BackgroundCombination chemotherapy is associated with improved outcomes in trials of selected fit patients with advanced colorectal cancer (acrc). For older or less-fit patients, combination chemotherapy is associated with greater toxicity and less benefit. Capecitabine monotherapy is a reasonable option for those patients, but the optimal dose remains controversial.MethodsA multicentre phase i/ii trial of reduced-dose capecitabine (2000 mg/m2, days 1–14 every 21 days) was conducted in 221 patients representing one or more of the following subsets: age greater than 65 years (n = 167), Eastern Cooperative Oncology Group (ecog) performance status of 1 or greater (n = 139), elevated lactate dehydrogenase (ldh) (n = 105), or prior pelvic radiation (n = 54). Based on phase i results, patients with prior pelvic radiation received capecitabine 750 mg/m2 twice daily. The goal was to ascertain efficacy in a design that was unlikely to cause high levels of toxicity.Results Median age in the patient cohort was 72 years. A median of 5 and a mean of 8 capecitabine cycles were given (range: 0–50 cycles). Grade 3 or 4 toxicity occurred in 25% of patients during the first 3 cycles (8.1% hand–foot syndrome, 7.7% diarrhea). The response rate was 13.6%, with a 69.7% disease control rate. Median progression-free survival (pfs) was 5.6 months. Post progression, 56 patients received further capecitabine monotherapy (median of 4 additional cycles). Median overall survival duration for the patients was 14.3 months. Median survival was significantly higher for those who, at baseline, had an ecog performance status of 0 (compared with 1 or more) and normal ldh (compared with elevated ldh).Conclusions Toxicity is less with dose-reduced capecitabine than with historical full-dose capecitabine, with only a small trade-off in efficacy, seen as a lower objective response rate. The improved tolerability could lead to an increased number of cycles of therapy, and pfs appears to be consistently higher at the lower dose. Those observations should, in the absence of a head-to-head clinical trial, be viewed as compelling evidence that 1000 mg/m2, or even 750 mg/m2, twice daily is an appropriate dose in elderly or frail patients with acrc.

PURPOSE To evaluate the activity and toxicity of combined high-dose cisplatin, dacarbazine (DTIC), and tamoxifen chemotherapy and high-dose bolus interleukin-2 (IL-2) in patients with metastatic melanoma. PATIENTS AND METHODS Patients with metastatic melanoma, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and normal organ function were enrolled onto this multiinstitutional Cytokine Working Group trial. Patients received intensive chemoimmunotherapy consisting of cisplatin (50 mg/m2) and DTIC (350 mg/m2) intravenously (IV) on days 1 to 3 and 43 to 45, IL-2 600,000 IU/kg IV every 8 hours on days 12 to 16 and 26 to 30 (maximum, 28 doses), and tamoxifen 20 mg orally each day. Patients were evaluated for response at day 63 of each cycle, and responding patients were given a second cycle of therapy beginning on day 71 to 85. RESULTS Thirty-eight patients were entered onto this study. Toxicities were as expected for the chemotherapy and immunotherapy components of this regimen. Overlapping toxicity consisted primarily of thrombocytopenia (76% of patients required platelet transfusions), neutropenia, anemia, fatigue, and weight loss. Despite these cytopenias, bleeding and infectious complications were rare. There were no treatment-related deaths. Three patients achieved a complete response (CR; 8%), and 13 achieved a partial response (PR). The overall objective response rate was 42% (95% confidence interval [CI], 26% to 58%). Six additional patients had greater than 50% tumor reduction at day 63, which did not persist until a subsequent evaluation. The median duration of response was 5 months (range, 2 to 20+), and the median survival duration was 11 months. CONCLUSION This intensive treatment regimen appears to possess activity in metastatic melanoma comparable, but not superior, to that of other less intensive cisplatin- and IL-2-based chemoimmunotherapy regimens. Although the toxicity and complexity of this regimen make it unsuitable for phase III testing and impractical for more widespread use, the results of this study support a potential favorable interaction between IL-2 and chemotherapy in this disease and highlight the need for appropriately designed phase III trials.

TPS3636 Background: Colorectal cancer (CRC) is the second leading cause of cancer-related death in western countries. With advances in the treatment of metastatic CRC (mCRC) in the last decade using combination chemotherapy and bevacizumab, a monoclonal antibody against the vascular endothelial growth factor (VEGF), progression free survival (PFS) in first and second line setting was substantially improved. Tumour angiogenesis is also driven by other factors but VEGF including Platelet Derived Growth Factor (PDGF) and Fibroblast Growth Factor (FGF). BIBF1120 is a potent, orally available triple angiokinase inhibitor that blocks the receptor tyrosine kinase activity of human VEGFR1-3, FGFR1 and -3 and PDGFRα and -β. Thus, BIBF1120 could be an exciting addition to the treatment of patients with chemorefractory CRC. Methods: Randomized, double-blind, placebo-controlled, multicentre, phase II trial of BIBF1120 (orally, 200 mg, bid, d1-d14, Arm A) vs. placebo (Arm B) in patients receiving mFOLFOX6 (oxaliplatin, 85 mg/m2, fluorouracil, 400 mg/m2 bolus and 2400 mg/m2 over 46 h, leucovorin, 200 mg/m2) q14 d for patients (ECOG performance status 0-1) with chemorefractory mCRC who received one prior line of chemotherapy. Scheduled are 90 patients per treatment arm. Primary endpoint: PFS, Secondary endpoints: objective response, overall survival, duration of overall response, safety. Additionally there will be an explorative analysis of predictive biomarkers for BIBF1120. 4 of planned 180 patients have been enrolled. We expect the last patient out in June 2013.

752 Background: XELIRI plus bevacizumab (Bev) might be one of the standard therapies for metastatic colorectal cancer (mCRC). However, there was no clinical practice data in Japan. This study was designed to evaluate the efficacy and safety of XELIRI plus Bev in clinical practice in Japanese mCRC patients (pts.). Methods: This was a multicenter, single-arm, open-label prospective study. The major inclusion criteria were previously untreated mCRC; presence of measurable lesions; age ≥20 years; ECOG performance status (PS) of 0–2; and adequate organ function. Pts received Bev 7.5 mg/kg day 1 and XELIRI (irinotecan 200 mg/m2 day 1 plus capecitabine 800 mg/m2 bid d1-14) q3w. This schedule was repeated until unacceptable toxicity or disease progression occurred. The primary endpoint was RECIST-confirmed objective response rate (ORR). A sample size of 35 was planned for a threshold ORR of 30% and expected value of 53%, with one-sided alpha of 0.05 and beta of approximately 0.2. Results: A total of 36 pts (male/female, 23/13; median age, 65.0 years (range 44.0-80.0); PS 0/1/2, 31/5/0) were enrolled in this study from July 2011 to September 2012. One patient did not fulfill the eligibility criteria and one withdrew the informed consent before the start of protocol treatment. Thirty-four pts were assessed for response; CR 0, PR 18, SD 9, PD 4, and NE 3. The confirmed ORR was 52.9% (90% CI, 37.7-67.8%). Median PFS was 9.6 months (95% CI, 5.1-11.1 months) and mOS was 23.0 months (95% CI, 11.3-NE months). mTTF was 5.3 months (95% CI, 3.2-8.3 months). The most common grade 3/4 adverse events were neutropenia 31.4%, anemia 20.0%, thrombocytopenia 5.7%, hyponatremia 20.0%, anorexia 20.0%, diarrhea 22.8%, fatigue 0.0%, hypertension 2.9%, hand-foot syndrome 0.0%, and bleeding 0.0%. Conclusions: First-line treatment of XELIRI + Bev showed a promising response rate and an acceptable tolerability profile in the clinical practice in Japanese mCRC pts.

PURPOSE To provide an investigational drug, paclitaxel, now commercially available, to women with refractory ovarian cancer and to evaluate response and toxicity in these patients. PATIENTS AND METHODS Patients with platinum-refractory ovarian cancer, Eastern Cooperative Oncology Group (ECOG) performance status 0 to 3, at least three prior chemotherapy regimens, adequate hepatic and renal function, and no significant cardiac history were eligible. Patients were treated with paclitaxel 135 mg/m2 administered by 24-hour continuous intravenous infusion every 3 weeks. RESULTS Leukopenia was the most frequent toxicity, with 78% of patients experiencing grade 3 or 4 toxicity. Other grade 3 and 4 toxicities were less common: fever (33%), infection (12%), thrombocytopenia (8%), vomiting (7%), cardiac (2%), neurologic (2%), and mucositis (1%). Fifteen treatment-related deaths (1.5%) were reported. The objective response rate was 22% (4% complete response [CR], 18% partial response; 95% confidence interval [CI] for overall response, 19% to 25%). The median time to progression from treatment initiation was 7.1 months in responding patients and 4.5 months for all patients. The median survival duration was 8.8 months. CONCLUSION Paclitaxel has shown activity in women with platinum-refractory ovarian cancer, and it can be administered with an acceptable safety profile. Further research is needed to determine the optimal role of paclitaxel in the primary and salvage treatment of ovarian cancer.

Based on the reports of activity of interferons against metastatic melanomas, we conducted a phase II study of recombinant interferon alfa-2a (Roferon-A, Hoffmann-La Roche, Nutley, NJ) in 66 patients with disseminated melanoma. All patients had excellent Eastern Cooperative Oncology Group (ECOG) performance status (0 to 1), and no evidence of brain metastases. Thirty patients had previously received chemotherapy and the remainder were untreated. The first 35 patients were treated on a daily schedule starting with a Roferon-A dose of 3 X 10(6) U/d and escalating to a maximum of 36 X 10(6) U/d over a period of 12 days. Because of excessive toxicity, the second group of 31 patients were treated on a fixed dose of 18 X 10(6) U/d [corrected] three times weekly (TIW). Among the 62 evaluable patients, five achieved an objective response for a response rate of 8% (95% confidence limits, 3% to 18%). Four patients had minor regressions and eight patients had stability of disease. The responses were evenly distributed between the two dose schedules. The major toxicity of interferon consisted of a constitutional syndrome of anorexia, fever, weight loss, and fatigue, which required a dose reduction in 75% of the patients on the daily schedule. Our data revealed a modest level of activity, which was not influenced by prior treatment or by the dose or schedule of interferon. Because of substantial toxicity with the daily schedule, we recommend a dose of 18 X 10(6) U/d [corrected] if interferon is used in the treatment of patients with melanoma.

This study investigated the antitumor activity and safety of pembrolizumab in patients with recurrent cervical cancer in real-world practice. We conducted a multi-center retrospective study of patients with recurrent or persistent cervical cancer treated with pembrolizumab at sixteen institutions in Korea between January 2016 and March 2020. The primary endpoints were the objective response rate (ORR) and safety. Data were available for 117 patients. The median age was 53 years (range, 28–79). Sixty-four (54.7%) patients had an Eastern Cooperative Oncology Group (ECOG) performance status of ≥2. Forty-nine (41.9%) patients were stage ≥III at diagnosis. Eighty-eight (75.2%) patients had squamous cell carcinoma. The median number of prior chemotherapy lines was two (range, 1–6). During the median follow-up of 4.9 months (range, 0.2–35.3), the ORR was 9.4%, with three complete responses and eight partial responses. The median time to response was 2.8 months (range 1.3–13.1), and the median duration of response (DOR) was not reached. In the population of patients with favorable performance status (ECOG ≤1) (n = 53), the ORR was 18.9%, and the median DOR was 8.9 months (range, 7.3–10.4). Adverse events occurred in 55 (47.0%) patients, including eight (6.8%) patients who experienced grade ≥3 events, and two of them were suspicious treatment-related deaths. Pembrolizumab had modest antitumor activity in patients with recurrent cervical cancer comparable to that found in previously reported clinical trials. However, in patients with favorable performance status, pembrolizumab showed effective antitumor activity. Some safety profiles should be carefully monitored during treatment.

PURPOSE To assess the efficacy of irinotecan (CPT-11) in the treatment of advanced colorectal cancer in both chemotherapy-naive and pretreated patients. PATIENTS AND METHODS Two hundred thirteen patients (aged 18 to 75 years) with metastatic colorectal cancer, World Health Organization (WHO) performance status < or = 2, and life expectancy > or = 3 months were treated with CPT-11 350 mg/m2 every 3 weeks. All 178 patients eligible for efficacy analysis had not received more than one prior fluorouracil (5-FU)-based chemotherapy regimen (adjuvant or palliative) and had adequate hematologic, renal, and hepatic function. RESULTS Primary tumor sites were the colon (71%) and rectum (28%). Sixty-six percent of the patients had > or = two metastatic sites. Ninety-eight percent of the patients had undergone previous surgery, and 77.5% had received prior chemotherapy. Thirty-two of 178 eligible patients achieved on objective response (four complete responses [CRs] and 28 partial responses [PRs]; response rate, 18%; 95% confidence interval, 12.6% to 24.4%), 65 were stable, and 59 progressed. The response rate was 17.7% in the pretreated group and 18.8% in the chemotherapy-naive group. Within the former subgroup, response rates of 16.1% were reported in patients who were progressive on prior 5-FU chemotherapy and 19.1% in patients who were progressive off such treatment. The median duration of objective response (9.1 months) and median time to achievement of a response (9.3 weeks) did not differ between chemotherapy-naive and pretreated patients. The most frequent adverse events were neutropenia, which developed in 80% of the patients, delayed diarrhea (87%), alopecia (88%), fatigue (81%), and nausea/vomiting (77%). All these adverse events were manageable. Severe (WHO grade 3 or 4) neutropenia was only observed in 18% of the cycles, leukopenia in 11%, delayed diarrhea in 11%, and nausea and vomiting in 3%. Development of simultaneous grade 3 or 4 neutropenia and delayed diarrhea during 4% of the cycles was the safety issue of greatest concern. CONCLUSION CPT-11 has definite activity in the treatment of advanced metastatic colorectal cancer both in chemotherapy-naive and in pretreated patients who experienced disease progression on 5-FU, which suggests a lack of cross-resistance between CPT-11 and 5-FU. Diarrhea and neutropenia, the major toxicities of CPT-11, contribute to the risk to develop febrile neutropenic sepsis.

14599 Background: We prospectively conducted a phase II trial to test the efficacy and safety of irinotecan, 5-fluorouracil and leucovorin (FOLFIRI) regimens for the first-line treatment of previously untreated patients with recurrent or metastatic advanced CRC. Methods: Thirty-four previously untreated patients with advanced CRC were enrolled in this study from June 2001 to December 2006. Eligible patients had histologically confirmed adenocarcinoma, no prior systemic therapy in palliative setting, ECOG PS = 2, adequate organ function, written informed consent and at least one measurable disease. The patients received either irinotecan 180 mg/m2 on day 1 with a LV bolus of 200 mg/m2 and a FU bolus of 400 mg/m2, and this was followed by a FU continuous infusion of 600 mg/m2 on day 1 and day 2 (the classic FOLFIRI regimen), or they were treated with a LV bolus of 400 mg/m2 and a FU bolus of 400 mg/m2 followed by a FU continuous infusion of 2,400 mg/m2 for 46 hours (the simplified FOLFIRI regimen), and these treatments were repeated every 2 weeks until disease progression. Results: There were 13 females and 21 males with median age of 54 years (range: 41–79). The most common metastatic sites were lung and liver. A total of 262 cycles were administrated with median 6 cycles per patient (range: 1–22). All pts were evaluable for toxicity, and 30 pts for response to the treatment. The objective response rate was 26.4% with 2 complete responses respectively. Sixteen (47%) pts had stable disease and 7 (20.5%) had a progression. The tumor control rate was 73.4%. The median TTP was 5.3 months, and the overall survival was 10.1 months. The prognostic factor for longer TTP and survival was the ECOG performance status (PS). The type of regimens was not affected on response rate, TTP and survival. The chemotherapy was generally well tolerated and the most common grade 3–4 toxicities were neutropenia, diarrhea. The non- hematological toxicities were similar for both treatment groups, with more frequent grade =3 neutropenia being noted for the simplified FOLFIRI regimen. Conclusions: The FOLFIRI regimen was demonstrated to have a moderate antitumor activity with acceptable toxicity profiles, and tend to show more favorable outcome for patients with good ECOG PS. No significant financial relationships to disclose.

18011 Background: Recurrent SCLC has a poor prognosis and is devoid of treatment options that improve overall survival. Irinotecan and paclitaxel are both active agents against SCLC, and have synergistic preclinical interactions. We conducted a phase II study to evaluate the efficacy and safety of the combination of irinotecan and paclitaxel for patients with recurrent SCLC. Methods: Patients with SCLC who relapsed following one prior chemotherapy regimen were eligible. Other pertinent inclusion criteria were: ECOG performance status 0–2, adequate bone marrow, hepatic and renal function and willingness to provide informed consent. Patients with untreated brain metastasis were excluded. Paclitaxel (75 mg/m2) and irinotecan (50 mg/m2) were administered on days 1 & 8 of every 3-week cycle. Treatment was continued until progression up to a maximum of 6 cycles or unacceptable toxicity. The primary endpoint was response rate. Toxicity was graded by CTC version 2.0. The simon two-stage design was utilized and the estimated sample size was 55 patients (stage I - 23 patients; stage 2 - 32 patients). The study has a 90% power to detect a response rate of 30%, with an alpha error rate of 10%. Results: 55 patients have been enrolled and complete data are available for 32 patients at the time of this report. Patient baseline characteristics are: male 53%, PS 0–44%; PS 1–47% and PS 2–6%. The median age is 61 years. Fifteen patients received ≥ 4 cycles. Salient grades 3–5 toxicities seen: neutropenia (13%), fatigue (13%); diarrhea (3%), hypersensitivity (3%) and hyponatremia (3%).The objective response rate is 37% (95% CI 19%-55%) with 9 PRs and 1 CR. Additional 8 patients (24%) had stable disease. The median survival is 19.6 weeks (95% CI 15.1–29.4) and the 1-year survival rate is 15%. Conclusions: The combination of irinotecan and paclitaxel is well tolerated and has promising anti-cancer activity in recurrent SCLC. Updated data on all 55 patients will be available at the time of the presentation. No significant financial relationships to disclose.

3521 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI provided robust and durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up data will be presented. Methods: Patients with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg every 2 weeks + low-dose IPI 1 mg/kg every 6 weeks until disease progression or discontinuation. The primary endpoint was investigator-assessed objective response rate (ORR). Results: For all 45 patients (median follow-up was 13.8 months), ORR was 60% (95% CI 44.3–74.3). Responses were consistent with the overall population across subgroups including age, Eastern Cooperative Oncology Group (ECOG) performance status, prior adjuvant/neoadjuvant therapy, and mutation status (Table). Seven patients (16%) had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had any grade TRAEs leading to discontinuation. Updated response, survival, and safety data after a longer follow-up (median 19.9 months) will be presented. Conclusions: NIVO + low-dose IPI demonstrated robust and durable clinical benefit and was well tolerated. Evaluated subgroups had responses consistent with the overall population. NIVO + low-dose IPI may represent a new 1L treatment option for patients with MSI-H/dMMR mCRC. Clinical trial information: NCT02060188. [Table: see text]
