Introduction This document contains instructions on how to complete the electronic Case Report Forms (eCRF) in Medidata Rave for this study. It is important for data analysis purposes that subject data is collected in a uniform manner by the numerous institutions participating in this study. Therefore, the eCRF Completion Guideline is an important reference to use when completing the eCRF. All persons involved in the data collection/data cleaning of this study must familiarize themselves with this guideline. Adherence to this guideline will minimize the number of requests for data clarifications. These guidelines are available from a link in Rave from the home page as well as from the individual forms.

System Access

New users will receive an account activation e-mail from Medidata [email protected]. (including a link to create a user profile (username and password). (From October 2021 on, the e-mail address changed from [email protected] to [email protected]). Users who already have a Medidata account will see invitations in the Tasks pane on their iMedidata home page. NOTE: The account activation e-mail is only valid for 30 days. If the user does not use the link within 30 days, a new account activation e-mail will need to be sent. In this case, the site should contact the CRA. All users will be required to complete an on-line training. Upon completion of the training course, users will automatically have access to the eCRF of the study. Once a user has taken and passed a required course, they do not have to retake it to access other teams or studies that require it. However, if a change is made either to the application or to update the course, users may have to retake a course. Each site will have access to its own data only. Username and password should not be shared with others. For security reasons, please do not leave password information in a place where others may have access to it. Passwords are valid for 120 days and require to be at least eight (8) characters in length, contain at least one uppercase letter, one lowercase letter, and one number, to be at least of moderate strength, and not to be one of the last ten (10) passwords. Upon password expiration, users will automatically be prompted to change their password at login. For password re-sets, please see following section “Trouble Shooting and Support”. NOTE: Data may be entered into Rave by two roles: Clinical Research Coordinator (sometimes also referred to as Site Coordinator or Study Nurse) and Investigator. Users with one of these roles may also respond to queries.

Trouble Shooting and Support For technical assistance, site staff should contact the Medidata Helpdesk via email to [email protected]. (From October 2021 on, this e-mail address changed from [email protected] to [email protected]).

What’s the Potential Impact If your associated systems that accept Medidata emails are not enabled to whitelist the @3ds.com email domain, those emails could be rejected or go into a SPAM container. Communications could be disrupted. For non-technical issues regarding completion of the eCRFs sites should contact their Monitor primarily. The CRA may reach out to Clinipace Data Management if further support is needed Lead CDM: [email protected], CDM backup: [email protected], CDM backup 2: [email protected]) or to LEO Pharma Data Management.

On the top right-hand corner of each RAVE screen, there is a HELP icon that could be clicked for general RAVE instructions. The maximum number of incorrect logins before accounts get locked is 5. When this happens, the account needs to be restored by clicking on the “Forgot Password?” link on the login page. You will have to enter the e-mail address linked to the account. An e-mail will be sent to this address with a link to create a new password. NOTE: Rave is not validated to work in iOS (Apple) or Android phone platform internet browsers.

General Instructions Completion and signature of the eCRFs for all subjects at the site may be the responsibility of one or more study staff member(s) listed on the Site Delegation and Signature Log. The Investigator is the only staff member that can apply an electronic signature. The eCRFs need to be signed electronically by the Investigator to confirm that all data are completely and accurately entered. The eCRF is set up ‘dynamically’, which means that depending on an entry made by the site, sections will get enterable and/or pages/visits will be added for the subject to reflect the appropriate needs. This feature is reversible, and pages/visits will disappear, or sections will get non-enterable (greyed out) once the triggering entry is changed. NOTE: It is extremely important to FIRST enter the respective visit date Information at each visit, as well as all Adverse Events and Prior and concomitant medication, to display for all eCRF dynamics/defaults correctly (i.e., all adverse events or prior and concomitant medication need to be entered to ensure they are available for dynamic linking on other eCRF pages).

Prancer RTSM data transfer (4G Interactive Randomization Tool (IRT) system) The Prancer Randomization and Trial Management (RTSM) system is where the subject is first created. NOTE: The access to RAVE does not grant access to Prancer RTSM, a separate training would be needed for the access. Data on the fields below are automatically loaded into RAVE from Prancer RTSM. These fields cannot be modified in the RAVE EDC system. They are read only and protected and can be identified by the suffix “(Transferred from IRT)”. Any changes need to be made inside the Prancer RTSM system.

Subject Identification Once a subject has been added in the Prancer RTSM system, the subject number and site ID is then transferred into Medidata RAVE. The format for Subject numbers is ssss-yyyy-zz, where:

ssss = trial number = e.g. 1488

yyyy = LEO unique site location ID (without country identifier)

zz = serial participant number starting from 01 for the first participant at a site

Example: 1488-1001-01. The following folders will then appear for data entry: Visit 1 (Screening) Visit 2 (Screening/run-in) AE/CM/CP events Trial completion/discontinuation Screen Failure Comments Log The following information will be transferred from 4G IRT system:

• Subject and site identification number

• Screening: date of birth, sex, age at screening

• Re-screen: previous subject identification number

• Randomisation: date of randomisation

• Screen failure: Date of screen failure

• IMP dispense and return: Kit number(s)

Entries NOTE: Data should be entered into the eCRF in a timely manner and within 5 business days of the subject visit.

All entries must be complete and entered in English. Avoid using abbreviations and symbols wherever possible. Do not use special characters (e.g. letters with accents, cedilla, semicolon, dollar sign), since special characters cause problems during data evaluation. In general, ensure that there are no missing data (blank fields) in the eCRF. If additional specification is requested for an item in the eCRF, please ensure that a specific entry is made (e.g. “Was the ECG performed?”, if “Yes” is ticked, enter all information). There may be some CRF pages where not all information is available at once, e.g. on the Central Laboratory form the site may tick that blood sampling was performed, but the result is not yet available. If the result is not entered within the next 4 days a query will fire. Other queries may fire with a delay of 1 day awaiting user’s data entry on a 2nd CRF page.

Ensure that all data in the eCRF reflect the source data. If data entered is non-conformant (e.g. letters entered into a numeric field or an impossible date),

then the field is flagged as non-conformant and must be corrected. If the data is not corrected, Data Management will issue a query for this field. NOTE: Visit folders appear dynamically in subjects’ eCRF. See section ‘Subject Identification’ for folders that appear right from the beginning. Other visit folders are triggered by data entry, e.g., usually the next visit becomes visible once the visit date of the current visit is entered/saved.

Screen Failures Screening failures are all subjects who provided informed consent but are not randomized to treatment. In addition, subjects who withdraw/are withdrawn from the trial prior to randomization will be considered screening failures. An appropriate reason should be provided on the Screen failure form (see Visit Screen failure). The following pages must be completed:

• Visit 1 (Screening) with:

• Visit date

• Informed Consents

• Demographics

• Subject Eligibility

• ECG (only, if performed and transferred to the ECG vendor)

• Central Safety Lab (only, if a sample has been taken and send to the central laboratory)

• Visit 2 (Screening-run-in), if applicable

• Visit 3/Week 0, if applicable NOTE: There is no need to fill in details of further assessments, irrespective of whether performed or not). For consistency reasons and reconciliation of data, ECG form or Lab assessment form should be completed if an ECG or a lab sample was processed by the ECG/Lab vendor before the subject was determined to be a screen failure.

• Visit AE/CM/CP events o Answer the question 'Did the subject have any adverse events since screening'. If the

question is answered ‘Yes’, respective details must be entered on an Adverse Event form. No information about Concomitant Medication or Concurrent Procedures needs to be provided.

• Visit Screen failure o Screen failure form including reason for screen failure

Detailed instructions on the completion of each form can be found in the section ‘Instructions for study-specific eCRF modules.

Early Termination (ET) of subjects For a subject discontinuing from study after randomization but before week 16 the following eCRF pages must be completed:

NOTE: A subject stopping IMP prematurely is encouraged to stay in the trial without getting more IMP. The "end of trial" form is only to be filled in when the entire trial is stopped, which may be after the IMP is stopped.

• For all subjects (either No IMP or IMP was administered):

• Visit Trial completion/discontinuation including End of Trial form

• AE/CM/CP events o If one of the questions is answered ‘Yes’, respective forms must be completed.

• If IMP was administered, in addition:

• End of treatment/Visit 16

• Safety follow-up visit (7 days after the last IMP application), if performed

• Early IMP termination including EASI, VIGA_AD, SCORAD, Physical examination 2, Vital Signs, Fasting, ECG 2, Urine pregnancy test, Central Laboratory 2, Pharmacokinetics, Blood biomarkers, Skin Biopsy – lesional, Actigraphy 2, Early termination, if performed

• Treatment completion/discontinuation including End of treatment form

Detailed instructions on the completion of the forms can be found in the section ‘Instructions for study-specific eCRF modules’.

Unscheduled Visit On the subject casebook homepage please click on the ‘Add event’ drop-down box and select the Unscheduled Visit to be added for entry and save.

This will trigger the Unscheduled visit – type of assessment page.

The reason for the Unscheduled visit should be selected. If Adverse event/safety is selected, please record the Adverse event as appropriate. The "Unscheduled Visit" is a folder where all additional examinations should be recorded, regardless of when they were done. This visit in the eCRF is not a complete/normal visit, i.e. not all eCRF pages need to be entered (e.g. if only additional vital signs were measured, please only enter an additional vital signs eCRF page). NOTE: Detailed instructions on the completion of the Unscheduled Visit forms can be found in the section ‘Instructions for study-specific eCRF modules’.

Source Data All data entered in the eCRF should correspond accurately with the source documents. Otherwise, unnecessary queries will be generated.

CRF structure Upon creation of a subject ID, the default matrix (set of folders and forms) is displayed. By clicking on a folder (e.g. Screening) all forms for this visit will be displayed. NOTE: Always start completing the eCRF by adding the Visit Date of the associated page/form.

Not all folders (visits) and forms will be available immediately upon creation of a new subject ID, they will become available upon entering the prerequisite data. When multiple instances of the same form/page are needed (e.g. concomitant medication or adverse event), a log form is used to add additional records to one form. Log forms can be in portrait or landscape mode.

Inactivating and reactivating pages A page can be inactivated to indicate that no data is applicable to be entered on it (e.g. if data has been entered in error in a dynamically created form and the whole page needs to be disregarded). In case examinations/assessments of a conducted visit were not performed, the respective pages should be handled as follows:

• if the eCRF page has a leading “Yes” or “No” question for the examination/assessment, answer “No” to the question and specify a reason, if applicable

• if there is no leading “Yes” or “No” question, inactivate the eCRF page

Pages inactivated in error can be reactivated again. The permission to inactivate/reactivate pages is restricted to the CRA and Data Manager role.

Log lines Where several log lines are used in forms (e.g. Adverse Event or Prior and concomitant medication), the first row is ready for entry. You do not need to add the first log line from the “Portrait View”. If data is missing on the first row a query may appear to request completion. The “Add a new Log line” link should then be used for generating additional rows, as needed. To edit data within a log line, click any item in the log line or click the pencil at the right-hand side of the log line. Each additional log line must be saved separately. If a new log line is entered before the previous log line is saved, the previous entry gets lost.

Inactivating and reactivating log lines If a log line has been created in error (e.g. duplicated entry, blank line created in error) the log line can be inactivated by site personnel. NOTE: Please do not just leave the fields blank if an entire log line needs to be removed from the eCRF. This will create a blank record in the eCRF and queries may be raised asking for the missing data. Log lines inactivated in error can be reactivated again. The data entered previously can be activated again.

Numeric fields Numeric fields are left-aligned, and values can be entered with or without a leading ‘0’. If a value is less than 1 (e.g. 0.225) please always enter the leading 0 and use “.” as the decimal delimiter.

Date fields The visit date should be completed according to the protocol schedule. Due to the in-built dynamics in this study, it is recommended that the visit date should always be entered at first before continuing with other data. Dates are entered in three fields in Rave: day of month (e.g. 01), month (from a drop-down list e.g. "Jan"), then year in four digits (e.g. 2014). Partial date: Partial dates are accepted for some fields if the exact date cannot be obtained. Fields for which a partial date is accepted are described in the form-specific section of this document. If a partial date is allowed and the exact date is unknown, please enter “UN” (uppercase) for the missing day of the month and select “UNK” for a missing month from the drop-down list. Where dates are expected to be complete, all efforts must be made to obtain missing day/month. If UN is entered into the day for these dates, a non-conformant query will appear. Either the date has to be corrected or a confirmation (e.g. day not known) should be entered in the query response field. Every effort should be made to provide at least the year. The year must always be entered as a valid number. No “UNK” will be accepted. If the year is not known, please leave the whole date blank - in this case don’t enter “UN” for day or “UNK” for month. A query will fire. Please confirm in the query response field that the date is genuinely unknown. If any further relevant information is available, please enter it as a comment on the comment page.

Check Boxes If a question has multiple answer options collected by a check box, more than one answer can be selected. If an answer needs to be de-selected and no answering option should be selected, click into the marked field to remove the answer.

Entering comments If a site would like to provide additional information or is requested to do so, e.g., by the Medical Expert, this can be done on the ‘Comments’ form.

Missing data Missing codes (like UN or UNK for unknown) are only set up for specific data fields. All other data fields are required. If there is no data, leave the field blank. A query will be generated requesting the missing data. Confirm in the query response field that data is missing and provide a reason, if possible.

Drop down list boxes

For some fields you must select the answer form a drop-down list with pre-populated text for selection. Data entry can be accelerated if the first letters of the answer are typed in rather than scrolling through the drop-down list.

Derived fields Derived fields (e.g. Date of randomisation) will be filled automatically when the page is saved (transferred from 4 G Clinical IRT system). These items are visible but not changeable.

Derived fields can be identified by the icon.

Workflow and Queries Immediately after data has been entered into the form and the “Save” button at the bottom of the page is clicked, a system query will appear right next to the field if there are any discrepancies. The query is highlighted in red/pink, with the icon showing as a question mark. These will also be shown as open queries in the “Task Summary” and “Grid View”. Depending on the type of error (missing data, inconsistent data, etc.) the query text will be a short instruction, or a more detailed explanation of the issue.

If the issue is more complex or the inconsistent data is entered on several pages, more detailed query text will be displayed, with reference to which other page this check is referring to. In this case, please check all pages concerned and correct the data where necessary. In addition, manual queries can be generated by the CRA or Data Manager (Clinipace or LEO). To respond to a query: - either enter/correct the data (and provide an audit reason, e.g. “Data Entry Error” or “Updated

Information”)

- Or, if the data is correct (but not as expected), please leave the data as it is, and confirm the data in the query response field (e.g.: “I confirm this value” or “date is correct”, etc.)

Please remember to click Save once done. The person who raised the query will then either close the answered query or send a re-query, as appropriate. NOTE:

o System queries will only close automatically if the discrepancy is solved. In case the discrepancy is not solved, but a valid comment is present, the Data Manager will close the query manually.

o Manual queries will never close automatically. They will be closed by the Data Manager or CRA, depending on who raised the query.

o If a query is generated on a page which has already been verified by the CRA and signed by the Investigator this page needs to be verified by the CRA and signed by the Investigator again if results in a data change.

o Responses to queries should be made within 5 business days.

Verification Since this study applies targeted Source Data Verification (tSDV) the amount of Source Data Verification (SDV) performed on each subject varies. CRAs will either freeze single items or the whole forms once they have finalized verification.

Data freeze After the site personnel have entered the data into the eCRF and the CRA has verified the data to ensure compliance and completeness, the CRA will flag the eCRF page as “Frozen”. If only single items on the page were verified only this item should be frozen. Once a page or an item has been frozen, site personnel will not be able to change data. Frozen pages ensure stable/unchangeable data to start cleaning activities by the data manager. If manual queries must be raised the Data Manager or CRA will first unfreeze the page and thus allow the site to make the changes. Afterwards, the CRA will re-verify and freeze the “unfrozen” page again.

Data lock Pages will be flagged by the Data Manager as “Locked” to indicate for all user that all data is clean. In case an item or form would need to be unlocked for any data update, the CRA will inform the data manager who will unlock the item or form, as needed. The CRA will re-verify and freeze the “unfrozen” page again and afterwards, the page will be locked again by the data manager.

Investigator Signature – Approval Process After data for the subject is entered, reviewed, and all discrepancies are resolved, the investigator signs all eCRF pages electronically. He/she confirms that data is complete, accurate and reflects the source documentation. The Sub-Investigator is also authorized to sign eCRF pages electronically if documented in the delegation log. The electronic signature will be created in compliance with the FDA regulation 21 CFR Part 11.

Medical and surgical history

Please document in this module any relevant diseases the subject had in the past as well as any relevant diseases present at the time the subject signed informed consent. Also record any relevant chronic conditions that are intermittent or recurrent in nature. NOTE: Any medications related to the condition or diagnosis should be recorded in the Prior and concomitant medication form

NOTE: Do not report the indication of the study disease (atopic dermatitis). After signing the Informed Consent any worsening of a pre-existing disease/illness or newly emergent disease/illness between Informed Consent and randomization must be reported as medical history. Any worsening of a pre-existing disease/illness or newly emergent disease/illness after randomization must be reported as an adverse event. The medical history page must be consistent with clinically relevant abnormal findings in the physical examination, vital signs, laboratory results, other clinical evaluations, and entries on the prior/concomitant medication form. To record more than one medical conditions/diagnoses/procedures, click on the ‘Add a new Log line’ link. Does the subject have any concurrent diagnoses or relevant medical or surgical history within the previous 12 months? If the subject has either experienced any relevant medical history since birth and/or any other medical or surgical history including concurrent diagnoses within the previous 12 months, select “Yes” and complete the following section with details of appropriate conditions or diagnoses and consider the impact on the inclusion/exclusion criteria. Otherwise, select “No” and leave the page blank. NOTE: If yes, please complete the following section with details of appropriate conditions or diagnoses and consider the impact on the inclusion/exclusion criteria.

NOTE: If response for ‘Does the subject have any concurrent diagnoses or…?’ is No, then all the fields in the Log Lines will become inactive so data cannot be entered. Condition or diagnosis

• Record all relevant past and/or concomitant medical conditions and past surgeries, as defined in the protocol.

• Record only one condition or surgery per line.

• When recording a condition and surgery related to that condition, use one line for the condition and one line for the surgery.

• Ensure that any of the conditions listed on the Medical History page does not violate the in-/exclusion criteria.

• If multiple signs/symptoms can be captured by a single diagnosis, enter only that single diagnosis.

• Recording of diagnoses is preferred to describing which values were out of range (e.g., record “hypercholesterolemia” instead of “high blood cholesterol level”).

• Do not use abbreviations

• Probably related: Follows a reasonable temporal sequence from administration of the IMP. Could not be reasonably explained by the subject’s clinical state, environmental or toxic factors or other therapies administered to the subject. Follows a known pattern of response to the IMP. Disappears or decreases on cessation or reduction in dose of the IMP. Reappears or worsens upon re-challenge.

• Possibly related: Follows a reasonable temporal sequence from the administration of the IMP. Could also be reasonably explained by the subject’s clinical state, environmental or toxic factors or other therapies administered to the subject. Follows a known pattern of response to the IMP.

• Not related: Does not follow a reasonable temporal sequence from administration of the IMP. Is better explained by other factors like the subject’s clinical state, environmental or toxic factors or other therapies administered to the subject. Does not reappear or worsen upon re-challenge. Does not follow a known pattern of response to the IMP.

Action Taken with IMP Any action taken with the IMP as a consequence of the AE must be recorded. Tick the appropriate box: Select ’Drug interrupted’ if the IMP is temporarily discontinued Select 'Drug withdrawn' if the IMP is permanently discontinued.

Outcome The outcome of the event according to the investigator’s clinical judgement should be classified using the categories below. Record the appropriate outcome of the event in relation to the subject’s status at the end of the study. If the subject died, only the AE representing the underlying cause of death should have the outcome ‘fatal’; all other AEs that were present at the time of death should be reported as ‘not resolved’. Record the stop date if the AE has the outcome ‘Recovered/resolved’, ‘Recovered/resolved with sequelae’ or ‘Fatal’.

• Fatal: The subject has died as a consequence of the event. Date of death is recorded as stop date for the AE.

• Not recovered/not resolved: Event is still ongoing.

• Recovering/resolving: The subject is clearly recovering from an event. The event is not yet completely resolved.

• Recovered/resolved: The event has stopped. The stop date of the event must be recorded.
