If the pre-defined extension criteria are met at the 4-week visit, and at any follow up visit, the patient will receive a mandated treatment, and the next visit will be extended by two weeks. If the extension criteria are not met on a follow-up visit, the treatment interval will be continued to be reduced by 1 week. If criteria are still not met despite treatment at the reduced interval, treatment will be administered as usual and follow up interval will continue to be reduced by 1 week until the criteria are met or a 4-week interval is reached.
