Explanation
This temporary halt was first notified to the CCMO under the CTD 24Nov2022, the details submitted at the time were:

The Netherlands Cancer Institute (NKI), the single site conducting the above referenced study, was instructed to pause recruitment by the Sponsor on Friday 11 November 2022. The voluntary decision to pause recruitment and pre-screening was taken based on an interim assessment of the study which observed a low success rate of TCR identification for the subjects that have been pre-screened to date. Neogene believes the observed low success rate is related to the intrinsic variability of tumour biospecimens collected from the subjects pre-screened which has impacted the downstream steps of biospecimen processing and, subsequently, resulted in inadequate TCR identification. These findings do not constitute a safety concern for the subjects whose biospecimens were successfully processed and progressed to TCR selection.
No subjects have yet received treatment with NT-125. For the subjects already recruited that have undergone tumour biospecimen collection and who are currently undergoing TCR identification, the Sponsor intends for these subjects to remain in the study, continue the process, and receive the investigational treatment if TCRs are successfully identified as per the approved protocol and procedures.
Neogene continues to investigate the issues and plans to further refine the TCR identification and selection process with the intent to enhance the success rate; all corrective actions and future process changes will be promptly communicated to CCMO and VWS, prior to resuming recruitment and pre-screening.
Follow-up measures
Currently there is one participant in follow up. No more participants are planned to be dosed or recruited whilst the temporary halt is in force.
