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.

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.

Abstract Genomic aberrations in the cell cycle and PI3K pathway are commonly observed in recurrent childhood brain tumors. Dual inhibition of CDK4/6 (ribociclib) and mTOR (everolimus) has strong biologic rationale, non-overlapping single-agent toxicities, and adult clinical experience. The maximum tolerated dosage (MTD) and/or recommended phase two dose (RP2D) of ribociclib and everolimus was determined in the Phase I study and ribociclib concentrations were characterized in plasma and tumor in children undergoing neurosurgical procedures. Following resection, eligible patients were enrolled in the Phase I study according to a rolling 6 design and received ribociclib and everolimus once daily for 21 days and 28 days, respectively. Patients undergoing surgery received ribociclib at the pediatric RP2D (350 mg/m2/day) for 7–10 days pre-operatively. Pharmacokinetic samples were collected on both cohorts and analyzed in nine patients on phase I study. Sixteen eligible patients enrolled on phase I study (median age 10.3 years; range: 3.9–20.4) and 5 patients were enrolled on the surgical cohort (median age 11.4 years; range: 7.2–17.1). Six patients enrolled at dose level 1 without dose limiting toxicities (DLT). Two of the three patients at dose level 2 experienced DLT (grade 3 hypertension and grade 4 ALT). The most common grade 3/4 toxicities were lymphopenia, neutropenia, and leucopenia. Everolimus concentrations following administration of everolimus alone were lower than those following drug combination, suggesting an impact of ribociclib on everolimus pharmacokinetics. The MTD/RP2D of ribociclib and everolimus in recurrent CNS tumors is 120 mg/m2 and 1.2 mg/ m2 daily for 21 days and 28 days, respectively.

12012 Background: The combination of D and T has many potential applications, particularly in breast and ovarian cancers. A phase 3 trial is examining D + T versus T in first-line metastatic breast cancer ( NCT00091442 ). D has better tumor localization and penetration in solid tumors than conventional doxorubicin. In previous studies, the maximum tolerated dose (MTD) of the combination was identified as D 30 mg/m2 and T 75 mg/m2 q4 weeks (wks), with a recommended dose and schedule of D 30 mg/m2 and T 60 mg/m2 q3wks without G-CSF. We conducted a phase I study to determine the MTD of D with weekly T. Our hypothesis was that the lower incidence of myelosuppression with weekly T would allow for higher doses of both drugs. Methods: There were 2 schedules. Arm A: D q4wks starting at 25 mg/m2 with weekly T for 3 wks starting at 30 mg/m2. Arm B: D q2wks starting at 15 mg/m2 with weekly T for 3 wks starting at 30 mg/m2. One cycle was 28 days. Standard 3+3 design was used with MTD defined as the highest dose level causing dose limiting toxicity (DLT) in ≥ 2/6 patients (pts). Results: 32 pts were treated; 13 females, 19 males, median age of 60 years. Median number of cycles administered was 2 (1–13) with a median follow-up of 11.5 months. Tumor types included lung (16%), thyroid (9%), esophagus (9%), nasopharynx, breast, colorectal, stomach and kidney (6% each). Arm A (13 pts) was closed after 2/7 evaluable pts at dose level 2 (D 33mg/m2; T 30 mg/m2) experienced DLT in the form of grade 3 stomatitis. The most common grade 3/4 toxicities were neutropenia (3/13), stomatitis (3/13) and fatigue (3/13). Arm B accrued 19 pts. The trial was closed at the highest planned dose in Arm B (D 20mg/m2 q2wks and T 35 mg/m2 weekly) with only 1/6 evaluable pts experiencing DLT in the form of grade 4 fatigue and weakness. The most common grade 3/4 toxicities in Arm B included neutropenia (5/19 pts), fatigue (5/19 pts) and stomatitis (2/19 pts). There was no grade 3/4 hand-foot syndrome or cardiotoxicity. 2 partial responses were observed in nasopharyngeal and salivary gland carcinomas, with 13 pts achieving stable disease. Conclusions: The combination of D q2 wks and T weekly for 3/4 wks is well tolerated and results in a higher dose intensity of both drugs than in previously evaluated regimens. [Table: see text]

1066 Background: Inhibition of mTOR with everolimus (E) may improve efficacy in combination with docetaxel (D), but both drugs are metabolized by CYP3A4, thus a pharmacokinetic (PK) interaction may also exist. Methods: 15 patients (pts) with MBC were treated with docetaxel and everolimus using the continuous reassessment method (CRM) to determine maximum tolerated dose (MTD). Docetaxel doses were 40–75 mg/m2 IV on day 1 of a 21 day cycle. Everolimus doses were 20–50 mg PO on days 1 and 8 of a 21 day cycle (except cycle 2, where only day 8 was given to allow single agent PK analyses of both drugs). Response was measured every 2 cycles using RECIST. Results: Median age= 58 years and 77% of pts had >2 prior chemotherapies for MBC. Initially 2 of 2 pts treated (D= 75 mg/m2, E= 30 mg) developed DLT (neutropenic fever/infection), prompting a mandatory PK evaluation for all pts enrolled in subsequent cohorts. A second cohort of 3 patients (D=60 mg/m2, E=20mg) had no DLT, but no pts received day 8 of E due to grade 3–4 neutropenia. PK analyses demonstrated a 42% lowered (-42%) D clearance at the 60 mg/m2 in the presence of E (n=1). Subsequent cohorts were accrued at D=40 mg/m2 with escalating doses of E (Table). For the entire group, an 18% decrease (-18%) in D clearance was observed when D was administered concomitantly with E. High interpatient variability of D clearance was observed (range +16% to -135%). No pts had CR/PR, but 6 had SD>4 cycles and 2 had SD=8 cycles. Conclusions: Weekly everolimus appears to cause widely variable and unpredictable changes in docetaxel clearance making this combination unfeasible.

7093 Background: Increased serum levels of insulin like growth factor (IGF), plus overexpression of the IGF-receptor (IGFR) are implicated in SCLC cell growth and proliferation, making suppression of the IGFR a potential therapeutic target. MK-0646 is a monoclonal antibody directed against the IGFR. The aim of this study was to determine the recommended phase II dose (RP2D) of cisplatin, etoposide plus MK-0646. Methods: We conducted a phase I study of two dose levels of MK-0646 (DL1 5mg/kg, DL2 10mg/kg IV weekly) in combination with cisplatin (25mg/m2) and etoposide (100mg/m2) IV D1-3, q21d, for patients with chemotherapy-naive ES SCLC, PS 0-2. Patients with treated stable brain metastases were eligible. Patients completing 4-6 cycles of combination therapy could continue single agent MK-0646 until disease progression. Primary outcome was determination of the RP2D. Secondary outcomes included ORR (RECIST 1.1), and toxicity (CTCAEv3). Results: A total of 12 patients were treated (DL1 – 3, DL2 – 9). The median age was 63 years (48-70), with 6 males and 6 females. Most subjects were good ECOG PS (PS 1 – 8, PS 2 – 4) and had 4 or more sites of disease (n=8). No DLTs were observed in DL1 or DL2. In an expanded DL2 cohort, 1 patient died from neutropenic sepsis during cycle 1. The median number of treatment cycles of chemotherapy was 4 (DL1) or 5 (DL2) and MK-0646 was 6 (DL1&2). Dose delays were observed for chemotherapy (DL1 - 2, DL2 – 6) and MK-0646 (DL1 – 3, DL2 – 7). The confirmed ORR was 72.7% (PR 8, SD 2, PD 1, non-evaluable 1). Grade ≥3 toxicities (any cycle) occurring in more than 1 patient included: neutropenia (92%); thrombocytopenia (25%); leukopenia (50%); anemia (17%); fatigue (33%); joint pain (17%); thrombosis (25%). Grade 2 or 3 hyperglycemia was observed in 1 of 3 (DL1) and 5 of 9 (DL2). Eight SAEs were observed in 3 patients (thrombosis, febrile neutropenia, infection, syncope, fatigue 2, dyspnea, back pain). Conclusions: MK-0646 can be combined at full dose with standard doses of cisplatin and etoposide (25mg/m2 and 100mg/m2 D1-3) with a RP2D of MK-0646 10mg/kg/week. The observed toxicities are consistent with that expected from cisplatin and etoposide except for hyperglycemia, which appears dose dependent.

8556 Background: The PI3k/AKT pathway is activated in most metastatic melanomas; mTOR is a critical component of this pathway. Everolimus, an mTOR inhibitor, has demonstrated single-agent activity in patients with advanced melanoma. We evaluated the efficacy and toxicity of everolimus in combination with paclitaxel/carboplatin in patients with advanced melanoma. Methods: Eligible patients had stage IV or unresectable stage III melanoma, unselected for braf status, previously untreated with chemotherapy or targeted agents. Previous immunotherapy was allowed. Additional eligibility criteria: ECOG PS 0 or 1; measurable disease; no active brain metastases; adequate bone marrow, kidney, and liver function; informed consent. All patients received paclitaxel 175mg/m2, 1-3 hour IV infusion, and carboplatin AUC 6.0 IV on day 1 of each 21-day cycle. Everolimus 5mg PO was given daily. Patients were evaluated for response every 6 weeks; treatment continued until progression or undue toxicity. Median progression-free survival (PFS) for paclitaxel/carboplatin treatment is 4 months; we looked for a median PFS of 6 months with this novel combination. Results: Seventy patients were treated between 2/2010 and 2/2011; median age 63, 90% had stage IV melanoma. 91% of patients received at least 2 cycles of therapy; median cycles received: 4 (range: 1-25+). Twelve patients (17%) had partial responses; an additional 42 patients (60%) had stable disease at first reevaluation. After a median 13 months of followup, the median PFS for the entire group was 4 months (95% CI: 2.8 – 5.0 months); 96% had progressed during the first 12 months. Median survival was 10 months (95% CI: 7.3 – 10.9 months). Toxicity was as previously described with these agents; neutropenia was the most common grade 3/4 toxicity (27%). Only 3 patients stopped treatment due to toxicity. Conclusions: The addition of everolimus to paclitaxel/carboplatin was feasible and well-tolerated; however, efficacy results were similar to those reported with paclitaxel/carboplatin alone. Further development of this combination regimen for treatment of metastatic melanoma is not recommended.

2602 Background: ASP3026 (3026) is a selective, potent, ATP-competitive, small molecule oral inhibitor of ALK receptor tyrosine kinase that has not previously been tested in humans. A Phase 1 dose-escalation trial, using a 3+3 design, evaluating 3026 as an oral single agent was conducted to investigate PK (Day 1 and Day 28), safety and clinical activity in patients (pts) with advanced malignancies (excluding leukemias) of ECOG PS 2 or less. Methods: 3026 was administered under fasting conditions on a continuous schedule to pts in successive dose-escalating cohorts at doses ranging from 25 mg QD to 800 mg QD. Results: Thirty pts were enrolled into the dose escalation part of the study. The MTD was determined based on DLT data from cycle 1. Three DLTs were observed: grade 2 nausea and vomiting leading to dose reduction at 525 mg QD; grade 3 rash leading to dose reduction, and grade 3 ALT/AST increase leading to study withdrawal at 800 mg QD. The most common AEs were constipation, vomiting, diarrhea, nausea and abdominal pain, and all AEs were manageable and reversible. Median AUC and Cmax increased proportionally with dose from 25 mg QD to 800 mg QD. There was no evidence of non-linear PK at ASP3026 doses >25 mg QD. The median terminal half-life was approximately 10 - 41 hours. Overall, A3026 appears well absorbed with median Tmax around 3 hours for both Day 1 and Day 28. Terminal T1/2 appears adequate for one daily dosing with median values ranging from approximately 18 to 34 hours. Based on visual inspection of pre-dose (trough) values from Days 8, 15, 22, and 28 it appears that steady-state conditions are achieved by day 28. Conclusions: The MTD of 3026 is 525 mg QD. Treatment with 3026 resulted in a promising safety and PK profile in pts with advanced malignancies. Further evaluation of 3026 in pts with tumors harboring gene mutation or ALK fusion genes in the cohort expansion phase at the MTD is ongoing. Clinical trial information: NCT01401504.

571 Background: Both SOX and cet are effective treatments each other in patients (pts) with mCRC. COIN trial indicated that the use of cet in combination with capacitabine and oxaliplatin should not be recommended. However, the safety and efficacy of cet plus SOX are not clear. To evaluate the safety and clinical efficacy of the combination, we conducted a multi-center phase I/II study. Methods: In this trial, we assigned pts with KRAS wild type (wt), EGFR-expressing tumor and no prior chemotherapy to receive cet (initial dose 400, and 250 mg/m2 weekly) followed by SOX (oxaliplatin on day 1 and S-1 40 mg/m2 twice daily on days 1-14). The treatment was repeated every 3 weeks. The phase I part was designed to determine the maximum tolerated dose (MTD) and recommended dose (RD) according to the dose adaptation schedule of oxaliplatin (100 mg/m2 for level 1 and 130 mg/m2 for level 2). In the following phase II part, the enrolled pts were treated with the RD. The primary endpoint was response rate (RR) evaluated by the external review board according to RECIST criteria v1.1. Secondary endpoints included PFS, OS, and safety. In addition, we prospectively evaluated early tumor shrinkage (ETS). Results: A total of 67 pts were enrolled from January 2012 to February 2013. In the phase I part, level 2 was determined to be the RD. The MTD was not determined because dose limiting toxicity was not confirmed in level 2. In the phase II part, 59 pts including 6 pts of phase I cohort were assessable for the efficacy. The median age was 64 years, 51% of pts were male, and ECOG PS 0 was observed in 85% of pts. The median course of treatment was 5 (range 1-14). The RR was 62.7% (95%CI, 50.4 to 75.1) and ETS was observed in 72% of pts. In safety analysis, grade 3 or worse adverse events were platelet count decreased (13.1%), neutropenia (8.2%), anorexia (11.7%), rash acneform (6.7%) and peripheral neuropathy (3.3%). Conclusions: We determined the RD of cet plus SOX treatment in pts with mCRC. This combination is tolerable at full doses of cet and SOX, with manageable toxicities, and demonstrates advantages in RR for pts with KRAS wt tumor. Updated safety and efficacy data will be presented. Clinical trial information: UMIN000007022.

11054 Background: Advanced SyS are rare tumors with limited curative options. FZD10 is highly expressed in SyS but not in normal adult tissue. OTSA101 is a MAb targeting FZD10, labelled with a radioisotope. Methods: We conducted a phase I, FIH study including adult pts with advanced, refractory SyS. In part 1, pts received OTSA101 labelled with In111 used as radiotracer to assess biodistribution and tumor uptake. In part 2, pts with significant tumor uptake were randomized to receive OTSA101 labelled with 370MBq of Y90 (Arm A) or 1110MBq Y90 (Arm B). Primary endpoints were occurrence of unacceptable biodistribution /lack of tumor uptake in part 1 and occurrence of related adverse events (AEs) Grade ≥ 3 during the first 8 weeks following injection of Y90OTSA101 in part 2. Responses were assessed per RECIST 1.1. Results: From January 2012 to June 2015, 20 pts (10 females, median age 43, range 21-67) with advanced SyS were enrolled. Ten pts (50%) had sufficient tumor uptake to proceed to part 2 and 8 were randomized (Arm A: 3 and Arm B: 5). Two pts were not randomized due to worsening PS. During part 2, the most common Grade ≥ 3 AEs were haematological, including reversible lymphopenia, thrombocytopenia and neutropenia, and were more common in Arm B. One pt with SD after 12 weeks received a 2nd injection of 90Y-OTSA101, but experienced fatal hemoptysis. No objective response was observed. Best response was SD in 5/8 pts lasting up to 21 weeks for 1 pt. Conclusions: This FIH shows that radioimmunotherapy targeting FZD10 is feasible and safe in SyS pts. Tumor uptake was heterogeneous but sufficient to select 50% of pts for 90Y-OTSA101 treatment. Due to limited sample size, further clinical investigations are needed to assess the therapeutic activity of 90Y-OTSA101 with a recommended dose of 1110MBq of 90Y. Clinical trial information: NCT01469975.

365 Background: We aimed to compare the efficacy and tolerability of SECOX regimen with sorafenib alone as first-line treatment of advanced hepatocellular cancer (HCC) in a multicenter, open-label and randomized setting. Methods: Patients not suitable for surgery or various loco-regional therapies and no prior systemic therapy for advanced HCC were recruited in 3 centres. Eligible patients were randomly assigned to receive either SECOX (sorafenib 400 mg BD continuously, oxaliplatin 85 mg/m2 on D1, and capecitabine 1700 mg/m2 on D1-7 q2w) or sorafenib alone continuously in 1:1 ratio. Primary endpoint was time-to-progression (TTP). Secondary endpoints were tolerability, overall tumor response rate, overall survival (OS) and progression-free survival (PFS). Results: Forty-six patients were randomized and treated, of whom 22 were in the SECOX arm. Median age was 64 years and majority of the patients were male (72%). 40 patients (87%) were hepatitis B carrier, and 42 patients (91%) had Child-Pugh A liver function. Thirty patients (65%) had received prior non-systemic treatment for HCC. Median duration of follow-up was 7.8 months (mos) (range 0.3-25.8). At the time of analysis,one patient in the SECOX arm is still receiving treatment. Median TTP was 3.2 mos (95% CI 1.7-5.8) for SECOX vs 2.8 mos (95% CI 1.8-4.0) for sorafenib. The hazard ratio (HR) for TTP was 0.91 (95% CI 0.5-1.7; p=0.77; predetermined futility boundary HR ≥ 0.86). Median OS was 7.1 mos (95% CI 3.0-15.3) for SECOX vs 12.5 mos (95% CI 7.2-15.4) for sorafenib (p=0.29). Median PFS was 3.1 mos (95% CI 1.6-5.8) for SECOX vs 2.7 mos (95% CI 1.8-4.0) for sorafenib. 2 patients (9%) and no patients achieved partial response in the SECOX and sorafenib arms, respectively. The clinical benefit rate (CR+PR+SD) was 36% for the SECOX arm and 21% for the sorafenib arm (p=0.50). Incidence of treatment-related adverse events (trAEs) was common in both SECOX and sorafenib arms (64% and 71% respectively, p=0.75). The most common grade 3-4 trAE was ALP increase (14%) for SECOX and hand-foot skin reaction (25%) for sorafenib. Conclusions: The addition of capecitabine and oxaliplatin to sorafenib did not result in significant improvement in TTP. Clinical trial information: NCT02716766.
