Amgen (NASDAQ:AMGN) at this time introduced the presentation of constructive top-line outcomes from the Part 3 MINT trial evaluating the efficacy and security of UPLIZNA ® (inebilizumab-cdon) for the remedy of adults with generalized myasthenia gravis (gMG), a uncommon autoimmune dysfunction. Outcomes from this randomized, double-blind, placebo-controlled, parallel-group trial will probably be introduced on the Myasthenia Gravis Basis of America (MGFA) Scientific Session through the American Affiliation of Neuromuscular & Electrodiagnostic Drugs (AANEM) Annual Assembly, happening Oct. 15-18 in Savannah, Georgia .
The trial met its main endpoint, with a statistically important change from baseline in Myasthenia Gravis Actions of Each day Dwelling (MG-ADL) rating for UPLIZNA (-4.2) in contrast with placebo (-2.2) (distinction: –1.9, p
“Sufferers residing with generalized myasthenia gravis deserve an efficient remedy possibility that gives long-term symptom aid. As soon as authorized, UPLIZNA is anticipated to supply a brand new possibility for sufferers earlier of their remedy plan,” stated Jay Bradner , M.D., government vp, Analysis and Improvement, and chief scientific officer at Amgen. “UPLIZNA targets CD19+ pre-B cells, mature B-cells and a few plasmablasts, that are drivers of the illness. The clinically important outcomes from the MINT trial additional strengthen the rising proof for UPLIZNA in extreme autoimmune ailments and reinforce Amgen’s management in B-cell concentrating on therapeutics.”
Key secondary endpoints had been examined sequentially in a predefined order. UPLIZNA demonstrated a statistically important and clinically significant change from baseline in comparison with placebo for the primary 4 key secondary endpoints.
- UPLIZNA demonstrated a statistically important change in Quantitative Myasthenia Gravis (QMG) rating for the mixed inhabitants (-4.8) in comparison with placebo (-2.3) at Week 26 (distinction: -2.5, p=0.0002).
- Within the AChR+ inhabitants, UPLIZNA demonstrated imply change from baseline (-4.2) in MG-ADL rating at Week 26 in comparison with placebo (-2.4) (distinction: -1.8, p=0.0015).
- Within the AChR+ inhabitants, UPLIZNA demonstrated imply change from baseline (-4.4) in QMG rating at Week 26 in comparison with placebo (-2.0) (distinction -2.5, p=0.0011).
- Within the MuSK+ inhabitants, UPLIZNA demonstrated imply change from baseline (-3.9) in MG-ADL rating at Week 26 in comparison with placebo (-1.7) (distinction -2.2, p=0.0297).
Moreover, within the MuSK+ inhabitants, the imply change from baseline in QMG rating at Week 26 confirmed a pattern favoring UPLIZNA however was not statistically important (-5.2 for UPLIZNA and -3.0 for placebo, distinction -2.3, p=0.1326).
“Myasthenia gravis can have a profound impression on sufferers by inflicting extreme fatigable muscle weak spot that impairs bodily functioning, actions of each day residing and high quality of life,” stated Richard J. Nowak , M.D., M.S., world principal research investigator and director of the Myasthenia Gravis Clinic at Yale College . “This trial demonstrates clinically significant advantages of UPLIZNA, a twice-yearly infused medication with a singular mechanism of motion that selectively targets and depletes CD19+ B cells, that are key upstream drivers of myasthenia gravis. MINT can also be the one Part 3 biologic trial that included a protocol-specified steroid taper, an vital consideration for sufferers as results of extended high-dose steroid use contribute to the general burden of illness.”
The general security outcomes through the placebo-controlled interval of the trial had been in step with the identified security profile of UPLIZNA. The most typical treatment-emergent adversarial occasions had been COVID-19, nasopharyngitis, urinary tract an infection, infusion associated response, headache and cough within the mixed inhabitants.
MINT is the biggest placebo-controlled gMG medical trial for a biologic remedy (238 adults) and enrolled the biggest variety of sufferers (48 adults) who’re MuSK+. The trial additionally included 190 adults who’re AChR+. Additional knowledge will characterize placebo-controlled efficacy and security of UPLIZNA over 12 months in AChR+ sufferers with gMG.
On the 2024 AANEM Annual Assembly, Amgen may even be presenting a poster titled, “The Burden of Glucocorticoid Use Amongst Sufferers with Generalized Myasthenia Gravis in the USA ,” highlighting how increased use of glucocorticoids was related to extra toxicities and total well being care useful resource utilization and prices.
UPLIZNA is presently authorized for the remedy of neuromyelitis optica spectrum dysfunction (NMOSD) in grownup sufferers who’re anti-aquaporin-4 (AQP4) antibody constructive in the USA , European Union, Brazil and Canada , amongst different nations. UPLIZNA was additionally not too long ago granted Breakthrough Remedy Designation for IgG4-Associated Illnesses by FDA following Part 3 outcomes introduced in June.
Primarily based on the MINT main outcomes, Amgen is planning to file for approval within the U.S., adopted by different key markets.
Concerning the MINT Trial
The MINT trial is a randomized, double-blind, placebo-controlled, parallel-group trial ( NCT04524273 ) evaluating the efficacy and security of UPLIZNA in adults with gMG. The trial enrolled 238 adults with gMG, together with 190 sufferers who’re acetylcholine receptor autoantibody-positive (AChR+) and 48 sufferers who’re muscle-specific kinase autoantibody-positive (MuSK+).
Eligibility standards at screening and randomization included a Myasthenia Gravis Basis of America (MGFA) classification of II, III, or IV illness, MG-ADL rating between 6 and 10 with higher than 50% of this rating attributed to non-ocular gadgets, or an MG-ADL rating of at the very least 11, QMG rating of at the very least 11, and use of a corticosteroid and/or non-steroidal immunosuppressant.
The first endpoint was change from baseline in MG-ADL rating at Week 26 within the mixed inhabitants. Key secondary endpoints included change from baseline in QMG scores within the mixed research inhabitants; change from baseline in MG-ADL rating at Week 26 for the AChR+ cohort and individually the MuSK+ cohort; and alter from baseline in QMG rating at Week 26 for the AChR+ cohort and individually the MuSK+ cohort. Sufferers who entered the research taking a corticosteroid had been tapered all the way down to prednisone 5 mg a day, beginning at Week 4 to Week 24. The MINT trial additionally contains an non-compulsory three-year open-label remedy interval.
About Generalized Myasthenia Gravis (gMG)
Generalized myasthenia gravis (gMG) is a uncommon, power, B-cell-mediated autoimmune dysfunction that impairs neuromuscular communication and may trigger muscle weak spot, bother respiration, issue swallowing and impaired speech and imaginative and prescient. 1-4 Roughly 85% of sufferers with myasthenia gravis have the generalized type, or gMG. 4,5
The prevalence and incidence of gMG are growing worldwide. 5 There are between 80,000 and 100,000 sufferers with myasthenia gravis within the U.S. 6,7 Roughly 85% of sufferers with myasthenia gravis have detectable antibodies in opposition to AChR, and roughly 7% have detectable antibodies in opposition to MuSK. 8 World prevalence is estimated at 2-36 instances per 100,000. 9 The illness is extra incessantly seen in younger girls (age 20-30) and males aged 50 years and older. 5,9
B cells are central to the pathogenesis of gMG. The illness is regarded as primarily pushed by pathogenic CD19+ plasmablasts and plasma cells that concentrate on essential proteins within the neuromuscular junction. 1-3
