PurposeTo evaluate the efficacy and safety of ixabepilone in patients with metastatic breast cancer (MBC) resistant to anthracycline, taxane, and capecitabine, in this multicenter, phase II study.Patients and MethodsPatients with measurable disease who had tumor progression while receiving prior anthracycline, taxane, and capecitabine were enrolled. Ixabepilone 40 mg/m2monotherapy was administered as a 3-hour intravenous infusion on day 1 of a 21-day cycle. The primary end point was objective response rate (ORR), assessed by an independent radiology facility (IRF).ResultsA total of 126 patients were treated and 113 were assessable for response. Patients were heavily pretreated: 88% had received at least two lines of prior chemotherapy in the metastatic setting. IRF-assessed ORR was 11.5% (95% CI, 6.3% to 18.9%) for response-assessable patients. Investigator-assessed ORR for all treated patients was 18.3% (95% CI, 11.9% to 26.1%). Fifty percent of patients achieved stable disease (SD); 14.3% achieved SD ≥ 6 months. Median duration of response and progression-free survival were 5.7 and 3.1 months, respectively. Median overall survival was 8.6 months. Patients received a median of 4.0 treatment cycles (range, one to 16 cycles), and 25% of patients received ≥ eight cycles. Grade 3/4 treatment-related events included peripheral sensory neuropathy (14%), fatigue/asthenia (13%), myalgia (8%), and stomatitis/mucositis (6%). Resolution of grade 3/4 peripheral sensory neuropathy occurred after a median period of 5.4 weeks.ConclusionIxabepilone demonstrated clear activity and a manageable safety profile in patients with MBC resistant to anthracycline, taxane, and capecitabine. Responses were durable and notable in patients who had not previously responded to multiple prior therapies.

18179 Background: Because elderly pts may tolerate platinum-based combination chemotherapy poorly, single-agent chemotherapy is selected for the treatment regimen. However, retrospective subgroup analyses have consistently indicated that elderly pts indeed benefit from platinum-based combination chemotherapy as well as their younger counterparts. This phase II study evaluated the efficacy and safety of carboplatin-gemcitabine combination chemotherapy in elderly pts with advanced NSCLC. Methods: Fifty-four pts aged more than 70 years old (median, 77; range, 70–88) with previously untreated advanced NSCLC were enrolled on this trial. Additional criteria included the presence of measurable lesions, an Eastern Cooperative Oncology Group performance status of 0 or 1, and adequate organ function. Pts received carboplatin at an area under the curve of 4 mg/ml/min on the first day and gemcitabine at 1000 mg/m2 on the first and eighth day of consecutive 3 week periods. The primary endpoint was to determine the objective response rate of this platinum-doublet regimen. The RECIST criteria were used to measure response. Results: Enrolled pts included 15/39 with stage IIIB/IV diseases. Fifty-one out of enrolled pts were eligible for efficacy and safety analyses. The median number of treatment cycles was 4 (range, 1–7). Fifteen partial responses (response rate: 29%) were obtained. The median TTP was 118 days. Hematological toxicities of grade 3/4 included leukopenia (46%), neutropenia (72%) and thrombocytopenia (50%). Non-hematological toxicities of grade 3/4 included nausea (6%), appetite loss (7%), fatigue (7%) and infection (9%). Conclusions: The combination carboplatin-gemcitabine at these doses has shown activity with a favorable toxicity profile for fit elderly pts with advanced NSCLC.

Background: Standard intravenous (IV) paclitaxel is associated with hypersensitivity/toxicity. Alternative IV formulations have improved tolerability but still require frequent hospital visits and IV infusion. DHP107 is a novel oral formulation of paclitaxel that is approved in South Korea for the treatment of gastric cancer. Methods: This multicenter, phase II study using a Simon’s two-stage design investigated the efficacy and safety of DHP107 200 mg/m2 administered orally twice daily on days 1, 8, and 15 every 4 weeks for the first-line treatment of recurrent or metastatic HER2-negative breast cancer. Results: Thirty-six patients were enrolled and 31 were assessable for efficacy. Patient median age was 57 years (range = 34–81) and 11 (31%) had triple-negative disease. A median of seven cycles (range = 1–28) of DHP107 was administered. Objective response rate was 55% (17 patients), all partial responses, according to the investigator’s decision and independent central review (ICR), and 44% (4/9 patients) in those with triple-negative disease. Disease control rate (partial response and stable disease) was 74% (23 patients) according to the investigator’s decision and ICR. In the intention-to-treat (ITT) population of all enrolled participants, the objective response rate was 50% (18/36 patients). Median progression-free survival was 8.9 months [95% confidence interval [CI]: 5.2–12.3) and median time to treatment failure was 8.0 months (95% CI: 4.2–10.0). DHP107 had an acceptable toxicity profile. All patients experienced treatment-emergent adverse events; the most common adverse events were decreased neutrophil count (81% all grades and 78% grade ⩾ 3) followed by peripheral sensory neuropathy (61% all grades and 8% grade 3). However, there was no febrile neutropenia or sepsis. Conclusion: DHP107 showed promising efficacy and acceptable tolerability in this phase II study and is currently being investigated in the OPTIMAL phase III study (NCT03315364). Trial registration: This trial was registered with ClinicalTrials.gov identifier: NCT03315364.

4076 Background: Previous phase II study showed a high efficacy and safety of FOLFOXIRI (irinotecan, oxaliplatin, 5-fluorouracil, leucovorin) combination chemotherapy in metastatic colorectal cancer. This non-randomized open label phase II study evaluated the efficacy and safety of FOLFOXIRI in metastatic or recurrent gastric cancer patients. Methods: Patients with: histologically proven, bidimensionally measurable, metastatic gastric adenocarcinoma, age 18 - 70 years, with a performance status 0 - 2, no prior chemotherapy or at least 12 months after adjuvant therapy, life expectancy > 3 months, signed written informed consent were eligible. Treatment consisted of irinotecan 150 mg/m2 day 1, oxaliplatin 85 mg/m2 day 1, leucovorin 100 mg/m2 day and 5-fluorouracil 2000 mg/m2 as a 48-h continuous infusion starting on day 1, repeated every 2 weeks until unacceptable toxicity, patients’ refusal, or up to 12 cycles. The planned sample size was 48 and the primary endpoint was response rate. Results: From August 2004 to August 2005, 48 patients were prospectively enrolled. The median age was 54 years (24 - 69) and male:female ratio was 1.3:1. In total, 379 cycles were administered with a median of 9 cycles per patient (range, 1–12) and 45/48 patients were evaluable for treatment response. Three patients were not assessable for response due patients’ refusal for further chemotherapy following the first cycle. By per-protocol analysis, the objective response rate was 73.3 % (95% CI, 60.8–85.8) with 2 CRs and 31 PRs. Four patients (9%) had stable disease and 8 patients (18%) had progressive disease. The estimated median survival of all patients was 14.0 months (95% CI, 11.8 - 16.2 ) and the estimated median time-to-progression was 8.9 months (95% CI, 6.7–11.0). In total of 379 cycles administered, most common grade 3/4 toxicities were neutropenia (11% of all cycles) and emesis (12%). Grade 2 peripheral neuropathy occurred in 5 patients. One (2%) patient had severe tumor bleeding and 5 (10%) patients experienced grade 3 diarrhea. Conclusions: FOLFOXIRI combination chemotherapy showed a very promising preliminary anti-tumor activity and was generally well tolerated as a first-line treatment for patients with metastatic gastric cancer.

PURPOSE: This pilot phase II study investigated the efficacy and toxicity of docetaxel with doxorubicin and cyclophosphamide (TAC) as first-line chemotherapy for anthracycline-naive patients with metastatic breast cancer. PATIENTS AND METHODS: Fifty-four patients received a total of 359 courses consisting of docetaxel 75 mg/m2 given intravenously (IV) over 1 hour, preceded by IV doxorubicin 50 mg/m2 and cyclophosphamide 500 mg/m2 for a maximum of eight 3-week cycles. RESULTS: After an independent panel review, the overall objective response rate was 77% (complete response, 6%). Overall objective response rates in patients with visceral, bone, and liver involvement were 82%, 82%, and 80%, respectively. Median duration of response was 52 weeks, and median time to progression was 42 weeks. With a median follow-up of 32 months, the median survival had not yet been reached, whereas the 2-year survival was 57%. The main toxicities were hematologic (neutropenia grade 3/4 in 100% of patients and 95% of cycles; febrile neutropenia in 34% of patients and 9% of cycles). Documented grade 3 infection was seen in one patient (2%) in one cycle, and no toxic death was reported. Severe acute or chronic nonhematologic adverse events were infrequent, and docetaxel-specific toxicities (such as fluid retention and nail changes) were mild, with only one patient being discontinued for fluid retention. Congestive heart failure was seen in two patients (4%). CONCLUSION: TAC is an active and manageable regimen that has been chosen as the basis of five randomized phase III trials, including two pivotal studies comparing TAC to fluorouracil plus doxorubicin and cyclophosphamide in the metastatic and adjuvant treatment of breast cancer.

90 Background: ABI-007 is a novel Cremophor-free nanoparticle albumin-bound paclitaxel. Cremophor-free formulation allows administration using a shorter infusion schedule (30 minutes) and without the need for premedicaion to prevent solvent-based hypersensitivity reactions.This single arm phase II study evaluated the efficacy and safety of ABI-007 given every three weeks to unresectable or recurrent gastric cancer patients (pts) who had received one prior chemotherapy regimen containing fluoropyrimidine and developed disease progression (PD) or recurrence. Methods: Eligibility include: histologically or cytologically confirmed gastric adenocarcinoma , received one prior regimen containing fluoropyrimidine analogs and developed PD or recurrence, age: 20 - 74, at least one measurable lesion by RECIST(1.0), PS:0-2, adequate organ function and written informed consent. Study duration was until PD or unacceptable toxicity developed. Pts received ABI-007 260 mg/m2, i.v. on day 1 of each 21 day cycle) without premedication. The primary endpoint was overall objective response rate (ORR). Results: From April 2008 to July 2010, total of 56 pts were enrolled, 55 received the study treatment, and 54 pts were evaluable for response. Median age was 64, Male/Female was 43/12, PS:0/1/2 was 33/22/0 and number of sites of metastasis corresponding was 1/2/≥3:19/21/15. ORR was 27.8% (15/54; 95%CI, 16.5-41.6) and DCR (disease control rate:CR+PR+SD) was 59.3% (32/54, 95%CI, 45.0-72.4) for all evaluable patients. One confirmed CR was observed. Median progression–free survival was 2.9 months (95%CI, 2.4-3.6), and median overall survival was 9.0 months (95%CI, 6.6-11.5). The most common grade 3/4 toxicities were neutropenia (49.1%), leucopenia (20.0%), lymphopenia (10.9%); and peripheral sensory neuropathy (23.6%). Conclusions: These data demonstrate that ABI-007 showed promising activity with well-tolerated toxicities for previously treated unresectable or recurrent gastric cancer pts.

136 Background: Nanoparticle Albumin-Bound Paclitaxel (nab-PTX) is a new solvent free taxane-based anticancer drug. According to CA024 trial, nab-PTX 100mg/m2 demonstrated superior response to docetaxel (DTX) in patients with metastatic breast cancer. Besides, nab-PTX 100mg/m2 was less toxicity. In operable breast cancer, GeparSepto study was reported that the pCR rate were significantly higher with nab-PTX 125/150 mg/m2 compared to paclitaxel. We planned the randomized parallel design phase II trial to evaluate nab-PTX 100mg/m2in early breast cancer. Methods: Stage II-III HER2-negative breast cancer patients were included in this trial and received either 4 cycles of DTX (75 mg/m2 day1) q 3 w or 4 cycles of nab-PTX (100 mg/m2 day1/8/15) q4w followed by 4 cycles of FE100C. The primary end point is pCR (ypT0/is ypN0) rate, and the secondary end points are response rate, histological effect of treatment, breast conservation rate, and toxicity. Results: Between March 2011 to March 2014, 152 eligible patients were enrolled at 6 centers (75 pts were allocated for nab-PTX). Baseline characteristics were well balanced; median age was 51/49 years (DTX/nab-PTX), 61/61% of the patients with ER positive, 38/36% triple negative breast cancer, 57/65% Ki67 > 20%. Clinically response rate was similar to each drug. (53/57%) The pCR rate was 12/17% (p = 0.323). In TNBC group, the pCR rate was 28/30% (p = 0.866). In Ki67 > 20% group, the pCR rate was significantly higher, 16/48% (p = 0.021) with nab-PTX arm. The most common grade3-4 adverse event was neutropenia, which was observed in 40/36% of cases. Non-hematological adverse events of any grade were; 34/32% myalgia (DTX/nab-PTX), 42/35% arthralgia, 55/65% peripheral sensory neuropathy. No Grade3-4 peripheral sensory neuropathy was observed in nab-PTX arm. Infusion reaction of DTX occurred in 1 patient. Conclusions: In this initial effectively analysis, neoadjuvant weekly nab-paclitaxel 100mg/m2 were promising drug in HER2-negative operable breast cancer patients. Larger studies will be needed to evaluate neoadjuvant weekly nab-paclitaxel compared with DTX. Clinical trial information: 000005388.

PURPOSE Olaparib, a poly (ADP-ribose) polymerase (PARP) inhibitor (PARPi), is approved for the treatment of human epidermal growth factor receptor 2 (HER2)–negative metastatic breast cancer (MBC) in germline (g) BRCA1/ 2 mutation carriers. Olaparib Expanded, an investigator-initiated, phase II study, assessed olaparib response in patients with MBC with somatic (s) BRCA1/ 2 mutations or g/s mutations in homologous recombination (HR)–related genes other than BRCA1/2. METHODS Eligible patients had MBC with measurable disease and germline mutations in non- BRCA1/ 2 HR-related genes (cohort 1) or somatic mutations in these genes or BRCA1/ 2 (cohort 2). Prior PARPi, platinum-refractory disease, or progression on more than two chemotherapy regimens (metastatic setting) was not allowed. Patients received olaparib 300 mg orally twice a day until progression. A single-arm, two-stage design was used. The primary endpoint was objective response rate (ORR); the null hypothesis (≤ 5% ORR) would be rejected within each cohort if there were four or more responses in 27 patients. Secondary endpoints included clinical benefit rate and progression-free survival (PFS). RESULTS Fifty-four patients enrolled. Seventy-six percent had estrogen receptor–positive HER2-negative disease. Eighty-seven percent had mutations in PALB2, s BRCA1/ 2, ATM, or CHEK2. In cohort 1, ORR was 33% (90% CI, 19% to 51%) and in cohort 2, 31% (90% CI, 15% to 49%). Confirmed responses were seen only with g PALB2 (ORR, 82%) and s BRCA1/ 2 (ORR, 50%) mutations. Median PFS was 13.3 months (90% CI, 12 months to not available/computable [NA]) for g PALB2 and 6.3 months (90% CI, 4.4 months to NA) for s BRCA1/ 2 mutation carriers. No responses were observed with ATM or CHEK2 mutations alone. CONCLUSION PARP inhibition is an effective treatment for patients with MBC and g PALB2 or s BRCA1/ 2 mutations, significantly expanding the population of patients with breast cancer likely to benefit from PARPi beyond g BRCA1/ 2 mutation carriers. These results emphasize the value of molecular characterization for treatment decisions in MBC.

PURPOSE Docetaxel (Taxotere, Rhone-Poulenc Rorer, Antony, France) and cisplatin are two of the most active single agents used in the treatment of non-small-cell lung cancer (NSCLC). A recently reported phase I study of the combination of docetaxel and cisplatin recommended a dose of 75 mg/m2 of both drugs every 3 weeks for subsequent phase II study. PATIENTS AND METHODS Eligible patients were aged 18 to 75 years with a World Health Organization (WHO) performance status < or = 2 and life expectancy > or = 12 weeks, with metastatic and/or locally advanced NSCLC proven histologically or cytologically. Patients were not permitted to have received prior chemotherapy, extensive radiotherapy, or any radiotherapy to the target lesion and must have had measurable disease. Concurrent treatment with colony-stimulating factors (CSFs) or prophylactic antibiotics was not permitted. Docetaxel (75 mg/m2) in 250 mL 5% dextrose was given intravenously (i.v.) over 1 hour immediately before cisplatin (75 mg/m2) in 500 mL normal saline given i.v. over 1 hour in 3-week cycles. Premedication included ondansetron, dexamethasone, promethazine, and standard hyperhydration with magnesium supplementation. RESULTS A total of 47 patients, two thirds of whom had metastatic disease, were entered onto this phase II study. The majority of patients were male (72%) and of good (WHO 0 to 1) performance status (85%). All 47 patients were assessable for toxicity and 36 were for response. Three patients were ineligible and eight (17%) discontinued treatment because of significant toxicity. In assessable patients, the overall objective response rate was 38.9% (95% confidence limits [CL], 23.1% to 56.5%), 36.1% had stable disease, and 25% progressive disease. On an intention-to-treat analysis, the objective response rate was 29.8%. Median survival was 9.6 months and estimated 1-year survival was 33%. Significant (grade 3/4) toxicities included nausea (26%), hypotension (15%), diarrhea (13%), and dyspnea mainly related to chest infection (13%). One patient experienced National Cancer Institute (NCI) grade 3 neurosensory toxicity after eight cycles. Grade 3/4 neutropenia was common and occurred in 87% of patients, but thrombocytopenia > or = grade 3 was rare (one patient). Significant (grade 3/4) abnormalities of magnesium levels were common (24%). Febrile neutropenia occurred in 13% of patients and neutropenic infection in 11%, contributing to two treatment-related deaths. No neutropenic enterocolitis or severe fluid retention was reported. CONCLUSION Compared with other active regimens used in this setting, the combination of docetaxel and cisplatin in advanced NSCLC is an active regimen with a similar toxicity profile to other combination regimens.
