Over the course of the last ten months, the Company has developed a solid plan to address the previously outlined chemistry, manufacturing, and control (CMC) issues cited in the FDA’s July 2021 letter regarding the clinical hold on the Company’s INDs. Based on the unanimous advice from independent regulatory experts, the Company has determined that it is not necessary to proceed with the previously contemplated Type A meeting with the FDA to further address the CMC issues and instead will move forward with a submission of an amended IND for Procel directly to the FDA during the second half of this year.
The Company also announces ongoing progress toward the implementation of a current good manufacturing practice (cGMP) mammalian master cell bank (mMCB), which will provide a GMP-grade retroviral vector for gamma delta T (GDT) cell engineering. A cGMP mammalian master cell bank is a significant step forward in the Company’s clinical pathway and would address a key issue identified by the FDA in the clinical hold letter.
"We are very pleased to share these significant regulatory updates, reflecting the progress we have been making as a Company. In addition, progress toward establishing the master cell bank will enable us to create the GMP-grade retroviral vector for gamma delta cell engineering – a cornerstone of our clinical program" stated Pietro Bersani, Kiromic BioPharma’s Chief Executive Officer. "These achievements demonstrate our team’s execution efforts toward our goal of beginning the activation of the clinical trial for our first oncology cell therapy candidate Procel by the end of the fourth quarter of 2022."
