Versiti joins colleagues across the medical and research community in mourning the loss of Lynn Malec, MD, MSc, Program Director at Versiti's Comprehensive Center for Bleeding Disorders and Pharmacy, and an Associate Investigator at Versiti Blood Research Institute. Dr. Malec was a physician-scientist whose work advanced care and hope for people living with bleeding disorders, and we extend our heartfelt sympathy to her loved ones and to the many patients, trainees, and colleagues whose lives she touched. 

Dr. Malec brought together clinical care, research, and education to improve patient outcomes across our region and beyond. Her work helped expand access to innovative therapies, including gene therapy, and strengthened the care model for individuals and families living with complex bleeding conditions.

HEMGENIX is an FDA-approved gene therapy for adults with hemophilia B who currently use factor IX prophylaxis therapy, have experienced life-threatening bleeding, or have repeated serious bleeding episodes. Through a single intravenous infusion, HEMGENIX delivers a functional factor IX gene to liver cells, enabling the body to produce its own clotting factor. Clinical studies demonstrate that 94 percent of patients receiving HEMGENIX can discontinue regular factor IX infusions.

"From 2014 to 2019, I endured four ankle surgeries because of advanced arthritis from hemophilia B," said Cody Gunst, a CCBD patient. "If gene therapy had existed then, I wouldn't have two fused ankles now. But this treatment changed everything that came after."

Before gene therapy, Cody required approximately four factor infusions per month — vigilance that shaped every aspect of daily life. Within 60 days of receiving HEMGENIX, Cody’s factor IX levels increased from less than 1 percent to more than 12 percent.

Bleeding and clotting disorders require specialized expertise that goes beyond general hematology. At Versiti CCBD, our board-certified hematologists dedicate their practice exclusively to these complex conditions, developing the nuanced clinical judgment necessary for optimal diagnosis and treatment. This specialization means we recognize subtle presentations, anticipate complications, and personalize treatment.

We recognize that these conditions affect entire families, not just individual patients. We provide education, support, and resources for parents, siblings, partners, and caregivers, recognizing that family well-being has a direct impact on patient outcomes. Whether you're navigating a new diagnosis, managing complications, planning for surgery or exploring cutting-edge treatments like gene therapy, our team brings both sophisticated clinical knowledge and genuine partnership to every interaction.

As a “lifespan clinic,” Versiti Comprehensive Center for Bleeding Disorders’ pediatric and adult hematologists are dedicated to caring for patients of all ages. Our longtime medical Director, Joan Gill, MD, established CCBD as a center of excellence committed to improving the lives of patients. Today, our staff of physicians, nurse practitioners, nurses, physical therapist, genetic counselors, social workers, psychologist, pharmacy specialists and research coordinators continue this legacy of excellence in Dr. Gill’s memory.
