Description of intervention(s) / exposure
Treatment: Drugs - Xeruborbactam Oral Prodrug
Treatment: Drugs - Ceftibuten
Treatment: Drugs - Xeruborbactam Oral Prodrug Placebo
Treatment: Drugs - Ceftibuten Placebo

Experimental: Single Dose Drug-Drug-Interaction Crossover & Multiple Dose Cohorts - During the DDI crossover part of the study, 24 subjects will be enrolled into 3 cohorts of 8 subjects each, Cohorts 1, 2, & 3 respectively.
All subjects in Cohorts 1, 2, and 3 will receive a single dose of xeruborbactam oral prodrug on Day 1. On Day 6, they will receive a single dose of ceftibuten. On Day 9 they will receive a single combined dose of xeruborbactam oral prodrug and ceftibuten.
During the MAD part of the study, 48 subjects will be enrolled into 3 cohorts of 16 subjects each, Cohorts 4, 5, & 6 respectively.
All subjects in Cohorts 4, 5, and 6 will receive either a combined dose of xeruborbactam oral prodrug and ceftibuten, active ceftibuten, or active xeruborbactam oral prodrug.
Cohort 4 & 5 will be dosed BID on Days 1 through 9, with last and final dose on the morning of Day 10.
Cohort 6 will be dosed BID on Day 1, and then QD on Days 2 through 10 with last dose on the morning of Day 10.
All subjects will be followed for safety and PK data collection.

Placebo Comparator: Placebo Comparator to maintain the blind - During the multiple-dose portion of the study, Xeruborbactam Oral Prodrug Placebo and Ceftibuten placebo will be used to maintain the blind. In Cohorts 4, 5, and 6, ten (10) subjects in each cohort will receive a combined dose of xeruborbactam oral prodrug and ceftibuten. Three (3) subjects in each cohort will receive active ceftibuten capsules with xeruborbactam oral prodrug placebo capsules. Three (3) subjects in each cohort will receive active xeruborbactam oral prodrug capsules with ceftibuten placebo capsules.

Eligibility
Key inclusion criteria
Participants will be eligible to be included in the study only if all of the following
criteria apply:

Age

1. Participant must be a healthy adult male or female, 18 to 55 years of age (inclusive)
at the time of screening.

Type of Participant and Disease Characteristics

2. Participants who are overtly medically healthy with clinically insignificant screening
results (eg, laboratory profiles, medical histories, ECGs, physical examination) as
assessed by the investigator, sub-investigator, or medical officer.

Weight

3. Body mass index (BMI) = 18.5 and = 29.9 (kg/m2) and weight between 55.0 and 100.0 kg
(inclusive). Note: BMI = kg/m2 where kg is a weight in kilograms and m2 is a height in
meters squared.

Sex and Contraceptive/Barrier Requirements

4. Contraceptive use by men and women should be consistent with local regulations
regarding the methods of contraception for those participating in clinical studies.

Male participants:

If male, agree to be sexually abstinent or agree to use 2 approved methods of
contraception (refer to inclusion criterion #5) when engaging in sexual activity from
study check-in through 30 days following the last administration of the study drug,
and to not donate sperm during this same period of time. If the sexual partner is
surgically sterile, contraception is not necessary.

5. Female participants:

Females of childbearing potential must either be sexually abstinent for 14 days prior
to Day 1 and agree to remain so through 30 days following the last administration of
the study drug, OR have been using (or agree to use) 2 of the following acceptable
methods of birth control for the times specified:

1. Intra-uterine device (IUD) in place for at least 3 months prior to Day 1 through
30 days following the final dosing of the study drug

2. Barrier method (condom or diaphragm) for at least 14 days prior to Day 1 through
30 days following the final dosing of the study drug

3. Stable hormonal contraceptive for at least 3 months prior to Day 1 and barrier
method (condom or diaphragm) for at least 14 days prior to Day 1 through 30 days
following final dosing of the study drug

4. Surgical sterilization (vasectomy) of partner at least 6 months prior to Day 1

Informed Consent

Form (Section 10.1.3) that includes compliance with the requirements and restrictions
listed in the informed consent form (ICF) and in this protocol.
