Outcomes in Patients With Metastatic Renal Cell Carcinoma Who Develop Everolimus-Related Hyperglycemia and Hypercholesterolemia : Combined Subgroup Analyses of the RECORD-1 and REACT Trials

In this study we examined the outcome of metastatic renal cell cancer patients with everolimus treatment related hyperglycemia and hypercholesterolemia. All patients were treated in 2 large, international prospective trials, RECORD-1 (REnal Cell cancer treatment with Oral RADOO1 given Daily) and REACT (RADOO1 Expanded Access Clinical Trial in RCC). Patients who experienced these events might have experienced an improved response to everolimus. Background: Hyperglycemia and hypercholesterolemia are class effects of mammalian target of rapamycin inhibitors. The purpose of this study was to characterize safety and efficacy of patients with metastatic renal cell carcinoma (mRCC) treated with everolimus in RECORD-1 (REnal Cell cancer treatment with Oral RAD001 given Daily) and REACT (RAD001 Expanded Access Clinical Trial in RCC) who developed these events. Patients and Methods: Adults with vascular endothelial growth factor refractory mRCC received everolimus 10 mg/d in the randomized RECORD-1 (n = 277) and open-label REACT (n = 1367) studies. Outcomes included safety, treatment duration, overall response, and progression free survival for patients who developed hypercholesterolemia or hyperglycemia. Results: In RECORD-1, 12% (33 of 277) and 20% (55 of 277) of patients developed any grade hyperglycemia or hypercholesterolemia, respectively, with only 6% (78 of 1367) and 1% (14 of 1367) of the same events, respectively, in REACT. Median everolimus treatment duration was similar for patients with hyperglycemia or hypercholesterolemia (RECORD-1, 6.2 and 6.2 months, respectively; REACT, 4.4 and 4.5 months, respectively), but longer-than the overall populations (RECORD-1, 4.6 months; REACT, 3.2 months). In RECORD-1/REACT, 82%/68% of patients with hyperglycemia and 75%/71% of patients with hypercholesterolemia achieved partial response or stable disease. The incidence of clinically notable Grade 3 or 4 adverse events, other than anemia and lymphopenia, appeared to be similar across trials and subgroups. Although there was a trend for improved progression-free survival with development of hyperglycemia or hypercholesterolemia, the association was not statistically significant. Conclusion: Hyperglycemia and hypercholesterolemia were observed in low numbers of patients, and although these events might be associated with improved response to everolimus, the differences were not significant. These findings should be validated with prospective biomarker studies.Peer reviewe

Genome-wide linkage screen for testicular germ cell tumour susceptibility loci

A family history of disease is a strong risk factor for testicular germ cell tumour (TGCT). In order to identify the location of putative TGCT susceptibility gene(s) we conducted a linkage search in 237 pedigrees with two or more cases of TGCT. One hundred and seventy-nine pedigrees were evaluated genome-wide with an average inter-marker distance of 10 cM. An additional 58 pedigrees were used to more intensively investigate several genomic regions of interest. Genetic linkage analysis was performed with the ALLEGRO software using two model-based parametric analyses and a non-parametric analysis. Six genomic regions on chromosomes 2p23, 3p12, 3q26, 12p13-q21, 18q21-q23 and Xq27 showed heterogeneity LOD (HLOD) scores of greater than 1, with a maximum HLOD of 1.94 at 3q26. Genome-wide simulation studies indicate that the observed number of HLOD peaks greater than one does not differ significantly from that expected by chance. A TGCT locus at Xq27 has been previously reported. Of the 237 pedigrees examined in this study, 66 were previously unstudied at Xq27, no evidence for linkage to this region was observed in this new pedigree set. Overall, the results indicate that no single major locus can account for the majority of the familial aggregation of TGCT, and suggests that multiple susceptibility loci with weak effects contribute to the diseas

A Randomized, Double-Blind, Placebo-Controlled Phase II Study of Vandetanib Plus Docetaxel/Prednisolone in Patients with Hormone-Refractory Prostate Cancer

Vandetanib (ZACTIMA(TM)) is a once-daily oral anticancer drug that selectively inhibits vascular endothelial growth factor receptor, epidermal growth factor receptor, and rearranged during transfection signaling. This randomized (1: 1), double-blind study evaluated vandetanib (100mg/day) or placebo in combination with docetaxel (D; 75mg/m(2) every 3 weeks) and prednisolone (P; 2 x 5 mg/day) in 86 patients with metastatic hormone-refractory prostate cancer (mHRPC). The primary assessment was prostate-specific antigen (PSA) response (confirmed reduction of >= 50% from baseline) and a greater number of patients showed a PSA response with placebo + DP (67%) versus vandetanib + DP (40%); hazard ratio = 2.23 (one-sided 80% confidence limit = 2.90; one-sided p = 0.99). More patients experienced progression events (disease progression or death from any cause) with vandetanib + DP (65%) versus placebo + DP (60%); hazard ratio = 1.13 (one-sided 80% confidence limit = 1.44; one-sided p = 0.67). The overall incidence of adverse events was similar in both groups, although more patients experienced adverse events, leading to permanent discontinuation with vandetanib + DP (28%) versus placebo + DP (12%). However, the safety and tolerability profile for vandetanib was similar to that previously reported; adverse events that occurred more frequently in the vandetanib + DP arm were hypertension (14% vs. 2%), erythematous rash (14% vs. 2%), and exfoliative rash (12% vs. 2%). In this study of patients with mHRPC, vandetanib + DP did not demonstrate any efficacy benefit, compared with placebo + DP.AstraZenec

Prognostic factors for survival in the phase III TROPIC trial.

102 Background: In TROPIC ( NCT00417079 ) 755 men were randomized (378 cabazitaxel/prednisone [CbzP]; 377 mitoxantrone/prednisone [MP]). Treatment arms were well balanced; ECOG PS 0–1 (93% CbzP vs 91% MP), measurable disease (53% vs 54%), baseline pain (46% vs 45%) and ≤ 6 months from last dose of docetaxel (D) to randomization (62% vs 72%). CbzP significantly improved overall survival (OS) in mCRPC pts who progressed on or after D treatment compared with MP (HR 0.70; CI 0.59–0.83; P &lt; 0.0001). We investigated overall prognosis and performed a multivariate analysis of factors implicated in OS from this robust dataset. Methods: A univariate analysis of a variety of factors followed by a multivariate analysis of all factors was conducted. Interactions with treatment arms were explored. Cox proportional hazard models were used to examine the effect of treatment and prognostic factors on OS. Results: In addition to the significant effect of treatment received, the univariate analysis identified ECOG PS and measurable disease at baseline, time from last dose of D to randomization, time of progression after last D treatment and pain scores at baseline as significant prognostic factors for OS. Interactions of each of these factors with the treatment were not statistically distinct, suggesting that CbzP survival benefit was consistent among the subgroups defined by these factors. After adjustments for all prognostic factors, multivariate analysis identified ECOG PS 2, measurable disease, time of last dose of D to randomization (≤ 6 months vs &gt; 6 months) and presence of baseline pain as statistically significant prognostic factors. Following adjustments, the treatment effect on survival (CbzP vs MP) remained statistically significant (Table). Conclusions: ECOG PS, measurable disease at baseline, time from last D dose to randomization, baseline pain and CbzP treatment predicted OS in patients in the TROPIC study in a multivariate analysis.

Prednisone plus cabazitaxel or mitoxantrone for metastatic castration-resistant prostate cancer progressing after docetaxel treatment : a randomised open-label trial

BACKGROUND: Cabazitaxel is a novel tubulin-binding taxane drug with antitumour activity in docetaxel-resistant cancers. We aimed to compare the efficacy and safety of cabazitaxel plus prednisone with those of mitoxantrone plus prednisone in men with metastatic castration-resistant prostate cancer with progressive disease after docetaxel-based treatment. METHODS: We undertook an open-label randomised phase 3 trial in men with metastatic castration-resistant prostate cancer who had received previous hormone therapy, but whose disease had progressed during or after treatment with a docetaxel-containing regimen. Participants were treated with 10 mg oral prednisone daily, and were randomly assigned to receive either 12 mg/m(2) mitoxantrone intravenously over 15-30 min or 25 mg/m(2) cabazitaxel intravenously over 1 h every 3 weeks. The random allocation schedule was computer-generated; patients and treating physicians were not masked to treatment allocation, but the study team was masked to the data analysis. The primary endpoint was overall survival. Secondary endpoints included progression-free survival and safety. Analysis was by intention to treat. This study is registered at ClinicalTrials.gov, NCT00417079. FINDINGS: 755 men were allocated to treatment groups (377 mitoxantrone, 378 cabazitaxel) and were included in the intention-to-treat analysis. At the cutoff for the final analysis (Sept 25, 2009), median survival was 15·1 months (95% CI 14·1-16·3) in the cabazitaxel group and 12·7 months (11·6-13·7) in the mitoxantrone group. The hazard ratio for death of men treated with cabazitaxel compared with those taking mitoxantrone was 0·70 (95% CI 0·59-0·83, p<0·0001). Median progression-free survival was 2·8 months (95% CI 2·4-3·0) in the cabazitaxel group and 1·4 months (1·4-1·7) in the mitoxantrone group (HR 0·74, 0·64-0·86, p<0·0001). The most common clinically significant grade 3 or higher adverse events were neutropenia (cabazitaxel, 303 [82%] patients vs mitoxantrone, 215 [58%]) and diarrhoea (23 [6%] vs one [<1%]). 28 (8%) patients in the cabazitaxel group and five (1%) in the mitoxantrone group had febrile neutropenia. INTERPRETATION: Treatment with cabazitaxel plus prednisone has important clinical antitumour activity, improving overall survival in patients with metastatic castration-resistant prostate cancer whose disease has progressed during or after docetaxel-based therapy

An international expanded-access programme of everolimus: Addressing safety and efficacy in patients with metastatic renal cell carcinoma who progress after initial vascular endothelial growth factor receptor-tyrosine kinase inhibitor therapy

Background and objectives: The RECORD-1 trial established the clinical benefit of everolimus in patients with metastatic renal cell carcinoma (mRCC) after failure of initial vascular endothelial growth factor receptor-tyrosine kinase inhibitor (VEGFr-TKI) therapy. The REACT (RAD001 Expanded Access Clinical Trial in RCC) study was initiated to address an unmet medical need by providing everolimus prior to commercial availability, and also to further assess the safety and efficacy of everolimus in patients with VEGFr-TKI-refractory mRCC

Temsirolimus, interferon alfa, or both for advanced renal-cell carcinoma

WOS: 000246816500006PubMed ID: 17538086BACKGROUND: Interferon alfa is widely used for metastatic renal-cell carcinoma but has limited efficacy and tolerability. Temsirolimus, a specific inhibitor of the mammalian target of rapamycin kinase, may benefit patients with this disease. METHODS: In this multicenter, phase 3 trial, we randomly assigned 626 patients with previously untreated, poor-prognosis metastatic renal-cell carcinoma to receive 25 mg of intravenous temsirolimus weekly, 3 million U of interferon alfa (with an increase to 18 million U) subcutaneously three times weekly, or combination therapy with 15 mg of temsirolimus weekly plus 6 million U of interferon alfa three times weekly. The primary end point was overall survival in comparisons of the temsirolimus group and the combination-therapy group with the interferon group. RESULTS: Patients who received temsirolimus alone had longer overall survival (hazard ratio for death, 0.73; 95% confidence interval [CI], 0.58 to 0.92; P=0.008) and progression-free survival (P < 0.001) than did patients who received interferon alone. Overall survival in the combination-therapy group did not differ significantly from that in the interferon group (hazard ratio, 0.96; 95% CI, 0.76 to 1.20; P=0.70). Median overall survival times in the interferon group, the temsirolimus group, and the combination-therapy group were 7.3, 10.9, and 8.4 months, respectively. Rash, peripheral edema, hyperglycemia, and hyperlipidemia were more common in the temsirolimus group, whereas asthenia was more common in the interferon group. There were fewer patients with serious adverse events in the temsirolimus group than in the interferon group (P=0.02). CONCLUSIONS: As compared with interferon alfa, temsirolimus improved overall survival among patients with metastatic renal-cell carcinoma and a poor prognosis. The addition of temsirolimus to interferon did not improve survival

Multinational, double-blind, phase III study of prednisone and either satraplatin or placebo in patients with castrate-refractory prostate cancer progressing after prior chemotherapy: the SPARC trial.

Contains fulltext : 79724.pdf (publisher's version ) (Closed access)PURPOSE: This multinational, double-blind, randomized, placebo-controlled, phase III trial assessed the efficacy and tolerability of the oral platinum analog satraplatin in patients with metastatic castrate-refractory prostate cancer (CRPC) experiencing progression after one prior chemotherapy regimen. PATIENTS AND METHODS: Nine hundred fifty patients were randomly assigned (2:1) to receive oral satraplatin (n = 635) 80 mg/m(2) on days 1 to 5 of a 35-day cycle and prednisone 5 mg twice daily or placebo (n = 315) and prednisone 5 mg twice daily. Primary end points were progression-free survival and overall survival (OS). The secondary end point was time to pain progression (TPP). RESULTS: A 33% reduction (hazard ratio [HR] = 0.67; 95% CI, 0.57 to 0.77; P < .001) was observed in the risk of progression or death with satraplatin versus placebo. This effect was maintained irrespective of prior docetaxel treatment. No difference in OS was seen between the satraplatin and placebo arms (HR = 0.98; 95% CI, 0.84 to 1.15; P = .80). Compared with placebo, satraplatin significantly reduced TPP (HR = 0.64; 95% CI, 0.51 to 0.79; P < .001). Satraplatin was generally well tolerated, although myelosuppression and GI disorders occurred more frequently with satraplatin. CONCLUSION: Oral satraplatin delayed progression of disease and pain in patients with metastatic CRPC experiencing progression after initial chemotherapy but did not provide a significant OS benefit. Satraplatin was generally well tolerated. These results suggest activity for satraplatin in patients with CRPC who experience progression after initial chemotherapy
