Insights

Medical Research Analyst

The recent trial results for upadacitinib contribute to a promising shift in the treatment landscape for giant cell arteritis (GCA), a condition that notably affects the elderly population. Unlike the broad application of steroids, which can carry significant side effects, the targeted approach of upadacitinib could offer a more favorable safety profile. It's important to understand that sustained remission is the absence of GCA signs and symptoms, coupled with a reduction in steroid usage, over a set period. The trial indicates a nearly 17% increase in sustained remission rates compared to the placebo group, which is statistically significant. The potential for upadacitinib to become the first oral treatment option for GCA challenges the current standard of care and may present a compelling case for regulatory approval. For investors, the commercial success of upadacitinib hinges on this approval and the subsequent market adoption should the drug's safety and efficacy be ratified by regulatory bodies.

Financial Analyst

The positive Phase 3 trial outcomes for upadacitinib hold substantial financial implications for AbbVie. With GCA primarily affecting individuals aged 70-80 and an increasing global elderly population, the market potential for an effective oral treatment is expanding. The current standard of care, which predominantly relies on steroids, presents unmet needs due to associated adverse effects. If upadacitinib gains approval, it could achieve a first-mover advantage in this niche market. It is essential to monitor the drug's progress through regulatory review, as approval could lead to a new revenue stream for AbbVie. The market's reaction to this will depend on the detailed data release at upcoming medical meetings and the assessment of the drug's commercial viability against competitors. From an investment perspective, potential FDA approval and market capture rates will be critical determinants of AbbVie's financial forecast and stock valuation.

Pharmaceutical Market Research Analyst

The treatment of GCA has historically been underserved and significant advancements such as upadacitinib's Phase 3 results could disrupt the current standard of care. In assessing the market impact, the focus will be on the drug's differentiation from existing steroid treatments. The safety profile aligning with indications approved by regulatory authorities may expedite the drug's acceptance among healthcare providers. However, market adoption will depend on several factors including insurance coverage, pricing and physician prescribing habits. The competitive landscape analysis, coupled with ongoing research, will shape the strategic positioning of upadacitinib in AbbVie's portfolio. The demographic trends suggest a growing patient pool, which, alongside a potential first-to-market advantage, may drive future growth. Investors should watch for market research data post-launch to gauge real-world uptake and adherence to the new treatment regimen.

−     Results from the Phase 3 SELECT-GCA study showed 46 percent of patients with giant cell arteritis (GCA) who were treated with upadacitinib (RINVOQ^®; 15 mg) with a 26-week steroid taper regimen achieved sustained remission from week 12 through week 52 compared to 29 percent of patients receiving placebo with a 52-week steroid taper regimen¹

NORTH CHICAGO, Ill., April 18, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced positive top-line results from SELECT-GCA, a Phase 3, multicenter, randomized, double-blind, placebo-controlled study, showing upadacitinib (RINVOQ^®; 15 mg, once daily) in combination with a 26-week steroid taper regimen achieved its primary endpoint of sustained remission^a from week 12 through week 52 in adults with giant cell arteritis (GCA). In this study, 46 percent of patients receiving upadacitinib 15 mg in combination with a 26-week steroid taper regimen achieved sustained remission compared to 29 percent of patients receiving placebo in combination with a 52-week steroid taper regimen (p=0.0019).¹

"Many people living with GCA continue to suffer from the potentially debilitating symptoms of this disease, with limited treatment options available to them," said Kori Wallace, M.D., Ph.D., vice president, global head of immunology clinical development, AbbVie. "These results demonstrate our relentless commitment to improving the lives of people living with immune-mediated diseases by developing new treatments where significant medical needs still exist."

GCA is an autoimmune disease that causes inflammation of the temporal and other cranial arteries, the aorta, and other large and medium arteries. GCA generally impacts elderly patients older than 50 years, most commonly between the ages of 70 and 80 years. Women have the highest risk of developing this disease, which can cause headache, jaw pain and changes in or loss of vision, including sudden and permanent loss of vision.²

Key secondary endpoints were also met, including a higher percentage of patients receiving upadacitinib 15 mg in combination with a 26-week steroid taper regimen achieved sustained complete remission^b from week 12 through week 52 compared to patients receiving placebo in combination with a 52-week steroid taper regimen (37 percent versus 16 percent; p<0.0001).¹ A lower percentage of patients experienced at least one disease flare through week 52 in the upadacitinib 15 mg group versus the placebo group (34 percent versus 56 percent; p=0.0014).¹ The study results also showed that upadacitinib 7.5 mg did not meet the primary or any of the secondary endpoints.¹

"I am encouraged by these results, which add to the body of evidence supporting the efficacy and safety profile of upadacitinib for the treatment of rheumatic diseases," said Daniel Blockmans, M.D., Ph.D., Department of General Internal Medicine, University Hospitals Gasthuisberg, Belgium, professor of medicine, KU Leuven, Belgium, and lead investigator of the SELECT-GCA trial. "Based on these results, upadacitinib has the potential to be the first oral treatment option for patients with GCA, a disease with inflammation of the large arteries that primarily impacts older people and has only one approved treatment to date³ commonly used with steroids." 

During the 52-week, placebo-controlled period, the safety profile of upadacitinib 15 mg was generally consistent with that observed in approved indications.¹ Upadacitinib 15 mg was generally well tolerated, with no new safety signals identified in this GCA population.¹ Discontinuations due to adverse events occurred in 15 percent of patients in the upadacitinib 15 mg group and 21 percent of patients in the placebo group.¹ In this study, the proportion of patients who experienced a serious adverse event was similar (23 percent in the upadacitinib 15 mg group and 21 percent in the placebo group).¹ Serious infections occurred in 6 percent of the upadacitinib 15 mg group and 11 percent of the placebo group.¹ Overall, the proportions of patients with incidence of malignancy excluding non-melanoma skin cancer and adjudicated venous thromboembolic events (VTEs) were balanced across both the upadacitinib 15 mg (2 percent and 3 percent, respectively) and placebo (2 percent and 4 percent, respectively) treatment groups.¹ There were no adjudicated major adverse cardiac events (MACE) in the upadacitinib 15 mg group compared to two events in the placebo group.¹ Four treatment-emergent deaths were reported, two in the placebo group and two in the upadacitinib 15 mg group.¹ Of the two treatment-emergent deaths in the upadacitinib 15 mg group, one was attributed to COVID-19, and the other was adjudicated as an unexplained cause.¹   

Full results across all treatment groups from the SELECT-GCA study will be presented at a future medical meeting. Use of upadacitinib in GCA is not approved and its safety and efficacy have not been evaluated by regulatory authorities.

^a Sustained remission is defined as having an absence of GCA signs and symptoms from week 12 through week 52 and adherence to the protocol-defined steroid taper over the course of the study term.

^b Sustained complete remission is defined as having an absence of GCA signs and symptoms from week 12 through week 52, adherence to the protocol-defined steroid taper, and normalization of both erythrocyte sedimentation rate (ESR) and high sensitivity C-reactive protein (hsCRP) from week 12 through week 52.

About SELECT-GCA 

SELECT-GCA (M16-852) was a Phase 3, multicenter, randomized, double-blind placebo-controlled study designed to evaluate the safety and efficacy of upadacitinib in 428 patients with GCA. The study consists of two periods. The first period, which is reported in this release, evaluated the efficacy of upadacitinib in combination with a 26-week corticosteroid taper regimen compared to placebo in combination with a 52-week corticosteroid taper regimen. In addition, the study assessed the safety and tolerability of upadacitinib in these patients. The second period will evaluate the safety and efficacy of continuing versus withdrawing upadacitinib in maintaining remission in participants who achieved sustained remission in the first period.¹ For more information regarding this study, please visit ClinicalTrials.gov (Identifier NCT03725202).

About Giant Cell Arteritis 

Giant cell arteritis (GCA), also known as temporal arteritis, is an autoimmune disease of medium and large arteries, characterized by granulomatous inflammation of the three-layered vessel wall, which affects temporal and other cranial arteries as well as the aorta and other large arteries.^2,4 GCA can cause headache, jaw pain, and changes in or loss of vision, including sudden and permanent loss of vision.² It is the most common vasculitis affecting adults in western countries.² Caucasian women over the age of 50 – most commonly between the ages of 70 and 80 years – have the highest risk of developing giant cell arteritis. Although women are more likely than men to develop GCA, research suggests that men are more likely to have ocular manifestations with their disease.⁵

IMPORTANT SAFETY INFORMATION

What is the most important information I should know about RINVOQ?

RINVOQ may cause serious side effects, including:

• Serious infections. RINVOQ can lower your ability to fight infections. Serious infections have happened while taking RINVOQ, including tuberculosis (TB) and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections. Your healthcare provider (HCP) should test you for TB before starting RINVOQ and check you closely for signs and symptoms of TB during treatment with RINVOQ. You should not start taking RINVOQ if you have any kind of infection unless your HCP tells you it is okay. If you get a serious infection, your HCP may stop your treatment until your infection is controlled. You may be at higher risk of developing shingles (herpes zoster).
• Increased risk of death in people 50 years and older who have at least 1 heart disease (cardiovascular) risk factor.
• Cancer and immune system problems. RINVOQ may increase your risk of certain cancers. Lymphoma and other cancers, including skin cancers, can happen. Current or past smokers are at higher risk of certain cancers, including lymphoma and lung cancer. Follow your HCP's advice about having your skin checked for skin cancer during treatment with RINVOQ. Limit the amount of time you spend in sunlight. Wear protective clothing when you are in the sun and use sunscreen.
• Increased risk of major cardiovascular (CV) events, such as heart attack, stroke, or death, in people 50 years and older who have at least 1 heart disease (CV) risk factor, especially if you are a current or past smoker.
• Blood clots. Blood clots in the veins of the legs or lungs and arteries can happen with RINVOQ. This may be life-threatening and cause death. Blood clots in the veins of the legs and lungs have happened more often in people who are 50 years and older and with at least 1 heart disease (CV) risk factor.
• Allergic reactions. Symptoms such as rash (hives), trouble breathing, feeling faint or dizzy, or swelling of your lips, tongue, or throat, that may mean you are having an allergic reaction have been seen in people taking RINVOQ. Some of these reactions were serious. If any of these symptoms occur during treatment with RINVOQ, stop taking RINVOQ and get emergency medical help right away.
• Tears in the stomach or intestines. This happens most often in people who take nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids. Get medical help right away if you get stomach-area pain, fever, chills, nausea, or vomiting.
• Changes in certain laboratory tests. Your HCP should do blood tests before you start taking RINVOQ and while you take it. Your HCP may stop your RINVOQ treatment for a period of time if needed because of changes in these blood test results.
