Yes. The cleaning validation section [ICH Q7, Section 12.7] does not specifically address campaign manufacture. However, sections [ICH Q7, Sections 5.23, 8.50] set forth the expectations that equipment be cleaned at appropriate intervals (e.g., time or number of batches) to prevent build-up and carryover of contaminants so that they do not adversely alter the quality of the API. The appropriate interval is confirmed during cleaning validation.
