LAX Leader

A provision of the “Inflation Reduction Act” (IRA) could threaten investments in "small molecule" drug development, said the head of the Pasadena-based Pacific Research Institute (PRI).

There are currently up to 8 Los Angeles biopharma companies involved in that type of drug development, according to Biopharmguy.com. 

PRI President Sally Pipes told South SFV Today on Feb 26 that a so-called "small molecule penalty" in the Inflation IRA will “have an outsized impact on our efforts to development treatments for cancer.”

Pipes said that the announcement by Stanford Researchers in December that they had discovered an “on/off switch” for breast cancer is but one example of a “small molecule” drug innovation.

The IRA, signed into law by President Joe Biden (D) in 2022, contains a drug provision in which the brand-name drugs for which Medicare "negotiates" prices are split into two categories: small-molecule drugs and biologics. 

The IRA makes small-molecule drugs eligible for "negotiation" nine years after their approval, compared to a 13-year exemption period for biologics.

“While both small-molecule drugs and biologics are essential for cancer treatment, small-molecule drugs are the only way to target some forms of breast, lung, colon, and other cancers,” she said. 

An October 2023 paper, authored by University of Chicago economists, said that the IRA small molecule provision will result in “188 fewer small molecule treatments, including 79 fewer new small molecule drugs and 109 fewer post-approval indications for these drugs.”
