Clinical Trial Summary

The purpose of the trial is to evaluate CUR-N399, a PI4KB inhibitor, in a first-in-human trial to evaluate the safety, tolerability and pharmacokinetics profile of single and multiple ascending doses in healthy adults. In the SAD part of the trial, single oral doses of CUR-N399 will be administered in 5 sequential cohorts. In all cohorts, safety and PK will be assessed before and after dose. Exploratory nasopharyngeal swab for assessment of airway infectants will be performed before dose and in the morning of Day 3. In SAD part Cohort 4: A urine sample will be taken from the first morning void on Day 1 and urine will be collected for potential quantification of CUR-N399 (and metabolites) during the first 24 hours post-dose. The MAD part of the trial will explore multiple ascending dosing of CUR-N399. The initial dose, dose escalation and dosing schedule will be based on emerging knowledge of safety, tolerability and PK of CUR-N399 observed in the SAD part of the trial. CUR-N399 will be administered in 3 sequential cohorts. An additional MAD cohort will evaluate CUR-N399 in older adults ≥65 years. All SAD and MAD cohorts will evaluate 8 subjects. Within each cohort, subjects will be randomised in a 3:1 ratio to receive CUR-N399 (n=6) or placebo (n=2) in a blinded fashion.

Female subjects must refrain from donating eggs from the date of dosing until 3 months after dosing with the IMP. Their male partner must agree to use a condom during the same time frame if he has not undergone vasectomy. Women of non-childbearing potential are defined as pre-menopausal females who are sterilised (tubal ligation or permanent bilateral occlusion of fallopian tubes); or females who have undergone hysterectomy or bilateral oophorectomy; or post-menopausal defined as 12 months of amenorrhea (in questionable cases a blood sample with detection of follicle stimulating hormone [FSH] 25-140 IE/L is confirmatory). Male subjects must be willing to use condom or be vasectomised or practice sexual abstinence to prevent pregnancy and drug exposure of a partner and refrain from donating sperm from the date of dosing until 3 months after dosing with the IMP. Their female partner of child-bearing potential must use contraceptive methods with a failure rate of < 1% to prevent pregnancy (see above). - Exclusion Criteria: 1.

Planned treatment or treatment with another investigational drug within 3 months prior to Day -1. Subjects consented and screened but not dosed in previous Phase I studies are not excluded. 13. Current smokers or users of nicotine products. Irregular use of nicotine (e.g. smoking, snuffing, chewing tobacco) less than three times per week is allowed before screening visit. 14. Positive screen for drugs of abuse or alcohol at screening or on admission to the unit prior to (first) administration of the IMP. 15. History or presence of alcohol abuse or excessive intake of alcohol, as judged by the Investigator. 16. Presence or history of drug abuse, as judged by the Investigator. 17.
