IPH4102 is an anti-KIR3DL2 antibody being developed by Innate Pharma as a treatment for T-cell lymphomas.

The FDA’s fast track program is designed to expedite the review of products that are intended to treat serious conditions and have the potential to address unmet medical needs.

The fast track designation for IPH4102 is based on preliminary results from a phase 1 study (NCT02593045) of patients with advanced cutaneous T-cell lymphoma.

Data on 35 Sézary patients in this trial were presented at the 2018 annual meeting of the American Society of Hematology (Blood. 2018;132:684). The patients had a median age of 70 (range, 31-90), and they had received a median of 2 (range, 1-9) prior systemic therapies.


As of Oct. 15, 2018, the overall response rate was 42.9%, with 2 complete responses and 13 partial responses. The median duration of response was 13.8 months, and the median progression-free survival was 11.7 months.

Treatment-related adverse events (AEs) included asthenia (n = 5), lymphopenia (n = 5), fatigue (n = 3), pyrexia (n = 3), arthralgia (n = 2), and diarrhea (n = 1). The only grade 3/4 treatment-related AE was lymphopenia (n = 2).

Four patients experienced six grade 3 or higher AEs that were possibly related to treatment—grade 5 hepatitis (n = 1), grade 4 sepsis (n = 1), grade 3 lymphopenia (n = 3), and grade 3 hypotension (n = 1).

Based on these results, Innate Pharma is planning a phase 2 trial of IPH4102, which is expected to begin in the first half of this year.
