Overall Survival up for Melanoma Brain Metastases

Excerpt:

“Overall survival (OS) for patients with melanoma brain metastases (MBM) has improved significantly since 2000, according to a study published online Oct. 12 in Cancer.

“Sarah Sloot, M.D., from Groningen University Medical Center in the Netherlands, and colleagues identified 610 patients with unresectable American Joint Committee on Cancer stage III/IV melanoma who received first-line systemic therapy at Moffitt Cancer Center between 2000 and 2012.”

Final TH3RESA, EMILIA Results Confirm Role of Trastuzumab Emtansine in HER2+ Breast Cancer

Excerpt:

“Final results from two large phase III trials confirm that the drug-antibody conjugate trastuzumab emtansine improves overall survival (OS) over other treatment options in patients with previously treated HER2-positive metastatic breast cancer. The results of the EMILIA and TH3RESA trials confirm the agent’s role in this setting.

“Trastuzumab emtansine, which links the antibody trastuzumab with the cytotoxic microtubule inhibitor DM1, was approved based on earlier results of the EMILIA study. The new analysis of that trial offers approximately twice the length of follow-up, at a median of 24.1 months.”

Timing of Surgery After Neoadjuvant Chemoradiation in Stage IIIA NSCLC Impacts Overall Survival

Excerpt:

“The timing of surgery after neoadjuvant chemoradiation in patients with stage IIIA non-small cell lung cancer (NSCLC) affects the overall survival of patients receiving trimodality therapy.

“Approximately one third of all NSCLC patients have locally advanced (stage III, subtypes IIIA and IIIB) disease at the time of diagnosis, with a five-year survival ranging from 7 to 19%. Patients with stage III NSCLC represent a significant clinical challenge due to the poor prognosis associated with this stage of the disease. Trimodality therapy involving the use of radiation concurrently with chemotherapy, otherwise known as neoadjuvant chemoradiation therapy (NCRT), followed by surgery is an acceptable treatment strategy for stage IIIA patients with resectable tumors and limited mediastinal node (N2) involvement. However, trimodality therapy has not been shown to have significant survival advantage over definitive chemoradiation therapy and the optimal interval to surgery (ITS) after completion of NCRT has not been well explored.”

Final OS Analysis Confirms Cobimetinib/Vemurafenib Benefit in Melanoma

Excerpt:

“Combination therapy with cobimetinib (Cotellic) and vemurafenib (Zelboraf) reduced the risk of death by 30% compared with vemurafenib alone in patients with BRAF-positive advanced melanoma, according to the final survival analysis of the phase III coBRIM study that has now been published in The Lancet Oncology.

“The targeted combination improved median overall survival (OS) by 4.9 months versus single-agent vemurafenib (HR, 0.70; 95% CI, 0.55-0.90; P = .005). The OS rates for the combination at 1 and 2 years were 74.5% and 48.3%, respectively.

“ ‘Melanoma is one of the few cancers that has increased in incidence over the past 30 years, and until recently, people with advanced forms of the disease have had few treatment options. Five years ago, the survival of people with advanced melanoma was measured in months, and now we have medicines that are helping people live years,’ Josina Reddy, MD, PhD, senior group medical director at Genentech, the company that manufactures the combination, said in an interview with OncLive.”

Considerations for Single-Agent Versus Combo Melanoma Immunotherapy

Excerpt:

“The combination of ipilimumab (Yervoy) and nivolumab (Opdivo) continues to show promise, with recent data demonstrating a 26% improvement in overall survival (OS) with the 2 drugs compared with ipilimumab alone for patients with advanced melanoma.

“In a 2-year assessment of the phase II CheckMate-069 trial, which was recently presented at the 2016 AACR Annual Meeting, 142 treatment-naïve patients with unresectable stage III or metastatic stage IV melanoma were randomized to receive either the combination (n = 95) or ipilimumab plus placebo (n = 47) every 3 weeks for 4 doses followed by nivolumab or placebo every 2 weeks until disease progression or unacceptable toxicity.

“In the overall treatment population, the 2-year OS rate was 64% with the combination compared with 54% for ipilimumab alone (HR, 0.74; 95% CI, 0.43-1.26). The median OS at 2 years in patients randomized to either the combination or monotherapy has not been reached.”

Steroid Use With Abiraterone Offers Multidimensional Benefits to Patients With mCRPC

Excerpt:

“For decades, the standard of care for men with advanced prostate cancer has been the depletion or inhibition of androgens. While androgen-deprivation therapy (ADT) often results in temporary tumor regression or symptom relief in some patients, disease progression ultimately occurs over time. For patients with metastatic disease, the median overall survival (OS), until very recently, had been less than 2 years after chemotherapy.

“While tumor progression with ADT was previously believed to be hormone-refractory or androgen-independent, a large body of evidence supports that metastatic castration-resistant prostate cancer (mCRPC) is commonly driven by elevated steroid synthesis, increased expression or splice variants of the androgen receptor (AR), or AR ligand promiscuity, indicating the ongoing need for targeted androgen therapies.”

Janssen's Zytiga Boosts Survival in Early-Stage Prostate Cancer

“Janssen has announced data from a post-hoc analysis of a Phase III trial showing that Zytiga plus prednisone boosted overall survival (OS) by 11.8 months compared with placebo plus prednisone, in men with early and less aggressive metastatic castration-resistant prostate cancer (mCRPC) who had not received chemotherapy.

“Data presented today at the European Association of Urology (EAU) 2016 Congress in Munich, Germany, demonstrated that in the COU-AA-302 trial, Zytiga (abiraterone acetate) increased OS to 53.6 months versus the 41.8 months achieved by patients treated with prednisone alone. This benefit was shown to be 4.4 greater than that previously reported for the combo in the final analysis of the COU-AA-302 trial in 2014.

“The post-hoc analysis divided patients into two groups to identify which group experienced a greater treatment benefit. The patients in group 1 were in an earlier, less advanced and less symptomatic stage of the disease, while those in group 2 were in a later, more advanced and more symptomatic stage of the disease.”


Radium-223 Improves QoL Over Placebo in CRPC

“Analyses from the phase III ALSYMPCA trial showed that treatment with the alpha-emitting radiopharmaceutical radium-223 resulted in quality-of-life (QoL) improvements over placebo in patients with castration-resistant prostate cancer (CRPC) and symptomatic bone metastases.

“ ‘Patients with CRPC and bone metastases often present with symptoms such as pain fatigue, anorexia, and, rarely, spinal cord compression, contributing to rapid and significant deterioration in health-related QoL and mortality,’ wrote study authors led by Sten Nilsson, MD, PhD, of Karolinska University Hospital in Stockholm.

“The ALSYMPCA trial found that radium-223 prolonged overall survival (OS) as well as time to first symptomatic skeletal event by significant periods. The trial included prospective QoL measurements using the EuroQoL EQ-5D and the Functional Assessment of Cancer Therapy–Prostate (FACT-P). The results from these tests were published online ahead of print in Annals of Oncology.”


T-DM1 Improved Overall Survival for Heavily Pretreated Patients With HER2-positive Breast Cancer

“Among patients with HER2-positive, metastatic breast cancer that had progressed despite treatment with two or more forms of HER2-targeted therapy (trastuzumab [Herceptin] and lapatinib [Tykerb]), median overall survival was increased for those treated with trastuzumab emtansine (T-DM1 [Kadcyla]) compared with those who received treatment of physician’s choice, according to results from the phase III TH3RESA clinical trial presented at the 2015 San Antonio Breast Cancer Symposium, held Dec. 8–12.

“The HER2-targeted antibody-drug conjugate T-DM1 was approved by the U.S. Food and Drug Administration in February 2013 for treating patients with HER2-positive, metastatic breast cancer that had progressed after treatment with trastuzumab and a taxane.”
