Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 74 participants

Brief 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.

Eligibility Criteria

Inclusion Criteria

1. Willing and able to give written informed consent for participation in the study.

2. Part I and IIa: Healthy male or female subject aged 18-50 years inclusive. Part IIb: Healthy male or female subject aged ≥65 years inclusive.

3. Body Mass Index (BMI) ≥ 18.0 and ≤ 30.0 kg/m2.

4. Clinically normal medical history, physical findings, vital signs, ECG and laboratory values at the time of screening, as judged by the Investigator.

5. WOCBP must practice abstinence (only allowed when this is the preferred and usual lifestyle of the subject) or must agree to use a highly effective method of contraception with a failure rate of < 1% to prevent pregnancy (combined [oestrogen and progestogen containing] hormonal contraception associated with inhibition of ovulation [oral, intravaginal, transdermal], progestogen-only hormonal contraception associated with inhibition of ovulation [oral, injectable, implantable], intrauterine device [IUD] or intrauterine hormone-releasing system [IUS]) from at least 4 weeks prior to dose to 4 weeks after last dose. 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
