Abstract Neutropenia is common in patients receiving myelotoxic chemotherapy. Benefilgrastim, an rhG-CSF dimer (rhG-CSF-FC fusion protein), is a once-per-cycle therapy for prophylactic neutrophil support. In this Phase II trial, 230 women with stage I-IV breast cancer are to be treated for 4 chemotherapy cycles with either docetaxel/cyclophosphamide (TC) or doxorubicin/docetaxel/cyclophosphamide (TAC) chemotherapy, with each cycle lasting approximately 21 days. Patients will be randomized to receive either benefilgrastim or pegfilgrastim (Neulasta; 6 mg fixed dose) one day after chemotherapy during each cycle, as a subcutaneous injection. Dose levels of benefilgrastim examined are 80 µg/kg (TC patients only), and 240 and 320 µg/kg (TC and TAC patients). The primary endpoint is the duration of grade 3/4 neutropenia in chemotherapy cycle 1. As of August 1, 2014, 232 patients have completed chemotherapy cycle 1; safety and efficacy were analyzed for these enrolled patients. For the TC chemotherapy regimen, a total of 141 patients were randomized (ratio = 1:1:1:1) into 4 arms (80, 240, and 320 µg/kg benefilgrastim or 6 mg pegfilgrastim). In the TAC chemotherapy regimen, a total of 91 patients were randomized (ratio = 1:1:1) into 3 arms (240 and 320 µg/kg benefilgrastim or 6 mg pegfilgrastim). The incidence of grade 3/4 and grade 4 neutropenia and their mean durations in cycle 1 are provided in Table 1. There were higher incidences of grade 3/4 and grade 4 neutropenia in the TAC regimen compared to the TC regimen. The safety profiles of benefilgrastim and pegfilgrastim were similar. A total of 10 SAEs were reported in 6 patients with the majority (7 SAEs in 4 patients) occurring in those receiving pegfilgrastim. The most commonly observed treatment emergent adverse events (>10% of total TC + TAC patients) were: alopecia, nausea, asthenia, neutropenia, bone pain, and fatigue. The rates were similar amongst treatment regimens and treatment groups. In summary, a single subcutaneous injection of benefilgrastim 240 or 320 µg/kg provided neutrophil support to patients treated with both the TC and TAC chemotherapy regimens. The safety profile of benefilgrastim was comparable to that of pegfilgrastim during multiple chemotherapy cycles. The results suggest a potential use of benefilgrastim for the management of severe neutropenia in cancer patients undergoing high dose chemotherapy. Abstract 1584.

To further improve the effect of high-dose chemotherapy in the treatment of locally advanced and metastatic breast cancer, we sought to develop a second active high-dose noncross-resistant regimen to use in tandem with our customary high-dose regimen of cyclophosphamide, etoposide, and cisplatin (CVP). We performed a phase II trial of high-dose mitoxantrone 30 mg/m2, etoposide 200 mg/m2 every 12 hours x 6, and thiotepa 250 mg/m2 x 3 days (MVT) in 31 patients with heavily pretreated metastatic breast cancer and one with locally advanced chemotherapy-refractory breast cancer. These patients were ineligible for high-dose CVP chemotherapy because of the amount of prior treatment and poor-response status. Of the 32 patients, 14 responded to cycle 1, did not experience any grade 4 toxicity, and received a second cycle of MVT. Overall, seven of 31 patients achieved a complete response (CR; 23%). Four of the 14, who were partial responders to the first cycle, achieved a CR after the second cycle. The overall response rate was 19 of 31 (61%) with an overall median freedom from progression of 4 to 5 months and an overall median survival of 9 months. Toxicity consisted primarily of mucositis (grade 3 or 4 in 69%). The results indicate that high-dose MVT produces significant activity, even in heavily pretreated patients. Administration of a second cycle of high-dose therapy with MVT increased the CR rate, and the morbidity and mortality from the second cycle were not greater than that for the first cycle. Because of the high incidence of grade 3 or 4 mucositis with this regimen, we are currently completing a follow-up study of high-dose mitoxantrone and thiotepa alone.

Abstract Background - Chemotherapy-induced neutropenia (CIN) is the primary dose-limiting toxicity in patients receiving myelotoxic chemotherapy which is associated with increased morbidity and early mortality. Ryzneuta TM (F-627), a recombinant fusion protein containing human granulocyte-colony stimulating factor (G-CSF) and IgG2-Fc fragment, is intended to reduce CIN by utilizing the neutrophilic proliferating and activating properties of G-CSF. F-627 was designed as a novel, non-pegylated molecule with dimeric G-CSF, which may possess stronger G-CSF receptor activating properties and improved efficacy compared to filgrastim and pegfilgrastim. The primary objective of this study was to evaluate the safety and efficacy of F-627 given as a single fixed dose (20 mg) pre-filled syringe (PFS) as compared to Neulasta® (6 mg) in the first chemotherapy cycle. Methods - This was a phase III, multi-center, randomized, open-label, two-arm, active-controlled study that randomized female patients with Stage I to III invasive breast cancer who received 4 cycles of myelotoxic taxane + cyclophosphamide chemotherapy treatment. Forty-one (41) sites across 5 countries participated in the trial, including Bulgaria, Hungary, Russia, Ukraine, and US. Patients were randomized to F-627 or Neulasta® in a 1:1 ratio on the day of chemotherapy and administered study drug 24 hours after chemotherapy administration in each cycle. A total of 393 patients were randomized and analyzed for efficacy and safety. Clinical assessments were cycle-specific and included physical examination, serum samples for immunogenicity before each chemotherapy cycle, laboratory assessments, hematology and CBC with differentials, urinalysis, body weight, vital signs, adverse event (AE) collection, and concomitant medications. The pharmacokinetics (PK) and the pharmacodynamics (PD) of F-627 were also assessed. The primary efficacy endpoint was the duration in days of Grade 4 (severe) neutropenia (ANC <0.5 × 10 9/L) during cycle 1 of chemotherapy. Results - The mean duration of Grade 4 neutropenia in chemotherapy cycle 1 was 0.2 days for both F-627 and Neulasta®. F-627 was non-inferior compared to Neulasta® for the duration of Grade 4 neutropenia in chemotherapy cycle 1 with a mean difference of 0.0 days (95% CI: -0.1, 0.1), utilizing a non-inferiority margin of 0.6 days. The incidence of Grade 4 neutropenia in chemotherapy cycle 1 was comparable between F-627 and Neulasta®, 11.7% for both treatment groups. For chemotherapy cycles 2, 3, and 4, the incidence and duration of Grade 4 neutropenia was generally lower than in chemotherapy cycle 1. The mean durations of Grade 4 neutropenia were 0.1, 0.0, and 0.0 days for F-627 and 0.1, 0.1, and 0.1 days for Neulasta® in chemotherapy cycles 2,3,4, respectively. The incidence of Grade 4 neutropenia was 4.6%, 2.6%, and 1.6% for F-627 and 5.1%, 6.3%, and 5.3% for Neulasta® in chemotherapy cycles 2, 3, and 4, respectively. Across all chemotherapy cycles and for each chemotherapy cycle, the mean duration and the incidence of IV antibiotic use and hospitalization due to febrile neutropenia or any infection were low and comparable between F-627 and Neulasta®. The depth of ANC nadir was comparable in each chemotherapy cycle between F-627 and Neulasta®. For each chemotherapy cycle, time to ANC nadir was slightly longer for patients treated with F-627 than those with Neulasta®; the mean time to ANC nadir was 6.4, 6.1, 6.2, and 6.2 days for F-627, compared to 6.1,5.3, 5.7, and 5.5 days for Neulasta® in cycles 1, 2, 3, and 4, respectively. F-627 was well tolerated, with a low incidence of serious AEs and AEs leading to discontinuation, comparable to the profile for Neulasta®. There were 3 deaths during the study (1 for F-627 and 2 for Neulasta®). None of the deaths were related to study drug treatment. Clinical laboratory abnormalities were observed to be similar between the two treatment groups. Conclusion - Once-per-cycle F-627, given as a fixed 20 mg dose, was non-inferior to Neulasta® in reducing the duration of severe neutropenia following TC chemotherapy. F-627 was well tolerated during the study with an overall safety profile comparable to that for Neulasta®. F-627 is a safe, effective, and easy to use alternative to current CIN therapy.

PURPOSE: We evaluated the safety and efficacy of weekly paclitaxel therapy in women with metastatic breast cancer in a phase II multicenter trial. Entry criteria were relatively liberal to reflect the heterogeneity of metastatic breast cancer in clinical practice. PATIENTS AND METHODS: Patients had histologically confirmed and measurable metastatic breast cancer. Up to two prior chemotherapy regimens for metastatic disease, including prior therapy with anthracyclines and taxanes and prior high-dose therapy, were allowed. Paclitaxel 80 mg/m2 was administered weekly for 4 weeks per 4-week cycle. RESULTS: We enrolled 212 patients; 211 were assessable for toxicity and 177 were assessable for response. Ninety percent of patients had received prior chemotherapy (adjuvant, metastatic, or both), 46% of patients had three or more involved metastatic sites, and 60% of patients had visceral-dominant disease. Responses were documented on two occasions and were independently reviewed. The overall response rate (complete plus partial response) was 21.5% (95% confidence interval, 15.4% to 27.5%), with 41.8% of patients having disease stabilization. Median time to progression was 4.7 months, and overall survival in all 212 patients enrolled was 12.8 months. Therapy was well tolerated, with a 15% incidence of grade 3/4 hematologic toxicity and a 9% incidence of grade 3 neurotoxicity; other serious toxicities were rare. The response rate and toxicity profile in the 34% of patients ≥ 65 years of age were similar to that of younger patients. CONCLUSION: Weekly paclitaxel therapy was well tolerated and demonstrated reasonable activity in this relatively heavily pretreated population with advanced disease. Further study of weekly paclitaxel in combination therapy is warranted.

57 Background: FOLFOXIRI plus bevacizumab (BEV) is regarded as the standard of care for selected patients (pts) with metastatic colorectal cancer (mCRC), despite the high incidence of neutropenia and diarrhea. The AXEPT phase III study showed that the modified capecitabine (CAP) + irinotecan (IRI) + BEV (CAPIRI+BEV) [CAP 1600 mg/m2, IRI 200 mg/m2, and BEV 7.5 mg/kg q3wk] treatment was non-inferior to FOLFIRI+BEV, with a lower incidence of hematologic toxicity. We hypothesized that the modified CAPIRI combined with oxaliplatin (OX) and BEV (CAPOXIRI+BEV) would be more feasible than FOLFOXIRI+BEV, without compromising efficacy. Methods: The QUATTRO-II study is an open-label, multicenter, randomized phase II study. In Step 1, the recommended doses (RD) of OX and IRI were investigated as a safety lead-in. In Step 2, pts are randomized to either the RD of CAPOXIRI+BEV or FOLFOXIRI+BEV. In Step 1, four dose levels of CAPOXIRI (fixed dose of CAP 1600 mg/m2 and BEV 7.5 mg/kg plus escalated or de-escalated doses of OX and IRI, q3wk) were investigated in a 3+3 manner. A dose level of ≤ 2/6 of dose-limiting toxicity (DLT) cases was expected as the RD. Results: A total of 9 pts (3 at Level 0, 6 at Level 1) were included in Step 1. The baseline characteristics were as follows: the median age was 62 years; 6 were male; 6 presented with a left-sided tumor; 8 had a performance status of 0; all wild type/ RAS mutant/ BRAF V600E mutant were 8/1/0; and UGT1A1 wild type/*6 single hetero/*28 single hetero were 7/0/2. In Level 0 (IRI 200 mg/m2, OX 100 mg/m2), one grade 4 neutropenia and one grade 3 anorexia were observed, but without DLT. In Level 1 (IRI 200 mg/m2, OX 130 mg/m2), two grade 4 neutropenia and one grade 3 colitis were observed, with 1 DLT (febrile neutropenia) case, fully recovered without G-CSF administration. No treatment-related deaths were observed. Although dose modifications were needed in 4 of the 6 pts, no further safety concerns related to treatment continuity were observed in the 2nd or subsequent cycles. Thus, we determined that the dose administered in Level 1 is the RD for Step 2. According to the preliminary efficacy results at 8 weeks after initiating study treatment, 6 pts achieved a partial response (2 in Level 0 and 4 in Level 1). Conclusions: The RD of CAPOXIRI+BEV was 200 mg/m2 IRI, 130 mg/m2 OX, 1600 mg/m2 CAP, and 7.5mg/kg BEV. The randomized phase II Step (Step 2) of QUATTRO-II is ongoing. Clinical trial information: NCT04097444.

Background Currently, the recommended dose of nivolumab for patients with relapsed or refractory classical Hodgkin lymphoma (r/r сHL) is 3 mg/kg. Nevertheless, published clinical cases indicate the possible efficacy of lower doses of nivolumab. Moreover, experimental studies provided the rationale for possible reduction of nivolumab dose in patients with solid tumors (Agrawal et al. 2016). The presented data creates prerequisites for studying the lower nivolumab doses efficacy and safety in the r/r cHL therapy. Patients and Methods This study included 42 patients (14 male/28 female) with r/r cHL who were treated with nivolumab 40 mg every 2 weeks. The median age of patients was 36 (22-53) years. The median number of prior therapy lines was 4 (2-7). Prior treatment contained high dose chemotherapy with ASCT in 9 pts (21%), brentuximab vedotin in 14 pts (33%) and allo-HSCT in 1 pt (2%). Four pts (9,5%) had the partial response (PR) and the remaining 38 pts (90,5%) had the disease progression (PD) at the moment of nivolumab initiation. B-symptoms were present in 23 pts (55%), ECOG status was grade 0-I in 25 pts (59,5%), grade II in 12 pts (29%), grade III in 4 pts (9,5%) and grade IV in 1 pt (2%). The primary endpoint was the overall response rate (ORR) determined by positron-emission tomography/computed tomography (PET/CT) using LYRIC criteria every 3 months. Key secondary endpoints included progression-free survival (PFS) and overall survival (OS). Adverse events (AE) were evaluated according to CTCAE 4.03. The patient group characteristics were evaluated using descriptive statistics methods, the survival analysis was performed using Kaplan-Meyer method (SPSS Statistics v.17). Results The median number of nivolumab cycles was 24 (2-38). The response was evaluated in 41 out of 42 pts. The ORR was 66%. The best response included complete response (CR) in 39%, PR in 27%, stable disease in 5%, PD in 2%, indeterminate response (IR) in 27% of pts. With a median follow-up of 27,5 mo (11,3-34,5) 41 pts (97,6%) were alive, the median OS was not reached. The 2-year PFS was 44,5% (95% CI, 28,2-59,6) The nivolumab therapy was discontinued in 39 pts (93%) due to scheduled discontinuation in 14 pts (33%), PD in 13 pts (31%), grade 3-4 AE in 2 pts (5%), change of therapy because of insufficient response in 6 pts (14%) and other reasons in 4 pts (10%). The progression of disease during nivolumab therapy was present in 14 (33%) pts and after nivolumab discontinuation in 6 (14%) pts. After disease progression 30 pts (71%) were retreated with nivolumab monotherapy or in combination with chemotherapy. The median time to additional therapy was 14,5 mo (4,2 -32,9). The adverse events of any severity were observed in 30 pts (71%). Grade 3 or higher AE were present in 4 pts (9,5%), including grade 3 arthralgia, grade 3 anemia, grade 4 pneumonia and pneumonitis, grade 4 increased level of alanine aminotransferase and grade 5 MDS in 1 pt. A significant reduction of PD1+CD3+ cell population of peripheral blood lymphocytes was observed after first nivolumab cycle (median 0.7% (0-1.7) versus 33% (15.7-80.1) before therapy initiation, p = 0.02, Wilcoxon signed-rank test). Conclusion Our study demonstrated the efficacy and safety of nivolumab 40 mg therapy. The presented results are comparable to previously published data of nivolumab 3 mg/kg therapy in patients with r/r cHL. Thus, this creates a basis for further direct comparative study of nivolumab efficacy in different doses Disclosures No relevant conflicts of interest to declare.

PURPOSE: To study tolerability and efficacy of an intensified chronomodulated schedule of fluorouracil (5-FU) and l-folinic acid (l-FA) as first-line treatment of metastatic colorectal cancer, 5-FU was given near individually determined dose-limiting toxicity in a multicenter phase II trial. PATIENTS AND METHODS: One hundred patients (68 men and 32 women, median age 62 years, World Health Organization performance status ≤ 2) with previously untreated and inoperable metastases received chronomodulated daily infusion of 5-FU/l-FA (from 10:00 pm to 10:00 am with peak at 4:00 am). 5-FU dose was escalated from 900 to 1,100 mg/m2/d with fixed dose of l-FA at 150 mg/m2/d for 4 days every 14 days. RESULTS: 5-FU dose escalation was achieved in 66% of the patients. Grade 3 to 4 toxicities mainly consisted of nausea or vomiting (14% of patients and 1.5% of courses), hand-foot syndrome (38% of patients and 8% of courses), mucositis (26% of patients and 4% of courses), and diarrhea (21% of patients and 2.3% of courses). Objective response rate (ORR) was 41% (95% confidence interval, 31.5% to 50.5%). Twenty patients underwent metastases surgery; among these, 12 had a complete resection. Median progression-free survival was 7 months. Median survival was 17 months; 28% of the patients were alive at 2 years and 18.6% at 3 years. CONCLUSION: The ORR achieved with intensified chronomodulated delivery of 5-FU/l-FA was nearly twice as high as that earlier obtained by our cooperative group using less intensive 5-FU/FA chronotherapy.
