Niraxx Light Therapeutics Announces New Study Validating Personalized Light Therapy

Irvine, Calif.—Niraxx Light Therapeutics, a leader in wearable neurotechnology, today announced recent study findings supporting the company’s personalized PBM (photobiomodulation) light therapy technology platform.

“This is a breakthrough validation on our hypothesis of personalization of PBM,” said Chief Executive and co-founder Joshua Chen, referencing to a joint study between Massachusetts General Hospital (MGH) and NYU Langone Health.

PBM is a form of light-based therapy that applies non-invasive light to neural tissue.

The single-blind, dose-ranging, sham-controlled study looked at dose dependent effects of PBM on adult subjects with major depressive disorder (MDD). Eligible subjects were randomized to receive three experimental doses. Study findings suggested that specific parameters of PBM affect brain hemodynamics and that personalized dose of light helped optimize treatment.

“The joint study has confirmed that personalized PBM dosing is key to MDD treatment,” said lead investigator Dr. Paolo Cassano, MD, PhD. He is Niraxx co-founder and Chair of Scientific Advisory Board, an Assistant Professor of Psychiatry at Harvard Medical, Director of Photobiomodulation at MGH, and a practicing physician. He has over 10 years of experience using PBM to treat patients with depression.

Dr. Cassano stressed the huge unmet need in treating depression, noting that current treatments like medications and psychotherapy are not sufficient due to barriers like side effects and time and cost commitment. “As a community, we need to start offering depression treatments that go beyond the one-size-fits-all approach,” he said.

The COVID-19 pandemic has further negatively increased the prevalence MDD and anxiety. About 4 in 10 adults in the U.S. have reported symptoms of MDD and anxiety, up from one in 10 adults who reported these symptoms in 2019, according to the U.S. Census Bureau. As the pandemic wears on, accessible brain health care becomes even more necessary.

MDD affects more than 16.1 million American adults, or about 6.7% of the U.S. population age 18 and older, according to Anxiety & Depression Association of America. The World Health Organization estimated the common mental health disorder affect more than 264 million people worldwide.
