"We announced encouraging data from our ongoing clinical studies of both NUC-7738 and NUC-3373, underscoring the potential of our pipeline," said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. "At the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2024 in September, we presented promising data on NUC-7738, a novel agent that profoundly impacts gene expression in cancer cells and targets multiple aspects of the tumor microenvironment. The data from the Phase 2 part of the NuTide:701 study in PD-1 inhibitor-resistant melanoma showed that 9 of the 12 patients achieved disease control when treated with NUC-7738 in combination with pembrolizumab. One of these patients, who had received two prior lines of PD-1 inhibitor-based therapy and had progressed on their latest treatment of ipilimumab plus nivolumab within two months, achieved a 55% reduction in tumor volume. Given the typically poor outcomes in this patient population, with a median progression-free survival of just two to three months under current standard care, we are highly encouraged by the results showing a median progression-free survival of over five months for patients receiving NUC-7738 plus pembrolizumab."

Mr. Griffith added, "We also announced the issuance of a new patent by the United States Patent and Trademark Office covering NUC-7738’s composition of matter. This patent (US12,054,510) is expected to serve as a key component of the intellectual property protection for NUC-7738, which currently consists of over 80 issued patents worldwide."

Mr. Griffith continued, "We recently announced initial data from the ongoing Phase 1b/2 NuTide:303 study of NUC-3373, a targeted thymidylate synthase inhibitor with immune modulating properties, in a manuscript authored by the study’s lead investigators. In this study, NUC-3373 is being combined with pembrolizumab in patients with advanced solid tumors and with docetaxel in patients with lung cancer. Results from the study indicate that NUC-3373 may promote an anti-tumor immune response and potentiate the activity of immune checkpoint inhibitors. We were particularly encouraged to see significant tumor volume reductions and prolonged progression free survival, including a patient with urothelial bladder cancer who achieved 100% reduction in their target lesions. While we were disappointed with the previously announced discontinuation of the NuTide:323 study in patients with metastatic colorectal cancer, we remain optimistic about the potential of NUC-3373."

Mr. Griffith concluded, "Our unwavering commitment to improving treatment outcomes for patients with cancer drives our relentless pursuit of the development of new anti-cancer agents. We look forward to progressing these exciting new medicines and sharing future development plans for NUC-7738 and NUC-3373."

Third Quarter 2024 Financial Highlights and Cash Position

As of September 30, 2024, NuCana had cash and cash equivalents of £11.4 million compared to £11.6 million as of June 30, 2024 and £17.2 million at December 31, 2023. The reduction in cash and cash equivalents during the third quarter was primarily the result of cash used in operating activities, partially offset by £4.7 million in net proceeds raised through its at-the-market (ATM) offering. Subsequent to September 30, 2024, NuCana has raised an additional £1.8 million in net proceeds through its ATM offering. NuCana expects that its cash and cash equivalents as of September 30, 2024, together with amounts raised through its ATM offering subsequent to that date, will be sufficient to fund its planned operations into Q2 2025.

NuCana continues to advance its clinical programs and reported a net loss of £4.5 million for the quarter ended September 30, 2024, as compared to a net loss of £6.7 million for the quarter ended September 30, 2023. Basic and diluted loss per ordinary share was £0.07 for the quarter ended September 30, 2024, as compared to £0.13 per ordinary share for the comparable quarter ended September 30, 2023.

IN8bio Reports Continued Durable Remissions in Phase 1 Trial of INB-200 in Plenary Oral Presentation at the Society for Neuro-Oncology (SNO) Annual Meeting

On November 25, 2024 IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies, reported results from the fully enrolled Phase 1 trial of INB-200 in a plenary oral presentation at the 29th Annual Meeting of the Society for Neuro-Oncology in Houston, TX (Press release, In8bio, NOV 25, 2024, View Source [SID1234648611]). The survival data along with histopathology and radiographic data are indicative of positive treatment effects, which highlight the potential of IN8bio’s genetically modified, chemotherapy-resistant gamma-delta T cells as a potential first-in-class therapy for patients with solid tumor cancers such as glioblastoma (GBM).

"As the clinical trial data continues to mature, this novel immuno-cell therapy leveraging gamma-delta T cells is highly feasible with a well-tolerated safety profile and biological evidence of improved immune surveillance in glioblastoma patients," said Burt Nabors, M.D., Division Director, Neuro-Oncology at the Heersink School of Medicine at the University of Alabama at Birmingham.

"This novel treatment leverages the DNA damage induced by chemotherapy combined with genetically engineered gamma-delta T cells and we believe it represents a significant advancement in the treatment of solid tumor cancers such as GBM," said William Ho, co-founder and CEO of IN8bio. "Glioblastomas are often classified as cold, immune desert tumors due to their limited immune cell infiltration. For the first time, we have confirmed the infiltration of gamma-delta T cells into these tumors through paired tissue biopsies following treatment with INB-200. We are encouraged by the patient follow-up with repeat dose patients demonstrating a 79% increase in median PFS as compared to 6.9 months as reported by the Stupp regimen and an almost 50% increase in median PFS as compared to the 8.3 months in the three patients treated with only a single dose of INB-200 in Cohort 1. The addition of IN8bio’s DeltEx drug resistant immunotherapy (DRI) gamma-delta T cells show the potential for extending PFS in this difficult-to-treat patient population when INB-200 was administered in combination with the current standard-of-care used to treat newly diagnosed GBM patients."

The Phase 1 trial assessed the safety and preliminary efficacy of the addition of DeltEx DRI gamma-delta T cells to maintenance therapy with TMZ. The trial assessed the administration of 1×107 cells per dose across three different dosing regimens increasing from a single dose in Cohort 1, three doses in Cohort 2, and six doses in Cohort 3. A total of 13 patients have been enrolled and treated with INB-200, including three patients in Cohort 1, four patients in Cohort 2 and six patients in Cohort 3.

Key findings from the INB-200 Phase 1 trial:

92% of evaluable patients treated with INB-200 for GBM surpassed a median standard-of-care (Stupp regimen) PFS of 6.9 months, with a majority exceeding their expected PFS based on their age and the MGMT status of their tumors.
One patient with an IDH-mutant glioma remains alive and progression free at over 40.5 months; IDH-mutant patients in a recently published clinical trial demonstrated a median PFS of 11.1 months in the control arm and 27.7 months in the experimental arm.
No treatment-related serious adverse events, dose-limiting toxicities, cytokine release syndrome, infusion reactions, or immune effector cell-associated neurotoxicity syndrome have been reported in any cohort.
The most common treatment emergent adverse events were Grade 1-2 toxicities consisting of white blood cell and platelet count decreases related to standard-of-care TMZ.
Gamma-delta T cells and other immune subsets such as CD3+ and CD8+ T cells were found in relapsed tumor biopsies in two patients after treatment with INB-200, pointing to persistence of DRI gamma-delta T cells.
Gamma-delta T cells were within the normal range post-resection and remained stable with repeated doses (Cohorts 2 and 3), whereas the gamma-delta T cells in Cohort 1 continued to drop after the maintenance cycles with TMZ were initiated. This implies that repeat dosing of gamma-delta T cells may globally benefit the peripheral immune environment.
T cells were low prior to surgery, rose after resection and during the cell collection for the product, were below normal during chemotherapy, and in Cohorts 2 and 3 returned to the normal range following treatment.
Radiographic evaluation pre- and post-treatment included resolution of midline shift in one patient with evidence of changes in enhancement attributed to treatment effect in multiple patients. One subject was found to have a 36% decrease in a lesion attributed to positive treatment effect.
