General observations regarding
Estimates of Funding Research:
- $70 million in research for DMD - compared to $5,654 million for cancer
- US tax dollars are paying for this
- We need a major shift to change this
Four stages of research prior to a new drug on the market from Dr. Brian: Phase I Designed to establish the effects of a new drug in humans. These studies are usually conducted on small populations of healthy humans to specifically determine a drug's toxicity, absorption, distribution and metabolism. Phase II After successful completion of Phase I trials, a drug is then tested for safety and efficacy in a slightly larger population of individuals who are afflicted with the disease or condition for which the drug was developed. Phase III The last pre-approval round of testing of a drug is conducted on large populations of afflicted patients. Phase III studies usually test the new drug in comparison with the standard therapy currently being used for the disease in question. The results of these trials usually provide the information that is included in the package insert and labelling. Phase IV After the drug has been approved by the FDA, phase IV studies are conducted to compare the drug to a competitor, explore additional patient populations, or to further study any adverse events.

"DMD can present genetically in four different ways, knowing your child's genetic disposition will help when searching out clinical trials for treatment" 1. Exon deletion 2. Exon skipping 3. Stop code signals PTC - (tricks system to ignore stop) Stopping too soon 4. Exon duplication Four DMD Goals: 1. A cure with minimal side effects 2. Better treatments with minimal side effects 3. Dedicated care to optimize quality/quantity of life 4. Minimize/Reverse scar tissue in muscular dystrophy While we wait: 1. Best supportive care possible 2. Avoid damaging things 3. Ramp up on favorable things |
