Clinical trials test whether or not, and how, a specific behavior is altered by a medical treatment, device, etc. They are mainly used to find out if a new treatment has side effects and is safe and effective. Some examples of clinical trials that are conducted include Cancer and HIV/AIDS. The reasons these trials are conducted are reducing the chances of diseases, finding a cure, or finding easier detection techniques. For example, clinical trials are preventing global diseases in Barbados.
Usually, only 10 percent of new drugs passed clinical trials before going onto the market, but now it is up to 15 percent, which shows that the qualifications and standards for new medications are higher. The probability of success (POS), within the process of getting a new medication approved, allows researchers to determine whether they want to pursue a drug. This helps with time management and effectiveness of preventing, treating and controlling diseases.
Clinical trials increase the chances of having effective treatments made available to the public and possibly at a lower cost. Typically, approximately 1,000 potential new medicines are tested before making it to the clinical trial. After passing this screening, there are four phases in the process of clinical trials: testing the toxicological effect; testing the safety, effectiveness, and dosage of medications; getting the FDA’s approval; and examining new uses for already approved drugs and treatments. These phases aid in preventing global diseases in Barbados.
As of 2008, there was a combined death rate of 3,208 people in Barbados, due to various cancers including prostate, breast and lung cancer. Preventing global diseases in Barbados, such as prostate cancer among men and breast cancer among women, are a top priority.
Most cancer screening and early detection methods, such as a cervical cytology (PAP), mammograms and bowel (physically or through colonoscopy), are available through primary health care. However, at least 7,000 households live in poverty and possibly lack access to basic health care.
Funding Clinical Trials to Help Prevent Global Diseases
Some challenges faced in forming and maintaining clinical trials, that could help in preventing global diseases in Barbados, are the timeline and funding. A proper, successful clinical trial may take 10 to 15 years to complete. On the other hand, the clinical trial for a respiratory disease may cost approximately $35,300,000.
One possible solution to the issue of funding is to increase the 7.5 percent of Barbados’ gross domestic product (GDP) dedicated to health, or become more active in nonprofits and earn money through awareness and action.
For instance, the Clara Lionel Foundation is a nonprofit organization started by singer Rihanna and has successfully opened the Queen Elizabeth Hospital and installed three cancer detection pieces: the equinox external beam, the brachytherapy system and the gamma camera CT scan. These three pieces of equipment help analyze and eradication cancer throughout the body.
By investing in Barbados’ GDP and more nonprofits, such as the Clara Lionel Foundation, clinical trials will be able to continue working toward preventing global diseases in Barbados.
