Since 2018, the clinical results of HQP1351 have been selected for oral presentations at American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting for three years in a row. At present, a New Drug Application (NDA) for HQP1351 has been submitted in China, and the application was subsequently granted the Priority Review status. Moreover, HQP1351 was cleared by the US Food and Drug Administration (FDA) to enter a Phase Ib clinical study, and was subsequently granted an Orphan Drug Designation (ODD) and a Fast Track Designation (FTD) by the US FDA.

About Lisaftoclax (APG-2575)

APG-2575 is a novel, orally administered small-molecule Bcl-2‒selective inhibitor being developed by Ascentage Pharma. APG-2575 is designed to treat hematologic malignancies and solid tumors by selectively blocking antiapoptotic protein Bcl-2 to restore the normal apoptosis process in cancer cells. APG-2575 is the first China-developed Bcl-2 inhibitor entering clinical development in China.

At present, APG-2575 has been cleared and approved to enter multiple Phase Ib/II studies in the US, China, Europe, and Australia, and is being developed globally for the treatment of multiple hematologic malignancies including chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML), and breast cancer. To date, APG-2575 has been granted five ODDs by the US FDA for the treatment of Waldenström macroglobulinemia (WM), CLL, multiple myeloma (MM), AML, and follicular lymphoma (FL).

About HALPRYZA (rituximab biosimilar injection)

HALPRYZA,a rituximab biosimilar injection, is a recombinant human/murine chimeric monoclonal antibody drug co-developed and co-commercialized by Innovent and Eli Lilly and Company. Rituximab binds to the CD20 antigen on the surface of B lymphocytes and mediates complement-dependent cytotoxicity (CDC) and antibody-dependent cellular cytotoxicity (ADCC). Normal and malignant B cells are targeted for destruction by the antibody, thereby achieving anti-tumor and immunosuppressive therapeutic effects. In China, HALPRYZA is approved by National Medical Products Administration (NMPA) for diffuse large b cell lymphoma (DLBCL), follicular lymphoma (FL), and CLL.

About letaplimab (IBI188)

IBI188 (letaplimab), developed by Innovent Biologics, is a recombinant fully humanized IgG4 monoclonal antibody targeting CD47. CD47 is a transmembrane protein that blocks phagocytosis of macrophage by binding to the signaling regulatory protein (SIRP) on the surface of macrophage, to send a "don’t eat me" signal. After blocking this myeloid checkpoint, IBI188 (letaplimab) enhanced phagocytosis of tumor cells and cross-activated T cells. Preclinical data showed that IBI188 (letaplimab) had clear target, clear mechanism of action and significant efficacy. Phase 1a clinical data showed that the escalation of all the preset doses has completed, with the highest exploratory dose of 30mg/kg QW. No dose-limiting toxicity occurred in each dose group, and IBI188 (letaplimab) was well tolerated generally.

TST005 is the second bi-functional anti-PD-L1 and TGF-β trap fusion protein entering the global clinical stage. It simultaneously targets two immuno-suppressive pathways, transforming growth factor -β (TGF-β) and programmed cell death ligand-1 (PD-L1), that are commonly used by cancer cells to evade the immune system. TST005 consists of a high affinity PD-L1 antibody fused with an engineered TGF-β Receptor Type II protein in its C-terminal. TST005 lacks FcR binding activity and thus has reduced FcR mediated killing of PD-L1 expressing effector T cells. TST005’s high PD-L1 binding activity and enhanced TGF-β trap stability enables the targeted delivery of TGF-β trap into PD-L1 expressing tumors, thereby minimizing off-target toxicities of systemic inhibition of TGF-β signaling. TST005 displayed potent activity in vitro in reversing TGF-β induced T-cell suppression. In multiple syngeneic tumor models, TST005 induced significant increase of CD8 T-cell infiltration into PD-L1 expressing tumors and displayed dose-dependent tumor growth inhibition in tumor model not sensitive to PD-(L)1 treatment due to high level TGF-β. TST005 is well tolerated in non-human primates and displayed a linear PK profile. TST005 is a potential novel bi-functional immunotherapy candidate with improved therapeutic window.

"TST005 has potential application for the treatment of a large number of tumor types. It is expected to be effective in the patient populations who are either naïve or progressed after treatment with PD-(L)1 inhibitor." said Dr. Michael Shi, EVP, Head of Global R&D and CMO of Transcenta, "TST005 will be one of the company’s key competitive products, considering that there are huge worldwide unmet needs in patients who failed checkpoint inhibitor therapies, by targeting PD-L1/TGF-β pathways."

"Primary and acquired resistance to immune checkpoint inhibitors represent a significant unmet need in cancer treatment." said Anthony W. Tolcher, M.D., FRCPC, FACP, Medical Oncologist, Co-founder of NEXT Oncology and current study’s investigator. "TST005 demonstrated potent antitumor efficacy in multiple pre-clinical models while maintaining wide safety margins, and I look forward to evaluating this novel bi-functional antibody in patients with advanced solid tumors."

Incyte Announces Positive Phase 3 REACH3 Study Data Published in NEJM for Ruxolitinib (Jakafi®) in Chronic Graft-Versus-Host Disease

On July 14, 2021 Incyte (Nasdaq:INCY) reported that positive data from the Phase 3 REACH3 study have been published in The New England Journal of Medicine (NEJM) demonstrating that treatment with ruxolitinib (Jakafi) resulted in significantly improved outcomes in patients with steroid-refractory or steroid-dependent chronic graft-versus-host disease (GVHD) compared to best available therapy (BAT)1 (Press release, Incyte, JUL 14, 2021, View Source [SID1234584854]). The study’s main findings, previously presented at the 62nd American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting, were published along with new subgroup analyses showing favorable overall response rate (ORR) at Week 24 for ruxolitinib across all major subgroups, including baseline individual organ involvement1. REACH3 is jointly sponsored by Incyte and Novartis.

"Results from the REACH3 study published in NEJM are extremely compelling and underscore the potential benefits ruxolitinib can offer appropriate patients facing the serious complications associated with chronic GVHD," said Peter Langmuir, M.D., Group Vice President, Oncology Targeted Therapies, Incyte. "At Incyte, we remain committed to advancing our research and understanding of this complex disease, and will continue to work closely with the FDA to bring this innovative treatment to chronic GVHD patients, who currently have limited treatment options."

The study found that treatment with ruxolitinib led to significant improvements in ORR at Week 24 (49.7% vs. 25.6%; odds ratio [OR], 2.99; P<0.001i), the primary endpoint of the study1. Also, best overall response (BOR) rate at any time up to Week 24 was achieved in 76.4% of patients in the ruxolitinib arm compared to 60.4% of patients in the BAT arm (OR, 2.17; 95% CI, 1.34-3.52)1. Ruxolitinib also demonstrated statistically significant and clinically meaningful improvements in key secondary endpoints1:

Patients on ruxolitinib achieved longer failure-free survival (FFS) than patients receiving BAT (median FFS not yet reached vs. 5.7 months; hazard ratio, 0.37; 95% CI, 0.27 to 0.51; P<0.0001).
Patients treated with ruxolitinib also had greater improvements in self-reported symptoms compared to BAT1 (modified Lee Symptom Scale [mLSS] responder rate: 24.2% vs. 11.0%; OR, 2.62; P=0.001)ii.
In addition, a new subgroup analysis included in the publication found that patients on ruxolitinib had better outcomes regardless of the individual organs affected at baseline1.

No new safety signals were observed in REACH3, and adverse events (AEs) attributable to treatment were consistent with the known safety profile of ruxolitinib1. The most common AEs of grade 3 or higher in the ruxolitinib vs. BAT arms were thrombocytopenia (15.2% vs. 10.1%), anemia (12.7% vs. 7.6%), neutropenia (8.5% vs. 3.8%) and pneumonia (8.5% vs. 9.5%). While 37.6% and 16.5% of patients required ruxolitinib and BAT dose modifications due to AEs, respectively, the percentage of patients who discontinued treatment due to AEs was 16.4% in the ruxolitinib arm vs. 7% in the BAT arm1. Mortality rates were similar across treatment arms (18.8% in the ruxolitinib arm vs. 16.5% in the BAT arm)1. Deaths reported as primarily due to chronic GVHD complications and/or its treatment were higher in the ruxolitinib vs. BAT arms (13.3% vs. 7.9%, respectively)1.

"Patients with chronic GVHD can experience severe and life-threatening symptoms in different organs around the body, which makes the disease more difficult to treat and increases the risk of poor outcomes," said Dr. Robert Zeiser, University Hospital Freiburg, Department of Haematology, Oncology and Stem Cell Transplantation, Freiburg, Germany. "With these new results from REACH3, we can see more clearly the potential benefits of ruxolitinib for patients with chronic GVHD who have not adequately responded to first-line steroids."

The REACH3 data serve as the basis for the Company’s supplemental New Drug Application (sNDA) for ruxolitinib for the treatment of steroid-refractory chronic GVHD in adult and pediatric patients 12 years and older, which was accepted for review by the U.S. Food and Drug Administration (FDA) and has a Prescription Drug User Fee Act (PDUFA) target action date of September 22, 2021.

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 generally occurs within 100 days of transplant, and chronic, which generally occurs more than 100 days after transplant2. GVHD can affect multiple organ systems including the skin, gastrointestinal (digestive) tract and liver.

In 2019, Jakafi (ruxolitinib) was approved by the FDA 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 trial4. Jakafi is marketed by Incyte in the U.S.; ruxolitinib (Jakavi) is licensed to Novartis ex-U.S. Outside of the U.S., Novartis regulatory submissions for acute and chronic GVHD are underway.

The NEJM publication of the REACH3 results is available online.

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. For more information about the study, please visit View Source

About REACH

The REACH clinical trial program evaluating ruxolitinib in patients with steroid-refractory GVHD includes the randomized pivotal Phase 3 REACH2 and REACH3 trials, conducted in collaboration with Novartis. Positive data from the Phase 3 REACH2 study evaluating the safety and efficacy of ruxolitinib compared with best available therapy in patients with steroid-refractory acute GVHD were previously published in The New England Journal of Medicine.

The REACH program was initiated with the Incyte-sponsored REACH1 trial, a prospective, open-label, single-cohort, multicenter, pivotal Phase 2 trial (NCT02953678) evaluating ruxolitinib in combination with corticosteroids in patients with steroid-refractory grade II-IV acute GVHD.
