Investigating a new therapy to help people living with generalized Myasthenia Gravis (MG).
What is the KYSA-6 phase 3 clinical trial?

Multiple leading medical centers

Eligible participants will have tried previous treatments, but their disease is still not well controlled

KYSA-6 is a phase 2/3 trial. Phase 3 is an expansion of KYSA-6 and is taking place in multiple leading medical centers in the US and around the world. The phase 2 portion of the KYSA-6 study is fully enrolled. Please contact us for additional information and to find out which site might be nearest to you.
Who can take part in the KYSA-6 phase 3 clinical trial?
You may be able to participate in the KYSA-6 phase 3 trial if:

You are 18 to 75 years old.

You have been diagnosed with generalized MG according to specific criteria.

You have tried previous treatments, but your disease is still not well controlled.

You are positive for acetylcholine receptor (AChR) or muscle-specific kinase (MuSK) autoantibodies.
This list does not include all the trial participation criteria and additional criteria may apply.
What will happen in the KYSA-6 phase 3 clinical trial?
If you are selected to participate, one of the doctors running the trial (or someone on their behalf) will talk with you about what you can expect as a participant in the trial so that you understand and are comfortable with what it means to take part. This is called informed consent.
If you are able to enroll in the trial, these are the key steps you will be involved in:

CAR T-cell therapies can be associated with cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), which may be potentially serious or life-threatening but generally resolve within the first month after treatment.
- Symptoms of CRS include fever, nausea, feeling tired (fatigue), and body aches and can progress in severity and may include low blood pressure, shock, and potentially organ failure.
- Symptoms of ICANS include fatigue, uncontrolled movements (tremors), impairment in thinking, loss of speech, muscle weakness, or more severe symptoms such as seizures and swelling in the brain.
People receiving this treatment are always in the care of a doctor, who monitors them closely for these side effects and can treat their symptoms to help prevent their worsening.
If you are interested in taking part in the trial, your doctor can refer you to a trial site or you may reach out directly via this site to learn more and be referred. If you are selected for screening, the trial doctor will assess you to confirm your eligibility for trial participation. This may include performing additional tests. The trial doctor will also explain the detailed criteria for participating. This trial has multiple sites in the United States and internationally. To participate in this clinical trial, you will need to travel if you do not live near a trial site.
Participant Accommodations: We aim to make every participant's KYSA-6 clinical trial experience as easy as possible. Accommodations for trial participation may be available and may include travel and caregiver support.
