Description of intervention(s) / exposure
This is a Phase 1 Open-Label Study in Subjects with Mild to Moderate Idiopathic Pulmonary Fibrosis (IPF), using a Multiple Ascending Dose (MAD) inhalation of nebulised SM04646.

A previous study has been conducted using single doses of SM04646 in healthy volunteers. This is the first study in humans where multiple doses of SM04646 will be given. It is also the first study where SM04646 will be given to subjects with the health condition of IPF.

SM04646 will be supplied as a single-use nebulized Inhalation Solution in vehicle containing mannitol and tyloxapol. Subjects will be treated with 28 consecutive daily doses of nebulized SM04646 Inhalation Solution and will be followed for approximately 30 days after last treatment. At a minimum, study medication administration on Days 1, 2, 7, 14, 21, and 28 will be performed by qualified and designated study staff at the study centre; on all other dosing days, study medication administration will be performed either at the study site or at the subject’s home with support from a medically qualified staff member.

Dose escalation levels will be 2.0 mg, 7.0 mg, and 20.0 mg. Enrollment of subsequent dose level cohorts will occur only after the safety data from the previous dose level cohort are reviewed and approval for dose-escalation is granted by the Safety Review Committee (SRC). Upon review and approval of escalation to a subsequent dose level, no further subjects will be enrolled at the current dose level. The exception to this, however, is if there is a Dose Limiting Toxicity (DLT). A DLT is defined as any of the following occurring within the 28-day dosing period or within follow-up and determined to be at least possibly related to the study medication by the Principal Investigator:

* A Grade 3 or higher adverse event (AE) per the Common Terminology Criteria for Adverse Events (CTCAE) v4.03

* A serious adverse event (SAE)

The SRC will convene after each DLT and following the completion of the dosing period for each dose level cohort (after Day 28) to determine if further enrolment may continue for a given cohort or if all further enrolment is to cease.

If 3 or more unique subjects experience DLTs following the first dose of study medication administration in a given cohort, the Maximum Tolerated Dose (MTD) will be considered exceeded and dosing for the study will cease. If all cohorts are enrolled without exceeding the MTD, the Maximum Recommended Dose (MRD) will be the highest dose cohort enrolled.

Intervention assignment
Other
Other design features
This study is a multiple-dose, dose-escalation safety study in subjects with mild to moderate IPF.

Eligible subjects will be treated with 28 consecutive daily doses of nebulized SM04646 Inhalation Solution. Subjects will be observed for ~30 additional days after treatment, for a total per subject study period of ~60 days.

Dose escalation will take place after the applicable cohort completes the dosing period and if dose escalation is approved by the Safety Review Committee (SRC). The SRC will review the safety and tolerability findings at each dose level after the dosing period is completed (Day 28) and after each Dose Limiting Toxicity (DLT). The SRC must agree that the data support continuation of the study and/or dose escalation.

The occurrence of clinical signs or symptoms, of abnormal laboratory, pulmonary function or ECG assessments, or of oxygen saturation levels suggesting toxicity may result in a decision to reduce the incremental increase of planned dose escalations or not to evaluate any additional dose(s) of SM04646 Inhalation Solution.

Type of endpoint/s
Safety
Statistical methods / analysis
The sample size for this study was not based on statistical power calculations, but is consistent with typical sample sizes used for similar studies to assess preliminary safety and PK.

The general analytical approach for all endpoints will be descriptive in nature, providing a summary and estimate of the safety profile of SM04646 Inhalation Solution in subjects with IPF. No formal statistical hypothesis testing will be conducted in this study.

Demographic variables will include age, sex, race, ethnicity, height, and weight. For continuous variables, number of subjects in the analysis, mean, standard deviation (SD), median, minimum, and maximum will be reported. All categorical endpoints will be summarized using frequencies and percentages.

Safety analyses will be conducted on all subjects who received any study medication administration.

Plasma concentration and PK parameter summaries will include descriptive statistics, as appropriate. PK parameters will only be estimated if plasma concentrations are detectable at a sufficient number of timepoints.

PK analyses will be conducted on all subjects that missed 4 or less doses and received in-window dosing on Days 1, 27, and 28.
