Healthy Clinical Trials in Las Vegas, NV

In this study, researchers will learn how the body processes litifilimab when it is given under the skin in 3 different ways. Currently, ongoing studies utilize pre-filled syringes (PFS) that can deliver litifilimab subcutaneously (SC), also known as under the skin. In this study, researchers want to learn more about new ways of delivering litifilimab SC using either an autoinjector (AI) or an on-body injector (OBI): Both devices are designed to deliver litifilimab in an automatic way, especially helping patients who may not be able to use their hands very well, or who may be afraid of needles. While the AI is handheld, the OBI device works by being placed on the skin and can help deliver the highest amount of litifilimab through a single injection. The main objective of this study is to learn how the body processes litifilimab after using the AI device or the OBI device, as compared to using the PFS method. The main questions researchers want to answer are: * What is the highest amount of litifilimab found in the blood after dosing? How much total litifilimab is found in the blood throughout the study? Researchers will also learn more about: Any medical problems the participants have during the study * Any injection site pain or reactions the participants may have. Any skin reactions to the OBI device * Any changes in the participants' overall health after receiving litifilimab. This study will be done as follows: * Participants will be screened to check if they can join the study. The screening period will be up to 4 weeks, after which selected participants will check into their study research center. * Participants will be randomly assigned to be in Part 1 or Part 2 of the study: * Part 1: Participants will receive SC injection(s) of litifilimab through either the AI device or through PFS. * Part 2: Participants will receive SC injection(s) of litifilimab through the OBI device or through PFS. * Participants will remain at their study research center for the first 8 days. After that, there will be a follow-up period for 17 weeks during which participants return to the center a total of 6 times. Each participant will be in the study for about 22 weeks. Read Less

The goal of this clinical trial is to learn if a single dose of the study drug, JST-010, is safe and tolerable when administered by injection into the arm or thigh muscle of healthy men and women aged 18 to 55. The main questions it aims to answer are: * Is a single injection of JST-010 safe? * What is the concentration of the JST-01 in the blood over time? * Do antibodies to JST-010 develop following a dose of JST-010? Researchers will compare JST-010 to Placebo to see if there are any differences in the safety and tolerability of a single dose at different dose levels. Participants will be confined to the clinic for the first 3 days. They will receive an injection on the second day, and then return for 9 more visits over the period of 1 year for: * Physical exam with vital signs * Electro-cardiogram (ECG) * Bood collection for clinical labs and research samples * Urine sample * Assessment of potential adverse effects and medications taken Read Less
