ClinConnect Summary

This clinical trial is studying a medication called TLL-018, aimed at understanding its long-term safety and effectiveness in patients with rheumatoid arthritis (RA). This study is for people who have previously participated in another trial of TLL-018 and are now looking to see how well it works for a longer period. The trial is currently recruiting participants aged 18 to 75, including both men and women.

To qualify for the study, participants must have completed the earlier trial with TLL-018 within the last three months and should not have serious health issues that could make participation unsafe. Women who can become pregnant must not be pregnant or breastfeeding and will need to undergo pregnancy testing before joining. Participants can expect to receive TLL-018 and will be monitored for any side effects or changes in their condition throughout the study. Overall, this trial aims to provide more information about how TLL-018 can help manage rheumatoid arthritis over time.
