“Biosimilar” or “Biosimilarity‘’, in reference to a biological product that is the subject of an application under subsection (k) of 42 U.S.C. 262, means:

(A) that the biological product is highly similar to the reference product notwithstanding minor differences in clinically inactive components; and

“Interchangeable” or “Interchangeability', in reference to a biological product that is shown to meet the standards described in subsection (k)(4) of 42 U.S.C. 262, means that the biological product may be substituted for the reference product without the intervention of the health care provider who prescribed the reference product.

“Reference product” means the single biological product licensed under subsection (a) against which a biological product is evaluated in an application submitted under subsection (k) of 42 U.S.C. 262.

“Prescription”, with respect to a biological product, means an order for a product

that is subject to Section 503(b) of the Federal Food, Drug and Cosmetic Act (21

Subsection (b).  A biosimilar product determined to be interchangeable by the United States Food and Drug Administration (FDA) shall be available for substitution in the Commonwealth, in accordance with the provisions of this Act, Chapter 94 of the General Laws and any other applicable laws.

Subsection (c).  Except as provided in subsection (d), a pharmacist filling a prescription for a biological product prescribed by its trade or brand name may substitute any biosimilar product that the FDA has determined to be interchangeable with the prescribed product.

Subsection (d).  The pharmacist shall not substitute a biosimilar product that is interchangeable with the prescribed product if the prescriber instructs otherwise, either orally or in writing, pursuant to this Chapter. Such instruction shall be on a patient-specific basis.

Subsection (e).  No additional restrictions, limitations or requirements shall be imposed related to biological product substitution unless such restrictions, limitations or requirements also apply in the case of all other drug product substitution.
