Efficacy & Safety
The Power of the Tri-Offense
Anktiva is an interleukin-15 (IL-15) receptor agonist, which is a type of immunotherapy that causes natural killer and T cells to increase in numbers and become more active without activating immunosuppressive T reg cells.1
The efficacy outcome measures for the QUILT-3.032 study were complete response (CR) at any time, defined as negative cystoscopy and urine cytology, and duration of response.1
QUILT-3.032 is a multicenter, single-arm study in adults with BCG-unresponsive high-risk NMIBC with CIS ± Ta/T1 papillary disease. Efficacy was evaluated in 77 adults (label), with updated follow-up in 100 patients. Patients received nogapendekin alfa inbakicept-pmln 400 mcg plus BCG weekly for 6 weeks, with re-induction permitted at month 3. The primary endpoint was complete response.1,2
