Nice to Meet You

Kate and Matt Hare established The Callahan Murphy Hare Foundation in September 2021, following the April birth of their son Callahan, who was diagnosed with infant acute lymphoblastic leukemia (ALL) with the KMT2A genetic variant within hours of birth.

The family quickly learned Callahan’s prognosis — a devastating 20% chance of surviving three years. This pediatric cancer subtype has few treatment options and is resistant to treatment.

Though there weren’t many options outside of the standard of care, the family took a high risk gamble on a very aggressive protocol trialed in Japan on infant leukemia patients. This high risk nature of this treatment required Callahan to stay inpatient at Nationwide Children's in Columbus, OH for the first 8 months of his life while he received the aggressive treatment that was to ens with a stem cell transplant.

Throughout this time, the Hare's became immersed in the pediatric cancer world. As they learned more about their son's diagnosis, and the cancers of other pediatric patients they met during their stay, along with the minimal federal funding for pediatric cancers, Kate and Matt determined to be a part of the movement to help fill the funding gap for pediatric cancers. Perhaps most importantly, funding kinder treatments that are developed specifically for children.

Putting an exclamation point on their newfound purpose, Callahan’s planned bone marrow transplant - what was described as his best chance at a cure - was cancelled days before it was scheduled due to significant liver damage caused from the intense chemotherapy he’d received during his main course of treatment.

With a damaged liver, the ability for Callahan, then 7.5 months old, to withstand transplant was low. The family quickly pivoted into maintenance therapy with the hope that will sustain his remission. Big sister Campbell showed incredible resilience during this time. Keeping a positive, loving, sisterly attitude despite only meeting her new brother twice during these eight months before he finally came home in December 2021.

Callahan is currently in remission, loving life at home and working hard to catch up on his physical and cognitive delays caused by the chemotherapy he received. With immense gratitude, he completed treatment in April 2023. In August 2024, another milestone: he started preschool with a wonderful special needs program in his community.

Committed to Impacting:

The federal cancer budget allocating just 4% to research for the 112 types of pediatric cancer. Increased funding will impact the several types of pediatric cancer that have made minimal advancements, have no treatment plan or 0% survival rate.

The development of new therapies developed for pediatric cancer so children are no longer predominantly treated with therapies that were developed 70+ years ago. New, targeted therapies will help minimize the developmental delays, and in some cases other cancers developed, many pediatric patients currently struggle with.

Awareness for pediatric cancer and educating around the myth that it is rare. Over 17,000 families are touched by pediatric cancer every year. Due to the age of diagnosis, the sheer amount of time children who survive their disease deal with the repercussions and potential relapse compounds any so-called rarity. Add to that, the roughly 20% of pediatric cancer patients who succumb to their disease, lose an average 70 years of life. Driving awareness to raise funding will give children touched by cancer an improved chance to grow up and live their life.

Impacting the path forward for pediatric cancer treatments.

With an objective to support innovative research at children’s hospitals across the United States to support expanded protocols, trials and therapy development specific to pediatric cancers, CMHF has donated +$325,000 for pediatric cancer research at children’s research institutions, including Nationwide Children’s, Boston Children’s , Children’s National, Children’s Hospital of Philadelphia, and Cincinnatti Children’s since launching in 2021.
