This selection underscores the heightening awareness of the disease – BPDCN, the target – CD123, and the clinical impact of the drug candidate – ELZONRIS. In addition, our regulatory team continues to work diligently in an effort to make ELZONRIS available to patients as quickly as possible, and our commercial team continues to execute on our broad-based pre-launch initiatives. This includes the build-out of our sales, marketing and reimbursement teams as well as continuing to advance our disease awareness campaign. In parallel, we are excited to present updated clinical data from our ongoing clinical trials in patients with chronic myelomonocytic leukemia (CMML) and myelofibrosis (MF). Based on these data, we are enthusiastic about our plans to implement pivotal trials, or cohorts, in these devastating malignancies."

Bavarian Nordic Announces Initiation of Clinical Trial Evaluating the Combination Therapy of CV301 and Durvalumab in Metastatic Colorectal and Pancreatic Cancers

On November 2, 2018 Bavarian Nordic A/S (OMX: BAVA, OTC: BVNRY) reported that the first patient has been dosed in a clinical study evaluating CV301, the Company’s targeted immunotherapy candidate, and durvalumab, AstraZeneca’s PD-L1 inhibitor, in combination with maintenance chemotherapy for patients with metastatic colorectal or pancreatic cancers (Press release, Bavarian Nordic, NOV 2, 2018, View Source [SID1234530665]).

Bavarian Nordic’s CV301 targets tumor-associated antigens, CEA and MUC1, which are overexpressed on multiple solid tumors, including colorectal and pancreatic cancers. Preclinical data has shown that vaccination resulted in the induction of tumor specific T-cells that infiltrated the tumor resulting in the upregulation of PD-L1 on tumor cells. The upregulation of PD-L1 is a marker indicating the tumor is under attack from T-cells, presenting an opportunity for a greater response in patients who might otherwise not benefit from treatment with a checkpoint inhibitor alone.

CV301 is administered in an innovative manner designed to generate a potent and durable T-cell response. Patients receive an enhanced priming regimen of the highly attenuated, non-replicating vaccinia virus MVA-BN-CV301 in 4 different injection sites on days 1 and 29, followed by boosters of the recombinant fowlpox virus FPV-CV301 at tapering intervals during the course of the treatment with durvalumab and maintenance chemotherapy.

The investigator-sponsored trial is being led by Dr. Michael Pishvaian, Associate Professor in the Department of Hematology/Oncology at the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center in Washington, D.C., with material support from Bavarian Nordic and AstraZeneca. The clinical trial is being conducted at several other top cancer centers including the Mayo Clinic, Indiana University and Emory University. The trial will begin with a small lead-in study to determine the safety and tolerability of the combination, as well as the recommended Phase 2 dose of durvalumab in combination with CV301 and maintenance chemotherapy. The Phase 2 portion of the study will consist of two parallel trials, enrolling up to 26 patients with metastatic disease for each disease setting. The primary endpoint for both arms of the study will be progression-free survival (PFS) with multiple secondary endpoints, including objective response rate (ORR), overall survival (OS), and disease control rate (DCR).

"We are excited to continue demonstrating CV301’s potential in multiple cancers and combinations, particularly in a treatment setting in which checkpoint inhibition alone has yet to show significant benefit. The combination of a targeted cancer vaccine with a checkpoint inhibitor could result in a novel approach to fighting colorectal and pancreatic cancers, which are among the most difficult-to-treat malignancies to date," said Paul Chaplin, President and Chief Executive Officer of Bavarian Nordic.

About CV301
CV301 is an active immunotherapy candidate that targets two tumor-associated antigens, CEA and MUC1, long known to be overexpressed in most solid tumors. The poxvirus-based prime/boost vaccine incorporates a modified version of vaccinia (MVA-BN, a proprietary technology of Bavarian Nordic) as a priming dose, followed by multiple fowlpox boosts, and encodes the TRICOM costimulatory molecules. Preclinical data shows that antigen specific vaccination results in T cell infiltration into areas of antigen expression and upregulation of PD-L1 on antigen expressing tumor cells. The upregulation of PD-L1 is a marker indicating the tumor is under attack from T-cells, presenting an opportunity for a greater response in patients who might otherwise not benefit from treatment with a checkpoint inhibitor alone.

Tolero Pharmaceuticals to Highlight New Data Evaluating Investigational Agents Alvocidib and TP-1287 at 2018 American Society of Hematology Annual Meeting

On November 2, 2018 Tolero Pharmaceuticals, Inc., a clinical-stage company focused on developing novel therapeutics for hematological and oncological diseases, reported that new data from three abstracts on the Company’s pipeline of investigational agents will be presented at the 60th Annual Meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper), December 1-4 in San Diego, California (Press release, Tolero Pharmaceuticals, NOV 2, 2018, View Source [SID1234530690]). Among the presentations, updated data from Zella 201, an ongoing Phase 2 study evaluating the efficacy and safety of alvocidib, a potent CDK9 inhibitor, in combination with cytarabine and mitoxantrone in patients with relapsed or refractory MCL-1-dependent acute myeloid leukemia (AML) will be featured in an oral presentation. Additional data from Tolero’s pipeline will also be presented, including preclinical findings on the activity of alvocidib and decitabine, as well as preclinical data evaluating the activity of TP-1287, an oral CDK9 inhibitor, in combination with bortezomib or venetoclax for the potential treatment of multiple myeloma. Three additional abstracts on Tolero sponsored research will be presented by independent research institutions.

A bout Alvocidib
Alvocidib is an investigational small molecule inhibitor of cyclin-dependent kinase 9 (CDK9) currently being evaluated in a Phase II study, Zella 201, in patients with relapsed or refractory MCL-1 dependent acute myeloid leukemia, AML, in combination with cytarabine and mitoxantrone ( NCT02520011 ). Alvocidib is also being evaluated in Zella 101, a Phase I clinical study evaluating the maximum tolerated dose, safety and clinical activity of alvocidib in combination with (7+3) in newly diagnosed patients with AML ( NCT03298984 ), and Zella 102, a Phase 1b/2 study in patients with myelodysplastic syndromes, MDS, in combination with decitabine ( NCT03593915 ). In addition, alvocidib is being evaluated in a Phase 1 study in patients with relapsed or refractory AML in combination with venetoclax ( NCT03441555 ).

About TP-1287
TP-1287 is an investigational oral cyclin-dependent kinase 9 ( CDK9) inhibitor entering into a Phase 1 study in patients with advanced solid tumors ( NCT03604783) . TP-1287 has shown favorable oral bioavailability in preclinical models. TP-1287 is enzymatically cleaved, yielding the parent drug, alvocidib, a potent inhibitor of CDK9.

About CDK9 Inhibition and MCL-1
MCL-1 is a member of the apoptosis-regulating BCL-2 family of proteins.2 In normal function, it is essential for early embryonic development and for the survival of multiple cell lineages, including lymphocytes and hematopoietic stem cells.3 In MCL-1–dependent AML, MCL-1 inhibits apoptosis and sustains the survival of leukemic blasts, which may lead to relapse or resistance to treatment.2,4 The expression of MCL-1 in leukemic blasts is regulated by cyclin-dependent kinase 9 (CDK9).5,6 Because of the short half-life of MCL-1 (2-4 hours), the effects of targeting upstream pathways are expected to reduce MCL-1 levels rapidly.5 Inhibition of CDK9 has been shown to block MCL-1 transcription, resulting in the rapid downregulation of MCL-1 protein, thus restoring the normal apoptotic regulation.2
