FDA appears to be like to simplify biosimilar growth with new draft steering
The US Meals and Drug Administration (FDA) has debuted new draft steering that goals to streamline and expedite the biosimilar growth course of.
The regulatory framework has been designed to cut back the reliance on “pointless medical testing” in the course of the approval course of. Which means biosimilar producers will not should conduct comparative efficacy research on their potential medicine.

As a substitute, the FDA will use its accrued expertise in assessing purposes via comparative analytical and medical research to assist decide if a biosimilar’s efficacy and security is akin to its branded counterpart.
Alongside its change in stance on comparative efficacy trials, the company additionally not recommends switching research, as they will “sluggish growth” whereas creating “confusion amongst the general public” concerning biosimilar security. Switching research have historically been carried out to show a biosimilar is as protected and efficient because the branded various.
By way of this draft scheme, FDA Commissioner Marty Makary famous that the US might see “large price reductions for superior remedies”, particularly in uncommon ailments, oncology and autoimmune ailments. He additionally famous that, underneath the framework, producers might save roughly $100m in growth prices, whereas slicing biosimilar growth timelines in half.
Below a separate initiative, the company can even simplify the method of growing interchangeable biosimilars, that means that sufferers and prescribers can simply establish low-cost model alternate options.
This biosimilar push intently follows the debut of the FDA’s ANDA generic pilot prioritisation scheme, which was launched in early October 2025. Pharmaceutical Expertise beforehand spoke with Giuseppe Randazzo, senior vice-president of sciences and regulatory affairs on the Affiliation for Accessible Medicines (AAM), in regards to the implications of this framework.
Tackling drug pricing issues
The introduction of this draft steering comes amid drug pricing issues within the US – a phenomenon that particularly applies to advanced biologic medicines.
Whereas branded therapies characterize simply 5% of US prescriptions in 2024, they accounted for a little bit greater than half of the nation’s complete drug spend that 12 months. This highlights the high-cost burden of branded medicine on each the US healthcare system and the affected person inhabitants.
To deal with this, the FDA has gone for a ‘carrot’ strategy whereas the Trump administration is attempting its luck with the ‘stick’ technique – threatening branded pharmaceutical producers with 100% import tariffs if they don’t cut back their US drug costs.
This noticed Pfizer turn into the primary pharma firm to strike a take care of Trump, agreeing to chop US costs of choose medicines in its portfolio in trade for a three-year tariff exemption. AstraZeneca intently adopted go well with, signing a take care of the Trump administration round two weeks later.
Each Novartis and Roche are actually in conversations with Trump round a Most Favored Nation (MFN) pricing deal, that means the compatriots might quickly attain an settlement with the administration.
Nevertheless, GlobalData analysts are sceptical in regards to the true affect of MFN offers on drug costs, as many sufferers get hold of prescriptions via an insurance coverage plan, that means that concessions accessible via direct-to-patient (DTP) platforms comparable to TrumpRx.gov might not supply important financial savings.
Business sentiments combined
Whereas this draft steering may very well be a step ahead for the biosimilar trade, Cyrus Fan, healthcare and life science analysis analyst at GlobalData, famous that its debut was solely a “small constructive”.
He mentioned: “The introduction of this draft steering might doubtlessly end in extra FDA-approved biosimilars within the close to future – significantly in circumstances the place comparative efficacy research aren’t possible.”
Nevertheless, Fan caveated that branded biologics will “nonetheless have management of the market” via patents, which act as a bottleneck to market entry for biosimilars. Which means the steering “is not going to enhance affected person entry to biosimilars”, however will as an alternative expedite the biosimilar approval course of.
Regardless of this, he said that the framework might incentivise biosimilar producers to supply their therapies within the US, as it might “cut back growth timelines and prices”.
In the meantime, AAM’s Biosimilars Council government director and coverage senior vice-president Alex Keeton expressed his enthusiasm for the steering.
In a 30 October assertion, he mentioned: “Branded drug corporations use arbitrary interchangeability designation to delay or block entry to lower-cost biosimilar medicines, that means fewer decisions for sufferers and billions of {dollars} in missed financial savings for the US healthcare system.”
Keeton additionally famous that the US is the one nation on the earth that employs the interchangeability designation, which he believes is “pointless”.
He commented: “Up to date analytical, useful and pharmacokinetic methodologies can detect clinically significant variations.” In his eyes, these strategies are more practical than medical efficacy research.
In line with GlobalData’s Intelligence Centre, there are at present 836 biologics accessible on the US market. Of those therapies, underneath 10% are biosimilars, with 76 biosimilars receiving the FDA inexperienced mild up to now.
