Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
For Part A, healthy volunteers will receive a single inhaled dose of GDC-4379 or placebo. The starting dose will be 1 mg inhaled. A total of 6 dose cohorts are planned: Cohort A, B, C, D, H and I. The dose will be increased by approximately 2- to 3-fold (i.e., half-log or less) increments for each successive cohort. Actual doses may be adjusted depending on the outcome of preceding cohorts. Doses will be escalated based on safety, tolerability, and available PK data.

For Part B, healthy volunteers will receive an inhaled dose of GDC-4379 or placebo once or twice daily for a total of 14 days. A total of 4 dose cohorts are planned: Cohort E, F, Q and L. The dose will be increased by approximately 2- to 3-fold (i.e., half-log or less) increments for each successive cohort. Actual doses may be adjusted depending on the outcome of preceding cohorts. Doses will be escalated based on safety, tolerability, and available PK data. Daily dose will not exceed those evaluated in Part A.

For Part C, patients with mild asthma will receive an inhaled dose of GDC-4379 or placebo once or twice daily for 14 days. A total of 3 dose cohorts are planned: Cohort M, S, and either P or T. The final dose cohort (P or T) will be determined after the completion of Part B Cohort L. Doses will be escalated based on safety, tolerability, and available PK/PD data. Dose and duration will not exceed those evaluated in Part B.

For parts A, B and C all dosing will be done in clinic under the supervision of qualified medical staff.

A Safety Monitoring committee that will include at minimum the Medical Monitor, a drug safety scientist, and a biostatistician from the Sponsor; and will be responsible for dose-escalation decisions, with consent from the investigator.

NOTE: There have been several protocol amendments and study design iterations throughout the study, which resulted in cohorts G, J, K, N, O, R (each with varying doses) being eliminated from the study. These cohorts were never enrolled. To avoid potential confusion, any newly added cohorts were assigned the next available letter in the alphabet, rather than re-assigning a previously used letter from an eliminated cohort.

Outcomes
Primary outcome [1] 318977 0
The primary objective of this study is to characterize the safety profile associated with GDC-4379. This will be measured through the incidence and the severity of any adverse events, and change from baseline in vital signs, physical exam, laboratory test results, ECG, or spirometry. As a first-in-human study, the risks at this time are unknown. All adverse events (patient or investigator reported) will be classified using MedDRA coding system and the WHO Toxicity Grading Scale.
Timepoint [1] 318977 0
Adverse events will be reported after any occurrence after the first dose. Vital signs will be collected at each study visit for part A (visit days 1 through 15). For part B and C they will be collected on visit days (1-17, 21, 28, 35 and 42).
Secondary outcome [1] 366559 0
To characterize the PK profile of GDC-4379, Plasma concentrations of GDC-4379 will be assessed and pharmacokinetic parameters such as through AUC, tmax, Cmax, and half-life will be calculated.
Timepoint [1] 366559 0
To characterize the PK profile of GDC 4379 16 plasma samples will be assessed for GDC-0214 concentrations during the course of the SAD in order to sufficiently characterize PK parameters such as Tmax, Cmax,t1/2, and AUC. Individual PK parameters will not be assessed at specific time points since they require the totality of the data. PK will be collected on Day 1 (pre-dose, (5 min, 15 min and 30 min post-dose and 1, 2, 4, 8, and 12 hours post-dose) ). On Day 2 (24h and 36h post-dose). On Day 3 (48hr post-dose). On Day 4 (72h post-dose) and anytime during visit days 6, 10 and 15.
