Zenzi Pharmaceutical Industries Pvt. Ltd.

Your facility is registered with the United States Food and Drug Administration (FDA or Agency) as a manufacturer of prescription drug products. A review of records showed that you are a contract manufacturing facility of prescription drug product that was delivered into the United States. On October 29, 2024, the FDA sent an electronic request for records and other information pursuant to section 704(a)(4) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 374(a)(4), to the contact e-mail provided in your customer’s contract manufacturing agreement. This request went unanswered. The Agency sent a follow-up written request for such records and other information on November 7, 2024. Delivery to you was confirmed by the shipper. On November 13, 2024, your Vice President of Quality responded via e-mail stating your firm does not supply (b)(4) ((b)(4) Injection USP) labeled with the address of (b)(4) (your customer). This is in contradiction to records provided by your customer. A third request was sent via e-mail on November 15, 2024. You failed to respond to these attempted communications or otherwise provide the requested records or other information. Pursuant to section 704(a)(4), FDA’s request and follow-up communications included a sufficient and clear description of the records sought.

A contract manufacturing agreement provided by the (b)(4) owner and other records show that you are the manufacturer of (b)(4), which was shipped to the United States. These records include your registration file, your certificate of analysis, and a batch production record for (b)(4).

It is a prohibited act under section 301(e) of the FD&C Act (21 U.S.C. 331(e)) to refuse to permit access to or copying of any record as required by section 704(a). Because your firm failed to respond to the section 704(a)(4) records requests and associated communication attempts, we have no indication of the level of quality assurance for drugs listed as manufactured at your facility.

FDA placed all drugs and drug products manufactured by your firm on Import Alert 66-79 on February 12, 2025.

Until FDA is able to confirm compliance with Current Good Manufacturing Practice (CGMP) and other applicable requirements, we may withhold approval of any new applications or supplements listing your firm as a drug manufacturer. In addition, shipments of articles manufactured at Zenzi Pharmaceutical Industries Pvt. Ltd., FEI 3032916295, located at Plot No. H-53, Additional Murbad M.I.D.C., Kudavali, Dist. Thane, Maharashtra, India, into the United States that appear to be adulterated or misbranded are subject to being detained or refused admission pursuant to section 801(a)(3) of the FD&C Act, 21 U.S.C. 381(a)(3).
