Phase 1 Safety, Tolerability and Pharmacokinetics (PK) Study of FP-025 in Healthy Volunteers

In the SAD part of the study the investigational drug will be administered once in a dose
escalation manner starting from 200 mg in Cohort 1 to 2000 mg in Cohort 6. The study drug
will be orally taken as capsules. In the MAD part of the study the investigational drug will
be administrated twice daily for 5 days depending on the half-life of FP-025, as determined
in the SAD part of the study. Study subjects will be randomized in a 1:3 ratio to either
placebo or FP-025 in every cohort of the SAD and MAD part of the study.

Inclusion Criteria:

- Males aged ≥18 and ≤55 years with a BMI ≥18 kg/m2 and ≤32 kg/m2.

- A resting pulse ≥50 bpm and ≤100 bpm at the Screening Visit.

- A resting systolic blood pressure of ≤140 mmHg and a resting diastolic blood pressure
of ≤90 mmHg at the Screening Visit.

- Baseline laboratory test values within reference ranges based on the blood and urine
samples taken at the Screening Visit. Out of normal ranges values (except for liver
parameters) may be accepted by the investigator, if not clinically significant.

- The subject is, in the opinion of the investigator, generally healthy based on
assessment of medical history, physical examination, vital signs, electrocardiogram
(ECG), and the results of the haematology, clinical chemistry, urinalysis, serology,
and other laboratory tests.

- Adequate contraception (double-barrier) will be applied during and until 3 months
after completion of the study.

- Signed Informed Consent prior to any study related procedures.

- Ability to communicate well with the investigator, in the local language, and to
understand and comply with the requirements of the study.

Exclusion Criteria:

- The subject has taken disallowed medication within 1 week prior to the first dose of
study product (or within 5 half-lives prior to inclusion for any medication ingested,
whichever is longer).

- The subject has a substance abuse-related disorder or has a significant history of
drug or alcohol abuse, defined as an alcohol intake greater than 21 units per week or
a history of drug abuse or a history of substance abuse deemed significant by the
investigator.

- The subject should avoid alcohol for at least 5 days before admission into the
clinic.

- The subject has taken any investigational products within 30 days prior to the first
dose of study product.

- The subject has a history of severe drug allergy or hypersensitivity or food allergy.

- The subject has a history or presence of any clinically significant immunological,
cardiovascular, respiratory, metabolic, renal, hepatic, gastrointestinal,
endocrinological (in particular diabetes or pre-diabetes), haematological,
dermatological, venereal, neurological, chronic infectious or psychiatric disease or
other major disorder.

- The subject has a history of cancer, other than basal cell or Stage 1 squamous cell
carcinoma of the skin, which has not been in remission for at least 5 years prior to
the first dose of study product.

- The subject has a history of abdominal surgery (excluding laparoscopic
cholecystectomy or uncomplicated appendectomy) or thoracic or non-peripheral vascular
surgery within 6 months prior to the first dose of study product.

- The subject has any concurrent illness that may affect the particular target or
absorption, distribution, and elimination of the study product.

- The subject has had a clinically significant illness within 4 weeks prior to the
first dose of study product.

- The subject has had surgery or trauma with significant blood loss within the last 3
months prior to the first dose of study product.

- The subject has donated blood within 3 months prior to the first dose of study
product.

- The subject has tested positive for human immunodeficiency virus (HIV), hepatitis B
surface antigen (HBsAg), or hepatitis C virus antibody (anti-HCV).

- The subject is a current smoker or uses other nicotine containing products.
Ex-smokers must have ceased smoking at least 6 months prior to the first dose of
study product (+ <10 pack years).

- The subject should avoid glutamate rich food before admission and during the study.

- The subject has tested positive after the Screening Visit or at the Safety Baseline
Visit for drugs of abuse (opiates, methadone, cocaine, amphetamines (including
ecstasy), barbiturates, benzodiazepines and cannabinoids).

- The subject's corrected QT interval (QTc) (Bazett's or Fridericia's correction) is
>450 ms as read on the printout of the ECG produced by the ECG equipment and
evaluated by the investigator at the Screening Visit. An out-of-range or abnormal ECG
may be repeated. In total, 3 ECGs should be recorded consecutively and the
investigator must evaluate the triplicate ECG. If the subject's QTc is >450 ms on at
least 2 ECGs, the subject must be excluded.

- The subject exercises extensively (e.g. marathon, triathlon or other similar high
energetic sports). In general, subjects should refrain from sporting for at least 4
days before participation to the study.

- The subject is, in the opinion of the investigator, unlikely to comply with the
clinical study protocol or is unsuitable for any other reason.

- A history of psychiatric diseases, i.e depression and/or anxiety related illness.

- Serum creatinine, aspartate aminotransferase (AST) or alanine aminotransferase (ALT)
above the upper limit of normal (ULN) at screening.

- Hemoglobin, white blood cells (WBC) or platelet count below the lower limit of normal
(LLN) at screening.

- Other laboratory results which are clinically significant abnormal at screening.

- Legal incapacity or limited legal capacity at screening.

- Employees of the investigator or study centre, as well as first grade family members
of the employees or the investigator.
