The tennis legend joins argenx’s Go for Great initiative aiming to spread awareness and educational information about the disease.

Argenx announced its partnership with nine-time Grand Slam tennis champion Monica Seles. The tennis icon expressed her support for argenx’s “Go for Greater” campaign, speaking up about her personal experiences suffering from Myasthenia Gravis (MG).

"I would be playing with some kids or family members, and I would miss a ball. I was like, ‘Yeah, I see two balls.’ These are obviously symptoms that you can’t ignore,” said Seles. “And, for me, this is when this journey started. And it took me quite some time to really absorb it, speak openly about it, because it’s a difficult one. It affects my day-to-day life quite a lot.”²

Champion mentality

Seles decision to partner with argenx stemmed from mutual goals of aiming to improve awareness as well as understanding of MG. The initiative will also assist those suffering from MG with the ability to provide the necessary resources and tools required to treat and support MG patients. These goals reflect the collaboration’s efforts in providing MG patients a sense of community, informational resources, and treatment options.

Karen Massey, chief operating officer, at argenx, touched on this topic, saying, “At argenx, we are committed to supporting the MG community by fostering understanding and connection. We applaud Monica for sharing her personal story and are excited to collaborate with her to amplify the voices of MG patients and caregivers. Her journey and dedication to this cause will help people living with MG engage in meaningful conversations and build a supportive network around this challenging disease. Together, we hope to shine a light of understanding and support for those affected by MG.”¹

Slamming Myasthenia Gravis

An estimated 120,000 Americans are reported to be living with MG, an autoimmune neuromuscular condition, commonly affecting women under 40 and men over 60. People living with the disease experience a variety of symptoms such as;

• Lower & upper body weakness
• Drooping in one or both eyelids
• Fatigue
• Challenges walking
• Blurred or double vison
• Difficulties speaking
• Consistently altering facial expressions

Seles’ collaboration with argenx is expected to raise awareness and information about MG prior to the U.S Open set to take place August 24. Seles talked about the impact Mg has had in her personal life as well as her professional life, saying, “My MG journey over the past 5 years has not been an easy one. I felt isolated and defeated as many of the activities I enjoyed were no longer physically possible for me. I’ve since realized that by sharing my story, I can raise awareness of this disease, empower patients to advocate for themselves and help them connect with the MG community for support. I am excited to partner with the argenx team to inspire others living with MG to rally against this disease, pursue their goals, and live a fulfilling life. We’re all in this together.”¹
