HNSCC patients presenting with a surface accessible lesion who are scheduled for tumor and/or regional node dissection as part of their standard treatment will be injected one to three days prior to surgery using the CIVO device. The planned injection scheme includes: vehicle control and microdoses of rilvegostomig, volrustomig, sabestomig, and pembrolizumab alone.

This is a multi-center, open-label, Phase 0 substudy designed to evaluate the localized pharmacodynamics (PD) of rilvegostomig, volrustomig, and sabestomig within the tumor microenvironment (TME) when administered intratumorally in microdose quantities via the CIVO device in patients presenting with Head and Neck Squamous Cell Carcinoma (HNSCC) with a surface accessible lesion, who are scheduled for tumor and/or regional node dissection as part of their standard treatment. PD effects due to injected investigational agents will be compared to those elicited by pembrolizumab alone, which will also be injected in microdose quantities via the CIVO device.

The CIVO Microdose Injection Device (MID) simultaneously delivers multiple drugs and drug combinations (Up to 8), each in microdose amounts, into a single patient tumor and enables comparisons of the resulting biomarker responses that occurred while that tumor was still in the native microenvironment. AstraZeneca is developing three novel assets: rilvegostomig, volrustomig, and sabestomig, all of which are bispecific monoclonal antibodies designed to stimulate antitumor immunity. In this Phase 0 clinical trial, the PD effects of these investigational assets in the TME of patients presenting with HNSCC will be evaluated. These investigational assets will be injected alone in microdose quantities at tumor sites in HNSCC patients. Pembrolizumab, also used therapeutically in this patient population, will be included in the CIVO injection array administered as a single agent. The CIVO-injected portion of the tissue will be analyzed for localized response at sites of drug exposure in the TME.

This is an exploratory clinical trial to evaluate intratumoral mechanistic effects of novel and approved agents on intact human tumors. This is a cohort substudy of a Master Protocol (PBI-MST-01, NCT04541108) framework, under which comparisons will not be made between substudy cohorts.

A Phase 0 Multicenter Study of the Pharmacodynamic Effects of Intratumoral Microdose Administration of Rilvegostomig, Volrustomig, and Sabestomig

The localized activity of injected microdoses will be analyzed using the NanoString GeoMx Digital Spatial Profiler (DSP) and the GeoMx Cancer Transcriptome Atlas to comprehensively profile over 1800 genes simultaneously with spatial resolution to describe tumor biology, the TME, and the immune response signatures of each drug at an injection site. DSP outcomes may be validated via IHC or ISH technique.

Safety of the microdose injection procedure and injected content will be assessed by quantification of the frequency, intensity, and relatedness of all reported Adverse Events and/or Adverse Device Effects.

Patients who are scheduled for surgical biopsy or tumor resection surgery will be injected at least four hours to up to four days prior to surgery using the CIVO device. Each needle of the CIVO device will deliver up to 8.3 microliters of solution, including a vehicle control (sterile saline) or subtherapeutic microdoses of TAK-676, carboplatin, 5-fluorouracil (5- FU), or paclitaxel as single agents or in combination. Each microdose is simultaneously injected in a columnar fashion through each of 8, 5, or 3 needles (in a device configuration determined by tumor dimensions) into a single solid tumor or effaced metastatic lymph node.

This is a multi-center, open-label Phase 0 substudy designed to study the localized pharmacodynamics (PD) of TAK-676 alone or in combination with Carboplatin, 5-FU, or Paclitaxel within the tumor microenvironment (TME) when administered intratumorally in microdose quantities via the CIVO device in patients diagnosed with Head and Neck Squamous Cell Carcinoma presenting with a surface accessible solid tumor for which there is a scheduled surgical intervention. This substudy is a cohort of the PBI-MST-01 Master Protocol.

CIVO is a research tool composed of a hand-held single-use sterile injector coupled with fluorescent tracking microspheres called CIVO GLO that mark the sites of drug microdose injection, enabling rapid assessment of multiple oncology drugs or drug combinations simultaneously within a patient's tumor. Tumor responses to cancer treatments are highly context-specific and often involve complex interactions between the anti-cancer therapy, genetically diverse tumor cells, and a heterogeneous TME. This complexity is rarely modeled accurately in preclinical translational models of cancer.

In this Phase 0 intratumoral microdosing substudy in human patients with Head and Neck Squamous Cell Carcinoma (who will be undergoing previously planned tumor and/or regional node dissection), we will evaluate the ability of TAK-676 to activate innate immune effector cells within the local tumor microenvironment. Additionally, this study will examine the effect of TAK-676 in combination with Carboplatin, or Paclitaxel, or in combination with 2 agents Carboplatin and 5-FU, or Carboplatin and Paclitaxel to study whether TAK-676 enhances the localized immune responses compared to both immunotherapy combinations or Carboplatin alone. All investigational drug combinations will be delivered intratumorally in subtherapeutic microdose quantities via the CIVO platform.

The CIVO Microdose Injection Device (MID) penetrates solid tumors and delivers subtherapeutic microdoses of up to eight anti-cancer agents, or combinations of anti-cancer agents, co-injected with CIVO GLO into discrete regions of the tumor. At the time of the planned surgical intervention (4 hours up to four days after the CIVO microdose injection), the injected tumor tissue is then excised and tumor responses are assessed via histological staining of tumor cross-sections sampled perpendicular to each injection column. Co-injection with CIVO GLO enables identification of each injection site during resection as well as in tissues stained for biomarker analysis. Because the platform delivers microdose amounts of each test agent, or combination, directly into the patient's tumor tissue, mechanistic hypotheses can be tested early in the drug development process, consistent with the goals of the 2006 FDA Exploratory Investigational New Drug (IND) Guidance for Industry.

This is an exploratory clinical trial to evaluate intratumoral mechanistic effects of novel and approved agents on intact human tumors. This substudy is not blinded. This is a cohort substudy of a Master Protocol (PBI-MST-01, NCT 04541108) framework that describes the experimental workflow for use of the CIVO platform. Comparisons will not be made between substudy cohorts.

TAK-676 Alone and in Combination(s) With Carboplatin, 5-Fluorouracil, and Paclitaxel in Patients With Head and Neck Squamous Cell Carcinoma

Quantification of biomarker-positive and biomarker-negative cells will be performed within the tumor microenvironment around each of the injection sites in each resected patient sample by IHC and ISH. An aggregate analysis of this quantification may be done across patient samples in each substudy to evaluate trends in tumor response. The biomarkers evaluated may include, but are not limited to, biomarkers for cell death (e.g., cleaved caspase 3), T-cells (e.g., Cluster of Differentiation 3 (CD3), Cluster of Differentiation 8/Granzyme B, Cluster of Differentiation), natural killer (NK)/myeloid cells (e.g., Cluster of Differentiation 56/Granzyme B, Cluster of Differentiation 86, Cluster of Differentiation 68, Cluster of Differentiation 163), and proinflammatory cytokines (e.g., interferon gamma, tumor necrosis factor alpha, interferon gamma-induced protein 10).

Relationship of adverse event (AE) to study drug(s) or CIVO device will be determined using an AE Relatedness Grading System
