Advocacy group and former antitrust official look to comment on Illumina's controversial Grail merger
As Illumina continues to fight for its $7.1 billion Grail buyout, the American Antitrust Institute and a former antitrust official want to get involved.

The Washington DC-based advocacy group and William Baer, former director of the FTC’s Bureau of Competition and assistant attorney general for DOJ’s antitrust division, filed a request on Monday to submit an amicus or “friend of the court” brief on a proposed fix that would have “important implications for the future of merger law and sound antitrust enforcement.”
It’s the latest move in a long-running battle against Illumina’s attempt to re-acquire its blood testing spinout Grail, which was originally launched out of Illumina in 2016. The FTC filed a complaint about the merger last March, arguing that it would stifle innovation for liquid biopsy cancer screening tests called multi-cancer early detection or MCED tests, being developed by Grail and several rivals.
While judge Michael Chappell dismissed the complaint in early September, EU regulators blocked the acquisition just days later. The bloc noted that rival companies rely on Illumina’s sequencing technology for their own products.

“With this transaction, Illumina would have an incentive to cut off GRAIL’s rivals from accessing its technology, or otherwise disadvantage them,” European Commission EVP Margrethe Vestager said in a statement at the time. “It is vital to preserve competition between early cancer detection test developers at this critical stage of development.”
Illumina said it would appeal the decision with general counsel Charles Dadswell arguing that the merger is “pro-competitive and will accelerate innovation.”
“Illumina can make GRAIL’s life-saving multi-cancer early detection test more available, more affordable, and more accessible – saving lives and lowering healthcare costs,” Dadswell said in a news release.

In dismissing the case back in September, Chappell acknowledged that Illumina is the “only viable supplier” of next-gen sequencing platforms needed by other MCED test developers. However, he also added that a long-term supply agreement by Illumina, or Open Offer, prevents it from harming Grail’s rivals, calling the FTC’s arguments otherwise “unconvincing.”
Baer and AAI said their brief would “address the role of the merging parties’ Open Offer in the Initial Decision and aspects of Judge Chappell’s approach to ‘litigating the fix.’”
Neither were immediately available for comment on Thursday.
