Problem (2-3 paragraphs)
Hunter syndrome currently has no cure. It is usually fatal, and very hard to catch symptoms at a young age. It is hereditary, passed down from the mother’s side, but only affects males, due to the son only inheriting the damaged X chromosome from his mother. Girls escape the effects of the disease because they inherit a healthy X chromosome as well as the damaged one, and that healthy X chromosome is able to function properly.
In this disease, the enzyme iduronate sulfatase is not produced properly, or is not produced at all. Because of the malfunctioning or missing enzyme, complicated sugars called mucopolysaccharides, more specifically the sugars dermatan and heparan sulphate, are not broken down and instead build up and affect many of the body’s systems.
The respiratory system can be blocked due to build up of tissues and sleep apnea is a common issue. In the heart, cardiovascular complications such as high blood pressure, heart murmur, and leaky heart valves are symptoms. Most people with Hunter syndrome don’t heal well and often have complications after surgery. This makes treatment for skeletal and connective tissue problems very difficult. Joint flexibility and motion is often impacted and impaired. Problems associated with the buildup of fluid and tissue around the brain and spinal cord are difficult to address because of the risks of treating these parts of the body that already exist. Seizures may be an eventual symptom of Hunter syndrome.
Previous attempted solutions (2-4 paragraphs)
Previous attempts have included long-term enzyme replacement therapy with Idursulfase medications delivered weekly through an IV. Unfortunately, once the treatment can be termed “long-term”, anti-idursulfase serum antibodies build up in the immune system and the treatment becomes much less effective. Because this is such a new area of study and medication, observations are still being made pertaining to the results of this drug and treatment.
Some of the side effects already observed in reaction to introducing idursulfase into patients’ bodies include serious allergic reactions, headache, fever, skin reactions and high blood pressure. Side effects have been seen to lesson over time, but the positive results of the treatment in regards to the enzyme replacement have also been seen to become less effective.
Current limitations/present need (2-3 paragraphs)
Biotechnology and its applications in medication is still relatively new, so scientists are still in the beginning stages of attempting to find cures with this new technology. Because of this, most of the developments in this field are still being studied for negative side effects or long-term results.
Hunter syndrome has not been cured yet, and treatments for it only limit the side effects. Some side effects that could arise would be a bad reaction to the product's introduction to the patients’ immune systems. It is also not clear whether the enzyme iduronate sulfatase can be produced in a similar way to insulin.
Your proposed/product (2-5 paragraphs)
We would use Chinese hamster ovary cells (abbreviated as CHO cells) in “cell production lines”, frozen in a cell bank or storage facility prior to use. These would provide the starter material for the genetic engineering process. To produce a the iduronate sulfatase enzyme, the gene for that enzyme would be obtained from human DNA and inserted into the CHO cells, causing them to express or "manufacture" the enzyme. Next we would purify the enzyme, so that unwanted substances are removed.The next step would be to prove that our product contains the correct enzyme. To do this, we would use the techniques of chromatography to check that our product is made of the correct substances. Then we would conduct tests to make sure that the iduronate sulfatase enzyme was functioning properly. To do this, we would use test tubes containing the mucopolysaccharides and add our product consisting of the iduronate sulfatase enzyme. If our product breaks down the sugar we would then know that our product functioned as intended. Afterwards, the product would be ready for development into a final product and would then be transported to a sterile area, where it would be put into its final packaging. In the last stage of the production process, we would fill the manufactured enzyme into vials using a sterile manufacturing process to prevent product contamination. At this point, the vials would be ready to be sealed, labeled, and inspected. Only after Quality Assurance (QA) approval would the iduronate sulfatase enzyme be shipped from the manufacturing facility.
Once our product has been made, the next stage is to introduce it to patients. Our product would be given once weekly by intravenous (IV) infusion, meaning that the medication would be delivered directly into your bloodstream, and from there to the body’s cells and organs to break down the mucopolysaccharide buildup. Treatments would typically be expected to last about three to four hours. The patient would receive an infusion once a week. A healthcare professional could possibly prescribe pretreatment medications, such as antihistamines or anti-fever therapies, to reduce the symptoms of any reactions that could occur during an infusion. These medications would be taken around 60 minutes before the start of the infusion. The IV would then be set up and the healthcare professional would typically prescribe the infusion to drip slowly into the vein for about three to four hours. During this time the healthcare professional would check vital signs and again when the IV needle has been removed and the process has ended.Citations (at least 5 credible, valuable sources of information)
