On its R&D Day in New York, entitled "Building Tomorrow’s Breakthroughs," the company elaborates on its refined development plans for its most advanced proprietary candidate MP0250 in multiple myeloma (MM). In particular, the company announces its intention to initiate a second phase 2 trial for MP0250 in MM. This complementary trial will recruit patients with relapsed or refractory MM who have failed at least two lines of therapy including a proteasome inhibitor and an immunomodulatory drug (IMiD) and in whom the most recent therapy was IMiD-based. Patients will be treated with MP0250 in combination with Pomalidomide and dexamethasone. The design of the initial phase 2 trial for MP0250 in MM will be updated to recruit patients with a proteasome inhibitor (PI) based regimen as the most recent therapy. Those patients continue to be dosed with MP0250 in combination with Velcade and dexamethasone.

Molecular Partners also presents additional preclinical data on MP0310, its most advanced multi-specific (FAP x 4-1BB) DARPin immuno-oncology compound, which is expected to move into the clinic in 2019. In addition, data on FAP x CD40, a second multi-specific preclinical DARPin therapeutic in immuno-oncology, will be presented.

"I am pleased to report on our progress in oncology and our efforts to build a sustainable pipeline of DARPin therapeutics," said Patrick Amstutz, Chief Executive Officer of Molecular Partners.

Pamela A. Trail, Chief Scientific Officer of the company, added: "Our unique DARPin designs have the potential to translate into novel therapeutics across the landscape of oncology. Going forward, we will focus on several key areas of therapeutic intervention which are in the sweet spot of our DARPin technology."

About the DARPin Difference
DARPin therapeutics are a new class of protein therapeutics opening an extra dimension of multi-specificity and multi-functionality. DARPin candidates are potent, specific, safe and very versatile. They can engage more than 5 targets at once, offering potential benefits over those offered by conventional monoclonal antibodies or other currently available protein therapeutics.
The DARPin technology is a fast and cost-effective drug discovery engine, producing drug candidates with ideal properties for development and very high production yields.

With their good safety profile, low immunogenicity and long half-life in the bloodstream and the eye, DARPin therapeutics have the potential to advance modern medicine and significantly improve the treatment of serious diseases, including cancer and sight-threatening disorders. Molecular Partners is partnering with Allergan to advance clinical programs in ophthalmology, and is advancing a proprietary pipeline of DARPin drug candidates in oncology and immuno-oncology. The most advanced global product candidate is abicipar, a molecule currently in phase 3, in partnership with Allergan. Several DARPin molecules for various ophthalmic indications are also in development. The most advanced DARPin therapeutic candidate wholly owned by Molecular Partners, MP0250, is in phase 2 clinical development for the treatment of solid tumors and hematological tumors. MP0274, the second-most advanced DARPin drug candidate owned by Molecular Partners, has broad anti-HER activity; it inhibits HER1, HER2 and HER3-mediated downstream signaling via Her2, leading to induction of apoptosis. MP0274 is currently in phase 1. Molecular Partners is also advancing a growing preclinical pipeline that features several immuno-oncological development programs. DARPin is a registered trademark owned by Molecular Partners AG

On December 6, 2018 Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in hematology and oncology, reported that data from the Phase 3 RECOVER clinical study was presented during the 2018 San Antonio Breast Cancer Symposium (SABCS) (Press release, Spectrum Pharmaceuticals, DEC 6, 2018, View Source [SID1234531926]). These data confirm the efficacy and safety of ROLONTIS (eflapegrastim) in reducing the Duration of Severe Neutropenia (DSN) in breast cancer patients treated with chemotherapy. ROLONTIS is a novel, long-acting granulocyte colony-stimulating factor (G-CSF) being studied as a treatment for neutropenia in patients undergoing treatment with myelosuppressive cytotoxic chemotherapy.

"Despite available treatments, neutropenia remains a critical issue for patients undergoing chemotherapy that puts them at risk for developing life threatening infections," said Lee Schwartzberg, MD, FACP, lead investigator, professor of medicine and division chief, hematology/oncology, University of Tennessee Health Science Center, and executive director, UT/West Cancer Center. "The robust data from both Phase 3 studies demonstrate that ROLONTIS has the potential to be a valuable option in the management of neutropenia for patients undergoing treatment with chemotherapeutic agents."

The data released yesterday in a poster presentation from the ROLONTIS Phase 3 RECOVER study (n=237) showed that in Cycle 1, the mean DSN±SD was 0.31±0.688 days for ROLONTIS and 0.39±0.949 days for pegfilgrastim, demonstrating non-inferiority (p<0.0001). The non-inferiority of ROLONTIS for DSN was maintained across all four treatment cycles (all (p<0.0001)). Incidence of severe neutropenia was 20 percent versus 24 percent in the eflapegrastim and pegfilgrastim arms respectively, with a relative risk reduction of 14 percent in favor of eflapegrastim. There were no statistically significant differences on secondary endpoints such as time to absolute neutrophil count (ANC) recovery, depth of ANC nadir, and incidence of febrile neutropenia between treatment arms across all cycles. None of the ≥Grade 3 study drug related adverse events (AE) occurred in >2% of the patients and included hematologic and bone pain related AEs in both arms.

The RECOVER trial is the second ROLONTIS Phase 3 study to meet the primary efficacy endpoint of non-inferiority in mean DSN. Results from ADVANCE, the first ROLONTIS Phase 3 study, were announced at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and presented at the Multinational Association in Supportive Care in Cancer Annual Meeting (MASCC) earlier this year.

"The RECOVER study is the second Phase 3 study to confirm non-inferiority data and comparable safety profile between ROLONTIS and the current standard of care," said Joe Turgeon, chief executive officer of Spectrum Pharmaceuticals. "Data from both studies, which enrolled 643 patients combined, will be used to support the BLA filing which is expected to be submitted by the end of the year. If approved, we look forward to having a unique opportunity to launch and compete in this large market with the first novel G-CSF in more than 15 years."

About RECOVER

The RECOVER study is a Phase 3, randomized, open-label, active-controlled, multicenter study that enrolled 237 breast cancer patients who received docetaxel and cyclophosphamide chemotherapy every 21 days. Patients were randomized in a 1:1 ratio to receive either ROLONTIS (n=118) or pegfilgrastim (n=119). The primary study endpoint was the DSN in Cycle 1 of chemotherapy (absolute neutrophil count [ANC] <0.5×109/L), based on central laboratory assessment of ANC over a 21 day cycle. There were a total of four cycles evaluated in this study. Secondary endpoints included, the DSN in Cycles 2, 3, and 4, time to ANC recovery, depth of ANC nadir and incidence of febrile neutropenia at cycle one. Patients with stage I to stage IIIA breast cancer were treated on day one of each of the four cycles with adjuvant/neo-adjuvant docetaxel and cyclophosphamide. On day two of each cycle, patients received a single subcutaneous dose of either eflapegrastim 13.2 mg/0.6 mL (equivalent to 3.6 mg G-CSF) or pegfilgrastim (6 mg).

Jeffrey Miller, MD, Deputy Director, Masonic Cancer Center, University of Minnesota commented, "These studies demonstrate the adaptability of the TriKE platform to optimize TriKE constructs and candidate selection in order to address unmet medical needs. We continue to work with our partners at GT Biopharma in moving the TriKE platform forward."

The Company’s TriKE product candidates are single-chain, tri-specific scFv recombinant fusion proteins composed of the variable regions of the heavy and light chains (or heavy chain only) of anti-CD16 antibodies, wild-type or a modified form of IL-15 and the variable regions of the heavy and light chains of an antibody designed to precisely target a specific tumor antigen. GT Biopharma utilizes the NK stimulating cytokine human IL-15 as a crosslinker between the two scFvs which is designed to provide a self-sustaining signal leading to the proliferation and activation of NK cells thus enhancing their ability to kill cancer cells mediated by antibody-dependent cell-mediated cytotoxicity (ADCC). GT Biopharma has an exclusive worldwide license agreement with the University of Minnesota to further develop and commercialize cancer therapies using proprietary TriKE technology developed by researchers at the university to target NK cells to cancer.

"We continue to be encouraged by the data from our Trike program being conducted by leading NK cell experts at the University of Minnesota. These findings have supported us with the confidence to proceed with our first-in-class TriKE, Phase 1 study," commented Raymond Urbanski, M.D., Ph.D., Chief Executive Officer of GT Biopharma. "We are grateful to renowned NK cell expert, Jeffrey Miller, MD, Deputy Director, Masonic Cancer Center, University of Minnesota and his team, and look forward to providing further updates as we continue to advance what we believe to be a potentially revolutionary product candidate."

Graduate student, Upasana Sunil Arvindam, MSc, BSc, working with Drs. Miller and Felices at the University of Minnesota, presented the abstract titled, "CD16-IL15-CLEC12A Tri-specific Killer Engager (TriKE) Drives NK Cell Expansion, Activation, and Antigen Specific Killing of Cancer Stem Cells in Acute Myeloid Leukemia," as part of the Acute Myeloid Leukemia: Novel Therapy, Excluding Transplantation: Poster I session at ASH (Free ASH Whitepaper). To access the presented poster, click here.

For the preclinical study, Dr. Arvindam and her team developed a 1615CLEC12A TriKE molecule to target AML cells using Natural Killer (NK) cells. This molecule contains an anti-CD16 camelid nanobody to activate NK cells, an anti-CLEC12A single chain variable fragment (scFv) to engage cancer targets, and an IL-15 molecule that drives NK cell priming, expansion and survival.

The CLEC12A TriKE was developed in a mammalian cell system to ensure that appropriate post-translational modifications are present. The researchers confirmed that the TriKE binds specifically to HL-60 and THP-1 target cells that express CLEC12A compared to Raji cells that do not express CLEC12A. Treatment of peripheral blood mononuclear cells (PBMCs) with the CLEC12A TriKE drives a significant increase in NK cell specific proliferation over 7 days as measured by Cell Trace dilution compared to treatment with a CLEC12A scFv or IL-15 alone (69.7 ± 6.7% vs 11.9 ± 2.5% vs 38.4 ± 7.3%). In these assays, the efficacy of the CLEC12A TriKE was comparable to the CD33 TriKE. The data demonstrates that the CLEC12A TriKE drives NK cell specific proliferation, degranulation, cytokine secretion, and killing of tumor targets in vitro. Apart from AML, CLEC12A is expressed on cancer cells and LSCs in patients with myelodysplastic syndromes (MDS).

The presented preclinical findings highlight the clinical potential of the CLEC12A TriKE individually or in combination with the CD33 TriKE for the treatment of MDS and AML and ultimately led to the establishment of a first-in-human Phase 1 study with GTB-3550 (OXS-3550), its first-in-class (TriKE), for the treatment of AML, MDS and mastocytosis, which GT Biopharma recently announced. The study will be led by Principal Investigator, Sarah A. Cooley, MD, MS, Associate Professor, Division of Hematology, Oncology and Transplantation at Masonic Cancer Center, University of Minnesota.

The abstract titled, "Induced Pluripotent Stem Cell-Derived NK Cells Genetically Modified to Express NKG2C/DAP12 Mediate Potent Function When Targeted through an NKG2C/IL-15/CD33 Tri-Specific Killer Engager (TriKE)," was presented in an oral presentation by graduate student Emily Chiu, PhD, Medical School, University of Minnesota. To access the presentation slides, click here.

Having demonstrated stable expression and intact signaling of NKG2C/DAP12 in iNK cells, Dr. Chiu and her team next created a TriKE molecule with single chain Fv fragments specific for NKG2C (on iNK cells) and CD33 (on AML cells), as well as IL15 (to support iNK cell survival and proliferation). Without the addition of NKG2C/CD33/IL15 TriKE, the frequencies of both NKG2C iNK cells and NKG2C/DAP12 iNK cells producing IFNg was relatively low (< 10%). Addition of NKG2C/IL15/CD33 TriKE in the assay markedly increased the frequency of IFNg production by both NKG2C iNK cells (19.1%) and NKG2C/DAP12 iNK cells (25.8%). Finally, the team directly tested the ability of the NKG2C/IL15/CD33 TriKE molecule to trigger target killing by engineered iNK cells monitored over a 24hour period. THP1 target cells were dye labeled and plated in wells with either NKG2C iNK cells or NKG2C/DAP12 iNK cells at a 5:1 effector-to-target ratio with or without NKG2C/CD33/IL15 TriKE. The researchers found that in the absence of TriKE, there was no killing of THP1 targets. In contrast, both NKG2C iNK cells and NKG2C/DAP12 iNK cells mediated robust THP1 killing with the addition of NKG2C/CD33/IL15 TriKE, with NKG2C/DAP12 iNK cells exhibiting the strongest response.

Results from the study provided a proof-of-concept that iNK cells engineered to express NKG2C/DAP12 can be used in combination with a novel NKG2C/IL15/CD33 TriKE molecule to effectively target cancer cells. Engaging NK cells through NKG2C, restricted to adaptive NK cells or genetically modified iPSC will be more specific than CD16, which will bind to CD16A on NK cells but also have off-target binding to CD16B on neutrophils. Because of the enormous expansion and engineering capacity of the iNK cell platform, the Company believes it is in a unique position to create an "off-the-shelf" NK cellular therapy that is targeted, specific and efficacious.

About Acute Myelogenous Leukemia (AML)

AML is the most common form of adult leukemia with 21,000 new cases expected in 2018 alone, according to the American Cancer Society. AML patients typically receive frontline therapy, most commonly chemotherapy, which includes cytarabine and an anthracycline, a therapy that has not changed in over 40 years. However, there remains a significant unmet need in these therapies with about half of AML patients experiencing relapses or requiring alternative therapies. The Company is developing GTB-3550 to serve as a relatively safe, cost-effective, and easy-to-use therapy for resistant/relapsing AML and could also be combined with chemotherapy as frontline therapy thus targeting the larger patient population

On December 6, 2018 Moleculin Biotech, Inc., (Nasdaq: MBRX) ("Moleculin" or the "Company"), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, reported it has filed a request with the U.S. Food and Drug Administration ("FDA") for Orphan Drug Status for its drug candidate WP1066 (Press release, Moleculin, DEC 6, 2018, View Source [SID1234531927]).

"Clinical progress with WP1066 has been encouraging," commented Walter Klemp, Moleculin’s Chairman and CEO. "Given its potential to address rare and difficult to treat cancers, including glioblastoma, we believe WP1066 is well positioned to qualify for Orphan Drug Status."

The FDA grants orphan drug designation to drugs and biologics that are intended for the treatment of rare diseases that affect fewer than 200,000 people in the U.S. Orphan drug status is intended to facilitate drug development for rare diseases and may provide several benefits to drug developers, including tax credits for qualified clinical trials costs, exemptions from certain FDA application fees, and seven years of market exclusivity upon regulatory product approval.
