On February 6, 2017 Galena Biopharma, Inc. (NASDAQ:GALE), a biopharmaceutical company committed to the development and commercialization of hematology and oncology therapeutics that address unmet medical needs, reported the results from a meeting of the Data Safety Monitoring Board (DSMB) for the two investigator-sponsored (IST) combination clinical trials with NeuVax (nelipepimut-S) plus trastuzumab (Press release, Galena Biopharma, FEB 6, 2017, View Source [SID1234517647]). The trials are being run in breast cancer patients to assess the ability of the combination of trastuzumab and the HER2 vaccine nelipepimut-S (administered with the immunoadjuvant granulocyte macrophage-colony stimulating factor) to prevent recurrence in the adjuvant setting.

In light of the early termination of the NeuVax Phase 3 PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax Treatment) trial last year, the independent DSMB performed separate futility assessments on each of the NeuVax plus trastuzumab combination trials. The DSMB reported that there are no safety concerns with either trial and neither was found to be futile.

For the Phase 2b trial in patients with low-to-intermediate HER2 expression (HER2 1+/2+), n=242 patients were evaluated, and the recommendation from the DSMB is to continue the trial with one revision to the statistical analysis plan regarding the timing of the pre-specified interim analysis. Given the lengthy duration of enrollment for the trial, the DSMB determined that the pre-specified interim efficacy analysis be moved up from 12 months to 6 months after the last patient is enrolled. Completion of enrollment is expected in the second quarter of 2017; therefore, the DSMB expects to perform the interim efficacy analysis near the end of 2017.

For the Phase 2 trial in high-risk, HER2 3+ patients, and per the trial protocol, the pre-specified interim safety analysis was also completed on n=50 patients and demonstrated that the agent is well tolerated with no increased cardiotoxicity associated with giving NeuVax in combination with trastuzumab. These findings were similar to the findings presented in October 2016 from the HER2 1+/2+ trial. The recommendation from the DSMB is to continue the HER2 3+ trial unmodified.

"The recommendations from the DSMB are very positive for NeuVax in combination with trastuzumab as there were no safety concerns and the studies were not deemed futile. Given these findings, the trials can continue per the DSMB recommendation," said Bijan Nejadnik, M.D., Executive Vice President and Chief Medical Officer. "We are also pleased that we will be able to reach the interim efficacy analysis in our Phase 2b HER2 1+/2+ trial earlier than expected with that readout now planned by the end of this year. It is important to note that these IST trials are designed with a different methodology to identify recurrences clinically and not via proactive imaging as was done in the PRESENT trial. We are grateful to our investigators running these trials and their continued dedication to breast cancer patients as they study potential new therapeutic options to prevent recurrence."

About NeuVax (nelipepimut-S)

NeuVax (nelipepimut-S) is a first-in-class, HER2-directed cancer immunotherapy under evaluation to prevent breast cancer recurrence after standard of care treatment in the adjuvant setting. NeuVax contains the immunodominant peptide derived from the extracellular domain of the HER2 protein, a well-established target for therapeutic intervention in breast carcinoma. The nelipepimut-S sequence stimulates specific CD8+ cytotoxic T lymphocytes (CTLs) following binding to specific HLA molecules on antigen presenting cells (APC). These activated specific CTLs recognize, neutralize and destroy, through cell lysis, HER2 expressing cancer cells, including occult cancer cells and micrometastatic foci. The nelipepimut-S immune response can also generate CTLs to other immunogenic peptides through inter- and intra-antigenic epitope spreading. In clinical studies, NeuVax is combined with recombinant granulocyte macrophage-colony stimulating factor (GM-CSF).

NeuVax is currently in two breast cancer studies in combination with trastuzumab (Herceptin; Genentech/Roche): a Phase 2b trial in node positive and triple negative HER2 IHC 1+/2+ (clinicaltrials.gov identifier: NCT01570036); and, a Phase 2 trial in high risk, node positive or negative HER2 IHC 3+ patients (clinicaltrials.gov identifier: NCT02297698). A Phase 2 clinical trial is also ongoing with NeuVax in patients with ductal carcinoma in situ (DCIS) (clinicaltrials.gov identifier: NCT02636582), and a Phase 2 trial is planned in patients with gastric cancer.

Initiation of pivotal Phase III trial with ATIR101
Following regulatory approval from the national authority in Canada (Health Canada), the Company is pleased to announce the initiation of its randomized, controlled, transatlantic Phase III trial with ATIR101 (CR-AIR-009). Approximately 195 patients with acute leukemia will be enrolled in total in the Phase III trial and randomized 1:1 to receive a haploidentical allogeneic HSCT using either the Kiadis Pharma approach with a single dose of ATIR101 or the post-transplant cyclophosphamide approach (also known as the Baltimore Protocol). The trial protocol has also been submitted for approval and is being evaluated by the United States FDA (Food and Drug Administration) as well as several European regulatory authorities. Following approval the trial will be rolled out to additional study centers in the United States and Europe.

CTI Clinical Trial and Consulting Services, Inc., an international clinical contract research organization, has been appointed to work with Kiadis Pharma to support the clinical part of the trial and PCT, LLC, A Caladrius Company, a leading external manufacturing partner to the cell therapy industry, will manufacture ATIR101 for the United States and Canada. The German Red Cross Blood Donor Service, Baden-Wuerttemberg-Hessen, will remain the manufacturer in Europe. All 15 study centers that participated in the Company’s Phase II trials with ATIR101 (CR-AIR-007 and CR-AIR-008) have confirmed their intention to participate in the Phase III trial (CR-AIR-009). Kiadis Pharma is actively and rapidly aligning more sites with the aim of having more than 40 sites in North America and Europe participating in the Phase III trial.

Ongoing CR-AIR-008 trial continues to confirm safety profile of ATIR101
Infusing a single dose of ATIR101 continues to be safe in the ongoing Phase II trial with ATIR101 (CR-AIR-008) which, as previously announced, is continuing to treat patients with a single dose of ATIR101 according to the clinical protocol and the recommendation of the Independent Data Monitoring Committee (IDMC). Five patients in this trial have now been treated with a single dose of ATIR101 of which three were infused more than 120 to 150 days ago. None of these patients have shown any symptoms of severe Graft-versus-Host-Disease (GVHD), with none having received any prophylactic immunosuppression.

MAA submission to EMA for ATIR101 progressing well
Following the Company’s decision to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for the use of ATIR101 in blood cancers, Kiadis Pharma confirms that the preparations for submitting the dossier are progressing well. The MAA will be based on the results from the Company’s successful single dose Phase II trial (CR-AIR-007) which confirmed that ATIR101 can be safely infused and shows statistically significant benefits on overall survival and reducing death from GVHD and infections, compared to an observational control group of patients having received a similar T-cell depleted stem cell transplant from a haploidentical family member but without the addition of ATIR101.

Kiadis Pharma has previously received an Advanced Therapy Medicinal Product (ATMP) certificate from EMA for manufacturing quality and pre-clinical data, recognizing that this data generated for ATIR101 meets the stringent standards imposed by the agency in evaluating an MAA.

Contingent on approval from EMA, Kiadis Pharma anticipates launching ATIR101 in to the European market in 2018.

Phase I/II trial with ATIR201
As previously announced, the Company’s Phase I/II clinical trial with its product ATIR201 for thalassemia (CR-BD-001) has received regulatory approval from the national authority in the United Kingdom (the MHRA, the Medicines and Healthcare products Regulatory Agency) as well as approval from the Ethics Committees of the Royal Manchester Children’s Hospital and the Birmingham Children’s Hospital. In addition, approval from the Ethics Committee of the University of Regensburg in Germany has now been received, with regulatory approval from the national authority in Germany pending. Kiadis Pharma expects the first clinical trial data to become available in the second half of 2017.

Manfred Rüdiger, PhD, Chief Executive Officer of Kiadis Pharma, commented: "I am very excited that we have initiated our pivotal Phase III trial with ATIR101. We have significant momentum now and the preparation of our MAA submission to EMA is progressing well. This work will bring our potentially life-saving treatment, which is also protected by Orphan Drug Designations in both Europe and the US, one step closer to patients with an anticipated launch in Europe in 2018."

About ATIR101
For patients suffering from blood cancers, an allogeneic hematopoietic stem cell transplantation (HSCT) is generally regarded as the most effective curative approach. During an HSCT treatment, the bone marrow, harboring the diseased cancer cells, is completely destroyed and subsequently replaced by stem cells in the graft from a healthy donor. After an HSCT treatment it usually takes the patient at least six to twelve months to recover to near-normal blood cell levels and immune cell functions. During this period, the patient is highly vulnerable to infections caused by bacteria, viruses and fungi but also to disease relapse.

ATIR101 (Allodepleted T-cell ImmunotheRapeutics) provides for a safe donor lymphocyte infusion (DLI) from a partially matched (haploidentical) family member without the risk of causing severe Graft-versus-Host-Disease (GVHD). The T-cells in ATIR101 will help fight infections and remaining tumor cells and thereby bridge the time until the immune system has fully re-grown from stem cells in the transplanted graft.

In ATIR101, T-cells that would cause GVHD are eliminated from the donor lymphocytes using Kiadis Pharma’s photodepletion technology, minimizing the risk of GVHD and eliminating the need for prophylactic immune-suppression. At the same time, ATIR101 contains potential cancer killing T-cells from the donor that could eliminate residual cancer cells and help prevent relapse of the disease, known as the Graft-versus-Leukemia (GVL) effect.

Therefore, ATIR101, administered as an adjunctive immuno-therapeutic on top of HSCT, provides the patient with functional, mature immune cells from a partially matched family donor that can fight infections and tumor cells but that do not cause GVHD. ATIR101 thus has the potential to make curative HSCT a viable option to many more patients.

The Company estimates that approximately 35% of patients who are eligible and in urgent need of HSCT will not find a matching donor in time. A partially matched (haploidentical) family donor, however, will be available to over 95% of patients.

ATIR101, consisting of donor T-cells that fight infections and residual tumor cells while not eliciting severe GVHD, is designed to result in low relapse rates and low rates of death due to infections, in the absence of severe acute GVHD.

On February 6, 2017 Cellectis (Alternext: ALCLS; Nasdaq: CLLS), a biopharmaceutical company focused on developing immunotherapies based on gene edited CAR T-cells (UCART), reported it has received an Investigational New Drug (IND) approval from the U.S. Food and Drug Administration (FDA) to conduct Phase 1 clinical trials with UCART123, the Company’s most advanced, wholly owned TALEN gene-edited product candidate, in patients with acute myeloid leukemia (AML) and blastic plasmacytoid dendritic cell neoplasm (BPDCN) (Press release, Cellectis, FEB 6, 2017, View Source [SID1234517650]). This marks the first allogeneic, "off-the-shelf" gene-edited CAR T-cell product candidate that the FDA has approved for clinical trials. Cellectis intends to initiate Phase 1 trials in the first half of 2017.

UCART123 is a gene-edited T-cell investigational drug that targets CD123, an antigen expressed at the surface of leukemic cells in AML, tumoral cells in BPDCN. The clinical research for AML will be led, at Weill Cornell, by principal investigator Dr. Gail J. Roboz, Director of the Clinical and Translational Leukemia Programs and Professor of Medicine. The UCART123 clinical program for BPDCN will be led, at the MD Anderson Cancer Center, by Dr. Naveen Pemmaraju, MD, Assistant Professor, and Professor Hagop Kantarjian, MD, Department Chair, Department of Leukemia, Division of Cancer Medicine.

AML is a devastating clonal hematopoietic stem cell neoplasm that is characterized by uncontrolled proliferation and accumulation of leukemic blasts in bone marrow, peripheral blood and, occasionally, in other tissues. These cells disrupt normal hematopoiesis and rapidly cause bone marrow failure and death. In the U.S. alone, there are an estimated 19,950 new AML cases per year, with 10,430 estimated deaths per year.

BPDCN is a very rare and aggressive hematological malignancy that is derived from plasmacytoid dendritic cell precursors. BPDCN is a disease of bone marrow and blood cells but also often affects skin and lymph nodes.

"The FDA’s approval of Cellectis’ UCART123 – the first "off-the-shelf" CAR T-cell product candidate to enter clinical trials in the U.S. – is a major milestone not only for the Company but also for the medical community, global biotech and pharmaceutical industries at large," said Dr. Loan Hoang-Sayag, Cellectis Chief Medical Officer. "Cellectis’ allogeneic UCART products have the potential to create an important shift with regard to availability, and cost-effectiveness, to make these therapies widely accessible to patient population across the world."

"After the National Institutes of Health’s Recombinant DNA Advisory Committee (RAC)’s unanimous approval of two Phase 1 study protocols for Cellectis’ UCART123 in December 2016, the FDA’s approval of Cellectis’ IND is a new major regulatory milestone achieved, for having UCART123 proceed into clinical development and reaching cancer patients in need," added Stephan Reynier, Chief Regulatory and Compliance Officer, Cellectis.

"Early detection of ocular melanoma, combined with the administration of AU-011 as a potential vision-sparing therapy, could transform the treatment of patients with this devastating disease," said Brian Marr, M.D., Director of the Ophthalmic Oncology Service at Columbia University Medical Center. Dr. Marr is the principal investigator for the AU-011 clinical trial and also is a member of Aura’s Clinical Advisory Board.

"Receiving IND clearance to enter the clinic for AU-011 is an important step in the development pathway for this novel class of drugs, and I’m thankful to our team of dedicated employees, as well as to our distinguished scientific and clinical advisors, for their contributions that have propelled us to this point," said Elisabet de los Pinos, Ph.D., founder and CEO of Aura. "With the advancement of AU-011, we are opening the door for innovation in a completely new therapeutic area where there are no FDA drugs approved today. Our hope is that AU-011 could be used to treat small primary melanomas early, with the potential to eliminate the tumor and preserve vision for patients."

The Phase 1b open-label, single ascending dose clinical trial currently enrolling is designed to evaluate the safety, immunogenicity and preliminary efficacy of two dose levels of AU-011 for the treatment of small-to-medium primary OM. Screening procedures for eligible patients are underway at five clinical trial sites across the country. For more information, visit www.clinicaltrials.gov or contact [email protected].
About ocular melanoma (OM)
Ocular melanoma (OM), also known as uveal or choroidal melanoma, develops in the uvea, or uveal tract, of the eye, and is an aggressive and rare eye cancer. No targeted therapies are currently available, and current treatments are associated with serious morbidities. The most common treatment today is placing an invasive radioactive plaque against the exterior of the eye near the tumor, which requires multiple surgeries and can lead to cataracts, retinopathy and loss of vision. The alternative is enucleation, the removal of the eye. OM metastasizes to the liver in about half of all cases (source: OMF), and only 15 percent of patients whose OM has metastasized survive beyond five years after diagnosis (source: ACS).

About light-activated AU-011
AU-011 is a first-in-class targeted therapy in development for the primary treatment of ocular melanoma (OM), also known as uveal or choroidal melanoma, a rare and life-threatening disease. The therapy consists of viral nanoparticle conjugates that bind selectively to cancer cells in the eye. AU-011 has a necrotic mechanism of action and is administered through an intravitreal injection into the eye. Upon activation with an ophthalmic laser, the drug rapidly and specifically destroys the membranes of tumor cells while sparing key eye structures, which may allow for the potential of preserving patients’ vision. AU-011 for OM has been granted orphan drug designation by the U.S. Food and Drug Administration and is currently in clinical testing.
