研究概览
简要总结
- PDOs are tridimensional multicellular structures expanded in vitro which retain the genotypic and phenotypic features of their tissue or tumor of origin. PDOs can be exposed to a panel of drugs (chemotherapy, hormonal therapy, targeted therapy) in order to study their sensitivity to each agent (or combination of agents) tested ('chemogram'). Recent studies showed that PDOs can accurately predict the response to treatment of solid tumors and could therefore inform clinical decision on the best therapeutic option for each patient.
- ORGANOTREAT is a multicenter prospective study program of organoid-based precision oncology encompassing 3 studies: ORGANOTREAT-01, a pilot study restricted to advanced CRC, and ORGANOTREAT-02A and -2B, two Phase 2 studies in advanced solid cancers.
详细描述
ORGANOTREAT-01, -02A and -02B
- Patients with advanced, pretreated solid cancers will be enrolled at the beginning of a standard-of-care (SoC) treatment line to allow sufficient time for PDO (tumor-derived organoid) generation and chemogram.
- A biopsy of an easily accessible tumor site will be performed.
- PDO generation, culture and amplification and drug testing will be performed.
- A chemogram report will be prepared.
- The CTB (Chemogram Tumor Board) will make treatment recommendations based on the chemogram report.
- Patients enrolled in ORGANOTREAT-01, ORGANOTREAT-02A and in the experimental arm of ORGANOTREAT-02B will be treated according to the CTB's recommendations after disease progression or unacceptable toxicity while on SoC.
- Patients will be treated at the investigator's discretion until disease progression or unacceptable toxicities. Patient will be followed until death or study termination, whichever occurs first . Note : Provide, as long as necessary (without time limit) the treatments to patient is agreed by all the centers.
- Patients for whom no chemogram can be obtained will be treated according to Soc

研究组 & 干预措施
ORGANOTREAT 01
To assess the feasibility of timely generating chemograms from PDOs in advanced CRC.
To assess the proportion of patients treated according to the chemogram tumor board (CTB)'s recommendations on the basis of their personalized chemogram.
To assess the efficacy and safety of chemogram-driven treatment in advanced CRC.
干预措施: Biopsy (Procedure)
ORGANOTREAT 02A
ORGANOTREAT-02A is a single-arm, Phase II study to evaluate the feasibility of chemogram-driven treatment in patients with advanced, pretreated solid cancers (CRC or PDAC). The primary endpoint is to assess the proportion of patients treated according to the chemogram tumor board (CTB)'s recommendations on the basis of their personalized chemogram.
干预措施: Biopsy (Procedure)
ORGANOTREAT 02B
is a randomized Phase II study to compare the efficacy of chemogram-driven treatment vs SoC in patients with advanced, pretreated solid cancers with a PDO take-on rate ≥50%. A cross-over will allow patients enrolled in the control arm to benefit from chemogram-based treatment. Patients for whom no chemogram can be obtained will not be randomized and they will be treated according to SoC. The primary endpoint will be PFS. The study will include multiple strata, each for a different tumor type (e.g., stratum 1, pancreatic ductal adenocarcinoma (PDAC); stratum 2, CRC; etc.). Each stratum will be conducted and analyzed independently from the other strata.
