Incyte Announces First Data from REACH3 Trial Showing Ruxolitinib (Jakafi®) Significantly Improved Outcomes in Patients with Steroid-Refractory or Steroid-Dependent Chronic Graft-Versus-Host Disease
December 4, 2020– Results of REACH3 trial also demonstrate significant improvements in failure-free survival (FFS) and patient-reported symptoms1
– Findings from the study are being presented at ASH 2020, and complement previously-reported positive results for Jakafi in steroid-refractory acute graft-versus-host disease (GVHD)2
– Chronic GVHD is a life-threatening complication of stem cell transplants and half of patients become steroid refractory/dependent3,4
– Investor conference call and webcast scheduled for Monday, December 7, 2020 at 10:00 a.m. ET (7:00 a.m. PT)
WILMINGTON, Del.–(BUSINESS WIRE)–$INCY #ASH20–Incyte (Nasdaq:INCY) today announced that detailed results from the pivotal Phase 3 REACH3 study demonstrate Jakafi® (ruxolitinib) significantly improved outcomes across a range of efficacy measures in patients with steroid-refractory or steroid-dependent chronic graft-versus-host disease (GVHD) compared to best available therapy (BAT)1. The results of REACH3, the first successful, randomized Phase 3 trial in chronic GVHD, were highlighted in a press briefing today and will be presented during the 62nd American Society of Hematology Annual Meeting & Exposition (ASH 2020). REACH3 is jointly sponsored by Incyte and Novartis.
“The results from this large, randomized study further emphasize the role Jakafi can play as a meaningful option for patients with chronic GVHD, for whom new treatments are urgently needed,” said Peter Langmuir, M.D., Group Vice President, Oncology Targeted Therapies, Incyte. “These data are important for patients living with GVHD and their physicians as they represent the continued success of Jakafi in the chronic form of the disease, a historically difficult-to-treat condition.”
In REACH3, patients treated with Jakafi achieved significantly greater overall response rate (ORR) compared to BAT (49.7% vs. (Read more…) 25.6%; p<0.00015) at Week 24, the primary endpoint of the study6. Jakafi also demonstrated statistically significant and clinically meaningful improvements in key secondary endpoints:
- Patients receiving Jakafi had a significant improvement in failure-free survival (FFS; defined as time to the earliest recurrence of the underlying disease, the start of new systemic treatment for chronic GVHD, or death) versus patients receiving BAT (median FFS not yet reached vs. 5.7 months; hazard ratio, 0.37, 95% CI, 0.27-0.51; p<0.0001)1.
- Patients treated with Jakafi also had greater improvements in patient-reported symptoms than those treated with BAT (24.2% vs. 11.0%; p=0.0011), as measured by the rate of responders who achieved a reduction of ≥ 7 points of total symptom score (TSS) from baseline of the modified Lee Symptom Score (mLSS)1.
- Additionally, best overall response (BOR) rate, defined as any response up to week 24, was achieved in 76.4% of patients in the Jakafi arm compared to 60.4% in the BAT arm (odds ratio [OR], 2.17; 95% CI, 1.34-3.52). The median duration of response was 6.2 months in the BAT arm, but was not yet reached in the Jakafi arm1.
No new safety signals were observed in REACH3, and adverse events (AEs) attributable to treatment were consistent with the known safety profile of Jakafi. The most common AEs in the Jakafi vs. BAT arms were anemia (29.1% vs. 12.7%), hypertension (15.8% vs. 12.7%) and pyrexia (15.8% vs. 9.5%). While 37.6% and 16.5% of patients required Jakafi and BAT dose modifications, respectively, the number of patients who discontinued treatment due to AEs was low (16.4% and 7%, respectively). Mortality rates were similar across treatment arms (19% vs. 16% BAT)1. Deaths reported as primarily due to chronic GVHD were slightly higher for Jakafi.
“The damaging and sometimes deadly effects of chronic GVHD following stem cell transplant present significant treatment challenges, particularly for the nearly half of patients who do not adequately respond to steroid treatment,” said Dr. Robert Zeiser, University Hospital Freiburg, Department of Haematology, Oncology and Stem Cell Transplantation, Freiburg, Germany. “Based on the compelling REACH3 results, we now have a potential new standard of care for these patients.”
GVHD is a condition that can occur after an allogeneic stem cell transplant (the transfer of stem cells from a donor) where the donated cells initiate an immune response and attack the transplant recipient’s organs, leading to significant morbidity and mortality. There are two major forms of GVHD: acute, which occurs within 100 days of transplant, and chronic, which occurs after 100 days of transplant3. GVHD can affect multiple organ systems including the skin, gastrointestinal (digestive) tract and liver.
In 2019, Jakafi® (ruxolitinib) was approved by the U.S. Food and Drug Administration for the treatment of steroid-refractory acute GVHD in adult and pediatric patients 12 years and older, based on the positive results of the Phase 2 REACH1 trial6. Jakafi is marketed by Incyte in the U.S.; ruxolitinib (Jakavi®) is licensed to Novartis ex-U.S.
About REACH3
REACH3 (NCT03112603), a randomized, open-label, multicenter Phase 3 study sponsored by Novartis and conducted in collaboration with and co-funded by Incyte, is evaluating the safety and efficacy of ruxolitinib compared with best available therapy in patients with steroid-refractory chronic GVHD.
The primary endpoint is overall response rate (ORR) at Day 1 of the Cycle 7 (Day 168) visit, defined as the percentage of participants demonstrating a complete or partial response. Secondary endpoints include change in the modified Lee chronic GVHD symptom scale score at Day 1 of Cycle 7, rate of failure-free survival (FFS) up to 36 months, best overall response (BOR), duration of response (DoR), overall survival (OS), among others.
