On April 3, 2019 Tetraphase Pharmaceuticals, Inc. (NASDAQ:TTPH), a biopharmaceutical company focused on developing and commercializing novel tetracyclines to treat serious and life-threatening conditions, reported data from its preclinical program for TP-2846, the Company’s new pipeline candidate for acute myeloid leukemia (AML) discovered using Tetraphase’s proprietary total synthesis platform (Press release, Tetraphase, APR 3, 2019, View Source [SID1234534963]). The data were presented at the 2019 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, held March 29-April 3 at the Georgia World Congress Center in Atlanta. The posters showed results from preclinical in vitro and in vivo studies demonstrating the activity, potency and unique mechanism of action (MOA) of TP-2846.

"Preclinical testing has characterized TP-2846 as a novel, potent, synthetic tetracycline with activity across multiple in vitro and in vivo cancer models," said Guy Macdonald, President and Chief Executive Officer of Tetraphase. "We are very encouraged by these early data, which suggest that TP-2846 holds the potential to benefit AML patients regardless of their mutation status. Further, these data show that because of its unique MOA, TP-2846 may have antileukemic activity in patients whose cancer has progressed while on different treatment regimens."

"TP-2846 has a new MOA that has never before been fully explored clinically as a viable approach to treating AML," said Jacques Dumas, Chief Scientific Officer of Tetraphase. "Our preclinical data demonstrated high potency across multiple AML cell lines, along with in vivo tumor responses at well-tolerated doses. These early data are very encouraging and support the continued preclinical evaluation of TP-2846 as a potential new antileukemia agent."

TP-2846 binds to the mitochondrial ribosome, inhibiting protein translation and inducing apoptosis. Mechanistic assays demonstrated changes in protein and gene expression – all consistent with disruption of mitochondrial translation.

TP-2846 showed antiproliferative activity against cultured AML cell lines in vitro, as well as bone marrow samples derived from AML patients in ex vivo assays. The data available to date also suggest that TP-2846’s activity is independent of p53 status. Because of its novel MOA, TP-2846 maintained antiproliferative activity in cell lines that are resistant to anthracyclines, cytarabine and venetoclax, which are currently approved treatments for AML.

In vivo efficacy studies were also performed, comparing TP-2846 to cytarabine and tigecycline, a tetracycline antibacterial, in two AML mouse xenograft models. In these studies, TP-2846 demonstrated potent, dose-dependent in vivo efficacy, including greater than 50 percent tumor shrinkage in 19 out of 20 animals treated with TP-2846, while none in the comparator treatment groups achieved a tumor response in the same studies. TP-2846 was well tolerated in both models.

On April 3, 2019 Genmab A/S (Nasdaq Copenhagen: GEN) reported that its collaboration partner, Janssen Biotech, Inc. ("Janssen") plans to start a new Phase III study of daratumumab in multiple myeloma (Press release, Genmab, APR 3, 2019, View Source [SID1234534961]). The study (MMY3021) will compare subcutaneous daratumumab in combination with lenalidomide versus lenalidomide alone as maintenance treatment in patients with newly diagnosed multiple myeloma who are minimal residual disease (MRD) positive after frontline autologous stem cell transplant (ASCT). The primary end point of the study is MRD conversion rate, from MRD positive to MRD negative status, at twelve months. The study is planned to start in the first half of 2019. In August 2012, Genmab granted Janssen an exclusive worldwide license to develop, manufacture and commercialize daratumumab.

"We are pleased to see Janssen’s continual commitment to evaluating the use of daratumumab in a wide array of settings and combinations. We are hopeful that the study will provide evidence of daratumumab’s potential to provide a benefit to patients with multiple myeloma beyond current standard of care treatments in the maintenance phase of treatment," said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

About the MMY3021 study
The Phase III study is a randomized, open-label, multicenter study that will include up to 214 newly diagnosed patients with multiple myeloma who are MRD positive after autologous stem cell transplant and who have no prior anti-CD38 exposure. Patients will be randomized to receive either subcutaneous daratumumab in combination with lenalidomide or lenalidomide alone. In the daratumumab treatment arm, patients received 1,800 mg of subcutaneous daratumumab weekly for Cycles 1-2, every two weeks for Cycles 3-6 and every four weeks thereafter. Lenalidomide will be administered at 10 mg orally on days 1-28 with 15 mg given daily if it is well tolerated after three cycles. Both arms will continue until disease progression or for 36 cycles. The primary endpoint of the study is MRD-conversion at 12 months.

About multiple myeloma
Multiple myeloma is an incurable blood cancer that starts in the bone marrow and is characterized by an excess proliferation of plasma cells.1 Multiple myeloma is the third most common blood cancer in the U.S., after leukemia and lymphoma.2 Approximately 26,000 new patients were expected to be diagnosed with multiple myeloma and approximately 13,650 people were expected to die from the disease in the U.S. in 2018.3 Globally, it was estimated that 160,000 people were diagnosed and 106,000 died from the disease in 2018.4 While some patients with multiple myeloma have no symptoms at all, most patients are diagnosed due to symptoms which can include bone problems, low blood counts, calcium elevation, kidney problems or infections.5

About DARZALEX (daratumumab)
DARZALEX (daratumumab) injection for intravenous infusion is indicated in the United States 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; 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; 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 proteasome inhibitor (PI); and as a monotherapy for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy, including a PI and an immunomodulatory agent, or who are double-refractory to a PI and an immunomodulatory agent.6 DARZALEX is the first monoclonal antibody (mAb) to receive U.S. Food and Drug Administration (U.S. FDA) approval to treat multiple myeloma. DARZALEX is indicated in Europe in combination with bortezomib, melphalan and prednisone for the treatment of adult patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant; for use in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of adult patients with multiple myeloma who have received at least one prior therapy; and as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma, whose prior therapy included a PI and an immunomodulatory agent and who have demonstrated disease progression on the last therapy. The option to split the first infusion of DARZALEX over two consecutive days has been approved in both Europe and the U.S. In Japan, DARZALEX is approved in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of adults with relapsed or refractory multiple myeloma. DARZALEX is the first human CD38 monoclonal antibody to reach the market in the United Stated, Europe and Japan. For more information, visit www.DARZALEX.com.

Daratumumab is a human IgG1k monoclonal antibody (mAb) that binds with high affinity to the CD38 molecule, which is highly expressed on the surface of multiple myeloma cells. Daratumumab triggers a person’s own immune system to attack the cancer cells, resulting in rapid tumor cell death through multiple immune-mediated mechanisms of action and through immunomodulatory effects, in addition to direct tumor cell death, via apoptosis (programmed cell death).6,7,8,9,10

Daratumumab is being developed by Janssen Biotech, Inc. under an exclusive worldwide license to develop, manufacture and commercialize daratumumab from Genmab. A comprehensive clinical development program for daratumumab is ongoing, including multiple Phase III studies in smoldering, relapsed and frontline multiple myeloma settings and in amyloidosis. Additional studies are ongoing or planned to assess the potential of daratumumab in other malignant and pre-malignant diseases, such as NKT-cell lymphoma, B and T-ALL. Daratumumab has received two Breakthrough Therapy Designations from the U.S. FDA, for multiple myeloma, as both a monotherapy and in combination with other therapies.

The pivotal study IMCgp100-202 is a 2:1 randomized study of tebentafusp compared with Investigator’s Choice (dacarbazine, ipilimumab or pembrolizumab) in HLA-A*0201 positive adult patients with previously untreated mUM. The primary endpoint is a comparison of overall survival.

"For patients with metastatic uveal melanoma, the prognosis is poor and has not meaningfully changed in decades. Our goal is to test whether tebentafusp can prolong survival for these patients." comments David Berman, Head of R&D of Immunocore. "We are delighted that tebentafusp has been granted Fast Track Designation."

The FDA’s Fast Track program is designed to facilitate the development, and expedite the review of drugs to treat serious conditions and fill an unmet medical need. A drug granted Fast Track Designation may be eligible for several benefits, including more frequent meetings and communications with the FDA and, if relevant criteria are met, the potential for Accelerated Approval, Priority Review or Rolling Review of a Biologics License Application (BLA) or New Drug Application (NDA).

Tebentafusp has previously been granted orphan drug designation for melanoma by the US FDA and Promising Innovative Medicine designation under UK Early Access to Medicines Scheme.
