In the primary analysis of the ERIVANCE BCC trial, vismodegib, the first US Food and Drug Administration-approved Hedgehog pathway inhibitor, showed objective response rates (ORRs) by independent review facility (IRF) of 30% and 43% in metastatic basal cell carcinoma (mBCC) and locally advanced BCC (laBCC), respectively.,ORRs by investigator review were 45% (mBCC) and 60% (laBCC).,Herein, we present long-term safety and final investigator-assessed efficacy results in patients with mBCC or laBCC.,One hundred four patients with measurable advanced BCC received oral vismodegib 150 mg once daily until disease progression or intolerable toxicity.,The primary end point was IRF-assessed ORR.,Secondary end points included ORR, duration of response (DOR), progression-free survival, overall survival (OS), and safety.,At data cutoff (39 months after completion of accrual), 8 patients were receiving the study drug (69 patients in survival follow-up).,Investigator-assessed ORR was 48.5% in the mBCC group (all partial responses) and 60.3% in the laBCC group (20 patients had complete response and 18 patients had partial response).,ORRs were comparable across patient subgroups, including aggressive histologic subtypes (eg, infiltrative BCC).,Median DOR was 14.8 months (mBCC) and 26.2 months (laBCC).,Median OS was 33.4 months in the mBCC cohort and not estimable in the laBCC cohort.,Adverse events remained consistent with clinical experience.,Thirty-three deaths (31.7%) were reported; none were related to vismodegib.,This long-term update of the ERIVANCE BCC trial demonstrated durability of response, efficacy across patient subgroups, and manageable long-term safety of vismodegib in patients with advanced BCC.,This study was registered prospectively with Clinicaltrials.gov, number NCT00833417 on January 30, 2009.,The online version of this article (doi:10.1186/s12885-017-3286-5) contains supplementary material, which is available to authorized users.
Ipilimumab, an antibody that enhances T-cell activation, may augment immunogenicity of tumor cells that are injured by radiation therapy.,We hypothesized that patients with melanoma brain metastasis treated with both ipilimumab and radiotherapy would have improved overall survival, and that the sequence of treatments may affect disease control in the brain.,We analyzed the clinical and radiographic records of melanoma patients with brain metastases who were treated with whole brain radiation therapy or stereotactic radiosurgery between 2005 and 2012.,The hazard ratios for survival were estimated to assess outcomes as a function of ipilimumab use and radiation type.,Seventy patients were identified, 33 of whom received ipilimumab and 37 who did not.,The patients who received ipilimumab had a censored median survival of 18.3 months (95% confidence interval 8.1-25.5), compared with 5.3 months (95% confidence interval 4.0-7.6) for patients who did not receive ipilimumab.,Ipilimumab and stereotactic radiosurgery were each significant predictors of improved overall survival (hazard ratio = 0.43 and 0.45, with P = 0.005 and 0.008, respectively).,Four of 10 evaluable patients (40.0%) who received ipilimumab prior to radiotherapy demonstrated a partial response to radiotherapy, compared with two of 22 evaluable patients (9.1%) who did not receive ipilimumab.,Ipilimumab is associated with a significantly reduced risk of death in patients with melanoma brain metastases who underwent radiotherapy, and this finding supports the need for multimodality therapy to optimize patient outcomes.,Prospective studies are needed and are underway.
