aHUS Trials Watch 12a (crovalimab)

Article No. 445

13 July 2021

Hoffmann Roche has announced its pediatric trial of crovalimab for aHUS. It is featured on the ClinicalTrials.Gov website and can be found at this link HERE.

Although its status is currently “not yet recruiting” the plan is to study the effectiveness and safety of the drug on 35 children, beginning in October this year. The estimated completion date is December 2025.

There will be three study arms. Firstly those who have not been treated with a complement inhibitor before i.e. naive , those who choose to switch from eculizumab treatment and finally those have been pre treated but for whom eculizumab did not work or who have withdrawn from treatment

27 hospital locations in 11 countries have been listed where recruitment will take place including

The usual study outcomes apply , the prime being  a complete TMA response by week 25  in those naive to complement inhibitor treatment. There are 23 secondary outcome measures at 25 weeks and up to 8 years. Nothing which asks the patient their views on the experience and perception  of the method and interval of treatment delivery. This drug has to be self injected, which is  novel to aHUS treatment but common in diabetes treatment.

The usual inclusion/exclusion criteria apply.

Four or eight years of data will not be needed to make an application for marketing approval of crovalimab but 25 weeks data will be needed from the last patient recruited.

Then work can be begin on revealing the outcomes in clinical publications which will take time to do but it is unlikely to be before 2023. If there is a positive outcome further time will be taken in going through licensing processes, e.g. FDA ,before health policy makers get to rule on funding it for patients,
