Merck Announces Phase 3 Study of Single-Dose EMEND® (fosaprepitant dimeglumine) for Injection Regimen Met Primary Endpoint in Prevention of Chemotherapy-Induced Nausea and Vomiting in Patients Receiving Moderately Emetogenic Chemotherapy

On June 29, 2015 Merck reported results from a Phase 3 study investigating the safety and efficacy of single-dose EMEND (fosaprepitant dimeglumine) for Injection, Merck’s substance P/neurokinin (NK-1) receptor antagonist, in combination with other anti-vomiting medicines, for the prevention of chemotherapy-induced nausea and vomiting (CINV) in adult cancer patients receiving moderately emetogenic (vomit-inducing) chemotherapy (MEC) (Press release, Merck & Co, JUN 29, 2015, View Source [SID:1234506001]). In the study, the first to evaluate an intravenous NK-1 receptor antagonist for the prevention of CINV associated with MEC, the single-dose EMEND for Injection regimen provided greater protection from nausea and vomiting following administration of chemotherapy versus an active control of placebo with other anti-vomiting medicines. These data were presented in an oral session at the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) Annual Meeting on Supportive Care in Cancer (Abstract #27-02-O) in Copenhagen (June 25-27, 2015).

"The results from this important Phase 3 trial are very encouraging as they are the first study to evaluate EMEND for Injection in a combination regimen for the prevention of chemotherapy-induced nausea and vomiting in patients receiving moderately emetogenic chemotherapy – and show the potential to use a single day antiemetic regimen," said Dr. Bernardo L. Rapoport, principal investigator for the study and chief medical oncologist, Medical Oncology Centre of Rosebank, Johannesburg, South Africa.

"Nausea and vomiting remain a significant burden for patients receiving chemotherapy and we look forward to submitting these data for EMEND for Injection to the U.S. Food and Drug Administration," said Stuart Green, vice president, clinical research, Merck Research Laboratories. "This study builds on our decade of research for EMEND and Merck’s overall commitment to help people with cancer."

EMEND for Injection, a substance P/Neurokinin-1 (NK1) receptor antagonist approved for use in combination with other antiemetic agents, is indicated in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer (HEC) chemotherapy, including high-dose cisplatin; and for prevention of nausea and vomiting associated with initial and repeat courses of MEC. EMEND has not been studied for treatment of established nausea and vomiting. Chronic continuous administration of EMEND is not recommended.

In the U.S., the single-dose regimen of EMEND for Injection is approved for use associated with HEC. Merck plans to submit these recent data to the Food and Drug Administration in the second half of 2015 to seek approval for a regimen containing single-dose EMEND for Injection for the prevention of CINV associated with MEC.

About Phase 3 Study for Single-Dose EMEND for Injection in MEC

In this global randomized, Phase 3, double-blind study, more than 1,000 patients receiving MEC were randomly assigned to receive either single-dose EMEND for Injection (150 mg) in combination with ondansetron capsules (16 mg) and dexamethasone capsules (12 mg) (n=504) on day one (followed by oral placebo for ondansetron on days two and three) or an active control regimen consisting of placebo (saline IV) in combination with ondansetron (16 mg) and dexamethasone (20 mg) (n=497) on day one (followed by 8 mg ondansetron on days two and three). The primary endpoint of the study was complete response (CR) (as measured by no vomiting and no use of rescue medication for nausea or vomiting) in the delayed phase (25 to 120 hours following initiation of chemotherapy). The secondary endpoints were CR after the first dose of chemotherapy in the acute phase (0 to 24 hours) and in the overall phase (0-120 hours), as well as no vomiting in the overall phase.

Single-Dose EMEND for Injection Regimen Achieved Superior Control of CINV

For the primary study endpoint, EMEND for Injection regimen provided higher incidence of CR in days 2 through 5 – with CR observed in 78.9 percent of patients receiving the EMEND for Injection regimen versus 68.5 percent in the active control group (p <0.001). For the secondary endpoints, in the acute phase, CR was observed in 93.2 percent of patients receiving the EMEND for Injection regimen versus 91 percent in the active control group (p = 0.184). In the overall phase, the incidence of CR was observed in 77.1 percent of patients receiving the EMEND for Injection regimen versus 66.9 percent in the active control group (p <0.001). Additionally, a significantly greater proportion of patients receiving the EMEND for Injection regimen experienced no vomiting in the overall phase (82.7 percent with EMEND vs 72.9 percent in the active control group) and delayed phase (83.9 percent with EMEND vs 75.1 percent in the active control group) (both p <0.001) – with a favorable trend in the acute phase (94.8 percent with EMEND vs 92 percent in the active control group).

The most common adverse events (across all grades) in the EMEND for Injection regimen and active control group included fatigue (15.1 percent and 12.9 percent), diarrhea (12.7 percent and 11.3 percent), and constipation (9.3 percent and 10.5 percent). Treatment-related adverse events were observed in 8.5 percent of patients receiving the EMEND for Injection regimen and in 9.1 percent of patients in the active control group. Serious treatment-related adverse events were observed in 0.2 percent of patients receiving the EMEND for Injection regimen and in 0.4 percent of patients in the active control group.

Selected Important Safety Information for EMEND (fosaprepitant dimeglumine) For Injection

EMEND for Injection is contraindicated in patients who are hypersensitive to EMEND for Injection, aprepitant, polysorbate 80, or any other components of the product. Known hypersensitivity reactions include flushing, erythema, dyspnea, and anaphylactic reactions.

Aprepitant, when administered orally, is a moderate cytochrome P450 isoenzyme 3A4 (CYP3A4) inhibitor. Because fosaprepitant is rapidly converted to aprepitant, neither drug should be used concurrently with pimozide or cisapride. Inhibition of CYP3A4 by aprepitant could result in elevated plasma concentrations of these drugs, potentially causing serious or life-threatening reactions.

EMEND for Injection should be used with caution in patients receiving concomitant medications, including chemotherapy agents that are primarily metabolized through CYP3A4. Inhibition of CYP3A4 by EMEND for Injection could result in elevated plasma concentrations of these concomitant medications. Conversely, when EMEND for Injection is used concomitantly with another CYP3A4 inhibitor, aprepitant plasma concentrations could be elevated. When EMEND for Injection is used concomitantly with medications that induce CYP3A4 activity, aprepitant plasma concentrations could be reduced, and this may result in decreased efficacy of aprepitant.

Chemotherapy agents that are known to be metabolized by CYP3A4 include docetaxel, paclitaxel, etoposide, irinotecan, ifosfamide, imatinib, vinorelbine, vinblastine, and vincristine. In clinical studies, EMEND was administered commonly with etoposide, vinorelbine, or paclitaxel. The doses of these agents were not adjusted to account for potential drug interactions. In separate pharmacokinetic studies, EMEND did not influence the pharmacokinetics of docetaxel or vinorelbine.

Because a small number of patients in clinical studies received the CYP3A4 substrates vinblastine, vincristine, or ifosfamide, particular caution and careful monitoring are advised in patients receiving these agents or other chemotherapy agents metabolized primarily by CYP3A4 that were not studied.

There have been isolated reports of immediate hypersensitivity reactions, including flushing, erythema, dyspnea, and anaphylaxis, during infusion of fosaprepitant. These hypersensitivity reactions have generally responded to discontinuation of the infusion and administration of appropriate therapy. It is not recommended to reinitiate the infusion in patients who have experienced these symptoms during first-time use.

Coadministration of EMEND for Injection with warfarin (a CYP2C9 substrate) may result in a clinically significant decrease in international normalized ratio (INR) of prothrombin time. In patients on chronic warfarin therapy, the INR should be closely monitored in the 2-week period, particularly at 7 to 10 days, following initiation of EMEND for Injection with each chemotherapy cycle.

The efficacy of hormonal contraceptives (including birth control pills, skin patches, implants, and certain IUDs) may be reduced during coadministration with and for 28 days after the last dose of EMEND for Injection. Alternative or backup methods of contraception should be used during treatment with and for 1 month after the last dose of EMEND for Injection.

Chronic continuous use of EMEND for Injection for prevention of nausea and vomiting is not recommended because it has not been studied and because the drug interaction profile may change during chronic continuous use.

In clinical trials of EMEND in patients receiving HEC, the most common adverse events reported at a frequency greater than with standard therapy, and at an incidence of 1% or greater, were hiccups (4.6% EMEND vs 2.9% standard therapy), asthenia/fatigue (2.9% vs 1.6%), increased ALT (2.8% vs 1.5%), increased AST (1.1% vs 0.9%), constipation (2.2% vs 2.0%), dyspepsia (1.5% vs 0.7%), diarrhea (1.1% vs 0.9%), headache (2.2% vs 1.8%), and anorexia (2.0% vs 0.5%).

In a clinical trial evaluating safety of the 1-day regimen of EMEND for Injection compared with the 3-day regimen of EMEND, the safety profile was generally similar to that seen in prior HEC studies with aprepitant. However, infusion-site reactions occurred at a higher incidence in patients who received fosaprepitant (3.0%) than in those who received aprepitant (0.5%). Those infusion-site reactions included infusion-site erythema, infusion-site pruritus, infusion-site pain, infusion-site induration, and infusion-site thrombophlebitis.

About Chemotherapy Induced Nausea and Vomiting (CINV)

Chemotherapy Induced Nausea and Vomiting (CINV) is a common side effect of chemotherapy caused by injured stomach cells that start the process of nausea and vomiting and can directly activate the area of the brain responsible for producing nausea and vomiting. The two main types of CINV are acute and delayed. Acute happens within the first 24 hours of receiving chemotherapy. Delayed happens from day 2 to day 5 after chemotherapy. The amount and timing of CINV can vary. Some chemotherapies cause acute nausea and vomiting. Others cause acute nausea and vomiting followed by another period of delayed nausea and vomiting.

RedHill Biopharma Initiates Phase I/II Study of ABC294640 for Refractory Lymphoma

On June 29, 2015 RedHill Biopharma reported that it has initiated a Phase I/II clinical study in the U.S. evaluating ABC294640 in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL) (Press release, RedHill Biopharma, JUN 29, 2015, View Source [SID:1234506006]).

ABC294640 is a proprietary, first-in-class, orally-administered sphingosine kinase-2 (SK2) selective inhibitor, with anti-inflammatory and anti-cancer activities, targeting multiple inflammatory, gastrointestinal (GI) and oncology indications. SK2 is an innovative molecular target for anti-cancer therapy because of its critical role in catalyzing the formation of the lipid-signaling molecule sphingosine 1-phosphate (S1P), which is known to regulate cell proliferation and activation of inflammatory pathways. By inhibiting SK2, ABC294640 could potentially be effective in treating multiple inflammatory, oncologic and gastrointestinal diseases.

The Phase I/II study is intended to evaluate the safety and tolerability of ABC294640, as well as provide a preliminary evaluation of efficacy of the drug in patients with refractory/relapsed DLBCL, primarily patients with HIV-related DLBCL. Up to 33 patients are expected to be enrolled in the study, which will be conducted at the Louisiana State University Health Sciences Center (LSUHSC) in New Orleans. The study is funded primarily by a grant awarded by the National Cancer Institute (NCI) Small Business Technology Transfer (STTR) program. Dr. Chris Parsons, MD, an associate professor in the Departments of Medicine and Microbiology, Immunology & Parasitology at LSUHSC, is the lead investigator for the study.

Dr. Terry Plasse, MD, RedHill’s Medical Director, said: "We are excited to initiate this translational study with ABC294640, carrying Dr. Parson’s laboratory evaluations into an important clinical population of patients with refractory/relapsed diffuse large B-cell lymphoma, primarily patients with HIV-related DLBCL, a group of patients with substantial unmet medical needs. RedHill continues to advance towards additional Phase II clinical studies with ABC294640 as a radioprotectant in cancer patients undergoing therapeutic radiotherapy and, subject to a pending NCI/SBIR grant, multiple myeloma."

DLBCL is the most common subtype of non-Hodgkin’s lymphoma, accounting for an estimated 30% of the 70,000 projected non-Hodgkin’s lymphoma cases diagnosed in the U.S. in 20151. Many DLBCLs are etiologically linked to the human viruses which encode unique oncogenes contributing to tumor onset and progression. Standard treatments for DLBCL exhibit limited efficacy and incur significant toxicities.

The Phase I/II study was initiated following positive pre-clinical studies, led by Dr. Parsons, indicating the therapeutic activity of ABC294640 for virus-associated DLBCL, in an established xenograft model for Kaposi’s sarcoma-associated herpesvirus-associated DLBCL, including reversal of disease progression for established tumors. The pre-clinical studies were performed in parallel with a successful Phase I study that demonstrated the drug’s safety and assessed its pharmacokinetics and pharmacodynamics in cancer patients with advanced solid tumors.

RedHill acquired the rights to ABC294640 in March 2015 from U.S.-based Apogee Biotechnology Corporation ("Apogee"). Prior to the acquisition, Apogee completed numerous successful pre-clinical studies with ABC294640 in GI, inflammation, radioprotection and oncology models, as well as a successful Phase I clinical study in cancer patients with advanced solid tumors. The open-label, dose-escalation, Phase I clinical study demonstrated the drug’s safety and assessed its pharmacokinetics and pharmacodynamics in cancer patients with advanced solid tumors. The development of ABC294640 was funded to date primarily through grants and contracts in excess of $14 million from U.S. federal and state government agencies, such as the FDA, Department of Defense (DoD) and the National Institutes of Health (NIH), including the National Cancer Institute and BARDA.

A second Phase II study of ABC294640 is planned to evaluate ABC294640 as a radioprotectant to prevent mucositis in cancer patients undergoing therapeutic radiotherapy. RedHill also plans a third Phase II clinical study for the treatment of multiple myeloma, subject to funding by a pending grant from the National Cancer Institute.

The Phase I/II study with ABC294640 for refractory/relapsed diffuse large B-cell lymphoma is registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health which provides public access to information on publicly and privately supported clinical studies: View Source

About ABC294640:

ABC294640 is a first-in-class, proprietary sphingosine kinase-2 (SK2) selective inhibitor, administered orally, with anti-cancer and anti-inflammatory activities, targeting multiple potential inflammatory, oncology and gastrointestinal indications. By inhibiting the SK2 enzyme, ABC294640 blocks the synthesis of sphingosine 1-phosphate (S1P), a lipid that promotes cancer growth and pathological inflammation. ABC294640 was originally developed by U.S.-based Apogee Biotechnology Corp. and completed multiple successful pre-clinical studies in inflammatory, GI, radioprotection and oncology models, as well as a Phase I clinical study in cancer patients with advanced solid tumors. A Phase I/II clinical study evaluating ABC294640 in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL) has been initiated in the U.S. The development of ABC294640 was funded to date primarily through grants and contracts in excess of $14 million from U.S. federal and state government agencies.

Juno Announces FDA Acceptance of Investigational New Drug Application for JCAR017 in Relapsed/Refractory B Cell Non-Hodgkin Lymphoma

On June 29, 2015 Juno reported the U.S. Food and Drug Administration (FDA) accepted the Company’s investigational new drug (IND) application for JCAR017 for patients with relapsed/refractory (r/r) B cell non-Hodgkin lymphoma, or NHL (Press release, Juno, JUN 29, 2015, View Source [SID:1234506005]). JCAR017 is a chimeric antigen receptor (CAR) T cell product candidate targeting CD19, a protein expressed on the surface of most B cell leukemias and lymphomas.

The IND enables Juno to initiate a multi-center Phase I trial exploring JCAR017 for r/r NHL, scheduled to begin in 2015, with the potential to advance to a registration trial in 2016.

"Based on the encouraging results of JCAR017 in pediatric acute lymphoblastic leukemia, we are excited to begin investigating this product candidate in non-Hodgkin lymphoma," said Mark Frohlich, M.D., Juno EVP of development and portfolio strategy. "FDA acceptance of the JCAR017 IND for this multi-institutional study is an important milestone for Juno. Together with our planned fully-human CD19 CAR-T cell trial, combination study with AstraZeneca’s anti-PDL-1 antibody, and ongoing translational clinical trial with JCAR014, it will provide important biologic insights that will inform our future strategies."

In collaboration with Seattle Children’s Research Institute, Juno continues to investigate JCAR017 in pediatric patients with r/r acute lymphoblastic leukemia (ALL). Results of a Phase I study to date demonstrated 91 percent of patients achieved a complete remission, all of which were documented by flow cytometry. Adverse events were consistent with what has been previously reported. The results were presented in an oral presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2015 in Philadelphia.

About Juno’s Chimeric Antigen Receptor (CAR) and T Cell Receptor (TCR) Technologies
Juno’s chimeric antigen receptor (CAR) and T cell receptor technologies (TCR) genetically engineer T cells to recognize and kill cancer cells. Juno’s CAR T cell technology inserts a gene for a particular CAR into the T cell, enabling it to recognize cancer cells based on the expression of a specific protein located on the cell surface. Juno’s TCR technology provides the T cells with a specific T cell receptor to recognize protein fragments derived from either the surface or inside the cell. When either type of engineered T cell engages the target protein on the cancer cell, it initiates a cell-killing response against the cancer cell.
