Expanded Access Protocol of Viaskin® Peanut (DBV712) in Peanut-allergic Children

This study is an open-label Expanded Access Protocol to provide continued treatment with
DBV712 for individuals completing a DBV clinical study. Participation is by invitation
according to the inclusion criteria.

For individuals who have received DBV712 for longer than one year prior to entry into
this protocol, where treatment allocation is unblinded, safety assessment and resupply of
DBV712 will occur at 6-month intervals. There will be no other scheduled study visits.
For individuals who have been on blinded treatment, a safety assessment will be conducted
at Months 1 and 3. Visits for safety assessment and resupply of DBV712 will occur at
3-month intervals during the first 12 months. After a year, visits will occur at 6-month
intervals. DBV712 will be supplied to participants at study visits to suffice until the
next visit. For individuals who have been on blinded treatment, or off DBV712 treatment
for more than 14 days prior to entry into this protocol, dosing consists of approximately
6 hours for the first week, 12 hours for the second week, then once daily, at
approximately the same time of day.

Treatment with DBV712 will continue until, in the clinical judgement of the treating
physician, the participant is no longer benefiting from continuation of the treatment,
DBV712 is approved and available by prescription, or the study is terminated.
