Halozyme Therapeutics, Inc. is an American biotechnology company. It develops oncology therapies designed to target the tumor microenvironment.
The company was founded in 1998 and went public in 2004. Halozyme is headquartered in San Diego, California. [2]
Halozyme's business is primarily focused on its proprietary and patented recombinant human hyaluronidase enzyme, rHuPH20. [2] The company's development pipeline is concentrated in clinical stage and pre-clinical stage oncology products, including its proprietary investigational drug, PEGPH20, a pegylated version of rHuPH20, which targets hyaluronan (HA) high tumors. The company is in various phases of clinical trials with PEGPH20 across multiple solid tumor types, including pancreatic cancer, non-small cell lung cancer (NSCLC), and gastric cancer, to test the drug's safety and efficacy. [3] Halozyme has one FDA approved product (Hylenex recombinant, hyaluronidase human injection [4] [5] ). The company also licenses its drug delivery technology Enhanze [6] to other biopharmaceutical companies, including Roche, Baxalta, Pfizer, Janssen, AbbVie, Bristol Myers Squibb and Lilly. [3]
Since January 2014, Helen Torley has been Chief Executive Officer and President of Halozyme.
Hylenex: Approved by the U.S. Food and Drug Administration (FDA) on 12/02/2005. [4] Hylenex is a hyaluronidase (human recombinant) injection indicated for use in subcutaneous fluid administration, dispersion and absorption of injected drugs, and subcutaneous urography. [7]
Enhanze: Uses recombinant human hyaluronidase to degrade HA and aids in the absorption and dispersion of co-administered injected drugs. Halozyme licenses its Enhanze drug delivery platform technology to other biopharmaceutical companies to enable intravenous to subcutaneous administration conversion and dose optimization. [8]
PEGPH20: A PEGylated drug candidate based on Halozyme's proprietary rHuPH20 enzyme (a recombinant human hyaluronidase enzyme). [9] It breaks down or depletes hyaluronan (HA), [10] which can build up in certain tumors. The goal of PEGPH20 is to break down HA so that some anti-cancer therapies and activated immune cells can better reach the cancer cells of HA-high tumors. [3] [11] On November 4, 2019, Halozyme announced it has halted development of PEGPH20. [12]
PEG-ADA2: An engineered human recombinant enzyme, adenosine deaminase 2, for decreasing the concentration of immune-suppressive adenosine in the tumor microenvironment, and PEGylated to prolong its circulation in the body. It has been tested in colon, lung, and pancreatic cancer models in preclinical studies. [13]
HTI-1511 Anti-EGFR ADC: An antibody-drug conjugate (ADC) with a strong cytotoxin, monomethyl auristatin E, designed to treat EGFR-positive tumors, including those with KRAS and BRAF mutations. It has been tested in colon, lung, and cholangiocarcinoma models in preclinical studies. [13]
Halozyme has many ongoing and completed clinical trials testing the safety and efficacy of its primary investigational drug, PEGPH20, in combination with other therapies, with the goal of finding new treatments for pancreatic cancer, NSCLC, gastric cancer, breast cancer, and others. [2] As of October 2016, the company was sponsoring or collaborating on several clinical trials that were recruiting patients, including:
Hyaluronidases are a family of enzymes that catalyse the degradation of hyaluronic acid. Karl Meyer classified these enzymes in 1971, into three distinct groups, a scheme based on the enzyme reaction products. The three main types of hyaluronidases are two classes of eukaryotic endoglycosidase hydrolases and a prokaryotic lyase-type of glycosidase.
Gemcitabine, sold under the brand name Gemzar, among others, is a chemotherapy medication used to treat cancers. It is used to treat testicular cancer, breast cancer, ovarian cancer, non-small cell lung cancer, pancreatic cancer, and bladder cancer. It is administered by intravenous infusion. It acts against neoplastic growth, and it inhibits the replication of Orthohepevirus A, the causative agent of Hepatitis E, through upregulation of interferon signaling.
Axitinib, sold under the brand name Inlyta, is a small molecule tyrosine kinase inhibitor developed by Pfizer. It has been shown to significantly inhibit growth of breast cancer in animal (xenograft) models and has shown partial responses in clinical trials with renal cell carcinoma (RCC) and several other tumour types.
Ramucirumab, sold under the brand name Cyramza, is a fully human monoclonal antibody (IgG1) used for the treatment of cancer. Ramucirumab is a human vascular endothelial growth factor receptor 2 (VEGFR2) antagonist. Ramucirumab was developed by ImClone Systems. It was isolated from a native phage display library from Dyax.
Tigatuzumab (CS-1008) is a monoclonal antibody for the treatment of cancer. As of October 2009, a clinical trial for the treatment of pancreatic cancer, Phase II trials for colorectal cancer, non-small cell lung cancer, and ovarian cancer have been completed.
Veliparib (ABT-888) is a potential anti-cancer drug acting as a PARP inhibitor. It kills cancer cells by blocking a protein called PARP, thereby preventing the repair of DNA or genetic damage in cancer cells and possibly making them more susceptible to anticancer treatments. Veliparib may make whole brain radiation treatment work more effectively against brain metastases from NSCLC. It has been shown to potentiate the effects of many chemotherapeutics, and as such has been part of many combination clinical trials.
Treatment of lung cancer refers to the use of medical therapies, such as surgery, radiation, chemotherapy, immunotherapy, percutaneous ablation, and palliative care, alone or in combination, in an attempt to cure or lessen the adverse impact of malignant neoplasms originating in lung tissue.
Lipoplatin is a nanoparticle of 110 nm average diameter composed of lipids and cisplatin. This new drug has successfully finished Phase I, Phase II, and Phase III human clinical trials. It has shown superiority to cisplatin in combination with paclitaxel as a chemotherapy regimen in non-small cell lung cancer (NSCLC) adenocarcinomas.
Pelareorep is a proprietary isolate of the unmodified human reovirus being developed as a systemically administered immuno-oncological viral agent for the treatment of solid tumors and hematological malignancies. Pelareorep is an oncolytic virus, which means that it preferentially lyses cancer cells. Pelareorep also promotes an inflamed tumor phenotype through innate and adaptive immune responses. Preliminary clinical trials indicate that it may have anti-cancer effects across a variety of cancer types when administered alone and in combination with other cancer therapies.
Nivolumab, sold under the brand name Opdivo, is an anti-cancer medication used to treat a number of types of cancer.
