Clinical Trials

Clinical Research

We sponsor and support clinical research that answers scientific and healthcare questions which helps address unmet medical needs.  Clinical research is the process through which we can bring these innovative medicines to the people who need them.  Paratek focuses on products that can improve and save lives.  We are dedicated to providing safe and effective drugs and delivery systems that meet the needs of regulators, providers, payors, and most importantly - patients.  To do so, we conduct clinical studies that require the involvement of patients and healthy volunteers.

For information about clinical research in general, please visit the and read "About Clinical Studies".

Interested in participating as an investigator?

A clinical investigator’s role is pivotal in the development and advancement of new drugs. See the frequently asked questions (FAQ) which may address general questions you might have regarding clinical trials and investigators.

To begin the registration process, please send in a form containing the following information:



The majority of clinical trial investigators are physicians in private practice. You do not need to be associated with a medical school or teaching hospital to qualify as a clinical investigator. No previous experience as an investigator is needed to qualify.

Clinical investigators play an important role in the development of drugs, therapies and medical devices to combat disease, treat chronic and degenerative diseases, and improve the health of people throughout the world. Physicians in private practice are needed to join as investigators in these trials. By conducting clinical trials, you:

  • Remain at the cutting edge of your specific area of therapeutic interest
  • Gain recognition as a thought-leader within your professional community
  • Open opportunities for additional revenue for your practice
  • Offer your patients new treatments that may only be available through participation in clinical trials
  • Support the evolution of medicine

You should be familiar with the basics of good clinical practice (GCP). These are the principles and processes that are followed for participant safety and privacy. You will also need a thorough understanding of the principles of conducting clinical trials and the ethical and regulatory requirements. You can learn about GCP and become a certified investigator through the Academy of Pharmaceutical Physicians and Investigators. Certification is not required to become a clinical trial investigator.

The most important factor is that you have a thorough understanding of the commitment needed to participate in a clinical trial. Many investigators find participation a challenging, but very rewarding experience.

You may also want to ask these questions about specific trials:

  • Does this trial fit my patient population?
  • Is there an adequate patient population to meet enrollment goals?
  • Does my practice have the ability to properly store investigational agents?
  • What are the potential pitfalls of this protocol?
  • What would be the compensation to me for participating?
  • Am I, along with my staff, committed to all that will be involved in this trial?

Clinical trials require a fair amount of management and documentation. You will probably want someone to handle that for you, most likely someone who is already on your staff. GCP training will provide tips for incorporating a clinical trial into your day-to-day practice.

If you are selected, you will need to review other forms, including confidentiality agreements, study protocol and an investigator drug brochure (IDB) describing what is known about the drug. Later, your site will be visited by a clinical research associate (CRA) to assess your commitment and your site’s suitability for the trial.

An investigator ensures that a study is conducted according to the:

  • Signed investigator statement
  • Investigational plan
  • Applicable regulations

An investigator is also responsible for:

  • Protecting the rights, safety and welfare of study participants
  • Controlling the drugs under study

An investigator must obtain the informed consent of each study participant to whom the drug is administered.

An investigator administers the drug only to participants under the investigator’s personal supervision or under the supervision of a subinvestigator responsible to the investigator. The investigator must not supply the investigational drug to any person not authorized to receive it.

  • Progress reports: The investigator furnishes all reports to the drug’s sponsor or the sponsor’s representative; the results are collected, evaluated and submitted to regulatory agencies
  • Safety reports: An investigator promptly reports to the sponsor or the sponsor's representative any adverse effect that may reasonably be regarded as caused by, or probably caused by, the drug. If the adverse effect is alarming, the investigator must report the adverse effect immediately
  • Final report: An investigator provides the sponsor or the sponsor’s representative with an adequate report shortly after completion of the investigator’s participation in the study
  • Financial disclosure reports: The investigator provides the sponsor or the sponsor’s representative with sufficient accurate financial information to allow an applicant to submit complete and accurate certification or disclosure statements. The clinical investigator should promptly update this information if any relevant changes occur during the course of the study and for one year following the completion of the study
  • Disposition of drug: An investigator is required to maintain adequate records of the disposition of the drug, including dates, quantity and use by participants. If the study is terminated, suspended, discontinued or completed, the investigator must return the unused supplies of the drug to the sponsor or otherwise provide for disposition of the unused supplies of the drug

If the study is terminated, suspended, discontinued or completed, the investigator must return the unused supplies of the drug to the sponsor, or otherwise provide for disposition of the unused supplies of the drug.

  • Case histories: An investigator is required to prepare and maintain adequate and accurate case histories that record all observations and other data pertinent to the study on each individual who was administered the investigational drug or employed as a control in the study. The case history for each individual shall document that informed consent was obtained prior to participation in the study 
  • Record retention: An investigator retains records for a period of two years following the date a marketing application is approved for the drug for the indication for which it is being investigated; or, if no application is filed or if the application is not approved for such indication, until two years after the study is discontinued

An investigator assures that an IRB is responsible for the initial and continuing review and approval of the proposed clinical study. The investigator also assures that he or she will promptly report to the IRB all changes in the research activity and all unanticipated problems involving risk to participants or others, and that he or she will not make any changes in the research without IRB approval, except where necessary to eliminate apparent immediate hazards to participants.

Created by and for doctors, European Medical Association (EMA) is essentially a service organization.  To improve the quality of health care and medical working conditions in the European community, EMA primarily aims to:

  • Improve information
  • Improve transparency and comparison
  • Encourage collaboration and mobility

EMA’s objectives focus on the improvement of the medical profession in the European context.

  • To act in order to influence health policies according to practicing doctors’ priorities
  • To form a forum of doctors working in the European Union’s medical community
  • To provide its members with information and services that facilitate their professional activity
  • To contribute to the improvement of health care given to patients by helping its members keep abreast of the latest developments
  • To influence the development of health care in Europe by representing its members’ opinions

The U.S. Food and Drug Administration (FDA) is an agency of the U. S. Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the regulation and supervision of food safety, tobacco products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, and medical devices.

An investigator must, upon request from any properly authorized officer or employee of a regulatory agency, at reasonable times, permit access to, and copy and verify any records or reports made by the investigator. The investigator is not required to divulge participant names unless the records of particular individuals require a more detailed study of the cases, or unless there is reason to believe that the records do not represent actual case studies, or do not represent actual results obtained.

In the United States, an institutional review board (IRB) is a group that has been formally designated to review and monitor biomedical research involving human subjects. In accordance with FDA regulations, an IRB has the authority to approve, require modifications in (to secure approval), or disapprove research. This group review serves an important role in the protection of the rights and welfare of participants.
