Brief Summary

This trial is divided in 3 parts: FIH-SAD (Single Ascending Doses), FIH-MAD (Multiple Ascending Doses) and FIH-FE (Food effects). FIH-SAD will start first. The start of FIH-MAD will await the results of at least three cohorts from the FIHSAD study before initiated. The starting dose of the FIH-MAD will have been shown to be well tolerated and one dose level lower than the highest dose for which safety, tolerability and pharmacokinetic (PK) data are available. FIH-FE will be the last to start after the completion of FIH-SAD and conducted in parallel with parts of FIH-MAD.

Conditions

Safety, Tolerability, Pharmacokinetics of AEF0217

Outcome Measures

Primary Outcomes (4)

• Incidence of treatment-emergent AEs and SAEs as assessed by vital signs

  Evaluation by grade intensity and by evaluating changes from the baseline in vital signs Treatment-emergent potentially clinically significant abnormalities (PSCAs) in vital signs, ECG and safety laboratory parameters from Day 1 to EOS. Psychopathological tests: Profile of Mood States 2nd edition questionnaire (POMS-2), Hospital Anxiety and Depression rating scale (HADS), Addiction Research Center Inventory 49 checklist (ARCI-49), Columbia-Suicide Severity Rating Scale (C-SSRS)

  168 hours from dosing

• Incidence of treatment-emergent AEs and SAEs as assessed by ECGs

  Evaluation by grade intensity and by evaluating changes from the baseline in ECGs

  168 hours from dosing

• Incidence of treatment-emergent AEs and SAEs as assessed by clinical laboratory values

  Evaluation by grade intensity and by evaluating changes from the baseline in clinical laboratory values from blood and urine samples.

  168 hours from dosing

• Incidence of treatment-emergent AEs and SAEs as assessed by psychometric tests

  Evaluation by grade intensity and by evaluating changes from the baseline in psychometric tests (Bond and Lader VAS, ARCI, POMS) and C-SSRS test.

  36 hours from dosing

Study Arms (3)

PART I: SINGLE ASCENDING DOSE (FIH-SAD)

EXPERIMENTAL

Prospective, monocenter, double-blind, randomized, placebo-controlled, subsequent-group, Phase I investigation to assess the safety, tolerability and pharmacokinetics of AEF0217 administered orally in single ascending doses.

Drug: AEF0217; Drug: Placebo

PART II: MULTIPLE ASCENDING DOSES (FIH-MAD)

EXPERIMENTAL

Prospective, monocenter, double-blind, randomized, placebo-controlled, subsequent-groups, Phase I investigation to assess the safety, tolerability and pharmacokinetics of AEF0217 administered orally in multiple ascending doses.

Drug: AEF0217; Drug: Placebo

PART III: FOOD EFFECT (FIH-FE)

EXPERIMENTAL

Prospective, open-label single dose, two-condition (fed versus fasting), two sequences, crossover phase I investigation to assess the effects of food on the bioavailability of AEF0217.

Drug: AEF0217

Interventions

AEF0217 DRUG

PART I: A total of 32 healthy male and female subjects will be randomized into four consecutive single ascending dose cohorts of 8 subjects. The study will have 4 different doses of AEF0217 (0.2, 0.6, 2 \& 6 mg) and 1 dose of matching placebo. A given subject can be randomized only in one dose level cohort. PART II: A total of 24 healthy subjects will be randomized in three consecutive multiple ascending dose cohorts of 8 subjects. The study will have 3 different doses of AEF0217 (0.6, 2 \& 6 mg) and 1 dose of matching placebo. Doses could be modified following the results of FIH-SAD. A given subject can be randomized only in one dose level cohort. PART III: A total of 12 healthy male subjects will be randomly assigned to one of two sequences in the crossover study part. All subjects will receive the same dose of AEF0117 which will be determined following the results of the FIH-SAD.

Also known as: 3ß-benzyloxy-17α-methyl-pregn-5-en-20-one

PART II: A total of 24 healthy subjects will be randomized in three consecutive multiple ascending dose cohorts of 8 subjects. The study will have 3 different doses of AEF0217 (0.6, 2 \& 6 mg) and 1 dose of matching placebo. Doses could be modified following the results of FIH-SAD. A given subject can be randomized only in one dose level cohort.

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Healthy male subjects: As the effect of the study drug on sperm is still unknown, male subjects should refrain from donating sperm or plan a pregnancy with their partner throughout the study and until 90 days after the trial and must report immediately to the study doctor if its partner becomes pregnant during the trial and during 90 days after the trial. The male subject will have to use double-barrier contraceptive methods: male condoms and spermicide.
• Healthy female subjects of non-child-bearing potential: females may be accepted if they are documented to be surgically sterile i.e., hysterectomy, tubal ligation or post-menopausal with a negative pregnancy test (Not applicable for FIH-FE part III as it includes male only)
• Age ≥ 18 and ≤ 55 years.
• Weight ≥ 50 kg and ≤ 100 kg.
• Body mass index (BMI) ≥ 18 and ≤ 30.
• Negative serum pregnancy test (women only)
• Non-smoking.
• No history of or ongoing clinically relevant diseases or conditions.
• No clinically relevant findings in physical examination, vital signs (blood pressure, heart rate and body temperature), ECG and safety laboratory parameters that should be within normal ranges or considered as non-clinically relevant by the investigator.
• Negative covid19 PCR test within 72h before admission
• Able/willing to accept restrictions regarding diet, physical exercise, and consumption of alcohol and/or xanthine containing items when out of CRU.
• Able to read Spanish and adhere to study requirements.
• Not under any administrative or legal supervision.

• Lifetime history of deliberate self-harm due to suicidal ideation or suicidal ideation prior to study drug administration, as assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS).
• Clinically relevant cognitive impairment preventing the administration of the psychometric tests
• Any other clinically relevant disease or condition that in the judgment of the investigator might interfere with the subject's ability to comply with study procedures or requirements and/or bias the interpretation of the study results and/or jeopardize the subject's safety.
• Ongoing gastrointestinal diseases or history of gastrointestinal surgery affecting absorption
• Subjects with a clinically significant disease within one month prior to study drug administration.
