What are the differences between the ch14.18 antibody and 3F8?

Mark Dungan (Sydney's Daddy) — Thu, 19 Mar 2009 09:06:00 GMT

Although the ch14.18 and 3F8 antibodies both share the same target on neuroblastoma cells, the GD2 antigen, there are significant differences between them. The two antibodies differ in structure, in protocol design and availability, in comparisons of...(read more)

How has the antibody been used?

Mark Dungan (Sydney's Daddy) — Wed, 11 Mar 2009 15:05:00 GMT

How has the antibody been used? The ch14.18 antibody has been used in clinical trials both as a single agent and in combination with augmenting agents (cytokines) GM-CSF and IL-2. The chimeric antibody has also been tested as a single-agent therapy in...(read more)

What are the benefits of the ch14.18 antibody?

Mark Dungan (Sydney's Daddy) — Wed, 11 Mar 2009 15:04:00 GMT

The benefit of the ch14.18 antibody is that it has been shown in laboratory studies to be just as effective at targeting neuroblastoma cells as its murine counter parts. Ch14.18 has even been shown to induce lysis of neuroblastoma cells through the process...(read more)

What is ch14.18?

Mark Dungan (Sydney's Daddy) — Wed, 11 Mar 2009 15:02:00 GMT

Chimeric Monoclonal Antibody 14.18 (ch14.18) is an antibody that is part human and part mouse. It is a chimeric composed of the murine (mouse) monoclonal antibody 14.G2a and human constant region genes. The 14G2a antibody is a variant of the murine 14...(read more)

What are monoclonal antibodies?

One of the great things about being a mouse is the fact that mice do not naturally get neuroblastoma. Mice develop antibodies that attach to neuroblastoma cells thus alerting the immune system to come and kill the tumor cell. Neuroblastoma cells get killed...(read more)

How do antibodies kill neuroblastoma cells?

Mark Dungan (Sydney's Daddy) — Tue, 10 Mar 2009 09:26:00 GMT

Antibody therapy is believed to rely on three different methods to kill neuroblastoma cells. These are called antibody dependent cell-mediated cytotoxicity (ADCC), complement mediated cytotoxicity (CMC), and passive immunotherapy using the anti-idiotypic...(read more)

The more we learn the more things change

Mark Dungan (Sydney's Daddy) — Sat, 07 Jun 2008 11:36:00 GMT

One of the most interesting revelations of the 2008 ANR in Chiba, Japan from a parent of a child with neuroblastoma was the realization that the rules are always changing. I can not tell you how many times something I had previously accepted as fact was now coming into question. In the neuroblastoma research world the old adage "the more you learn the less you know" is more fact than fiction. Throughout the conference there were several examples of this type of revelation coming to fruition. None was more interesting than an abstract and presentation by Thorsten Simon from Children's Hospital, University of Cologne, Germany. ...(read more)

Reflections on the ANR

Mark Dungan (Sydney's Daddy) — Fri, 30 May 2008 14:10:00 GMT

As many parents know, the Advances in Neuroblastoma Research (ANR) Congress was held in Chiba, Japan during May 21-24, 2008. This was the first time it has been held in Asia. The ANR is held every two years in a new location throughout the world. In 2010 in will be held in Sweden. The ANR is an opportunity for neuroblastoma researchers and clinicians to meet, discuss and share the most current research in the world of neuroblastoma. During the 2008 ANR over 390 neuroblastoma research abstracts were submitted. All of them were reviewed and scored by at least 7 authorities. The event was attended by almost 500 researchers and clinicians from over 35 countries. The ANR is, by far, the world's largest neuroblastoma specific research conference and usually attracts all of the world's leading neuroblastoma researchers....(read more)

Neuroblastoma Bone (and Bone Marrow) Metastases

Mark Dungan (Sydney's Daddy) — Wed, 19 Mar 2008 17:18:00 GMT

On March 18,2008 Dr. Heidi Russell spent a little over an hour speaking with families about neuroblastoma bone and bone marrow metastases. Dr. Russell is a leader among the neuroblastoma research community. One of her interests is in understanding how and why neuroblastoma commonly metastasizes to the bone. Over the last several years, our understanding of the mechanism of bone metastasis in neuroblastoma has significantly improved. Like *** cancer and myeloma, neuroblastoma cells activate osteoclasts to form osteolytic lesions. Several targets for therapeutic intervention can now be identified. Inhibition of osteoclast activation by bisphosphonates has already shown to be effective in preclinical models of neuroblastoma bone metastasis and is now be tested in phase I clinical studies. Dr. Heidi Russell has been a pioneer in this area of research in neuroblastoma. During this presentation she provides a review of our current understanding of the mechanisms involved in bone metastasis in neuroblastoma and discusses how this knowledge is leading to the identification of new targets for treatment. This presentation is targeted towards parents of children with neuroblastoma and those with an interest in understanding how neuroblastoma metastasizes to bone....(read more)

Will we be hearing less about hearing loss?

Mark Dungan (Sydney's Daddy) — Tue, 29 Jan 2008 11:31:00 GMT

An interesting article was recently published in the January 15, 2008 edition of Clinical Cancer Research. The article, “Sodium Thiosulfate Administered Six Hours after Cisplatin Does Not Compromise Antineuroblastoma Activity”, points to new discoveries about a drug which could potentially protect our children's hearing from the devastating effects of therapy. ...(read more)
