An indirect comparison of the toxicity of sunitinib and pazopanib in metastatic clear cell renal cancer
No full text<p>Background -Both sunitinib and pazopanib are widely used as first line therapy in metastatic renal cancer (mRCC). The efficacy of these agents appears similar but they may have distinct toxicity profiles. In this study we compare the severity of symptomatic and asymptomatic toxicity associated with sunitinib and pazopanib.</p>
<p>Methods - Two sequential prospective single arm phase II studies investigated either 12 weeks of sunitinib (n = 43) or pazopanib (n = 34) prior to nephrectomy in untreated mRCC. Toxicity was defined as either symptomatic (hand and foot syndrome, mucositis, nausea, fatigue, diarrhoea, oedema, headache, pain, anorexia and change in taste) or asymptomatic (liver toxicity or haematological toxicity). Pazopanib (800 mg once daily (OD)) and sunitinib (50 mg 4/2) were given. Regular Common Toxicity Criteria (CTC) toxicity assessment was performed during the first 12 weeks of therapy.</p>
<p>Results - There was no significant difference in the overall number of toxic events (grade 1–4) for sunitinib and pazopanib (mean number of toxic events/patients: 1.97 versus 1.96: p > 0.05). Increased grade 2–4 symptomatic toxicity events occurred with sunitinib (hazard ratio (HR) 1.67 [95% confidence interval (CI): 1.11–2.56] p 0.03). Sunitinib was associated with an increased grade 2–4 mucositis (16% versus 0% p = 0.02) and fatigue (42% versus 15% p = 0.01). Pazopanib was associated with more frequent grade 1 diarrhoea (39% versus 12%: p = 0.03). Dose reductions for symptomatic toxicity occurred more frequently with sunitinib (26% versus 6% p < 0.05). There was no difference in the occurrence of asymptomatic toxicity.</p>
<p>Conclusion - This indirect analysis suggests sunitinib and pazopanib have distinct toxicity profiles which may help guide patient’s choice. Further comparative data from randomised trials are awaited.</p>
A phase Ib study investigating the combination of everolimus and dovitinib in vascular endothelial growth factor refractory clear cell renal cancer
No full textBackgroundEverolimus (mammalian target of rapmaycin (mTOR) inhibitor) and dovitinib (vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF-2) inhibitor) demonstrate activity in metastatic clear cell renal cancer. The combination of these agents has a broad spectrum of relevant activity. The combination is explored in this phase Ib study.MethodsPatients with metastatic clear cell renal cancer who have failed VEGF targeted therapy were eligible. Up to four cohorts of three to six patients (3+3 design) were treated with escalating doses of everolimus and dovitinib. Dose-limiting toxicities (DLTs) were assessed to determine the maximum tolerated dose (MTD). An expansion cohort (n = 15) was investigated to obtain additional efficacy information. Sequential fluorodeoxyglucose positron emission tomography (FDG-PET) was used as a surrogate marker of response.ResultsOverall 18 patients were recruited into the study. Fifteen patients received the MTD, which was everolimus 5 mg orally (PO) once daily (OD) and dovitinib 200 mg PO day 1–5/7. The MTD was associated with toxicity, which included fatigue, mucositis and diarrhoea in 73%, 53% and 53% (Common Toxicity Criteria (CTC) grade 1–4) of patients, respectively. Frequent biochemical abnormalities occurred (such as hypertriglyceridaemia in 67%). Higher doses of the combination were not tolerable due to grade 3 fatigue in 2/3 patients and grade 3 nausea in 1/3 patients within 1 month of therapy. The response rate at the MDT was 1/15 (7%) while the progression free survival for the MTD was 7 months (95% confidence interval (CI) 2.2–11 months). Pharmacokinetic data at the MTD showed stable kinetics with time.ConclusionDovitinib and everolimus had modest activity, but did not meet all of the planned efficacy end-points. Fatigue was the dose limiting toxicity
Androgen deprivation in testicular cancer by way of macroprolactinoma - balancing the two pathologies

No full textAbstract The treatment landscape of metastatic hormone-sensitive prostate cancer (mHSPC) has changed radically in recent years. Androgen deprivation therapy (ADT) alone was for decades the standard of care for treating mHSPC. This changed when studies showed that the addition of docetaxel chemotherapy or abiraterone acetate to ADT significantly increases overall survival of patients with mHSPC, followed by more recent evidence showing the efficacy of androgen receptor antagonists, such as enzalutamide and apalutamide, in this setting. While this rapid therapeutic evolution is welcome, it presents clinicians with a crucial challenge: the choice of treatment selection and sequencing. In the first-line setting there are no comparative data currently available to guide treatment choice between the different available regimens, and no prospective data to guide clinical decision after progression. Decisions on treatment will now need to be personalised based on indirect comparison of the available efficacy data from multiple phase 3 studies, together with considerations of disease volume, comorbidities, treatment aims, toxicity profile and cost reimbursement within the healthcare setting. Here, we provide an overview of the clinical trial data to date and propose some biological and clinical insights which may be helpful in making decisions on treatment selection and sequencing
