Trial Review

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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - JNJ-63733657
Treatment: Drugs - Placebo

Experimental: JNJ-63733657 Low-dose - Participants will receive single dose of JNJ-63733657 low-dose administered by intravenous (IV) infusion every 4 weeks during the double-blind treatment period. Participants will have an option to continue with the long-term extension (LTE) phase of the trial and will continue to receive the same treatment and dose during the LTE treatment period.

Experimental: JNJ-63733657 High-dose - Participants will receive single dose of JNJ-63733657 high-dose administered by IV infusion every 4 weeks during double-blind treatment period. Participants will have an option to continue with the LTE phase of the trial and will continue to receive the same treatment and dose during the LTE treatment period.

Placebo comparator: Placebo - Participants will receive single dose of matching placebo to JNJ-63733657 administered by IV infusion every 4 weeks during double-blind treatment period. Participants will have an option to continue with the LTE phase of the trial and will be re-randomized in a 1:1 ratio to receive either JNJ-63733657 low-dose or JNJ-63733657 high-dose during the LTE treatment period.


Treatment: Drugs: JNJ-63733657
JNJ-63733657 low or high dose will be administered by IV infusion.

Treatment: Drugs: Placebo
Placebo matching to JNJ-63733657 will be administered by IV infusion.
