ABSTRACT: Combining targeted treatments for renal cell carcinoma has been suggested as a possible method to improve treatment efficacy. We aimed to assess the potential synergistic or additive effect of the combination of bevacizumab, directed against the VEGF receptor, and temsirolimus, an mTOR inhibitor, in metastatic renal cell carcinoma.
TORAVA was an open-label, multicentre randomised phase 2 study undertaken in 24 centres in France. Patients aged 18 years or older who had untreated metastatic renal cell carcinoma were randomly assigned (2:1:1) to receive the combination of bevacizumab (10 mg/kg every 2 weeks) and temsirolimus (25 mg weekly; group A), or one of the standard treatments: sunitinib (50 mg/day for 4 weeks followed by 2 weeks off; group B), or the combination of interferon alfa (9 mIU three times per week) and bevacizumab (10 mg/kg every 2 weeks; group C). Randomisation was done centrally and independently from other study procedures with computer-generated permuted blocks of four and eight patients stratified by participating centre and Eastern Cooperative Oncology Group performance status. The primary endpoint was progression-free survival (PFS) at 48 weeks (four follow-up CT scans), which was expected to be above 50% in group A. Analysis was by intention to treat. The study is ongoing for long-term overall survival. This study is registered with ClinicalTrials.gov, number NCT00619268.
Between March 3, 2008 and May 6, 2009, 171 patients were randomly assigned: 88 to the experimental group (group A), 42 to group B, and 41 to group C. PFS at 48 weeks was 29.5% (26 of 88 patients, 95% CI 20.0-39.1) in group A, 35.7% (15 of 42, 21.2-50.2) in group B, and 61.0% (25 of 41, 46.0-75.9) in group C. Median PFS was 8.2 months (95% CI 7.0-9.6) in group A, 8.2 months (5.5-11.7) in group B, and 16.8 months (6.0-26.0) in group C. 45 (51%) of 88 patients in group A stopped treatment for reasons other than progression compared with five (12%) of 42 in group B and 15 (38%) of 40 in group C. Grade 3 or worse adverse events were reported in 68 (77%) of 88 patients in group A versus 25 (60%) of 42 in group B and 28 (70%) of 40 in group C. Serious adverse events were reported in 39 (44%) of 88, 13 (31%) of 42, and 18 (45%) of 40 patients in groups A, B, and C, respectively.
The toxicity of the temsirolimus and bevacizumab combination was much higher than anticipated and limited treatment continuation over time. Clinical activity was low compared with the benefit expected from sequential use of each targeted therapy. This combination cannot be recommended for first-line treatment in patients with metastatic renal cell carcinoma.

ABSTRACT: Two chemotherapy regimens for intermediate- and poor-risk metastatic nonseminomatous germ cell tumors were compared for efficacy and toxicity.
From February 1994 to February 2000, 190 patients were randomly assigned between either four cycles of BEP (bleomycin 30 mg d1, d8, d15; etoposide 100 mg/m(2) d1-5; cisplatin 20 mg/m(2) d1-5) or four to six alternating cycles of CISCA/VB (cyclophosphamide 400 mg/m(2) d1-2, doxorubicin 35 mg/m(2) d1-2, cisplatin 100 mg/m(2) d3/vinblastine 2.5 mg/m(2) d1-5, bleomycin 25 mg/m(2) d1-5). Risk was initially defined according to the Institut Gustave Roussy (Villejuif, France) prognostic model based on serum alpha-fetoprotein and human chorionic gonadotropin levels only. Patients were retrospectively assigned into the International Germ Cell Consensus Classification.
Among 185 assessable patients, favorable responses did not differ statistically between the two arms: 49 in the CISCA/VB arm (56%; 95% CI, 45% to 66%), 57 in the BEP arm (65%; 95% CI, 55% to 75%). The CISCA/VB regimen induced more significant hematologic and mucous toxicities compared with the BEP arm. The 5-year event-free survival rates were 37% (95% CI, 27% to 47%) and 47% (95% CI, 37% to 57%) in CISCA/VB and BEP arms, respectively (hazard ratio [HR] = 0.76; 95% CI, 0.52 to 1.11; P = .15). With a median follow-up of 7.8 years, the 5-year overall survival rates were 59% (95% CI, 47% to 67%) and 69% (95% CI, 58% to 77%) in CISCA/VB and BEP arms, respectively (HR = 0.73; 95% CI, 0.46 to 1.18; P = .24).
Because of equivalent efficacy and lesser toxicity, the standard treatment for patients with intermediate- and poor-risk metastatic nonseminomatous germ cell tumors remains four cycles of BEP.

ABSTRACT: The aim of this phase II study was to evaluate safety and efficacy of an oxaliplatin/vinorelbine/5-fluorouracil (FON) combination in anthracycline and taxane-pretreated metastatic breast cancer patients. The following treatment was given: on day 1 of a 21-day cycle, oxaliplatin 130 mg/m (2-h intravenous infusion); on days 1 and 5, vinorelbine [dose level (DL) 1: 17.5 mg/m; DL2: 22 mg/m]; on days 1-5, continuous infusion 5-fluorouracil (DL1: 600 mg/m/day; DL2: 750 mg/m/day). Forty-seven patients were treated (DL1: 43; DL2: 4). Median age was 54 years; 68% had liver metastases, 53% were taxane refractory/resistant and 38% were anthracycline refractory/resistant. Patients received a median of six treatment cycles. Of 46 eligible patients, 16 had partial response; the overall response rate was 34.8% (95% confidence interval 21.3-50.3%), 11 had stable disease lasting more than 4 months. Median follow-up was 13.0 months, median time to progression 5.7 months and estimated overall survival 18.8 months. DL2 was too toxic with three patients having grade 3-4 toxicity, including one death. At DL1, 26 patients (60%) experienced grade 3-4 neutropenia (six febrile neutropenia) and eight had grade 3 oxaliplatin-specific peripheral neuropathy after a median of 646.4 mg/m oxaliplatin (range 124-1619 mg/m). Oxaliplatin (130 mg/m, day 1)/vinorelbine (17.5 mg/m, days 1,5)/5-fluorouracil (600 mg/m/day, days 1-5) demonstrate encouraging activity and a manageable safety profile in anthracycline- and taxane-pretreated metastatic breast cancer patients.

ABSTRACT: The main objective of this trial was to evaluate the combination of subcutaneous (SC) interleukin-2 (IL-2) with interferon alpha-2a (IFN-alpha) in the treatment of patients with metastatic renal cell carcinoma (MRCC) compared with a previous trial that used continuous-infusion IL-2 and IFN-alpha with identical schedules and dosages.
Between April, 1997 and January, 1998, 66 patients with MRCC received SC IL-2 at a dose of 9 x 10(6) IU/m(2) twice daily for 5 days during 2 induction cycles and during 4 additional cycles, with a 3-week rest between cycles. Each induction cycle consisted of two 5-day courses of IL-2 separated by a 9-day break. IFN-alpha at a dose of 6 x 10(6) IU per day three times per week was given during induction cycles and additional cycles.
All patients were assessable for response and toxicity. The median follow-up was 43 months. Thirty-five patients (51%) and 43 patients (63%) received >or= 80% of the planned induction doses of IL-2 and IFN-alpha, respectively. Five patients achieved objective responses (7.6%; 95% confidence interval [95%CI], 2.5-16.8%), with two complete responses. The median survival was 14 months (95%CI, 11.3-16.7 months). Fifty-three patients (80%) had at least one episode of Grade 3 toxicity related to treatment. Twenty-two patients developed Grade 4 toxicities, which included hypotension (24% of patients), decreased performance status (6% of patients), dyspnea (3% of patients), and mucositis (3% patients) as well as fever, ventricular tachycardia, and anemia.
The current results seem to indicate reduced efficacy and higher toxicity rates with SC IL-2 plus IFN-alpha compared with the results from a previous trial that used an identical regimen with IV IL-2 administration. Although SC IL-2 regimens are used widely, their interest remains to be determined.
