For new and updated trial submissions, we are processing trials as quickly as possible and appreciate your patience. We recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
A total of 18 participants will receive three single subcutaneous doses of gerilimzumab (5 mg or 20 mg) or placebo at Day 1, Day 28, Day 56 .

Each dose will be administered by a train site staff (i.e. nurse) and will be documented in the clinic notes.

Treatment: Drugs
Comparator / control treatment
Placebo (10 mM acetate, 9% (w/v) sucrose, 0.006% (w/v) polysorbate 20) subcutaneous injection.
Control group

Primary outcome [1] 295936 0
Safety and tolerability of gerilimzumab administered as 3 subcutaneous doses at 4 weekly intervals .

Outcomes are measured by evaluating physical exams, ECGs, vital signs, clinical laboratory results, and adverse events

This is the first time gerilimzumab will be given to humans in multiple doses. Therefore, the risks to human participants have not yet been fully evaluated. Gerilimzumab is a “monoclonal antibody” and while nothing in the non-human drug development data suggest it, it is likely based on other human studies with monoclonal studies, you may experience symptoms of apparent allergic reaction, also known as “cytokine release syndrome”. Symptoms of this can vary but can include:

*Mild to moderate fever, chills, headache, nausea, and vomiting
*Moderate to severe symptoms such as swelling of the skin, low blood pressure, and pulmonary infiltrates (e.g. blood and mucus in the lung).

Although nothing in pre-clinical and preliminary clinical testing of gerilmzumab to date indicates that an allergic reaction is likely, a reaction to any drug is possible. Some symptoms of allergic reactions are:
* Rash
* Wheezing, or difficulty breathing
* Dizziness or fainting (also a possible outcome of a drop in blood pressure)
* Swelling around the mouth, throat or eyes
* A fast pulse
* Sweating

Participants will be closely monitored with regular assessment of vital signs, physical examinations, ECGs, and safety blood results. The study doctor will be looking out for side effects.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A total of 18 participants will be enrolled into 2 cohorts. Each cohort has 9 participants with 6 randomized to received gerilmzumab ( cohort 1: 5 mg; cohort 2: 20 mg) and 3 participants to receive placebo.

A randomisation list will be generated by an Unblinded Statistician at CNS and will be transferred electronically to the Investigational Site at least 2 days prior to enrolment.

Eligible subjects enrolled into the study will be assigned a randomisation number by the Nucleus Network Unblinded Pharmacist in accordance with the Randomization List generated by CNS.

The Randomisation List details the randomisation numbers and the associated treatment.

Each participant will receive the treatment which corresponds to their randomisation number (as assigned in the Randomisation List).

The Randomisation List will be available only to clinic pharmacy staff preparing the drug who are not involved in any other aspect of the study. The Randomisation List will not be made available to the Sponsor, subjects, or members of the staff responsible for the monitoring and evaluation of safety assessments (i.e. all blinded study members) until
study completion and database lock, unless a full unblinding of the study is required.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The generation of the Randomisation List for each cohort will be performed by a CNS Unblinded Biostatistician using the computer program SAS (registered trademark) v9.4 or later.

Statistical methods / analysis
Safety population: All participants who are dosed will be included in the safety population.

Pharmacokinetic population: The pharmacokinetic population will include all participants having sufficient serum concentration-time data to determine at least 1 pharmacokinetic parameter.

The sample size chosen for this study was selected without statistical considerations. It has been determined adequate to meet the study objectives.

No formal inferential statistics will be performed on safety assessments.

Listings and summaries for all safety data will be presented using the Safety Population.

Descriptive statistics (mean, SD, median, minimum and maximum) will be calculated for summaries of continuous safety data and frequency counts and percentages (where appropriate) will be calculated for summaries of discrete/categorical safety data.
