Syneos Health40 enrolled

Overview

This is Phase I first-in-human trial evaluating the safety, tolerability, immunogenicity, and pharmacogenomics of LQ036 via inhalation and IV infusion. The study will be divided into 4 parts: Single Ascending Dose, Multiple Ascending Dose, and Intra Venous with a target of 88 healthy volunteers and 30 patients with mild Asthma.

This study will be a Multicenter, phase Ia/Ib, randomized, double-blind, placebo controlled, Single Ascending Dose(SAD)/ Multiple Ascending Dose (MAD) study of dose escalation cohorts evaluating the safety, tolerability, immunogenicity, and PK of LQ036 after administration via inhalation and intravenous (IV) infusion in healthy subjects and patients with mild Asthma. The study will be divided into 4 parts: The four parts will be completed sequentially or with partial overlapping. Part A - SAD Cohorts (A1 to A5): A staggered dosing schedule will be followed, for each cohort: 2 sentinel subjects (1 active and 1 placebo) will be dosed and the remaining 6 subjects will be dosed no sooner than the next day. Cohorts will be dosed sequentially in an ascending fashion. There will be at least 14 days between dosing of each dose level. Following completion of each dose level, a safety review committee (SRC) composed by at least the Investigator, a Sponsor representative, and an Independent Medical monitor will review the safety and tolerability data, as well as available PK and immunogenicity data up to Day 15, for at least 6 subjects in the respective cohort, as well as available PK and immunogenicity data. Decisions from the SRC may include whether to escalate to the next dose level, continue with a more conservative approach (slowing the increase in dose or repeating a dose level), suspending dose escalation until further review of study data, stopping dose escalation, or terminating the study. Part B - MAD Cohorts (B1 to B4): Part B can be initiated only following review of the safety, tolerability, and PK data following dosing of the SAD Cohort 3 or 4, if deemed acceptable by the SRC. A staggered dosing schedule may be used for the first dose level, including 2 sentinel subjects (1 active and 1 placebo) initiating dosing first and the remaining 6 subjects initiating dosing no sooner than the next day. Cohorts will be dosed sequentially in an ascending fashion. There will be at least 14 days between dosing of each dose level. Following completion of each dose level, a SRC composed of at least the Investigator, a Sponsor representative, and an Independent Medical monitor will review the safety and tolerability data up to Day 15, for at least 6 subjects in the respective cohort, as well as available PK and immunogenicity data. Decisions from the SRC may include whether to escalate to the next dose level, continue with a more conservative approach (slowing the increase in dose, repeating a dose level, or exploring an alternative dosing regimen), suspending dose escalation until further review of study data, stopping dose escalation, or terminating the study. Part C - IV Cohorts (C1 and C2): Part C can be initiated only following review of the safety, tolerability, and PK data following dosing of the SAD Cohort 3 or 4, if deemed acceptable by the SRC. A staggered dosing schedule will be followed for each cohort: 2 sentinel subjects (1 active and 1 placebo) will be dosed first and the remaining 6 subjects will be dosed no sooner than the next day. Cohorts will be dosed sequentially in an ascending fashion. There will be at least 14 days between dosing of each dose level. Following completion of each dose level, The SRC composed by at least the Investigator, a Sponsor representative, and an Independent Medical monitor will review the safety and tolerability data up to Day 15, for at least 6 subjects in the respective cohort, as well as available PK and immunogenicity data. Decisions from the SRC may include whether to escalate to the next dose level, continue with a more conservative approach (slowing the increase in dose or repeating a dose level), suspending dose escalation until further review of study data, stopping dose escalation, or terminating the study. Some alterations from the currently outlined dose and/or dosing regimen may be performed, but the dose to be administered in a given cohort will not exceed the one currently outlined in the protocol. Part D (Multiple Dose Patients) - Cohorts D1 to D3: Part D may be initiated following submission and review of an interim analysis report from Parts A through C of the study by both the SRC and Human Research Ethics Committee (HREC). Part D may commence only after approval to commence from both committees is granted. A staggered dosing schedule may be used for each cohort. Two (2) sentinel subjects (1 active and 1 placebo) will initiate dosing first (a minimum of 1 hour apart from end of dosing for first sentinel patient to start of dosing for second sentinel patient) and the remaining 8 subjects will initiate dosing no sooner than the next day (each dosed at least 15 minutes apart from end of dosing for previous patient to start of dosing for following patient). Cohorts will be dosed either sequentially or with partial overlapping and the SRC will meet to discuss relevant data collected after completion of at least the first cohort.

For Each part of the study, a staggered dosing schedule may be used for the first dose level, in each cohort including 2 sentinel subjects (1 active and 1 placebo) initiating dosing first and the remaining 6 subjects for Part A-C and 8 subjects for Part D initiating dosing no sooner than the next day. Each study part (A, B, C, and D) will be completed sequentially, but with partial overlapping. Part B and C may only be initiated after review of the safety, tolerability, and PK data following dosing of the SAD Cohort 3 or 4. Part D may be initiated when safety tolerability and PK data are known and deemed acceptable by the SRC for multiple doses in Part B, at least at the same concentration to be administered in Part D.

To evaluate the pharmacokinetics (PK) of LQ036 after single and multiple doses of LQ036 administered via inhalation and IV routes in healthy subjects and patients with mild Asthma.

Vdss/F: apparent volume of distribution at steady-state, calculated as dose / (Kel \* AUC0-inf)

Time frame: Up to 2 Weeks

To evaluate the change in fraction exhaled nitric oxide (FeNO) after multiple doses of LQ036 administered via inhalation in patients with mild asthma.

At screening, on dosing days (Days 1 to 10, within 60 minutes prior to dosing), on Days 11, 12, and at discharge (Day 13), as well as on Days 15±1, 22±1, 29±1, and at study exit (Day 36±1).

Time frame: Up to 6 weeks

Secondary Outcomes

To compare the PK of LQ036 after administration via inhalation and IV routes

Serum levels of LQ036 will be quantified for PK analysis by a validated enzyme linked immunosorbent assay (ELISA) method.

Time frame: Up to 2 weeks

To compare the safety and tolerability of LQ036 after administration via inhalation and IV routes (AUC0-24 versus AUC0-τ)

Comparisons between Day 1 and Day 10 PK parameters: AUC0-24 versus AUC0-τ will be done by Analysis of variance (ANOVA)

Time frame: Up to 2 weeks

Comparisons between Day 1 and Day 10 PK parameters: Cmax versus Cmax ss will be done by Analysis of variance (ANOVA)

Time frame: Up to 2 weeks

To compare the safety and tolerability of LQ036 after administration via inhalation and IV routes (Tmax versus Tmax ss)

Comparisons between Day 1 and Day 10 PK parameters: Tmax versus Tmax ss will be done by Analysis of variance (ANOVA)
