Nirsum Labs

Nirsum is developing new medications for opioid use disorder (OUD), the most significant, neglected public health crisis the US has faced in a generation. OUD kills more Americans yearly than traffic fatalities, HIV at its peak, breast cancer, or cumulative combat deaths in Vietnam. It afflicts young adults in their prime disproportionately, with fatalities averaging ~40 years of age. Even pre-Covid, life expectancy was increasing globally but declined in the US as last seen only during World War I, driven by OUD. And in 2020 opioid deaths increased another ~30% over 2019. The social and economic toll is also significant. The disease has flooded the foster care system with orphaned and near-orphaned children of afflicted parents. OUD cost the US >$1 trillion in 2017 alone. OUD’s insidious impact has reached every corner of American society, politics, culture, and economy.

Medications for OUD (MOUD) plus psychosocial counseling are the gold standard of care. Yet today’s few MOUDs are essentially the same ones from decades ago, then and now inadequate defenses against the tide of addiction. In theory, these MOUD should prevent relapse, but some options are themselves opioids or have short treatment retention. Given their shortcomings, these MOUD are under-prescribed, offered to <20% of patients. Patients seeking abstinence in detoxification programs, go home un-initiated onto MOUD in an estimated ~95% of cases, only to predictably relapse. The systematic lapse of MOUD initiation in such patients results from dissatisfaction with available options, as evidenced in national treatment guidelines. OUD patients are left stigmatized with the false narrative that durable opioid independence is unattainable.

History has shown that other diseases where false narratives once prevailed can change upon the advent of innovative medicines. Depression was regarded an inherited “weakness;” HIV was deemed “God’s wrath”. Such beliefs were dispelled once breakthrough medications arose, demonstrating disease treatability and de-stigmatizing victims. Similarly, with innovation, the narrative will shift for OUD.

Awareness for OUD is already improving. It was declared a Public Health Emergency in 2017. Beating OUD is a bipartisan national imperative: the SUPPORT Act of 2019 passed 99 to 1 in the Senate. In cooperation with the National Institutes of Health (HEAL Initiative award UG3DA048234), Nirsum is all-in on the fight. Just as second generation HIV therapies drove AIDS mortality down >70% from US epidemic peaks, our mission is to do the same for OUD.
