Inclusion Criteria:

1. Able and willing to provide written informed consent to participate in this study after reading the participant information sheet and Informed Consent Form (ICF) and having the opportunity to discuss the study with the Investigator or designee.

2. Healthy male or female subjects, 18-45 years of age, inclusive, at the time of signing the ICF.

3. Subjects must weigh at least 50 kg (110 pounds) but no more than 95 kg (209 pounds) and have a body mass index (BMI) 18.0 to 30.0 kg/m2 both inclusive at Screening and on Day -1.

4. Female subjects must not be lactating and must have a negative serum pregnancy test at screening and a negative urine pregnancy test within 24 hours before receiving the first dose of IMP.

5. Female subjects of childbearing potential and male subjects with a partner of childbearing potential must agree to use 2 effective methods of contraception (in female subjects, one method must be highly effective).

6. Male subjects must agree not to donate sperm and female subjects must agree not to donate ova until 3 months after the last dose of IMP.

7. In the Investigator's opinion, the subject can understand the nature of the study and any risks involved in participation and is willing to cooperate and comply with the protocol restrictions and requirements.

Exclusion Criteria:

1. Presence or history of any hepatobiliary disease at Screening, determined clinically significant by the Investigator after discussion with Sponsor's Responsible Physician. Current, or history of, clinically significant (in the opinion of the Investigator and Sponsor Responsible Physician) endocrine, respiratory, neurological, gastrointestinal, renal, cardiovascular disease, or history (within the last 2 years) of any clinically significant psychiatric/psychotic illness disorder (including anxiety, depression, and reactive depression).

2. Clinically relevant abnormal medical history, physical findings or laboratory values at Screening or Day -1 that could interfere with the objectives of the study or the safety of the subject, as judged by the Investigator.

3. Subject with a history of gastrointestinal surgery or disease known to affect absorption, metabolism, or excretion of the IMP (other than surgical history of appendectomy and hernia repair / herniorrhaphy / hernioplasty are permitted).

4. Subjects who have had major surgery within 3 months of Day 1.

5. Family history of long or short QT syndrome, hypokalemia, syncope, or Torsades de Pointes.

6. Clinically significant 12-lead ECG abnormalities, including subjects with QTcF of ≥450 msec at Screening or Day -1. A repeat assessment is allowed at each visit. If the repeat measurement is in range, the subject may be included.

7. Subjects with aspartate aminotransferase (AST), alanine aminotransferase (ALT), or bilirubin ≥1.5 × upper limit of normal reference range at Screening or Day -1. A repeat assessment is allowed at each visit. If the repeat measurement is in range, the subject may be included.

8. Blood pressure (supine) at Screening or Day -1 outside the range 90-145 mmHg (systolic) or 50-95 mmHg (diastolic); and resting heart rate (HR) outside the range of 45-100 bpm. A repeat assessment is allowed at each visit. If the repeat measurement is in range, the subject may be included.

9. Receipt of any prescribed or nonprescribed systemic or topical medication within 30 days (or, if relevant, 5 half-lives, whichever is longer) prior to the first dose of study drugs unless, in the opinion of the Investigator and Sponsor, the medication will not interfere with the study procedures or compromise subject safety.

1. Occasional use of paracetamol (acetaminophen) for mild analgesia is permitted.

2. Vitamins and herbal supplements are not permitted 14 days prior to dosing.

10. Presence or history of severe adverse reaction or allergy to any drug or excipient or other allergies that are of clinical significance to the study drugs.

11. Previously having received MT-7117.

12. History or presence of melanoma and/or lesions suspicious for melanoma at Screening.

a. Subjects with the presence of a skin lesion suspicious for dysplastic nevus or a history of histologically proven dysplastic nevus.

13. Subjects with a first-degree relative with a history of familial melanoma.

14. Subjects who have previously received afamelanotide or melanotan.

15. Subjects who test positive for hepatitis B surface antigen, hepatitis B core antibody, hepatitis C antibody, or human immunodeficiency virus (HIV) 1 and HIV 2 antibodies at Screening.

Subjects who have had coronavirus disease 2019 (COVID-19) in the 3 months prior to Screening; or suspected active COVID-19 infection, a positive COVID-19 test, contact with an individual with known COVID-19, or travel to an area with a high risk of COVID-19 infection within 14 days of Screening or Day 1.

1. Subjects who have received a COVID-19 vaccination within 14 days of Day 1. COVID-19 vaccination is not permitted during the study. Subjects may not take part in the study if they have started but not completed a COVID-19 vaccination course at the time of Screening or Day -1. Subjects who do not plan to complete the COVID-19 vaccination course will be allowed to participate in the study as long as at least 14 days have elapsed since the last vaccination.

2. Subjects who test positive for COVID-19 at Day -1.

3. Subjects currently suffering from clinically significant prolonged COVID symptoms.

17. Presence or history of drug abuse (as defined by Diagnostic and Statistical Manual of Mental Disorders [DSM-V] criteria), or a positive urine test for drugs of abuse at Screening or Day 1.

18. Presence or history (in the last 2 years) of alcohol abuse or excessive alcohol consumption, defined as subjects who regularly, or on average, drink more than 21 units (168 g) for males or 14 units (112 g) for females, of alcohol per week (1 unit is equivalent to 8 g of alcohol).
