Thesis Summary

Addex Therapeutics is transitioning its pipeline focus toward brain injury recovery (dipraglurant) and chronic cough (GABAB PAM), while benefiting from partnered programs and a 20% equity stake in its spin-out, Neurosterix. While preclinical data for its chronic cough candidate is highly encouraging and partner Indivior has successfully completed IND-enabling studies for substance use disorders, Addex faces severe near-term cash constraints. With only CHF 1.6 million in cash as of December 31, 2025, the current runway only extends through mid-2026. Progression of unpartnered clinical assets is entirely dependent on securing additional external funding or strategic collaborations, making a Hold recommendation appropriate until liquidity is stabilized.

Bear CaseDownside scenario
$1.5025%

Addex fails to secure non-dilutive funding or partnerships for its unpartnered programs, forcing highly dilutive equity raises or program suspensions. Neurosterix's NTX-253 encounters safety or tolerability issues in its Phase 1 trial, impairing the value of Addex's equity investment. Nasdaq delisting pressures intensify if the bid price remains below USD 1.00.

Base CaseCentral scenario
$30.0060%

Addex successfully maintains its lean operating model while its spin-out Neurosterix delivers positive Phase 1 data for NTX-253 in Q2 2026, validating the M4 PAM platform. Partner Indivior advances the GABAB PAM program for substance use disorders into clinical trials, triggering milestone payments. Addex secures a licensing partner or targeted funding to transition its independent chronic cough program into IND-enabling studies, extending its cash runway.

Bull CaseUpside scenario
$12.0025%

Neurosterix's Phase 1 trial of NTX-253 delivers outstanding safety and efficacy signals, triggering a rapid transition to Phase 2 and significantly appreciating Addex's 20% equity stake. Concurrently, Indivior initiates Phase 1 trials for the GABAB PAM substance use disorder program, triggering substantial milestone payments. Addex secures a high-value licensing deal for its independent chronic cough program, fully funding its clinical development and extending the cash runway indefinitely.

Scenarios reflect our research view at the research date.

Key Investment Merits
  • Validated allosteric modulation platform with a partner-backed program (Indivior) eligible for up to USD 330 million in milestones plus royalties.
  • Valuable 20% equity stake in Neurosterix, which is advancing a novel M4 PAM (NTX-253) for schizophrenia with Phase 1 data expected in Q2 2026.
  • Regained full rights to ADX71149 (mGlu2 PAM), providing a second Phase 2-ready clinical asset alongside dipraglurant.

Key Investment Risks
  • Critical cash runway constraints, with CHF 1.6 million in cash as of late 2025 only funding operations through mid-2026.
  • High dependence on securing external partnerships or dilutive capital to advance unpartnered programs into the clinic.
  • Risk of Nasdaq delisting if the company cannot maintain the minimum bid price requirement.

Thesis Invalidation Triggers
  1. Failure of Neurosterix's NTX-253 Phase 1 clinical trial.
  2. Inability to secure new funding or strategic partnerships before the exhaustion of the current cash runway in mid-2026.
  3. Termination or significant delay of the partnered GABAB PAM program by Indivior.
