Innate Pharma provides update on lacutamab TELLOMAK trial

Innate Pharma SA (Euronext Paris: IPH – ISIN: FR0010331421; Nasdaq: IPHA) (“Innate” or the “Company”) announced an update regarding its TELLOMAK Phase II trial evaluating the efficacy and safety of lacutamab (IPH4102, a potentially first-in-class anti-KIR3DL2 antibody).  The Company will take the following actions based on ongoing discussions with regulatory authorities regarding a quality issue related to the chemistry, manufacturing and controls (CMC) process: 

• Lacutamab will not be administered to new patients in the TELLOMAK trial until additional feedback is received from the respective regulatory agencies overseeing our clinical trial.
• Until further notice, the Company will continue to treat patients who are currently enrolled in the multi-center trial, except in Italy where the clinical trial has been suspended due to the feedback from Italian regulatory authorities.

This decision is related to issues with the Company’s manufacturing subcontractor, Rentschler Fill Solutions GmbH or “RFS” (now known as Impletio Wirkstoffabfüllung GmbH). RFS has recently withdrawn the Certificate of Conformity of batches they have produced, including the lacutamab batch currently used in the TELLOMAK trial. RFS was granted a Good Manufacturing Practice (GMP) certificate by the Austrian regulatory agency in August 2018 and further confirmed in October 2019.  In parallel, RFS filed for bankruptcy. 

The Company’s utmost priority is to ensure patient safety, and no new safety issues have been reported to date in the TELLOMAK trial. An extensive internal and third-party analysis concluded that there was no element that would affect the CMC quality of the product.

Innate will provide an update once it has received additional feedback from the relevant regulatory agencies. In parallel, the Company is working on resolution of the quality issues related to the CMC matter.
