"We are pleased that, with this change, patients in the U.S. receiving their first infusion of DARZALEX may now have this more flexible dosing option," said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab

This approval was supported by data from the Phase Ib EQUULEUS (MMY1001) clinical trial, which demonstrated DARZALEX pharmacokinetics (PK) concentrations were comparable regardless of whether the first dose was administered as a split infusion or as a single first infusion in patients with multiple myeloma. The safety profile of DARZALEX was comparable when administered initially as either a split or a single dose.

About the EQUULEUS (MMY1001) Study
The Phase Ib EQUULEUS open-label study includes up to 240 patients with the goal of evaluating the safety, tolerability and dose of daratumumab when administered in combination with various backbone treatment regimens for different settings of multiple myeloma.

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.1 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).1,2,3,4,5

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.

Prostate cancer is a leading cause of cancer death in men. While most primary prostate cancer can be successfully treated, recurrence occurs in up to one-third of patients. Recurrent disease is typically detected by a rise in PSA levels but often the location and extent of the disease cannot be detected by conventional imaging. Of those who suffer biochemical recurrence, approximately one-third develop metastatic prostate cancer. Axumin was developed to target the increased amino acid transport that occurs in many cancers, including prostate cancer. It is labelled with the radioisotope (18F), enabling it to be visualized in the body with PET imaging.

Dr. Jonathan Allis, Chief Executive Officer of Blue Earth Diagnostics said, "Detection and localization of recurrent prostate cancer is a significant unmet medical need, and Blue Earth is committed to maximizing access to Axumin to clinicians and their patients across Europe. Today’s announcement is key milestone towards our goal."

Second Quarter Fiscal 2019 Financial Results
Palatin reported a net loss of $(5.0) million, or $(0.02) per basic and diluted share, for the quarter ended December 31, 2018, compared to net income of $3.0 million, or $0.02 per basic and $0.01 per diluted share, for the same period in 2017.

The difference in financial results between the three months ended December 31, 2018 and 2017 was primarily attributable to the recognition of $10.6 million in license and contract revenue during the 2017 period pursuant to our license agreement with AMAG.

Revenue
There were no revenues recorded in the quarter ended December 31, 2018.

For the quarter ended December 31, 2017, 100% of the revenue Palatin recognized was related to our license agreement with AMAG.

Operating Expenses
Total operating expenses for the quarter ended December 31, 2018 were $5.1 million compared to $7.7 million for the comparable quarter of 2017. The decrease in operating expenses was mainly attributable to the completion of the Vyleesi Phase 3 clinical trial program and ancillary studies necessary to file the NDA in HSDD in March 2018.

Other Income/Expense
Total other income, net was $7,871 for the quarter ended December 31, 2018 compared to total other expenses, net $(0.3) million for the quarter ended December 31, 2017. The difference is related primarily to the decrease in interest expense related to Palatin’s venture debt.

Income Tax
There was no income tax expense, or benefit, recorded in the quarter ended December 31, 2018.

Pursuant to the license agreements with Fosun and Kwangdong, $500,000 and $82,500, respectively, was withheld in accordance with tax withholding requirements in China and the Republic of Korea, respectively, and was recorded as an expense during the fiscal year ended June 30, 2018. For the quarter ended December 31, 2017, Palatin recorded $100,880 in income tax expense related to those withholding amounts utilizing an estimated effective annual income tax rate applied to income for the quarter and the remaining balance of $256,365 was included in prepaid expenses and other current assets at December 31, 2017. Any potential credit to be received by Palatin on its United States tax returns is currently offset by Palatin’s valuation allowance. The $100,880 of income tax expense was offset by a $500,000 tax benefit that Palatin recorded in the quarter ended December 31, 2017 related to the release of a valuation allowance against Palatin’s federal alternative minimum tax credit as a result of the Tax Cuts and Jobs Act signed in December 2017. Accordingly, $500,000 was included in other long-term assets at December 31, 2017.

Cash Position
Palatin’s cash, and cash equivalents were $24.7 million as of December 31, 2018, compared to cash and cash equivalents of $38.0 million at June 30, 2018. Current liabilities were $4.5 million as of December 31, 2018, compared to $10.8 million as of June 30, 2018.

Palatin believes that existing capital resources will be sufficient to fund our planned operations through at least March 31, 2020.

Greywolf’s novel approach is aimed at directly altering tumour cells, illuminating them for attack and destruction by the immune system. The goal is to exploit this increased tumour visibility in monotherapy and to extend the therapeutic benefit of already approved immunotherapies to many more cancers.

Greywolf is developing small molecule modulators of endoplasmic reticulum aminopeptidases (ERAPs), key proteins in the antigen presentation pathway, to change the neoantigen repertoire in tumours and thereby increase the number and range of neoantigens presented on tumour cells available to engage an immune response.

This unique small molecule immuno-oncology approach builds on the exciting recent advances in cancer immunotherapies that address a key limiting factor for approved treatments, while avoiding the complex and costly personalisation required for other approaches such as neoantigen vaccines.

Greywolf has programs targeting the two homologues of ERAP, ERAP1 and ERAP2, aimed at developing potent and selective modulators, with the lead program being against ERAP1.

Greywolf was co-founded by Peter Joyce, former Project Leader at Vertex Pharmaceuticals, and Tom McCarthy, former President and CEO of Spinifex Pharmaceuticals, and comprises a team of world-leading experts in immuno-oncology, antigen presentation and drug discovery. It is working with the University of Oxford, University of Southampton and has a strategic partnership with Sygnature Discovery, a leading independent provider of drug discovery resources and expertise. Sygnature is also an investor in the Company.

Peter Joyce, Chief Executive Officer of Greyw‍olf Therapeutics, said: "The recent breakthroughs in immunotherapy have fundamentally changed the treatment landscape in oncology, but the fact remains that current approaches only target the minority of tumours that are visible to the immune system, whilst the vast majority of cancers do not respond. There is strong validation for targeting ERAPs to increase tumour visibility and with these funds we are now positioned to build on our existing work and collaborations to deliver a clinical candidate in the coming two to three years."

Tom McCarthy, Executive Chairman of Greywolf Therapeutics, said: "Attracting investors of the calibre of Andera and Canaan is a strong validation of the potential of our approach to broaden the effectiveness of immunotherapy. We believe we have a truly novel approach in targeting tumours themselves, rather than direct regulation of the immune system, and I am excited by the opportunity to work with our investors and talented team on the next steps of Greywolf’s development."

Thierry Hercend, Venture Partner at Andera Partners, said: "Greywolf has identified a highly innovative approach to immuno-oncology and, in Peter and Tom, has founders with very strong scientific and entrepreneurial credentials. With the support of Sygnature, they achieved a significant amount with their seed funding and demonstrated a scientifically rigorous and nimble approach to drug development which we value. I’m confident that with this series A financing, Greywolf will deliver on the full potential of ERAP modulation."

Brent Ahrens, General Partner at Canaan, said: "Greywolf marks Canaan’s first investment in the UK biotechnology sector, and we are excited by the Company’s science and its potential to help the huge numbers of patients yet to receive any benefit from current oncology treatment options."

Raphaël Wisniewski, Partner at Andera, Thierry Hercend, Venture Partner at Andera and Brent Ahrens, General Partner at Canaan have joined Greywolf’s Board of Directors.

On February 11, 2019 NeoTX Therapeutics, Ltd reported that it has entered into a clinical collaboration with AstraZeneca Group Plc (NYSE: AZN) global biologics research and development arm, MedImmune, to support Phase 1b/2 studies investigating NeoTX’s naptumomab estafenatox ("naptumomab") in combination with IMFINZI (durvalumab) (Press release, NeoTX, FEB 11, 2019, View Source [SID1234640360]). These studies are expected to begin in 2019. Naptumomab is the lead drug in NeoTX’s novel Selective T cell Redirection ("STR") platform.

Naptumomab’s dual mechanism of action coats the tumor with a target that can be easily identified by T cells and then primes and redirects specific activated T cells that can identify that target, to the tumor.

Durvalumab is a human monoclonal antibody that blocks the immune checkpoint protein, programmed death-ligand (PD-L1), and allows activated T cells to attack tumor cells.

The Phase 1b/2 studies will determine the maximum tolerated dose (MTD) of naptumomab in combination with durvalumab, evaluate the clinical response, safety and tolerability of the combination, as well as test for multiple pharmacodynamic parameters.

Under terms of the agreement, NeoTX and AstraZeneca will collaborate on a non-exclusive basis to evaluate the combination of the two drugs in solid tumors. NeoTX will sponsor the study, while AstraZeneca will supply durvalumab. Up to 195 patients are planned to be enrolled in this multicenter, open-label study.

"We are pleased to work with AstraZeneca addressing the high unmet medical need of patients with tumors for which checkpoint inhibitor therapy has had little success," said Asher Nathan, NeoTX Therapeutics’ Chief Executive Officer. "The safety profile of naptumomab alone and in combination with interferon has been demonstrated in clinical studies in hundreds of patients with solid tumors. Naptumomab can enhance T cell activation and infiltration in tumors and can remodel the immunosuppressive tumor microenvironment. In preclinical models, naptumomab has a synergistic effect with checkpoint inhibitors which could translate into durable responses in patients."
