Treatment: Drugs - SPR994
Treatment: Drugs - Placebo Oral Tablet
Treatment: Drugs - Orapenem®

Experimental: SPR994, FI, F2, F3, F4 Oral Tablets - SPR994 is active against multidrug-resistant Gram-negative and Gram-positive pathogens that cause serious and life-threatening infections, including extended spectrum beta-lactamase (ESBL) producers as well as strains resistant to levofloxacin and trimethoprim/sulfamethoxazole. SPR994 is administered in tablet form orally. Up to five different time released formulations of SPR994 will be studied in this protocol at 100 mg, 300 mg, 600 mg and 900 mg dosages.
SAD Cohorts: One dose (two for food effect cohort) MAD Cohorts: Twenty-seven (27) doses administered twice daily (BID) over a period of 14 days or forty doses administered three times daily (TID) over period of 14 days

Placebo Comparator: Placebo Oral Tablet - Placebo tablets (100, 300, and 600 mg) are pressed from a single placebo blend consisting of the same inactive ingredients; the active pharmaceutical ingredient (API) is replaced by Mannitol 200SD.
SAD Cohorts: One dose (two for food effect cohort) MAD Cohorts: Twenty-seven (27) doses administered BID over a period of 14 days or forty doses administered TID over a period of 14 days

Other: Optional Orapenem Open-Label Control - A single, optional, open-label, control cohort that may enroll, in which all 8 subjects receive Orapenem.
SAD Cohort: One dose under fasted conditions and one dose under fed conditions.


Treatment: Drugs: SPR994
SAD: Double-blind dosing will occur in all SAD Cohorts except for Cohort 12. In each cohort, six subjects will receive one of five different timed release formulations of SPR994 and 2 subjects will receive placebo. Subjects in SAD Cohorts 2, 3, 6, 16 and 17 will receive a single dose following a 10-h fast. Subjects in SAD Cohorts 1, 8-15 will receive one dose of SPR994 or placebo following a 10-h fast on Day 1 and a second dose following consumption of a standardized meal on Day 7. The dose escalation steps may be altered following review of the safety data of each cohort.
MAD: Double-blind dosing will occur in all MAD Cohorts. Subjects will receive multiple doses of an optimal timed release formulation of SPR994 in MAD Cohort 4 (300 mg) and Cohort 5 (600 mg) or placebo for 14 consecutive days at either BID or TID dosing beginning on Day 1.

Treatment: Drugs: Placebo Oral Tablet
Mannitol 200SD SAD: Two subjects in each cohort will receive matching placebo. MAD: Two participants in each cohort will receive matching placebo.

first study drug administration until 30 days after the final administration of study
drug.

- Participation in another investigational clinical trial within 30 days prior to Day 1;

Summary
Brief summary
This is a double-blind, placebo-controlled, ascending dose, multi-cohort trial. The study
will be conducted in 2 parts: a single ascending dose (SAD) part, followed by a multiple
ascending dose (MAD) part. In SAD, all subjects will receive 1 dose of SPR994 (100, 300, 600
or 900 mg) or placebo, except for subjects enrolled in food effect cohorts in which subjects
will receive one dose following a 10 hour fast and a second dose in the fed state following a
minimum 5 days washout period. There is a single, optional, open-label control cohort that
may enroll, in which all 8 subjects will receive Orapenem® (tebipenem pivoxil fine granules).
In MAD, subjects will receive multiple doses of SPR994 (300 or 600 mg) or placebo for 14
consecutive days at either BID or TID dosing. In both parts, cohorts will be exposed to
increasing doses of SPR994 with various extended release formulations.
