Key third-quarter readouts for big pharma
Abbvie expects more Rinvoq data in ulcerative colitis while Astrazeneca takes on myasthenia gravis, and gene therapy is in play for Pfizer and Roche.
After a busy second quarter that saw a monumental approval for Biogen’s Aduhelm before the company's Sage-partnered depression project zuranolone stumbled, the third quarter is nearly here.
Over the next three months Astrazeneca/Alexion’s Ultomiris will get a turn in myasthenia gravis, while data are also expected on Pfizer/Roche's gene therapy in haemophilia B. Novartis, meanwhile, is betting on Tim-3, and Abbvie is due more ulcerative colitis results.
Abbvie's Jak inhibitor Rinvoq looks set to dominate in ulcerative colitis, with nearly half of its total 2026 sales assigned to this indication, according to Evaluate Pharma consensus.
Maintenance data from the U-achieve study are due in the summer and will form part of second-half regulatory filings. Rinvoq already has two positive induction studies in the bag, with data looking superior to other Jak inhibitors, including Pfizer's Xeljanz and Galapagos's Jyseleca, as well as biologicals such as anti-TNFs and IL-12/23s.
Rinvoq’s safety profile will have to remain clean over longer-term treatment. Regulators in the US appear particularly cautious about the Jak class. A number of approval decisions for Jak inhibitors have been pushed back by the FDA after Pfizer's Xeljanz failed to show non-inferiority to a TNF inhibitor on rates of major adverse cardiovascular events and cancers.
Competition hots up
Astrazeneca/Alexion’s Ultomiris is due to yield phase 3 data in the second half in myasthenia gravis, but is forecast to become only the second-biggest drug in this indication by 2026, according to Evaluate Pharma consensus, behind Argenx’s efgartigimod, which is set for an approval decision this year.
The 175-patient study tests Ultomiris given IV every two months versus placebo, and measures change from baseline in MG-ADL total score at week 26 as primary endpoint.
On a cross-trial basis efgartigimod’s Adapt study provides a yardstick. 70% of subjects met the primary endpoint, an improvement by at least two points on the MG-ADL symptom scale over eight weeks, versus almost 30% in the placebo cohort, but the weekly IV project missed statistical significance over the full 26 weeks.
A more convenient option is still needed for patients, and Argenx is ahead here with SC efgartigimod in phase 3.
Pfizer and Roche expect phase 3 data soon with their haemophilia B gene therapy fidanacogene elaparvovec, although timings are vague – Pfizer has said a planned interim analysis is expected for a potential readout this year.
Benegene-2, in 55 patients with moderately severe to severe haemophilia B, with a Factor IX (FIX) circulating activity of 2% or less, has primary endpoints of annualised bleeding rate and levels of circulating FIX at 12 months.
An earlier study showed that the mean post-infusion steady-state FIX for 15 treated patients was 23% at one year, with 12 of 15 patients reporting zero bleeds in the 52 weeks.
Fidanacogene elaparvovec will have to live up to Uniqure's rival project, etranacogene dezaparvovec, which recently reported durable results at one year in its pivotal trial, Hope-B. However, etranadez has been delayed by around six months after the FDA asked for 18-month data on annualised bleeding rates (Haemophilia B delay hits Uniqure, June 23, 2021).
With the renewed appetite for novel checkpoint inhibitors, investors will be watching for data with sabatolimab, a Tim-3 antagonist. Novartis gained the project, then known as MBG453, via the takeout of the private group Costim in 2014.
Novartis’s phase 2 Stimulus MDS-1 study due to report in the second half tests 120 adult subjects with myelodysplastic syndrome, and combines sabatolimab with hypomethylating agents. Complete remission data are expected, and PFS is a co-primary endpoint.
With phase 3 already under way sabatolimab is the most advanced Tim-3 project, followed by Glaxosmithkline’s cobolimab. Proof of concept data with cobolimab are expected before the end of the year from the phase 2 Amber study.
