TPS8053 Background: The advent of proteasome inhibitors and immunomodulatory drugs (IMiDs) have significantly improved outcomes in MM, and the first monoclonal antibodies for MM have been recently approved (daratumumab, elotuzumab). Despite novel therapies and improved disease management, MM is still considered incurable and most pts relapse, confirming the need for additional treatment options. MM cells express PD-L1, with higher levels observed after relapse and with advanced disease. Additionally, PD-L1–expressing immune cells in the microenvironment promote MM cell survival and potential immune escape. However, anti–PD-1 monotherapy did not result in objective responses in the MM cohort of a Ph I study, suggesting that MM pts need combination therapy. Daratumumab has activity as a single agent, as well as in combination with IMiDs plus dexamethasone and bortezomib plus dexamethasone in R/R MM. Immunomodulatory activity for daratumumab has also been reported. Thus, disruption of the PD-L1/PD-1 pathway may be additive or synergistic. The safety and efficacy of atezo (anti–PD-L1) alone or with lenalidomide or pomalidomide and/or daratumumab will be evaluated in a Ph Ib study of MM pts. NCT02431208. Methods: R/R MM pts with ≤ 3 prior therapies will be enrolled in Cohorts A (atezo), B (atezo + lenalidomide), D (atezo + daratumumab) and E (atezo + daratumumab + lenalidomide); MM pts with measurable disease after ASCT (Cohort C: atezo) or ≥ 3 prior therapies (Cohort F: atezo + daratumumab + pomalidomide) will also be enrolled. Cohorts B, D, E and F include a safety run-in (D) or dose escalation phase (B, E, F) and an expansion. Lenalidomide and pomalidomide will be dose escalated and the MTD evaluated in expansion phases. Atezo will be given at 1200 mg IV (A, B, C) or 840 mg IV (D, E, F); pts will get daratumumab at 16 mg/kg IV (D, E, F). All pts will be ECOG PS ≤ 2. Primary endpoints are ORR and the RP2D of lenalidomide and pomalidomide with atezo and daratumumab and the RP2D of lenalidomide with atezo. DOR and PFS are secondary endpoints; safety, PK and the relationship between biomarkers and other endpoints, including efficacy, will be assessed. Pts will be enrolled at 19 US sites. Clinical trial information: NCT02431208.

9095 Background: Despite success of single-agent immune checkpoint inhibitors, an unmet therapeutic need remains in pts with NSCLC. Chemotherapy and immunotherapy may have synergistic antitumor activity, but safety and efficacy need to be established. Here, we present interim results for pts with NSCLC (Arm C) from the phase I safety trial of nivo + nab-P in pancreatic cancer (± gemcitabine), NSCLC (+ C), and metastatic breast cancer. Methods: Part 1 evaluated potential dose-limiting toxicities (DLTs) before Part 2 expansion. Chemotherapy-naive pts with histologically/cytologically confirmed stage IIIB/IV NSCLC received 4 cycles of nab-P 100 mg/m2d 1, 8, 15 + C AUC 6 d 1 + nivo 5 mg/kg d 15 of each 21-d cycle; in cycles 5+, nivo was continued as maintenance monotherapy. Primary endpoints: number of pts with DLTs (Part 1) and percentage of pts with grade 3/4 treatment-emergent adverse events (TEAEs) or treatment discontinuation due to TEAEs (Parts 1 and 2). DLT-evaluable pts included those who received ≥ 2 complete nivo cycles and remained on study for 14 d after the last nivo dose in cycle 2, received ≥ 1 nivo dose and discontinued due to DLT before completing 2 nivo cycles, or experienced equivocal DLT after ≥ 1 nivo dose. Secondary endpoints included safety, PFS, OS, DCR, ORR, and DOR. Results: All pts (n = 22) received nab-P/C; results for nivo-treated pts (n = 20) are presented. Of the nivo-treated pts, the median age was 66 y (55% ≥ 65 y), 75% were female, 80% were white, and 70% had ECOG PS 1. More pts had adenocarcinoma (50%) than squamous cell carcinoma (35%; 10% other, 5% data pending). No DLTs reported (5 DLT-evaluable pts). Most common grade 3/4 TEAEs were neutropenia (45%) and anemia (35%). No grade 3/4 immune-related colitis or pneumonitis reported. Best ORR (RECIST v1.1) was 50% (1 CR [unconfirmed, 5%] and 9 PRs [45%]; 6 pts had SD [30%]; 4 pts had PD [20%]). Best ORR by histology: squamous, 71%; nonsquamous, 54%. Median PFS was 10.5 months (squamous, 10.5 months; nonsquamous, not evaluable). Conclusions: Results demonstrated safety of the nivo + nab-P/C combination in NSCLC with no unexpected safety signals. Preliminary efficacy results are promising. (NCT02309177) Clinical trial information: NCT02309177.

Anti Tumor Activity

11565 Background: TAPUR is a phase II basket study evaluating anti-tumor activity of commercially available targeted agents in pts with advanced cancers with genomic alterations. Results in a cohort of STS pts with CDK4 amplification treated with P are reported. Methods: Eligible pts had advanced STS, no standard treatment options, measurable disease, ECOG PS 0-2, and adequate organ function. Genomic testing was performed in CLIA-certified, CAP-accredited site selected labs. Pts received P at 125 mg orally once daily for 21 days, followed by 7 days off until disease progression. Pts matched to P had CDK4 amplification and no RB mutations. Simon 2-stage design tested the null disease control (DC) - defined as partial (PR), complete response (CR) or stable disease at 16+ weeks (SD 16+) - rate of 15% vs. 35% (power = 0.85; α = 0.10). If ≥2 of 10 pts in stage 1 have DC, 18 more pts are enrolled. If ≥7 of 28 pts have DC, the null DC rate is rejected. Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety. Results: 29 pts (66% male) with STS with CDK4 amplification were enrolled from July 2016 to Nov 2019. 1 pt was not evaluable and excluded from efficacy analyses. Demographics and outcomes are summarized in Table. One pt with partial response (PR) and 12 pts with SD16+ were observed for DC and objective response (OR) rates of 48% (95% CI: 31%, 62%) and 3.7% (95% CI: 0.1%, 19%), respectively, and the null DC rate of 15% was rejected (p<0.001). 9/13 pts with DC continued on treatment for >32 weeks. 14 pts had at least one grade 3-4 AE at least possibly related to P with the most common being low WBC/platelets. Other grade 3 AEs included increased alanine aminotransferase, anemia, and fatigue. Conclusions: Monotherapy P demonstrated anti-tumor activity in heavily pre-treated pts with STS with CDK4 amplification. Additional study is warranted to confirm the efficacy of P in pts with STS with CDK4 amplification. Clinical trial information: NCT02693535. [Table: see text]

The aim of the study was to evaluate the use of specific collagen peptides in reducing pain in athletes with functional knee problems during sport. Athletic subjects (n = 139) with functional knee pain ingested 5 g of bioactive collagen peptides (BCP) or a placebo per day for 12 weeks. The primary outcome of the study was a change in pain intensity during activity, which was evaluated by the participants and the attending physicians using a visual analogue scale (VAS). As secondary endpoints, pain intensity under resting conditions, the range of motion of the knee joint, and the use of additional therapeutic options were assessed. The results revealed a statistically significant improvement in activity-related pain intensity in the verum group compared with placebo. (ΔVASBCP = 19.5 ± 2.4; ΔVASPlacebo = 13.9 ± 2.1; p = 0.046). The results were confirmed by the physician’s assessment. (ΔVASBCP = 16.7 ± 1.8; ΔVASPlacebo = 12.2 ± 1.8; p = 0.021). Pain under resting conditions was also improved, but no significance compared with placebo was detected (ΔVASBCP = 10.2 ± 18.4; ΔVASPlacebo = 7.4 ± 15.2; p = 0.209). Due to the high joint mobility at baseline, no significant changes of this parameter could be detected. The use of additional treatment options was significantly reduced after BCP intake. The study demonstrated that the supplementation of specific collagen peptides in young adults with functional knee problems led to a statistically significant improvement of activity-related joint pain.

LBA4003 Background: CRT is one of the best treatment options for localized EC. As new combinations are required to improve safety and survival, we launched a randomized phase II study to assess the complete response (CR) rate of CRT with FOLFOX versus 5FU/cisplatin in 97 pts with localized EC (Conroy 2010). The trial having met its objectives, it has been pursued as a phase III trial. Stratified randomization was performed centrally in a 1:1 ratio according to histological type, pretreatment weight loss in the prior 6 months (<10% vs ≥10%), ECOG PS (0 vs 1 vs 2), and center. Methods: Pts with technically unresectable cancer or those with surgical contraindications or who refused to undergo surgery were eligible. Eligibility criteria also included age >18 years (y), PS ≤ 2, previously untreated adenocarcinoma or squamous cell EC (any T, N0 or N1, M0 or M1a). The radiation dose was 50 Gy (2Gy/fr) 5 d/wk for 5 wks in both arms. In Arm A, pts received 6 bimonthly cycles (cy): oxaliplatin 85 mg/m2 d1 and leucovorin 200 mg/m2 followed by 5-FU 400 mg/m2 bolus d1 then 1,600 mg/m2 46h continuous infusion (ci) ; the first 3 cy were delivered during RT, the 3 other after. In Arm B, pts received 4 cy: cisplatin 75 mg/m2 d1 followed by 5FU 1,000 mg/m2/d ci d1-4, the first 2 cy during RT and 2 other after. The primary endpoint was PFS. Main secondary endpoints were OS, grade 3-4 toxicities, and quality of life. A total of 266 pts would provide 90% power to detect a 20% 3y-PFS difference (α=0.05). Results: 267 pts were enrolled between 10/2004 and 08/2011. Treatment cohorts were well balanced: male 81%; median age 61 y; PS 0 53%, squamous cell 85.8%, stage III 52%, IVA 6.0% and IVB 3.0%. Full treatment was delivered to 67.9% and 72.2% of pts in arms A/B, respectively. 7 toxic deaths occurred in each arm. Grade 3/4 toxicities per pt (%) in arms A/B were neutropenia 30.6/31.3, febrile neutropenia 5.3/7.0, anemia 5.4/11.0, asthenia 17.6/10.2, respectively. The median FU time was 25.3 mos. 3y-PFS was 18.2/17.4 % (HR=1.07; 95%CI =0.80-1.43) and median OS was 20.2 /17.5 m (HR=1.06; 95%CI =0.77-1.46). Conclusions: CRT with FOLFOX does not improve PFS compared to cisplatin and 5-FU and has similar toxicities.

624 Background: Indisetron is a 5-HT3 receptor antagonist that also antagonizes 5-HT4receptors. Indisetron tablets showed the non-inferiority to ondansetron tablets in terms of efficacy for preventing CINV. Moreover, preclinical data administered with irinotecan showed indisetron significantly reduced stool frequency in mice and inhibited the colonic peristalsis in dogs. We designed a pilot study compared with granisetron in the efficacy and tolerability of indisetron for irinotecan-induced nausea, vomiting and especially in diarrhea. Methods: Advanced colorectal cancer patients treated with FOLFIRI or IRIS (Irinotecan + S-1) with or without bevacizumab were enrolled in this study. Treatment: Arm A: indisetron tablets 8mg po day1. Arm B: granisetron 3mg iv day 1. The primary endpoints were the incidence of acute-onset diarrhea and complete protection from vomiting. Secondary endpoints were tolerability, complete protection from nausea and rate of no rescue medication. Results: Between May 2008 and July 2012, 33 patients (pts) were randomized. The study was closed prematurely due to poor accrual. Arm A: 16 pts, arm B 17 pts. Median age A: 68 y.o., B: 66 y.o.: ECOG PS 0/1: A: 12/4, B: 14/3pts. There was no significant difference of the incidence of acute-onset diarrhea between both groups (18.8% in A vs. 35.3% in B, p = 0.438). The proportion of complete protection from vomiting was 87.5% in A and 88.2% in B (p = 1.000). Similarly, complete protection from nausea, rate of no rescue medication, proportion of patients with a complete response (defined as no emetic episodes and no rescue medication) did not have a significant difference. Severity of nausea/vomiting and AE induced by 5-HT3 receptor antagonist were also similar between two groups. Conclusions: Compared with granisetron, indisetron showed effective and feasible results for preventing CINV induced by FOLFIRI or IRIS. Indisetron had also not improved the incidence of acute-onset diarrhea induced by irinotecan. Clinical trial information: UMIN000010162.

5501 Background: Deficient DNA mismatch repair (dMMR) occurs in approximately 15% of AEC and is associated with a high tumour mutation burden. Expression of PD-1 and PD-L1 has been reported in up to 90% of ECs, including those with proficient DNA mismatch repair (pMMR). We report here preliminary results of PHAEDRA, a single-arm phase 2 trial designed to determine the activity of single-agent durvalumab, an antibody to PD-L1, in 2 cohorts of women with AEC. Methods: Participants (pts) had pMMR AEC progressing after 1-3 lines of chemotherapy, or dMMR AEC progressing after 0-3 lines of chemotherapy, and were treated with durvalumab 1500mg IV Q4W. The primary endpoint was objective tumour response (OTR = complete response [CR] or partial response [PR] by iRECIST). Secondary endpoints included disease control at 16 weeks (DC16w = CR, PR, or stable disease at 16 weeks [SD16w]), immune-related adverse events (irAEs), PD-L1, germline mutations and MLH1 methylation. Other secondary endpoints include: OTR and DC by RECIST1.1, other AE, PFS, OS & quality of life will be reported later. Results: 71 pts with AEC were recruited from Feb 2017 to Sep 2018: 35 dMMR and 36 pMMR. Median follow-up were 8.3 vs 14.8 months in dMMR vs pMMR pts. Median age: 67 (range 36-81); ECOG PS: 0-1 in 68, and 2 in 3. Pathology: endometrioid in 94% and 58%; serous in 0% and 31%; grade: high in 42% and 83% (dMMR and pMMR respectively). Durvalumab was the 1st, 2nd and subsequent line of non-hormonal therapy in 15, 14, and 6 pts with dMMR and 0, 21, and 15 pts with pMMR. Among dMMR pts, the OTR rate was 40% (14/35, 95% CI 26-56), with 4 CR and 10 PR; 7 others had SD 16w for a DC16w rate of 60% (21/35, 95% CI 44-74). OTR rate was 40% as 1st line, 43% as 2nd line, and 33% as subsequent line treatment. Among pMMR pts, the OTR rate was 1/36 (3%, 95% CI 1-14) with 1 PR; 6 others had SD16w for a DC16w rate of 19% (7/36; 95% CI 10-35). IrAEs occurred in 14 pts: hyperthyroidism in 6, hypothyroidism in 6, pneumonitis in 1 and hepatitis in 1. Conclusions: Durvalumab monotherapy showed promising activity and safety in AEC with dMMR regardless of prior lines of chemotherapy, but there was limited evidence of activity in AEC with pMMR.

605 Background: MLN8237 is an investigational oral AAK inhibitor being evaluated in pts with hematologic (Ph III) and non-hematologic malignancies. We report here Ph II results from a, 5-arm study of single agent MLN8237 in pts with advanced, predominantly refractory, solid tumors (NCT01045421; closed for enrolment). Methods: Pts ≥18 years with relapsed/refractory disease measurable by RECIST, ECOG PS 0–1, and ≤2 prior (≤4 for BrC pts) cytotoxic chemotherapy regimens were enrolled. Pts with stable brain metastases were eligible. Pts were treated at the recommended Ph II dose; 50 mg BID for 7 d in 21-d cycles. For each cohort, a Simon’s 2-stage design was employed for Ph II, with ≥2 responses required in the first 20 response-evaluable pts to proceed to stage 2. The primary endpoint was overall response rate (ORR) by RECIST v1.1; safety and progression-free survival (PFS) were key secondary endpoints. Results: As of Dec 2012, 47 SCLC, 23 NSCLC, 49 BrC, 45 HNSCC and 47 GE pts in Ph II were response-evaluable (median age, 61 yrs [range 30–88]). NSCLC did not proceed to stage 2. ORR was 9%, 6%, and 4% in HNSCC, GE, and NSCLC pts, respectively; median PFS was 2.7, 1.5 and 3.1 months. BrC and SCLC data are shown in the Table. 92% of pts had a drug-related adverse event (DRAE). 57% of pts had Gr ≥3 DRAEs; including neutropenia (38%), anemia (10%), stomatitis (8%), and thrombocytopenia (6%). 22 pts died during the study; none were study-drug related. Conclusions: Single-agent activity of MLN8237 was evaluated across a range of solid tumors with a manageable toxicity profile. Encouraging Ph2 data in BrC and SCLC pts suggest that MLN8237 warrants further evaluation in these tumor types. Clinical trial information: NCT01045421. [Table: see text]

450 Background: Reolysin (reovirus serotype 3) contains a naturally occurring, ubiquitous, non-enveloped human dearing strain reovirus. Reovirus replicates in KRAS-mutant cells resulting in cell lysis. In phase I evaluation, CRC pts received single agent Reolysin with tumor stabilization and CEA response without significant toxicity. Reolysin and irinotecan (IRI) are synergistic in KRAS-mutant preclinical CRC models, providing rationale for this phase I study. Methods: This was a phase I dose escalation study of FOLFIRI + Reolysin. Eligible pts were >18 yrs with histologically confirmed KRAS-mutant mCRC, measurable disease, ECOG PS 0-1, <3 metastatic regimens, and adequate organ function. Standard FOLFIRI was administered with escalating Reolysin doses (range 1x1010 TCID50 to 3x1010 TCID50) in cohorts of 3-6 pts. Reolysin was given IV over 1 hr days 1-5 every 28d (1 cycle). Primary objectives were dose-limiting toxicity (DLT) to determine MTD and pharmacokinetics. Secondary endpoints were antitumor activity, response rate, progression-free and overall survival (PFS and OS). Results: 21 pts enrolled; median age 62 (range 39-77); 5 M; 16 F; FOLFIRI-naïve: 9/21 pts. 2 pts had DLTs in cycle 1 at the highest dose of 180 mg/m2 of IRI. Common (>10%) grade 3-4 toxicity include: neutropenia (n=11), anemia (n=4), and thrombocytopenia (n=3). One patient died of acute renal failure. The DLT is neutropenia. The recommended phase II dose is IRI 150 mg/m2 and Reolysin at 3x1010 TCID50 on days 1-5, q 28 days. 18 pts evaluable for response: PR (1pt; 5%), SD (9 pts; 50%), PD (8pts; 44%). 3 pts taken off study before evaluation. Median PFS: FOLFIRI-naïve pts = 7.4 mo. (95% CI = 1.9 mo., 12.9 mo.); Median PFS FOLFIRI non-naïve pts was not reached; overall median PFS = 7.4 mo. (95% CI = 0.6 mo., 14.1 mo.) Conclusions: The combination of Reolysin and FOLFIRI in pts with KRAS-mutant mCRC was safe, well tolerated and resulted in disease control in the majority of pts, including pts who previously progressed on IRI. We are encouraged by this activity and safety profile, and are planning additional studies. Clinical trial information: NCT01274624.

1008 Background: In KEYNOTE-012, pembro showed durable activity and manageable safety in patients (pts) with PD-L1+ mTNBC. Cohort A of KEYNOTE-086 (NCT02447003) examined the efficacy/safety of pembro in previously treated mTNBC, regardless of PD-L1 expression. Methods: Pts with centrally confirmed mTNBC, ≥1 prior chemotherapy for metastatic disease, and ECOG PS 0-1 had pembro 200 mg Q3W for up to 24 mo; imaging q 9 wk for the first 12 mo, then q 12 wk. Clinically stable pts with PD could remain on pembro until PD confirmed on next assessment. Primary endpoints: ORR (RECIST v1.1, central review) in all pts and pts with PD-L1+ tumors, and safety. Secondary endpoints: DOR, disease control rate (DCR; CR + PR + SD ≥24 wk), PFS, and OS. Planned enrollment was 160 pts; analysis based on data as of Nov 10, 2016. Results: 60% of screened PD-L1-evaluable pts had PD-L1+ tumors (combined positive score ≥1%). Of 170 pts enrolled (100% women; median age 54 y), 44% had ≥3 prior lines of therapy, 51% had elevated LDH, 74% had visceral mets and 62% had PD-L1+ tumors. After a median follow-up of 10.9 mo, 9 (5%) pts remained on pembro. Treatment-related AEs (TRAEs) of any grade and grade 3-4 occurred in 60% and 12% of pts, respectively; 4% discontinued due to TRAEs. There were no deaths due to AE. Overall ORR was 5% regardless of PD-L1 expression (Table). Best overall response was 0.6% CR, 4% PR, 21% SD; not evaluable (3%). DCR was 8% (95% CI 4-13). Median DOR was 6.3 mo (range 1.2+ to 10.3+); 5 (63%) responders w/o PD at data cutoff. Median PFS and OS were 2.0 mo (95% CI 1.9-2.0) and 8.9 mo (95% CI 7.2-11.2), with 6-mo rates of 12% and 69%, respectively. ORR was numerically lower in pts with poor prognostic factors (e.g., high LDH, liver/visceral mets; Table). Conclusions: In KEYNOTE-086 Cohort A, pembro monotherapy showed manageable safety and durable responses in a subset of pts with heavily pretreated mTNBC. Randomized studies of monotherapy and combination therapy are ongoing. Clinical trial information: NCT02447003. [Table: see text]

4563 Background: Previous reports have shown that the baseline neutrophil-to-lymphocyte ratio (NLR) is associated with prognosis in patients with mRCC. However, NLR has not been shown to reliably predict for response to IO. Retrospective analyses in metastatic melanoma and mRCC have shown an association of eosinophilia with improved outcomes to single agent immunotherapy. We sought to evaluate and compare the baseline NLR and NER with response to ipi/nivo in patients with mRCC. Methods: A retrospective review of patients with mRCC treated at the Vanderbilt-Ingram Cancer Center or Duke Cancer Institute with ipi/nivo was performed. Patients with clear cell histology and a baseline complete blood count with differential were included. Patients previously treated with IO were excluded. Patients were separated into groups (above and below the median) based on baseline median NER and baseline median NLR. Analyses of progression free survival (PFS) and overall survival (OS) were conducted using the log rank test. The odds ratio (OR) for objective response rate (ORR) was analyzed using Fisher’s exact test. Results: 111 patients met inclusion criteria. The median age was 60, 77% of patients were male, 68% had prior nephrectomy, 74% were naïve to systemic therapy, and 84% were IMDC intermediate/poor risk. The median NER was 25.0 and median NLR was 3.4. Patients with < median baseline NER had significant improvement in PFS, OS, and ORR (see table). Patients with < median baseline NLR had significant improvement in OS but not in PFS or ORR. Conclusions: Baseline NER was associated with improved outcomes with ipi/nivo. While both NER and NLR were associated with improved OS, only NER was additionally associated with both improved PFS and ORR. With multiple first-line treatment options for mRCC, baseline NER may serve as an early non-invasive predictor for response to ipi/nivo.[Table: see text]
