In the last several months, three novel drugs that we have been following on this blog failed in late stage clinical trials. The drugs have diverse mechanisms of action:

Vanquish Oncology – Procaspase 3 Activation Factor to Selectively Induce Apoptosis
Procaspase-3 is an executioner protein catalyzes the hydrolysis of more than 100 protein targets. These cleavage events ultimately lead to cell suicide, or apoptosis. Caspase-3 is triggered by the intrinsic and extrinsic apoptosis cascades. Continue reading
Cell-based Immunotherapies in the News
Baxalta, the biopharmaceutical spinoff of Baxter, entered into a $1.7 B deal with Precision BioSceinces for 6 CAR-T (Chimeric Antigen Receptor T-cell) projects, and Saronic Biotechnology announced positive data in preclinical studies of its autologous dendritic cell vaccine for hepatocellular carcinoma. Continue reading
Halaven Shows Survival Advantage in Liposarcoma – FDA Approved
Halaven (eribulin mesylate) was approved by the FDA for the treatment of patients with unresectable or advanced liposarcoma. The treatment is approved for patients who previously had undergone chemotherapy with an anthracycline drug. It was previously approved for patients with breast cancer who had undergone at least two prior chemotherapeutic regimens, including an anthracycline and a taxane. Continue reading
Precision Medicine MATCH Trial Difficulties with Biopsy Specimens
The National Cancer Institute launched the MATCH trial in August 2015 as part of the Precision Medicine Initiative announced by President Obama. Continue reading
Melanocytes Must Regain Primitive, Early Embryologic State to Develop Melanoma
Researchers working with the zebrafish melanoma model have determined that oncogene activation and crippling of tumor suppressors genes is not sufficient to transform melanocytes into melanoma cells. It is essential that the cells re-acquire primordial characteristics, as well. Continue reading
BET Bromodomain Inhibition in Prostate Cancer Treatment
BET bromodomain inhibitors are epigenetic regulators that act by repressing expression of oncogenes, including MYC and BCL-2, that are aberrantly highly expressed in many cancer cells, resulting in inhibited cell proliferation and induction of apoptotic cell death. Continue reading
Argos’ Metastatic Renal Cell Carcinoma Study Passes Independent Data Safety Monitoring Committee Second Interim Analysis
An independent data monitoring committee (IDMC) has recommended the continuation of Argos’ pivotal phase 3 ADAPT clinical trial of AGS-003 for the treatment of metastatic renal cell carcinoma (mRCC) based on results of the committee’s second planned interim data analysis. The next planned interim analysis will be in 6 months. Continue reading
Biomarkers for Wnt activation Predict For HER-2(-) Breast Cancer and NSCLC Response to Vantictumab
OncoMed is developing several compounds that target Wnt and Notch pathways, which are important in cancer and cancer stem cell maintenance, survival, and proliferation. Biomarkers for response of Her-2-negative breast cancer and non-small cell lung cancer (NSCLC) following treatment with Vantictumab, anti-Wnt monoclonal antibody, have been developed. Continue reading
Tazemetostat Histone Methyltransferase Inhibitor for Hematologic and Solid Tumors
Tazemetostat is a small molecule inhibitor of EZH2 being developed by Epizyme, Inc for the treatment of patients with Non-Hodgkin Lymphoma, including germinal center and non-germinal center diffuse large B-cell lymphoma and follicular lymphoma, as well as genetically-defined solid tumors. In many human cancers, misregulated EZH2 enzyme activity results in misregulation of genes that control cell proliferation—without these control mechanisms, cancer cells are free to grow rapidly.
