Newron Pharmaceuticals — Constructive FDA meeting

Newron has announced a constructive Type A meeting with the FDA regarding the enrolment hold affecting US sites in the Phase III ENIGMA-TRS 2 study. The discussion focused on information previously submitted by the company and the changes required by the FDA before it will consider allowing enrolment to resume. Importantly, management indicated that both parties discussed potential actions towards resolving the outstanding issues, with Newron now planning to propose protocol changes agreed with the agency. While the timing of US enrolment resumption remains uncertain, we view this update as encouraging, as it shows continued regulatory engagement, and provides a clearer pathway towards resolving the hold. Meanwhile, the broader ENIGMA-TRS programme is progressing, with ENIGMA-TRS 1 actively enrolling patients globally ahead of its planned Q426 primary endpoint readout.

The FDA placed a hold on enrolment at US sites in ENIGMA-TRS 2 in April 2026 following the sudden death of a participant at a non-US clinical site. The investigator concluded that the event was unrelated to evenamide treatment, and the independent international safety monitoring board reviewed the case and recommended that both ENIGMA-TRS studies continue as designed. The latest announcement suggests that discussions have now progressed from information gathering, towards identifying specific actions that could enable the FDA to lift the hold.

We highlight that these events have not affected ENIGMA-TRS 1, which remains the lead international registrational study. The trial is currently enrolling patients across 15 countries and remains on track to report its primary 12-week efficacy and safety assessment in Q426. ENIGMA-TRS 2 includes sites outside the US, supporting Newron's strategy of advancing a global Phase III programme for evenamide in treatment-resistant schizophrenia.

Overall, we believe the announcement should be viewed as an incremental but positive regulatory update. Although there is still no definitive timeline for restarting US enrolment in ENIGMA-TRS 2, the constructive nature of the meeting and Newron's agreement with the FDA on the next steps suggest that the review process is progressing. In our view, the key investment focus remains the continued execution of ENIGMA-TRS 1 and the anticipated Q426 readout, which represents the most significant near-term catalyst for the programme.

Topps Tiles — Macroeconomic uncertainty, extreme weather

Topps Tiles’ Q326 trading update shows the uncertain macroeconomic environment has led to increased demand for lower priced, and therefore lower margin, products, which provides a headwind to profit growth. This has been compounded by the recent extreme temperatures affecting demand from professional and trade customers in the second half of the period. While a normalisation of temperatures will help the company to recover some of the lost trading, the margin pressures remain, and therefore management downgrades its adjusted PBT guidance by c 30% versus our prior estimate. While the downgrade in guidance for the year is disappointing, it is reassuring the strategy initiatives continue to drive market outperformance.
