TWiPO #15 ~ MicroRNAs and hereditary cancer

Join host Dr Tim Cripe with his co-hosts  Drs Jim Geller, Lionel Chow, and Lars Wagner in a robust discussion with special guest Dr Kathryn Wikenheiser-Brokamp on the implications of DICER1, rare tumor registries, and difficult issues surrounding genetic counseling.

Kathryn A. Wikenheiser-Brokamp, MD, PhD, is an Associate Professor in Pathology and Pulmonary Biology at Cincinnati Children’s Hospital Medical Center. Her research is focused on pediatric and adult lung diseases, including cancer. She seeks to determine the molecular mechanisms underlying Rb/p16, p53, and Dicer1 pathway function in lung development and the pathogenesis of lung disease. Dr Wikenheiser-Brokamp holds a PhD in Developmental Biology, Developmental Biology and an MD from University of Cincinnati.

Papers discussed:

DICER1 syndrome: clarifying the diagnosis, clinical features and management implications of a pleiotropic tumour predisposition syndrome. J Med Genet. 2011 Apr;48(4):273-8.

Extending the Phenotypes Associated with DICER1 Mutations. Hum Mutat. 2011 Aug 31. doi: 10.1002/humu.21600.

Hu3F8 is now a reality at Memorial-Sloan Kettering

The Story of the Band of Parents and humanized 3F8

by Caryn Franca and Shirley Staples

It was summer of 2007.  A group of parents had asked Dr. Nai-Kong Cheung to meet and update them on new treatments for neuroblastoma at Memorial Sloan-Kettering Cancer Center.  Most had children with relapsed neuroblastoma; all knew the terrible odds.  Dr. Cheung, head of the neuroblastoma program at MSKCC, and a long-time proponent of antibody therapy, met with the group at Ronald McDonald House.  After the presentation, one dad posed a question.  “What,” he asked, “do you need, to give our children more treatment options?”   “Money” was the simple, yet daunting answer.

Dr. Cheung then described an important research goal—the development of a new, humanized form of the 3F8 antibody that had been used since 1986 to treat neuroblastoma at MSKCC.  Researchers believed the new version, “Hu3F8,” had the potential to be many times more effective in fighting neuroblastoma, but Dr. Cheung estimated that $2-3 million dollars would be needed to fund the development of the drug.  After the meeting, parents excitedly discussed this revelation. The consensus was that they could and would do whatever was necessary to make hu3F8 treatment a reality.  A crusade was born.

Within a matter of days, an online group had been created and parents had begun brainstorming.  The name of the new parent group came from a California dad:  the “Band of Parents.”  One group of parents began the discussions and eventually the legal steps to form a tax-exempt foundation. Seven dads began planning to bike across the United States to raise funds and awareness–a ride they called “The Loneliest Road” to reflect the daily challenges facing neuroblastoma families. Ultimately they raised over $200,000 for hu3F8. Soon there were 60 families in the “BOP,” and the energy was palpable, from garage and jewelry sales, to writing fundraising letters to friends, to telling individual stories to local newspaper reporters.

Donations began to pour in, some from as far away as the Middle East.  As December approached, a New York City mom conceived the idea of a massive bake sale of holiday cookies.  Over several weeks, parents, friends, and volunteers from the culinary world baked, packaged and shipped 96,000 cookies from a small rented kitchen, raising several hundred thousand dollars. A few months later, families in Virginia banded together to organize the “Rock’n for a Cure.”  Band of Parent funds were mounting.

The efforts that followed were too many and varied to detail, but the key phrase is “banded together” – parents of children with neuroblastoma, along with family, friends and perfect strangers, came together to raise the funds needed to create a new treatment option for children with neuroblastoma.  Great personal determination was required.  As the months passed, many Band of Parents members lost their child to neuroblastoma – including the parent who coined the name “Band of Parents,” the mother who conceived the cookie bake-off, three of the bikers on The Loneliest Road, and the first three presidents of the BOP.  However, parents pushed forward despite the grief and loss felt by all in the group.  Golf tournaments, yard sales, and concerts were organized, sometimes from hospital bedsides; holiday decorations, tee-shirts, and greeting cards were designed and sold.  Last but not least, the dedicated neuroblastoma team at MSKCC cleared the regulatory and many other hurdles to taking a new drug from the laboratory to the clinic.

In August 2011 the day finally arrived that so many had worked for and dreamed of.  A new phase 1 trial of hu3F8, a drug specifically designed for the treatment of neuroblastoma, opened at Memorial Sloan-Kettering, and the very first child received the promising new treatment. Ordinary people had accomplished an extraordinary labor of love. For all those involved, this will be remembered as a time when it was shown that, by banding together, a group of parents could give new hope in the battle against an aggressive childhood cancer.  Today, the members of the Band of Parents are still working to raise awareness and funding for research, so that someday no child will suffer from the terrible disease of neuroblastoma.

 

Editors note: the trial opened in August 2011 and is listed here: http://clinicaltrials.gov/ct2/show/NCT01419834

The trial allows for relapsed or refractory NB with evidence of disease, and is given without cytokines IL2 or GM-CSF.
