 400 mg BID. Patients without toxicity >grade 2 and BP <150/90 mmHg without antihypertensive medication for >2 weeks were eligible to increase axitinib dose to 7 mg BID and then to 10 mg BID. Results: The mPFS for patients receiving at least one total daily axitinib dose >10 mg (dose-titrated group; n=132) was 6.6 months [95% CI 4.7–8.3] and 8.3 months [95% CI 6.0–10.2] for patients receiving axitinib ≤10 mg (n=227). A total of 194 patients (53.7%) in the axitinib arm and 195 patients (53.9%) in the sorafenib arm had prior sunitinib treatment. The mPFS for patients with duration of prior sunitinib treatment ≥6 months and <6 months were 4.8 months [95% CI 4.5–6.5] and 4.6 months [95% CI 2.8–8.3] for axitinib patients; and 4.6 months [95% CI 2.9–4.9] and 2.9 months [95% CI 2.8–4.6), for sorafenib patients. The mPFS for duration of prior sunitinib ≥9 months and <9 months were 6.3 months [95% CI 4.6–6.7] and 4.5 months [95% CI 2.8–6.4] for axitinib patients; and 4.6 months [95% CI 2.8–4.9] and 2.9 months [95% CI 2.8–4.7]) for sorafenib patients. Conclusions: Duration of prior sunitinib ≥9 months may be associated with a longer PFS on second-line VEGFR tyrosine kinase inhibitors. Both axitinib dose-increased and non-increased patients had longer PFS compared with the sorafenib arm.

6618 Background: Despite the growing number of clinical trials conducted in Asia and the unique pt demographic and molecular profile of endemic cancers, there is still lacking of studies examining the outcomes of pts on PIT. We examined the characteristics and outcomes of pts enrolled in phase I trials in National Cancer Center Singapore (NCCS). Methods: We reviewed 296 pts enrolled in PIT from 2004-2012 to identify factors that predicted for 90-day mortality and OS. Logistic regression model and Cox proportional hazard model assessed factors associated with 90DM and OS, respectively. The discriminative ability of the RMH prognostic score (LDH, no of met sites, albumin) and the final multivariate Cox model derived in Asian pts was evaluated using Harrell’s concordance index (c-index), and that for the logistic model was based on area under ROC curve (AUC). Internal validation was performed based on simulated data via bootstrapping. Results: Median age 60 (23-85), M:F (65/35%). The commonest cancer type thoracic (56%), GI (24%), head and neck (12%). 57% pt had comorbidities, commonest diabetes (16.6%) and hepatitis B (11.1%). Median no of lines of treatment 2. 20% of pts had known mut status. 15% pts survived less than 90 days from start of trial. Median OS was 9.6 m (95CI 7.8-11.2 m). Based on the RMH prognostic model, pts with score of 0 to 1 had a superior OS (median OS = 12.9 m) compared to those with score of 2 to 3 (OS = 5.7 m) (p < 0.001). The c-index for the RMH prognostic score was 0.64. On univariate analysis, alb<35,LDH>ULN, ≥3 met sites, low BMI, ECOG>0, Na<135,plt>440, Hb<12 and ≥3 lines of chemo were negative prognostic factors. On multivariate analysis, reduced model selection techniques identified alb<35, LDH>ULN, ≥3 met sites, and ≥ 3 prior lines of chemo as independent negative predictors of OS with a bias-corrected of 0.69. For 90DM, we developed a risk normogram based on ECOG, WBC, Na and Hb as continuous predictors with bias-corrected AUC 0.78. Conclusions: We have developed a novel NCCS normogram to predict for 90DM for PIT. The RMH prognostic score can be improved upon with the addition of number of prior lines of chemotherapy, underscoring the importance of early access to phase I trials.

Phase I Studies

e13550 Background: Phase I studies are a fundamental step in anti-cancer drug development. Prior meta-analysis looking at phase I studies showed an overall response rate (ORR) of 10.6 % and grade 4 toxicity rate of 14.3 %, and specifically, patients (pts) with mCRC enrolled in phase I trials had an ORR of 1.3 %. Herein, we report the results of a 12-year experience from our institution. Methods: Records from pts with metastatic colorectal adenocarcinoma enrolled in phase I studies at our institution from January 1999 to December 2010 were reviewed. Recorded data included treatment related responses, survival times and adverse events (AE). Kaplan-Meier analysis, t-test and X2 tests were used to analyze data. A Cox proportional-hazard model using clinical parameters at enrolment was used to predict survival. Results: Our cohort included 141 pts with mCRC (83% colon and 17% rectum) enrolled in 25 unique phase I trials. Median patient age at enrolment was 59 years, 66% were female and 81% had an ECOG PS of 0-1. Pts received a median of 3 lines of chemotherapy prior to enrolment. The median overall survival (OS) was 8.9 months. The ORR was 4.2%. The clinical benefit rate (ORR or stable disease for ≥ 4 months) was 22%. Univariate analysis showed that being female (P=0.02), Hb <12 g/dL (P=0.01), Alb < 4 g/dL (P=<0.001), Alkaline phosphatase > 150 U/L (P=<0.001) and LDH ≥ 300 U/L (P=<0.001) were independently associated with shorter survival. Multivariate analysis showed that females (HR of 2.81 95% CI 1.71-4.59, p= <0.001), Hb ≥ 12 g/dL (1.67, 95%CI 1.03-1.71, p=0.04), Alb < 4 g/dL (HR 2.51, 95% CI 1.59-3.98, p= <0.001) and LDH ≥300 U/L (HR 2.59, 95% CI 1.65-4.03, p= <0.001) were associated with shorter survival. Grade 3/4 non-hematological and hematological AE were seen in 25% and 45% of patients, respectively. Conclusions: This cohort of pts that received a median of 3 prior lines of therapy had a median OS and ORR of 8.9 months and 4.2%, respectively. These findings are similar to the ones reported in the recent phase III trial using regorafenib. Interestingly, multivariate analysis showed that a Hb of ≥ 12g/dL was associated with worse survival, in agreement with prior reports in which red cell growth factors were used.
