FDA Approves Axumin to Detect Recurrent Prostate Cancer

Excerpt:

“The FDA today approved Axumin, an injectable radioactive diagnostic agent used to detect recurrent prostate cancer.

“The agent is indicated for PET imaging in men who have suspected prostate cancer recurrence based on elevated PSA levels following treatment.

“The FDA based its decision on results of two studies that evaluated the safety and efficacy of Axumin (Blue Earth Diagnostics). One study compared 105 Axumin scans to histopathology obtained by prostate biopsy and by biopsies of suspicious imaged lesions in men suspected of having prostate cancer recurrence. In the second study, researchers evaluated 96 Axumin scans with C11 choline scans in patients with a median PSA of 1.44 ng/mL.”

FDA Grants Priority Review for Genentech’s Cancer Immunotherapy Atezolizumab in Specific Type of Lung Cancer

Excerpt:

“Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has accepted the company’s Biologics License Application (BLA) and granted Priority Review for atezolizumab (anti-PDL1; MPDL3280A) for the treatment of people with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose disease expresses the protein PD-L1 (programmed death ligand-1), as determined by an FDA-approved test, and who have progressed on or after platinum-containing chemotherapy.

“ ‘In a study of atezolizumab in people with previously treated advanced lung cancer, PD-L1 expression correlated with how well they responded to the medicine,’ said Sandra Horning, M.D., chief medical officer and head of Global Product Development. ‘The goal of PD-L1 as a biomarker is to identify people most likely to benefit from atezolizumab alone.’ ”

FDA Expands Use of Xalkori to Treat Rare Form of Advanced Non-Small Cell Lung Cancer

“The U.S. Food and Drug Administration today approved Xalkori (crizotinib) to treat people with advanced (metastatic) non-small cell lung cancer (NSCLC) whose tumors have an ROS-1 gene alteration. Xalkori is the first and only FDA approved treatment for patients with ROS-1 positive NSCLC.

“Lung cancer is the leading cause of cancer-related deaths in the United States, with an estimated 221,200 new diagnoses and 158,040 deaths in 2015, according to the National Cancer Institute.  ROS-1 gene alterations, thought to lead to abnormal cells, have been identified in various cancers, including NSCLC. ROS-1 gene alterations are present in approximately 1 percent of patients with NSCLC. The overall patient and disease characteristics of NSCLC with ROS-1 gene alterations appear similar to NSCLC with anaplastic lymphoma kinase (ALK) gene alterations, for which crizotinib use was previously approved. Xalkori was approved to treat certain patients with late-stage NSCLC that expresses an abnormal ALK gene in 2011.”


New Treatments for Gastrointestinal Neuroendocrine Tumors


Neuroendocrine tumors of the digestive system (GI-NETs) can arise in different parts of the digestive tract. GI-NETs originating in the ileum, duodenum, and appendix are known as midgut NETs, and tumors of the stomach, colon, and rectum are non-midgut NETs. Many of these tumors are functional; that is, they produce a variety of hormonal substances that cause serious, debilitating symptoms. Continue reading…


FDA Accepts Supplemental Biologics License Application (sBLA) for KEYTRUDA® (pembrolizumab), Merck’s Anti-PD-1 Therapy, in Advanced Non-Small Cell Lung Cancer, and Grants Priority Review

“Merck MRK, -0.23% known as MSD outside the United States and Canada, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the supplemental Biologics License Application (sBLA) for Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), for the treatment of patients with advanced non-small cell lung cancer (NSCLC) whose disease has progressed on or after platinum-containing chemotherapy and an FDA-approved therapy for EGFR or ALK genomic tumor aberrations, if present. The FDA granted Priority Review with a PDUFA, or target action, date of October 2, 2015; the sBLA will be reviewed under the FDA’s Accelerated Approval program.

“ ‘Today’s announcement reflects our commitment to accelerate the development of immunotherapeutic approaches to treat lung cancer, one of the most deadly malignancies,’ said Dr. Roger M. Perlmutter, president, Merck Research Laboratories. ‘We believe that data submitted to the FDA illustrate the significant potential of KEYTRUDA to treat advanced non-small cell lung cancer – and we look forward to working with the FDA to bring our anti-PD-1 therapy to patients afflicted with this devastating cancer.’ “


FDA Grants Orphan Drug Designation to WT1 Cancer Vaccine for Malignant Pleural Mesothelioma

“The FDA granted orphan drug designation to the WT1 cancer vaccine for the treatment of malignant pleural mesothelioma.

“The FDA based the designation on results from a randomized, double blind, placebo-controlled phase 2 trial of the WT1 vaccine (SLS-001, SELLAS Life Sciences) in 40 patients with malignant pleural mesothelioma treated at Memorial Sloan Kettering Cancer Center and The University of Texas MD Anderson Cancer Center.

“Results showed patients assigned the vaccine experienced longer median OS (21.4 months vs. 16.6 months) and median PFS (11.4 months vs. 5.7 months) than those assigned placebo. The vaccine also demonstrated a favorable safety profile, according to researchers.

“A phase 2b/3 trial in malignant pleural mesothelioma is expected to begin by the third quarter of this year.”

 


Another Indication OK'd for Afinitor

“Everolimus (Afinitor) is now approved for treating inoperable, locally advanced or metastatic neuroendocrine tumors of gastrointestinal or lung origin, the FDA said Friday.

“The agency further specified that the tumors should be ‘progressive, well-differentiated [and] non-functional.’

“Approval was based primarily on a 302-patient trial comparing everolimus with placebo, both in combination with best supportive care. Median progression-free survival was 11 months in the active-drug arm compared with 3.9 months for placebo. However, in an interim analysis, there was no difference in overall survival, and response rates (i.e., achieving significant tumor shrinkage) were 2% with everolimus and 1% with placebo.”


FDA Expands Palbociclib Approval for Breast Cancer

“The Food and Drug Administration (FDA) has granted an expanded indication for the cyclin-dependent kinase 4/6 inhibitor palbociclib (Ibrance). The drug is now approved for use in combination with fulvestrant in women with hormone receptor (HR)-positive, HER2-negative advanced or metastatic breast cancer whose disease progressed following endocrine therapy.

“Palbociclib was initially approved in February 2015 for the treatment of estrogen receptor–positive, HER2-negative metastatic breast cancer, in women who had not yet received endocrine therapy. The new approval was granted under the FDA’s breakthrough therapy designation.

“The additional indication for palbociclib is based on results from the PALOMA-3 trial, which was stopped early in April 2015 after an interim analysis showed benefit in combination with fulvestrant when compared to fulvestrant and placebo.”


Pfizer Receives Expanded FDA Approval For IBRANCE (palbociclib) In HR+, HER2- Metastatic Breast Cancer

“Pfizer Inc. (NYSE:PFE) today announced that the U.S. Food and Drug Administration (FDA) has approved a new indication expanding the use of IBRANCE® (palbociclib) 125mg capsules, Pfizer’s metastatic breast cancer therapy. Now IBRANCE also is approved for the treatment of hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer in combination with fulvestrant in women with disease progression following endocrine therapy. Pfizer’s supplemental New Drug Application (sNDA) for IBRANCE was reviewed and approved under the FDA’s Breakthrough Therapy designation and Priority Review programs based on results from the Phase 3 PALOMA-3 trial in pre-, peri- and post-menopausal women with HR+, HER2- metastatic breast cancer whose disease progressed on or after prior endocrine therapy in the adjuvant or metastatic setting.”
