3 Drug Candidates2 Trials

Reconnect Labs AG is a Swiss clinical-stage company and University of Zurich spin-off developing precision psychopharmacology therapeutics, including sublingual DMT/harmine, sublingual 5-MeO-DMT, and sublingual dexmedetomidine. Founded in 2021 by Dr. Davor Kosanic (CEO) and co-founders from the Psychiatric University Clinic Zurich and ETH Zurich, building on ~30 years of in-human psychedelic research. The company raised CHF 22M+ (CHF 12M equity across Seed 2021 and Series A 2023–2025; CHF 10M in competitive grants from investors including Esperante Ventures, Lionheart Ventures, Negev Capital, and Noetic Fund) before emerging from stealth in August 2025. Their microcarrier-based transmucosal delivery platform (exclusively licensed) dramatically reduces inter-subject PK variability for DMT/harmine vs. oral ayahuasca and eliminates vomiting. RE03 (sublingual dexmedetomidine for insomnia in PTSD) is the most advanced programme with Swissmedic approval and FDA accelerated pathway confirmed.

RE03 (Sublingual Dexmedetomidine)

Phase II

Sublingual dexmedetomidine for insomnia in PTSD. Dexmedetomidine is an alpha-2 adrenergic agonist already FDA-approved as IV sedative (Precedex) and sublingual for agitation (Igalmi/BXCL501). RE03 repurposes for PTSD-associated insomnia. Phase 2a actively recruiting (NCT06685965). FDA accelerated development pathway confirmed. Publication in Anesthesiology (March 2025).

Phase IIActive

Forecast

Phase II topline - Likely: Q4 2026

RE03 Phase 2a is recruiting in PTSD-related sleep disturbance. Reconnect announced first patient enrollment on 2025-10-20, and ClinicalTrials.gov lists estimated study completion in August 2026.

Milestones

regulatory-milestone

Completed

Actual: Jan 1, 2025

FDA confirms accelerated development pathway for RE03 (sublingual dexmedetomidine) for insomnia in PTSD.

Why it matters: FDA accelerated pathway reduces development timeline and cost. Leverages existing dexmedetomidine safety database (IV Precedex approved 1999, sublingual Igalmi approved 2022). PTSD-associated insomnia has no FDA-approved treatment — unmet medical need designation likely.

data-readout

Completed

Actual: Mar 1, 2025

Publication in Anesthesiology (March 2025) supporting sublingual dexmedetomidine mechanism for insomnia. Provides preclinical/translational evidence for RE03 approach in PTSD-associated sleep disturbance.

Why it matters: Peer-reviewed publication in a top-tier journal (Anesthesiology) validates the mechanistic rationale. Dexmedetomidine produces a unique sleep-like sedation pattern (mimics natural sleep architecture) — distinct from benzodiazepines or z-drugs that disrupt REM sleep.

Trial start

In progress

Actual: Jun 1, 2025

Phase 2a trial (NCT06685965) initiated and actively recruiting patients with insomnia associated with PTSD. Sublingual dexmedetomidine administration.

Why it matters: First clinical trial targeting PTSD-specific insomnia with sublingual dexmedetomidine. Actively recruiting as of April 2026 — strong execution signal. If successful, addresses major unmet need: ~70-91% of PTSD patients experience sleep disturbance.

RE01 (Sublingual DMT + Harmine)

Phase I

Sublingual formulation combining DMT (N,N-dimethyltryptamine) with harmine (MAO-A inhibitor) for controlled psychedelic experience without IV administration. Targets cocaine and stimulant use disorder. Phase 1 complete with safety and PK data from two trials in healthy volunteers.

Forecast

Phase II started - Likely: Q1 2027

Phase 1 studies NCT04716335 and NCT05829603 are complete, with peer-reviewed DMT/harmine formulation data published. Reconnect still lists RE01 for cocaine and stimulant use disorder, and a March 2026 company release highlighted RE01 as a controllable, scalable psychedelic architecture.

Milestones

Trial start

Completed

Actual: Jun 1, 2021

First Phase 1 trial (NCT04716335) initiated: randomized, double-blind, placebo-controlled study of sublingual DMT+harmine in healthy volunteers to establish safety, tolerability, and pharmacokinetic profile.

Why it matters: First clinical evaluation of a sublingual DMT+harmine combination. Sublingual route avoids the intensity and unpredictability of IV DMT while maintaining oral bioavailability via MAO-A inhibition — a significant formulation innovation.

data-readout

Completed

Actual: Jan 1, 2023

Phase 1 data published in Frontiers in Pharmacology and International Journal of Neuropsychopharmacology (IJNP). Two additional publications in Biomedicine & Pharmacotherapy. Four total peer-reviewed papers supporting RE01 safety/PK profile.

Why it matters: Four peer-reviewed publications from Phase 1 provide strong evidence base and scientific credibility. Published PK data supports sublingual route as viable alternative to IV DMT with controlled pharmacokinetics.

Trial start

Completed

Actual: Jun 1, 2023

Second Phase 1 trial (NCT05829603) initiated for sublingual DMT+harmine, building on first study safety data.

Why it matters: Follow-up Phase 1 expands safety database and refines dosing for Phase 2 design.

RE02 (Sublingual 5-MeO-DMT)

Phase I

RE02 is Reconnect's patented, precision-formulated sublingual 5-MeO-DMT / 5-HT1A-focused anxiolytic programme for treatment-resistant generalized anxiety disorder. ClinicalTrials.gov lists the Phase 1 registry NCT05979727 as terminated after 4 participants, while the current Reconnect pipeline continues to list RE02 with Phase 2a in GAD as the next-step focus.

Anxiety Disorders

Primary: Switzerland (Swissmedic)
Phase IActive

Forecast

Phase II started - Likely: Q2 2027

The Phase 1 RE02 registry remains listed as terminated after 4 participants. Reconnect's current pipeline still describes RE02 as a rapid-acting, non-addictive anxiolytic for treatment-resistant GAD, so the next action is company clarification of Phase 1 outcome and Phase 2a timing.

Milestones

Trial start

Completed

Actual: Jan 1, 2024

Phase 1 trial (NCT05979727) of sublingual 5-MeO-DMT initiated for treatment-resistant generalized anxiety disorder.

Why it matters: First clinical trial of sublingual 5-MeO-DMT formulation. 5-MeO-DMT has shorter duration (~30 min) than psilocybin or DMT, potentially enabling use in standard clinical settings. GAD represents a large underserved market.
