FDA Announces Availability of the Draft Guidance, “Developing Targeted Therapies in Low-Frequency Molecular Subsets of a Disease”
On December 15, 2017, the US Food & Drug Administration (FDA) announced the availability of the draft guidance for industry entitled “Developing Targeted Therapies in Low-Frequency Molecular Subsets of a Disease”. This draft guidance describes:
- The FDA’s current recommendations on how to group patients with different molecular alterations for eligibility in clinical trials thereby increasing the likelihood of finding viable treatment options for those with less common alterations; and
- General approaches to evaluate the benefits and risks of targeted therapies within a clinically defined disease where some molecular alterations may occur at low frequencies which could lead to more consistent development and approval of targeted therapies for patients who are likely to benefit from them.
Insights into the molecular basis of disease have led to the development of targeted therapies. Targeted therapies are drugs that act on the molecular changes that cause or contribute to a disease (e.g., changes in DNA, RNA, or proteins). Some diseases can be caused by many different molecular changes, some of which can be very uncommon and too infrequent in the disease population to feasibly study in the context of a traditional randomized controlled clinical trial. While drug developers have been able to develop targeted therapies to treat many genetic diseases and cancers, it is often difficult to determine whether or not the drug is effective for certain patients whose disease is caused or affected by uncommon molecular changes. This draft guidance will provide drug developers greater clarity on the FDA’s recommendations for researching and developing new targeted therapies.
