Draig Therapeutics Emerges with $140M Series A to Advance Novel Depression Treatment

Psychiatric medicine startup Draig Therapeutics has emerged from stealth mode, announcing a substantial £107 million ($140 million) Series A funding round to support its ambitious pipeline of brain drugs. The company, spun out of research at Cardiff University in Wales, is set to advance its lead candidate for major depressive disorder into Phase 2 clinical trials by the end of 2025.

Novel Approach Targeting AMPA Receptors

Draig's lead program, DT-101, takes aim at a promising but unproven target in depression treatment: the AMPA receptor. This approach seeks to balance the brain's excitatory and inhibitory activity, addressing the underlying neural imbalances associated with psychiatric conditions.

"We have deep experience putting together trials for neuropsychiatric conditions and will use a range of different strategies to minimize the risk of placebo effects," stated Ruth McKernan, Draig's executive chair, in an email to BioPharma Dive.

Expanding Pipeline and Investor Confidence

Beyond DT-101, Draig is advancing two additional programs targeting GABA-A receptors, drawing comparisons to successful treatments developed by Sage Therapeutics for postpartum depression. While specific indications for these candidates remain undisclosed, the company claims they are "highly selective" with "best-in-class potential."

The substantial Series A funding, led by Access Biotechnology with participation from Canaan Partners, SR One, Sanofi Ventures, and three other investors, reflects growing confidence in psychiatric drug development. This "megaround" joins at least two dozen other biotech startups that have secured over $100 million in venture capital this year alone.

Challenges and Opportunities in Psychiatric Drug Development

Despite the influx of capital and renewed interest in brain drugs, Draig faces significant hurdles. The complex nature of psychiatric disorders and difficulties in clinical trial design, particularly in mitigating placebo responses, have historically made it challenging for new treatments to gain approval.

However, recent breakthroughs and increased investment in the field are spurring optimism. Draig's experienced leadership team, including co-founders John Atack and Simon Ward from Cardiff University's Medicines Discovery Institute, brings valuable expertise to navigate these challenges.

As Draig Therapeutics prepares to initiate Phase 2 studies of DT-101 and advance its broader pipeline, the company's progress will be closely watched by industry observers and potential partners alike. The success of this venture could signal a new era in psychiatric medicine, potentially offering hope to millions affected by depression and related disorders.
