12 Medication assisted treatment considered best practice treatment for opioid use disorder

Large evidence-base for efficacy Important unmet medical needs

• Standard of care with daily buprenorphine or • Limited adherence to treatment methadone medications ‒ Poor treatment retention with continued illicit opioid use / “use on top” • Demonstrated effective in treating opioid ‒ Extensive misuse and diversion dependence • Safety issues ‒ Suppresses withdrawal and reduces cravings ‒ Overdoses ‒ Decreases illicit drug use ‒ Cardiac events (methadone) ‒ Reduces risky behavior, spreading of blood-borne disease and mortality • Need for daily, frequently supervised, dosing • On the World Health Organization’s Essential ‒ Inconvenient, stigma, and reduced quality of life Medicines List ‒ Burdens to the healthcare and criminal justice systems

No significant innovation in opioid use disorder treatment for the past 20 years

Study design Key Primary and Secondary Outcomes

• 24-week, double-blind, double-dummy, • Primary Endpoint randomized, active-controlled Phase 3 study ‒ EMA: Negative Urines with NI margin of -11% ‒ Treatment-seeking patients with moderate to severe ‒ FDA: Response Rate* with NI margin of -10% opioid use disorder, not currently on medication assisted treatment (MAT) • Key Secondary Endpoint: ‒ Assessed from treatment initiation to maintenance ‒ EMA: Cumulative Distribution Function (CDF) ‒ Non-inferiority and superiority objectives of urines negative for illicit opioids from Week 5 to 25. (Sampling Weeks) ‒ CAM2038 vs. sublingual buprenorphine/naloxone BPN/NX – “Standard of Care” ‒ FDA: CDF of negative urines plus self-reports negative for illicit opioids from Week 5 to 25 (Sampling Weeks). ‒ Multiple additional secondary and explorative endpoints: retention; craving, morning cravings, withdrawal (SOWS and COWS)

* Responder defined as displaying negative urine samples, including self-reports, for; treatment week 12 and month 6, at least 2 of treatment weeks 9, 10 and 11 and 12, and at least 5 of the 6 samples obtained during treatment weeks 12 through 24.

21 CAM2038 demonstrated non-inferior and superior efficacy across treatment phases versus daily SL BPN/NX

Robust efficacy versus “Standard of Care”

• Met both FDA and EMA primary endpoints • Statistical superiority for the key secondary endpoint of CDF for negative urines • Efficacy throughout treatment phases ‒ From initiation to maintenance • CAM2038 safety profile comparable to daily sublingual buprenorphine/naloxone ‒ Fewer SAEs (3.2% vs. 6%) ‒ No drug overdoses vs 4 overdoses ‒ Good local tolerability; no severe AEs • MAA and NDA submissions mid-2017
