The U.S. FDA rolled out its anticipated “plausible mechanism” draft guidance, enabling ultrarare disease drug developers to generate evidence of effectiveness and safety to support approval when randomized controlled trials are not possible due to small patient populations.
Following a clinical hold last October of Intellia Therapeutics Inc.’s Magnitude and Magnitude-2 phase III trials of CRISPR/Cas9 gene editing therapy nexiguran ziclumeran (nex-z) to treat transthyretin amyloidosis with cardiomyopathy (ATTR-CM) and polyneuropathy (ATTR-PN), respectively, the U.S. FDA lifted the hold on Magnitude-2, pushing the company’s shares up by 22% in early trading Jan. 27.
After selling off amyotrophic lateral sclerosis therapeutics last month, Tanabe Pharma America Inc. emerged a forerunner in another rare disease space with positive top-line phase III data of dersimelagon (MT-7117) for erythropoietic protoporphyria/X-linked protoporphyria.
The good news is that the U.S. Congress is on track to pass a slate of fiscal 2026 spending bills before the current continuing resolution expires Jan. 30.

The U.S. FDA has approved Zycubo (copper histidinate) as the first treatment for Menkes disease, a rare, genetic disease affecting children who cannot absorb copper through their intestines, leading to seizures, weak muscles, a failure to thrive and, ultimately, if left untreated, an early death by age 3.
A second complete response letter issued by the U.S. FDA for Atara Biotherapeutics Inc.’s allogeneic T-cell immunotherapy Ebvallo (tabelecleucel) for Epstein-Barr virus positive post-transplant lymphoproliferative disease is “a complete reversal of position” by the agency, which had previously confirmed the single arm Allele trial was enough to support a BLA under the accelerated approval pathway, the company said.
