PRINCETON, N.J.--( BUSINESS WIRE )-- Kanvas Biosciences , a full-stack spatial biology company, today announced results from a clinical trial of fecal microbiota transplantation (FMT) and anti-PD-1 re-induction in microsatellite instability-high (MSI-H) refractory cancers. Presented at the third annual Society for Immunotherapy of Cancer (SITC) meeting, the trial data show that FMT enabled a response to reintroduced anti-PD-1 in patients with anti-PD-1 refractory, MSI-H cancers, and suggest that the gut microbiome affects anti-tumoral immunity in a tumor-agnostic manner. “The strains in our lead drug candidate, KAN-001, were isolated from the same donor who provided FMT material for this clinical trial. All strains present in KAN-001 were delivered to trial participants via FMT, where most if not all successfully engrafted,” said Dr. Kyle Jacoby , Vice President of Clinical Research at Kanvas Bio. “This significantly de-risks the clinical development of KAN-001, which seeks to improve outcomes for cancer patients who have been resistant to immune checkpoint inhibitors (ICIs) like anti-PD-1. With this trial data, Kanvas Bio is in the unique position of having positive human immuno-oncology data on the safety, efficacy and engraftment of the strains that comprise our drug candidate before initiating our own clinical trial for KAN-001.” Participants in the trial included 10 patients with colorectal cancer, two with small bowel adenocarcinomas, one with pancreatic adenocarcinoma, one with endometrial adenocarcinoma and one with a pineal brain tumor. Each participant underwent FMT via colonoscopy, receiving an FMT from a metastatic MSI-H colorectal cancer patient who achieved a complete response (CR) on anti-PD-1 therapy. Result highlights include: Three out of 15 (20%) participants responded to treatment, including one colorectal cancer patient who achieved an ongoing CR >2 years. Engraftment was remarkably high, with significant levels of donor strains in the majority of participants. No incidents of ICI-induced colitis occurred. “The gut microbiome has previously been associated with response to anti-PD-1 therapy, but the mechanisms that impact its effect on anti-tumoral immunity have been unclear,” said Dr. Erez Baruch , presenting author and Medical Oncology Fellow at The University of Texas MD Anderson Cancer Center. “Our trial results demonstrate that FMT enables a response to reintroduced anti-PD-1 in patients with anti-PD-1 refractory, MSI-H cancers.” Baruch is presenting these data as abstract #1266 at SITC on November 9 at the George R. Brown Convention Center in Houston, TX. Kanvas Bio plans to request a pre-Investigational New Drug meeting with the FDA for KAN-001 in January 2025, with the goal of beginning a clinical trial for the drug as soon as possible.

June 12, 2024 -- NKGen Biotech, Inc. (Nasdaq: NKGN) (“NKGen” or the “Company”), a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic and CAR-NK natural killer (“NK”) cell therapeutics, today presented details on its novel allogeneic blood-derived NK cell therapy (“SNK02”) commercial manufacturing and cryopreservation process by Paul Y. Song, MD, Chairman and Chief Executive Officer of NKGen, entitled, “Protecting Patients by Removing Need for Lymphodepletion to Better Preserve Immune Function”. Dr. Song also provided an update on the Company’s initial Phase 1 results using SNK02 to treat patients with advanced refractory solid tumors. Dr. Song’s presentation explored the potential benefits of eliminating pre-treatment lymphodepletion in patients undergoing SNK02 therapy, aiming to safeguard immune function and aid in recovery. Avoiding lymphodepletion before administering cancer treatment can provide many benefits including reduced toxicity, preservation of immune function and potentially enhancing treatment efficacy. The presentation also included a discussion on the results from the Company’s Phase 1 SNK02 clinical study in solid tumors previously disclosed in a publication at the 2024 American Society for Clinical Oncology annual meeting. Moreover, unpublished Phase 1 SNK02 data were also presented. The Phase 1 clinical trial administered SNK02 intravenously (“IV”) weekly for a total of 8 weeks with a starting dose of 6 x 109 SNK02 cells in patients with advanced refractory solid tumors, without lymphodepletion. The primary endpoint was safety based on adverse events, vitals, laboratory tests and physical exams. Tolerability and maximum tolerated dose were also evaluated. SNK02 was found to be well tolerated as a monotherapy and appears to have some clinical activity against pretreated solid tumors despite the lack of lymphodepletion. Dr. Song commented during the presentation, “As most of the focus of NK cell therapy has been for liquid tumors with lymphodepletion, we have always believed that lymphodepletion could be detrimental to patients with solid tumors especially those being treated with immune checkpoint inhibitors, monoclonal antibodies or bispecific therapies where a robust immune response is essential. We therefore set out to develop a commercial scale manufacturing and cryopreservation process which could yield greater than 100,00 doses of SNK02 (cryopreserved enhanced activated allogeneic NK cells) with the idea that large doses could be delivered without lymphodepletion to potentially overcome any host versus graft reaction. We are pleased to show that, despite developing autoantibodies to sustained repeated dosing of our allogeneic product, SNK02 was safe and treatment appeared to stop the progression of several heavily pretreated solid tumors as a monotherapy. We are excited to further explore the efficacy of SNK02 in combination with immune checkpoint inhibitors and antibodies against solid tumors.” In the Phase 1 SNK02 clinical trial, 6 patients, with advanced refractory solid tumors and an average of 4 prior lines of therapy, were enrolled. The median age was 64 years old (range, 44–71), and 4 were male. The cancer subtypes included 2 colorectal cancers, 1 leiomyosarcoma, 1 angiosarcoma, 1 endometrial adenocarcinoma, and 1 undifferentiated pleomorphic sarcoma. Four of six patients completed 8 cycles of SNK02. The best objective response of stable disease (tumor stopped growing) was demonstrated in 100% of patients that completed the 8 cycles. One patient received 18 consecutive weekly doses and another patient received 12 consecutive weekly doses. Out of the 36 doses administered through Cycle 8, there were 17 Grade 1, 3 Grade 2, and 1 Grade 3 adverse events (“AEs”) related to investigational product (“IP”). The Grade 3 AE of increased fatigue resolved after 1 day with no intervention required. There was 1 death on study, which was deemed unrelated to the IP. Auto-antibodies appeared to develop around Cycle 5 and appeared to correlate with AEs. There did not appear to be any correlation with KIR mismatch or HLA subtyping with AEs or tumor response. SNK02 was well-tolerated as a monotherapy and appears to have some clinical activity against pretreated solid tumors despite the lack of lymphodepletion. SNK02 will continue to be studied as a monotherapy and in potential combination treatment regimens with monoclonal antibodies and immune checkpoint inhibitors. SNK02 is a novel cell-based, donor-derived ex vivo expanded allogeneic NK cell immunotherapeutic drug candidate. NKGen Biotech, Inc. is developing SNK02 for the treatment of a broad range of cancers. NKGen is a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic, and CAR-NK NK cell therapeutics.

SNK02 has the potential to be a first-in-class cryopreserved allogeneic NK cell therapy for solid tumors that does not require lymphodepletion before administration, which may lead to better overall synergy in future combination regimens with immune checkpoint inhibitors. In this Phase 1 trial, the best objective response of stable disease was demonstrated in 100% of patients that completed 8 treatment cycles of SNK02. SNK02 was well tolerated as a monotherapy and appears to have some clinical activity against pretreated solid tumors despite the lack of lymphodepletion. SANTA ANA, Calif., May 23, 2024 (GLOBE NEWSWIRE) -- NKGen Biotech, Inc. (Nasdaq: NKGN) (“NKGen” or the “Company”), a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic and CAR-NK natural killer (“NK”) cell therapeutics, today announced an online publication, titled “Interim Analysis of a Phase I Study using Cryopreserved Non-genetically Modified Allogeneic Natural Killer Cells With Enhanced Cytotoxicity (SNK02) in Patients with Advanced Solid Tumors without Lymphodepletion” at the 2024 American Society of Clinical Oncology (“ASCO”) Annual Meeting to be held virtually and at the McCormick Place Convention Center in Chicago, Illinois from May 31–June 4, 2024. This Phase 1 clinical trial is a multi-center, open-label study evaluating the safety and tolerability of SNK02 in participants with pathologically confirmed solid tumors refractory to standard of care therapy. The study drug, SNK02, is a first-in-kind, cryopreserved allogeneic non-genetically modified NK cell product with significant anti-tumor cytotoxicity and over 90% expression of CD16, NKG2D, NKp46, and DNAM-1, that can be consistently produced on a large commercial scale. SNK02 was administered as an intravenous infusion (IV), weekly for eight weeks in patients with advanced solid tumors. The starting dose was 6x109 SNK02 cells. We hypothesized that higher doses of SNK02 (to overcome autodigestion) could be delivered frequently without the need for lymphodepletion and that it might demonstrate activity against solid tumors that have failed multiple prior standard-of-care treatment options. The primary endpoint was safety based on adverse events (AEs), vitals, laboratory tests, and physical exams. Tolerability of SNK02 and maximum tolerated dose were also evaluated. “Interim data from our Phase 1 clinical study utilizing our second NK cell therapy product, SNK02, demonstrated that the treatment was well-tolerated as a monotherapy in patients with solid tumors refractory to standard of care therapy,” said Paul Y. Song, MD, Chairman and CEO of NKGen. “We are particularly excited because SNK02 has the potential to be a first-in-class cryopreserved allogeneic NK cell therapy for solid tumors that does not require lymphodepletion before administration, which may lead to better overall synergy in future combination regimens especially with immune checkpoint inhibitors where a robust T-cell response is needed. Using our proprietary allogeneic manufacturing and cryopreservation processes, we are capable of producing hundreds of thousands of potential doses of enhanced NK cell therapies from materials collected from a single donor. Thus, our potential to treat a significant number of cancer patients with SNK02 is remarkably high. We are pleased to see such promising Phase 1 trial results for both of our unique cell therapy candidates: autologous SNK01 for neurodegenerative disease and allogeneic SNK02 for cancer.” For additional information on the SNK02 clinical trial, please visit https://www.clinicaltrials.gov/ using the identifier NCT05990920.
