Nanomerics today announced end of dosing with all volunteers completing the full schedule and without moderate or severe adverse events reported:
Nanomerics reported that it had completed 28 consecutive days of administration in its OC134 Phase I trial – the SUNLIGHT trial. Dosing twice daily (12 h apart) of the healthy study participants with MET eye drops and OC134 eye drops commenced in December 2024 and was completed in January 2025. All volunteers (n=10) completed the dosing schedule, with no drop outs and volunteers will report for follow up assessments in February 2025.
There were no adverse events of moderate or severe severity reported during the clinical phase of the trial and there were no clinically significant individual changes from baseline or notable trends in safety assessments including safety bloods, vital signs, eye examination, 12 lead ECGs and urine analysis.
Single topical administration of MET and OC134 eye drops on 56 consecutive occasions were well tolerated by healthy volunteers under the condition of trial. Approval was granted recently for the OC134 and MET tolerability study by the UK Medicinal and Healthcare Products Regulatory Agency (MHRA) and the study was conducted by Quotient Sciences at its Nottingham, UK Phase I study site according to Good Clinical Practice guidelines.
OC134 is an eye drop medicine candidate indicated for the topical treatment of moderate to severe allergic conjunctivitis, a condition for which a suitable non-steroidal topical ocular treatment, does not currently exist.

OC134 is powered by Nanomerics’ Molecular Envelope Technology (MET), a non-irritant ocular penetration enhancer. Nanomerics’ MET is a platform ocular penetration enhancer, that has been shown in preclinical studies to increase the penetration of active pharmaceutical ingredients (APIs) into the front of the eye; increasing ocular deposition up to 18-fold, when compared to conventional formulations. In preclinical studies, Nanomerics’ MET also demonstrated the delivery of APIs to the retina from eye drops. Nanomerics has a pipeline of ocular assets that may now be tested in clinical studies and ultimately launched for the benefit of patients. Nanomerics’ MET is now a clinical stage ocular excipient.
Professor Andreas G. Schätzlein, Nanomerics’ Chief Executive Officer said,
“We are pleased that Nanomerics has completed the dosing phase of its first clinical study – the SUNLIGHT trial - with Nanomerics’ Molecular Envelope Technology (MET) powered eye drops. This is an important step which will now enable us to move forward our ocular pipeline for later stage clinical testing. We are indebted to our clinical trials partner – Quotient Sciences – for working with us on this Good Clinical Practice trial.”
Dr Nand Singh, Medical Director at Quotient Sciences commented,
“We are pleased that the First-In-Human trial has completed the clinical phase of the study at our Nottingham, UK clinic for Nanomerics’ OC134 Phase 1 SUNLIGHT trial. This trial marks a significant milestone in the development of a new therapeutic approach aimed at developing advanced treatments for moderate to severe allergic conjunctivitis.”

Using technology to increase access to youth mental health support may offer a practical way for young people to reach guidance, safe-spaces, and early help without feeling overwhelmed by traditional systems. Digital platforms, helplines, and apps could give them a chance to seek support privately, connect with trained listeners-orexplore resources that might ease their emotional load. This gentle shift toward tech-based support may encourage youth to open-up at their own pace, especially when in-person help feels too heavy to approach.
