TL;DR: Preliminary data is presented for pts with Her2-positive mUC receiving HER2-targeted treatment with pertuzumab + trastuzumAB with investigator-assessed overall response rate (RECIST v1.1).
Abstract: 348Background: Patients (pts) with mUC have few treatment options beyond the second-line setting. HER2 gene amplification has been reported in a minority of pts with UC, but there have been anecdotal reports of the activity of HER2-targeted agents. MyPathway is a multi-basket study evaluating the efficacy and safety of targeted therapies in non-indicated tumor types harboring relevant molecular alterations. We present preliminary data for pts with HER2-positive mUC receiving HER2-targeted treatment with pertuzumab + trastuzumab. Methods: MyPathway (NCT02091141) is an open-label, multicenter, phase IIA study. Pts in this subset analysis had refractory mUC with HER2 amplification or putative activating mutations by gene sequencing, FISH, or IHC. Pts received standard doses of pertuzumab + trastuzumab without chemotherapy until disease progression or unacceptable toxicity. The primary endpoint is investigator-assessed overall response rate (RECIST v1.1). Results: As of July 31, 2016, 12 pts with platinum-res...

TL;DR: There is already enough circumstantial evidence to justify anti-HER2 therapy alone in selected patients for whom chemotherapy is contraindicated, and trials and prospective studies are now warranted to investigate this issue further.

TL;DR: The model predicted that TDP would be cost-effective as a first-line treatment for HER-2 positive metastatic breast cancer, but only under favorable drug cost assumptions.
Abstract: Objective: To provide perspective for the National Health Insurance Bureau (NHIB), we determined the cost-effectiveness of pertuzumab combined with trastuzumab and docetaxel (TDP) versus trastuzuma...

TL;DR: A variety of novel agents has been tested for hormone-refractory prostate cancer, including pertuzumab and BMS-275291, which may stabilize disease with minimal toxicity, and sipuleucel-T and the combination regimen of docetaxel and DN-101 demonstrate promising preliminary clinical data in terms of improving survival while minimizing toxicity.
Abstract: Purpose of review This review highlights the most interesting developments and outstanding issues surrounding the management of hormone-refractory prostate cancer published in the medical literature during the past year. Recent findings Recent research has reported poor health-related quality-of-life outcomes for patient with hormone-refractory prostate cancer treated in standard clinical practices. In addition, age-related differences in survival appear to exist for patients with hormone-refractory prostate cancer. Two potential future therapies for hormone-refractory prostate cancer, sipuleucel-T and the combination regimen of docetaxel and DN-101, demonstrate promising preliminary clinical data in terms of improving survival while minimizing toxicity. A variety of novel agents has been tested for hormone-refractory prostate cancer, including pertuzumab and BMS-275291, which may stabilize disease with minimal toxicity. In terms of bone-related health, skeletal-related events have been found to be associated with worse survival and health-related quality of life outcomes. Summary Data reported during the past year have implications for future research directions. This direction includes the need for continued exploration of health-related quality of life and age-related outcomes, further study of the disease-stabilizing effects of novel therapies and their translation into improved survival, as well as directed efforts to continue preventing skeletal-related events, which may impact survival and health-related quality of life.

TL;DR: T-DM1+P (w/o T) -> AC substantially improves pCR rates over standard TH -> AC in all 3 HER2+ signatures, including HR+ and HR- subsets, and warrant further investigation of these agents without paclitaxel in a neoadjuvant trial powered for survival endpoints.
Abstract: Background: Pathologic complete response (pCR) is an established prognostic biomarker for aggressive HER2+ breast cancer (BC). Improving pCR rates may identify new therapies that improve survival. T-DM1 and pertuzumab have established benefits in metastatic HER2+ BC. We tested their ability when combined, without paclitaxel, to improve pCR rates (ypT0ypN0) over standard therapy in the randomized, phase 2, I-SPY 2 neoadjuvant trial. Methods: Enrolled patients (pts) had invasive breast cancer ?2.5 cm in HER2-positive subsets. Pts were adaptively randomized to 12 wkly cycles of paclitaxel+trastuzumab (TH, control) or T-DM1+pertuzumab (T-DM1+P) without T, followed by doxorubicin/cyclophosphamide (AC) x 4 and surgery. We utilized all TH control pts accrued over the course of the trial, adjusting for potential differences due to time period treated, which were informed by the several other treatment arms that have been in the trial. Adaptive assignment to the various experimental arms in the trial was based on current Bayesian probabilities of superiority vs. control. “Graduation” by signature and futility stopping were based upon Bayesian predictive probability of success in a future 2-arm, N = 300 neoadjuvant Phase 3 randomized 1:1 trial of T-DM1+P vs. control with pCR endpoint. Results: T-DM1+P met the predictive probability criterion and graduated from I-SPY 2 in 3 signatures: all HER2+, HER2+/HR+, HER2+/HR- (Table 1). Final accrual: 52 T-DM1+P and 31 TH. Safety data will be shown. Conclusions: I-SPY 29s standing platform trial mechanism efficiently evaluates agents in biomarker-defined pt subsets. T-DM1+P (w/o T) -> AC substantially improves pCR rates over standard TH -> AC in all 3 HER2+ signatures, including HR+ and HR- subsets. These findings warrant further investigation of these agents without paclitaxel in a neoadjuvant trial powered for survival endpoints.
