$9 million NIH grant advances drug to treat nicotine addiction

7Newswire

SAN DIEGOFeb. 6, 2024 /7Newswire — Scientists at Camino Pharma, LLC, Sanford Burnham Prebys and University of California San Diego School of Medicine ­­received a $9-million grant (U01DA057847) from the National Institute on Drug Abuse (NIDA) at the National Institutes of Health (NIH). The 3-year grant will fund longer toxicology studies and drug manufacturing of SBP-9330 to support planned Phase 2 studies for nicotine cessation. SBP-9330, a small molecule that was discovered by Dr. Nicholas C­osford and his team at Sanford Burnham Prebys, targets a receptor called metabotropic glutamate receptor 2 (mGlu2), leading to reduced levels of glutamate—a neurotransmitter linked to nicotine addiction and relapse behavior. SBP-9330 works through a mechanism distinct from the currently available drugs and would be a first-in-class medication to help people quit smoking.

The Phase 1 clinical testing of SBP-9330 was recently completed under a previous $11.4-million, 3-year NIDA grant awarded to the same researchers, documenting that the drug candidate is safe and well tolerated in healthy smoking and nonsmoking human subjects. Under the terms of the current grant, investigators at Camino Pharma will oversee the longer-term toxicology studies, Sanford Burnham Prebys will oversee drug manufacturing and formulation, and UC San Diego School of Medicine will provide guidance for the design of the Phase 2 clinical program.

“Our Phase 1 study results showed that SBP-9330 has a favorable safety and tolerability profile and well-behaved pharmacokinetics in humans, supporting further clinical development and evaluation of the compound in a proof-of-concept study in smokers as an aid to smoking cessation,” says co-principal investigator Gonul Velicelebi, Ph.D., CEO and co-founder of Camino Pharma. “We are grateful to NIDA for their sustained support of the SBP-9330 program from preclinical through the clinical stage, awarding three consecutive U01 grants, totaling $31.2 million and underscoring the vital importance of public funding for addiction treatments.”

“SBP-9330 is a positive allosteric modulator (PAM) of mGlu2 and thus represents a new class of drugs for treating substance use disorders. We are optimistic we can expand the indications to other types of addiction beyond nicotine, as supported by our preclinical data in animal models,” states Nicholas Cosford, Ph.D., principal investigator on the grant, professor at Sanford Burnham Prebys and co-founder of Camino Pharma.

“I’m delighted to continue as one of the co-PIs on this project that is part of NIDA’s “Grand Opportunities in Medications Development for Substance-Use Disorders” portfolio. The opportunity to work with a novel drug like SBP-9330 from bench to bedside is exciting. We desperately need additional smoking cessation medications,” says Robert Anthenelli, M.D., co-principal investigator, professor of psychiatry at UC San Diego School of Medicine and a key opinion leader in the smoking-cessation field.

More than one billion people worldwide smoke tobacco, and the advent of electronic cigarettes (e-cigarettes) has caused a sharp increase in young adults who use nicotine—the addictive component of tobacco. Cigarette smoking accounts for approximately 30% of all cancers, including 80% of lung cancer cases, according to the American Cancer Society. Lung cancer remains the number one cause of cancer deaths in the U.S., and more than half of people die within a year of being diagnosed.

About Camino Pharma, LLC (www.caminopharma.com)

Camino Pharma is a San Diego–based start-up focused on discovering and developing first-in-class therapies for patients afflicted with cancer and CNS disorders. We target signaling proteins based on emerging biological concepts and discover novel mechanisms for modulating these targets with small molecule drugs. Our leadership team has proven expertise in the relevant target biology, as well as extensive experience in drug discovery and development. Our goal is to discover and develop novel, first-in-class to treat (1) the most aggressive forms of cancer with currently limited treatment options, and (2) psychiatric disorders that are poorly addressed by current medications, including substance use and major depression. Our innovative technology platform allows for exploiting inadequately served targets that require a highly adaptive and specialized approach to drug discovery. We intend to use our deep understanding in target biology, combined with extremely tailored, cutting-edge discovery technologies, to find novel cures.
