Senhwa Biosciences Receives US FDA ‘Study May Proceed’ Letter to Treat BRCA2+ or PALB2+ Solid Tumors With CX-5461

On December 23, 2020 Senhwa Biosciences, Inc. (TPEx: 6492), a clinical-stage biopharmaceutical company focused on next-generation DNA Damage Response (DDR) therapeutics for the treatment of cancer, reported that it has received a "Study May Proceed" letter from the US Food and Drug Administration (FDA) to begin a Phase Ib study evaluating CX-5461, a first-in-class G-quadruplex stabilizer, to treat solid tumors with BRCA2 or PALB2 mutations (Press release, Senhwa Biosciences, DEC 23, 2020, View Source [SID1234573240]).

"The FDA’s approval of our Phase Ib clinical trial application for testing CX-5461 in patients with BRCA2 or PALB2 mutations is an important milestone and marks a new paradigm in the treatment of cancers with specific pathogenic mutations," stated Dr. John Soong, the Chief Medical Officer of Senhwa Biosciences.

In 2016, Canadian Cancer Trial Group (CCTG), a recipient of the Stand Up to Cancer’s Dream Team Grant selected CX-5461 to study in their Phase I trial. In the CCTG Trial, CX-5461 demonstrated clinically significant and lasting benefits in patients with specific tumor biomarkers that were resistant to platinum and other chemotherapeutics. This new Phase Ib trial will occur in both the US and Canada, and study endpoints include a re-confirmation of the efficacy signal. This trial is currently under review with Health Canada.

CX-5461 was recently named as a PCF (Prostate Cancer Foundation)-Pfizer Global Challenge Award recipient. Specifically, it will be used together with Pfizer’s PARP inhibitor (PARPi), Talazoparib, to evaluate the combined therapeutic potential in treating prostate cancer. For American men, prostate cancer is the second-leading cause of cancer death. Due to a DNA repair defect, BRCA1/2 deficient tumor cells are more sensitive to PARPi through the mechanism of synthetic lethality; however, PARPi resistance is commonly seen in clinical use. More than 40% of BRCA1/2-deficient patients fail to respond to PARPi.

"CX-5461 has proven human efficacy across certain tumor types by accelerating dsDNA breaks. We believe CX-5461 has great potential as a therapeutic for patients who have developed resistance to PAPRi or other chemotherapies. Addressing treatment for resistant tumors continues to be an unmet medical need in cancer treatment," said Dr. Tai-Sen Soong, CEO of Senhwa Biosciences.

About CX-5461

Specific mutations within the Homologous Recombination (HR) pathway may be exploited by CX-5461 through a synthetic lethality approach by targeting the DNA repair defects in Homologous Recombination Deficiency (HRD) tumors. Specifically, CX-5461 is designed to stabilize DNA G-quadruplexes of cancer cells which leads to disruption of the cell’s replication fork. While acting in concert with HR pathway deficiencies, such as BRCA1/2 mutations, replication forks stall and cause DNA breaks, ultimately resulting in cancer cell death.

IMBRUVICA® (ibrutinib) U.S. Prescribing Information Updated to Include Long-Term Data for Waldenström’s Macroglobulinemia (WM)

On December 23, 2020 AbbVie (NYSE: ABBV) reported that the U.S. Food and Drug Administration (FDA) approved the update of the IMBRUVICA (ibrutinib) Prescribing Information to include efficacy and safety data for the combination of IMBRUVICA with rituximab for the treatment of Waldenström’s macroglobulinemia (WM), based on the final analysis of the Phase 3 iNNOVATE study (Press release, AbbVie, DEC 23, 2020, View Source [SID1234573237]). First approved in 2013, IMBRUVICA is currently available to patients with several types of blood cancer, as well as chronic graft-versus-host disease. It was approved as a monotherapy for WM in 2015 and as a combination therapy with rituximab in 2018 based on the iNNOVATE primary analysis.

"We’re encouraged by this latest recognition from the FDA as it underscores our commitment to supporting those impacted by Waldenström’s macroglobulinemia, a rare and incurable form of non-Hodgkin’s lymphoma," said Danelle James, M.D., M.A.S., IMBRUVICA Global Development Lead, Pharmacyclics LLC, an AbbVie company. "IMBRUVICA is the only FDA-approved treatment for these patients and now includes more than five years of safety and efficacy data to help provide better understanding of how to treat this rare blood cancer."

As of today, IMBRUVICA is the only Bruton’s tyrosine kinase (BTK) inhibitor approved to treat WM. WM typically affects older adults and is primarily found in the bone marrow, although lymph nodes and the spleen may also be affected. In the U.S., there are approximately 2,800 new cases of WM each year.1 The National Comprehensive Cancer Network (NCCN), a not-for-profit alliance of 28 leading cancer centers devoted to patient care, research, and education, recommends IMBRUVICA, with or without rituximab, as the only Category 1 Preferred regimen for patients with previously untreated or previously treated WM.2

"The long-term results from the Phase 3 iNNOVATE study provide clinicians even more evidence that patients with WM can benefit from treatment with an ibrutinib-based regimen and maintain prolonged progression-free survival," said Dr. Meletios A. Dimopoulos, Professor and Chairman of the Department of Clinical Therapeutics, National and Kapodistrian University of Athens School of Medicine, Athens, Greece, and principal investigator.

The IMBRUVICA Prescribing Information now includes final analysis data, with an overall follow-up of 63 months, from the Phase 3 iNNOVATE clinical trial. With additional follow-up since the primary analysis, the combination of IMBRUVICA plus rituximab continued to demonstrate prolonged progression-free survival (PFS) in WM patients compared to rituximab monotherapy. Patients treated in the IMBRUVICA arm experienced a 75 percent reduction in risk of disease progression or death compared to rituximab monotherapy (hazard ratio [HR] 0.25; 95% confidence interval [CI]: 0.15-0.42; p<0.0001). Results from the final analysis of the study were recently featured as an oral presentation at the 2020 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (Abstract #336).

In the iNNOVATE study primary analysis, the most common side effects (≥20%) in patients treated with IMBRUVICA plus rituximab were bruising, muscle pain, bleeding problems, diarrhea, rash, joint pain, nausea and high blood pressure.

About iNNOVATE
iNNOVATE (PCYC-1127) is a Pharmacyclics-sponsored, randomized, placebo-controlled, double-blind, Phase 3 study, which enrolled 150 patients with relapsed/refractory and treatment-naïve Waldenström’s macroglobulinemia. All patients received intravenous rituximab 375 mg/m2 once weekly for four consecutive weeks, followed by a second four-weekly rituximab course following a three-month interval. Patients were randomized to receive either ibrutinib 420 mg or placebo once daily continuously until criteria for treatment discontinuation were met. The primary endpoint was progression-free survival; secondary endpoints included overall response rate; hematological improvement measured by hemoglobin; time-to-next treatment; overall survival; and number of participants with adverse events as a measure of safety and tolerability within each treatment arm.

About IMBRUVICA
IMBRUVICA is a once-daily, first-in-class BTK inhibitor that is administered orally, and is jointly developed and commercialized by Pharmacyclics, LLC, an AbbVie Company, and Janssen Biotech, Inc. (Janssen). The BTK protein sends important signals that tell B cells to mature and produce antibodies. BTK signaling is needed by specific cancer cells to multiply and spread.3,4 By blocking BTK, IMBRUVICA may help move abnormal B cells out of their nourishing environments in the lymph nodes, bone marrow, and other organs.5

Since its launch in 2013, IMBRUVICA has received 11 FDA approvals across six disease areas: chronic lymphocytic leukemia (CLL) with or without 17p deletion (del17p); small lymphocytic lymphoma (SLL) with or without del17p; WM; previously-treated patients with mantle cell lymphoma (MCL)*; previously-treated patients with marginal zone lymphoma (MZL) who require systemic therapy and have received at least one prior anti-CD20-based therapy* – and previously-treated patients with chronic graft-versus-host disease (cGVHD) after failure of one or more lines of systemic therapy.6

IMBRUVICA is now approved in 101 countries and has been used to treat more than 200,000 patients worldwide across its approved indications. IMBRUVICA is the only FDA-approved medicine in WM and cGVHD. IMBRUVICA has been granted four Breakthrough Therapy Designations from the U.S. FDA. This designation is intended to expedite the development and review of a potential new drug for serious or life-threatening diseases. IMBRUVICA was one of the first medicines to receive FDA approval via the Breakthrough Therapy Designation pathway.

As of early 2019, the National Comprehensive Cancer Network (NCCN), a not-for-profit alliance of 28 leading cancer centers devoted to patient care, research, and education, recommends ibrutinib (IMBRUVICA) as a preferred regimen for the initial treatment of CLL/SLL and is a Category 1 treatment for treatment-naïve patients without deletion 17p. In January 2020, the NCCN Guidelines were updated to recommend IMBRUVICA, with or without rituximab, as a preferred regimen for the treatment of relapsed/refractory MCL, regardless of response duration to prior chemoimmunotherapy. In September 2020, the NCCN guidelines for WM were updated and now recommends IMBRUVICA, with or without rituximab, as the only Category 1 Preferred regimen for patients with previously untreated or previously treated WM.

IMBRUVICA is being studied alone and in combination with other treatments in several blood and solid tumor cancers and other serious illnesses. IMBRUVICA is the most comprehensively studied BTK inhibitor, with more than 150 ongoing clinical trials. There are approximately 30 ongoing company-sponsored trials, 14 of which are in Phase 3, and more than 100 investigator-sponsored trials and external collaborations that are active around the world. For more information, visit www.IMBRUVICA.com.

*Accelerated approval was granted for the MCL and MZL indications based on overall response rate. Continued approval for MCL and MZL may be contingent upon verification and description of clinical benefit in confirmatory trials.

What are the possible side effects of IMBRUVICA?

IMBRUVICA may cause serious side effects, including:

Bleeding problems (hemorrhage) are common during treatment with IMBRUVICA, and can also be serious and may lead to death. Your risk of bleeding may increase if you are also taking a blood thinner medicine. Tell your healthcare provider if you have any signs of bleeding, including: blood in your stools or black stools (looks like tar), pink or brown urine, unexpected bleeding, or bleeding that is severe or that you cannot control, vomit blood or vomit looks like coffee grounds, cough up blood or blood clots, increased bruising, dizziness, weakness, confusion, change in your speech, or a headache that lasts a long time or severe headache.
Infections can happen during treatment with IMBRUVICA. These infections can be serious and may lead to death. Tell your healthcare provider right away if you have fever, chills, weakness, confusion, or other signs or symptoms of an infection during treatment with IMBRUVICA.
Decrease in blood cell counts. Decreased blood counts (white blood cells, platelets, and red blood cells) are common with IMBRUVICA, but can also be severe. Your healthcare provider should do monthly blood tests to check your blood counts.
Heart problems. Serious heart rhythm problems (ventricular arrhythmias, atrial fibrillation, and atrial flutter), heart failure, and death have happened in people treated with IMBRUVICA, especially in people who have an increased risk for heart disease, have an infection, or who have had heart rhythm problems in the past. Tell your healthcare provider if you get any symptoms of heart problems, such as feeling as if your heart is beating fast and irregular, lightheadedness, dizziness, shortness of breath, swelling of the feet, ankles, or legs, chest discomfort, or you faint. If you develop any of these symptoms, your healthcare provider may do a test to check your heart (ECG) and may change your IMBRUVICA dose.
