The response rate of the DLBCL cohort exceeded pre-specified criteria. As a result, the company will expand the cohort up to an additional 30 patients. This group represents the second of four cohorts to be expanded in this Phase 2 study. Previously the company announced the expansion of the study’s multiple myeloma (MM) cohort. Additional updates on the two remaining select B-cell lymphoma cohorts will be provided when data are available.

"Relapse or refractory DLBCL is an aggressive cancer and the initial response rates from the cohort leave us optimistic in CLR 131’s potential to have a positive impact on patients with life-threatening hematologic cancers. We continue to see clinical benefit using CLR 131 across a range of cancer types and we look forward to providing future data updates on this indication and others," stated James Caruso, president and chief executive officer of Cellectar Biosciences.

About the Phase 2 Study of CLR 131

The Phase 2 study is being conducted in approximately 10 leading cancer centers in the United States for patients with relapsed or refractory B-cell hematologic cancers. The hematologic cancers being studied include (MM, chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), lymphoplasmacytic lymphoma (LPL), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), and potentially diffuse large B-cell lymphoma (DLBCL).

The study’s primary endpoint is clinical benefit response (CBR), with additional endpoints of progression free survival (PFS), median overall survival (OS) and other markers of efficacy following a single 25.0 mCi/m2 dose of CLR 131, with the option for a second 25.0 mCi/m2 dose approximately 75-180 days later.

In addition to the CLR 131 infusion(s), MM patients will receive 40 mg oral dexamethasone weekly for up to 12 weeks. Efficacy responses will be determined by the latest International Multiple Myeloma Working Group criteria. Efficacy for all lymphoma patients will be determined according to Lugano criteria. Cellectar has been awarded approximately $2 million in a non-dilutive grant from the National Cancer Institute to help fund the trial. More information about the trial, including eligibility requirements, can be found at www.clinicaltrials.gov, reference NCT02952508.

About Diffuse Large B-Cell Lymphoma

According to the Lymphoma Research Foundation, diffuse large B-cell lymphoma (DLBCL) is an aggressive form of non-Hodgkin’s lymphoma (NHL), accounting for about 30 percent of newly diagnosed cases of NHL in the United States.

The American Cancer Society’s most recent estimates for NHL for 2018 project approximately 74,680 people (41,730 males and 32,950 females) will be diagnosed with NHL including both adults and children. They estimate that approximately 19,910 people will die from this cancer (11,510 males and 8,400 females).

DLBCL occurs in both men and women, although it is slightly more common in men. Although DLBCL can occur in childhood, its incidence generally increases with age, and roughly half of patients are over the age of 60.

DLBCL is an aggressive (fast-growing) lymphoma that can arise in lymph nodes or outside of the lymphatic system, in the gastrointestinal tract, testes, thyroid, skin, breast, bone, or brain. Often, the first sign of DLBCL is a painless, rapid swelling in the neck, underarms, or groin that is caused by enlarged lymph nodes. For some patients, the swelling may be painful. Other symptoms may include night sweats, fever, and unexplained weight loss. Patients may notice fatigue, loss of appetite, shortness of breath, or pain.

About Phospholipid Drug Conjugates (PDCs)

Cellectar’s product candidates are built upon a patented delivery and retention platform that utilizes optimized PDCs to target cancer cells. The PDC platform selectively delivers diverse oncologic payloads to cancerous cells and cancer stem cells, including hematologic cancers and solid tumors. This selective delivery allows the payloads’ therapeutic window to be modified, which may maintain or enhance drug potency while reducing the number and severity of adverse events. This platform takes advantage of a metabolic pathway utilized by all tumor cell types in all cell cycle stages. Compared with other targeted delivery platforms, the PDC platform’s mechanism of entry does not rely upon specific cell surface epitopes or antigens. In addition, PDCs can be conjugated to molecules in numerous ways, thereby increasing the types of molecules selectively delivered. Cellectar believes the PDC platform holds potential for the discovery and development of the next generation of cancer-targeting agents.

About CLR 131

CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company’s proprietary phospholipid ether (PLE) and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131, is in a Phase 2 clinical study in relapsed or refractory (R/R) MM and a range of B-cell malignancies and a Phase 1 clinical study in patients with (R/R) MM exploring fractionated dosing. In 2018 the company plans to initiate a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma, and a second Phase 1 study in combination with external beam radiation for head and neck cancer.

On June 28, 2018 Corvus Pharmaceuticals, Inc. (NASDAQ:CRVS), a clinical-stage biopharmaceutical company focused on the development and commercialization of precisely targeted oncology therapies, reported publication of results of preclinical studies of CPI-444 conducted by researchers at Johns Hopkins University School of Medicine (Press release, Corvus Pharmaceuticals, JUN 28, 2018, View Source;p=RssLanding&cat=news&id=2356398 [SID1234527496]). The data showed that CPI-444 administered as monotherapy suppressed tumor growth and improved survival in animal tumor models, and CPI-444 administered in combination with anti-PD-1 therapy dramatically improved antitumor immune responses over either agent used alone. The results were published online this month in the journal Cancer Immunology, Immunotherapy (CII), in a publication titled "Inhibition of the adenosine A2a receptor modulates expression of T cell coinhibitory receptors and improves effector function for enhanced checkpoint blockade and ACT (adoptive cellular therapy) in murine cancer models," and can be accessed here.

CPI-444, Corvus’ lead product candidate, is a selective and potent inhibitor of the adenosine A2A receptor. It is currently being evaluated in early-stage clinical trials in patients with various solid tumors as a single agent and in combination with Genentech’s atezolizumab, an anti-PD-L1 antibody.

"These newly published studies add to the growing scientific and clinical evidence of the importance of the adenosine pathway in modulating immune responses in cancer. The results provide further evidence that the A2A receptor may serve as a crucial regulator of immune response, and confirms the potential of CPI-444 in cancer therapy," said Richard A. Miller, M.D., an oncologist and co-founder, president and chief executive officer of Corvus. "CPI-444 has been studied in more than 250 patients to date both as a monotherapy and in combination with an anti-PD-L1 antibody. To our knowledge, it is the only A2A receptor antagonist to reproducibly show anti-tumor activity as a monotherapy in preclinical and clinical studies. We are currently enrolling patients in a Phase 1/1b trial in renal cell cancer and in a Phase 1b/2 trial in non-small cell lung cancer."

Results of the preclinical studies conducted by researchers at the Sidney Kimmel Comprehensive Cancer Research Center and Bloomberg~Kimmel Institute for Cancer Immunotherapy at Johns Hopkins University School of Medicine, showed that CPI-444:

Administered as monotherapy suppressed tumor growth and improved survival in two animal models of colon tumors — CT26, which is very resistant to checkpoint blockade, and MC38.
Enhanced the efficacy of anti-PD-1 immunotherapy. The combination therapy dramatically improved tumor regression and animal survival in both the CT26 and MC38 colon tumor models. The effect was particularly marked in the CT26 tumor model, which showed a 70 percent cure rate.
Dramatically enhanced immune responses in models of tumor immunity, augmented immune memory responses to viral antigens, and enhanced adoptive cellular therapy (ACT) in an animal model of melanoma.
Suppressed the expression of multiple checkpoint pathways, including PD-1, LAG-3, TIM-3 and CTLA-4, on both CD8 positive and T reg cells (which play an important role in regulating antitumor immune responses). The most significant effects were seen in tumor-draining lymph nodes.
Increased the function of killer T cells (CD8+) in tumor infiltrating cells.
ABOUT CPI-444
CPI-444 is a small molecule, oral, checkpoint inhibitor designed to disable a tumor’s ability to subvert attack by the immune system by blocking the binding of adenosine in the tumor microenvironment to the A2A receptor. Adenosine, a metabolite of ATP (adenosine tri-phosphate), is produced within the tumor microenvironment where it may bind to the adenosine A2A receptor present on immune cells and block their activity. CD39 and CD73 are enzymes on the surface of tumor cells and immune cells. These enzymes work in concert to convert ATP to adenosine. In vitro and preclinical studies have shown that dual blockade of CD73 and the A2A receptor may be synergistic.
