FDA Grants Third Orphan Drug Designation for OS2966

By | news

STAMFORD, CONNECTICUT, January 10, 2023.

Research at Children’s Hospital Los Angeles has resulted in a novel therapeutic receiving orphan drug status from the Food and Drug Administration (FDA) for the treatment of acute myeloid leukemia (AML)—an aggressive cancer with poor survival rates.

The study, led by Yong-Mi Kim, MD, PhD, MPH, in the Cancer and Blood Disease Institute, found that the investigational drug—combined with chemotherapy—prolonged survival in preclinical models of AML.

Based on that data from CHLA, the FDA granted OncoSynergy Inc. orphan drug designation for the compound, OS2966, a first-in-class monoclonal antibody that targets a protein called integrin beta-1. The designation provides incentives to advance the development of new therapies for conditions affecting fewer than 200,000 people in the U.S.

Dr. Kim’s team presented the findings Dec. 12 at the American Society of Hematology Annual Meeting in New Orleans.

“These encouraging results bring us closer to a potential clinical trial in patients,” she says. “That’s important because there is a dire need for new treatments in AML.”

‘Unsticking’ cancer cells

Like other leukemias, AML is a cancer of the blood and bone marrow. But while acute lymphoblastic leukemia (ALL) now has a near-90% cure rate in children, AML’s survival rates are much lower. In patients under age 20, five-year survival is 69%; that number plummets to just 27% for those 20 or older.

One contributing factor to that lower survival: a lack of new therapies. “We have had many new drugs come forward for ALL. But in AML, we have been using the same drugs for the past 50 to 60 years,” Dr. Kim explains. “Although the FDA has approved a few new therapies recently, the majority of those only target specific sub-groups of AML. They are not for all patients.”

That need for new and more effective treatments is what drove Dr. Kim to expand her research to include AML. The team, which has long studied drug resistance in ALL, began investigating whether similar factors could be making AML more resistant to chemotherapy.

A major focus of the group’s research involves proteins called integrins. Integrins are located on the surface of cells and act like glue, enabling cells to “stick” in certain spots. Each of these proteins has two units: an alpha unit and a beta unit.

Dr. Kim’s lab previously discovered that both integrin alpha 4 and integrin alpha 6 help leukemia cells adhere to the bone marrow—a place where they are shielded from chemotherapy.

“It’s a glue in the wrong spot,” Dr. Kim explains. “We don’t want the cancer cells glued in the bone marrow, where they’re sheltered and not vulnerable to chemotherapy.”

New findings

Based on those earlier discoveries, the team sought a way to downregulate, or “turn off,” those integrins in AML, with the goal of dislodging cancer cells from their safe haven in the bone marrow.

The investigators—which included first author Heather Ogana in Dr. Kim’s lab—chose to target integrin beta-1 because it is a partner to both of the alpha units already shown to play a key role in leukemia drug resistance. To test their hypothesis, the researchers used CRISPR-Cas9 gene editing tools to delete the gene that encodes integrin beta-1.

“We found that knocking out integrin beta-1 also decreased expression of several alpha units,” Dr. Kim says. “That supported our idea that integrin beta-1 was a good potential target. We could target one molecule but impact many others at the same time.”

The team then tested the OS2966 antibody to try to block integrin beta-1 in preclinical mouse models of AML. The study showed that combining OS2966 with chemotherapy significantly prolonged survival in these models. In addition, the antibody made AML cells more sensitive to chemotherapy.

“We think the blocking of integrin beta-1 may be helpful in two ways,” Dr. Kim says. “It could physically unstick the cells, potentially drawing them out from hiding. But we also believe that the gluing of AML cells to their microenvironment may give off intracellular signaling that is critical for their survival. When we unstick them, we may be disrupting this signaling.”

Importantly, Dr. Kim’s studies used AML samples derived from patients. “Using patient samples, in addition to AML cell lines, is key to making these preclinical studies more realistic,” she explains. “That’s critical for future success.”

Aiming for a clinical trial

The goal now is to test OS2966 in a clinical trial for both adults and children with AML. Dr. Kim is working on preliminary plans for such a trial with Deepa Bhojwani, MD, Director of the Leukemia and Lymphoma Program at CHLA, and Marina Konopleva, MD, PhD, of Albert Einstein College of Medicine in New York.

Meanwhile, her team is also investigating the underlying signaling mechanisms behind integrin beta-1 and to determine whether this pathway is relevant for all types of AML. “So far it looks promising that this could apply to different AML patients, but more study is needed before we move to a trial,” she says.

OS2966 is under development by OncoSynergy, led by CEO Anne-Marie Carbonell, MD. It is currently in a phase 1 clinical trial for recurrent glioblastoma, a difficult-to-treat brain cancer.

Dr. Kim adds that the orphan drug designation is an important milestone to support the drug’s ongoing development. “We need more therapeutic options in AML,” she says. “My hope is that this research can help pave the way for new treatments to improve the outcomes for patients with this cancer.”

OncoSynergy Announces First Patient Treated in First-in-Human Clinical Trial of OS2966 in Recurrent Glioblastoma

By | news

STAMFORD, CONNECTICUT, March 9, 2021.

OncoSynergy, Inc., a physician-founded oncology company committed to advancing therapeutics to address dire unmet medical needs, announced today that the first patient was treated in the Company’s First-in-Human Phase 1 clinical trial evaluating OS2966 for the treatment of recurrent glioblastoma at Moffitt Cancer Center in Tampa, Florida.  OS2966 is a first-in-class immunotherapy, and the first ever anti-CD29 (beta 1 integrin) therapeutic to reach human trials.

“Glioblastoma is a devastating brain cancer with few treatment options.  Its invasive growth pattern, propensity for rapid treatment resistance, and the presence of the blood-brain-barrier (BBB) preventing many therapeutics from reaching the site of disease, makes successful treatment of glioblastoma one of the biggest challenges facing oncologists and neurosurgeons,” said OncoSynergy Co-Founder and Chief Executive Officer, Anne-Marie Carbonell, MD.  “After a decade developing and demonstrating the pre-clinical potential of OS2966 in the most difficult to treat cancers, we are thrilled to have treated our first patient in a study specifically designed to overcome these challenges.”

OS2966 is a monoclonal antibody blocking CD29, a critical cell surface receptor governing multiple fundamental biological processes driving cancer growth, invasiveness, and resistance.  In OncoSynergy’s First-in-Human Phase 1 trial, OS2966 is delivered directly to the patient’s brain tumor by convection-enhanced delivery (CED), a minimally invasive technique used to bypass the BBB.  As CED involves placement of one or more catheters, OncoSynergy has partnered with Infuseon Therapeutics, a Cleveland Clinic spinout company and is utilizing Infuseon’s Cleveland Multiport Catheter to deliver OS2966.

Patients enrolled in the study must have recurrence or progression of their disease which requires tumor resection.  Incorporating tumor resection into the trial design allows for acquisition of therapeutic-infused tumor tissue enabling researchers to perform critical studies that provide additional near real-time information on how the drug performs as well as inform dosing.

“Surgical removal of a glioblastoma tumor alone is not curative because tumor cells infiltrating into the surrounding brain cannot be safely removed.  The fact that nearly all therapeutics cannot cross the blood-brain-barrier to get to those residual tumor cells means that there is an opportunity for neurosurgeons to become more involved in the therapeutic development process,” said Michael Vogelbaum, MD, PhD, Program Leader of Neuro-Oncology and Chief of Neurosurgery at Moffitt Cancer Center. Dr. Vogelbaum continued,  “Trials that consider the importance of successful delivery of a therapeutic, like OncoSynergy’s OS2966, to treat glioblastoma will provide an advantage to improving patient outcomes.”  Dr. Vogelbaum is also the Chief Medical Officer of Infuseon Therapeutics and inventor of the Cleveland Multiport Catheter™.  His role as the Primary Investigator of OncoSynergy’s trial is addressed under a conflict-of-interest management plan approved by Moffitt Cancer Center.

OncoSynergy Launches Phase I Trial for Patients With Recurrent Glioblastoma

By | news

STAMFORD, CONNECTICUT, November 17, 2020.

OncoSynergy, a patient-focused biotech startup founded by physicians trained in neurosurgery has opened enrollment in their phase 1 trial which will study OS2966, a novel therapeutic antibody, for treatment of glioblastoma.  The trial will take place at Moffitt Cancer Center in Tampa, Florida under the leadership of Michael Vogelbaum, MD, PhD.

OS2966 inhibits Beta1 integrin (CD29), a critical receptor responsible for integrating cancer promoting signals and driving cancer growth and spread.  Studies have demonstrated that resistance to anti-angiogenic therapy (i.e., bevacizumab) is associated with increased expression of Beta1 integrin.  OncoSynergy studied OS2966 in animal models implanted with patient tumor samples that had become resistant to treatment with bevacizumab.  These studies revealed that OS2966 prevented the ability of bevacizumab-resistant tumor cells to invade the surrounding brain and resulted in significant tumor cell death (Carbonell et al, 2013).

Despite advancement of several new promising cancer treatments, successful treatment of glioblastoma has been limited by the presence of the brain’s protective blood brain barrier and the invasive nature of glioblastoma.  To combat these obstacles, a technique called convection-enhanced delivery (CED) will be utilized to deliver OS2966 directly to the brain tumor and surrounding tumor-infiltrated brain.

The primary goal of this phase 1 study is to determine the safety and tolerability of OS2966 when delivered directly to the brain.  That said, given pre-clinical data demonstrating OS2966’s ability to address therapy resistant tumors and a delivery technique designed to overcome obstacles specific to glioblastoma, the ultimate hope is to improve outcomes for patients suffering from this formidable disease.

OncoSynergy and Infuseon Therapeutics Partner to Combat Glioblastoma

By | news

SAN FRANCISCO, California, June 20, 2017.

Infuseon Therapeutics and OncoSynergy have entered into a strategic alliance to test an investigational glioblastoma therapeutic, OS2966, in combination with a novel delivery device, the Cleveland Multiport CatheterTM. Glioblastoma is the most common and malignant primary brain tumor. Despite a median survival of merely 12 months, there have been only four FDA approved therapies and no improvement in overall survival in nearly three decades. This unmet need is driven in part by the inability of most chemotherapies and particularly biologics to penetrate the blood-brain-barrier.

Infuseon Therapeutics’ unique therapy delivery device, the Cleveland Multiport CatheterTM (CMC), a multiport convection-enhanced delivery catheter, was designed by neurosurgeon Michael Vogelbaum, MD, PhD, from Cleveland Clinic’s Brain Tumor and NeuroOncology Center, to more effectively deliver life-saving drugs to patients at the site of their disease. The reliability of the CMC as a loco-regional delivery device has been validated in pilot clinical trials involving delivery of a chemotherapy along with an MRI visible tracer in patients with recurrent high grade gliomas.

OncoSynergy is a UCSF spinout headquartered at Johnson & Johnson Innovation, JLABS (JLABS) in South San Francisco. JLABS @ SSF is a 30,000 square-foot life science innovation incubator, located in South San Francisco. The labs provide a flexible environment for start-up companies pursuing new technologies and research platforms to advance medical care. Through a “no strings attached” model, Johnson & Johnson Innovation does not take an equity stake in the companies occupying JLABS and the companies are free to develop products – either on their own, or by initiating a separate external partnership with Johnson & Johnson Innovation or any other company. OncoSynergy’s  first-in-class humanized and de-immunized monoclonal pan-CD29 antibody, OS2966, has demonstrated dramatic efficacy in multiple models of highly aggressive and metastatic solid cancers. Based on these data, the FDA has granted two Orphan Drug Designations for OS2966 including in the treatment of glioblastoma.

“We are pleased to join forces with Infuseon Therapeutics to tackle the complex biology of glioblastoma,” commented Anne-Marie Carbonell, MD, Vice President of Clinical Development at OncoSynergy. “The innovative combination of OS2966 and the CMC device seeks to address a huge unmet need and potentially change the way we treat patients suffering from malignant brain tumors.”

The collaboration aims to establish proof of concept that OS2966 can be successfully delivered directly to the brain with the CMC device as an impetus for a Phase I trial for the treatment of glioblastoma.

“Infuseon’s Cleveland Multiport Catheter was designed specifically to deliver therapeutics directly to the site of disease,” said Michael Vogelbaum, MD, PhD, co-Founder and Chief Medical Officer of Infuseon Therapeutics. “We are excited to pursue a potentially novel therapeutic approach to this difficult disease.”
