About the consortium
The UC Drug Discovery Consortium aims to support early drug discovery projects on UC campuses by sharing resources and expertise. The consortium launched with the help of a UC grant to the Drug, Device, Discovery and Development workgroup of UC Biomedical Research Acceleration, Integration and Development. The consortium’s co-principal investigators are:
For 12 years, UCLA researcher Dennis Slamon pursued a groundbreaking approach to treating breast cancer: attack the disease genetically.
The journey was long and filled with obstacles, but his persistence paid off.
Slamon and colleagues conducted laboratory and clinical research that, in collaboration with biotechnology firm Genentech, helped lead to development of the breast cancer drug Herceptin.
The drug, which targets a specific genetic alteration found in about 25 percent of breast cancer patients, has saved thousands of women’s lives. Lifetime even made a movie based on Slamon’s struggles, “Living Proof,” starring Harry Connick Jr.
But not all drug discovery efforts have a Hollywood ending.
The odds of developing a blockbuster drug are slim. Thousands of compounds are screened, and only about 1 in 10 drugs that survive the initial stages to enter clinical trials eventually receives approval. The road from discovery to drug product can take more than a decade and cost more than $2 billion.
How can the drug discovery process be improved?
The newly launched University of California Drug Discovery Consortium aims to tackle that problem by working together as a UC system to speed and increase development of a range of drugs to help patients. This not only could help generate life-saving treatments, but also create significant economic activity from spinoff companies to licenses and collaborations with industry.
“The leap from academic discovery to drug product is time consuming and costly,” said Catherine Tralau-Stewart, UC San Francisco associate professor of therapeutics and campus lead for the consortium. “We’re trying to improve how we support drug discovery across the UC campuses. We’re hopeful that the end result will be more innovative UC therapeutics reaching patients. The development of industrial, philanthropic and investment partnerships will be a key part of the consortium.”
Translating research into therapies
Tralau-Stewart is principal investigator on a $2.2 million, three-year grant from UC’s Multicampus Research Programs and Initiatives focusing on early translation of academic discovery research into therapies. The grant to the Drug, Device, Discovery and Development workgroup of UC Biomedical Research Acceleration, Integration and Development is helping to get the consortium off the ground.
The consortium brings together UC’s five medical center campuses — Davis, Irvine, Los Angeles, San Diego and San Francisco — to share resources and expertise to help develop new drugs.
“We’re trying to change the ecosystem of drug development in California,” said Robert Damoiseaux, UCLA associate professor of pharmacology, director of the Molecular Screening Shared Resource in the California NanoSystems Institute and campus lead for the consortium.
UC researchers have a history of helping to discover drugs that improve the lives of patients, though even the successes illustrate the lengthy process:
- Ocrevus: A new multiple sclerosis drug approved this year, Ocrevus grew out of research began 40 years ago by Stephen Hauser, chair of neurology at UCSF. The drug holds new hope for the hundreds of thousands Americans living with the disease.
- Semisynthetic artemisinin: Twelve years after a breakthrough discovery in his UC Berkeley lab, chemical engineering professor Jay Keasling began to see results. In 2013, pharmaceutical company Sanofi and nonprofit PATH launched large-scale production of a partially synthetic version of artemisinin, a chemical critical to making today’s front-line antimalaria drug, based on Keasling’s discovery.
- Xtandi: In 2016, UCLA sold its royalty interest connected with a leading prostate cancer medication, Xtandi, whose development was based on discoveries by campus researchers that began in the early 2000s. UCLA will use its share of the proceeds — approximately $520 million — to support research programs aimed at generating additional discoveries that lead to medications and other products that serve the public good.
Damoiseaux has seen the challenges and obstacles to drug discovery. He is developing an online compendium of resources for the UC system to help researchers on each step of the discovery pipeline.
“The drug discovery process can be very complex,” Damoiseaux said. “We’re trying to close the gap.”
UC held its first systemwide drug discovery symposium in February at the California NanoSystems Institute, where UC scientists shared stories of their drug discovery efforts, compared notes on best approaches and a panel of industry experts discussed how to best work with industry to translate drug candidates into the clinic.
The consortium will provide a platform for continuing that collaboration, with researchers aiming to find treatments for a range of diseases from cancer to other unmet needs. For example, the Center for Discovery and Innovation in Parasitic Diseases at UC San Diego targets diseases affecting hundreds of millions of people worldwide, but which are not normally lucrative for traditional drug and vaccine discovery companies because they primarily affect the poor and underserved.
Damoiseaux already has started collaborating with Hartmut Luecke, a UC Irvine professor of molecular biology and biochemistry. They have identified small molecules that could lead to new life-saving treatments to combat the bacterium H. pylori, which is the main cause of stomach cancer and difficult to eradicate with antibiotics.
“We want to help move interesting and innovative ideas along the drug discovery pipeline to help attract other investments, grants, licenses and collaborations with industry, and generate spinoff companies,” Damoiseaux said.
Tralau-Stewart agreed, emphasizing the value in UC-wide collaboration.
“Each campus has its success stories,” Tralau-Stewart said. “It’s the tip of the iceberg of what could be achieved across the UC system. That’s what the UC Drug Discovery Consortium is trying to change.”
