"As part of our overarching research and development strategy, Amgen is committed to advancing multiple modalities to gain biological insights before selecting the optimal treatment approach," said David M. Reese, M.D., senior vice president of Translational Sciences and Oncology at Amgen. "With a variety of tools in our toolkit, we have the ability to comprehensively evaluate these novel approaches to determine how each may perform in different treatment settings. We look forward to seeing how the pre-clinical data ultimately translate in the clinic."

Research presented at the meeting will also include pre-clinical studies examining pharmacodynamic markers for Mcl-1 inhibition, as well as the combination of Amgen’s Mcl-1 inhibitor (AMG 176) with a selective BCL-2 inhibitor in models of AML. AMG 176 is a highly selective and reversible Mcl-1 inhibitor and is being studied in a Phase 1 clinical trial involving patients with relapsed or refractory AML or multiple myeloma. Studies have shown that hematologic malignancies including AML, multiple myeloma and non-Hodgkin lymphoma are particularly sensitive to Mcl-1 inhibition.

In addition, Amgen will present for the first time pre-clinical data evaluating its half-life extended (HLE) anti-BCMA BiTE for the treatment of multiple myeloma. A phase 1 study evaluating Amgen’s anti-BCMA HLE-BiTE (AMG 701) is ongoing.

With the exception of late-breaking research, abstracts are available and can be reviewed on the AACR (Free AACR Whitepaper) website at View Source Identified below are select abstracts of interest on Amgen research:

About CAR T Cell Therapy
CAR T cell therapy is an evolving area of personalized medicine in which a patient’s own T cells (a type of white blood cell) are engineered to recognize tumor-specific antigens and incite an immune system attack against the cancer cells. Amgen is exploring the application of CAR T cell therapy across hematologic and solid tumor malignancies. Amgen and Kite Pharma, a subsidiary of Gilead Sciences Inc., are collaborating on engineering and commercializing Car T cell therapies.

About BiTE Technology
Bispecific T cell engager (BiTE) antibody constructs are a type of immunotherapy being investigated for fighting cancer by helping the body’s immune system to detect and target malignant cells. The modified antibodies are designed to bridge T cells to tumor cells, using the patient’s own immune system to eradicate cancer. BiTE antibody constructs help place the T cells within reach of the targeted cell, with the intent of allowing T cells to inject toxins and trigger the cancer cell to die (apoptosis). BiTE antibody constructs are currently being investigated for their potential to treat a wide variety of cancers.

About Amgen’s Commitment to Oncology
Amgen Oncology is committed to helping patients take on some of the toughest cancers, such as those that have been resistant to drugs, those that progress rapidly through the body and those where limited treatment options exist. Amgen’s supportive care treatments help patients combat certain side effects of strong chemotherapy, and our targeted medicines and immunotherapies focus on more than a dozen different malignancies, ranging from blood cancers to solid tumors. With decades of experience providing therapies for cancer patients, Amgen continues to grow its portfolio of innovative and biosimilar oncology medicines.

Persons, who on the record date 16 May 2018 are shareholders of RhoVac, have pre-emptive rights to subscribe for new shares in the rights issue, whereby six (6) existing shares entitle to subscription for one (1) new share at a subscription price of SEK 18 per share. The subscription period runs from 18 May 2018 up to and including 1 June 2018.

The rights issue is secured up to 80 percent through subscription undertakings on approximately 6.0 MSEK equal to approximately 24.4 percent and entered guarantee undertakings on approximately 13.6 MSEK equal to approximately 55.6 percent. All the members of the Board of Directors and senior executives participate through subscription undertaking. All external investors who entered guarantee undertakings also participate through subscription undertaking.

Background and reasons

RhoVac is a biotechnology company conducting research and development of an immunotherapeutic cancer vaccine. The Company’s primary focus is the development of the drug candidate RV001 with the potential to prevent or limit the spread and recurrence of cancer in the treatment of several different cancer indications. The Company’s development strategy is based on licensing or selling all or parts of the business as soon as possible after completion of clinical phase I/II trial regarding RV001. As the ongoing phase I/II study is in its final stages, RhoVac is investing aggressively in its business development through, among other things, to, as previously announced, employ David Colpman at Colpman Consulting Ltd. The reason for the rights issue of approximately SEK 24.5 million at full subscription (before issue costs) is to primarily strengthen the business development with the purpose of identifying possible licensing opportunities or partnerships, follow-up of clinical phase I/II study, regulatory preparations for a clinical phase IIb study and general working capital required.

A fully subscribed rights issue would provide the Company with SEK 21.5 million (after issue costs), which exceeds the Company’s capital requirements over the next 12 months. In this case, the Company will adjust scheduled activities and allocation of capital taking into account the status of potential licensing and partnership discussions. Focus will be on activities that at the time are deemed most relevant in order to increase the value of the Company. In a step to further strengthen the business development in the next 12 months, the Board will propose Gunnar Gårdemyr as a new Board member at the AGM. The Company wishes to use Mr. Gårdemyr’s extensive experience and contact network in the Life Science area to further strengthen the Company’s business development.

The rights issue

On 9 April 2018, the board of directors of RhoVac AB resolved to propose the annual general meeting of 9 May 2018 to resolve on a new share issue with pre-emptive rights for the Company’s existing shareholders of approximately SEK 24.5 million before issue costs. Persons, who on the record date 16 May 2018 are shareholders of RhoVac, have pre-emptive rights to subscribe for new shares in the rights issue, whereby six (6) existing shares entitle to subscription for one (1) new share (i.e. a 1:6 subscription ratio).

The subscription price amounts to SEK 18.00 per share. The subscription period runs from and including 18 May up to and including 1 June 2018. Through the rights issue, not more than 1,360,507 new shares will be issued, corresponding to a share capital increase of SEK 244,891.26.

Subscription and guarantee undertakings

The rights issue is secured through subscription and guarantee undertakings up to 80 percent of the rights issue, corresponding to approximately SEK 19.6 million. RhoVac has received subscription undertakings of approximately SEK 6.0 million, corresponding to approximately 24.4 percent of the rights issue, from all the members of the Board of Directors and senior executives and, in particular, from a limited number of external investors by overtaking subscription rights. In addition, the Company has received guarantee undertakings of approximately SEK 13.6 million, corresponding to approximately 55.6 percent of the rights issue, whereof all of them have agreed to takeover subscription rights.

Shareholders who choose not to participate in the rights issue will have their shareholdings diluted by approximately 14.3 percent but are able to fully or partially financially compensate for this dilution by selling their subscription rights. In the event that all shares are not subscribed for with subscription rights, the board will, within the framework of the maximum amount of the rights issue, decide on the allotment of shares subscribed for without subscription rights

The rights issue is subject to approval from the annual general meeting of 9 May 2018. The convening notice of the annual general meeting is announced through a separate press release.

The full terms and conditions of the rights issue, as well as other information about the Company, will be outlined in an information memorandum, which will be published prior to the commencement of the subscription period.

About Muscle Invasive Bladder Cancer

Bladder cancer is the fifth most common neoplasm in industrialized countries, affecting roughly 2.7 million people worldwide. In the United States, there were an estimated 79,000 new cases and nearly 17,000 deaths in 2017; Muscle Invasive Bladder Cancer (MIBC) accounts for 20-25% of the newly diagnosed cases and the majority of disease-related mortality.

While some potentially curative treatments, including surgical organ removal and chemoradiation, are available, 40% or more of patients with MIBC are unfit to undergo these morbid procedures, or opt to not receive them.i Available treatment options for these patients are limited to palliative care.

About TAR-200 (GemRIS)

TAR-200 is TARIS’s lead investigational program in bladder cancer, and is designed to release the chemotherapeutic agent gemcitabine continuously in the bladder for multiple weeks.
