PURPOSE To evaluate the efficacy and safety of pegvorhyaluronidase alfa (PEGPH20) plus nab-paclitaxel/gemcitabine (AG) in patients with hyaluronan-high metastatic pancreatic ductal adenocarcinoma (PDA). PATIENTS AND METHODS HALO 109-301 was a phase III, randomized, double-blind, placebo-controlled study. Patients ≥ 18 years of age with untreated, metastatic, hyaluronan-high PDA were randomly assigned 2:1 to PEGPH20 plus AG or placebo plus AG. Treatment was administered intravenously in 4-week cycles (3 weeks on, 1 week off) until progression or intolerable adverse events: PEGPH20 3.0 µg/kg twice per week for cycle 1 and once per week thereafter; nab-paclitaxel 125 mg/m2 once per week; and gemcitabine 1,000 mg/m2 once per week. The primary end point was overall survival (OS); secondary end points included progression-free survival (PFS), objective response rate (ORR), and safety. Response was independently assessed per RECIST v1.1. RESULTS At data cutoff, 494 patients were randomly assigned, with 492 (327 for PEGPH20 and 165 for placebo) included in intention-to-treat analyses. Baseline characteristics were balanced for PEGPH20 plus AG versus placebo plus AG. There were 330 deaths, with a median OS of 11.2 months for PEGPH20 plus AG versus 11.5 months for placebo plus AG (hazard ratio [HR], 1.00; 95% CI, 0.80 to 1.27; P = .97); median PFS was 7.1 months versus 7.1 months (HR, 0.97 [95% CI, 0.75 to 1.26]); ORR was 47% versus 36% (ORR ratio, 1.29 [95% CI, 1.03 to 1.63]). Grade ≥ 3 adverse events with a ≥ 2% higher rate with PEGPH20 plus AG than with placebo plus AG included fatigue (16.0% v 9.6%), muscle spasms (6.5% v 0.6%), and hyponatremia (8.0% v 3.8%). CONCLUSION The addition of PEGPH20 to AG increased the ORR but did not improve OS or PFS. The safety profile of PEGPH20 plus AG was consistent with that found in previous studies. These results do not support additional development of PEGPH20 in metastatic PDA.

8009 Background: Vandetanib is a once-daily oral inhibitor of VEGFR, EGFR and RET signaling. This phase III study compared the efficacy of vandetanib vs erlotinib in patients (pts) with advanced, previously treated NSCLC. Methods: Eligible pts (stage IIIB/IV NSCLC, PS 0–2, 1–2 prior chemotherapies; all histologies permitted) were randomized 1:1 to receive vandetanib 300 mg/day or erlotinib 150 mg/day until progression/toxicity. The primary objective was to show superiority in progression-free survival (PFS) for vandetanib vs erlotinib. Secondary endpoints included overall survival (OS), objective response rate (ORR), time to deterioration of symptoms (TDS; EORTC QoL Questionnaire) and safety. Results: Between Oct 06-Nov 07, 1240 pts (mean age 61 yrs; 38% female; 22% squamous) were randomized to receive vandetanib (n=623) or erlotinib (n=617). Baseline characteristics were similar in both arms. Median duration of follow-up was 14 months, with 88% pts progressed and 67% dead. There was no difference in PFS for pts treated with vandetanib vs erlotinib (hazard ratio [HR] 0.98, 95.22% CI 0.87–1.10; P=0.721), and no difference in the secondary endpoints of OS (HR 1.01, 95.08% CI 0.89–1.16; P=0.830), ORR (both 12%) and TDS (pain: HR 0.92, P=0.289; dyspnea: HR 1.07, P=0.407; cough: HR 0.94, P=0.455). A preplanned non-inferiority analysis for PFS and OS demonstrated equivalent efficacy for vandetanib and erlotinib. The adverse events (AEs) observed for vandetanib were generally consistent with previous NSCLC studies with vandetanib 300 mg. There was a higher incidence of some AEs (any grade) with vandetanib vs erlotinib, including diarrhea (50% vs 38%) and hypertension (16% vs 2%); rash was more frequent with erlotinib (38% vs 28%). The overall incidence of CTCAE grade ≥3 AEs was also higher with vandetanib (50% vs 40%). The incidence of protocol-defined QTc prolongation in the vandetanib arm was 5%. Conclusions: The study did not meet its primary objective of demonstrating PFS prolongation with vandetanib vs erlotinib in pts with previously treated advanced NSCLC. However, vandetanib and erlotinib showed equivalent efficacy for PFS and OS in a preplanned non-inferiority analysis. [Table: see text]

LBA7512 Background: This study evaluated whether motesanib (a selective oral inhibitor of VEGFR 1, 2 and 3; PDGFR and Kit) plus C/P improved overall survival (OS) compared with placebo + C/P in patients (pts) with nonsquamous NSCLC and in a subset of pts with adenocarcinoma. Methods: Pts had stage IIIB/IV or recurrent nonsquamous NSCLC and no prior systemic therapy for advanced NSCLC. The study initially enrolled all histologies but was amended to exclude pts with squamous NSCLC owing to a high rate of hemoptysis. Pts were randomized 1:1 to receive up to six 3-wk cycles of C (AUC 6 mg/mL·min) and P (200 mg/m2) with either motesanib 125 mg QD (Arm A) or placebo QD (Arm B) orally continuously. The primary endpoint was OS; secondary endpoints included progression-free survival (PFS), adverse events (AEs), objective response rate (ORR) and association between placental growth factor (PLGF) change and OS. OS was evaluated using a stratified Cox model and 2-sided log-rank test (α=0.03 for nonsquamous pts and α=0.02 for adenocarcinoma pts). Results: 1090 pts with nonsquamous NSCLC were randomized (Arm A/B, n=541/549); 890 had adenocarcinoma (n=448/442). 61% were men; median age was 60 years (range 21–87); 83% had stage IV disease. At the time of analysis, 753 pts had died (608 pts with adenocarcinoma). Median follow-up was 10.6 mo. OS was not significantly improved in Arm A compared with Arm B (Table). In Arm A, PLGF analysis did not show an association with OS. The incidence of grade ≥3 AEs in Arms A/B was 73/59%. Grade ≥3 AEs occurring more frequently in Arm A than B included neutropenia (22/15%), diarrhea (9/1%), hypertension (7/1%) and cholecystitis (3/0%). The incidence of grade 5 AEs was 14/9% in Arms A/B. Conclusions: In pts with advanced nonsquamous NSCLC, treatment with motesanib + C/P did not significantly improve OS compared with C/P alone.

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.

193 Background: Pancreatic ductal adenocarcinoma (PDAC) is invariably diagnosed at an advanced stage and has poor clinical outcome. Hypoxia is a significant prognostic factor in PDAC progression and is associated with poor prognosis. Evofosfamide (Evo, previously known as TH-302) is a hypoxia-activated prodrug of bromo-isophosphoramide mustard (Br-IPM) that is preferentially activated under hypoxic conditions. The addition of Evo to gemcitabine (Gem) significantly improved progression-free survival (PFS) in a randomized phase II trial in advanced PDAC (NCT01144455). Methods: MAESTRO is an international, randomized, double-blind, placebo-controlled phase III trial of Evo/Gem vs Placebo/Gem in patients (pts) with measurable, locally advanced unresectable or metastatic PDAC (NCT01746979). Evo and Gem were administered intravenously at a dose of 340 mg/m2 and 1,000 mg/m2, respectively, on days 1, 8, and 15 of a 28-day cycle. Treatment continued until disease progression. Key eligibility criteria included ECOG PS 0/1 and no neoadjuvant or adjuvant chemotherapy <6 months prior to entry. The primary endpoint was overall survival (OS) with the study designed to detect a HR of 0.75 with 90% power. Secondary endpoints included PFS and objective response rate (ORR), employing a hierarchical testing procedure with a 2-sided α=0.05 at each level. Results: A total of 693 pts were randomized to treatment with Evo/Gem (n=xxx) or Placebo/Gem (n=yyy). Baseline pt characteristics were similar between treatment arms. The OS HR was X.XX (95% CI: Y.YY, Z.ZZ; p=A.AAA). Median OS was AA.A months (m) for Evo/Gem vs BB.B m for Placebo/Gem. Median PFS was C.C m and D.D m, respectively (HR E.EE [95% CI: F.FF, G.GG; p = H.HHH). ORR was JJ.J% with Evo/Gem vs KK.K% with Placebo/Gem (p = L.LLL). Grade ≥3 adverse events (AEs) occurring in >5% of pts in treated with Evo/Gem were: TBC. Conclusions: The data from the MAESTRO trial will make an important contribution to our understanding of PDAC treatment. Clinical trial information: NCT01746979.

5508 Background: MTC arises from parafollicular cells of the thyroid gland, accounts for 5-8% of thyroid cancers and represents an unmet medical need. Cabozantinib (cabo) is an oral inhibitor of MET, VEGFR2, and RET. We conducted a phase III study of cabo vs placebo (P) in pts with progressive, unresectable, locally advanced or metastatic MTC. Methods: Eligible pts were required to have documented RECIST progression within 14 months of screening. The primary efficacy measure was progression-free survival (PFS) as assessed by an independent review facility (IRF) using RECIST. Secondary efficacy measures included objective response rate (ORR) and overall survival (OS). The study has 90% power to detect a 75% increase in PFS and 80% power to detect a 50% increase in OS. Tumor assessments occurred every 12 weeks. Crossover between treatment arms was not allowed. Results: Between Sept 2008 and Feb 2011, 330 pts (median age 55 yrs; 67% male; 96% measureable disease; RET mutation status: pos 48%; neg 12%; unknown 39%; prior TKI exposure: yes 21%, no 78%, unknown 2%) were randomized 2:1 to cabo (140 mg free base [175 mg salt form] qd; n=219) or P (n=111). The planned primary PFS analysis included events through the date of the 138th event. As of 15June2011, 44.7% of pts on cabo and 13.5% on P were still receiving study treatment. Statistically significant PFS prolongation of 7.2 mo was observed; median PFS for cabo was 11.2 mo vs 4.0 mo for P (HR 0.28, 95% CI 0.19-0.40, p<0.0001). PFS results favored the cabo group across subset analyses including RET status and prior TKI use. ORR was 28% for cabo vs 0% for P (p<0.0001). An interim analysis of OS (44% of the 217 required events) did not show a difference between cabo and P. The most frequent grade ≥3 adverse events (cabo vs P) were diarrhea (15.9 vs 1.8%), palmar-plantar erythrodysesthesia (12.6 vs 0%), fatigue (9.3 vs 2.8%), hypocalcemia (9.3 vs 0%), and hypertension (7.9 vs 0%). Conclusions: This phase III study met its primary objective of demonstrating substantial PFS prolongation with cabo vs. P in a patient population with MTC and documented progressive disease in need of therapeutic intervention.

Metastatic Pancreatic Adenocarcinoma

TPS4149 Background: Lysyl oxidase-like molecule 2 (LOXL2) is an extracellular matrix enzyme that catalyzes the covalent cross-linking of collagen and is widely expressed across desmoplastic tumors. Simtuzumab (GS-6624) is a humanized antibody that specifically inhibits LOXL2 enzymatic activity. Inhibiting LOXL2 is expected to block formation of desmoplasia, which is thought to play an important role in tumor progression and metastasis. Methods: The primary objective and of the study is to compare the additive efficacy of simtuzumab vs. placebo in combination with gemcitabine as measured by improvement in progression free survival (PFS). The secondary objective is to compare the additive efficacy of simtuzumab vs. placebo as measured by overall survival (OS) and objective response rate. Study Design: The study is a randomized, double-blind, placebo controlled Phase 2 trial in subjects with metastatic pancreatic adenocarcinoma. A total of 234 subjects will be randomized to 200 mg simtuzumab, 700 mg simtuzumab, or placebo at a 1:1:1 ratio (78 subjects per treatment group) in combination with gemcitabine in cycles of 28 days. In each cycle, subjects will receive IV GS-6624 or placebo infused on Days 1 and 15, and IV gemcitabine (1000 mg/m2) on Days 1, 8, and 15. CT or MRI scans will be performed every 8 weeks to evaluate response to treatment. Subjects will continue courses of treatment every 28 days in the absence of disease progression or unacceptable toxicity. As of January 30, 2013, 162 subjects have been randomized. Clinical trial information: NCT01472198.

BackgroundIn the KEYNOTE-022 study, pembrolizumab with dabrafenib and trametinib (triplet) improved progression-free survival (PFS) versus placebo with dabrafenib and trametinib (doublet) without reaching statistical significance. Mature results on PFS, duration of response (DOR), and overall survival (OS) are reported.MethodsThe double-blind, phase 2 part of KEYNOTE-022 enrolled patients with previously untreated BRAFV600E/K-mutated advanced melanoma from 22 sites in seven countries. Patients were randomly assigned 1:1 to intravenous pembrolizumab (200 mg every 3 weeks) or placebo plus dabrafenib (150 mg orally two times per day) and trametinib (2 mg orally one time a day). Primary endpoint was PFS. Secondary endpoints were objective response rate, DOR, and OS. Efficacy was assessed in the intention-to-treat population, and safety was assessed in all patients who received at least one dose of study drug. This analysis was not specified in the protocol.ResultsBetween November 30, 2015 and April 24, 2017, 120 patients were randomly assigned to triplet (n=60) or doublet (n=60) therapy. With 36.6 months of follow-up, median PFS was 16.9 months (95% CI 11.3 to 27.9) with triplet and 10.7 months (95% CI 7.2 to 16.8) with doublet (HR 0.53; 95% CI 0.34 to 0.83). With triplet and doublet, respectively, PFS at 24 months was 41.0% (95% CI 27.4% to 54.2%) and 16.3% (95% CI 8.1% to 27.1%); median DOR was 25.1 months (95% CI 14.1 to not reached) and 12.1 months (95% CI 6.0 to 15.7), respectively. Median OS was not reached with triplet and was 26.3 months with doublet (HR 0.64; 95% CI 0.38 to 1.06). With triplet and doublet, respectively, OS at 24 months was 63.0% (95% CI 49.4% to 73.9%) and 51.7% (95% CI 38.4% to 63.4%). Grade 3–5 treatment-related adverse events (TRAEs) occurred in 35 patients (58%, including one death) receiving triplet and 15 patients (25%) receiving doublet.ConclusionIn BRAFV600E/K-mutant advanced melanoma, pembrolizumab plus dabrafenib and trametinib substantially improved PFS, DOR, and OS with a higher incidence of TRAEs. Interpretation of these results is limited by the post hoc nature of the analysis.

LBA1 Background: The results of a phase I study in MEL suggested complementary clinical activity with NIVO (a PD-1 checkpoint inhibitor) plus IPI (a CTLA-4 checkpoint inhibitor). Here, we report the results of a randomized, double-blind, phase III trial designed to evaluate NIVO combined with IPI or NIVO alone vs IPI alone in MEL. Methods: Treatment-naïve pts (N = 945) were randomized 1:1:1 to NIVO 1 mg/kg Q2W + IPI 3 mg/kg Q3W for 4 doses followed by NIVO 3 mg/kg Q2W, NIVO 3 mg/kg Q2W + placebo, or IPI 3 mg/kg Q3W for 4 doses + placebo, until progression or unacceptable toxicity. Pts were stratified by PD-L1 status, BRAF mutation status, and M-stage. Co-primary endpoints are progression-free survival (PFS) (reported here) and overall survival (pts continue to be followed). Secondary endpoints include objective response rate (ORR) by RECIST v1.1 and safety. Results: At a minimum follow-up of 9 months, NIVO + IPI and NIVO alone significantly improved PFS and ORR vs IPI (Table). Grade 3-4 drug-related adverse events (AEs) occurred in 55.0%, 16.3%, and 27.3% of pts in the NIVO + IPI, NIVO, and IPI arms, respectively (most commonly diarrhea [9.3%, 2.2%, 6.1%], increased lipase [8.6%, 3.5%, 3.9%], increased alanine aminotransferase [8.3%, 1.3%, 1.6%], and colitis [7.7%, 0.6%, 8.7%]). Drug-related AEs led to discontinuation in 36.4%, 7.7%, and 14.8% of pts in the NIVO + IPI, NIVO, and IPI arms, with 0, 1, and 1 drug-related deaths, respectively. Efficacy outcomes by PD-L1 status will also be presented. Conclusions: NIVO + IPI and NIVO alone had superior clinical activity vs IPI alone. The results with NIVO + IPI and NIVO alone further suggest complementary activity of the two agents. There were no new safety signals or drug-related deaths observed with the combination. Clinical trial information: NCT01844505. [Table: see text]

327 Background: In the randomized, open-label, phase III KEYNOTE-426 study (NCT02853331), pembrolizumab + axitinib significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) versus sunitinib as first-line therapy for advanced RCC. Per protocol, patients could discontinue pembrolizumab or axitinib and continue the other agent. Pembrolizumab was stopped for all patients at 2 years. Axitinib could be continued until progression or toxicity. This exploratory subgroup analysis of KEYNOTE-426 describes outcomes of patients who completed 2 years of pembrolizumab. Methods: Patients included in KEYNOTE-426 were treatment naive, with clear cell RCC, KPS ≥70%, and measurable disease (RECIST v1.1). Patients were randomly assigned 1:1 to receive pembrolizumab 200 mg intravenously every 3 weeks for up to 35 doses + axitinib 5 mg orally twice daily or sunitinib 50 mg once daily (4 weeks on/2 weeks off) until progression, toxicity, or withdrawal. Primary end points of the original analysis were OS and PFS. Key secondary end points were ORR and safety. Results: Of 432 patients treated with pembrolizumab + axitinib, 129 (29.9%) completed 2 years of study therapy. Median (range) age of these patients was 61 (36-82) years, and 72.1% were male; 42 (32.6%) and 87 (67.4%) patients had International mRCC Database Consortium favorable and intermediate/poor risk, respectively, consistent with the intention-to-treat population (31.9% vs 68.1%). Median (range) follow-up (time from randomization to data cutoff) was 31.1 (24.0-37.7) months. For patients who completed 2 years of study therapy, the OS rates at 36 months was 93.8% (95% CI, 85.5%-97.4%). The PFS rates at 24 and 36 months were 72.7% (95% CI, 64.0%-79.7%) and 57.7% (95% CI, 46.3%-67.5%), respectively. The ORR was 85.3%, and the CR rate was 14.0%. 59.7% of patients experienced grade 3-5 treatment-related adverse events and 8.5% experienced grade 3-5 immune-mediated adverse events. Conclusions: In this exploratory analysis, a significant proportion of patients in the pembrolizumab + axitinib arm completed 2 years of pembrolizumab with ongoing clinical benefit.

Prognostic And Predictive Markers

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.
