The safety and tolerability profile of niraparib was consistent with previous clinical trials.

Dr Hal Barron, Chief Scientific Officer and President, R&D, GSK, said: "Almost 300,000 women around the world are diagnosed with ovarian cancer every year, yet only about 15% of patients are currently eligible to receive PARP inhibitors as their initial therapy. These exciting data demonstrate that ZEJULA has the potential to significantly benefit even more women with this devastating cancer."

The full results from PRIMA will be presented at an upcoming scientific meeting.

Niraparib is marketed in the United States and Europe under the trade name ZEJULA.

About PRIMA

PRIMA is a double-blind, randomized Phase 3 study designed to evaluate niraparib versus placebo in first-line Stage III or IV ovarian cancer patients. The study assesses the efficacy of niraparib as maintenance treatment, as measured by progression free survival. Platinum responsive patients were randomized 2:1 to niraparib or placebo. The trial incorporated an individualized niraparib starting dose of 200 mg once-daily in patients with baseline weight <77kg or platelet count <150K/μL and 300 mg in all other patients.

About Ovarian Cancer

Approximately 22,000 women are diagnosed each year with ovarian cancer in the United States, and more than 65,000 women are diagnosed annually in Europe. Ovarian cancer is the fifth most frequent cause of cancer death among women. Despite high response rates to platinum-based chemotherapy in the second-line advanced treatment setting, approximately 85% of patients will experience recurrence within two years.

About niraparib

Niraparib is an oral, once-daily PARP inhibitor that is currently being evaluated in three pivotal trials. The ongoing development program for niraparib includes the Phase 3 PRIMA trial, a Phase 3 trial for the treatment of patients with germline BRCA-mutated, metastatic breast cancer (the BRAVO trial), and a registrational Phase 2 treatment trial in patients with ovarian cancer (the QUADRA trial). Several combination studies are also underway, including trials of niraparib plus pembrolizumab in metastatic, triple-negative breast cancer and advanced, platinum-resistant ovarian cancer (the TOPACIO trial) and niraparib plus bevacizumab in recurrent, platinum-sensitive ovarian cancer (the ENGOT-OV24/AVANOVA trial). Janssen Biotech has licensed rights to develop and commercialize niraparib specifically for patients with prostate cancer worldwide, except in Japan.

Important Safety Information for ZEJULA

Myelodysplastic Syndrome/Acute Myeloid Leukaemia (MDS/AML), including some fatal cases, was reported in 1.4% of patients receiving ZEJULA vs 1.1% of patients receiving placebo in Trial 1 (NOVA), and 0.9% of patients treated with ZEJULA in all clinical studies. The duration of ZEJULA treatment in patients prior to developing MDS/AML varied from <1 month to 2 years. All patients had received prior chemotherapy with platinum and some had also received other DNA damaging agents and radiotherapy. Discontinue ZEJULA if MDS/AML is confirmed.

Hematologic adverse reactions (thrombocytopenia, anaemia and neutropenia) have been reported in patients receiving ZEJULA. Grade ≥3 thrombocytopenia, anaemia and neutropenia were reported in 29%, 25%, and 20% of patients receiving ZEJULA, respectively. Discontinuation due to thrombocytopenia, anaemia, and neutropenia occurred, in 3%, 1%, and 2% of patients, respectively. Do not start ZEJULA until patients have recovered from haematological toxicity caused by prior chemotherapy (≤ Grade 1). Monitor complete blood counts weekly for the first month, monthly for the next 11 months of treatment, and periodically thereafter. If haematological toxicities do not resolve within 28 days following interruption, discontinue ZEJULA, and refer the patient to a haematologist for further investigations.

Hypertension and hypertensive crisis have been reported in patients receiving ZEJULA. Grade 3-4 hypertension occurred in 9% of patients receiving ZEJULA vs 2% of patients receiving placebo in Trial 1, with discontinuation occurring in <1% of patients. Monitor blood pressure and heart rate monthly for the first year and periodically thereafter during treatment with ZEJULA. Closely monitor patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension. Manage hypertension with antihypertensive medications and adjustment of the ZEJULA dose, if necessary.

Based on its mechanism of action, ZEJULA can cause foetal harm. Advise females of reproductive potential of the potential risk to a foetus and to use effective contraception during treatment and for 6 months after receiving their final dose. Because of the potential for serious adverse reactions from ZEJULA in breastfed infants, advise lactating women to not breastfeed during treatment with ZEJULA and for 1 month after receiving the final dose.

In clinical studies, the most common adverse reactions (Grades 1-4) in ≥10% of patients included: thrombocytopenia (61%), anaemia (50%), neutropenia (30%), leukopenia (17%), palpitations (10%), nausea (74%), constipation (40%), vomiting (34%), abdominal pain/distention (33%), mucositis/stomatitis (20%), diarrhoea (20%), dyspepsia (18%), dry mouth (10%), fatigue/asthenia (57%), decreased appetite (25%), urinary tract infection (13%), aspartate aminotransferase (AST)/alanine aminotransferase (ALT) elevation (10%), myalgia (19%), back pain (18%), arthralgia (13%), headache (26%), dizziness (18%), dysgeusia (10%), insomnia (27%), anxiety (11%), nasopharyngitis (23%), dyspnoea (20%), cough (16%), rash (21%) and hypertension (20%).

Common lab abnormalities (Grades 1-4) in ≥25% of patients included: decrease in haemoglobin (85%), decrease in platelet count (72%), decrease in white blood cell count (66%), decrease in absolute neutrophil count (53%), increase in AST (36%) and increase in ALT (28%).

Ascentage Pharma announces first patient dosed in Phase I clinical trial of APG-2575 in China as the first China-made Bcl-2 Inhibitor

On July 14, 2019 Ascentage Pharma, a globally-focused, clinical-stage biotechnology company engaged in developing novel therapies for cancers, hepatitis B virus and age-related diseases, reported that the company recently dosed the first patient successfully in a Phase I clinical trial of APG-2575, a novel Bcl-2 selective inhibitor, for the treatment of hematologic malignancies in China (Press release, , JUL 14, 2019, View Source [SID1234537515]). The Company also has an ongoing multi-center Phase I dose-escalation study of APG-2575 as a single agent in the United States and Australia. APG-2575 could potentially be the first China-made Bcl-2 inhibitor.

APG-2575 is a novel, orally administered Bcl-2 selective inhibitor. It is designed to treat hematologic malignancies by selective blocking Bcl-2 to restore the normal apoptosis process in cancer cells.

Bcl-2 is the founding member of the Bcl-2 family proteins which are most notable for their critical roles in the regulation of apoptosis through the formation of heterodimers with pro-apoptotic proteins (BIM, BAD and most others). Due to the very large and hydrophobic interfaces of Bcl-2 proteins, it is difficult to develop a drug that targets Bcl-2 family protein. The marketed Bcl-2 inhibitor venetoclax/ABT-199 approved by the U.S. FDA in April 2016 has validated the clinical basis for further targeted drug development. Ascentage Pharma’s APG-2575 is one of the few Bcl-2 selective inhibitors in active clinical trials other than Venetoclax.

This Phase I trial is designed to assess the safety and tolerance of APG-2575 in patients with hematologic malignancies and confirm the maximal tolerated dose (MTD) or recommended Phase II dose (RP2D) of APG-2575. Included in this trial are patients with acute myelogenous leukemia (AML), non-Hodgkin’s lymphoma (NHL). Currently, the first patient enrolled in China has been dosed at Institute of Hematology, Blood Disease Hospital of Chinese Academy of Medical Sciences during the first stage of dose-escalation.

The Phase I dose-escalation clinical trial of APG-2575 in the United States and Australia is being conducted at several academic institutions including MD Anderson Cancer Center and Mayo Clinic. Included in this trial are patients with various types of blood cancer, such as CLL, NHL, MM, AML. At present, 4 dose cohorts have been completed in the United States and Australia. Preliminary data suggested that APG-2575 was well tolerated and safe, it had promising anti-tumor activity in the treatment of relapsed/refractory CLL.

During the 2019 American Association for Cancer Research (AACR) (Free AACR Whitepaper) annual meeting, Ascentage Pharma released several preclinical research results of APG-2575, which demonstrated the potential in combination therapy.

"APG-2575 is a key product in our development pipeline of apoptosis. Initiating the clinical trial in China represents a new step in our global clinical development. We believe that APG-2575 may provide more therapy options to patients with blood diseases," said Dr. Dajun Yang, Chairman and CEO of Ascentage Pharma.

About APG-2575
APG-2575 is a novel, orally administered Bcl-2 selective inhibitor developed by Ascentage Pharma. It is designed to treat hematologic malignancies by selective blocking Bcl-2 to restore the normal apoptosis process in cancer cells.

The Company recently initiated a phase I clinical trial of APG-2575 in China, which is the first domestic Bcl-2 selective inhibitor entered the clinical stage. Ascentage previously has initiated a multi-center Phase I dose-escalation study of APG-2575 as a single agent in multiple hematologic malignancies in the United States and Australia in August 2018.

The submission is supported by data from the Phase 3 COLUMBA (MMY3012) study first presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting that included a non-inferiority comparison to DARZALEX IV administration for co-primary endpoints of overall response rate and maximum Ctrough concentration. Data from the Phase 2 PLEIADES (MMY2040) study are also included in the BLA. The subcutaneous formulation of DARZALEX is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20) [Halozyme’s ENHANZE drug delivery technology].

"This submission represents our commitment to develop innovative treatment options for people living with multiple myeloma," said Craig Tendler, M.D., Vice President, Clinical Development and Global Medical Affairs, Oncology, Janssen Research & Development, LLC. "The DARZALEX subcutaneous formulation showed non-inferiority to the existing IV formulation, both as a monotherapy and in combination with common background therapies, while administered with a considerably shorter infusion time. We look forward to working closely with the FDA in their review of the data supporting this regulatory application."

Today’s submission follows two recent milestones for the DARZALEX intravenous formulation, including an approval of DARZALEX in combination with lenalidomide and dexamethasone for the treatment of newly diagnosed, transplant ineligible patients with multiple myeloma supported by the Phase 3 MAIA study, and Priority Review designation following submission of a supplemental BLA based on the Phase 3 CASSIOPEIA study, which is seeking approval of DARZALEX in combination with bortezomib, thalidomide and dexamethasone for newly diagnosed patients with multiple myeloma who are transplant eligible.

About the COLUMBA Study (MMY3012)1
The randomized, open-label, multicenter Phase 3 COLUMBA study included 522 patients with multiple myeloma who had received at least three prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory drug (IMiD), or whose disease was refractory to both a PI and an IMiD (median age of 67). In the arm that received the SC formulation of DARZALEX (n=263), patients received a fixed dose of DARZALEX 1,800 milligrams (mg), co-formulated with recombinant human hyaluronidase PH20 (rHuPH20) 2,000 Units per milliliter (U/mL), subcutaneously weekly for Cycles 1 – 2, every two weeks for Cycles 3 – 6 and every four weeks for Cycle 7 and thereafter. In the DARZALEX IV arm (n=259), patients received DARZALEX for IV infusion 16 milligrams per kilogram (mg/kg) weekly for Cycles 1 – 2, every two weeks for Cycles 3 – 6 and every four weeks for Cycle 7 and thereafter. Each cycle was 28 days. In the arm that received the SC formulation, DARZALEX was given as a fixed volume over 3 – 5 minutes. In the arm that received the IV administration, the median durations of the first, second and subsequent DARZALEX IV infusions were 7.0, 4.3 and 3.4 hours, respectively. Patients in both treatment arms continued until disease progression or unacceptable toxicity.

About the PLEIADES Study (MMY2040)2
The non-randomized, open-label, parallel assignment Phase 2 PLEIADES study included 240 adults either newly diagnosed or with relapsed or refractory multiple myeloma. Patients with newly diagnosed multiple myeloma were treated with 1,800 mg of the SC formulation in combination with either bortezomib, lenalidomide and dexamethasone (D-VRd) or bortezomib, melphalan, and prednisone (D-VMP). Patients with relapsed or refractory disease were treated with 1,800 mg of the SC formulation plus lenalidomide and dexamethasone (D-Rd). The primary endpoint for the D-VMP and D-Rd cohorts was overall response rate. The primary endpoint for the D-VRd cohort was very good partial response or better rate. An additional cohort of patients with relapsed and refractory multiple myeloma treated with daratumumab plus carfilzomib and dexamethasone was subsequently added to the study.

About DARZALEX (daratumumab)
DARZALEX (daratumumab), the first CD38-directed antibody approved anywhere in the world, is the only CD38-directed antibody approved to treat multiple myeloma.3 CD38 is a surface protein that is present in high numbers on multiple myeloma cells, regardless of the stage of disease.4 DARZALEX binds to CD38 and inhibits tumor cell growth causing myeloma cell death.3 DARZALEX may also have an effect on normal cells.3 DARZALEX is being evaluated in a comprehensive clinical development program across a range of treatment settings in multiple myeloma, such as in frontline and relapsed settings.5,6,7,8,9,10,11,12 Additional studies are ongoing or planned to assess its potential in other malignant and pre-malignant hematologic diseases in which CD38 is expressed, such as smoldering myeloma.13,14

In the United States, DARZALEX received initial FDA approval in November 2015 as a monotherapy for patients with multiple myeloma who have received at least three prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent, or who are double refractory to a PI and an immunomodulatory agent.15 DARZALEX received additional approvals in November 2016 in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of patients with multiple myeloma who have received at least one prior therapy.16 In June 2017, DARZALEX received approval in combination with pomalidomide and dexamethasone for the treatment of patients with multiple myeloma who have received at least two prior therapies, including lenalidomide and a PI.17 In May 2018, DARZALEX received approval in combination with bortezomib, melphalan and prednisone for the treatment of patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant (ASCT), making it the first monoclonal antibody approved for newly diagnosed patients with this disease.18 Most recently, in June 2019, DARZALEX was approved in combination with lenalidomide and dexamethasone for the treatment of patients with newly diagnosed multiple myeloma who are ineligible for ASCT.19 More than 80,000 patients have been treated with DARZALEX worldwide.

In August 2012, Janssen Biotech, Inc. entered into a global license and development agreement with Genmab A/S, which granted Janssen an exclusive license to develop, manufacture and commercialize DARZALEX.20 For the full U.S. Prescribing Information, please visit www.DARZALEX.com.

About Multiple Myeloma
Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.21,22 When damaged, these plasma cells rapidly spread and replace normal cells with tumors in the bone marrow.22,23 In 2019, it is estimated that more than 32,000 people will be diagnosed, and nearly 13,000 will die from the disease in the United States.23 While some patients with multiple myeloma have no symptoms, most patients are diagnosed due to symptoms, which can include bone fracture or pain, low red blood counts, tiredness, high calcium levels, kidney problems or infections.24

IMPORTANT SAFETY INFORMATION3

CONTRAINDICATIONS
DARZALEX (daratumumab) is contraindicated in patients with a history of severe hypersensitivity (eg, anaphylactic reactions) to daratumumab or any of the components of the formulation.

WARNINGS AND PRECAUTIONS
Infusion Reactions – DARZALEX can cause severe and/or serious infusion reactions, including anaphylactic reactions. In clinical trials, approximately half of all patients experienced an infusion reaction. Most infusion reactions occurred during the first infusion and were Grade 1-2. Infusion reactions can also occur with subsequent infusions. Nearly all reactions occurred during infusion or within 4 hours of completing DARZALEX. Prior to the introduction of post-infusion medication in clinical trials, infusion reactions occurred up to 48 hours after infusion. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, laryngeal edema, and pulmonary edema. Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting, and nausea. Less common symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, and hypotension.

Pre-medicate patients with antihistamines, antipyretics, and corticosteroids. Frequently monitor patients during the entire infusion. Interrupt infusion for reactions of any severity and institute medical management as needed. Permanently discontinue therapy if an anaphylactic reaction or life-threatening (Grade 4) reaction occurs and institute appropriate emergency care. For patients with Grade 1, 2, or 3 reactions, reduce the infusion rate when re-starting the infusion.

To reduce the risk of delayed infusion reactions, administer oral corticosteroids to all patients following DARZALEX infusions. Patients with a history of chronic obstructive pulmonary disease may require additional post-infusion medications to manage respiratory complications. Consider prescribing short- and long-acting bronchodilators and inhaled corticosteroids for patients with chronic obstructive pulmonary disease.

Interference With Serological Testing – Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive Indirect Antiglobulin Test (Indirect Coombs test). Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6 months after the last daratumumab infusion. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient’s serum. The determination of a patient’s ABO and Rh blood type are not impacted. Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX. Type and screen patients prior to starting DARZALEX.

Neutropenia and Thrombocytopenia – DARZALEX may increase neutropenia and/or thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to the manufacturer’s prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. DARZALEX dose delay may be required to allow recovery of neutrophils and/or platelets. No dose reduction of DARZALEX is recommended. Consider supportive care with growth factors for neutropenia or transfusions for thrombocytopenia.

Interference With Determination of Complete Response – Daratumumab is a human IgG kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.
