Free Patient Recruitment Webinar:  The Art and Science of Media Planning and Buying


Human behavior has changed dramatically over the past decade, resulting in immense media fragmentation.  Today’s society offers an ever increasing choice with regard to consumption of media. The selections range from thousands of websites to hundreds of television stations to a variety of print publications appealing to vast and niche audiences.  This media fragmentation makes it increasingly difficult to reach and connect with your target audience.  There is both an “art” and “science” to planning and buying media for your patient recruitment programs.

Join me for this webinar, and learn:

     -How to accurately define your target audience

     -The best approach to take when working with media outlets

     -Ways to craft and deliver a message that is aligned with your media selections

     -How to monitor and optimize your patient recruitment campaign — and what recourse you may have when something goes wrong

CSSi Announces the Establishment of their Newest Division, CSSi LifeSciences; Will Support All Phases of Pharma Product Lifecycle

June 11, 2014

Glen Burnie, MD– CSSi, the leader in patient recruitment solutions for the clinical research industry, recently announced the formation of the company’s LifeSciences division.  This entity was created to complement our other service offerings by providing guidance and support for all phases of the product life cycle, from product concept and early planning to post approval compliance and surveillance.

CSSi LifeSciences provides innovative solutions which span the entire lifecycle of a new drug or device by reducing time to market, development costs, and resources.  Their portfolio of service offerings includes Health Authority Interactions, Regulatory Consulting, FDA/EMEA Advisory Committee Support, Clinical and Site Planning Services, and Regulatory and Clinical Communications Services. Since 2005, the LifeSciences team members have worked on more than 150 new drugs, biologics, and devices, and have extensive “First in Class” and “First Indication” experience. 

The LifeSciences team is being led by James Sergi, who has held various positions in academic nursing and cancer research, before co-founding and serving as CEO of a healthcare services and drug development company. His academic and medical experience includes Director and Administrator for the Department of Experimental Therapeutics at the Cleveland Clinic Cancer Center, Associate Professor of Medical-Surgical Nursing at the Case Western Reserve University Frances Payne Bolton School of Nursing, Lecturer for Oncology Nursing at the Cleveland State University College of Nursing, and Research Manager of Hematology and Medical Oncology at the Cleveland Veterans Administration Medical Center Research Division.

“The regulatory industry is constantly changing and evolving which presents continued challenges to pharmaceutical companies who are tasked with bringing new drugs to market quickly while maintaining cost efficiency,” states Chris Trizna, President of CSSi. “CSSi is thrilled to bring Jim Sergi on board as President to lead this new division. His extensive experience in the regulatory industry will allow us to increase our global operation capabilities as pharmaceutical companies are relying more on outsourcing regulatory needs to market their new medicines.”  

“CSSi LifeSciences will allow clients to be more effective and knowledgeable when dealing with the complex arena of regulatory operations and affairs.  I am very excited to join CSSi and help them broaden their service offerings to include regulatory information solutions,” commented James Sergi, newly appointed President of CSSi LifeSciences division. “With offices in Baltimore, San Francisco and London, CSSi LifeSciences is positioned to drive successful outcomes for pharmaceutical companies of all sizes and specialties.”

  •    It was a long journey, and we are all delighted at the successful outcome. We appreciate the support [the CSS] team provided along the way. Hopefully, we can work together again in the future.

  •    You have made our advertising so much easier and taken time off my plate, which is always appreciated. We look forward to a prosperous relationship ahead!

  •    …greatly appreciate your help throughout the year. You have taken a significant burden off my shoulders over the past several years.

    -Investigative Site
  •    I cannot begin to express my appreciation for a job well done and the continued efforts you place to ensure that this study was a success! Our candor and transparency has been refreshing and I am fortunate to have partnered with such a great group of patient recruitment and retention experts! You are wonderful!

  •    To begin with, please let yourteam know that everyone is doing a FANTASTIC job with compiling the information for this difficult study.

  •    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.

    -Multi-specialty Investigative Site
  •    It is a PLEASURE working with the CSS team! I could not be more pleased with the progress thus far and feel that the communication and team oriented approach is EXACTLY what we are looking for.
