Clinical Trial Summary

this study will be a Phase 1, single-dose, two parallel cohorts, open-label, randomized study in healthy subjects with Cohort 1 as bioequivalence (BE) and food effect study and Cohort 2 as a drug-drug interaction (DDI) study.


Description:

Cohort 1 (BE) is a four-period, four-sequence, four-treatment crossover BE and food effect study of zoliflodacin granules for oral suspension manufactured by Dr. Reddy's (test product, ZoliDr) and those manufactured by Patheon (reference product, ZoliPa) as a 3 g oral dose under fasting and a [specific] fed condition. This cohort will comprise of approximately 32 subjects (8 healthy subjects per treatment sequence) in 4 x 4 BE treatment arms in fasted and [specific] fed conditions. Healthy subjects will be randomized into 4 parallel treatment sequences to receive sequential Treatments A, B, C, and D in William's Square design pattern where: - Treatment A is ZoliPa fasted - Treatment B is ZoliDr fasted - Treatment C is ZoliPa [specific] fed condition - Treatment D is ZoliDr [specific] fed condition Based on William's Square design, below treatment sequences will be followed: A-B-C-D B-A-D-C C-D-A-B D-C-B-A There will be 4 treatment periods, each with a single dose of the investigational medicinal products (IMP). The washout period between each IMP administration will be at least 72 hours. Food regimen: Subjects, who are in a treatment period in which they are [specific] fed, will be dosed 30 minutes after the start of food intake. The subjects are expected to consume the entire meal within 30 minutes prior to dosing. Cohort 2 (DDI): This is an open-label, 2-period, 2-treatment, fixed sequence crossover DDI study in healthy subjects. It will investigate PK of zoliflodacin (ZoliPa) in the absence and presence of itraconazole. Approximately 18 subjects will receive ZoliPa on Day 1 under fasting condition. After a washout of 72 hours after dosing of ZoliPa, on Day 4, subjects will receive a 400 mg loading dose of itraconazole followed by 200 mg of itraconazole once daily from Day 5-8. From Day 4 to Day 8, itraconazole will be administered immediately after a full meal. On Day 9, both itraconazole and zoliflodacin (ZoliPa) will be administered under fasting conditions at -1 hours and 0 hours, respectively. Itraconazole will then be administered with food at 24 hours (Day 10) and 48 hours (Day 11) after administration of zoliflodacin (ZoliPa).

Healthy subjects, defined as individuals who are free from clinically significant illness or disease as determined by their medical/surgical history, normal vital signs, normal physical examination, normal standard 12-lead electrocardiogram (ECG), and laboratory investigations. 4. At the Screening visit, supine vital signs must be within the following ranges: - Systolic blood pressure (SBP) between 90 and 139 mmHg - Diastolic blood pressure (DBP) between 60 and 89 mmHg - Pulse between 50 and 90 beats per minute (bpm) - Tympanic temperature between 35.0 and 37.5°C Note: These will be measured after resting for 10 min. 5. Able to understand and communicate in German/or native language of the site with the Investigator and research staff and to comply with the requirements of the entire study. Provision of written informed consent to participate in the study. 6. Female subjects, if: o Not of childbearing potential, e.g., have a documentation of irreversible surgical sterilization by hysterectomy and/or bilateral oophorectomy and/or bilateral salpingectomy and/or bilateral tubal ligation, at least 6 weeks before the Screening visit, amenorrhea for = 12 months and follicle stimulating hormone (FSH) in the post menopausal range according to local laboratory ranges. o Of childbearing potential (for inclusion in Cohort 1, BE Study only), the following conditions are to be met: i. Negative pregnancy test: If this test is positive, the subject will be excluded from the study. In the rare circumstance that a pregnancy is discovered after the subject received zoliflodacin, the IMP, every attempt must be made to follow her to term and the newborn(s) up to 2 years of age. ii. Not lactating iii. The female subject must agree to use, with their partner, an approved method of highly effective contraception in combination with a barrier method from at least 1 month before the Screening visit until 1 month after last dosing of IMP. Female subjects must agree not to attempt to become pregnant, must not donate ova from the Screening visit until at least 1 month after last dosing of IMP. The following are considered to be highly effective methods of birth control: 1. Hormonal contraception (i.e., combined oral contraceptives, injectable or implantable hormonal contraceptives 2. Hormonal or non-hormonal intrauterine device/system with a proven failure rate <1% 3. The subject's male partner has undergone confirmed effective surgical sterilization before the female subject entered the clinical study and he is the sole sexual partner of the female subject during the clinical study 4. True abstinence: When this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation symptothermal, post ovulation methods], declaration of abstinence for the duration of the study and withdrawal are not acceptable methods of contraception). Barrier methods of contraception include: 1. Condom (with or without spermicidal foam/gel/film/cream/ suppository but not use of fat/oil containing lubricants). 2. Occlusive cap (diaphragm or cervical/vault caps) with spermicidal gel/film/cream/suppository. 3. Other methods, if considered by the Investigator as reliable, will be accepted. 7. Male subjects who agree to use appropriate contraception methods to prevent pregnancy in their female partner(s) from the time of first dose until one month after last dose of IMP administration, i.e., condoms with or without spermicide. A male subject should be instructed that, unless his female partner(s) has had a tubal ligation, hysterectomy, or bilateral oophorectomy or is post-menopausal, his female partner(s) should use another form of contraception from the time of first dosing until one month after last dose of IMP administration - such other forms of contraception include an intrauterine device, condom, diaphragm with spermicide, oral contraceptive, injectable progesterone, or subdermal implant; male subjects who have been vasectomized at least 6 months before the first dose of IMP are exempt from the use of condom, and his female partner(s) do(es) not need any additional form of contraception. 8.
