结局指标
主要结局
Safety and tolerability of THEO-260 [Part A]
时间窗: Until Day 28 after first dose
Assessment of DLTs and AEs during treatment and follow-up using NCI CTCAE v5.0 or ASCO (for pneumonitis only) or ASTCT (for CRS only), plus Laboratory parameters and clinical safety assessments.
Establish recommended Phase 2 dose (RP2D) for THEO-260 [Part A]
时间窗: Estimated at 2 years
Determination of RP2D will be based on the totality of safety, PK and preliminary efficacy data
Evaluate preliminary efficacy of THEO-260 [Part B]
时间窗: Estimated at 16 weeks
Determine tumour response by RECIST v1.1 and iRECIST and changes in CA-125.
Safety and tolerability of THEO-260
时间窗: Until end of trial for a participant, estimated at 1 year
Safety and tolerability will be assessed by: Evaluation of DLTs and AEs during treatment and follow-up using National Cancer Institute (NCI) Common Terminology Criteria for AEs (CTCAE) v5.0 or American Society of Clinical Oncology (ASCO; for pneumonitis only) or American Society for Transplantation and Cellular Therapy (ASTCT; for cytokine release syndrome \[CRS\] only).
Establish recommended Phase 2 dose (RP2D) for THEO-260
时间窗: Until end of Part A of trial, estimated at 18 months after start of enrolment
The totality of safety and efficacy data collected will be used to assess RP2D.
Evaluate preliminary efficacy of THEO-260
时间窗: Until end of trial, estimated at 3 years after start of enrolment
The response to RP2D dose of THEO-260 will be assessed by Overall Response Rate (ORR) determined by tumour imaging according to RECIST v1.1.
次要结局
- Pharmacokinetic (PK) profile of THEO-260(Until Day 29 after first dose)
- Shedding of THEO-260 in saliva, urine and faeces(Until Day 29 after first dose)
- Risk of systemic cytokine release syndrome (CRS) after THEO-260(Until Day 29 after first dose)
- Evaluate preliminary efficacy of THEO-260 - RECIST(Until end of trial, estimated at 3 years after start of enrolment)
- Evaluate preliminary efficacy of THEO-260 - CA125(Until end of trial, estimated at 3 years after start of enrolment)
- Pharmacokinetics (PK) of THEO-260(Estimated at 16 weeks)
- Shedding of THEO-260(Until Day 29 after first dose)
- Systemic CRS risk after THEO-260(Until Day 29 after first dose)
- Preliminary efficacy of THEO-260 [Part A](Estimated at 16 weeks)

Theolytics Secures €8 Million EU Grant to Advance Novel Oncolytic Immunotherapy for Platinum-Resistant Ovarian Cancer- Theolytics has been awarded €8 million in non-dilutive grant funding from Horizon Europe 2025 to advance its Phase 2 OCTOPOD-IV clinical trial of THEO-260 in platinum-resistant ovarian cancer.
- THEO-260 is a novel oncolytic immunotherapy designed to kill both cancer cells and cancer-associated fibroblasts while inducing immune activation in stroma-rich solid tumors.
- The competitive funding award validates the company's innovative approach to addressing significant unmet medical needs in patients with advanced ovarian cancer, whose life expectancy is typically one year or less.
- The grant will support up to 20 patients in the Phase 2a expansion study and involves major international clinical centers including institutions in Spain, Canada, and the UK.6 months agoTheolytics Advances Novel Oncolytic Immunotherapy THEO-260 in Phase I/IIa Ovarian Cancer Trial- Theolytics is presenting data from the ongoing OCTOPOD-IV Phase I/IIa trial of THEO-260, a novel oncolytic immunotherapy targeting cancer cells and cancer-associated fibroblasts in ovarian cancer patients.
- The first-in-human trial evaluates intravenous delivery of THEO-260 in patients with high-grade serous or endometrioid ovarian cancer, with recruitment ongoing at UK sites and international expansion planned.
- A second US trial (OCTOPOD-IP) investigating intraperitoneal delivery has been initiated in collaboration with MD Anderson Cancer Center, addressing the significant unmet need in platinum-resistant ovarian cancer.
- THEO-260's differentiated mechanism targets the stromal-rich tumor microenvironment, where cancer-associated fibroblasts can comprise up to 60% of tumor volume in ovarian cancer.11 months agoTheolytics Doses First Patient in Phase I/IIa Trial of THEO-260 for Ovarian Cancer- Theolytics has initiated a Phase I/IIa trial (OCTOPOD) of THEO-260, an oncolytic immunotherapy, in patients with advanced platinum-resistant ovarian cancer (PROC).
- THEO-260 is designed to lyse cancer cells and cancer-associated fibroblasts (CAFs) while alleviating immune suppression within the tumor microenvironment.
- The trial aims to assess the safety, tolerability, and recommended Phase 2 dose of intravenously administered THEO-260, with comprehensive biomarker analysis planned.
- Preclinical data suggest THEO-260 can trigger immunogenic cell death and promote T-cell activation, offering a differentiated approach for treating ovarian cancer.last yearTheolytics Doses First Patient in Phase I/IIa Trial of THEO-260 for Ovarian Cancer- Theolytics has initiated a Phase I/IIa trial of THEO-260, an oncolytic immunotherapy, in patients with advanced-stage platinum-resistant ovarian cancer (PROC).
- THEO-260 targets both cancer cells and cancer-associated fibroblasts, aiming to overcome the immune-suppressed tumor microenvironment in ovarian cancer.
