CHMP recommends revocation of Tavneos (avacopan), EMA will act on historical GCP failures in pivotal trial data
CHMP recommended revoking Tavneos's EU marketing authorisation on 26 June 2026, a drug on the market since 2022, after finding the pivotal ADVOCATE trial was run in breach of Good Clinical Practice and that its data, in EMA's own words, "were found to be incorrect and misleading and could no longer be relied upon for demonstrating Tavneos' effectiveness."
Why it matters
CHMP opened its review of Tavneos to assess new information questioning the data integrity of the pivotal ADVOCATE trial, not because of a new safety signal or a post-marketing failure. On 26 June 2026, EMA said the study data submitted with the original application "were found to be incorrect and misleading and could no longer be relied upon for demonstrating Tavneos' effectiveness."
What to check
Pull your pivotal trial audit history this week. For every EU marketing authorisation, check whether the pivotal dataset carried unresolved GCP findings, monitoring deviations, or source data discrepancies, even ones closed out before approval. CHMP's Tavneos review was triggered by exactly that kind of retrospective question, not by a new safety signal.

CHMP rejects three orphan-designated therapies in June 2026 plenary, unmet need does not offset unconvincing benefit-risk
CHMP adopted negative opinions for three orphan-designated medicines in its 22-25 June 2026 plenary, a tumour-infiltrating lymphocyte therapy for melanoma, a pooled faecal microbiota product for graft-versus-host disease, and narsoplimab for transplant-associated thrombotic microangiopathy, and the common thread across three unrelated therapeutic areas is manufacturing and endpoint data that orphan status didn't rescue.
Why it matters
The Advanced Therapy Medicinal Product field has operated on a working assumption that CHMP exercises flexibility on evidence certainty for serious unmet needs with no alternatives. Manufacturing heterogeneity, batch-to-batch variability inherent in autologous cell therapies or live microbiome products, is not something CHMP is discounting at the marketing authorisation stage. The same session's Daybu reversal is the counterpoint: following re-examination, CHMP granted trofinetide a marketing authorisation for Rett syndrome, restricted to patients aged five and older, a narrower label backed by refined data, not resubmission of the same package.
What to check
When EMA publishes the European Public Assessment Reports for the three rejected medicines, map the specific rejection grounds, manufacturing consistency, endpoint variability, benefit-risk weighting, against your own ATMP development programme. Treat the Daybu re-examination outcome as a process precedent: if you have a negative CHMP opinion, re-examination with a refined indication and updated analysis is a viable path.

Ph. Eur. 5.1.10 revised, rFC formally accepted as endotoxin test alternative; EDQM comment deadline 30 June 2026
EDQM's Pharmeuropa 38.2 draft revises Ph. Eur. 5.1.10 to add recombinant Factor C as an accepted alternative alongside the existing Limulus Amebocyte Lysate test, not a replacement for it, and reinstates Section 11 to cover recombinant cascade reagent methods, the public consultation closes 30 June 2026, EDQM's last formal comment window before this becomes the compendial standard for rFC method validation.
Why it matters
EDQM frames the revision as part of the 3Rs push to reduce animal-derived reagents in testing. That text will set the compendial standard for method validation, equivalence demonstration, and change control documentation for every lab using or transitioning to rFC. After 30 June, the next chance to shape the text through a formal comment cycle is years away.
What to check
Pull the Pharmeuropa 38.2 draft of Chapter 5.1.10 from the EDQM website and compare it against your current rFC method SOP and change control documentation. EDQM's own summary of the revision: it "has been revised to add the method using recombinant factor C (rFC) and to clarify which specific provisions apply only when using amoebocyte lysate," and Section 11 "has been reinstated and now includes a new reference to the method using recombinant cascade reagents (rCRs)." Flag any gap between that text and your current validation approach before the 30 June 2026 comment deadline.
