The European Medicines Agency (EMA) announced on Nov. 10, 2023 that its Committee for Medicinal Products for Human Use (CHMP) has recommended approval of eight new medicines at its latest meeting. The medicines, three of which were designated as orphan medicines, include treatments for generalized myasthenia gravis, glioma, neovascular age-related macular degeneration, and more.

Omjjara (momelotinib), an orphan medicine, was recommended for treating the rare blood cancer, myelofibrosis, which affects the bone marrow.Another orphan drug, Rystiggo (rozanolixizumab), was recommended for approval to treat generalized myasthenia gravis, which is a chronic autoimmune neuromuscular condition. The third orphan drug, Spexotras (trametinib), was given a positive opinion for treating glioma, a brain tumor that develops in glial cells, in pediatric patients aged one year and older.

Two biosimilars and two generic drugs were also recommended for approval. The biosimilar Rimmyrah (ranibizumab) was recommended for treating the retinal macular disease, neovascular age-related macular degeneration. The second biosimilar, Uzpruvo (ustekinumab), was recommended to treat plaque psoriasis, psoriatic arthritis, and Crohn’s disease. The generic drugs that received a positive CHMP opinion include Azacitidine Kabi (azacitidine), for the treatment of myelodysplastic syndromes, chronic myelomonocytic leukemia, and acute myeloid leukemia; and Naveruclif (paclitaxel), which treats metastatic breast cancer, metastatic adenocarcinoma of the pancreas, and non-small cell lung cancer.

CHMP also granted conditional marketing authorization after a re-examination to Krazati (adagrasib) for the treatment of advanced non-small cell lung cancer with a G12C mutation in the KRAS gene in adults whose disease has worsened after at least one systemic treatment. The committee also extended recommendations for nine previously authorized medicines: Ayvakyt (avapritinib), Evkeeza (evinacumab-dgnb), Fluad Tetra (influenza vaccine [surface antigen, inactivated]), Jardiance (empagliflozin), Keytruda (pembrolizumab), Mounjaro (tirzepatide), NexoBrid (anacaulase-bcdb), Talzenna (talazoparib), and Veltassa (patiromer).

Two applications for recommendation were withdrawn. Vijoice (alpelisib), an orphan drug, which would have been for the treatment of PIK3CA-related overgrowth spectrum, was withdrawn. Bylvay (odevixibat), also an orphan drug, had an application for extension of use to include treatment of cholestatic pruritus in Alagille syndrome in patients aged six months or older withdrawn.

Recommended medicines include treatments for generalized myasthenia gravis, glioma, neovascular age-related macular degeneration, and more.

EMA Recommends Rare Blood Cancer Treatment and Seven Other Medicines

The European Medicines Agency (EMA) announced on Nov. 8, 2023 that the Heads of Medicines Agencies (HMA), the European Commission, and EMA have published electronic product information (ePI) for selected medicines that have been harmonized across the European Union. The published ePIs are part of a one-year pilot program, under the Pharmaceutical Strategy for Europe, for the transition of information to an electronic system. Companies participating in the program create and submit the ePI as part of a regulatory application. The published ePIs include medicines that were evaluated by EMA or national authorities in Denmark, the Netherlands, Spain, and Sweden. The pilot program includes 25 medicines and will conclude in July 2024.

A Product Lifecycle Management Portal is available to view the ePIs in English for centrally approved drugs and in the local language of nationally approved medicines. ePI data can also be accessed via a public application programming interface.

According to EMA, medicine product information is provided for each authorized drug in the EU and includes a summary of characteristics, labeling, and a package leaflet. The information can also be found on EU regulator websites. “Digital platforms open new possibilities to share this information electronically, keep it constantly updated and make it more accessible to end users such as healthcare professionals and patients,” EMA stated in a press release.

“These ePIs were created following the EU ePI Common Standard adopted by the European medicines regulatory network to provide a consistent structure throughout all Member States and ensure the information works across different e-health platforms. This should facilitate the use of product information to meet individual needs and access requirements. Future developments could include functionalities such as automatic update notifications, access to supportive videos or audio content and online adverse-reaction reporting tools,” the agency stated in the release.

Electronic product information for selected human medicines that have been harmonized across the European Union have been published for the first time.

Europe Publishes Electronic Product Information for Selected Medicines

On Nov. 7, 2023, FDA issued final guidance that includes recommendations for reporting post-approval changes of some common changes to container closure system (CCS) components consisting of glass vials and stoppers for approved sterile drug products and biologics. The recommendations apply to approved new drug applications (NDAs), biologics license applications (BLAs), and abbreviated new drug applications (ANDAs). Pathways available to application holders to obtain feedback from FDA are also presented. Risk-based tools for implementation of changes to CCSs consisting of glass vials and stoppers are provided. This guidance does not apply to CCS types other than glass vials and stoppers.

According to FDA, many COVID-19 products use glass vials and stoppers as their CCS, and the supply of these products may be constrained. Manufacturers, therefore, may need to update approved applications to reflect changes made to CCS components to fill demand. The agency will consider risk-based approaches to implementation of chemistry, manufacturing, and controls (CMC) changes to a CCS so that supply of products is not impeded.

The guidance details common changes related to glass vials and stoppers and provides information on tools that can facilitate changes to CCS components. “FDA may expedite the assessment of a supplement or determine that a different reporting category is appropriate, taking into account public health priorities and the applicant’s rationale and associated risk assessment and mitigation strategy for the proposed change. Should a different reporting category be determined to be appropriate, FDA will notify the applicant and convey its rationale for the determination,” the agency states in the document.

The policy remains in effect until Aug. 7, 2024 unless a revised final guidance is published before then. More information can be found in the

On Nov. 3, 2023, the European Commission announced it was launching a selection procedure for experts looking to join the European Medicines Agency’s (EMA’s) independent Pharmacovigilance Risk Assessment Committee (PRAC) and Committee for Orphan Medicinal Products (COMP). 

The six PRAC experts will be appointed to a three-year term that starts on July 2, 2024 and will have an active role in supervision of medicines in Europe. Members of PRAC are independent scientific experts and are expected to actively contribute to PRAC discussions.

COMP is looking for three new committee members to represent patients’ organizations for a three-year term that begins July 1, 2024. Members participate in COMP procedures and attend monthly meetings. They also contribute to scientific discussions, examine documents, and speak for their target group. COMP members are also members of EMA’s Pharmacovigilance Risk Assessment Committee, Paediatric Committee, and Committee for Advanced Therapies.

“The COMP has a strong tradition of involving patient representatives in its work. Its main task is to examine applications sent by companies and decide whether their medicines can be designated as 'orphan'. An orphan medicine is used in the diagnosis, prevention, or treatment of a life-threatening or chronically debilitating condition that is rare, which means it affects no more than five in 10,000 people in the European Union (EU). The role of a patient organization representative in the COMP is to give a voice to patients and ensure their needs are taken into account in the Committee's decision-making process. Although a medical background is not required, candidates may benefit from a sound knowledge of medical and, to a certain extent, regulatory issues related to medicines in the EU,” the agency stated in a press release.

Submissions for applications for either commission are due Dec. 7, 2023 at 12:00 CET. Current members may also re-apply.

The EC is calling for interested parties for their safety and orphan drug committees.
