A recent Pear Therapeutics–Avalere survey of 30 payers and 10 employer self-insured groups identified numerous insights to direct future efforts for broader adoption and coverage of prescription digital therapeutics (PDTs).

Prescription Digital Therapeutics (PDTs) are a growing and unique treatment modality that can provide expanded options for treatment to patients. As the landscape for these treatments develop across multiple therapeutic areas, challenges related to coverage, reimbursement, and access will need to be solved to advance broader adoption and utilization across key stakeholders.

Beginning July 1, 2021, average sales price (ASP) calculations for Part B drugs with an additional non-covered self-administered formulation could alter Medicare reimbursement.

The 351(k) biosimilars pathway was legally established under the Biologics Price Competition and Innovation Act (BPCIA) provision of the Patient Protection and Affordable Care Act (ACA) of 2010. Since the passage of the ACA, 28 biosimilars have been approved by the Food & Drug Administration (FDA) along with the promulgation of policy that also applies to all biologics, including the creation of a suffix within the nonproprietary name of these products. Additionally, substantial case law has been made with respect to intellectual property pertaining to biologics. With the legality of the ACA currently under scrutiny, the future of BPCIA and biosimilars is uncertain.

The replacement to North American Free Trade Agreement (NAFTA), the United States-Mexico-Canada Agreement, was originally proposed to increase biologics exclusivity in Mexico and Canada to 10 years. As part of the Administration’s compromise with the House of Representatives, these provisions have been removed from the amended version that was recently agreed to by the US, Mexico, and Canada. While exclusivity in the US remains unchanged at 12 years, that it is not increased for Canada and Mexico may impact market entry for biologics ex-US.

The USMCA’s intellectual property provisions add additional layers of ambiguity to the already complex issues surrounding biological product exclusivity and its future in US law.

While precision medicine is expected to revolutionize patient therapy, the increasing complexity of diagnostics is leading policymakers to revamp the way these tests are regulated and paid for.
