Comparison of Antitumor Effects of Combinations of Immune Checkpoint Inhibitors With Dendritic Cells Intratumorally Injected into Irradiated Mouse Adenocarcinoma

Article

Author: Kang, Hyun Bon ; Koh, Eun-Kyoung ; Lee, Hong-Rae ; Kim, YoungHee ; Song, Jin Hoo ; Park, Ga-Young ; Son, Woo-Chang ; Park, You-Soo ; Kim, Dong Won

Dendritic cells (DCs) are specialized immune cells that play a crucial role in presenting antigens and activating cytotoxic T lymphocytes to combat tumors. The immune checkpoint receptor programmed cell death-1 (PD-1) can bind to its ligand programmed cell death-ligand 1 (PD-L1), which is expressed on the surface of cancer cells. This interaction suppresses T-cell activation and promotes immune tolerance. Radiation therapy can increase the expression of PD-L1 on tumor cells, which can lead to a decrease in the effectiveness of the treatment, and detailed studies are needed to understand the mechanisms. As many patients develop resistance to chemotherapy and radiotherapy—either through lack of response or cancer recurrence—there is a critical need to maximize synergistic effects by selecting combination treatments that offer improved therapeutic efficacy with minimal side effects. In the present study, immature DCs (iDCs) were introduced directly into irradiated tumor sites (referred as IR/iDCs), and immune checkpoint blockades (ICBs) were administered intraperitoneally. We confirmed the antitumor effect of combining IR/iDCs and ICBs by examining tumor growth and mouse survival. The proportion of CD4+ and CD8+ T cells in splenocytes increased in the IR/iDCs-treated groups. Combining IR/iDCs with an anti-PD-L1 antibody led to a significant reduction in distant tumor growth and improved mouse survival rates compared with IR/iDCs alone or IR/iDCs + anti-PD-1 antibody. These findings suggest that integrating radiotherapy, DC-based immunotherapy, and ICB, specifically targeting PD-L1, may be an effective cancer treatment strategy.

Colorectal cancer stem cells develop NK cell resistance via homotypic cell-in-cell structures suppressed by Stathmin1

Article

Author: Teng, Hao-Wei ; Hwang, Wei-Lun ; Lan, Hsin-Yi ; Lin, Yen-Yu ; Lin, Wen-Chun ; Wang, Ya-Pei

Rationale: Advances in cancer therapies have significantly improved patient survival; however, tumors enriched in cancer stem cells (CSCs) have poor treatment responses. CSCs are a key source of tumor heterogeneity, contributing to therapeutic resistance and unfavorable patient outcomes. In the tumor microenvironment (TME), cell-in-cell (CIC) structures, where one cell engulfs another, have been identified as markers of poor prognosis. Despite their clinical relevance, the mechanisms underlying CIC formation across different tumor cell subpopulations remain largely unknown. Elucidating these processes could provide novel insights and therapeutic opportunities to address aggressive, treatment-resistant cancers. Method: Fluorescent mCherry-carrying colorectal cancer stem cells (CRCSCs) were expanded as spheroids in serum-free media and cocultured with either parental cancer cell-expressing Venus fluorescent protein or CFSE dye-stained immune cells (T cells, M1/M2 macrophages, neutrophils, and NK cells) or treated with EGFR- or PD-L1-targeting antibodies to assess the formation of CIC structures. Genes potentially crucial for the formation of CIC structures were knocked down or overexpressed, and their effects on CIC formation were evaluated. The clinical relevance of the in vitro findings was confirmed through analysis of formalin-fixed, paraffin-embedded (FFPE) human colorectal cancer (CRC) specimens. Results: CRCSCs have a strong predilection for serving as the outer cell in a CIC structure and forming homotypic CIC structures predominantly with parental CRC cells. The frequency of CIC structure formation increased when the cells were exposed to anti-PD-L1 antibody treatment. Both the outer CRCSC in a CIC structure and CRCSCs released from a homotypic CIC structure showed enhanced resistance to the cytotoxicity of NK-92MI cells. Restoration of Stathmin1 (STMN1) expression but not RAC1 knockdown in CRCSCs reduced the homotypic CIC frequency, disrupted the outer cell fate in CIC structures, and increased cell susceptibility to NK-92MI cytotoxicity. In CRC patients, CIC structures are associated with poor tumor differentiation, negative STMN1 expression, and poor prognosis. Conclusion: CSCs play a crucial role in informing CIC structures in CRC. CIC structure formation partially depends on low STMN1 expression and confers a survival advantage under NK cytotoxicity. Targeting this pathway may significantly improve immunotherapy's efficacy for CRC patients.

Fluorouracil enhances the anti-pancreatic cancer effect of anti-PD-L1 antibodies via up-regulating the expression of PD-L1 in cancer cells

Article

Pancreatic cancer is characterized by occult onset, low early diagnosis rate, rapid progress, and poor prognosis. Due to the low response rate and low programmed cell death ligand 1 (PD-L1) expression in pancreatic cancer, the therapeutic application of PL-L1 inhibitors in pancreatic cancer is greatly limited. In vitro studies showed that the expression of PD-L1 increased in pancreatic cancer cells stimulated by fluorouracil (5-FU). We aim to explore the combined effect of 5-FU and anti-PD-L1 antibodies and to provide a reference for the clinical application of PD-L1 antibodies in pancreatic cancer. In the current study, male BALB/c mice were adopted to construct a tumor-bearing model of pancreatic cancer cells. 5-FU and anti-mouse PD-L1 antibodies were combined and administered to evaluate their synergistic effects. The enhancing immune cytotoxicity effect of 5-FU sensitizing the anti-PD-L1 antibody in vivo and in vitro was analyzed by immunohistochemistry and western blot assays. Results showed that 5-FU and anti-PD-L1 antibody combination increased the expression of PD-L1 and IFN-γ, and infiltration of CD8 + T lymphocytes in pancreatic xenograft tumor tissues, which was proven by immunohistochemistry and western analysis. Moreover, the combination with the 5-FU remarkably enhanced the immune cytotoxicity of anti-PD-L1 antibodies in mice. In vitro analysis demonstrates that 5-FU increases the expression of PD-L1 on the surface of pancreatic cancer cell lines via up-regulating nuclear factor kappa B (NF-κB) and Protein kinase B (AKT) pathways. This synergistic effect could be abolished by NF-κB and AKT inhibitors.

Sun Pharma to acquire Checkpoint Therapeutics and its anti-PD-L1 antibody

After months of searching for a partner for its recently approved cancer drug, Checkpoint Therapeutics has instead secured a buyer. India’s Sun Pharma is acquiring the immuno-oncology biotech for $4.10 per share, or roughly $355 million in cash, according to a Monday release . This purchase price is a 66% premium of Checkpoint’s stock $CKPT after the market closed Friday. The Waltham, MA-based biotech’s stock was up by as much as 65% before it reopened Monday. If its anti-PD-L1 antibody Unloxcyt is approved in certain markets in Europe, shareholders will also receive an upfront cash payment of $4.10 for each stock they hold. The deal is expected to close in the second quarter of this year. Checkpoint has said it was searching for a US commercial partner since Unloxcyt (cosibelimab) secured FDA approval in December for advanced skin cancer. Unloxcyt is Checkpoint’s first commercial drug. Sun Pharma, known for its generic drugs and the largest pharma company in India, is planning to use its global footprint to expand access to Unloxcyt, according to the Monday release. The company is a manufacturing giant with around 43 production facilities across six continents, according to its website. Unloxcyt was initially rejected by the FDA in December 2023 over manufacturing issues at its unnamed third-party contract manufacturer. The biotech then refiled its application in July 2024. In 2020, Checkpoint tapped Samsung Biologics to manufacture cosibelimab, with the deal set to expire in 2030, according to an SEC filing .

AIM ImmunoTech Bolsters Intellectual Property Estate for Ampligen® with Issuance of Two Key U.S. Patents

Extends certain exclusive U.S. rights to Ampligen for cancer and ME/CFS through 2039 Management discusses patent issuance and what this means in a brief video: here OCALA, Fla., Nov. 27, 2023 (GLOBE NEWSWIRE) -- AIM ImmunoTech Inc. (NYSE American: AIM) (“AIM” or the “Company”) today announced that the U.S. Patent and Trademark Office (USPTO) has issued U.S. patent No. 11,813,279 and 11,813,281 for Ampligen® titled “Compositions for cancer therapy and methods,” and “Methods for improving exercise tolerance in myalgic encephalomyelitis patients,” respectively. AIM Chief Executive Officer Thomas K. Equels stated: “Our ongoing effort to expand and solidify AIM’s global intellectual property estate is a foundational component of our development strategy for Ampligen. AIM’s expectation for Ampligen — both as a therapeutic for people suffering from dire diseases and as a valuable asset for our stockholders — is the driving force behind our multiple clinical studies in oncology, ME/CFS and Post-COVID conditions. These two new U.S. patents will serve to further strengthen the potential financial future of our company by extending certain sole rights to Ampligen and for these uses to 2039.” Click here to watch a brief video from the AIM management team discussing the issuance of the U.S. patents and what it means for the pipeline development strategy for Ampligen®. Oncology Patent The new patented methods involve the administration of a unique combination of two compounds to patients suffering from pancreatic cancer, renal cell carcinoma, colorectal cancer and/or melanoma. The first compound is an anti-PD-L1 antibody and the second compound is Ampligen. The combination of these compounds is designed to work synergistically to enhance the effectiveness of the treatment. The company believes this novel approach promises to revolutionize the treatment landscape for cancers that have historically been challenging to treat. As symptoms appear only in advanced stages and these cancers are extremely difficult to diagnose without deliberate screening, these cancers contribute to high mortality rates and are a significant burden on public health. The advancement, as claimed in the issued patent, is expected to significantly improve treatment outcomes for patients suffering from these cancers in ongoing and upcoming clinical trials. The granting of U.S. Patent No. 11,813,279 is not only a testament to AIM’s dedication to pioneering cancer treatment, but also opens new avenues for future research and therapy development. AIM, as patent holder, will have the sole rights to exclude other companies from using the claimed method for research or for treatment until August 9, 2039. On the other hand, AIM, either independently or with strategic licensed partners, will be able to continue refining and enhancing this patented treatment method. ME/CFS Patent Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating condition characterized by extreme fatigue, pain, and cognitive issues. The Centers for Disease Control and Prevention (CDC) estimates that between 836,000 and 2.5 million Americans suffer from ME/CFS. Addressing these severe symptoms has been a complex challenge for healthcare professionals. However, the issuance of U.S. Patent No. 11,813,281 represents a major leap forward, bringing new hope to those impacted by the enduring and debilitating symptoms of ME/CFS. The novel methods outlined in the new patent claims involve, at least, identifying individuals who have experienced ME/CFS symptoms for 2 to 8 years — a feature identified through extensive research — and treating these symptoms by administering Ampligen. This precision in treatment timing reflects a targeted, cutting-edge approach to personalized medicine in ME/CFS care and is expected to lead to significant improvements and effectiveness in ME/CFS symptoms in this population. U.S. Patent No. 11,813,281 bestows AIM ImmunoTech Inc. with the sole rights to exclude others from practicing the claimed methods of treating ME/CFS symptoms using Ampligen until January 12, 2040. This exclusivity fortifies AIM's position in the market by enabling development of a distinctive and unparalleled treatment option. Additionally, the patent paves the way for strategic alliances and licensing deals, endowing AIM with the unique opportunity to conduct further research and development of the claimed method, either independently or with licensed partners, to continue refining and enhancing this patented treatment method. About AIM ImmunoTech Inc. AIM ImmunoTech Inc. is an immuno-pharma company focused on the research and development of therapeutics to treat multiple types of cancers, immune disorders and viral diseases, including COVID-19. The company’s lead product is a first-in-class investigational drug called Ampligen® (rintatolimod), a dsRNA and highly selective TLR3 agonist immuno-modulator with broad spectrum activity in clinical trials for globally important cancers, viral diseases and disorders of the immune system.
