The 4-1-1 on Clinical Trials

Clinical trials are an opportunity to gain access to new research treatments before they are widely available and to receive expert medical care at a leading healthcare facility. In an effort to improve research transparency, below are key-points to know about clinical trials and how they strengthen the validity and value of medical breakthroughs.

What are Clinical Trials?
Clinical trials are research studies that test how well new medical approaches work in the human body. Each study answers scientific questions and attempts to find better ways to prevent, screen for, diagnose, or treat a disease. Every clinical trial has a protocol or action plan, and they describe:

• What will transpire in the study
• Detailed criteria about who can participate
• How the study will be conducted
• Why the trial is necessary

Why Conduct Clinical Trials?
Clinical trials produce data for healthcare decision making and contribute invaluable information about the benefits and safety of new and existing therapies. The results for therapeutic clinical trials can provide doctors, families, and patients with new drugs and treatments.

Clinical Trial Process
A healthcare team conducts health screenings to ensure that a participant qualifies for the clinical trial.
Once a participant is eligible, instructions are provided to make certain that visits and study procedures are fulfilled for best results.
Medical vitals are carefully monitored.
Once the clinical trials are complete, the participant may contact the research team for questions.

Phases of Clinical Trials

Phase I – The experimental drug or treatment is tested in a small group of people (10-80) who are often the first to receive a new therapy or a new combination of therapies. In this phase, researchers evaluate its safety, dosage range and identify side effects.

Phase II – The experimental drug or treatment is given to a larger group of people (100-200). Researchers continue to evaluate the treatment and if it is further effective.

Phase III – The new drug or treatment that has shown promising results is used on a larger group of people (1,000 – 3,000) and compared to the current standard of care for that specific disease.

Phase IV – Post marketing studies delineate additional information including the drug’s risks, benefits, and optimal use.

Volunteering in clinical trials helps future generations advance medical research, and provides a sense of hope for the future. If you are interested in volunteering for a clinical trials, begin your search by visiting our nationwide database at www.MyClinicalTrial.com.

Study Enrolls Three Months Ahead of Schedule when CSSi Goes the Extra Step in Special Population Recruitment

May 14, 2015

Glen Burnie, MD – CSSi, (www.CSSiEnroll.com) the leader in patient recruitment solutions for the clinical research industry, recently partnered with a major pharmaceutical company to support the recruitment and enrollment of a special population study. The overall enrollment goal was 1,200 patients using 110 sites within 12 months. The protocol required at least 15% (180) Hispanic and 20% (240) African American patients.

There were many challenges with this study, including competition for patients within this indication, lack of awareness about clinical trials, fragmented implementation of tools and tactics, need for education about the study, maintenance issues with screening activities at the site, and lack of study coordinator bandwidth to complete recruitment activities.

CSSi worked with each site to develop the most appropriate recruitment plan based on their patient population, local community demographics, and overall recruitment needs. CSSi developed a recruitment strategy for each of the different target audiences along with race specific messaging to be used with sites where the demographics were highly weighted toward the group. They utilized best practices in recruiting these special populations, including involving the investigators in the community, focusing on community-based outreach as it is a proven tactic for reaching people of Hispanic heritage.  Also, targeting African American patients with radio advertising, as it has been the most successful tactic for this population. Northern urban sites focused on African American populations while Southern sites focused on the higher density of Hispanic populations within these regions.

While targeting special populations with customized tools and tactics, CSSi contributed 634 non Hispanic/Caucasian patients representing 52 % of enrolled patients. 220 of the 180 patients who identified themselves as Hispanic were enrolled, and 346 of the required 240 African American patients were enrolled. There were high screening rates at 75% of the sites, due to custom enrollment planning, and this was the main reason for finishing the study three months early – meeting recruitment goals in nine months time.

  •    I would not hesitate to use CSS again! Your team has been an absolute pleasure to work with and I consider us friends as well. If you are ever in the Raleigh area, please let me know.

  •    We had the phones ringing off the hook for a few days, and we ended with approximately 60 individuals who sounded like viable screeners from the contact list. They are spread out over the next six weeks. Up to this time we have only screened about 30 others (before campaign) had 16 that were cultured and four successfully enrolled, so we are running about 11% from screen appointment to successfully enrolled! By the way, overall this is the best ad response we have ever had!

    -Dermatology Investigator
  •    If this sounds like a "paid advertisement" for CSS, it's not. I just can't say enough good things about how they have helped us grow as a site by putting our name out there in a very professional way. To me it only makes sense to use CSS or a company like them (I just think they are the best one). We are in the business of research, not advertising. Let the experts in advertising handle that job for your site and put your energy into doing what you do best…research.
