Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
RIP1 mediates the downstream effects of multiple biological activities including inflammatory responses. Therefore RIP1 inhibitors may be advantageous over selective inhibitors for a specific cytokine to reduce inflammatory response. SIR1-365 is a Receptor-Interacting Protein1 (RIP1) inhibitor that is under development as a new investigational drug for the treatment of inflammatory diseases.

Type III prostatitis is also known as chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Currently, there is a lack of a clear evidence proved effective treatment.

This will be a multicenter, randomized, double-blinded, placebo-controlled study to evaluate safety and preliminary efficacy of SIR1-365 in patients with CP/CPPS. Enrolled patients will take two 100mg tablets of either SIR1-365 or matching placebo orally, two times a day for 28 consecutive days. Patients will return to the clinical site on Days 7 (±1 day), 14 (±1 day), be contacted by telephone on Day 21 (±1 day), 28 (±2 days) end of treatment and 42 (±5 days) follow up visit/end of study to receive all the activities scheduled for the respective visits. The afternoon dose for Day 28 (±2) or last visit day will not be administered.

Study staff will instruct enrolled patients to take the study medication exactly as instructed as compliance is necessary for patient safety and for the validity of the study. Excluding the follow-up visit, patients will take their morning dose on the days they attend the clinical site. Study staff will contact patients on a weekly basis to schedule their next clinic visit and to remind them to take their study medication. IP bottles will be returned to the clinical site on Days 7, 14 and 28. Study staff will perform a pill count to determine treatment compliance and record the information in the source.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All eligible subjects will be randomised using interactive response technology (central randomisation - computer), developed prior to the initiation of the study.

The dispensed IP label will include the subject's name, randomisation number and will state 'SIR1-365 or matching placebo' and the dose. The label will not contain any unblinded information, to disclose whether the content(s) of the bottle are SIR1-365 or placebo.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software

Summary
Brief summary
SIR1-365 is a potent and selective allosteric kinase inhibitor of RIP1 with favorable drug-like properties in vitro and in vivo. RIP1 inhibitors may be beneficial for the treatments of degenerative diseases including neurodegenerative and systemic inflammatory diseases.

The primary objective is to assess the overall safety and tolerability of SIR1-365 administered orally at 200 mg, two times per day (BID) for 28 days relative to the placebo group. The secondary objectives are to assess the effects of SIR1-365 on clinical efficacy endpoints, and the biomarkers indicative of inflammation, and target engagement as well as the plasma SIR1-365 levels.
