Is it Possible to Gain Regulatory Approval Following a Single-Arm Study?

In this case study example - yes.

Veristat developed a thorough regulatory submission strategy and novel efficacy endpoint for the treatment of an ultra-rare and aggressive hematologic malignancy that led to FDA and EMA approval following a single-arm phase I/II study.

A small biotech company engaged Veristat early in clinical development for help with a novel biologic being tested for treatment of an ultra-rare and aggressive hematologic malignancy with no available effective therapies.

The biologic was tested in a single-arm study due to the ultra-rarity of the condition and that there were no other approved treatment options. Treatments for other hematologic malignancies were used but did not provide durable responses. After initial dose escalation and an expansion cohort, it became clear that the novel product led to an improved response rate and a more durable response that could make significant differences in the patient’s quality of life.


Well-planned strategy leads to marketing application success

Using the results of a single-arm Phase I/II study, Veristat and the sponsor company collaborated to present a thorough, well-planned strategy for demonstrating the benefits and risks of the targeted therapy in this patient population to regulatory authorities. Based on Veristat’s significant experience, the sponsor engaged our team for strategic consulting, statistical and programmatic support, and medical writing to plan and execute the marketing application process, eventually leading to both FDA and EMA approval.
