FDA Warning Letter: Happy Farm Botanicals cited for component testing, stability, and validation failures

FDA states that its March 30 to April 2, 2026, inspection of Happy Farm Botanicals’ OTC drug facility found significant CGMP violations. The firm did not perform specific identity testing on incoming raw materials and components, including APIs, before use; one API lot received only organoleptic testing and was used in finished batches. FDA also found a lapsed supplier requalification and no adequate validation of supplier test analyses. The stability program lacked adequate chemical and microbiological support for labeled expiry periods: accelerated studies lacked controlled humidity records, several timepoints were unavailable, and failing viscosity results in accelerated and long-term studies were not investigated. FDA’s quality unit findings included absent process validation for OTC products, absent cleaning validation for non-dedicated equipment, inadequate investigation and CAPA for recurring gasket seal failures, and inappropriate API content release limits. FDA deemed the firm’s response inadequate and noted that process and cleaning validation commitments from the 2024 inspection remained incomplete. The firm reported plans to cease production of the specified drugs at this facility.

Revised procedure for coordinating GMP inspections of centrally authorised products

Version 3 of the guideline, adopted in April 2026 and entering into force on 10 September 2026, describes EMA coordination of GMP inspections conducted by EEA competent authorities for centrally authorised products. It covers pre-approval inspections, for-cause inspections and routine risk-based re-inspections, including inspection triggers, authority selection, preparation, site contacts and report submission through IRIS. The revision clarifies that, where a Supporting Authority is unnecessary, one Authority may perform both leading and supporting roles. Applicants should identify proposed manufacturing, testing and batch-release sites before submission, and all listed sites should be inspection-ready and compliant with EU or equivalent GMP from submission.

FDA Warning Letter: Jabil sterile manufacturing deficiencies involving fungal contamination and quality oversight

FDA’s February 23 to March 6, 2026, inspection of Pharmaceutics International, Inc., a Jabil company and contract manufacturer of sterile injectables, identified significant finished-pharmaceutical CGMP violations. FDA found inadequate investigations of a sterility failure involving Ustilago spermophora and recurring fungal recoveries in Grade A filling areas, including insufficient root-cause analysis, trend evaluation, and CAPA. The quality unit did not ensure complete documentation of aseptic interventions; one batch record documented 12 interventions although records indicated approximately 200 occurred. FDA also cited inadequate disinfectant efficacy studies and failure to perform process validation after adding a production step. Airflow visualization studies were deficient or omitted following RABS modifications, and some interventions lacked adequate smoke visualization. Environmental monitoring used insufficient sampling techniques and locations. Classified areas also had peeling paint and plastic debris. FDA considered the company’s responses inadequate because they did not sufficiently address contamination sources, systemic investigation weaknesses, quality oversight, or sustainable remediation.

FDA Warning Letter: Unapproved Injectable Peptide Drugs Marketed by Royal Peptides

FDA identified violations during a July 2026 review of Royal Peptides LLC’s website. FDA determined that products marketed as Tirzepatide, Semaglutide, Retatrutide, SS-31 (Elamipretide), PT-141, Tesamorelin, and BIMORELIN were drugs based on claims concerning metabolic regulation, weight loss, mitochondrial function, hormone modulation, recovery, and sexual dysfunction. FDA stated that these products were unapproved new drugs because they were not generally recognized as safe and effective for the labeled uses and had no approved applications in effect. Although product labeling included statements such as “for research use only” and “not for human or animal consumption,” FDA cited website evidence indicating intended human drug use. FDA also noted that the firm marketed bacteriostatic water with a peptide guide and calculator that collectively provided means to prepare an injectable drug for human administration. The letter does not describe a manufacturing-site inspection or identify specific CGMP, laboratory, validation, facility, or quality-system deficiencies.

FDA Warning Letter: Reliance Life Sciences cited for data integrity and aseptic processing deficiencies

FDA’s February 19–27, 2026 inspection of Reliance Life Sciences’ Navi Mumbai drug facility identified significant CGMP violations involving laboratory data, sterile manufacturing, and quality oversight. FDA found environmental monitoring and other microbiology samples recorded as collected and incubated even though plates were absent and analysts confirmed the samples were not collected. LIMS calculations omitted required dilution factors, while electronic integrity-testing files lacked unique names and were overwritten; testing was also not performed for one plant. FDA said these deficiencies created a risk of underreported microbial findings and unreliable batch-release evidence. In aseptic operations, investigators observed operators blocking unidirectional airflow over critical locations and not discarding potentially compromised vials. FDA also observed deteriorated or damaged manufacturing areas or components, excess sealant near HEPA filters, nonsterile wipes used for cleaning, and standing water and staining near pipelines. FDA deemed the firm’s responses insufficient, citing incomplete remediation detail, traceability, oversight, and timelines. The company agreed to recall all sterile drugs and suspend U.S.-market production; FDA later placed its drugs on Import Alert 66-40.

FDA Warning Letter: PReye cited for unsuitable aseptic processing and inadequate quality systems

FDA states that its March 17–19, 2026, inspection of PReye’s drug manufacturing facility found significant finished-pharmaceutical CGMP violations. The firm manually filled multiple drug products from bulk liquid using a small flow hood on an office desk. FDA observed that the hood was neither certified nor qualified and was located in unclassified office space without HEPA filtration. FDA stated that these conditions lacked appropriate facilities, equipment, and process controls to protect products from microbiological contamination. FDA also found no quality unit function or written procedures defining its responsibilities. Basic procedures were absent, including complaint review, supplier qualification, release testing, change management, cleaning, disinfection, and deviation handling. FDA further reported missing batch numbers for sterile ophthalmic products manufactured since 2024, impairing traceability. The firm committed to cease U.S. manufacturing and distribution of PReye Vitamin SEE; it later voluntarily recalled the product because sterility testing had not been performed.

FDA Warning Letter: Insanitary API Manufacturing, Incomplete Laboratory Data, and Weak Quality Oversight

FDA states that its April 13 to 17, 2026 inspection of Shoolin Pharma Chem LLP found APIs prepared, packed, or held under insanitary conditions and identified significant API CGMP violations. Investigators observed layered unidentified residues, chemical residues and stains on walls, floors, equipment, and product-contact areas; corroded or apparently rusted surfaces; leaking lines; improperly stored transfer lines; and an employee wearing open-toed sandals near open equipment during production. Nondedicated equipment was used for multiple APIs. FDA also found inadequate written cleaning and maintenance procedures, no swab or rinse cleaning verification, and insufficient cleaning validation remediation. The firm could not provide raw data supporting certificate-of-analysis results, while contract-laboratory results were reported on company letterhead without identifying the original laboratory. Stability chambers were powered off or outside temperature or humidity conditions, supporting records were unavailable, and tadalafil samples were missing. FDA further cited inadequate quality-unit oversight of impurity risks, contract laboratories, process validation, equipment calibration, materials testing, and annual product reviews. The firm recalled all APIs distributed in the U.S., and FDA placed its drugs on Import Alert 66-40.

FDA Warning Letter: Fresenius cited for leaking dialysis solution bags and inadequate visual inspection controls

FDA inspected Fresenius USA Manufacturing’s Ogden, Utah drug facility from March 2-6, 2026, and cited significant CGMP violations involving complaint investigations, CAPA, process controls, and visual inspection of sterile injectable products. For Delflex Peritoneal Dialysis Solution, an August 2025 investigation covered 35 complaints involving approximately 156 leaking bags from multiple batches and attributed holes to printing. FDA stated that the firm assigned the lowest severity despite its matrix identifying peritonitis as a potential harm at the highest severity, did not recall then, and inadequately investigated risk and implemented CAPA. After inspection, reexamination found perforations without substantial fluid in the overwrap; the firm reassessed risk and recalled affected lots on April 6, 2026 for lack of assurance of sterility. FDA found the response still lacked sufficient CAPA to improve leak detection. FDA also found personnel qualification for visual particulate inspection inadequate because the kit was not adequately representative and records lacked sufficient detail, and said the response did not demonstrate reliable detection at an appropriate level.

International regulators assess recombinant endotoxins testing protocol

FDA states that, through the International Coalition of Medicines Regulatory Authorities Collaborative Assessment Pilot, it and regulators from Australia, Canada, Japan, Switzerland, and the European Medicines Agency jointly assessed a recombinant endotoxins testing approach for biological products. The method is an alternative to the horseshoe crab blood-dependent Limulus Amebocyte Lysate test. The submission used a Post-Approval Change Management Protocol covering several biological products across multiple therapy areas. The European Medicines Agency led the review, and the PACMP was approved in June 2026, with participating authorities reaching aligned decisions within days. FDA says the pilot coordinates questions and reviews while preserving independent decisions, aiming to improve consistency, reduce duplication, and support timely access.
