INDV-2000 First in Human

A Phase I, Double-blind, Placebo-controlled, Randomized, Single Ascending Dose Study to Assess the Safety, Tolerability and Pharmacokinetics of INDV-2000 (C4X_3256) Under Fasting and Fed Conditions in Healthy Volunteers

This study is a single ascending dose (SAD) study conducted to identify the maximum tolerated dose (MTD) of INDV-2000. After completion of the SAD portion of the study and acceptable safety evaluation, a food-interaction, single-dose study under fed and fasted conditions will be conducted.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Treatment-emergent Adverse Events (TEAEs)	An adverse event (AE) was considered related to study drug if it could not reasonably be explained by other factors. A serious AE is any event that met any of the following criteria: Death; Life-threatening; In-patient hospitalization or prolongation of existing hospitalization; Persistent or significant disability/incapacity; Congenital anomaly/birth defect; Other important medical event that may have jeopardized the participant or required an intervention to prevent an above outcome. A severe AE describes the intensity of an AE, defined as causing marked limitation in activity; medical intervention or therapy or hospitalization required. For vital sign and laboratory abnormalities assessed as AEs, intensity was graded in accordance with the Food and Drug Administration Guidance for Industry: Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials, where Grade 3 = serious and Grade 4 = potentially life-threatening.	From first dose of study drug to end of study participation for each cohort; 11 days in Part 1 and 7 days in Part II, Period 1 (fasted conditions) and 10 days in Part II, Period 2 (fed conditions).

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Clinically Significant Laboratory Findings	The investigator assessed abnormal laboratory values to determine clinical significance.	From first dose of study drug to end of study participation for each cohort; 11 days in Part I and 7 days in Part II, Period 1 (fasted conditions) and 10 days in Part II, Period 2 (fed conditions).
Number of Participants With Clinically Significant Changes in Vital Signs	The investigator assessed changes in vital signs (including including blood pressure, respiratory rate, heart rate and temperature) to determine clinical significance.	From first dose of study drug to end of study participation for each cohort; 11 days in Part 1 and 7 days in Part II, Period 1 (fasted conditions) and 10 days in Part II, Period 2 (fed conditions).
Number of Participants With Clinically Significant Electrocardiogram (ECG) Findings	The investigator assessed abnormal ECG values to determine clinical significance.	From first dose of study drug to end of study participation for each cohort; 11 days in Part I and 7 days in Part II, Period 1 (fasted conditions) and 10 days in Part II, Period 2 (fed conditions).
Number of Participants With Clinically Significant Physical Examination Findings	Any clinically significant abnormalities observed during physical examination, including changes from baseline, were recorded as adverse events on the adverse event (AE) case report form (CRF) and are reported in the adverse events section of results below.
