Idera Pharmaceuticals Presents New Intratumoral IMO-2125 Preclinical Data at CRI-CIMT-EATI-AACR Inaugural International Cancer Immunotherapy Conference

On September 16, 2015 Idera Pharmaceuticals, Inc. (NASDAQ:IDRA), a clinical-stage biopharmaceutical company developing Toll-like receptor (TLR) and RNA therapeutics for patients with cancer and rare diseases, reported new preclinical data that showed cancer immunotherapy with intratumoral injections of IMO-2125 alone and in combination with ipilimumab demonstrated potent and systemic anti-tumor activity in preclinical cancer models (Press release, Idera Pharmaceuticals, SEP 16, 2015, View Source;p=RssLanding&cat=news&id=2088264 [SID:1234507478]). IMO-2125 is a synthetic oligonucleotide-based agonist of Toll-like receptor 9 discovered and developed by Idera. Ipilimumab is a checkpoint inhibitor targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). Additionally, Idera presented preclinical data which demonstrated that IMO-2125 induces a systemic antitumor immune response with the potential to sensitize the tumor microenvironment for combination with various checkpoint inhibitors. These data are being presented at the CRI-CIMT-EATI-AACR Inaugural International Cancer Immunotherapy Conference (CIMT) (Free CIMT Whitepaper) in New York City, beginning today.

"The body of preclinical data that we have assembled further illustrates the potential of intratumoral IMO-2125 to play an important role in the emerging field of cancer immunotherapy," stated Sudhir Agrawal, D.Phil., President of Research at Idera Pharmaceuticals. "We are looking forward to advancing this approach into clinical development with our first study and exploring additional clinical studies with intratumoral IMO-2125 in other tumor types and with other checkpoint inhibitor combination regimens."

In the presentation, entitled "Intratumoral administration of IMO-2125, a novel TLR9 agonist, modulates the tumor microenvironment and exerts systemic antitumor activity alone and in combination with an anti-CTLA4 monoclonal antibody (mAb)," Idera scientists presented data suggesting that intratumoral IMO-2125 monotherapy led to dose-dependent decreases in treated and distant tumor volume, an increase in infiltrating CD8+ T cells and specific cytotoxic T cell responses against tumor antigens. Combination of intratumoral IMO-2125 and an anti-CTLA4 mAb showed improved inhibition of tumor growth, regression of systemic lung metastases and infiltration of TILs versus monotherapy with either agent. Collectively, these data demonstrate the potent antitumor activity of IMO-2125, a novel immunostimulatory TLR9 agonist, alone and in combination with a checkpoint inhibitor.

Idera expects to initiate the first clinical study of intratumoral IMO-2125 in combination with ipilimumab in patients with metastatic melanoma in the fourth quarter of this year as part of the previously announced clinical research alliance with MD Anderson Cancer Center.

In the presentation, entitled "Modulation of checkpoint expression in tumor microenvironment by intratumoral administration of a novel TLR9 agonist: Rationale for combination therapy," Idera scientists presented data suggesting that intratumoral IMO-2125 treatment led to antitumor activity in preclinical tumor models of lymphoma, colon carcinoma and melanoma. Specifically, intratumoral IMO-2125 treatment resulted in changes in the tumor microenvironment in both treated and distant tumors, as demonstrated by modulation of immune checkpoint gene expression. These data showed that intratumoral IMO-2125 has the potential to sensitize the tumor microenvironment for combination with various checkpoint inhibitors.

These presentations are both currently available on Idera’s website at View Source

Additionally, Idera announced that pre-clinical data relating to the combination of intratumoral IMO-2125 and an anti-PD-1 mAb in a murine colon carcinoma model will be presented at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) in Boston from November 5-9th.

About Toll-like Receptors and Idera’s Immuno-Oncology Research Program

Toll-like receptors (TLRs) are believed to play a central role in the innate immune system, the body’s first line of defense against invading pathogens, as well as damaged or dysfunctional cells including cancer cells. The innate immune system is also involved in activating the adaptive immune system, which marshals highly specific immune responses to target pathogens or tissue. Cancer cells may exploit regulatory checkpoint pathways to avoid being recognized by the immune system, thereby shielding the tumor from immune attack. Checkpoint inhibitors such as agents targeting CTLA4 or programmed cell death protein 1 (PD1) are designed to enable the immune system to recognize tumor cells. In this setting, intratumoral TLR9 agonist administration may increase the tumor-infiltrating lymphocytes (TILs); and potentiate anti-cancer activity of checkpoint inhibitors in the injected tumor as well as systemically.

Idera’s TLR9 agonists, IMO-2125 and IMO-2055, have been created using the company’s proprietary chemistry-based discovery platform. IMO-2125 has been shown to activate dendritic cells and induce interferon. Idera selected IMO-2125 to advance into clinical development in combination with checkpoint inhibitors based on this immunological profile. In previously completed clinical trials, subcutaneous administration of IMO-2125 was generally well tolerated in about 80 patients with hepatitis C. Idera has conducted further preclinical research evaluating the potential of IMO-2125 to enhance the anti-tumor activity of other checkpoint inhibitors in cancer immunotherapy with data from these studies to be presented at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) in November in Boston.

Bristol-Myers Squibb’s Opdivo (nivolumab) Receives Breakthrough Therapy Designation from U.S. Food and Drug Administration for Advanced Renal Cell Carcinoma

On September 16, 2015 Bristol-Myers Squibb Company (NYSE:BMY) reported that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to Opdivo for the potential indication of advanced or metastatic renal cell carcinoma (RCC) (Press release, Bristol-Myers Squibb, SEP 16, 2015, View Source [SID:1234507477]). The Breakthrough Therapy designation is an FDA program intended to expedite the development and review of medicines with early signals of potential clinical benefit in serious diseases to help ensure patients have access to new therapies as soon as possible.

This designation is based on results of CheckMate -025, a Phase 3 study that evaluated the survival of patients with previously treated advanced or metastatic clear-cell RCC versus everolimus, a current standard of care for patients with previously treated kidney cancer. The trial was stopped early in July 2015 because an assessment conducted by the independent Data Monitoring Committee (DMC) concluded that the study met its primary endpoint of overall survival, demonstrating superior overall survival in patients receiving Opdivo compared to the control arm. Bristol-Myers Squibb will be presenting further data from this study at the upcoming 2015 European Cancer Congress (ECC), and looks forward to submitting these data to regulatory authorities this year.

Michael Giordano, senior vice president, head of Development, Oncology commented, "Results from CheckMate -025 mark the third tumor in which Opdivo has shown an overall survival benefit in a Phase 3 trial. The Breakthrough Therapy Designation in advanced renal cell carcinoma is a clear signal of the need for additional treatment approaches for RCC and reflects part of our broad commitment to Immuno-Oncology research that may address many types of advanced cancers."

According to the FDA, the criteria for Breakthrough Therapy Designation requires preliminary clinical evidence that demonstrates the medicine may have substantial improvement on at least one clinically significant endpoint over available therapy. This is the fourth Breakthrough Therapy Designation granted for Opdivo by the FDA, with previous indications including patients with Hodgkin lymphoma after failure of autologous stem cell transplant and brentuximab, previously treated advanced melanoma, and previously treated non-squamous non-small cell lung cancer.

About Renal Cell Carcinoma

Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults, accounting for more than 100,000 deaths worldwide each year. Clear-cell RCC is the most prevalent type of RCC and constitutes 80 percent to 90 percent of all cases. RCC is approximately twice as common in men as it is in women, with the highest rates of the disease found in North America and Europe. Globally, the five-year survival rate for those diagnosed with metastatic, or advanced kidney cancer, is 12.1 percent.

About Opdivo

Bristol-Myers Squibb has a broad, global development program to study Opdivo in multiple tumor types consisting of more than 50 trials – as monotherapy or in combination with other therapies – in which more than 8,000 patients have been enrolled worldwide.

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that has received approval from the U.S. Food and Drug Administration (FDA) as a monotherapy in two cancer indications. Opdivo became the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world on July 4, 2014 when Ono Pharmaceutical Co. announced that it received manufacturing and marketing approval in Japan for the treatment of patients with unresectable melanoma. In the U.S., the FDA granted its first approval for Opdivo for the treatment of patients with unresectable or metastatic melanoma and disease progression following Yervoy (ipilimumab) and, if BRAF V600 mutation positive, a BRAF inhibitor. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. On March 4, 2015, Opdivo received its second FDA approval for the treatment of patients with metastatic squamous non-small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy. On July 20, the European Commission approved Nivolumab BMS for the treatment of locally advanced or metastatic squamous non-small cell lung cancer after prior chemotherapy.

The collaboration includes molecular engineering by Xencor and the preclinical development of bispecific molecules for five programs proposed by Amgen, leveraging XmAb bispecific Fc domains to make half-life extended T cell engagers and dual targeting bispecific antibodies. The agreement also includes a preclinical bispecific T cell engager program directed at CD38 and CD3 for multiple myeloma.

Amgen will be fully responsible for preclinical and clinical development and commercialization worldwide. Under the terms of the agreement, Xencor will receive a $45 million upfront payment and up to $1.7 billion in clinical, regulatory and sales milestone payments in total for the six programs. Xencor is eligible to receive mid to high single-digit royalties for candidates directed against Amgen’s targets, and high single to low double-digit royalties for Xencor’s CD38 bispecific T cell engager.

"We are pleased to be joining forces with Xencor to expand our immuno-oncology and inflammation position by leveraging Amgen’s antibodies and Xencor’s bispecific antibody platform," said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen. "We are especially excited about the T cell engaging bispecific antibody directed against CD38, which complements Amgen’s BiTE platform, while growing our hematology and oncology portfolio that includes two bispecific T cell engager antibodies, BLINCYTO (blinatumomab) and AMG 330, as well as Kyprolis (carfilzomib) for relapsed multiple myeloma."

Bispecific technologies seek to engineer monoclonal antibodies to bind two unique drug targets, as opposed to traditional antibodies designed to bind to a single antigen target. This approach represents a powerful opportunity in immuno-oncology to simultaneously engage immune cells and tumor cells to localize anti-tumor immune activity where it is needed most.

"Amgen, which has pioneered the use of bispecific antibodies, has chosen to access our XmAb bispecific technology for its robustness, long half-life, and the plug and play ease-of-development of our platform," said Bassil Dahiyat, Ph.D., president and chief executive officer of Xencor. "This opportunity expands the reach of our technology with a partner that has proven experience in bispecifics and immuno-oncology. Xencor will continue to focus on its internal programs including its immuno-oncology XmAb bispecifics, XmAb14045 in acute myeloid leukemia and XmAb13676 in B-cell malignancies, which are expected to enter clinical development in 2016."

About Xencor’s XmAb Bispecific Technology
As opposed to traditional monoclonal antibodies that target and bind to a single antigen, bispecific antibodies are designed to elicit multiple biological effects that require simultaneous binding to two different antigen targets. Xencor’s XmAb bispecific Fc domain technology is designed to maintain full-length antibody properties in a bispecific antibody, potentially enabling favorable in vivo half-life and simplified manufacturing.

Efforts at bispecific antibody design are typically frustrated by poor molecular stability, difficulties in production and short in vivo half-life. Xencor has engineered a series of Fc domain variants that spontaneously form stable, heterodimeric bispecific antibodies and that can be made and purified with standard antibody production methods. These bispecific Fc domains are used to generate a broad array of novel drug candidates in a range of molecule formats.

Xencor’s initial bispecific programs are tumor-targeted antibodies that contain both a tumor antigen binding domain and a cytotoxic T-cell binding domain (CD3 binding domain). These bispecific antibodies activate T cells at the site of the tumor for highly potent killing of malignant cells. The XmAb Fc domain format allows Xencor to tune the potency of the T-cell killing, potentially improving the tolerability of tumor immunotherapy. Xencor plans to begin clinical testing for two internal programs, XmAb14045 and XmAb13676, in 2016.
