Loki Therapeutics Announces Publication in Science Translational Medicine Demonstrating Potential of AWAKE-LM-TT as a Treatment for Pancreatic Cancer

On March 28, 2022 Loki Therapeutics, a company developing next-generation therapeutics that leverage vaccination recall antigens to enhance longevity and treat immune-system related diseases, including cancer, reported the publications of research in the journal, "Science Translational Medicine", demonstrating the potential of AWAKE-LM-TT in the treatment of pancreatic cancer (Press release, Loki Therapeutics, MAR 28, 2022, View Source [SID1234611075]). AWAKE-LM-TT, which was developed by Claudia Gravekamp, Ph.D., Loki’s Co-Founder and Associated Professor of Microbiology & Immunology at Albert Einstein School of Medicine, capitalizes on the childhood vaccination for tetanus to generate a powerful and immediate immune response to solid tumors and metastases presenting the tetanus antigens.

The manuscript titled, "Listeria Delivers Tetanus Toxoid Protein to Pancreatic Tumors and Induces Cancer Cell Death in Mice," and co-authored by Dr. Gravekamp, Ph.D., describes research involving a novel approach to treating pancreatic cancer whereby Listeria monocytogenes are used to deliver highly immunogenic tetanus toxoid (TT) proteins directly into tumor cells. This delivery, Listeria-TT, was demonstrated to elicit an immune response, activating tetanus toxoid–specific memory T cells to kill pancreatic ductal adenocarcinoma (PDAC) tumor cells in mice. When combined with gemcitabine (Listeria-TT + GEM), researchers observed an 80% reduction of PDAC tumor burden and an 87% reduction of metastases with an increased survival by 40% compared to nontreated mice, suggesting that Listeria-delivered recall antigens could be an alternative to neoantigen-mediated cancer immunotherapy.

Loki Co-founder and CEO Chris Bradley said, "This study is just the tip of the iceberg when it comes to identifying and finding effective therapeutics to treat difficult cancers. Pancreatic cancer is difficult to identify at an early stage, which makes finding a treatment even more challenging, since it is usually detected at an advanced or late stage. This research demonstrates the significant potential of Loki’s AWAKE-LM-TT as a novel treatment for pancreatic cancer given its ability to harness the childhood vaccination for tetanus toxoid to generate a powerful and immediate immune response to solid tumors and metastases presenting the tetanus antigens."

Dr. Gravekamp commented, "Because of this research, we have a new strategy that can not only be a successful immunotherapy in treating pancreatic cancer, but other cancers as well. Pancreatic tumors are very challenging to treat in that, to the immune system, these tumors do not appear sufficiently ‘foreign’ to attract the immune system’s attention and can usually suppress any immune responses that does occur. Our approach essentially makes these immunologically ‘cold’ tumors hot enough for the immune system to attack and destroy."

Loki is preparing to file an Investigational New Drug (IND) application with the U.S. Food & Drug Administration for a first-in-human clinical program investigating AWAKE-LM-TT in the treatment of pancreatic cancer. Upon receiving FDA clearance for the IND, Loki anticipates initiating a Phase 1 clinical trial in the second half of 2022.

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: "We are serious about leading a revolution in oncology, which is why we continue to pioneer new ways to target cancer earlier and with greater precision, for the benefit of patients. Our data at AACR (Free AACR Whitepaper) from next-wave Immuno-Oncology medicines, PARP inhibitors and antibody drug conjugates demonstrate the potential of our diverse portfolio and reflect our vision to target cancer from every angle."

Introducing the next wave of IO therapies
The first clinical results will be shared for MEDI5752, a novel bispecific antibody, that simultaneously targets the immune checkpoint proteins PD-1 and CTLA-4, in solid tumours. Bispecific antibodies are a promising IO approach that combines the potential benefits of two medicines in one. MEDI5752 was engineered to achieve combined blockade of CTLA-4 and PD-1, to improve the therapeutic index when compared to targeting these proteins using two separate medicines.

A presentation from the NeoCOAST randomised Phase II trial in resectable, early-stage non-small cell lung cancer will highlight improved disease responses with novel Imfinzi (durvalumab) combinations including with oleclumab, an anti-CD73 monoclonal antibody, and with monalizumab1, an anti-NKG2A checkpoint inhibitor, when compared to Imfinzi alone.

Additionally, four presentations will describe novel molecules targeting interleukin-12 (IL-12) and leukaemia inhibitor factor (LIF) and illustrate the potential of targeting non-redundant mechanisms to modulate the immune tumour microenvironment.

Building the next generation of PARP inhibitors
The first data will be presented from the PETRA Phase I clinical trial investigating AZD5305, a next-generation PARP1-selective inhibitor, in patients with tumours harbouring specific homologous recombination repair gene mutations. AZD5305 is designed to selectively target PARP1, killing cancer cells by targeting tumour cell DNA damage repair mechanisms. This approach could allow PARP inhibitors to expand into new settings and offer new opportunities for combinations with DNA damage pathway activating agents such as ADCs. Preclinical data will be presented that support this hypothesis showing the activity of Enhertu (trastuzumab deruxtecan) in combination with DDR agents including PARP1-selective inhibitors.

Additionally, four presentations will describe the discovery of AZD9574, a novel PARP1 selective inhibitor designed to cross the blood brain barrier to enable the targeting of primary and secondary brain malignancies.

Innovative approaches to deliver a next-wave ADC
The first preclinical data will be shared on AZD8205, a novel ADC targeting B7-H4, a protein overexpressed in a range of solid tumours. This molecule is the first ADC to incorporate AstraZeneca’s proprietary linker technology, demonstrating the Company’s progress in establishing in-house ADC expertise and building leadership in this field.

"There are many effective treatments available for colorectal cancer, however, recent genetic studies have revealed that some patients do not respond adequately to standard treatment. We are very pleased that now we have the opportunity to offer the combination therapy of Perjeta and Herceptin to these patients, as a new treatment option based on personalized medicine," said Chugai’s President and CEO, Dr. Osamu Okuda. "HER2-positive colorectal cancer is a rare subtype that accounts for 1~5% of all colorectal cancers. This approval opens the way for personalized medicine for this subtype for the first time in Japan and overseas. I would like to thank everyone who supported us for this approval, especially those who participated in the investigator-initiated study which formed the basis of this trial, including patients, their families and medical professionals. We are committed to providing information on the proper use of this combination therapy so that it may contribute to the treatment of colorectal cancer."

The approval is based on the results of an investigator-initiated phase II clinical trial (TRIUMPH study) conducted in Japan that evaluated the efficacy and safety of the combination of Perjeta and Herceptin in 30 patients with HER2-positive, curatively unresectable advanced or recurrent colorectal cancer who had previously undergone chemotherapy. The primary endpoint was the objective response rate as determined by the investigator’s judgment. Objective response was observed in 29.6% of patients confirmed HER2 expression in tumor tissue and 28.0% of patients diagnosed with HER2-positive and RAS wild-type by liquid biopsy. Major adverse events included infusion-related reactions, diarrhea, decreased appetite, nausea, stomatitis and nasopharyngitis.

HER2 protein overexpression and gene amplification should be determined with the pathological testing kit VENTANA ultraView Pathway HER2 (4B5) provided by Roche Diagnostics K.K. and Pathvision HER-2 DNA Probe Kit provided by Abbott Japan Joint company. Both tests obtained regulatory approval on March 17, 2022 and March 10, 2022, respectively, as companion diagnostics for Perjeta and Herceptin to identify patients with HER2 positive colorectal cancer who may benefit from the combination therapy.

About Perjeta

Perjeta is a humanized monoclonal antibody that targets human epidermal growth factor receptor type 2 (HER2), which is involved in the growth of tumor cells. Perjeta in combination with Herceptin blocks the HER-signaling system more extensively. The drug was launched in 2013 for "inoperable or recurrent HER2-positive breast cancer." The indication was amended as "HER-2 positive breast cancer," after obtaining regulatory approval for the additional indication of "neoadjuvant and adjuvant therapy in HER2-positive breast cancer" in 2018.

About Herceptin

Herceptin, like Perjeta, is a humanized monoclonal antibody that targets human epidermal growth factor receptor type 2 (HER2), which is involved in the growth of tumor cells. Herceptin was launched in 2001 for "metastatic breast cancer overexpressing HER2." In 2011, it was approved for the treatment of patients with "advanced or recurrent gastric cancer overexpressing HER2 not amenable to curative resection," and in 2021 for "advanced or recurrent HER2-positive salivary gland cancer not amenable to curative resection."

"There remains a clear need for safe and efficacious antibody treatments against COVID-19, especially those less susceptible to mutational drift. We believe our three-antibody cocktail, IMM-BCP-01, has strong potential to address that unmet need. We are pleased the FDA has given us a safe-to-proceed notification and lifted the clinical hold for our Investigational New Drug (IND) application," stated Purnanand Sarma, Ph.D., President and CEO of Immunome.

"Additionally, we continue to progress IMM-ONC-01, our novel, IL-38-targeting innate immune checkpoint inhibitor, towards an IND submission in the second half of 2022," Sarma continued. "Our preclinical work is ongoing, and we have analyzed IL-38 expression across nearly 60 tumor subtypes and we have confirmed a high frequency of expression in difficult to treat cancers, such as head and neck squamous cell carcinoma, gastroesophageal squamous carcinoma, and squamous lung carcinoma."

Fourth Quarter and Subsequent Highlights

·Demonstrated In Vitro Efficacy of IMM-BCP-01 Against SARS-CoV-2 Omicron Variant in Live Virus Testing. In February 2022, Immunome announced that IMM-BCP-01 demonstrated effective neutralization of the Omicron variant of COVID-19 in in vitro testing. The combination of two antibodies in Immunome’s antibody cocktail, IMM20253/IMM20184, demonstrated neutralization of the Omicron variant within 3.5-fold potency compared to a preclinical version of sotrovimab in a head-to-head test using live virus samples. Additionally, IMM20253 exhibited a novel mechanism of action not reported in any other EUA antibodies by promoting a proteolytic cleavage of the portion of the spike protein needed for ACE2 binding.

·IMM-BCP-01 IND Application for the Treatment of COVID-19. In March 2022, the FDA communicated that the clinical study can be initiated for our antibody cocktail for the treatment of SARS-CoV-2 following a brief clinical hold. Immunome is continuing its ongoing clinical preparations ahead of the Phase 1b trial.
