"We are very pleased to share the compelling preclinical and translational data that enabled us to select the dose for our Phase 2 trials of SRF388," said Alison O’Neill, M.D., chief medical officer. "These data add to the growing body of evidence supporting our belief that IL-27 is a highly immunosuppressive cytokine that serves as a critical regulator of checkpoint protein expression, and treatment with SRF388 shuts down IL-27 signaling. We look forward to providing a clinical update on the program at a scientific conference later in the first half of 2022."

Summary of key SRF388 data:

Pharmacokinetics (PK) from the dose-escalation phase of the SRF388 Phase 1 study were linear, with no dose-limiting toxicities reported.
The concentration of SRF388 associated with optimal antitumor activity in a preclinical mouse model was determined to be approximately 20-fold above the concentration needed for complete inhibition of whole blood phosphorylated STAT1; this concentration of SRF388 was reached and exceeded in patients at a dose of 10 mg/kg.
As previously reported, one patient with squamous non-small-cell lung cancer experienced a confirmed partial response per RECIST v1.1 at this dose.
Changes in the concentration of several serum cytokines and chemokines were observed after SRF388 treatment, including a subset of these biomarkers that correlated with clinical response.
An increase in serum IL-27 levels was observed after SRF388 treatment, a phenomenon described for other anti-cytokine antibodies due to altered clearance of the cytokine-antibody complex.
SRF388 translational data supports the recommended Phase 2 monotherapy dose selection of 10 mg/kg administered intravenously every four weeks, which is being studied in dedicated expansion cohorts of treatment-refractory clear cell renal cell carcinoma (RCC), non-small-cell lung cancer (NSCLC) and hepatocellular carcinoma (HCC) in the ongoing Phase 1 study (NCT04374877).
The efficacy of adding IL-27 blockade with SRF388 to atezolizumab/bevacizumab in treatment-naïve HCC is also being explored in a placebo-controlled randomized Phase 2 study.
The AACR (Free AACR Whitepaper) e-poster website will be launched on Friday, April 8, 2022, and posters will remain available to registered attendees through Wednesday, July 13, 2022. The SRF388 poster can also be found on Surface Oncology’s website.

"We have made excellent progress advancing compounds in our preclinical pipeline," said Taylor Schreiber, M.D., Ph.D., Chief Executive Officer of Shattuck. "Data from our SL-9258 compound indicate potent modulation of myeloid cells, T cells, and cytokines, including IL-2, which collectively translated to superior anti-tumor activity in comparison to TIGIT and PD-L1 antibodies in a preclinical model of PD-1 acquired resistance. In addition, multiple compounds from our gamma delta T cell engager, or GADLEN, platform have shown specific anti-tumor activity in preclinical studies, which will help guide our lead candidate selection and clinical development strategy. We look forward to nominating our next clinical product candidate in 2022."

Details of the presentations are as follows:

Abstract title: LIGHT (TNFSF14) costimulation with TIGIT blockade broadens the activity of checkpoint inhibitors (CPIs) into checkpoint inhibitor refractory and resistant tumors through targeted myeloid cell and effector lymphocyte activation

Shattuck presented preclinical data for SL-9258 (TIGIT-Fc-LIGHT), a bispecific fusion protein from its ARC platform, demonstrating that SL-9258 simultaneously provides checkpoint blockade to all tumor-expressed PVR ligands and broadens immune costimulation by the TNF ligand known as LIGHT. LIGHT’s ability to bind and activate CD8+ T and natural killer cells through interactions with one of its receptors known as HVEM and myeloid cells through interactions with its other receptor known as LTbR, translates into strong anti-tumor responses in checkpoint primary and acquired resistance murine tumor models, where TIGIT blocking antibodies demonstrate no activity.

TIGIT-Fc-LIGHT was evaluated and well tolerated in non-human primates at doses up to 40 mg/kg and similar on-target pharmacodynamic activity was observed to what was characterized preclinically in mice. Together, these results suggest that TIGIT-Fc-LIGHT may provide clinical benefit to patients that are refractory to conventional checkpoint blockade therapy.

Abstract title: Bispecific gamma/delta T cell engagers containing butyrophilin 2A1/3A1 heterodimeric fusion protein efficiently activate Vg9Vd2+ T cells and promote tumor cell killing

Shattuck presented preclinical data highlighting the potential of GADLENs to direct gamma delta T cells to kill tumor cells and in the process, further elucidate tumor cell markers which are important for the therapeutic activity of gamma delta T cell-based therapies.

Shattuck’s bispecific GADLENs containing heterodimeric BTN2A1 and BTN3A1 extracellular domains fused via inert Fc linkers to scFv domains, targeting CD19 or CD20 tumor-antigens, demonstrated an ability to induce proliferation, degranulation, and cytokine production in Vg9Vd2+ T cells with costimulation of a natural cytotoxicity receptor or T cell costimulatory receptor. Further, CD19 and CD20 directed GADLENs enhanced the specific killing of lymphoma cells that express both antigen targets.

RXC004, a highly potent and selective, orally active once-daily Porcupine inhibitor, is being developed as a targeted therapy for Wnt-ligand driven cancer. It is currently being evaluated as monotherapy in Phase 2 proof-of-concept clinical trials in genetically selected patients with pancreatic cancer and metastatic colorectal cancer and in unselected patients with biliary cancer. Additionally, RXC004 is in a Phase 1 combination study with nivolumab, an anti-PD-1 antibody from which a dose for the combination arm of the Phase will be selected this year. Data readouts from the Phase 2 studies are expected in 2023.

The poster presented at the AACR (Free AACR Whitepaper) meeting and entitled ‘Pre-clinical efficacy of the Wnt pathway inhibitor RXC004 in combination with anti-cancer therapies’ describes preclinical data which demonstrate that RXC004 in combination with clinically relevant standard of care chemotherapy regimens could lead to potential benefit, including survival, over chemotherapy alone. The poster hypothesised that the RXC004-induced downregulation of DNA repair pathway genes observed in vitro could contribute to the beneficial effect seen in combination with a PARP inhibitor in vitro as well as the combination effect observedin vivo with the standard of care chemotherapy agents.

D r Jane Robertson, Chief Medical Officer, Redx Pharma, said: "This preclinical data further underpins our excitement around the therapeutic potential of RXC004, and the role of effective Wnt pathway blockade, in tackling a number of difficult to treat cancers with high unmet need."

More information on the contents of the poster The presented poster, is available on the AACR (Free AACR Whitepaper) e-poster website and the investor section of the Company’s website at: View Source It describes how RXC004 was evaluated in a mouse colorectal xenograft model alone and in combination with both the FOLFIRI

* and FOLFIRINOX
** treatment regimens, currently both standard of care chemotherapy in colorectal cancer. Efficacy was measured by tumour volume and survival endpoint. In addition, RXC004 was studied in vitro, as monotherapy and in combination with a PARP inhibitor in genetically selected cell lines with both RSPO-fusion and RNF43 mutation. Combination and monotherapy effects on proliferation and effects on downstream signalling were investigated.

About RXC004
RXC004, a highly potent and selective, orally active once-daily Porcupine inhibitor is being developed as a targeted therapy for Wnt-ligand driven cancer. Aberrant Wnt signalling contributes directly to tumour growth and plays an important role in immune evasion, which has also been linked to resistance to immune-checkpoint inhibitors (ICIs) such as nivolumab. RXC004 has the potential to both directly inhibit the tumour growth and have an immune-enhancing effect in patients with tumours that have high Wnt-ligand dependency, such as tumours with mutations in the RNF43 gene and fusions in the RSPO gene family.

Immune checkpoint inhibitors (ICIs) such as anti-PD-1 antibodies have revolutionised the treatment of cancer, but do not work in all patients. Wnt pathway activation can enhance the ability of the tumour to evade destruction by the immune system and has been linked to lack of response to ICIs in these tumours. Our scientists have demonstrated preclinically that RXC004 can block activation of the Wnt pathway and restore the ability of the immune system to fight the tumour. Thus, RXC004 offers potential as a monotherapy or combination therapy.
