8570 Background: Plinabulin (BPI-2358) is a vascular disrupting agent with immune-enhancing function by inducing dendritic cell maturation and decreasing regulatory T cells. Preclinical studies report that plinabulin potentiates the cytotoxicity of dual checkpoint inhibition (CPI) with nivolumab and ipilimumab. Plinabulin may also reduce immune-related AEs from CPI through its phosphodiesterase-4 (PDE4) inhibitory activity which is associated with anti-inflammatory effects. We report initial results from a Phase I study assessing plinabulin in combination with nivolumab and ipilimumab. Methods: In this dose-escalation phase I study, patients with extensive-stage SCLC who had progressed on or after prior platinum-based chemotherapy (±CPI) were enrolled using a 3+3 design. The primary objective was to determine dose-limiting toxicities (DLT’s) and recommended Phase 2 dose (RP2D). Patients received nivolumab (1 mg/kg), ipilimumab (3 mg/kg) and plinabulin (as per dose escalation schema) IV on day 1 of each 21 day cycles. After completion of 4 cycles, patients continued therapy with nivolumab (240 mg) and plinabulin every 2 weeks till progression or intolerable toxicity. Patients were evaluable for DLT if they received at least 2 cycles of therapy; DLT period was defined as the first 6 weeks from C1D1. Secondary endpoints were ORR, PFS and frequency of irAEs. Correlative analysis included inflammatory biomarkers: hsCRP, ESR, SAA and haptoglobin. Results: Between 9/2018 and 11/2020, 17 patients were enrolled (1 patient withdrew consent before treatment, 16 were evaluable for safety). Median age was 59 years (range 43 to 78); 9 patients were male and 10 had received prior CPI. Eight patients were treated at dose-level 1 of plinabulin (20 mg/m2) and 8 patients at 30 mg/m2 of plinabulin (level 2); dose-level 2 was determined to be RP2D. There were 2 DLTs; 1 at dose-level 1 (grade 3 altered mental status lasting < 24 hours) and 1 at dose-level 2 (grade 3 infusion reaction). The most common treatment-related AEs (all grades) were nausea (10; 63%), infusion reaction (8; 50%), vomiting (7; 44%), diarrhea (7; 44%) and fatigue (6, 32%). Seven patients (44%) had at least one grade 3 or higher treatment-related AE; there were no treatment-related deaths. Two patients (13%) had grade 3 or higher irAE requiring steroids (1 colitis, 1 transaminitis); both at dose-level 1. At data cutoff (12/30/20), there were 3 PRs in CPI naïve patients (3/6; 50%) and 2 PRs in evaluable CPI-resistant patients (2/7; 29%). In the two CPI-resistant patients with confirmed response, the tumor reduction was 68% and 52%. Conclusions: Plinabulin in combination with nivolumab and ipilimumab was safe and well tolerated. A phase 2 study in CPI-experienced patients with relapsed SCLC is planned to confirm the preliminary signals of clinical activity and reduced immune toxicity. Clinical trial information: NCT03575793.

BackgroundLutathera is a 177Lutetium-labeled somatostatin analog approved for the treatment of gastroenteropancreatic neuroendocrine tumors (NETs). Somatostatin receptors are expressed in small cell lung cancer (SCLC). Nivolumab, an anti-PD-1 antibody, may act synergistically with lutathera to generate antitumor immunity. We conducted a phase I study of lutathera plus nivolumab in patients with advanced NETs of the lung.MethodsPatients with relapsed/refractory extensive-stage SCLC (ES-SCLC), non-progressing ES-SCLC after first-line platinum-based chemotherapy, or advanced grade I-II pulmonary NETs were eligible. The primary objective was to determine the recommended phase 2 dose (RP2D). The phase I portion followed a standard 3+3 design, assessing two dose levels (dose level 1: lutathera 3.7 GBq every 8 weeks for four doses with nivolumab 240 mg every 2 weeks; dose level 2: lutathera 7.4 GBq every 8 weeks for four doses with nivolumab 240 mg every 2 weeks).ResultsNine patients were enrolled (six ES-SCLC, two pulmonary atypical carcinoid, one high-grade pulmonary neuroendocrine carcinoma). No dose-limiting toxicities (DLTs) were observed at dose level 1. At dose level 2, one patient with refractory ES-SCLC developed a DLT (grade 3 rash). The most common treatment-related adverse events (TRAEs) were lymphopenia (n=7), thrombocytopenia (n=4), anemia (n=3), and nausea (n=3). The most common grade 3 TRAE was lymphopenia (n=4). Among the seven patients with measurable disease, one patient with ES-SCLC had a partial response. Two patients with pulmonary atypical carcinoid had stable disease lasting 6 months. The RP2D was dose level 2.ConclusionsLutathera plus nivolumab was well tolerated and showed signs of antitumor activity. This combination warrants further exploration.Trial registration numberNCT03325816

e13501 Background: Loss of estrogen receptor alpha gene expression has been associated with insensitivity to endocrine therapy in human breast cancer patients. Histone deacetylase (HDAC) inhibitors have recently been found to restore sensitivity to the estrogen receptor by modulation of the estrogen and progesterone receptors. This had been shown with both aromatase and tamoxifen refractory and in triple negative cell lines . We performed a Phase I study of the combination of LBH589 (panobinostat) and letrozole to evaluate safety and tolerability in patients with metastatic breast cancer prior to the performance of a phase II trial. Methods: We enrolled postmenopausal women with metastatic breast cancer, ECOG PS 0 or 1, ANC>1500/mm3, platelets>100,000/mm3, normal total bilirubin, and ALT/AST adequate laboratory tests were eligible. Letrozole dose was 2.5 mg/day orally. Dose of LBH589: Level 1, 20 mg orally three times weekly; Level 2, 30 mg orally three times a week. Results: 12 patients (dose level 1:6 patients, dose level 2: 6 patients) have been enrolled. 43 cycles of treatment have been given to these12 patients. Initial cohort of 3 patients at the 20 mg dose level had no dose limiting toxicity (DLT). At the 30 mg dose level 3/6 patients had DLT (thrombocytopenia grade 1: 2 pts; grade 3:1 pt; grade 4: 1 pt; and diarrhea grade 3: 1 pt. One pt at the 30 mg dose level has a confirmed partial response and remains on study after 6 cycles of treatment. Subsequent cohort of 3 patients had 1 dose DLT with doubling of the creatinine. The main DLT was thrombocytopenia in 3/6 pts at the 30 mg dose level. Conclusions: The recommended dose for phase II testing of LBH589 is 20 mg orally 3 times per week in combination with standard dose letrozole.

Abstract Background: CPX-351 is a liposomal formulation of Ara-C and DNR which fixes the synergistic 5:1 molar ratio found to enhance efficacy in both in vitro and in vivo preclinical leukemia models. CPX-351 overcomes the pharmacokinetic (PK) differences of each drug, enabling the maintenance of the 5:1 molar ratio for extended periods of time after IV administration and the delivery of this ratio to bone marrow. Preclinical data from in vitro models show that CPX-351 is actively internalized by leukemic cells within vacuoles and subsequently releases DNR intracellularly. A Phase I study was performed with CPX-351 in patients with acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL), and myelodysplastic syndrome (MDS). Objectives: to determine safety, tolerability, and pharmacokinetics of a 90 min IV infusion of CPX-351 given on days 1, 3, 5 to patients with advanced leukemia and MDS, and to seek preliminary evidence of antitumor activity. Methods: Patients with relapsed/refractory AML/ALL and MDS were eligible. A second induction course was permitted if the day 14 bone marrow showed evidence of antileukemic effect and persistent leukemia. Dosing started at 3 units/m2 (1 u = 1 mg Ara-C and 0.44 mg DNR) using single patient cohorts and dose doublings. Three patient cohorts and 33% dose increments began after evidence of antileukemic activity and continued until limiting toxicities (DLTs) completed dose escalation. PK samples were collected after each dose. Results: Forty-seven subjects received 69 courses of CPX-351: Male/Female = 31/16, median age = 62 years (range 23–81); 44 patients had AML and 3 patients had ALL; median number of prior regimens = 2 (1–7). Thirty-seven patients entered the escalation phase of the study and ten subjects, most in first relapse, were treated after completion of dose escalation to confirm safety. At 24 u/m2 antileukemic effects were observed leading to increased cohort size to 3 and decreased escalation rate to 33%. The MTD and recommended Phase 2 dose was 101 u (101 mg Ara-C + 44 mg DNR)/m2 after observing 3 DLTs (decreased LVEF, hypertensive crisis, prolonged aplasia) at 134 u/m2. Adverse events data are available for 36 of 37 patients from the escalation phase of the study. Nonhematologic grade 3–5 toxicities occurring in more than one patient included: infections (58%), dyspnea (11%), fever (11%), hypophosphatemia (8%), hypokalemia (6%), renal failure (6%), skin rash (6%), headache (6%) hyperglycemia (6%) hypoxia (6%) and respiratory failure (6%). Mucositis of any grade was observed in 42% of patients with 3% having grade 3 mucositis. Diarrhea of grade 1 and 2 severity occurred in 39% of patients. Interim analysis of PK data demonstrates maintenance of the 5:1 molar ratio and detectable encapsulated drug persisting up to 24 hours. The average half-lives were 35 hr for total Ara-C and 23 hr for DNR, significantly longer than reported for the conventional drugs. Overall, 11 patients achieved CR/CRp. Among the 19 patients treated at the MTD, 5 of the 13 patients evaluable for response achieved CR. Six patients were treated above the MTD (134 u/m2) and 2 achieved CR. Median time to CR was 43 days. Conclusions: The recommended phase 2 dose is 101 u/m2. CPX-351 was well tolerated, with no unexpected toxicities noted up to the MTD. GI toxicities and mucositis were transient and nearly always of mild to moderate severity. Reduced LV function was observed in two patients both with substantial prior anthracycline exposure. CRs were observed in heavily pre-treated patients with relapsed/refractory AML. Future plans include a randomized Phase 2 study comparing CPX-351 versus Cytarabine + Daunorubicin (“7 + 3”) in older (&gt;60 yo) subjects with previously untreated AML, and a phase 2 study in patients with AML in 1st relapse.

Abstract Abstract 3443 Poster Board III-331 Introduction The first Phase I-II clinical trial of oxaliplatin, fluradabine, cytarabine (Ara-C), and rituximab (OFAR1) demonstrated significant activity in refractory CLL and RS (Tsimberidou et al, J Clin Oncol, 2008;26:196). To enhance the response rate and decrease myelosuppression, the dose of oxaliplatin was increased to 30mg daily, the dose of Ara-C was decreased to 0.5g/m2 daily and the optimal number of days of fluradabine and Ara-C administration was explored (OFAR2). Methods In a Phase I-II study of OFAR2, patients were treated with oxaliplatin 30mg/m2, D1-4; fludarabine 30mg/m2, Ara-C 0.5g/m2; rituximab 375mg/m2, D3; and pelfigrastim 6mg, D6. Fludarabine and Ara-C were given on D2-3 (dose level 1) D2-4 (dose level 2) or D2-5 (dose level 3); courses were repeated every 4 weeks. Patients received prophylaxis for tumor lysis, DNA viruses, and PCP. A “3+3” design was used and the planned number of patients in the Phase II was 90 (CLL, 60; RS, 30). Results Ninety-one patients (CLL, 67; RS, 24) have been treated to date: Phase I, 12 patients (by dose level: 1, n=3; 2, n=6; and 3, n=3). DLTs were noted in 2 of 3 patients on dose level 3 (G4 diarrhea, 1; G4 neutropenic sepsis, 1); thus, dose level 2 was the MTD. Seventy-nine patients (relapsed CLL, 58; RS, 19) have been treated in the Phase II portion of the study. Patient characteristics were as follows: age > 60 years, 65%; 17p deletion, 38%; 11q deletion, 13%; 13q deletion, 16%; trisomy 12, 21%; no findings, 12%; unmutated IgVH, 80%; ZAP70-positive, 75%; and CD38 ≥30%, 58%. Response in patients treated in the Phase II recommended dose is shown in Table (evaluable, 67). The overall response rates in patients with 17p and 11q deletions were 48% and 55%, respectively. The median survival duration was 21 months (CLL, 21 months; RS, 9.5 months). At 18 months, the survival rates in patients with 17p and 11q deletions were 66% and 76%, respectively. Twelve patients underwent stem cell transplantation after OFAR2 (as post-remission therapy, n=10; as salvage, n=2). Overall, 196 cycles were administered. Grade 3-4 neutropenia, thrombocytopenia, and anemia were noted in 63%, 72%, and 39% of patients and in 57%, 70%, and 25% of cycles and Grade 3-4 infections in 19% of patients. Conclusion Preliminary results demonstrated that OFAR2 induced response in 40% of patients with RS and 63% of patients with relapsed/refractory CLL. OFAR2 had antileukemic activity in patients with 17p deletion. Clinical outcomes appeared to be superior to those of OFAR1 in refractory CLL, whereas results of OFAR1 appeared to be superior to those of OFAR2 in RS. Accrual is ongoing.

Abstract The maximum tolerated dose (MTD) of idarubicin has been acknowledged to be 12-15 mg/m2/day for 3 days for acute leukemias. Its MTD should be reevaluated in the treatment of acute myeloid leukemia (AML) in the era of granulocyte colony-stimulating factor and better supportive care. We conducted a phase I study to investigate the safety of escalating doses of idarubicin in combination with cytarabine 100 mg/m2/day for 7 days for previously untreated AML. The starting dose of idarubicin was 12 mg/m2/day for 3 days with dose escalations by 3 mg/m2/day. Cohorts of three patients were treated at each dose level, and the idarubicin dose was escalated up to 18 mg/m2/day until at least two patients among a cohort of three to six patients experienced the dose-limiting toxicities (DLTs) (traditional 3+3 design for phase I clinical trials: J Natl Cancer Inst 2009;101:708). Hematologic DLTs were defined as the time to recovery of neutrophils {absolute neutrophil count (ANC) ≥500/μL} or platelets (platelet count ≥20,000/μL) exceeded 42 days after the start of induction therapy (J Clin Oncol 2004;22:4290). Non-hematologic DLTs were defined as grade 4 or 5 toxicities (Leukemia 1998;12:865). We adopted the NCI CTCAE v3.0 to grade the hematologic and non-hematologic toxicities. Thirteen adult patients were enrolled in the study, but two and two were excluded at level 1 and level 2, respectively, because they received reinduction therapy for resistant disease within 4 weeks after the start of the assigned induction therapy. Consequently, nine patients were evaluable for the phase I study. The median times to recovery of neutrophils (ANC ≥500/μL) after the start of induction therapy at level 1, level 2, and level 3 were day 20 (range, 19-22), day 19 (range, 17-20), and day 25 (range, 21-26), respectively. The median times to recovery of platelet (platelet count ≥20,000/μL) at each level were day 20 (range, 19-23), day 20 (range, 16-34), and day 24 (range, 20-35), respectively. Therefore, grade 4 hematologic toxicities were observed at all 3 levels; however, these hematologic toxicities did not meet the criteria of the hematologic DLTs as defined in this study. There was any instance of grade 4 non-hematologic toxicity at each dose level. No death associated with the induction treatment was observed in this trial. Hematologic and non-hematologic DLTs as defined above were not observed at all 3 dose levels; therefore, idarubicin 18 mg/m2/day for 3 days could be defined as the MTD for this trial. Disclosures No relevant conflicts of interest to declare.

Abstract Background: Despite advances in chemotherapy, R/R HL remains a significant clinical problem with over 1,000 primarily young lives lost annually. HL is a unique tumor in which a small number of malignant Hodgkin Reed-Sternberg (HRS) cells propagate an immunosuppressive microenvironment that augments HRS growth and survival. We hypothesized that immune checkpoint inhibitor therapy could activate the tumor immune microenvironment, while the CD30 expressing HRS cells could be targeted by brentuximab vedotin (BV), thereby overcoming tumor cell resistance and deepening clinical responses. E4412 is a phase 1 ECOG-ACRIN sponsored study of the combination of BV and the checkpoint inhibitors ipilimumab (IPI) and nivolumab (NIVO) in patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL). Here we report the data on the patients treated with BV + IPI, the first cohort of the study. Methods: Patients with biopsy proven R/R HL were treated with BV 1.8mg/kg and two escalating doses of IPI: 1 mg/kg or 3mg/kg. After safety was determined an expanded cohort was treated with BV 1.8mg/kg IV and IPI 3mg/kg IV. The schedule consisted of BV administered every 21 days for 16 cycles and IPI every 21 days x 4 doses and thereafter every 3 months for up to a year. Dose limiting toxicity (DLT) was defined for purposes of dose escalation within the first cycle of therapy. Patients are followed for toxicity up to 30 days beyond their last treatment. Results: As of 7/2015 19 of 23 planned patients have been treated with BV + IPI. We report the data on the full dose escalation population (13 patients: Dose level 1 (6), Dose level 2 (7)). The median age was 33 years (range: 20-49). Seven patients were male. Patients were heavily pretreated with a median of 4 prior therapies (2-13). Fourpatients had prior treatment with BV; 8 patients had prior SCT (7 autologous, 1 allogeneic). Safety: Overall the regimen of BV + IPI was extremely well tolerated with no DLTs noted during dose escalation. Toxicities considered at least possibly related to drug during any cycle of treatment are shown according to grade in Table 1. The most common treatment related adverse events were: diarrhea, rash, and peripheral sensory neuropathy. Other AEs of interest included: alopecia, transaminitis, and uveitis. Grade 3 and 4 treatment related adverse events (AEs) included: Dose level 1: one grade 3 infusion reaction, which led to a protocol amendment to include premedication, no further grade 3 infusion reactions were noted; Dose level 2: one each: grade 3 rash, vomiting, and peripheral sensory neuropathy, and one grade 4 thrombocytopenia in patient with pre-existing thrombocytopenia. Response: For the 12 evaluable patients, the overall response (ORR) for the combination of BV + IPI was 67% with a complete response (CR) rate of 42% (5 of 12 patients). An additional 2 patients had stable disease (SD) giving a clinical benefit rate of 83%. Three of 5 of the CRs occurred at dose level 1 (1mg dose of IPI). The median progression free survival (PFS) is 0.74 years with a median follow-up of 0.66 years. Conclusion: In this first reported study of the combination of checkpoint inhibitor and ADC, toxicity was low, primarily grades 1 and 2. In a heavily pretreated patient population, 33% of whom had had prior BV and 67% of whom were s/p ASCT, the ORR of 67% and CR rate of 42% suggests a potential deepening of response compared to monotherapy. More than half of these CRs occurred at 1mg of IPI suggesting that in combination with ADC, low doses of immune stimulation may be highly active. Optimization of this combination strategy is planned with ongoing accrual to cohorts receiving BV + NIVO, and BV + IPI + NIVO. Data will be updated to include the full BV + IPI cohort by the time of the annual meeting. Table 1.

5543 Background and Purpose: Hypoxia is an adverse prognostic factor in locoregionally advanced cervical cancer treated with radiation. GOG are currently studying the hypoxic cytotoxin, tirapazamine (TPZ) in combination with biweekly intermediate dose cisplatin (CIS) and radiation in a large phase III trial. The aim of this phase I study was to develop a better tolerated regimen that added TPZ to the standard regimen of radiation and weekly low dose CIS. Methods: Eligible patients had previously untreated carcinoma of the cervix, Stages IB2 - IVA. The starting schedule was radiotherapy (45 to 50.4 Gy external beam radiation followed by brachytherapy), with concomitant weekly CIS 40 mg/m2 weeks 1–6 and weekly TPZ 290 mg/m2 (prior to CIS) in weeks 1–5. Results: Between 3/05 and 7/06 eleven patients were enrolled, median age (range) 52 (31–65), squamous cell carcinoma 10, adenocarcinoma 1, 1B2–5, IIA-1, IIB-3, IIIB- 1, IVA-1. The first 2 patients on dose level 1 experienced a dose limiting toxicity (DLT), one grade 3 ALT (SGPT) elevation and grade 4 pulmonary embolism and one grade 3 ototoxicity. Doses were decreased to dose level -1 CIS 30 mg/m2 and TPZ 260 mg/m2. Three patients were treated without any DLTs. Six patients were then treated on dose level -1a, CIS 35 mg/m2 and TPZ 260 mg/m2, with 2 DLTs: grade 3 neutropenia with dose omission and grade 4 pulmonary embolism with major hemodynamic compromise. The sixth patient on dose level -1a withdrew from the trial in week 2 after being advised about the DLTs observed on this dose level. 3 additional patients will be accrued on dose level -1 to confirm safety of this dose level. One patient has relapsed in pelvic nodes, all other patients remain disease-free with a median followup of 10 months (range 5 - 21) Conclusions: The combination of weekly TPZ and CIS with radiation for locally advanced cervical cancer was associated with more toxicity than anticipated with the recommended dose level being TPZ 260 mg/m2, CIS 30 mg/m2.

139 Background: Intraperitoneal (IP) chemotherapy is promising for the treatment of gastric cancer with peritoneal metastasis. We previously verified the safety and efficacy of IP paclitaxel (PTX) combined with S-1 and intravenous (IV) PTX in phase I and phase II studies (Oncology. 2009; Ann Oncol. 2010). Secondly, we developed a new IP-containing chemotherapy regimen, IV PTX plus IP cisplatin (CDDP) and PTX, for patients who have failed S-1-based chemotherapy. We performed a phase I study to determine the maximum-tolerated dose (MTD) and recommended dose (RD) in gastric cancer patients. Methods: A total of 9 gastric cancer patients were enrolled who had shown progression of peritoneal metastasis after S-1-based chemotherapy. PTX was administered intravenously at a dose of 100 mg/m2 and intraperitoneally over 1 hour with an initial dose of 20 mg/m2 (level 1), stepped up to 30 or 40 mg/m2 depending on observed toxicity. CDDP was subsequently administered intraperitoneally at a dose of 30 mg/m2 over 24 hours after PTX infusion. PTX and CDDP were administered on days 1 and 15 in 4-week cycles. Results: At dose level 1, dose-limiting toxicities (DLTs) were observed in 2 of 3 patients. One patient experienced grade 4 leukopenia, and the other grade 3 vomiting. Because of higher toxicities than anticipated, the initial dose-escalation schedule was abandoned, and the doses of IV PTX and IP CDDP were reduced to 80 mg/m2 and 25 mg/m2, respectively, while keeping the dose of IP PTX at 20 mg/m2 (level 0). At dose level 0, one of the first 3 patients experienced grade 3 nausea, and an additional 3 patients experienced no DLTs. Consequently, the MTD and RD were determined to be dose level 1 and dose level 0, respectively. No patients experienced complications related to the peritoneal access device or IP infusion. Conclusions: Combination chemotherapy of IV PTX plus IP CDDP and PTX was shown to be a safe regimen that should be further explored in clinical trials.

144 Background: In Japan, S-1 plus cisplatin is regarded as one of the standard first line treatment of advanced gastric cancer (AGC). However, the prognosis of AGC remains dismal. The development of more effective chemotherapeutic regimen is thus warranted. A combination of irinotecan, cisplatin, and S-1 (IPS) can be a promising triplet therapy for advanced gastric cancer. We conducted a phase I study of IPS to determine the dose-limiting toxicity (DLT), maximum-tolerated dose (MTD) and recommended dose (RD), and to assess its safety and antitumor activity in patients with AGC. Methods: This phase I study was designed and conducted in a 3 + 3 manner to determine the recommended dose (RD) of IPS for the subsequent phase II study. Patients received an escalating dose of intravenous irinotecan (level 1: 100/level 2: 125/level 3: 150 mg/m²) on day 1, a fixed dose of intravenous cisplatin (60 mg/m²) on day 1, a fixed dose of S-1 (80 mg/m² b.i.d.) orally on days 1-14, every 4 weeks. Results: Twelve patients were enrolled between June 2013 and February 2017. During the first cycle, one of the six patients in level 1 and two of six patients in level 2 developed the DLT (grade 4 leucocytopenia and grade 3 febrile neutropenia). The MTD of irinotecan was 125 mg/m 2 (level 2) and the RD of irinotecan was considered to be 100 mg/m² (level 1). The most common grade 3 or 4 adverse events included neutropenia 75 % (9/12), anemia 25% (3/12), anorexia 8% (1/12), and febrile neutropenia 17% (2/12). Among six patients with measurable lesions, the response rate was 66.7% (4/6) [95% CI, 33.3-90.7%]. Two patients were performed R0 resection after IPS, with one patient achieved pathological complete response. The median survival time is under analysis. Conclusions: RD of IPS was determined to be 100 mg/m² of irinotecan, 60 mg/m² of cisplatin, and 80 mg/m² of S-1. Our data showed that this regimen provided acceptable antitumor activity and a favorable toxicity profile. Further evaluation of this regimen is warranted. Clinical trial information: UMIN000006864.

4559 Background: We conducted a phase I dose-finding study of sorafenib (S) in combination with capecitabine (X) and cisplatin (P) in patients with previously untreated metastatic or inoperable advanced gastric cancer. Methods: Four dose levels of S, X, and P combination were tested. The doses of S (p.o. daily), X (p.o. on days 1–14), and P (i.v. on day 1) were escalated at the following schedule; level 1: S 400 mg/d, X 1,600 mg/m2/d, P 80 mg/m2; level 2: S 800 mg/d, X 1,600 mg/m2/d, P 80 mg/m2; level 3: S 800 mg/d, X 2,000 mg/m2/d, P 80 mg/m2; level 1A: S 800 mg/d, X 1,600 mg/m2/d, P 60 mg/m2. The cycle was repeated every 3 weeks. Dose limiting toxicities (DLTs) were evaluated only in the first cycles and a standard 3+3 dose escalation design was implemented. Results: A total 21 pts were enrolled in the study. No DLTs were observed at dose level 1 (n=3). One DLT (grade 3 diarrhea) was noted at dose level 2 (n=6), and 2 DLTs (two grade 4 neutropenias longer than 5 days in duration) were observed at dose level 3 (n=6), which made the level 3 dose the maximum tolerated dose (MTD). However, at cycle 2 and thereafter at dose level 2, the relative dose intensity (RDI) of S and X could not be maintained (mostly below 80%) due to the frequent dose reductions and cycle delays. So, we explored a new dose level (1A) between dose level 1 and 2. Since no DLTs were found in 6 patients at level 1A with RDI mostly above 80% throughout the treatment period, level 1A was determined as recommended dose (RD). Most frequent grade 3 and 4 hematologic toxicities were neutropenia (25.0% of cycles), and most frequent grade 2 and 3 non-hematologic toxicities were hand-foot syndrome (9.4%), asthenia (7.0%), and anorexia (5.5%). The objective responses were confirmed in 10 out of 16 patients with measurable lesions (62.5%; 95% CI, 38.8–86.2%). With a median follow-up of 8.1 months, estimated median progression-free survival was 10.0 months (95% CI, 1.6–18.4 months) and median overall survival has not been reached. Conclusions: Diarrhea and neutropenia were DLTs in this S, X, and P combination. The dose schedule of sorafenib 400 mg po bid daily with capecitabine 800 mg/m2 po bid on days 1–14, and cisplatin 60 mg/m2 iv on day 1 in every 3 weeks is recommended for further development in AGC.
