All the patients provided written informed consent and
a consent to continue participation was obtained from patients who had a
confirmed relapse or progression of disability. The study was approved by the
local ethics committees and was conducted in accordance with the International
Conference on Harmonisation guidelines for Good Clinical Practice and the
principles of the Declaration of Helsinki (Ludwig Kappos, 2015).

Ethics

 

Daclizumab is a
second-line medication for MS patients; it can cause an increase in liver enzymes.
For this reason a blood sample will be taken every month during treatment and
four months after treatment. If a patient has an active infection, the
treatment should be postponed or interrupted till the infection disappears. A
group of patients using daclizumab will be forced to stop the treatment if the
side effects get too severe (MS Centrum Amsterdam , 2017) (Zorginstituut Nederland , 2017).

Since February 2017,
daclizumab (Zinbryta) became available for patients with RRMS; it is given to
patients that still have a lot of relapses or have worsening attacks even
though they take the available first-line medications like interferon
?.

Consequences and Implications

 

The enhanced efficacy was accompanied by an increased
frequency of adverse events, such that the net clinical benefit will need to be
carefully considered by patients and their providers (Ludwig
Kappos, 2015).

Daclizumab HYP demonstrated superior efficacy
regarding ARR and brain lesions versus intramuscular interferon ?-1a in relapsing-remitting
multiple sclerosis; but was not associated with a significantly lower risk of
disability progression at 12 weeks.

Conclusion

 


Elevations in liver aminotransferase levels, more than
5 times the upper limit of the normal range, was present in 6% of patients
treated with daclizumab and in 3% in the group treated with interferon
?-1a.


Cutaneous events such as eczema or rash were more
common in patients treated with daclizumab (37%) than with interferon
?-1a (19%).


Infections were more common in the daclizumab HYP group
(65%) than in the interferon beta-1a group (57%) .


Five patients
died during the study; four in the interferon ?-1a group and one in the daclizumab HYP group.

Serious adverse events were reported in 15% of the
patients treated with daclizumab HYP while 10% was reported in the interferon ?-1a group. Some of them are listed:

 

Ø 
The number of new or newly enlarged hyperintense
lesions on T2-weighted MRI was lower with daclizumab HYP (4.3) than with
interferon ?-1a (9.4) with a 54% lower number of lesions with
daclizumab HYP; P<0.001. Secondary endpoints Ø  The ARR was lower after treatment with daclizumab HYP (0.22) than with interferon ?-1a (0.39) with a 45% lower rate using daclizumab HYP; P<0.001 Primary endpoint The following data represent the results that were statistically significant (P<0.05) comparing the results of daclizumab HYP with interferon ?-1a: Results   This was a multicenter study with 230 study locations in America, Europe, Asia (excluding Japan) and Australia.
