Jeffrey Miller, MD, Deputy Director, Masonic Cancer Center, University of Minnesota commented, "These studies demonstrate the adaptability of the TriKE platform to optimize TriKE constructs and candidate selection in order to address unmet medical needs. We continue to work with our partners at GT Biopharma in moving the TriKE platform forward."

The Company’s TriKE product candidates are single-chain, tri-specific scFv recombinant fusion proteins composed of the variable regions of the heavy and light chains (or heavy chain only) of anti-CD16 antibodies, wild-type or a modified form of IL-15 and the variable regions of the heavy and light chains of an antibody designed to precisely target a specific tumor antigen. GT Biopharma utilizes the NK stimulating cytokine human IL-15 as a crosslinker between the two scFvs which is designed to provide a self-sustaining signal leading to the proliferation and activation of NK cells thus enhancing their ability to kill cancer cells mediated by antibody-dependent cell-mediated cytotoxicity (ADCC). GT Biopharma has an exclusive worldwide license agreement with the University of Minnesota to further develop and commercialize cancer therapies using proprietary TriKE technology developed by researchers at the university to target NK cells to cancer.

"We continue to be encouraged by the data from our Trike program being conducted by leading NK cell experts at the University of Minnesota. These findings have supported us with the confidence to proceed with our first-in-class TriKE, Phase 1 study," commented Raymond Urbanski, M.D., Ph.D., Chief Executive Officer of GT Biopharma. "We are grateful to renowned NK cell expert, Jeffrey Miller, MD, Deputy Director, Masonic Cancer Center, University of Minnesota and his team, and look forward to providing further updates as we continue to advance what we believe to be a potentially revolutionary product candidate."

Graduate student, Upasana Sunil Arvindam, MSc, BSc, working with Drs. Miller and Felices at the University of Minnesota, presented the abstract titled, "CD16-IL15-CLEC12A Tri-specific Killer Engager (TriKE) Drives NK Cell Expansion, Activation, and Antigen Specific Killing of Cancer Stem Cells in Acute Myeloid Leukemia," as part of the Acute Myeloid Leukemia: Novel Therapy, Excluding Transplantation: Poster I session at ASH (Free ASH Whitepaper). To access the presented poster, click here.

For the preclinical study, Dr. Arvindam and her team developed a 1615CLEC12A TriKE molecule to target AML cells using Natural Killer (NK) cells. This molecule contains an anti-CD16 camelid nanobody to activate NK cells, an anti-CLEC12A single chain variable fragment (scFv) to engage cancer targets, and an IL-15 molecule that drives NK cell priming, expansion and survival.

The CLEC12A TriKE was developed in a mammalian cell system to ensure that appropriate post-translational modifications are present. The researchers confirmed that the TriKE binds specifically to HL-60 and THP-1 target cells that express CLEC12A compared to Raji cells that do not express CLEC12A. Treatment of peripheral blood mononuclear cells (PBMCs) with the CLEC12A TriKE drives a significant increase in NK cell specific proliferation over 7 days as measured by Cell Trace dilution compared to treatment with a CLEC12A scFv or IL-15 alone (69.7 ± 6.7% vs 11.9 ± 2.5% vs 38.4 ± 7.3%). In these assays, the efficacy of the CLEC12A TriKE was comparable to the CD33 TriKE. The data demonstrates that the CLEC12A TriKE drives NK cell specific proliferation, degranulation, cytokine secretion, and killing of tumor targets in vitro. Apart from AML, CLEC12A is expressed on cancer cells and LSCs in patients with myelodysplastic syndromes (MDS).

The presented preclinical findings highlight the clinical potential of the CLEC12A TriKE individually or in combination with the CD33 TriKE for the treatment of MDS and AML and ultimately led to the establishment of a first-in-human Phase 1 study with GTB-3550 (OXS-3550), its first-in-class (TriKE), for the treatment of AML, MDS and mastocytosis, which GT Biopharma recently announced. The study will be led by Principal Investigator, Sarah A. Cooley, MD, MS, Associate Professor, Division of Hematology, Oncology and Transplantation at Masonic Cancer Center, University of Minnesota.

The abstract titled, "Induced Pluripotent Stem Cell-Derived NK Cells Genetically Modified to Express NKG2C/DAP12 Mediate Potent Function When Targeted through an NKG2C/IL-15/CD33 Tri-Specific Killer Engager (TriKE)," was presented in an oral presentation by graduate student Emily Chiu, PhD, Medical School, University of Minnesota. To access the presentation slides, click here.

Having demonstrated stable expression and intact signaling of NKG2C/DAP12 in iNK cells, Dr. Chiu and her team next created a TriKE molecule with single chain Fv fragments specific for NKG2C (on iNK cells) and CD33 (on AML cells), as well as IL15 (to support iNK cell survival and proliferation). Without the addition of NKG2C/CD33/IL15 TriKE, the frequencies of both NKG2C iNK cells and NKG2C/DAP12 iNK cells producing IFNg was relatively low (< 10%). Addition of NKG2C/IL15/CD33 TriKE in the assay markedly increased the frequency of IFNg production by both NKG2C iNK cells (19.1%) and NKG2C/DAP12 iNK cells (25.8%). Finally, the team directly tested the ability of the NKG2C/IL15/CD33 TriKE molecule to trigger target killing by engineered iNK cells monitored over a 24hour period. THP1 target cells were dye labeled and plated in wells with either NKG2C iNK cells or NKG2C/DAP12 iNK cells at a 5:1 effector-to-target ratio with or without NKG2C/CD33/IL15 TriKE. The researchers found that in the absence of TriKE, there was no killing of THP1 targets. In contrast, both NKG2C iNK cells and NKG2C/DAP12 iNK cells mediated robust THP1 killing with the addition of NKG2C/CD33/IL15 TriKE, with NKG2C/DAP12 iNK cells exhibiting the strongest response.

Results from the study provided a proof-of-concept that iNK cells engineered to express NKG2C/DAP12 can be used in combination with a novel NKG2C/IL15/CD33 TriKE molecule to effectively target cancer cells. Engaging NK cells through NKG2C, restricted to adaptive NK cells or genetically modified iPSC will be more specific than CD16, which will bind to CD16A on NK cells but also have off-target binding to CD16B on neutrophils. Because of the enormous expansion and engineering capacity of the iNK cell platform, the Company believes it is in a unique position to create an "off-the-shelf" NK cellular therapy that is targeted, specific and efficacious.

About Acute Myelogenous Leukemia (AML)

AML is the most common form of adult leukemia with 21,000 new cases expected in 2018 alone, according to the American Cancer Society. AML patients typically receive frontline therapy, most commonly chemotherapy, which includes cytarabine and an anthracycline, a therapy that has not changed in over 40 years. However, there remains a significant unmet need in these therapies with about half of AML patients experiencing relapses or requiring alternative therapies. The Company is developing GTB-3550 to serve as a relatively safe, cost-effective, and easy-to-use therapy for resistant/relapsing AML and could also be combined with chemotherapy as frontline therapy thus targeting the larger patient population

On December 5, 2018 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) and granted Priority Review for Tecentriq (atezolizumab), in combination with carboplatin and etoposide (chemotherapy), for the initial (first-line) treatment of people with extensive-stage small cell lung cancer (ES-SCLC) (Press release, Genentech, DEC 5, 2018, View Source [SID1234531908]). The FDA is expected to make a decision on approval by March 18, 2019. A Priority Review designation is granted to medicines that the FDA has determined to have the potential to provide significant improvements in the treatment, prevention or diagnosis of a serious disease.

"It’s been more than 20 years since there has been a new initial treatment option for extensive-stage small cell lung cancer that delivers a clinically meaningful survival benefit," said Sandra Horning, M.D., chief medical officer and head of Global Product Development. "We are working closely with the FDA to bring this Tecentriq-based regimen to people with this difficult-to-treat type of lung cancer as soon as possible."

This sBLA is based on results from the Phase III IMpower133 study, which met its co-primary endpoints of overall survival (OS) and progression-free survival (PFS) in the initial treatment of people with ES-SCLC. The safety profile of the combination was consistent with the safety profiles of the individual medicines, and no new safety signals were identified.

Tecentriq is currently approved by the FDA to treat people with metastatic non-small cell lung cancer (NSCLC) who have disease progression during or following platinum-containing chemotherapy, and have progressed on an appropriate FDA-approved targeted therapy if their tumor has ALK or EGFR gene abnormalities.

About the IMpower133 study

IMpower133 is a Phase III, multicenter, double-blinded, randomized placebo-controlled study evaluating the efficacy and safety of Tecentriq in combination with chemotherapy (carboplatin and etoposide) versus chemotherapy (carboplatin and etoposide) alone in chemotherapy-naïve people with ES-SCLC. The study enrolled 403 people who were randomized equally (1:1) to receive:

Tecentriq in combination with carboplatin and etoposide (Arm A), or
Placebo in combination with carboplatin and etoposide (Arm B, control arm)
During the treatment-induction phase, people received treatment on 21-day cycles for four cycles, followed by maintenance with Tecentriq or placebo until progressive disease (PD) as assessed by the investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). Treatment could be continued until persistent radiographic PD or symptomatic deterioration was observed.

The co-primary endpoints were:

PFS as determined by the investigator using RECIST v1.1 in the intention-to-treat (ITT) population
OS in the ITT population
IMpower133 met its OS and PFS co-primary endpoints as per the study protocol. The analysis showed that Tecentriq and chemotherapy helped people live significantly longer compared to chemotherapy alone (OS=12.3 versus 10.3 months; hazard ratio [HR] = 0.70, 95 percent CI: 0.54-0.91; p=0.0069) in the ITT population. The one-year OS rate for people who received the Tecentriq-based combination was 51.7 percent compared to 38.2 percent for people who received chemotherapy alone. The Tecentriq-based combination also significantly reduced the risk of disease worsening or death compared to chemotherapy alone (PFS=5.2 versus 4.3 months; HR=0.77; 95 percent CI: 0.62-0.96; p=0.017). The one-year PFS rate for people who received the Tecentriq-based combination was 12.6 percent compared to 5.4 percent for people who received chemotherapy alone. Safety for the Tecentriq and chemotherapy combination appeared consistent with the known safety profile of the individual medicines, and no new safety signals were identified with the combination. Grade 3-4 treatment-related adverse events (AEs) were reported in 56.6 percent of people receiving Tecentriq plus chemotherapy compared to 56.1 percent of people receiving chemotherapy alone.

About lung cancer

According to the American Cancer Society, it is estimated that more than 234,000 Americans will be diagnosed with lung cancer in 2018. Lung cancer can be broadly divided into two major types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most prevalent type, accounting for around 85 percent of all lung cancer cases, and SCLC accounting for approximately 15 percent of all cases. The majority (approximately 70 percent) of people with SCLC are diagnosed with ES-SCLC.

About Tecentriq (atezolizumab)

Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

Tecentriq U.S. Indication (pronounced ‘tē-SEN-trik’)

Tecentriq is a prescription medicine used to treat:

A type of bladder and urinary tract cancer called urothelial carcinoma.

Tecentriq may be used when your bladder cancer:
has spread or cannot be removed by surgery, and if you have any one of the following conditions:
you are not able to take chemotherapy that contains a medicine called cisplatin, and your doctor has tested your cancer and found high levels of a specific protein on your cancer called programmed death-ligand 1 (PD-L1), as determined by an FDA-approved test, or
you are not able to take chemotherapy that contains any platinum regardless of PD-L1 status on your cancer, or
you have tried chemotherapy that contains platinum, and it did not work or is no longer working
The approval of Tecentriq in these patients is based on a study that measured response rate and duration of response. There is an ongoing study to confirm clinical benefit.

A type of lung cancer called non-small cell lung cancer (NSCLC).

Tecentriq may be used when your lung cancer:
has spread or grown, and
you have tried chemotherapy that contains platinum, and it did not work or is no longer working
If your tumor has an abnormal EGFR or ALK gene, you should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working.

It is not known if Tecentriq is safe and effective in children.

Important Safety Information

What is the most important information about Tecentriq?

Tecentriq can cause the immune system to attack normal organs and tissues and can affect the way they work. These problems can sometimes become serious or life threatening and can lead to death.

Patients should call or see their healthcare provider right away if they get any symptoms of the following problems or these symptoms get worse.

Tecentriq can cause serious side effects, including:

Lung problems (pneumonitis)–signs and symptoms may include new or worsening cough, shortness of breath, and chest pain
Liver problems (hepatitis)–signs and symptoms of hepatitis may include yellowing of the skin or the whites of the eyes, severe nausea or vomiting, pain on the right side of the stomach area (abdomen), drowsiness, dark urine (tea colored), bleeding or bruising more easily than normal, and feeling less hungry than usual
Intestinal problems (colitis)–signs and symptoms of colitis may include diarrhea (loose stools) or more bowel movements than usual, blood or mucous in the stools or dark, tarry, sticky stools, and severe stomach area (abdomen) pain or tenderness
Hormone gland problems (especially the thyroid, adrenal glands, pancreas, and pituitary)–signs and symptoms that the hormone glands are not working properly may include headaches that will not go away or unusual headaches, extreme tiredness, weight gain or weight loss, dizziness or fainting, feeling more hungry or thirsty than usual, hair loss, changes in mood or behavior (such as decreased sex drive, irritability, or forgetfulness), feeling cold, constipation, the voice gets deeper, urinating more often than usual, nausea or vomiting, and stomach area (abdomen) pain
Problems in other organs–signs and symptoms may include severe muscle weakness, numbness or tingling in hands or feet, confusion, blurry vision, double vision, or other vision problems, changes in mood or behavior, extreme sensitivity to light, neck stiffness, eye pain or redness, skin blisters or peeling, chest pain, irregular heartbeat, shortness of breath, or swelling of the ankles
