Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this trial is to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GRT7041 in healthy male and female (Women of non-childbearing potential) participants.

The trial duration will be up to approximately 6 weeks for participants in Part 1 (Single ascending dose \[SAD\]), except for participants taking part in the food effect cohort SAD3 where the trial duration will be up to approximately 8 weeks. The trial duration will be up to approximately 7 weeks in Part 2 (Multiple ascending dose \[MAD\]), and the Treatment Period will be up to 14 days (for Part 2).

The trial will include a Screening Visit, an in-house stay period and Follow-up (FU) Visit/End-of-Trial (EoT) Visit.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The trial will consist of two parts:

* Part 1: SAD with up to five cohorts SAD1 to SAD5 (n = 40). To be conducted in adult males and women of non-childbearing potential (WONCBP).
* Part 2: MAD with up to three cohorts, MAD1 to MAD3 (n = 30) dosed once daily (QD) for a period of 14 days. To be conducted in adult males only.

The trial design also evaluate the potential interaction of GRT7041 with a CYP3A4 index substrate that will be assessed separately in all cohorts in Part 2 (MAD) of the trial.

Dosing in Parts 1 and 2 will be conducted under fasted conditions, except for the SAD3 cohort in Part 1 (SAD), where participants will also receive a standardized breakfast (SAD3b treatment) to assess the effect of food.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. The participant must be able to give signed informed consent, including compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
2. Participants must sign the ICF before any trial-related assessments.

Exclusion Criteria

1. History of any of the following: cardiac impairment, renal impairment, pancreatitis, coagulation abnormalities.
2. Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk for treatment complications/ participation in the trial unsafe.
3. Any disease or conditions known to interfere with the absorption, distribution, metabolism, or excretion of the IMP.
4. Evidence or medical history of clinically significant and relevant psychiatric issues as assessed by the Investigator.
5. Confirmed or suspected history of clinically relevant drug allergy.
6. Major surgical procedure, within 30 days prior to ICF signing, or anticipation of need for a major surgical procedure during the trial.
7. Blood loss of 500 mL or more (eg, owing to blood donation) within 90 days before Screening Visit.
8. The participant has used any medication, including herbal remedies or over-the-counter medication within 2 weeks (or 5 half-lives, whichever is longer) before the start of the trial intervention or anticipated use during the trial, unless, in the opinion of the Investigator and Sponsor, the medication will not interfere with the trial.
9. The participant is enrolled in another clinical trial unless it is an observational (non-interventional) clinical trial or during the follow-up period of an interventional trial) or has received an IMP in another clinical trial within 30 days before Day 1 or within 5 times the elimination half-life of the IMP, whichever is longer.
10. Reluctance to comply with contraception requirements.
11. Evidence or history of alcohol or drug abuse including positive or missing alcohol breath test or drugs of abuse test(s).
