Sec. 58.105 Test and control article characterization.
|
|
(a) The identity, strength, purity, and composition or other characteristics which will appropriately define the test or control article shall be determined for each batch and shall be documented. Methods of synthesis, fabrication, or derivation of the test and control articles shall be documented by the sponsor or the testing facility. In those cases where marketed products are used as control articles, such products will be characterized by their labeling.
(b) The stability of each test or control article shall be determined by the testing facility or by the sponsor either: (1) Before study initiation, or (2) concomitantly according to written standard operating procedures, which provide for periodic analysis of each batch.
(c) Each storage container for a test or control article shall be labeled by name, chemical abstract number or code number, batch number, expiration date, if any, and, where appropriate, storage conditions necessary to maintain the identity, strength, purity, and composition of the test or control article. Storage containers shall be assigned to a particular test article for the duration of the study.
(d) For studies of more than 4 weeks' duration, reserve samples from each batch of test and control articles shall be retained for the period of time provided by § 58.195.

Sec. 58.113 Mixtures of articles with carriers.
|
|
(a) For each test or control article that is mixed with a carrier, tests by appropriate analytical methods shall be conducted:
(1) To determine the uniformity of the mixture and to determine, periodically, the concentration of the test or control article in the mixture.
(2) To determine the stability of the test and control articles in the mixture as required by the conditions of the study either:
(i) Before study initiation, or
(ii) Concomitantly according to written standard operating procedures which provide for periodic analysis of the test and control articles in the mixture.
(b) [Reserved]
(c) Where any of the components of the test or control article carrier mixture has an expiration date, that date shall be clearly shown on the container. If more than one component has an expiration date, the earliest date shall be shown.
