A Study To Investigate The Safety, Tolerability And Pharmacokinetics (PK) Of RO7223280 Following Intravenous Administration In Healthy Participants

NCT ID: NCT04605718

Last Updated: 2023-04-18

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 124 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2020-12-07
• Study Completion Date: 2023-03-09

Brief Summary

The Study consists of 3 Parts: Part 1 (Single Ascending Dose/SAD), Part 2 (Multiple Ascending Dose/MAD), and Part 3 (Elderly). Part 1 will investigate the safety, tolerability and PK of single-ascending intravenous (IV) doses of RO7223280 in healthy participants. Part 2 will investigate the safety, tolerability and PK of multiple-ascending IV doses of RO7223280 in healthy participants. Part 2 will start after the initial completion of Part 1 (SAD). Progression from Part 1 to Part 2 will be based on a satisfactory review of all available safety, tolerability, and PK data by the Investigator and the Sponsor from Part 1. The starting dose for Part 2 will be administered as 1-hour IV infusion; as it has been established on the basis of all available safety, tolerability, and PK data in Part 1 (SAD). Part 3 will investigate the safety, tolerability and PK of a single IV dose of RO7223280 in healthy elderly participants. A single IV dose of RO7223280 administered over 1 hour was selected, within the range of previously explored doses in Part 1 (SAD).

Study Groups

Part 1 (SAD)

Due to mandatory sentinel dosing, participants will be divided into two groups: 2 participants will be dosed on one day (sentinel group with 1 on active treatment and 1 on placebo) and remaining participants of the dose cohort (randomized as 5 on active treatment and 1 on placebo) at the earliest 24 hours after the first dosing occasion.

Group Type: EXPERIMENTAL

RO7223280

Intervention Type: DRUG

For Part 1 (SAD) and Part 2 (MAD), RO7223280 will be administered by intravenous (IV) infusion at escalating doses from 10mg to 4800mg, as per the dosing schedules described above. These are putative doses and the maximum daily dose that must not be exceeded is 5000mg. For Part 3 (Elderly), RO7223280 will be administer as one single IV dose of 300 mg.

Part 2 (MAD)

In each dose cohort, a minimum of 4 participants and a maximum of 12 participants will receive either multiple IV doses of RO72232809 or placebo once-daily for 10 days (3:1 ratio of active:placebo treatment).

Eligibility Criteria

Inclusion Criteria

• Parts 1 (SAD) and 2 (MAD): 18 to 64 years of age, inclusive. Part 3 (Elderly): 65 years of age and older
• Healthy participants in Part 1 (SAD) and Part 2 (MAD). Health status is defined by absence of evidence of any active or chronic disease following a detailed medical and surgical history, a complete physical examination including vital signs, 12-lead ECG, hematology, blood chemistry, serology, coagulation, and urinalysis. Healthy participants in Part 3 (Elderly). Participants must be in reasonably good health as determined by the Investigator based on medical and surgical history, a complete physical examination including vital signs, 12-lead ECG, hematology,blood chemistry, serology, coagulation, and urinalysis. Participants with mild, chronic, stable disease (e.g., controlled hypertension, controlled diabetes mellitus) may be enrolled if deemed medically prudent by the Investigator.
• In Part 1 (SAD) and Part 2 (MAD) participants must weigh at least 50 kg and must have a body mass index (BMI) within the range of 18 to 32 kg/m^2 (inclusive). In Part 3 (Elderly), participants must weigh at least 50 kg with no restrictions regarding the BMI.
