New COPD drug safety checked in healthy volunteers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Willing and able to understand the information on the nature, the scope, and the relevance of the trial, and to provide voluntary, written informed consent to participate in the trial before any trial-related procedures. 2. Healthy male or female participant aged 18 to 55 years, inclusive. 3. Body mass index ≥ 19.0 and ≤ 33.0 kg/m2 at the time of the screening visit. 4. Medically healthy participant without abnormal clinically significant medical history, physical findings, vital signs, ECG and laboratory values at the time of the screening visit, as judged by the Investigator. 5. Non-smoker, or former smoker with \<10 pack years who stopped smoking (including e-cigarettes) at least 6 months before the screening visit. 6. Women of childbearing potential (WOCBP) must: 1. have a negative pregnancy test (blood) at the screening visit and (urine) Day 1. 2. agree to use, and be able to comply with, highly effective measures of contraceptive control (failure rate less than 1% per year when used consistently and correctly) without interruption, during trial participation and until 90 days after the last IMP intake. 3. agree to abstain from breast feeding during the trial participation and for 90 days after the last IP intake. Women defined as of non-childbearing potential are postmenopausal (no menses for at least 1 year without alternative medical cause \[follicle stimulating hormone, FSH, measurement in serum may be done as additional confirmation at Investigator's discretion\]) or surgically sterile women (tubal ligation, hysterectomy, or bilateral oophorectomy). Men must agree to use a condom during sexual intercourse with WOCBP during treatment and for 90 days after the last IP intake and should not donate sperm during this time. Exclusion Criteria: Participants must not enter the trial if any of the following exclusion criteria are fulfilled: 1. History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the participant at risk because of participation in the trial, or influence the results, or the participant's ability to participate in the trial. 2. Any clinically significant illness, medical/surgical procedure or trauma within 4 weeks of the (first) administration of IMP. 3. Presence or history of lung disease, e.g., asthma, chronic obstructive pulmonary disease. 4. Presence or history of significant gastrointestinal medical condition that could lead to abnormal absorption. 5. History of or active tuberculosis at the time of the screening visit based on participant anamnesis. Participants who have been living together with another person with active tuberculosis at any time over the past 10 years will also be excluded. 6. Clinically significant abnormality on 12-lead ECG at the screening visit or Day 1 pre-dose, including prolonged QTcF (\>450 msec men or \>470 msec women) or PR interval \>210 msec. 7. Abnormal renal function at the time of the screening visit: * serum creatinine \>upper limit of normal (ULN); and/or * estimated glomerular filtration rate \<60 mL/min according to the revised Lund-Malmö GFR estimating equation. 8. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>1.5 x ULN at the time of the screening visit. 9. Use of prescription or non-prescription medications or herbal remedies within 28 days prior to Day 1, or unable to refrain from prescription or non-prescription medications or herbal remedies during the trial, with the following exceptions: * hormone replacement therapy (HRT) * contraception * occasional use of paracetamol Note: other medications will be reviewed by the Medical Monitor and a participant may be included if both the Investigator and Medical Monitor agree that the medication will not interfere with the trial assessments or participant's safety. 10. Live vaccine within 28 days or any other vaccine within 14 days prior to Day 1 until 28 days after the final dose (with the exception of COVID-19 vaccine boosters). 11. Any positive result at the screening visit for serum hepatitis B surface antigen, hepatitis C antibodies and/or human immunodeficiency virus (HIV). 12. Positive screening result for drugs of abuse, cotinine or alcohol at the screening visit or on admission to the trial site prior to the (first) administration of the IMP. A positive urine cotinine test (≥200 ng/mL) at screening or at Day -1 will exclude the participant from trial participation. 13. History of alcohol abuse or excessive intake of alcohol, as judged by the Investigator. 14. Presence or history of drug abuse, as judged by the Investigator. 15. History of, or current use of anabolic steroids, as judged by the Investigator. 16. Excessive caffeine consumption defined by a daily intake of \> 5 cups (1 cup = approximately 240 mL) of coffee, or equal amount in other caffeine containing beverages, or unable to refrain from caffeine containing beverages, including energy drinks, during the trial, as judged by the Investigator. 17. Former smoker with \>10 pack years, or smoking (including use of e-cigarettes and vapes) within 6 months of the screening visit, or unable to refrain from smoking throughout the trial. 18. Use of nicotine replacement products within 2 weeks of the screening visit and unable to refrain from nicotine replacement products throughout the trial. 19. Participants who are pregnant, currently breastfeeding, or intend to become pregnant during the course of the trial. 20. Known hypersensitivity to macrolides or EP395 or any of the excipients (dicalcium phosphate, croscarmellose sodium, magnesium stearate, microcrystalline cellulose). 21. History of hypersensitivity to or contraindication (as indicated in the SmPC) to verapamil (Part A) or digoxin and/or midazolam (Part B). 22. Any clinically significant allergy, as judged by the Investigator. 23. Planned treatment or treatment with another investigational drug within 5 half-lives of said drug or 3 months prior to first IMP administration, whichever is longer. Participants consented and screened, but not dosed in previous Phase 1 trials are not excluded. 24. Employees of the Sponsor or employees or relatives of the Investigator. 25. Plasma donation within one month of screening or blood donation (or corresponding blood loss) during the last three months prior to the first IMP administration. 26. The Investigator considers the participant unlikely to comply with trial procedures, restrictions and requirements.
