2. Subjects who signed informed consent.
3. Male subjects ≥18 and ≤55 years of age; female subjects ≥18 and ≤55 years of age of nonchildbearing potential defined as follows:

   * Female subjects 50 years of age or older, in menopause for 24 con-secutive months and not receiving any hormone replacement therapy within 24 months prior to inclusion into the study

6. Healthy subjects had to be in a good health in the opinion of the study phy-sician, as determined by medical history, ECG, vital signs, physical examina-tion, and clinical laboratory tests.
7. Having had no febrile or infectious illness for at least 14 days prior to dos-ing.
8. The subject was available to complete the study.
9. The subject was complying with the restrictions and requirements of the protocol and, in the opinion of the study physician, was able to complete the study.

Exclusion Criteria:

1. Unwilling or unable to give informed consent.
2. As a result of the medical screening process, the study physician considered the subject unfit for the study.
3. Pregnant or lactating women or men with female partners who are lactating or are pregnant.
4. Known or suspected history of hypersensitivity to rifabutin or excipients or to drugs of a similar chemical class including rifampicin, rifapentine, rifaximin; history of allergic reactions leading to hospitalisation or any other allergic con-ditions (including drug allergies, asthma, eczema, anaphylactic reactions but excluding untreated, asymptomatic, seasonal allergies) which the Investigator considers may affect the safety of the subject and/or outcome of the study.
5. History of antibiotic associated diarrhoea within the last year.
6. Volunteers with ECG abnormalities (history, or evidence of second-degree heart block of Mobitz type II, third degree heart block, or any abnormality con-sidered relevant by the Investigator), QTcF \> 450 ms, PR \> 200 ms, or QRS duration \> 110 ms.
7. Supine systolic blood pressure \> 140 mmHg or \< 90 mmHg or diastolic blood pressure \> 90 mmHg or \< 50 mmHg at Screening or Day 1 prior to dos-ing (any abnormal blood pressure results may be repeated once and if the re-peat result is within the normal range, it is not considered to have met the ex-clusion criterion). Pulse rate \> 90 or \< 50 beats per minute at Screening or Day 1 prior to dosing.
8. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and creatinine, above the ULN at Screening. Any abnor-mal value of these parameters may be repeated during screening period and if the repeat result is within the laboratory reference range, it is not considered to have met the exclusion criterion.
9. Screening values other than AST, ALT, ALP, creatinine, for haematology, biochemistry, or urinalysis must not exceed the reference range. Minor devia-tions from normal are allowed, if they are not clinically significant.
10. Leucocytes or neutrophils or lymphocytes below the lower limit of the ref-erence range.

11 History of symptomatic, chronic or recurrent infection (e.g. nausea, vomit-ing, diarrhoea, infection with fever) or any viral (including symptomatic herpes zoster), bacterial (including upper respiratory infection), fungal (non-cutaneous) or parasitic infection within 30 days prior to admission to the clini-cal unit.

12. A positive pre-study serology test for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies or human immunodeficiency virus (HIV)-1 and/or 2 antibodies.

13. Positive Coronavirus (SARS-CoV-2) rapid test and PCR (upon Check-in on Day -1) 14. A positive pre-study drug/alcohol screen. 15. History of epilepsy, other neurological disorders, or neuropsychiatric con-ditions.

21. Volunteers who have participated in a clinical study involving administra-tion of an investigational drug (new chemical entity) within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (which-ever is longer).

22. Volunteers who consume more than 21 units of alcohol per week or who have a significant history of alcoholism or drug/chemical abuse (one unit of alcohol equals ½ pint \[285 mL\] of beer or lager, one glass \[125 mL\] of wine, or 30 mL of 40% of alcohol by volume distilled spirits).

Contraindications related to midazolam: Hypersensitivity to the active sub-stance(s) or to any of the excipients, Severe hepatic impairment, Severe res-piratory failure or acute respiratory depression, Myasthenia gravis, Sleep ap-nea, Anatomical respiratory impairment or lung diseases. Note: as per Midazo-lam smpc "Pharmacokinetic interactions with CYP3A4 inhibitors or inducers are more pronounced for oral as compared to oromucosal or parenteral midazo-lam as CYP3A4 enzymes are also present in the upper gastrointestinal tract. Hence, a careful monitoring of the clinical effects and vital signs is recom-mended during the use of midazolam with a CYP3A4 inhibitor even after a single dose".
