Safety and Efficacy of Nivolumab Monotherapy in Recurrent or Metastatic Cervical, Vaginal, or Vulvar Carcinoma: Results From the Phase I/II CheckMate 358 Trial

Purpose: Nivolumab was assessed in patients with virus-associated tumors in the phase I/II CheckMate 358 trial (ClinicalTrials.gov identifier: NCT02488759). We report on patients with recurrent/metastatic cervical, vaginal, or vulvar cancers. Patients and methods: Patients received nivolumab 240 mg every 2 weeks. Although patients with unknown human papillomavirus status were enrolled, patients known to have human papillomavirus-negative tumors were ineligible. The primary end point was objective response rate. Duration of response (DOR), progression-free survival, and overall survival were secondary end points. Safety and patient-reported outcomes were exploratory end points. Results: Twenty-four patients (cervical, n = 19; vaginal/vulvar, n = 5) were enrolled. Most patients had received prior systemic therapy for metastatic disease (cervical, 78.9%; vaginal/vulvar, 80.0%). Objective response rates were 26.3% (95% CI, 9.1 to 51.2) for cervical cancer and 20.0% (95% CI, 0.5 to 71.6) for vaginal/vulvar cancers. At a median follow-up of 19.2 months, median DOR was not reached (range, 23.3 to 29.5+ months; + indicates a censored observation) in the five responding patients in the cervical cohort; the DOR was 5.0 months in the single responding patient in the vaginal/vulvar cohort. Median overall survival was 21.9 months (95% CI, 15.1 months to not reached) among patients with cervical cancer. Any-grade treatment-related adverse events were reported in 12 of 19 patients (63.2%) in the cervical cohort and all five patients in the vaginal/vulvar cohort; there were no treatment-related deaths. In the cervical cohort, nivolumab treatment generally resulted in stabilization of patient-reported outcomes associated with health status and health-related quality of life. Conclusion: The efficacy of nivolumab in patients with recurrent/metastatic cervical and vaginal or vulvar cancers is promising and warrants additional investigation. No new safety signals were identified with nivolumab treatment in this population

Incidence of reversible amenorrhea in women with breast cancer undergoing adjuvant anthracycline-based chemotherapy with or without docetaxel

<p>Abstract</p> <p>Background</p> <p>To determine the incidence of reversible amenorrhea in women with breast cancer undergoing adjuvant anthracycline-based chemotherapy with or without docetaxel.</p> <p>Methods</p> <p>We studied the incidence and duration of amenorrhea induced by two chemotherapy regimens: (i) 6 cycles of 5-fluorouracil 500 mg/m², epirubicin 100 mg/m²and cyclophosphamide 500 mg/m²on day 1 every 3 weeks (6FEC) and (ii) 3 cycles of FEC 100 followed by 3 cycles of docetaxel 100 mg/m²on day 1 every 3 weeks (3FEC/3D). Reversible amenorrhea was defined as recovery of regular menses and, where available (101 patients), premenopausal hormone values (luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol) in the year following the end of chemotherapy.</p> <p>Results</p> <p>One hundred and fifty-four premenopausal patients were included: 84 treated with 6FEC and 70 with 3FEC/3D. The median age was 43.5 years (range: 28–58) in the 6FEC arm and 44 years (range: 29–53) in the 3FEC/3D arm. Seventy-eight percent of patients were treated in the context of the PACS 01 trial. The incidence of chemotherapy-induced amenorrhea at the end of chemotherapy was similar in the two groups: 93 % in the 6FEC arm and 92.8 % in the 3FEC/3D arm. However, in the year following the end of chemotherapy, more patients recovered menses in the 3FEC/3D arm than in the 6FEC arm: 35.5 % versus 23.7 % (p = 0.019). Among the 101 patients for whom hormone values were available, 43 % in the 3FEC/3D arm and 29 % in the 6FEC arm showed premenopausal levels one year after the end of chemotherapy (p < 0.01). In the 3FEC/3D group, there was a statistically significant advantage in disease-free survival (DFS) for patients who were still amenorrheic after one year, compared to patients who had recovered regular menses (p = 0.0017).</p> <p>Conclusion</p> <p>Our study suggests that 3FEC/3D treatment induces more reversible amenorrhea than 6FEC. The clinical relevance of these findings needs to be investigated further.</p

Systemic treatment for locally advanced breast cancer: what we still need to learn after a decade of multimodality clinical trials.

Multimodality therapy of locally advanced breast cancer with initial chemo-(hormono)-therapy followed by locoregional treatment has become increasingly popular during the past decade. A paucity of large randomised clinical trials leaves the following unanswered questions: does systemic treatment impact on long-term control of distant metastases? What is the best treatment sequence? The most effective drug combination? The optimum treatment duration? Future prospects in the treatment of locally advanced breast cancer include the use of haematopoietic growth factors to increase the dose-intensity of neoadjuvant chemotherapy, the investigation of autologous bone marrow transplantation with high dose chemotherapy on a larger scale, the development of new approaches designed at interrupting the "autocrine loop" of breast cancer local growth factors and the introduction of diphosphonates in the adjuvant systemic therapy.Journal ArticleReviewinfo:eu-repo/semantics/publishe

Phase I clinical and pharmacokinetic study of zeniplatin, a new platinum complex.

Forty-six patients with refractory solid malignancies received the new platinum complex [2,2-bis(aminomethyl)-1,3-propanediol-N-N'] [1,1-cyclobutanedicarboxylato] [(2-)0,0')] platinum (zeniplatin). Zeniplatin was given, without hydration or mannitol, as a 60- to 90-min i.v. infusion every 3 weeks at doses ranging from 8 to 145 mg/m2. The maximum tolerated dose of zeniplatin was 145 mg/m2. The dose-limiting toxicity of zeniplatin was dose-related leukopenia and neutropenia, with the nadir usually observed between 1 and 2 weeks after therapy and recovery usually occurring by 3 weeks after therapy. Thrombocytopenia was rare. The most prominent non-hematological side-effect of zeniplatin was nausea and vomiting. Other non-hematological side-effects were mild or absent. Zeniplatin did not induce significant neurological or auditory toxicity. Zeniplatin was not nephrotoxic at doses less than or equal to 120 mg/m2. At 145 mg/m2, the clearance decreased by a mean of 40% after 2 cycles of therapy. Two patients, one with malignant melanoma and one with renal cell cancer, achieved a partial response. Pharmacokinetics of free (plasma ultrafiltrates) and total platinum in plasma were determined in 5 patients. An in vitro study of the rate and extent of zeniplatin binding to protein in human plasma was also performed. Free and total platinum were measured by flameless atomic absorption spectrometry; free zeniplatin was measured in ultrafiltrate by HPLC. Total and free plasma platinum concentrations were co-modelled using the information from the in vitro study.(ABSTRACT TRUNCATED AT 250 WORDS)Clinical TrialControlled Clinical TrialJournal ArticleResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe

Cetuximab, docetaxel, and cisplatin as first-line treatment in patients with recurrent or metastatic head and neck squamous cell carcinoma: a multicenter, phase II GORTEC study.

Cetuximab in combination with platinum and 5-fluorouracil is the standard of care in the first-line treatment of patients with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). Cetuximab and taxane combinations have shown promising activity. This study evaluated the efficacy and safety of four cycles of docetaxel associated with cisplatin and cetuximab (TPEx), followed by maintenance with cetuximab every 2 weeks. Patients with a histologically confirmed HNSCC with metastasis or recurrence unsuitable for locoregional curative treatment received docetaxel and cisplatin (75 mg/m(2) both) at day 1 and weekly cetuximab 250 mg/m(2) (loading dose of 400 mg/m(2)), repeated every 21 days for four cycles, followed by maintenance cetuximab 500 mg/m(2) every 2 weeks until progression or unacceptable toxicity. Prophylactic administration of granulocyte colony-stimulating factor was done systematically after each chemotherapy cycle. Patients had a good general status (performance status ≤1) and were under 71 years. Prior total doses of cisplatin exceeding 300 mg/m(2) were not allowed. The primary end point was objective response rate (ORR) after four cycles. Fifty-four patients were enrolled. The primary end point was met with an ORR of 44.4% (95% CI 30.9-58.6). Median overall and progression-free survivals were, respectively, 14 months (95% CI 11.3-17.3) and 6.2 months (95% CI 5.4-7.2). The most common grade 3/4 adverse events were skin rash (16.6%) and non-febrile neutropenia (20.4%). There were one pulmonary embolism and two infectious events leading to death. The TPEx regimen showed promising activity as first-line treatment in fit patients with recurrent/metastatic HNSCC. Further studies are needed to compare the TPEx versus EXTREME regimen in this population. NCT01289522
