Description
Inclusion Criteria:
- Participant has provided informed consent prior to initiation of any study specific activities/procedures.

Exclusion criteria:
- Permanent discontinuation of investigational product during the 52- week phase 2 dose finding parent study (20170104) for any reason
- Female subjects of reproductive potential must agree not to donate eggs during the study and for 6 weeks after receiving the last dose of investigational product.
Disease Related:
Adenoma and dysplasia exclusion criteria:
- Any current sporadic adenoma without dysplasia (adenomatous polyps occurring proximal to known areas of colitis) that has not been removed.
- Dysplasia occurring in flat mucosa, sporadic adenomas containing dysplasia, and dysplasia-associated lesions or masses will be managed as follows:
- Any history or current evidence of high-grade dysplasia.
- Any history or current evidence of dysplasia occurring in flat mucosa.
- This includes histopathology reporting indefinite for dysplasia, low-grade dysplasia, and high-grade dysplasia.
- Any history or current evidence of a nonadenoma like dysplasia associated lesions or masses, with or without evidence of dysplasia.
- Any current sporadic adenoma containing dysplasia or any current adenoma-like dysplasia-associated lesions or masses that has not been removed.
Other Medical Conditions:
- Any malignancy diagnosed during parent Study 20170104, including evidence of cutaneous basal or squamous cell carcinoma or melanoma
- Active infection (including chronic, acute, recurrent, opportunistic infections) at the time of eligibility evaluation requiring intravenous (IV) anti-infectives or hospitalization (infections requiring oral and/or topical anti-infective[s] for > 7 days may be allowed in consultation with the Amgen physician).

- Plan to receive a live (attenuated) vaccine during the treatment period and up to 6 weeks after the last dose of investigational product in the long term extension study.
Prior/Concurrent Clinical Study Experience:
- Currently receiving treatment in another investigational device or drug study. Other investigational procedures while participating in this study are excluded.
Other Exclusions:
- Female participants who are pregnant or breastfeeding or planning to become pregnant or breastfeed during study and for an additional 6 weeks after the last dose of investigational product.
- Female participants of childbearing potential unwilling to use protocol specified method of contraception see Appendix 5 (Section 11.5) during treatment and for an additional 6 weeks after the last dose of investigational product.
- Participant has known sensitivity to any of the products to be administered during dosing with the exception of participants who exhibited sensitivity in parent Study 20170104 but did not result in treatment discontinuation.
- Participant likely to not be available to complete all protocol-required study visits or procedures, and/or to comply with all required study procedures (e.g., Clinical Outcome Assessments) to the best of the participant and investigator's knowledge.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
YES
IPD Plan Description
De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.
IPD Sharing Time Frame
Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities.
There is no end date for eligibility to submit a data sharing request for this study.
IPD Sharing Access Criteria
Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s).
In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling.
Requests are reviewed by a committee of internal advisors.
If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision.
Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement.
This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
Further details are available at the URL below.
