Rare disease clinical trials factsheet

It is estimated that 475 million people worldwide are affected by a rare disease.

Drug development for rare diseases involves significant challenges above and beyond those encountered in large trials for more common diseases. Partnering with Cromos Pharma means working with an international CRO with a strong track record in innovative trial design, exceptional multi-country patient recruitment and proven regulatory expertise.

DEFINING RARE DISEASES:

The definition of rare diseases varies according to country.

In the US, a disease is considered rare and eligible to qualify for Orphan Designation if it affects less than 200,000 people in the United States. The National Human Genome Research Institute states that over 6,800 rare diseases affect a total of 25-30 million Americans.

In the EU, a rare disease is defined as a condition that affects no more than 1 person in 2,000. In the EU it is estimated that 5,000-8,000 distinct rare diseases affect 6-8% of the EU population i.e., between 27 and 36 million people.

Clinical trials involving rare diseases involve a unique set of scientific and operational challenges:

• Limited pool of eligible patients
• Wide geographical spread of study subjects and Investigators
• Large heterogeneity in patient populations with different phenotypes and various disease pathophysiology
• Lack of preceding clinical trials to establish a baseline standard for study execution
• Large heterogeneity in treatment effects
• Uncertainty in regulatory practice and various regulatory requirements in each country of operations

PATIENTS FIRST

The welfare of our patients is our first priority. We make sure that they have a direct line of communication to both the investigators and to our research team.
