What you need to know before you apply

What is this study testing?+

This study is a Phase I clinical trial to assess the safety, tolerability, and pharmacokinetic (PK) and pharmacodynamic (PD) profiles with single intravenous (IV) and intramuscular (IM) doses of ENA-001.

Is it safe? Who makes sure of that?+

This is an early study (Phase 1), focused mostly on safety. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.

Will I get a placebo instead of the real treatment?+

Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.

Do I have to stop taking my current medications?+

It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.

Does it cost anything? Will I be paid?+

The study treatment and study-related visits are provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.

Do I need insurance? Will anyone ask about my immigration status?+

No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.

What if English isn't my first language?+

You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.

Is my information private?+

Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.

Some requirements (like specific lab values or timing) are confirmed directly by the study team, not by us.
