Second Submission Anticipated Around Q3 2020

PORTLAND, Maine, Aug. 29, 2019 — ImmuCell Corporation (Nasdaq: ICCC) (“ImmuCell” or the “Company”) – a growing animal health company that develops, manufactures and markets scientifically-proven and practical products that improve the health and productivity of dairy and beef cattle – today announced that it has received a response from the U.S. Food and Drug Administration (FDA) to its first phased Nisin Drug Substance submission of the Chemistry, Manufacturing and Controls (CMC) Technical Section for Re-Tain™, the Company’s novel treatment in development for subclinical mastitis in lactating dairy cows.

Under the FDA’s phased submission process, Phase 1 concerns the Nisin Drug Substance, and Phase 2 concerns the Re-Tain™ Drug Product (formulated Nisin filled in a syringe). As part of the phased submission process, the FDA issued a Technical Section Incomplete Letter with various requests and queries in addition to referring to the fact that the second phased submission has yet to be submitted. This process allows a sponsor to respond to identified deficiencies from the first phased submission at the time of the second phased submission. The second phased Drug Substance and Drug Product CMC Technical Section submission is expected to be made around the third quarter of 2020. In addition to responding to comments raised by the FDA regarding the first phased submission, one of the key components of the second phased submission is demonstrating stability of the product over time using the commercial process and the commercial syringe.

“Having reviewed the comments from the FDA, we see no road blocks on our path to FDA approval for Re-Tain™,” commented Michael F. Brigham, President and CEO. “We believe we can respond effectively to the FDA’s comments without significant additional cost or time delays.”

Having previously achieved four different Technical Section Complete Letters from the FDA, approval of the CMC Technical Section is the fifth and final significant step required before Re-Tain™ product sales can be initiated in the U.S.
