Proteolix, Inc., was a private biotechnology company with headquarters in South San Francisco, California. Proteolix was founded in 2003 based on technology developed by co-founders Craig M. Crews (Yale University) and Raymond J. Deshaies (California Institute of Technology). Susan Molineaux and Phil Whitcomeref> "Paid Notice: Deaths WHITCOME, DR. PHILIP J." The New York Times. 2005-12-18. ISSN 0362-4331 . Retrieved 2024-06-19.</ref> joined as co-founders.
Proteolix was launched based on an $18.2 million A round comprising investments by Latterell Venture Partners, US Venture Partners, Advanced Technology Ventures, and The Vertical Group. Its lead product candidate, carfilzomib (PR-171), is a tetrapeptide epoxyketone for treating multiple myeloma, a blood cancer. The drug carfilzomib works by preventing proteasomes from breaking down other proteins. Proteolix focused primarily on the proteasome as a therapeutic target. [1]
At the time of its sale (see below), the company had two earlier-stage programs, an orally-bioavailable proteasome inhibitor for oncology (PR-047), and an agent preferentially targeting the immuno form of the proteasome (PR-957), with potential utility in areas such as rheumatoid arthritis. At the time of sale, carfilzomib's route of administration was intravenous, and the company was exploring its potential utility in multiple myeloma, Non-Hodgkin lymphoma (NHL) and other cancers.
Proteolix was acquired by Onyx Pharmaceuticals in 2009 for $810 million (nominal value). PR-171 is sold by Onyx Pharmaceuticals as Kyprolis. Onyx renamed PR-047 to "ONX 0912" and PR-957 to "ONX 0914". Onyx Pharmaceuticals is a subsidiary of Amgen.
Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. Often, no symptoms are noticed initially. As it progresses, bone pain, anemia, renal insuficiency, and infections may occur. Complications may include hypercalcemia and amyloidosis.

The mission of the Multiple Myeloma Research Consortium (MMRC) is to champion collaboration with and integration across academia and industry and to focus on speed and innovation to bring the most promising multiple myeloma treatments to patients faster. It was founded by Kathy Giusti, a myeloma patient and founder and chief executive officer of the Multiple Myeloma Research Foundation (MMRF).
Salinosporamide A (Marizomib) is a potent proteasome inhibitor being studied as a potential anticancer agent. It entered phase I human clinical trials for the treatment of multiple myeloma, only three years after its discovery in 2003. This marine natural product is produced by the obligate marine bacteria Salinispora tropica and Salinispora arenicola, which are found in ocean sediment. Salinosporamide A belongs to a family of compounds, known collectively as salinosporamides, which possess a densely functionalized γ-lactam-β-lactone bicyclic core.
Nereus Pharmaceuticals was a pharmaceutical company focused on the development of natural products from marine microbial and other natural sources into small molecule human therapeutics. The major disease area addressed by Nereus is cancer. Nereus was purchased by Triphase Research and Development in 2012.

Carfilzomib, sold under the brand name Kyprolis, is an anti-cancer medication acting as a selective proteasome inhibitor. Chemically, it is a tetrapeptide epoxyketone and an analog of epoxomicin. It was developed by Onyx Pharmaceuticals.
Santaris Pharma A/S was a biopharmaceutical company founded in 2003 in Copenhagen, Denmark. The company also had a branch in San Diego, California that opened in 2009. Created by a merger between Cureon and Pantheco, Santaris developed RNA-targeted medicines using a Locked Nucleic Acid (LNA) Drug Platform and Drug Development Engine.
Onyx Pharmaceuticals Inc. has been a biopharmaceutical company headquartered in South San Francisco, California. The company developed and marketed medicines for the treatment of cancer. Onyx was founded in 1992 by Kevin J. Kinsella and Frank McCormick Ph.D., FRS. McCormick served as the chief scientific officer until 1998, while Kinsella was the firm's chairman. In 2009, the company acquired Proteolix, Inc., a private biotechnology company, for $276 million in cash plus additional milestone payments. In January 2012, the company was named "the top biotechnology takeover target in 2012" through an industry survey. Onyx president and chief executive officer (CEO) Tony Coles had said that Onyx liked its prospects as an independent company and was focused on bringing new therapies to patients. However, at the end of August 2013, Amgen announced it was acquiring Onyx in an agreed $10.4 billion deal.

Craig M. Crews is an American scientist at Yale University known for his contributions to chemical biology. He is known for his contributions to the field of induced proximity through his work in creating heterobifunctional molecules that "hijack" cellular processes by inducing the interaction of two proteins inside a living cell. His initial work focused on the discovery of PROteolysis-TArgeting Chimeras (PROTACs) to trigger degradation of disease-causing proteins, a process known as targeted protein degradation (TPD), and he has since developed new versions of -TACs to leverage other cellular processes and protein families to treat disease.
ONX-0801 is an experimental drug that has been developed to target ovarian cancer. It is a folate receptor alpha mediated thymidylate synthase inhibitor.
Raymond Joseph Deshaies is an American biochemist and cell biologist. He is senior vice president of global research at Amgen and a visiting associate at the California Institute of Technology (Caltech). Prior to that, he was a professor of biology at Caltech and an investigator of the Howard Hughes Medical Institute. He is also the co-founder of the biotechnology companies Proteolix and Cleave Biosciences. His research focuses on mechanisms and regulation of protein homeostasis in eukaryotic cells, with a particular focus on how proteins are conjugated with ubiquitin and degraded by the proteasome.
