465 Background: Prospective studies with sunitinib in mRCC have shown median progression-free survival (mPFS) of 11 months (first line) and 8.3 months (second line). In order to identify patients with LTB with SU, we describe the clinical characteristics of patients with mRCC treated with SU with an mPFS of 15 months or more. Methods: This is a retrospective chart review of patients with mRCC treated with SU in two hospitals, Alexander Fleming Institute Buenos Aires in Argentina and Hospital Israelita Albert Einstein in Sao Paulo, Brazil. Inclusion criteria included patients treated with SU who had a PFS of at least 15 months. Results: Between September 1995 and August 2009, 29 cases were identified. Patient demographics were: median age of 56 years, 65% male, 96% with previous nephrectomy, Eastern Cooperative Oncology Group performance status (PS) of either 0 (52%) or 1 (48%), 93% had clear cell histology, 69% received prior systemic therapy, and 78% had ≤ 2 metastatic sites (mostly in the lungs, liver and bone). Patients were started on SU 50 mg 4 weeks on treatment/2 weeks off treatment (4/2) (n=26) or 37.5 mg 6 weeks continuous dosing (n=3). For those patients starting on 4/2, dose reduction was necessary in 59% of the patients to maintain SU therapy. Median duration of therapy was 23.7 months. During treatment, 24 patients (83%) developed hypertension. Response rates were as follows: complete response 7% (n=2), partial response 38% (n=11), stable disease 52% (n=15); data missing for one patient. Conclusions: LTB is seen in patients who are young, have good performance status, and either 1 or 2 metastatic sites. Dose reductions are common in order to maintain treatment while benefiting from SU. Treatment with SU as either first- or second-line therapy did not appear to influence outcome. Hypertension is a common finding and serves as a predictive marker during treatment, but study limitations preclude the identification of pre-treatment predictive factors.

Patients treated with dabrafenib/trametinib (DAB/TRA) exhibit a large interindividual variability in clinical outcomes. The aims of this study were to characterize the pharmacokinetics of DAB, hydroxy-dabrafenib (OHD), and TRA in BRAF-mutated patients and to investigate the exposure–response relationship for toxicity and efficacy in metastatic melanoma (MM) patients. Univariate Fisher and Wilcoxon models including drug systemic exposure (area under the plasma concentration curve, AUC) were used to identify prognostic factors for the onset of dose-limiting toxicities (DLT), and Cox models for overall (OS) and progression-free survival (PFS). Seventy-three BRAF-mutated patients were included in pharmacokinetic (n = 424, NONMEM) and 52 in pharmacokinetic/pharmacodynamic analyses. Age and sex were identified as determinants of DAB and OHD clearances (p < 0.01). MM patients experiencing DLT were overexposed to DAB compared to patients without DLT (AUC: 9624 vs. 7485 ng∙h/mL, respectively, p < 0.01). Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≥ 2 and plasma ratio AUCOHD/AUCDAB ≥ 1 were independently associated with shorter OS (HR: 6.58 (1.29–33.56); p = 0.023 and 10.61 (2.34–48.15), p = 0.022, respectively). A number of metastatic sites ≥3 and cerebral metastases were associated with shorter PFS (HR = 3.25 (1.11–9.50); p = 0.032 and HR = 1.23 (1.35–10.39), p = 0.011; respectively). TRA plasma exposure was neither associated with toxicity nor efficacy. Our results suggest that early drug monitoring could be helpful to prevent the onset of DLT in MM patients, especially in fragile patients such as the elderly. Regarding efficacy, the clinical benefit to monitor plasma ratio AUCOHD/AUCDAB deserves more investigation in a larger cohort of MM patients.

451 Background: Gemcitabine plus platinum (GP) is the standard of care first-line treatment for advanced biliary tract cancers (BTC). There is no established second-line therapy, and retrospective reviews report progression-free survival (PFS) for second-line treatment to be < 3 months. 5-Fluorouracil plus irinotecan (FOLFIRI) is a commonly used regimen in patients (pts) with BTC who have progressed on GP, though there is a paucity of data regarding its efficacy in this population. Methods: We retrospectively evaluated pts with advanced BTC who were treated with FOLFIRI at MD Anderson, University of Michigan and Mayo Clinic in Jacksonville. Data were obtained on pt demographics, type of BTC, PFS, and overall survival (OS). Results: Ninety-eight pts were included of which 74 (76%) had metastatic disease at the time of treatment with FOLFIRI. The median age was 59 (range, 22 to 86) years. The number of pts with extrahepatic cholangiocarcinoma (CCA)/gall bladder (GB)/intrahepatic CCA were 10, 17, and 71. FOLFIRI was used as 1st, 2nd, 3rd or 4th – Nth lines in 8, 50, 36, and 4 pts, respectively. Of the 65 pts whose best responses were documented, 23 (35%) had stable disease and 7 (11%) had a partial response per RECIST v1.1. Median duration on FOLFIRI was 2.2 months. The median PFS and OS were 2.4 (95% CI 1.7 to 3.1) and 6.6 (95% CI 4.7 to 8.4) months, respectively. Median PFS for pts treated with FOLFIRI in 1st, 2nd, 3rd or 4th – Nth lines were 3.1, 2.5, 2.3 and 1.5 months, respectively. Eighteen pts received concurrent bevacizumab (13) or EGFR-targeted therapy (5) with FOLFIRI, and both of groups exhibited a median PFS of 2.7 months. Eastern Cooperative Oncology Group performance status (PS) of 0-1 was associated with improved OS (P = 0.006) compared to PS of 2-3. Conclusions: In this multi-institution retrospective review of 98 pts with BTC treated with FOLFIRI, efficacy of this regimen appears to be modest. While PFS and OS outcomes were similar to what has been previously reported, the 46% disease control rate in this group of predominantly pretreated pts is encouraging. Given the lack of other standard therapies, FOLFIRI may still have a role in this pt population, but these results emphasize the need for more effective treatment options for pts with advanced, pretreated BTC.

Kras Status

PurposePanitumumab is a fully human anti–epidermal growth factor receptor (EGFR) monoclonal antibody that improves progression-free survival (PFS) in chemotherapy-refractory metastatic colorectal cancer (mCRC). This trial evaluated the efficacy and safety of panitumumab plus fluorouracil, leucovorin, and irinotecan (FOLFIRI) compared with FOLFIRI alone after failure of initial treatment for mCRC by tumor KRAS status.Patients and MethodsPatients with mCRC, one prior chemotherapy regimen for mCRC, Eastern Cooperative Oncology Group performance status 0 to 2, and available tumor tissue for biomarker testing were randomly assigned 1:1 to panitumumab 6.0 mg/kg plus FOLFIRI versus FOLFIRI every 2 weeks. The coprimary end points of PFS and overall survival (OS) were independently tested and prospectively analyzed by KRAS status.ResultsFrom June 2006 to March 2008, 1,186 patients were randomly assigned 1:1 and received treatment. KRAS status was available for 91% of patients: 597 (55%) with wild-type (WT) KRAS tumors, and 486 (45%) with mutant (MT) KRAS tumors. In the WT KRAS subpopulation, when panitumumab was added to chemotherapy, a significant improvement in PFS was observed (hazard ratio [HR] = 0.73; 95% CI, 0.59 to 0.90; P = .004); median PFS was 5.9 months for panitumumab-FOLFIRI versus 3.9 months for FOLFIRI. A nonsignificant trend toward increased OS was observed; median OS was 14.5 months versus 12.5 months, respectively (HR = 0.85, 95% CI, 0.70 to 1.04; P = .12); response rate was improved to 35% versus 10% with the addition of panitumumab. In patients with MT KRAS, there was no difference in efficacy. Adverse event rates were generally comparable across arms with the exception of known toxicities associated with anti-EGFR therapy.ConclusionPanitumumab plus FOLFIRI significantly improved PFS and is well-tolerated as second-line treatment in patients with WT KRAS mCRC.

Purpose The study objective was to determine the proportion of patients with hepatocellular carcinoma (HCC) treated with the combination of bevacizumab (B) and erlotinib (E) who were alive and progression free at 16 weeks (16-week progression-free survival [PFS16]) of continuous therapy. Secondary objectives included response rate, median PFS, survival, and toxicity. Patients and Methods Patients who had advanced HCC that was not amenable to surgical or regional therapies, up to one prior systemic treatment; Childs-Pugh score A or B liver function; Eastern Cooperative Oncology Group performance status 0, 1, or 2 received B 10 mg/kg every 14 days and E 150 mg orally daily, continuously, for 28-day cycles. Tumor response was evaluated every 2 cycles by using Response Evaluation Criteria in Solid Tumors Group criteria. A total of 40 patients were treated. Results The primary end point of PFS16 was 62.5%. Ten patients achieved a partial response for a confirmed overall response rate (intent-to-treat) of 25%. The median PFSevent was 39 weeks (95% CI, 26 to 45 weeks; 9.0 months), and the median overall survival was 68 weeks (95% CI, 48 to 78 weeks; 15.65 months). Grades 3 to 4 drug-related toxicity included fatigue (n = 8; 20%), hypertension (n = 6; 15%), diarrhea (n = 4; 10%) elevated transaminases (n = 4; 10%), gastrointestinal hemorrhage (n = 5; 12.5%), wound infection (n = 2; 5%) thrombocytopenia (n = 1; 2.5%), and proteinuria, hyperbilirubinemia, back pain, hyperkalemia, and anorexia (n = 1 each). Conclusion The combination of B + E in patients who had advanced HCC showed significant, clinically meaningful antitumor activity. B + E warrant additional evaluation in randomized controlled trials.

Phase Iii Study

Purpose A phase III study comparing eribulin with dacarbazine in patients with advanced liposarcoma (LPS) or leiomyosarcoma showed a significant improvement in overall survival (OS) for the eribulin arm, with a manageable toxicity profile. We now report the histology-specific subgroup analysis of the efficacy and safety of eribulin compared with dacarbazine in patients with LPS, an independently randomized stratified subgroup of this phase III trial. Methods Patients ≥ 18 years with advanced or metastatic dedifferentiated, myxoid/round cell, or pleomorphic LPS incurable by surgery or radiotherapy were included. Patients with Eastern Cooperative Oncology Group performance status ≤ 2 and two or more prior systemic treatment regimens, including one with anthracycline, were randomly assigned 1:1 to receive eribulin mesylate (1.4 mg/m2 intravenously on days 1 and 8) or dacarbazine (850, 1,000, or 1,200 mg/m2 intravenously on day 1) every 21 days. OS, progression-free survival (PFS), and safety were analyzed. Results In the LPS subgroup, OS was significantly improved: 15.6 versus 8.4 months (hazard ratio, 0.51; 95% CI, 0.35 to 0.75; P < .001) with eribulin versus dacarbazine, respectively. Longer OS with eribulin was observed in all LPS histologic subtypes and in all geographic regions evaluated. PFS was also improved with eribulin versus dacarbazine (2.9 v 1.7 months, respectively; hazard ratio, 0.52; 95% CI, 0.35 to 0.78; P = .0015). Adverse events were similar between arms. Conclusion In patients with previously treated LPS, eribulin was associated with significantly superior OS and PFS compared with dacarbazine. Eribulin represents an important treatment option for patients with LPS, a sarcoma subtype for which limited effective systemic treatments are available. Further studies are justified to explore the role of eribulin in earlier lines of therapy as well as in combination with other agents.

Background: Treatment with gemcitabine/nab-paclitaxel confers a survival benefit over gemcitabine monotherapy in patients with advanced pancreatic cancer (APC). However, such treatment can be associated with significant toxicities especially in older patients and carries practical disadvantages related to a weekly schedule along with financial cost. We retrospectively analyzed patients >65 years of age with APC who received a modified biweekly regimen of gemcitabine/nab-paclitaxel to evaluate efficacy and toxicity. Methods: Patients aged >65 years with chemo-naïve APC with Eastern Cooperative Oncology Group performance status ⩽2 were studied. Patients were treated with a modified regimen of gemcitabine 1000 mg/m2 and nab-paclitaxel 125 mg/m2 every 2 weeks on days 1 and 15 of a 28-day cycle. Patients were evaluated for progression-free survival (PFS) and overall survival (OS) with analyses performed using the Kaplan–Meier method. Adverse events were recorded on the day of chemotherapy. Cancer antigen 19.9 was measured in every cycle and restaging scans were performed every two cycles. Results: A total of 73 patients (median age: 73 years; range: 66–93) were treated with biweekly gemcitabine/nab-paclitaxel as first-line treatment. The median OS and PFS were 9.1 months and 4.8 months, respectively. Around 66% of patients received growth-factor support based on American Society of Clinical Oncology guidelines and no patient developed neutropenic fever. The incidences of grade ⩾3 toxicity for neutropenia, anemia, thrombocytopenia, and neurotoxicity were 2%, 7%, 3%, and 5%, respectively. Dose reductions of gemcitabine/nab-paclitaxel were required in 10% and 4% patients, respectively. Conclusion: In patients older than >65 years of age with APC, a modified regimen of biweekly gemcitabine/nab-paclitaxel was found to be effective when compared with the historical control from the MPACT study. This regimen allowed for fewer dose reductions, reduced healthcare costs from additional appointments, travel-related cost, as well as a favorable side-effect profile while maintaining efficacy. Though retrospective in nature, this study underlines the need for further investigation, particularly in elderly patients with poor performance status, such as those with pancreatic cancer, and in order to combine with a third agent, such as a targeted treatment or immunotherapy.

BackgroundNo treatment demonstrated to improve survival in patients with recurrent glioblastoma (rGB) in a randomized trial. Combining axitinib with the programmed cell death ligand 1 blocking monoclonal antibody avelumab may result in synergistic activity against rGB.MethodsAdult patients with rGB following prior surgery, radiation therapy and temozolomide chemotherapy were stratified according to their baseline use of corticosteroids. Patients with a daily dose of ≤8 mg of methylprednisolone (or equivalent) initiated treatment with axitinib (5 mg oral two times per day) plus avelumab (10 mg/kg intravenous every 2 weeks) (Cohort-1). Patients with a higher baseline corticosteroid dose initiated axitinib monotherapy; avelumab was added after 6 weeks of therapy if the corticosteroid dose could be tapered to ≤8 mg of methylprednisolone (Cohort-2). Progression-free survival at 6 months (6-m-PFS%), per immunotherapy response assessment for neuro-oncology criteria, served as the primary endpoint.ResultsBetween June 2017 and August 2018, 54 patients (27 per cohort) were enrolled and initiated study treatment (median age: 55 years; 63% male; 91% Eastern Cooperative Oncology Group Performance Status 0–1). Seventeen (63%) patients treated in Cohort-2 received at least one dose of avelumab. The 6-m-PFS% was 22.2% (95% CI 6.5% to 37.9%) and 18.5% (95% CI 3.8% to 33.2%) in Cohort-1 and Cohort-2, respectively; median overall survival was 26.6 weeks (95% CI 20.8 to 32.4) in Cohort-1 and 18.0 weeks (95% CI 12.5 to 23.5) in Cohort-2. The best objective response rate was 33.3% and 22.2% in Cohort-1 and Cohort-2, respectively, with a median duration of response of 17.9 and 19.0 weeks. The most frequent treatment-related adverse events were dysphonia (67%), lymphopenia (50%), arterial hypertension and diarrhea (both 48%). There were no grade 5 adverse events.ConclusionThe combination of avelumab plus axitinib has an acceptable toxicity profile but did not meet the prespecified threshold for activity justifying further investigation of this treatment in an unselected population of patients with rGB.

Palb2 Mutation

PURPOSE Five percent to 9% of pancreatic ductal adenocarcinomas (PDACs) develop in patients with a germline BRCA1/2 or PALB2 (g BRCA/PALB2+) mutation. Phase IB data from a trial that used cisplatin, gemcitabine, and veliparib treatment demonstrated a high response rate (RR), disease control rate (DCR), and overall survival (OS) in this population. We designed an open-label, randomized, multicenter, two-arm phase II trial to investigate cisplatin and gemcitabine with or without veliparib in g BRCA/PALB2+ PDAC. PATIENTS AND METHODS Eligible patients had untreated g BRCA/PALB2+ PDAC with measurable stage III to IV disease and Eastern Cooperative Oncology Group performance status of 0 to 1. Treatment for patients in arm A consisted of cisplatin 25 mg/m2 and gemcitabine 600 mg/m2 intravenously on days 3 and 10; treatment for patients in arm B was the same as that for patients in arm A, and arm A also received veliparib 80 mg orally twice per day on days 1 to 12 cycled every 3 weeks. The primary end point was RRs of arm A and arm B evaluated separately using a Simon two-stage design. Secondary end points were progression-free survival, DCR, OS, safety, and correlative analyses. RESULTS Fifty patients were evaluated by modified intention-to-treat analysis. The RR for arm A was 74.1% and 65.2% for arm B ( P = .55); both arms exceeded the prespecified activity threshold. DCR was 100% for arm A and 78.3% for arm B ( P = .02). Median progression-free survival was 10.1 months for arm A (95% CI, 6.7 to 11.5 months) and 9.7 months for arm B (95% CI, 4.2 to 13.6 months; P = .73). Median OS for arm A was 15.5 months (95% CI, 12.2 to 24.3 months) and 16.4 months for arm B (95% CI, 11.7 to 23.4 months; P = .6). Two-year OS rate for the entire cohort was 30.6% (95% CI, 17.8% to 44.4%), and 3-year OS rate was 17.8% (95% CI, 8.1% to 30.7%). Grade 3 to 4 hematologic toxicities for arm A versus arm B were 13 (48%) versus seven (30%) for neutropenia, 15 (55%) versus two (9%) for thrombocytopenia, and 14 (52%) versus eight (35%) for anemia. CONCLUSION Cisplatin and gemcitabine is an effective regimen in advanced g BRCA/PALB2+ PDAC. Concurrent veliparib did not improve RR. These data establish cisplatin and gemcitabine as a standard approach in g BRCA/ PALB2+ PDAC.

Background Ado-trastuzumab emtansine is an antibody-drug conjugate that combines the cytotoxic activity of emtansine with human epidermal growth factor receptor 2-targeted antitumor features of trastuzumab. Objective We conducted a study of metastatic breast cancer patients treated with trastuzumab emtansine. By evaluating progression-free survival, overall survival, and response rates, we aimed to find prognostic factors of trastuzumab emtansine treatment. Methods Our study is a single-center, retrospective, observational study. We have clinical data from 78 patients treated with trastuzumab emtansine for metastatic breast cancer, from May 2016 through May 2019, at Kartal Dr Lutfi Kirdar Education and Research Hospital, Medical Oncology Department. Our objective is to assess the survival and response rates in trastuzumab emtansine-treated individuals and the factors associated with survival. The factors we analyzed were cancer antigen 15-3 sensitivity, Eastern Cooperative Oncology Group-Performance Status, presence or absence of visceral metastases, presence or absence of cranial metastases, and treatment-associated thrombocytopenia. Results Among 78 patients, median progression-free survival was 7.8 months, and overall survival was 21.1 months. Twenty of the patients had an objective tumor response. The results showed that trastuzumab emtansine was tolerable with a manageable safety profile and consistent with the results of the previous literature. Mostly seen adverse events were anemia, thrombocytopenia, fatigue, and increased levels of alkaline phosphatase. Patients with Eastern Cooperative Oncology Group-Performance Status = 2 had worse progression-free survival and overall survival compared to ones with Eastern Cooperative Oncology Group-Performance Status < 2; progression-free survival and overall survival are worse in cancer antigen 15-3-sensitive breast cancer patients. According to our findings, treatment-associated thrombocytopenia was a significant prognostic factor for survival. Patients with thrombocytopenia had 12 months progression-free survival, whereas patients without thrombocytopenia had only 4.1 months progression-free survival. In like manner, overall survival was much better in the thrombocytopenia-experienced patients as 29.5 versus 11.8 months. Conclusions Trastuzumab emtansine prolongs progression-free survival and overall survival with a manageable safety profile. Thrombocytopenia, Eastern Cooperative Oncology Group-Performance Status, and cancer antigen 15-3 are correlated with progression-free survival and/or overall survival.

TPS477 Background: In pts with LAPC, more effective systemic therapies may be associated with improved local control, delay of metastasis, and overall survival (OS). The phase III MPACT trial in pts with metastatic PC demonstrated longer OS (median, 8.7 vs 6.6 mos; HR, 0.72; P < 0.001) and an ≈ 3-fold greater shrinkage of primary tumors with nab-P + Gem vs Gem alone (−22.15% vs −7.02%), raising the possibility of improved local PC control with nab-P + Gem. LAPACT will assess the efficacy and safety of nab-P + Gem in LAPC. Methods: LAPACT will enroll treatment-naive pts (planned n ≈ 110) in the United States, Canada, and Europe with Eastern Cooperative Oncology Group performance status ≤ 1, confirmed unresectable LAPC, no distant metastases, and adequate organ function. Pts with mixed-origin tumors, any other malignancy within 5 years, peripheral neuropathy grade > 1, or clinically significant ascites are ineligible. Pts will receive nab-P 125 mg/m2 + Gem 1000 mg/m2 on days 1, 8, and 15 of each 28-day cycle. Pts without progressive disease (PD) or unacceptable toxicity after 6 cycles will receive investigator’s choice of surgery, chemoradiotherapy, or continued nab-P + Gem. If a major response is observed, surgery may occur prior to completing 6 cycles of nab-P + Gem. The primary endpoint is time to treatment failure (TTF; time from first therapy dose to discontinuation due to PD, start of a new non–protocol-defined anti-cancer therapy, or death). The study design allows for 80% power at a 1-sided α of 0.05 to detect a 30% increase over the 5.1-month median TTF observed for nab-P + Gem in the MPACT study. The secondary endpoints are disease control rate (DCR) after 6 cycles, overall response rate, progression-free survival, OS, safety, and quality of life. The exploratory endpoint is correlation of changes in circulating nucleic acids with PD and treatment response. An interim DCR analysis will occur after all pts have completed 6 cycles of nab-P + Gem, discontinued therapy due to PD, died, or started a new non–protocol-defined therapy before completing 6 cycles of therapy. Enrollment is ongoing (first pt enrolled in April 2015). Clinical trial information: NCT02301143.
