In the past 5 years, treatment for metastatic Renal Cell Carcinoma (mRCC) has focused on agents directed at blocking tumor and vascular growth pathways. Sunitinib blocks the vascular endothelial growth factor receptor (VEGFr) and temsirolimus is an inhibitor of mammalian target of rapamycin (mTOR). Both sunitinib and temsirolimus are FDA approved agents for mRCC. When agents like these are given together, the toxicity increases but they can be given safely, at full doses, sequentially. We hypothesize that alternating these agents will double the progression free survival (PFS) of the agents when given sequentially.
This trial was originally designed and powered to compare biomarker modulation in the neo-adjuvant setting (erlotinib versus erlotinib plus sulindac versus placebo) with clinical response to erlotinib in the adjuvant setting. Since implementing the trial in late 2005, The investigators have encountered significant obstacles to implementing the adjuvant therapy phase of the trial. - Barriers included: 1. disease recurrence 2. patient refusal to take the agent 3. patient refusal to travel to Pittsburgh for clinical evaluations. Given the institutional challenges to implement and complete the adjuvant portion, the investigators have decided to change the primary endpoint to a biomarker modulation endpoint. To achieve this goal, the investigators determined that they needed 39 paired tissue specimens (see statistical justification below). The central hypothesis to be tested in this study is that persistent activation of parallel and/or downstream pathways contributes to tumor progression in the setting of EGFR blockade. While not all head and neck squamous cell carcinoma (HNSCC) patients will respond to EGFR targeting, the optimal strategy to identify those subjects whose tumors are sensitive to EGFR inhibition remains unknown. The primary objective is centered around the concept of tumor biomarkers which may be modulated by EGFR and Cox-2 inhibitors and may serve as future therapeutic targets for therapy. To this end patients on this trial will be randomly assigned to one of three arms to receive either Tarceva, Tarceva plus sulindac, or a placebo in the 2 week pre-operative period. A panel of biomarkers will be obtained by biopsy prior to pre-operative therapy and again at surgery. Biomarkers will be examined for modulation in the 2-week pre-operative period, for group differences, for treatment effects and for further understanding of protein signaling pathways. Sample size for the primary objective Modification of Statistical Design: The primary endpoint is the difference between pre (biopsy) and post (surgery). There are 3 hypotheses of interest: (1) placebo vs erlotinib alone, (2) placebo versus erlotinib plus sulindac, and (3) erlotinib vs erlotinib + sulindac. With a randomization in a 3:5:5 ratio, we have 88% power, alpha = .01 for an omnibus test to show between-group differences of 1 log exist. This requires 39 patients. Basically, 39 patients will provide the ability to detect a one log difference between any 2 of the 3 groups in pre-post change.
- Design: non-randomized, open label, phase II clinical trial. - Study population and disease: adult patients with metastatic or locally advanced non-resectable adrenocortical carcinoma, confirmed histologically. - Estimated number of patients: 15. - Study drug: dovitinib (TKI-258), dosed on a flat scale of 500mg/day on a 5 days on / 2 days off. - Treatment duration: study treatment period will be continued until disease progression, unacceptable toxicity, death or premature withdrawal from study. An average of 6 months treatment period is expected. - Study duration: expected recruitment period will be 18 months, and patients will be followed for 6 additional months after last patient is included in the trial.Study total expected duration is 24 months. - Sites: the study is planned to be conducted in 7 Spanish centers.
Patients with metastatic renal cell carcinoma (mRCC) who failed first-line therapy with sunitinib or pazopanib was treated with everolimus. Efficacy and safety of everolimus was evaluated in these patients.
Phase I / II, open, prospective, multicenter single-arm, Clinical Trial in two stages: in the first stage it will determine the optimal dose of the combination of pazopanib and interferon alfa-A2 in the treatment of patients with advanced renal carcinoma and a second stage that will determine the efficacy of this combination measured in terms of response rate.
We hypothesise that the use of transarterial chemoembolisation (TACE) after liver resection in patients with hepatocellular carcinoma can eradicate residual cancer cells in the liver and thus improve survival. The aim of this study is to compare the survival of patients undergoing liver resection plus post-operative TACE versus liver resection alone.
This is an open labeled phase I dose escalation study of hydroxychloroquine (HCQ) and RAD001 in patients with advanced renal cell carcinoma followed by a Phase II trial of RAD001 with HCQ. The target population are patients with one to three prior treatments for advanced renal cell carcinoma. In the phase I portion a traditional 3+3 design will be used to determine the maximal tolerated dose and/or recommended phase II dose for HCQ in combination with RAD001 po 10 mg/day.
The purpose of this study is to determine whether prophylactic central neck dissection is beneficial for patients with papillary thyroid cancer staged preoperatively as node negative.
This is an observational study which will investigate the use of Nexavar as first targeted therapy in patients with advanced renal cell carcinoma.
