"Patients with AML who are resistant to or progressed following treatment with the BCL-2 inhibitor venetoclax in combination with an HMA have limited treatment options, and it has been well established in the literature that a key potential mechanism of resistance to BCL-2 targeted therapy is the switch to a dependence on MCL-1," said David J. Bearss, Ph.D., Chief Executive Officer of Tolero Pharmaceuticals, Inc. "The initiation of this study marks an important step toward understanding the potential of alvocidib as a monotherapy or in combination with low-dose cytarabine for these patients. We believe that patients whose cancers have progressed following treatment with venetoclax may be sensitive to alvocidib and this trial will help us to better understand this hypothesis."

The primary objective of the Phase 2 study is to determine the rate of combined complete remission (CR) and CR with incomplete hematological recovery (CRi), of alvocidib and alvocidib in combination with low-dose cytarabine in patients with AML. Secondary objectives include establishing the recommended treatment regimen for the second part of the study and evaluating the median overall survival (mOS) and CR rate. Additional secondary outcome measures include evaluating event-free survival (EFS), duration of composite CR (CRc), safety and tolerability of the regimen and mortality.

In the first part of the study, patients who are refractory to or have relapsed on venetoclax in combination with an HMA will be randomized into two arms. In Arm 1 of the study, patients will receive combination therapy of alvocidib and low-dose cytarabine. In Arm 2 of the study, patients will receive alvocidib monotherapy. In the second part of the study, patients will receive the regimen based on the outcome of the first part.

The trial is being conducted at sites in the United States. Additional information on this trial, including comprehensive inclusion and exclusion criteria, can be accessed at www.ClinicalTrials.gov (NCT03969420).

About Alvocidib
Alvocidib is an investigational small molecule inhibitor of cyclin-dependent kinase 9 (CDK9) currently being evaluated in the Phase 2 studies, Zella 202 in patients with acute myeloid leukemia (AML) who have either relapsed from or are refractory to venetoclax in combination with azacytidine or decitabine (NCT03969420) and Zella 201 in patients with relapsed or refractory MCL-1 dependent AML, in combination with cytarabine and mitoxantrone (NCT02520011). Alvocidib is also being evaluated in Zella 101, a Phase 1 clinical study evaluating the maximum tolerated dose, safety and clinical activity of alvocidib in combination with cytarabine and daunorubicin (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 CDK9 Inhibition and MCL-1
MCL-1 is a member of the apoptosis-regulating BCL-2 family of proteins.1 In normal function, it is essential for early embryonic development and for the survival of multiple cell lineages, including lymphocytes and hematopoietic stem cells.2 MCL-1 inhibits apoptosis and sustains the survival of leukemic blasts, which may lead to relapse or resistance to treatment.1,3 The expression of MCL-1 in leukemic blasts is regulated by cyclin-dependent kinase 9 (CDK9).4,5 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.4 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.1

On January 15, 2020 Crescendo Biologics Ltd (Crescendo), the drug developer of novel, targeted, T cell enhancing therapeutics, reported the publication of a paper that demonstrates greater tissue penetration and in vivo efficacy of Humabody VH therapeutics compared to conventional antibody formats, in the scientific journal Cancer Research a journal of the American Association for Cancer Research (AACR) (Free AACR Whitepaper) (Press release, Crescendo Biologics, JAN 15, 2020, View Source [SID1234553230]).

The study run by Dr Greg M. Thurber at the University of Michigan demonstrates that the level of tissue penetration by Humabodies plays a major role in therapeutic efficacy and illustrates the benefits of using an albumin-binding domain to extend serum circulation time.

Humabodies are small, in vivo matured human VH domain building blocks that can be easily assembled into multifunctional molecules. They can be configured for optimal target engagement in ways which can be challenging for regular antibody formats. Dr Thurber’s results confirm that the smaller size and specifically tailored binding configuration achievable with Humabody molecules can result in improved penetration into the tumour microenvironment and a greater cancer-killing effect using a preclinical in vivo model of prostate cancer.

Dr Greg M. Thurber, an associate professor of chemical engineering and biomedical engineering at the University of Michigan, said:

"The tissue and cellular distribution of biologics is an important but understudied area in drug development. In collaboration with Crescendo, we demonstrated that the distribution of these drugs within the tumor was as significant as the total tumor dose in determining response. Importantly, this work shows how antibody engineering strategies can be used to design therapeutics with improved distribution to maximize efficacy."

Dr James Legg, SVP R&D at Crescendo Biologics, noted that:

"We’re delighted to be working with Greg Thurber’s team at the University of Michigan; they have developed a deep mechanistic understanding and expertise in the in vivo distribution of therapeutic agents. We look forward to continuing our collaboration."

On January 15, 2020 The HealthWell Foundation, an independent non-profit that provides a financial lifeline for inadequately insured Americans, reported that it has opened a new fund to provide copayment and premium assistance to Medicare patients living with small cell lung cancer (SCLC) (Press release, HealthWell Foundation, JAN 15, 2020, View Source [SID1234553247]).

About Small Cell Lung Cancer (SCLC)

SCLC, a type of neuroendocrine tumor, typically starts in the bronchi, the major airways in the center of the chest that lead to the lungs. SCLC is an aggressive cancer that grows and spreads rapidly, according to LUNGevity, a leading national lung cancer organization. SCLC represents approximately 15 percent of all lung cancers and about two-thirds of those diagnosed have extensive-stage disease, cancer that has metastasized or spread to other lymph nodes or organs, at the time of diagnosis. Treatment options vary depending on the stage of the disease and typically include one or more types of therapy, such as surgery, chemotherapy, radiation therapy or palliative care.

"A lung cancer diagnosis can leave patients feeling overwhelmed and worried about next steps in managing their condition. Many patients, especially those on Medicare, are concerned about their treatment options and whether they will be able to afford the proper care," said Katie Brown, OPN-CG, Vice President Support and Survivorship Programs at LUNGevity. "Eliminating as much stress as possible is critical to overall wellbeing and positive outcomes when navigating a lung cancer diagnosis. We applaud the HealthWell Foundation for recognizing the financial challenges people living with small cell lung cancer face and for assisting this patient community in accessing critical medical treatments without the stress of having to worry about covering the cost of their treatments."

"A diagnosis of small cell lung cancer can be devastating for the patient and their family. Treatment options often consist of chemotherapy and radiation, high-cost therapies that can create financial hardship and additional stress, especially for those on Medicare," stated HealthWell Foundation President, Krista Zodet. "We are honored that our dedicated donors understand the underlying challenges SCLC patients and their families face in accessing and affording treatment. We are excited to be able to assist Medicare patients living with SCLC with their out-of-pocket treatment costs and to be able to relieve some of the financial burden associated with those costs."
