NEW YORK, November 16, 2020 (GLOBE NEWSWIRE) -- BeyondSpring (the “Company” or “BeyondSpring”) (NASDAQ: BYSI), a global biopharmaceutical company focused on the development of innovative cancer therapies, today announced positive topline data from its PROTECTIVE-2 Phase 3 registrational study showing that plinabulin in combination with pegfilgrastim met the primary endpoint with statistically significant improvement in the rate of prevention of Grade 4 neutropenia in Cycle 1 (31.5% vs 13.6%, p=0.0015), as well as achieving statistical significance in all key secondary endpoints, including duration of severe neutropenia (DSN) and absolute neutrophil count (ANC) nadir.
The PROTECTIVE-2 Phase 3 study is a double-blind, active-controlled, global study that enrolled a total of 221 patients. Patients in the trial were treated with docetaxel, doxorubicin and cyclophosphamide (TAC, Day 1 dose) in a 21-day cycle with plinabulin (40 mg, Day 1 dose) + pegfilgrastim (6 mg, Day 2 dose) versus a single dose of pegfilgrastim (6 mg, Day 2 dose). The primary efficacy endpoint was rate of prevention of Grade 4 neutropenia.
Plinabulin in combination with pegfilgrastim showed a statistically significant improvement compared to pegfilgrastim alone, with topline data summarized below. Data from all 221 patients were analyzed (combination arm n=111, pegfilgrastim arm n=110).
| • | Primary endpoint (Rate of prevention of Grade 4 neutropenia): 31.5% combo therapy vs. 13.6% pegfilgrastim monotherapy, 95% CI 17.90 (7.13, 28.66), p = 0.0015 |
|---|---|
| • | Key secondary endpoints: |
| --- | --- |
| o | DSN Cycle 1 Day 1-8 (ANC < 0.5 x 10^9^ cells/L): p = 0.0065, |
| --- | --- |
| o | DSN Cycle 1: p = 0.03 |
| --- | --- |
| o | Mean ANC nadir Cycle 1 (x 10^9^ cells/L): p = 0.0002 |
| --- | --- |
| o | Duration of profound neutropenia Cycle 1 (ANC < 0.1 x 10^9^ cells/L): p = 0.0004, |
| --- | --- |
According to literature, profound neutropenia leads to 80% patient death in first week of infection^1^, and 48% febrile neutropenia, or FN, and 50% infection^2^.
| • | Safety data: |
|---|---|
| o | Lower Grade 4 adverse event (AE) frequency (58.6%) for combination compared to 80.0% in pegfilgrastim monotherapy |
| --- | --- |
“These data clearly demonstrate the potential for this combination to offer superior therapy compared to standard of care in the prevention of CIN,” said Douglas W. Blayney, M.D., Professor of Medicine at the Stanford University School of Medicine and the global principal investigator for plinabulin's CIN studies. “With current therapy, Grade 4 neutropenia still occurs in more than 80% of patients after chemotherapy, primarily in Week 1 after chemotherapy, which increases Emergency Room visits and hospitalizations due to infection and febrile neutropenia. Grade 4 neutropenia is also associated with increased mortality and reduced long-term survival due to reduction, delay, or interruption of chemotherapy. I would like to thank the participating patients, their families and the BeyondSpring team for their dedicated work to advance this combination therapy for the prevention of CIN in chemotherapy patients.”
Ramon Mohanlal, M.D., Ph.D., Chief Medical Officer and Executive Vice President of Research and Development at BeyondSpring noted, “We are pleased to have received Breakthrough Therapy designation from both the U.S. FDA and China NMPA for the plinabulin combination in CIN, underscoring the unmet medical need and potential benefit of the combination. We are working with regulatory agencies on the NDA submission, which is expected in Q1 2021 and have also begun preparation for commercialization. In addition to Plinabulin being developed as a treatment option for the prevention of CIN, it is also being investigated as a direct anticancer agent in a global Phase 3 trial of plinabulin + docetaxel for non-small cell lung cancer (NSCLC), with final data read-out in 1H 2021.”
Conference Call and Webcast Information
BeyondSpring’s management will host a conference call and webcast today at 8:30 a.m. Eastern Time.

About Plinabulin in PROTECTIVE-2 (Study 106) CIN Study
The Phase 3 portion of PROTECTIVE-2 is a double-blind and active controlled global study. It was designed to evaluate the safety and efficacy in breast cancer, treated with docetaxel, doxorubicin and cyclophosphamide (TAC, Day 1 dose) in a 21-day cycle with plinabulin (40 mg, Day 1 dose) + Pegfilgrastim (6 mg, Day 2 dose) versus a single dose of Pegfilgrastim (6 mg, Day 2 dose). TAC is an example of high febrile neutropenia risk chemotherapy; all G-CSF biosimilar studies use TAC in the pivotal studies.
Plinabulin and G-CSFs such as Pegfilgrastim are believed to have complementary mechanisms in preventing chemotherapy-induced neutropenia (CIN). This is a superiority study in CIN efficacy in the rate of prevention of Grade 4 neutropenia, comparing the combination head-to-head against Pegfilgrastim alone. Literature shows that the Grade 4 neutropenia rate for TAC and Pegfilgrastim at 6 mg is 83 to 93 percent, which presents severe unmet medical needs.
The absolute neutrophil count (ANC) data, which are used to calculate these endpoints, were obtained through central laboratory assessments by Covance Bioanalytical Methods using standardized and validated analytical tests. Covance was the clinical contract research organization (CRO) for patient recruitment and monitoring of global sites for this study.
About Chemotherapy Induced Neutropenia (CIN)
Patients receiving chemotherapy typically develop CIN, a severe side effect that increases the risk of infection with fever (also called febrile neutropenia, or “FN”), which necessitates ER/hospital visits. The updated National Comprehensive Cancer Network (NCCN) guidelines expanded the use of prophylactic G-CSFs, such as Pegfilgrastim, from only high risk patients (chemo FN rate >20%) to intermediate risk patients (FN rate between 10-20%) to avoid hospital/ER visits during the COVID-19 pandemic. The revision of the NCCN guidelines effectively increases the addressable market of patients who may benefit from treatment with plinabulin, if approved, to approximately 440,000 cancer patients in the U.S. annually. Plinabulin is designed to provide protection against the occurrence of CIN and its clinical consequences in week 1, or early onset action after chemotherapy.
About Plinabulin
Plinabulin, BeyondSpring’s lead asset, is an investigational differentiated immune and stem cell modulator. Plinabulin is currently in late-stage clinical development to increase overall survival in cancer patients, as well as to alleviate CIN. Plinabulin had received Breakthrough Therapy Designation from China NMPA in CIN. The U.S. FDA granted Breakthrough Therapy designation to plinabulin for concurrent administration with myelosuppressive chemotherapeutic regimens in patients with non-myeloid malignancies for the prevention of chemotherapy-induced neutropenia (CIN). The durable anticancer benefits of plinabulin observed to date have been associated with its effect as a potent antigen-presenting cell (APC) inducer (through dendritic cell maturation) and T-cell activation (Chem and Cell Reports, 2019). Plinabulin’s CIN data highlight the ability to boost the number of hematopoietic stem / progenitor cells (HSPCs), or lineage-/cKit+/Sca1+ (LSK) cells in mice. Effects on HSPCs could explain the potential ability of plinabulin to not only treat CIN with a rapid onset, but also to reduce chemotherapy-induced thrombocytopenia and increase circulating CD34+ cells in patients.
Plinabulin currently is in an Expanded Access Program in the U.S.
