Safety and Tumor Responses with Lambrolizumab (Anti–PD-1) in Melanoma

“The programmed death 1 (PD-1) receptor is a negative regulator of T-cell effector mechanisms that limits immune responses against cancer. We tested the anti–PD-1 antibody lambrolizumab (previously known as MK-3475) in patients with advanced melanoma.”


Immunotherapies Offer Bright Prospects in Advanced Melanoma

“Inspired by the 2011 approval of ipilimumab, the immunotherapy paradigm is experiencing a fervent revival in metastatic melanoma. As attendees heard at the Melanoma/Skin Cancers Oral Abstract Session on Saturday afternoon, three novel strategies that provoke the body’s immune system to attack melanomas are enabling patients to live better and longer with their disease, further fueling the remarkable advances achieved in the field over the past 2 years.”


Researchers Provide Rationale for Use of Targeted Immunotherapy in Sarcomatoid Lung Carcinomas


Phase I Trial Suggests Ipilimumab and PD-1 Drug Nivolumab May Be Better Together than Alone for Advanced Melanoma

“Results from a phase I study show that combination therapy with ipilimumab (Yervoy) and the investigational antibody drug nivolumab led to lasting tumor shrinkage in approximately half of patients with aggressive, advanced melanoma. The results will be presented at the 2013 ASCO Annual Meeting in Chicago…”


Merck Announces Breakthrough Therapy Designation for Lambrolizumab an Investigational Antibody Therapy for Advanced Melanoma

“Merck (NYSE: MRK), known as MSD outside the United States and Canada, announced today that the U.S. Food and Drug Administration (FDA) has designated lambrolizumab (MK-3475) as a Breakthrough Therapy for the treatment of patients with advanced melanoma. Lambrolizumab is Merck’s investigational antibody therapy targeting Programmed Death receptor (PD-1) that is currently being evaluated for the treatment of patients with advanced melanoma, and other tumor types.”


Sizing up a slow assault on cancer

Rise of immunotherapies spurs search for markers of response — Jedd Wolchok braced himself as he walked into the examination room to deliver bad news to his patient. Scans showed that the man’s advanced melanoma had spread, and new tumours had sprouted, even though he had received an experimental therapy called ipilimumab (Yervoy) to rally his immune system against the disease…”


Immunotherapies Take Center Stage in Treatment of Metastatic Melanoma


The promise of immunotherapy is coming to fruition with therapeutic advances in melanoma. In 1998, high-dose interleukin-2 (HD IL-2) became the first U.S. Food and Drug Administration (FDA)-approved immunotherapy for metastatic melanoma. But HD IL-2 is severely toxic and benefits only a small minority of patients. In 2011, ipilimumab became the second immunotherapy approved for metastatic melanoma. Continue reading…


Avastin-Containing Chemotherapy May Be Safe in Lung Cancer Patients with Brain Metastases

Bevacizumab (Avastin), which is approved for treatment of a number of advanced-stage cancer types, is commonly avoided in patients with brain metastases (cancer that has spread to the brain) because of fear of brain hemorrhages (bleeding in the brain). A retrospective study of 52 patients with advanced non-small cell lung cancer (NSCLC) who had received chemotherapy containing Avastin found no cases of serious bleeding events and no significant differences in survival or treatment side effects between patients with or without brain metastases. Avastin may therefore be a safe treatment option in NSCLC with brain metastases.

Overexpression of IGF1R and EGFR Genes May Worsen Lung Cancer Prognosis

The roles of the genes IGF1R and EGFR in lung cancer were examined in patients with non-small cell lung cancer (NSCLC) who had their primary tumor surgically removed. Patients whose tumors had increased expression of both IGFR1R and EGFR were more likely to experience recurrence of the cancer after a shorter amount of time and had shorter survival times after surgery. This finding suggests that concurrent overexpression of IGF1R and EGFR is a negative prognosis factor in NSCLC and may indicate patients who are more likely to benefit from novel treatments with IGF1R inhibitors.
