As Summit Therapeutics’ Chinese partner prepares to reveal data for a key trial at ASCO, analysts consider the impact on rivals Merck, Bristol Myers Squibb and BioNTech.
The antisense oligonucleotide was even more effective in patients with relatively low viral activity. More than one-quarter of these individuals had undetectable levels of the virus in the blood for at least six months after stopping treatment.
Treatment with the TROP2 ADC sac-TMT led to a 70% objective response rate and progression-free survival was “significantly improved” as compared to placebo—the second positive readout for the asset this week.
After being hit by safety issues and subpar results in another trial, BioMarin’s Phase 3 test of Voxzogo for a rare skeletal disorder called hypochondroplasia showed efficacy “solidly above” what the drug has shown for achondroplasia, which causes dwarfism.
UCB’s Bimzelx elicited significantly stronger joint relief at 16 weeks than AbbVie’s Skyrizi in a Phase 3 head-to-head study of psoriatic arthritis.
BioMarin’s investigational therapy failed to elicit clinical improvements in patients with ENPP1 deficiency, while also missing key secondary endpoints of rickets severity and growth.
Merck and Kelun-Biotech’s antibody-drug conjugate significantly improved progression-free and overall survival in a pivotal endometrial cancer study, though the companies have yet to specify when they plan to file for approval.
The late-stage miss shakes analyst confidence in Regeneron’s clinical execution, according to BMO Capital Markets, also noting last year’s Phase 3 failure in chronic obstructive pulmonary disease.
Indirect comparisons between BridgeBio’s Attruby and Pfizer’s tafamidis products showed a numerical survival benefit with the biotech’s drug.
Pfizer-backed cancer company CellCentric will use the cash to support the launch of a pivotal myeloma trial testing its potentially first-in-class oral treatment this year.
