INDIANAPOLIS, IN, USA I September 30, 2021 I Eli Lilly and Company (NYSE: LLY) and Incyte (NASDAQ: INCY) announced today detailed results from two pivotal Phase 3 trials (BRAVE-AA1 and BRAVE-AA2), which found once-daily OLUMIANT® (baricitinib) 4-mg was superior to placebo in achieving significant scalp hair regrowth as early as 24 weeks in adults with severe alopecia areata (AA) as defined by ≥50% scalp hair loss at baseline.
Significant improvements in scalp hair regrowth compared to placebo were achieved at 36 weeks for patients taking OLUMIANT 2-mg and 4-mg oral doses, as previously disclosed in topline findings from BRAVE-AA1 and BRAVE-AA2 earlier this year. In both studies, a greater proportion of patients taking OLUMIANT 4-mg compared to placebo also achieved full regrowth or regrowth with minimal gaps in coverage of eyebrow and eyelash hair at 36 weeks, which were key secondary endpoints of the studies.
These results, along with safety data in adult patients with moderate to severe atopic dermatitis (AD), are being presented virtually at the 30th European Academy of Dermatology and Venerology (EADV) Congress, taking place from Sept. 29-Oct. 2, 2021.
Alopecia areata is a widely misunderstood, autoimmune disease that can cause extreme and patchy hair loss on the scalp, face and other areas of the body, along with emotional distress and psychosocial effects. OLUMIANT has received Breakthrough Therapy designation from the U.S. Food and Drug Administration (FDA) for the treatment of AA. Lilly plans to submit a supplemental New Drug Application (sNDA) to the FDA for OLUMIANT in AA in the second half of 2021.
OLUMIANT Demonstrated Improvement in Scalp, Eyelash and Eyebrow Hair Regrowth in Patients with AA in Two Phase 3 Trials
In BRAVE-AA1 and BRAVE-AA2, the first completed, randomized, double-blind, placebo-controlled Phase 3 trials for AA, 598 and 490 patients, respectively, underwent 36 weeks of treatment. Both studies included adults with severe AA, defined as a Severity of Alopecia Tool (SALT) score ≥50 (those with ≥50% scalp hair loss). At baseline, the participants had a mean SALT score of 85.5 (85.5% scalp hair loss, or 14.5% scalp hair coverage).
Across treatment groups, the average age of participants was 37.5 years old, and they had lived with AA for a mean of 12.2 years since first experiencing symptoms, with the onset for hair loss occurring at approximately age 25.
In BRAVE-AA1, statistically significant improvement in scalp hair regrowth occurred as early as 16 weeks among patients treated with OLUMIANT 4-mg and 24 weeks with OLUMIANT 2-mg, compared to placebo. At 16 weeks, nearly 1 in 5 patients (18.5%, n=52) taking OLUMIANT 4-mg achieved 80 percent or more scalp hair coverage (as measured by a SALT score ≤20) as compared to placebo (4.2%, n=8, p≤0.001). At 24 weeks, 1 in 10 patients (11.4%, n=21) taking OLUMIANT 2-mg achieved 80% or more scalp hair coverage as compared to placebo (4.8%, n=9, p=0.013).
In BRAVE-AA2, statistically significant improvement occurred as early as 24 weeks for patients treated with OLUMIANT 4-mg, with more than 1 in 4 patients (28.2%, n=66) reaching 80% or more scalp hair coverage as compared to placebo (1.3%, n=2, p≤0.001).
Across both studies at 36 weeks – the study's primary endpoint – 1 out of 3 patients treated with OLUMIANT 4-mg (BRAVE-AA1=35.2% [n=99]; BRAVE-AA2=32.5% [n=76]) and approximately 1 out of 5 patients treated with OLUMIANT 2-mg (BRAVE-AA1=21.7% [n=40]; BRAVE-AA2=17.3% [n=27]) achieved 80% or more scalp hair coverage, compared to 5.3% of patients taking placebo (n=10) and 2.6% (n=4) in BRAVE-AA1 and BRAVE-AA2, respectively (p≤0.001 for all comparisons to placebo).
Achievement of full regrowth or regrowth with minimal gaps in eyebrow and eyelash hair was also seen at 36 weeks with OLUMIANT 4-mg for 1 in 3 patients who at baseline had significant gaps or no notable eyebrows, as compared to patients taking placebo (BRAVE-AA1 eyebrow=31.4% [n=59]; BRAVE-AA1 eyelash=33.5% [n=56]; BRAVE-AA1 eyebrow placebo=3.2% [n=4]; BRAVE-AA1 eyelash placebo=3.1% [n=3]; BRAVE-AA2 eyebrow=34.8% [n=56]; BRAVE-AA2 eyelash=34.3% [n=48]; BRAVE-AA2 eyebrow placebo=4.5% [n=5]; BRAVE-AA2 eyelash placebo=5.6% [n=5]). This was measured by Clinician-Reported Outcome (ClinRO) Measure for Eyebrow Hair Loss™ and ClinRO Measure for Eyelash Hair Loss™ scores of patients achieving eyebrow and eyelash hair loss scores of 0 or 1 (full coverage or minimal gaps) with a ≥2-point improvement from baseline at 36 weeks, respectively, compared to placebo (p≤0.001 for all comparisons to placebo).
Statistically significant eyebrow regrowth results (19.1%, n=26, p≤0.001) were also found for OLUMIANT 2-mg in BRAVE-AA1 at 36 weeks, but not in BRAVE-AA2. Eyelash results were not statistically significant with OLUMIANT 2-mg in either study.
The safety profile of OLUMIANT was consistent with previously-published safety data, and no new safety signals were observed in the 36-week duration of these clinical trials. Few patients discontinued treatment due to adverse events (2.6% or less across both studies and doses), and the majority of treatment-emergent adverse events were mild or moderate in severity. The most commonly reported adverse events (≥5% in any treatment group in BRAVE-AA1 or BRAVE-AA2) included: upper respiratory tract infections, headache, acne, urinary tract infection and increases in blood markers related to the muscle.

"These findings are promising for patients with severe alopecia areata, as they support the potential for OLUMIANT to help patients regrow hair on the scalp, eyebrows and eyelashes," said Brett King, M.D., Ph.D., F.A.A.D., associate professor of dermatology at Yale University School of Medicine and lead author of these analyses. "Because there are no approved systemic therapies for alopecia areata, there is significant unmet need and health care providers and patients eagerly await approved treatment options for this disease."
Tolerability of OLUMIANT Was Further Demonstrated for Acne, Headache, and Gastrointestinal (GI) Events in Pooled Analysis Across Eight Studies of 2,500 Patients with AD
In a pooled analysis across eight studies, tolerability outcomes for acne, headache and GI adverse events (diarrhea, abdominal pain, nausea, vomiting and constipation) were evaluated in more than 2,500 adult patients with moderate to severe atopic dermatitis (AD) taking OLUMIANT 2-mg and 4-mg once daily.
Among those patients treated with OLUMIANT, 2.9% of patients (n=74/2,531) had an adverse event of acne and 6.6% had an adverse event of headache (n=166/2,531). The most common gastrointestinal events were diarrhea (3.1% [n=78/2,531]) and nausea (1.9% [n=49/2,531]). Most of these events were mild to moderate in severity. The number of patients with adverse events that were assessed as severe was low, with 10 patients (~0.4%) reporting severe adverse events (4 due to headache, 2 due to diarrhea, 1 due to abdominal pain, 1 due to upper abdominal pain, 1 due to nausea and 1 due to vomiting). A total of 6 patients (~0.2%) had temporary study interruptions (4 due to headache, 1 due to vomiting and 1 due to abdominal pain), and 5 patients (~0.2%) permanently discontinued (2 due to headache, 1 due to nausea and 2 due to abdominal pain) for any of these events.

"OLUMIANT has one of the largest and longest sets of available safety data in the JAK inhibitor class, spanning approximately 19,000 patient years in a period of over nine years across the clinical development program," said Lotus Mallbris, M.D., Ph.D., vice president of immunology development and U.S. and global medical affairs at Lilly. "We are encouraged that these data presented at EADV reinforce OLUMIANT's potential to be a breakthrough treatment for people suffering from significant hair loss due to alopecia areata."
About The Studies
- Efficacy and Safety of Baricitinib in Adults with Alopecia Areata: Phase 3 Results from Two Randomized Controlled Trials (BRAVE-AA1 and BRAVE-AA2)
- In BRAVE-AA1 and BRAVE-AA2, respectively, 654 and 546 patients were randomized, and 598 (91.4%) and 490 (89.7%) completed 36 weeks of treatment. In both BRAVE-AA1 and BRAVE-AA2, adults with severe AA at screening and baseline (defined as Severity of Alopecia Tool [SALT] score ≥50) were randomized 3:2:2 to once-daily OLUMIANT 4-mg, 2-mg or placebo.
- The primary endpoint was the proportion of patients achieving SALT score ≤20 (≤20% scalp hair loss or ≥80% hair coverage) at 36 weeks. Key secondary outcomes included the proportions of patients achieving ClinRO Measure for Eyebrow Hair Loss™ and ClinRO Measure for Eyelash Hair Loss™ scores of 0 or 1 (full coverage or minimal gaps) with ≥2-point improvements from baseline at Week 36 (among those with baseline scores ≥2 [significant gaps to no notable hair]).
- Data were censored after treatment discontinuation or if collected remotely due to the COVID-19 pandemic. Treatment comparisons were analyzed using logistic regression with non-responder imputation applied to missing data.
- Pooled Analysis of Baricitinib Tolerability in Patients with Atopic Dermatitis in Relation to Acne, Headache, and Gastrointestinal Events From 8 Clinical Trials
- This pooled analysis included patient-level safety data from eight clinical trials, including six double-blinded, randomized, placebo-controlled studies, one double-blinded, randomized, long-term extension study and one open-label, long-term extension study. A total of 2,531 patients were given OLUMIANT for 2,247 patient-years.
- Outcomes are reported in three analysis sets: placebo-controlled, 2-mg – 4-mg extended, and all-OLUMIANT AD. Tolerability outcomes included the common treatment-emergent adverse events of acne, headache, and GI events (diarrhea, nausea, vomiting, constipation, and abdominal pain). The proportion of patients with events and adjusted incidence rates were calculated along with analysis of severity, onset and duration of events.
OLUMIANT is also being investigated for the treatment of adults with systemic lupus erythematosus, juvenile idiopathic arthritis, and COVID-19 (outside of Japan). AA is the second potential treatment indication in dermatology for OLUMIANT.
OLUMIANT, a once-daily, oral JAK inhibitor was discovered by Incyte and licensed to Lilly. It is approved in the U.S. and more than 75 countries as a treatment for adults with moderate to severe rheumatoid arthritis and is approved in more than 40 countries, including the European Union and Japan, for the treatment of adult patients with moderate to severe atopic dermatitis who are candidates for systemic therapy. Marketing authorization for the treatment of hospitalized patients with COVID-19 has been granted for OLUMIANT in multiple countries including Japan and Switzerland. The U.S. FDA-approved labeling for OLUMIANT includes a Boxed Warning for Serious Infections, Malignancy, and Thrombosis. See the full Prescribing Information here. Baricitinib is also being investigated in alopecia areata (AA), juvenile idiopathic arthritis (JIA) and systematic lupus erythematosus (SLE).
In December 2009, Lilly and Incyte announced an exclusive worldwide license and collaboration agreement for the development and commercialization of baricitinib and certain follow-on compounds for patients with inflammatory and autoimmune diseases.
Indication and Usage for OLUMIANT (baricitinib) tablets (in the United States) for RA patients
OLUMIANT® (baricitinib) 2 mg is indicated for the treatment of adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response to one or more tumor necrosis factor (TNF) antagonist therapies. Limitation of Use: Not recommended for use in combination with other JAK inhibitors, biologic disease-modifying antirheumatic drugs (DMARDs), or with potent immunosuppressants such as azathioprine and cyclosporine.

About Alopecia Areata
Alopecia areata (AA) is an autoimmune disease that causes patchy hair loss on the scalp, face and sometimes on other areas of the body that can progress. AA often first appears during childhood and can be different for everyone who has it. People of all ages, males/females and all ethnic groups can develop AA.
About Atopic Dermatitis
Atopic dermatitis (AD), or atopic eczema, is a chronic, relapsing skin disease characterized by intense itching, dry skin and inflammation that can be present on any part of the body. AD is a heterogeneous disease both biologically and clinically, and may be characterized by a highly variable appearance in which flares occur in an unpredictable manner.
Moderate-to-severe AD is characterized by intense itching, which leads to an itch-scratch cycle that further damages the skin. Like other chronic inflammatory diseases, AD is immune-mediated and involves a complex interplay of immune cells and inflammatory cytokines.
