The financing announced today is intended to fuel development of innovative product candidates across multiple aspects of transplantation medicine, including more precise preparation of patients, stem cell harvesting and stem cell expansion. The Series B round, which was oversubscribed, was led by GV (formerly Google Ventures), with participation from all existing investors, including Atlas Venture, Third Rock Ventures, Partners Innovation Fund and Access Industries. The financing also included Casdin Capital and other crossover investors, as well as Be The Match BioTherapies, a subsidiary of National Marrow Donor Program (NMDP)/Be The Match, the world’s leading organization focused on saving lives through bone marrow and umbilical cord blood transplantation.

"Magenta has quickly established itself as a nexus of innovation in stem cell science, catalyzing interest in this area of medicine with the recognition that improvements will have profound impact on patients," said Jason Gardner, D. Phil., chief executive officer, president and cofounder of Magenta Therapeutics. "We aspire to accelerate products that could unleash the potential of transplantation to more patients, including those with autoimmune diseases, genetic blood disorders and cancer. The resounding interest in Magenta from such a high-quality set of investors is a testament to our solid progress since launch, including building a world-class team and a robust pipeline, and generating promising early data."

MGTA-456: Investigational Product Addressing Significant Unmet Need in Stem Cell Transplant
The clinical-stage program in-licensed by Magenta from Novartis, MGTA-456 (formerly HSC835), aims to expand the number of cord blood stem cells used in transplants to achieve superior clinical outcomes compared to standard transplant procedures, and to enable more patients to benefit from a transplant. Under this agreement, Magenta gains rights to use MGTA-456 in selected applications and will develop MGTA-456 in multiple diseases, including immune and blood diseases.

Early results published in Science[1] demonstrated the ability of MGTA-456 to significantly increase the number of umbilical cord blood stem cells. Clinical results reported in Cell Stem Cell[2] demonstrated that this approach yielded an increased expansion of stem cells.

John E. Wagner, M.D., executive medical director of the Bone Marrow Transplantation Program at the University of Minnesota and the study’s lead author, stated: "MGTA-456 markedly shortens time to recovery, addressing one of the most significant challenges in stem cell transplantation today. MGTA-456 achieved a remarkable increase in the number of blood-forming stem cells, greater than that observed by all other methods that have been tested to date. This product has the potential to further improve cord blood transplant outcomes."

Be The Match BioTherapies Strategic Partnership Agreement
Magenta and Be The Match BioTherapies also announced today that in addition to the equity investment, the two organizations have initiated a collaboration to support their shared goals of improving transplant medicine. Magenta and Be The Match BioTherapies will explore opportunities to work together across all of Magenta’s research efforts, from discovery through clinical development. Under this agreement, Magenta may leverage Be The Match BioTherapies’ capabilities, including its cell therapy delivery platform, industry relationships, clinical trial design and management, and patient outcomes data derived from the NMDP/Be The Match, which operates the largest and most diverse marrow registry in the world. NMDP/Be The Match has a network of more than 486 organizations that support marrow transplant worldwide, including 178 transplant centers in the United States and more than 45 international donor centers and cooperative registries.

"We are proud to have made our first equity investment as an organization in Magenta Therapeutics, and we share a vision to improve and advance the use of curative stem cell transplantation for patients with a wide range of diseases," said Amy Ronneberg, president of Be The Match Biotherapies.

Advancing number of programs in clinical trials reflects operational progress and maturing pipeline

Conference call and webcast (in English) at 3:00pm CEST (2:00pm BST/9:00am EDT)

MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX; OTC: MPSYY), a leader in the field of therapeutic antibodies, today reported results for the first quarter of 2017.

"We have seen significant progress both with our own and our partners’ drug candidates in the first quarter of 2017. This was particularly evidenced by our partner Roche’s decision to start a new pivotal phase 3 program with the antibody gantenerumab in Alzheimer’s disease," said Dr. Simon Moroney, Chief Executive Officer of MorphoSys AG. "We expect 2017 to be a year rich in clinical read-outs from our pipeline, with key data from several phase 2 studies pending. We are optimistic about the market approval of guselkumab, an antibody against psoriasis being developed by our partner Janssen, which is under FDA review for approval with a decision expected in the second half of this year."

"If approved, guselkumab could start to contribute to our earnings in the form of royalties on product sales most likely starting early 2018," commented Jens Holstein, Chief Financial Officer of MorphoSys AG. "With our strong cash position, we will continue to drive forward our proprietary portfolio of innovative biopharmaceuticals for the treatment of serious diseases, in particular starting a phase 3 trial with our blood cancer candidate MOR208 this year. In addition, we expect that our maturing partnered portfolio will produce increasing cash inflows from royalties in the years to come."

Financial Review for Q1 2017 (IFRS)

In Q1 2017 MorphoSys continued to focus on the research and development of drug candidates both for its own account as well as with its partners. Group revenues amounted to EUR 11.8 million, in line with the level of the first quarter of 2016 (EUR 12.1 million).

In the Proprietary Development segment, MorphoSys focuses on the research and clinical development of its own drug candidates in the fields of cancer and inflammation. In Q1 2017, this segment recorded revenues of EUR 0.2 million (Q1 2016: EUR 0.1 million).

In the Partnered Discovery segment, MorphoSys applies its proprietary technology to discover new antibodies for pharmaceutical companies, benefiting from the partners’ development progress through success-based milestone payments and royalties. In Q1 2017, revenues in this segment reached EUR 11.6 million (Q1 2016: EUR 12.0 million).

Earnings before interest and taxes (EBIT) in Q1 2017 stood at EUR -14.9 million (Q1 2016: EUR – 9.7 million). As expected, the operational loss reflects increased activities in the clinical development of the Company’s proprietary drug candidates, in particular three phase 2 studies started with MOR208 in blood cancer indications after the end of Q1 2016. Accordingly, the Proprietary Development segment reported an EBIT of EUR -18.9 million after being EUR -14.3 million in Q1 2016. EBIT in the Partnered Discovery segment was EUR 7.3 million (Q1 2016: EUR 7.7 million).

In Q1 2017, the consolidated net result amounted to EUR -15.0 million (Q1 2016: EUR -7.2 million). The diluted net result per share for Q1 2017 was EUR -0.52 (Q1 2016: EUR -0.28).

At the end of Q1 2017, the Company had a cash position of EUR 349.9 million compared to EUR 359.5 million on December 31, 2016. On the balance sheet, this cash position is reported under the items: cash and cash equivalents; available-for-sale financial assets; bonds, available-for-sale; and current and non-current financial assets classified as loans & receivables.

The number of shares issued totaled 29,159,770 at the end of Q1 2017 (year-end 2016: 29,159,770).

Financial Guidance and operational outlook for 2017

For the financial year 2017, MorphoSys continues to expect Group revenues in the range of EUR 46 to 51 million. R&D expenses for proprietary drug development are confirmed to be in a corridor of EUR 85 to 95 million. The Company confirmed its guidance for earnings before interest and taxes (EBIT) of EUR -75 to -85 million. This guidance does not include any additional revenue from potential future collaborations and/or licensing partnerships nor effects from potential in-licensing or co-development deals for new development candidates.

In the Proprietary Development segment, MorphoSys expects the following events in 2017:

– MOR208: Completion of the phase 2 safety run-in of the B-MIND clinical trial and initiation of the pivotal phase 3 part of the study, in which MOR208 will be tested in combination with bendamustine in comparison to rituximab and bendamustine in DLBCL.

– MOR208: Presentation of first data from the phase 2 trial of MOR208 in combination with lenalidomide in DLBCL (L-MIND study).

– MOR208: Initiation of the second study arm of the ongoing phase 2 COSMOS trial with MOR208 in CLL in order to test MOR208 with venetoclax. Currently, the Company is investigating the combination of MOR208 and idelalisib in this study.

– MOR202: Completion of the phase 1/2a dose-escalation trial in multiple myeloma, including MOR202 in combinations with pomalidomide and with lenalidomide.

– MOR209/ES414: Continuation of the phase 1 trial of MOR209/ES414 with an adapted dose regimen in prostate cancer (mCRPC) as part of the collaboration with Aptevo.

– MOR106: Completion of the phase 1 trial of MOR106, co-developed with Galapagos, in atopic dermatitis.

– MOR107: Completion of a phase 1 study in healthy volunteers.

– MOR103/GSK3196165: MorphoSys expects data from a phase 2b study in rheumatoid arthritis and from a phase 2a study in hand osteoarthritis, both conducted by GSK. This HuCAL antibody originated in the Company’s Proprietary Development segment, and has been fully out-licensed to GSK.

In its Partnered Discovery segment, MorphoSys expects the following events in 2017:

– Guselkumab: the first partner-developed therapeutic antibody based on MorphoSys’s HuCAL technology could receive market approval in 2017. MorphoSys expects the US regulatory authority FDA to make a decision in the second half of 2017 on Janssen’s application for the approval of guselkumab to treat adults with moderate to severe psoriasis. In addition, a regulatory filing for guselkumab in Europe has been submitted.

– Anetumab ravtansine, a HuCAL antibody drug conjugate being developed by Bayer, is expected to report results in 2017 from a pivotal phase 2 trial in the cancer indication mesothelioma. Favorable results could support a regulatory filing of the compound.

– Novartis collaboration: As previously communicated and as reflected in the Company’s 2017 guidance, the collaboration with Novartis will conclude at the end of November 2017 in accordance with the contract.

– For the remaining year, results may be disclosed from up to 27 different clinical studies in various phases conducted by partners with antibodies based on MorphoSys technology.

As always, MorphoSys is in discussions with other companies in the pharmaceutical industry about technology and/or product-based collaborations, with the goal of strengthening its participation in drug programs aimed at unmet medical needs.

Selecta Biosciences Obtains License for Recombinant Immunotoxin LMB-100 from National Cancer Institute (NCI) for Pancreatic Cancer, Mesothelioma and Other Cancers

On May 2, 2017 Selecta Biosciences, Inc. (NASDAQ:SELB), a clinical-stage biopharmaceutical company focused on unlocking the full potential of biologic therapies by avoiding unwanted immune responses, reported that it has licensed LMB-100, a next-generation immunotoxin, from the Center for Cancer Research (CCR) at the NCI, part of the National Institutes of Health. LMB-100 contains a potent bacterial toxin that binds to mesothelin, a protein expressed in all mesotheliomas, pancreatic adenocarcinomas and a high percentage of other malignancies, including lung, breast and ovarian cancers.

"This marks yet another major milestone for Selecta as we execute on our strategy to enable a range of proprietary, non-immunogenic biologic therapies using our proprietary immune tolerance platform," said Werner Cautreels, Ph.D., President, CEO and Chairman of Selecta. "By in-licensing this promising clinical-stage product candidate, we are extending our footprint to include oncology, where the efficacy of many biologic treatments is hampered by immunogenicity. Based on our preclinical work with NCI, we believe a combination treatment of LMB-100 and our proprietary SVP-Rapamycin may allow patients with rare, serious and aggressive forms of cancer to tolerate and benefit from multiple immunotoxin treatment cycles."

CCR is in the process of completing two clinical trials of LMB-100 in patients with mesothelioma and pancreatic cancer that are intended, in part, to help define the maximum tolerated dose. For more information about these trials, call 1-800-4-Cancer (1-800-422-6237) (TTY: 1-800-332-8615) and/or visit View Source Initial data indicate that undesired antibody responses to the immunotoxin prevented most patients from receiving the intended four treatment cycles. While a precursor to LMB-100 was similarly restricted by immunogenicity despite the concurrent use of potent immunosuppressive drugs, tumor regression was observed in the only two patients who were able to receive more than two cycles of treatment. These results suggest that the mitigation of immunogenicity may enable more patients to benefit from LMB-100 therapy.

In 2016, preclinical research under a Cooperative Research and Development Agreement between Selecta and NCI demonstrated that the co-administration of SVP-Rapamycin and LMB-100 has the potential to enable extended treatment with LMB-100 and, therefore, enhance its anti-tumor activity. Selecta’s immune tolerance Synthetic Vaccine Particles (SVP) prevented the formation of anti-LMB-100 antibodies, allowing for the administration of repeat treatment cycles in mouse models and enabling the full beneficial effect of LMB-100 on tumors in a tumor model. Selecta and NCI are currently in discussions regarding a planned Phase 1b clinical trial to evaluate multiple cycles of this combination treatment.

Under the terms of the license agreement, NCI will receive an upfront payment of $50,000 from Selecta. NCI also is entitled to up to $9.25 million in payments for milestones and low single-digit royalties on worldwide annual net sales of any resulting commercialized treatment.

About Pancreatic Cancer and Mesothelioma

Pancreatic cancer is among the most commonly diagnosed cancers and it is one of the few that is increasing in incidence and mortality. This type of cancer virtually always expresses mesothelin and has been linked to smoking, obesity and diabetes. For the year 2016, the National Cancer Institute (NCI) estimates that more than 53,000 new U.S. cases of pancreatic cancer were reported and that there were nearly 42,000 deaths in the U.S. from this disease. The prognosis for pancreatic cancer is poor, with approximately five percent of patients surviving five or more years following diagnosis.

Mesothelioma is a mesothelin-expressing cancer predominantly affecting the layer of tissue lining the lungs and chest wall. This type of cancer has been linked to asbestos exposure. According to the American Cancer Society, approximately 3,000 people are diagnosed with this disease each year in the United States. The prognosis for mesothelioma is poor, with an average life expectancy of 12-18 months following diagnosis.

Altor BioScience Corporation Announces FDA Fast Track Designation for Lead Candidate ALT-803 in Patients with Non-Muscle Invasive Bladder Cancer

On May 2, 2017 Altor BioScience Corporation (Altor), a leading developer of novel cytokine-based immunotherapeutics for cancer and infectious diseases, reported that it has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for its investigational interleukin-15 (IL-15) agonist complex, ALT-803, in combination with bacillus Calmette-Guérin (BCG), for the treatment of patients with non-muscle invasive bladder cancer (NMIBC) (Press release, Altor BioScience, MAY 2, 2017, View Source [SID1234518799]). The FDA’s Fast Track program is designed to expedite the development and review of drugs to treat serious conditions and fill unmet medical needs.

ALT-803 is currently being evaluated in a Phase Ib/II clinical trial to investigate the safety and efficacy of intravesical ALT-803 in combination with BCG in adult patients with BCG-naïve NMIBC as well as a separate Phase II clinical trial to investigate the safety and efficacy of intravesical ALT-803 in combination with BCG in adult patients with BCG-unresponsive NMIBC. Results from the recently completed Phase Ib NMIBC study will be presented at the American Urological Association Annual Meeting in Boston on May 12, 2017. The FDA Fast Track designation will apply to clinical development of ALT-803 in combination with BCG for the treatment and prophylaxis of carcinoma in situ (CIS) of the urinary bladder, as well as for the prophylaxis of primary or recurrent stage Ta and/or T1 papillary tumors following transurethral resection (TUR) in patients with NMIBC.

Hing C. Wong, Ph.D., Chief Executive Officer of Altor BioScience, said: "We are thrilled that the FDA has granted Fast Track designation for ALT-803 in NMIBC. This is a key milestone for advancing our NMIBC program. Patients with NMIBC have few treatment options and there is a significant unmet medical need for novel therapies in NMIBC, particularly in patients who are unresponsive to BCG. We are looking forward to working closely with FDA to facilitate our clinical program in this important indication."

About ALT-803

ALT-803 is a proprietary, novel IL-15 superagonist complex, which demonstrates improved pharmacokinetic properties and enhanced anti-tumor activity compared to IL-15 in preclinical studies. These studies also demonstrated that ALT-803 simultaneously mobilizes both the innate and adaptive arms of the immune system to elicit rapid, robust, and long-lasting responses against cancer and virally-infected cells. ALT-803 also potently activates NK cells and enhances antibody-dependent cell-mediated cytotoxicity (ADCC) of antibodies in various experimental models. Combination studies of ALT-803 with antibodies, targeted agents, and vaccines are underway and will further explore the role of ALT-803 in immunotherapy combinations for various disease indications. ALT-803 is currently being evaluated in multiple clinical trials for patients with solid or hematological tumors and in HIV infected individuals.
