Withdrawal – need for a consensus

Article No. 457

Yet another article about the outcome of withdrawal of eculizumab treatment has appeared. It is not about a controlled trial of patients selected to test withdrawal of treatment. This one is based on what was observed by the Alexion aHUS Registry, ( Full article can be seen HERE ).   It is possible that some of the patients observed may have participated in national treatment withdrawal trials too.

Within the Registry there are aHUS patients who have withdrawn from eculizumab treatment by their doctors. The Registry investigators looked at what happened to 151 such aHUS patients who had been successfully treated  with eculizumab. 118 had no TMA relapse after withdrawal at the time of publication.

Of the 33 who did relapse the investigators found that

1- they had a history of extra renal manifestations prior to treatment ;

2- pathogenic variants ( mutations)

3-family history of HUS

All of which adds to the risk analysis considerations required prior to an informed decision to successfully withdraw from treatment. Global Action are not aware of  items 1 and 3.  being cited before, whereas there is already more detailed information about item 2.

There were several reports on eculizumab withdrawal published late last year along, with case studies, so the time is coming when all this current insight should be brought together in something that can be used by any treating clinician anywhere to talk to their  aHUS patient about.

It is as important to use  such evidence  to explain to patients why treatment is not going to be withdrawn as it is to counsel those patients who are most likely no longer needing  treatment and would be able to  have that burden lifted.

It is particularly important for those who when all things are considered are at the margin of such a decision,

For the latter, it is very important that the monitoring process  following withdrawal is safe, sustainable and proportional over time; reflecting best practice.

Any such consensus advice will of course need updating as more is known about known predictors and probabilities.

Indeed there may be other predictors not yet  found e.g whether higher levels of ADAMTS13 at first  presentation, which might predict plasma exchange treatment success and withdrawal, might be a predictor of complement inhibitor withdrawal too.

In fact could anything be learned from all those patients who have gone into remission, whether or not they have been treated by eculizumab. What is it about them?

So whilst there is no longer a paucity of information, what there is has not been suitably collated to inform aHUS patients.

There is growing evidence that withdrawal of eculizumab ( and thus ravulizumab)  treatment for aHUS can be successful. It is no longer regarded as a life time treatment for all. Though it will be for some.  Withdrawal can lead to relapse. Sometimes that  could have been predicted. Some times it might reveal another factor which adds to the “risk assessment matrix”.

The French “StopECU” study intends to produce an algorithm which can predict a withdrawal outcome. It is needed very much.

The aHUS Patient Research Agenda  topic question is  “Can a complement inhibitor be stopped safely when not needed by some aHUS patients and what makes them different?

The answer is “YES” and more is being discovered on when and why it may not be needed because of the differences in  aHUS patients, and how to do it safely.

Done safely based on evidence that a patient is suitable to withdraw, and is also part of the decision making to  release them from a treatment burden with more assurance.

Health policy makers who are put off by the cost of eculizumab treatment today, could be persuaded that  collectively aHUS patient complement inhibitor treatment in their country would be more cost effective than has previously been thought.

So more patients, currently denied treatment, could benefit.

Consensus will make that possible.
