Filter by:Background: The prognosis of pts who have failed multiple chemotherapy (CT) regimens is quite dismal. PD-L1 is frequently expressed by immunohistochemistry (IHC) in germ cell tumors (GCT). D is a monoclonal antibody (mAb) that inhibits the binding of PD-L1. T, an anti-CTLA4 mAb, is an immunomodulatory therapy. Combination immunotherapy has shown improved activity compared to monotherapy. The investigators aimed to investigate the activity of D, alone or in combination with T, in chemorefractory GCT. Trial Design: This is an open-label, randomized, 3-stage, phase 2 study. Pts who have failed ≥2 prior CT regimens (including high-dose CT) will be randomized to receive one of the following: D, 1.5 g via IV infusion q4w, for up to a total of 12 months (13 doses/cycles) alone or with T, 75 mg IV q4w, starting on week 0, for up to 4 months (4 doses/cycles). Serum tumor markers, computed tomography and fluorodeoxyglucose positron emission tomography (FDG-PET) scans will be repeated q8 weeks. The primary endpoint is the objective response-rate (ORR=complete response or partial response with normal markers). H0: ORR rate ≤10%, H1: ORR ≥25%, type I and II error rates at 10%. In stage 1, 11 pts will be allocated in each arm. According to Gehan's rule, the trial will be terminated whenever no response will be observed. 29 additional pts will be added to each arm fulfilling stage 1 criteria. ORR in ≥7 pts will be required. In stage 3, pts from stage 1-2 of both arms will be retrospectively evaluated for Programmed cell Death Ligand-1(PD-L1) IHC. The Ventana PD-L1 IHC assay will be used. In case of negative findings at the end of stage 2, if the target benefit is likely to occur only in PD-L1+ pts, further study prosecution in accordance with an enrichment strategy will be undertaken. In particular, predictive power (PP) will be calculated assuming expansion of PD-L1+ cohorts up to a maximum of 60 pts. Each arm will be categorized as not promising (PP<30%) or promising (PP ≥30%). The promising one will enter the stage 3. Should both arms be judged promising, the one yielding ≥20% PP advantage will be selected; monotherapy will be preferred otherwise. Details on the algorithm to be used for PD-L1 IHC in this study will be finalized (EudraCT number 2016-001688-35).
This is a multi-center phase II study of brentuximab vedotin in combination with bevacizumab for the treatment of refractory CD-30+ germ cell tumors (GCT) after disease progression on imaging and/or tumor marker progression documented by serially rising alpha-fetoprotein (AFP) or beta human chorionic gonadotropin (bHCG) measured on at least 2 consecutive visits and determined by treating physician to be clinically significant. Patients unable to receive 2nd line of platinum-based chemotherapy due to toxicity or refusal would also be eligible.
Toxicities related to pediatric cancer treatment can lead to significant illness, organ damage, treatment delays, increased health care cost, and decrease in quality of life. Such toxicities are largely due to tissue damage sustained by chemotherapy, and strategies designed to limit such cellular damage to normal tissues may reduce therapy-related morbidity and mortality. In addition to their in vitro and in vivo anti-cancer effects, naturally occurring soy isoflavones have anti-inflammatory and anti-oxidant properties, and have been shown to reduce side effects of therapy in adult oncology clinical trials. This study will examine the effect of genistein, the major isoflavone component in soybeans and the most extensively studied of the soy isoflavones, on short-term side effects of myelosuppressive chemotherapy in pediatric cancer patients. Subjects will be randomized to receive either: a) 30 mg genistein daily throughout chemotherapy Cycles 1 and 2 and placebo during chemotherapy Cycles 3 and 4; or b) placebo daily during chemotherapy Cycles 1 and 2 and 30 mg genistein daily during chemotherapy Cycles 3 and 4. Investigators hypothesize that subjects will have fewer short-term therapy-related side effects during cycles of chemotherapy given in conjunction with genistein supplementation than cycles given with placebo.
RATIONALE: Giving CpG 7909 after an autologous stem cell transplant may make a stronger immune response and prevent or delay the recurrence of cancer. PURPOSE: This phase I trial is studying the side effects and best dose of CpG 7909 in treating patients who have undergone autologous stem cell transplant.
This study proposes to evaluate the combination of cisplatin plus epirubicin in patients with refractory germ cell tumor not amendable to cure with surgery or standard platinum salvage chemotherapy. This regimen will be used in eligible patients after progression on ECOG Study E39897.
