Pear Bio has developed an organ-on-a-chip device together with a computer vision pipeline through which the response of an individual patient's tumor to different systemic therapy regimens can be tested simultaneously ex vivo. This study will recruit patients with advanced or metastatic triple negative breast cancer who are due to start a clinically-indicated new line of therapy.

The oncologist will be blinded to the response on the Pear Bio tool (the assay will be run in parallel with the patient's treatment). The primary objective of this study is to establish the sensitivity and specificity of Pear Bio's test against patient outcomes (response, progression-free survival, overall survival)

This is a UK-based observational study that aims to discover novel predictive biomarkers with the potential to guide treatment decision making and prolong PFS and OS in patients with advanced TNBC. Patients will undergo a mandatory, study-specific core needle biopsy or fine needle aspiration of the breast tumour or metastasis before commencing their next line of therapy. The research sample will be run on Pear Bio's test whilst the patient receives therapy as per their physician's choice. This study will not use Pear Bio's tool to inform the choice of treatment, with the treating oncologist being blinded to the test results. Treatment response data will be collected at multiple timepoints to conduct analyses on the study's secondary and tertiary objectives.

Fresh tissue resections that arrive at Pear Bio's lab will undergo processing, cell culture and various drug dosing and omics assays (depending on extracted cell numbers). Tumour samples will be processed using a cell isolation kit to retrieve a viable single-cell suspension. A minimum of 100,000 cells (10,000 viable cells per chip) will be used for staining with live and dead cell-tracking dyes. In parallel, blood vials will be processed for PBMCs and further effector cell extraction (flow cytometry, Dynabeads, etc). The remaining cells will be used for sequencing (DNA/RNA), fixed for immunofluorescence characterisation of biomarkers/receptor status or used for further omics assays (if cell numbers allow). This may include tumour mutational burden and microsatellite instability testing.

The stained cells will be cultured in a biomimetic hydrogel within Pear Bio's organ-on-a-chip to provide a physiological 3D environment for drug dosing experiments. Using a microfluidic device, samples in each chip will be exposed to approved therapies (either as monotherapy or combination therapies, as outlined below) over multiple days.

In parallel, PBMCs will be extracted from whole blood, characterised and sorted via flow cytometry and fluorescence-activated cell sorting (FACS) or magnetic beads selection. Cells of interest (e.g. CD8+ T cells) will be used for culture in Pear Bio's chips jointly with cells isolated from the matched tumour sample. To test immunotherapies, tumour cells will be co-cultured with immune cells in a modified organ-on-a-chip architecture. Chips receiving immunotherapies may be tested for tumour mutational burden and/or microsatellite instability.

Confocal microscopy will be conducted daily to collect 3D image data of the cells and track their position and behaviour over time. At the end of the assay, the 3D cell cultures will be fixed for further 3D immunofluorescence analyses or used for embedding, sectioning and assessment of spatial transcriptomics. For targeted therapies, RNAseq, IF and other omics data will be integrated to confirm drug MoA and identify other potential therapeutic targets. Concurrently, 3D image data is processed through a computer vision pipeline to measure functional metrics of the ex vivo 3D cell cultures, including cell viability, cell culture width and cell migration, both at a bulk tumour level and at a single-cell resolution. For immunotherapies, additional metrics such as immune cell infiltration and immune cell killing will be recorded. A patient report is then generated to outline an individual patient sample's response to each therapy tested.

Pear Bio has developed an organ-on-a-chip device together with a computer vision pipeline through which the response of an individual patient's tumor to different chemotherapy regimens can be tested simultaneously ex vivo. This study will recruit patients with early TNBC who are planned for standard of care neoadjuvant chemotherapy followed by surgery. The oncologist will be blinded to the response on the Pear Bio tool (the assay will be run in parallel with the patient's neoadjuvant chemotherapy). The primary objective of this study is to establish the sensitivity and specificity of Pear Bio's test against patient outcomes (pathological complete response).

This is a multicenter, UK-based, observational pilot study that aims to determine the accuracy of a new assay, the Pear Bio tool, in predicting pathological complete response (pCR) in patients receiving neoadjuvant chemotherapy for early TNBC. Patients will undergo an additional, mandatory biopsy of the breast tumor before commencing neoadjuvant chemotherapy. The biopsy sample will be run on the Pear Bio tool while the patient receives their standard of care neoadjuvant chemotherapy. As such, for this study, the result from the Pear Bio tool will not be used to inform the choice of neoadjuvant chemotherapy and the treating oncologist will be blinded to the assay results. The pathological outcome from surgery (pCR vs non-pCR) will be collected and used to calculate the specificity of the assay as the primary endpoint of the study. Sensitivity, positive predictive value and negative predictive value will also be measured.

Pear Bio has developed a 3D microtumor assay and computer vision pipeline through which the response of an individual patient's tumor to different anti-cancer regimens can be tested simultaneously ex vivo. This study will recruit patients with primary brain tumors who are due to undergo surgery.

Oncologists will be blinded to treatment response on the Pear Bio tool (the assay will be run in parallel with the patient's treatment). The primary objective of this study is to establish the ex vivo model and confirm whether approved therapies exhibit their intended mechanism of action in the model. Secondary objectives include correlating test results to patient outcomes, where available.

This is a multicenter, observational pilot study that aims to determine the feasibility of using the Pear Bio tool in patients with primary solid brain tumors.

Patients who are due to undergo clinically-mandated surgery will provide informed consent to donate excess tissue and a 40mL blood sample.

The samples will be tested on the Pear Bio tool while the patient receives their standard of care treatment. As such, for this study, the result from the Pear Bio tool will not be used to inform the choice of treatment and the treating oncologist will be blinded to the assay results.

The investigators will examine drug mechanism of action (MoA), differentiated response, and correlate that with outcomes seen in the patients treated in routine clinical practice.

in Group 3D, an intrafascial nerve-sparing (NS) technique will be performed on the side of the lesion; contralaterally an intra-, inter- or extra-fascial NS technique will be performed. After removal of the prostate, virtual images of the prostate will be projected into the lodge using AI software and will be displayed thanks to the Tile-Pro. The virtual 3D model will allow identifying the extracapsular extension of the tumor lesion, projected at the level of the preserved neurovascular bundle.

A first selective excisional biopsy at the level of the suspected ECE on the NVB will be sent for extemporaneous histological examination. Under 3D AR guidance, a second selective biopsy will then be performed on the NVB at the same level as the first, however involving a larger and thicker layer of tissue. the biopsies will be sent for extemporaneous histological examination. In case of positivity, the entire NVB will be removed

For the no-3D group, the intra-, inter- or extra-fascial NS technique during robotic prostatectomy will be performed according to the clinical indication.

At the end of the demolitive phase a selective biopsu was performed in a cognitive fashion accordin with the information provided by MRI images.

Reconstructive phase was performed according to our previously described total anatomical reconstruction (TAR) technique for both arms.

The operation is performed using the "Da Vinci HD" robotic system which allows the use of laparoscopic instruments, with greater mobility and the possibility of easier and more precise control of movements in three dimensions. Furthermore, the system allows the surgeon a three-dimensional view of the operating field. The surgery is performed under general anesthesia. Six or more trocars are positioned, into which the instruments operated by the robot or directly by the surgical assistants are inserted.

Then a radical prostatectomy is performed.

This is a prospective randomized multicenter study aimed at comparing 3D AI-AR-RARP vs. no 3D, verifying the impact of this new technology on oncological and functional outcomes after the procedure.

Considering that prostate cancer lesions are not identifiable during surgery, except in the case of extensive and advanced tumors, the surgeon does not have a real-time perception of the location of the tumor. The absence of clear spatial visualization can therefore lead to a positive surgical margin, particularly in tumors in the T3 stage (invasion of the prostatic capsule or seminal vesicles).

Our hypothesis is that with the help of AI 3D AR during surgery, positive surgical margins can be avoided, or at least reduced, while preserving the neurovascular bundles, with a consequent improvement not only in postoperative functional outcomes (continence and potency), but also oncological ones (less biochemical disease recovery (BCR), less need for salvage radiotherapy, lower risk of metastasis).

Patients will be randomized using an Excel® macro in 2 group: 3D and no3D, stratifying them by age, PSA, cT, PSA density, prostate volume, lesion volume, extracapsular extension (ECE), seminal vesicle invasion (SVI), biopsy ISUP.
