A Multicenter, Prospective Single-arm Study of Multimodal Thermal Therapy Combined With Toripalimab and AG Chemotherapy in the Treatment of Advanced Pancreatic Cancer (SMP1-13115)

5 de noviembre de 2026 actualizado por: Ruijin Hospital

This study is a multicenter, prospective, single-arm, open-label, Simon two-stage phase II clinical trial designed to evaluate the conversion therapeutic value of multimodal thermal therapy combined with TIS (Toripalimab) and AG chemotherapy (gemcitabine plus nab-paclitaxel) in previously untreated metastatic pancreatic cancer patients with liver-only or lung-only metastases.

  • 5. Suffering from any disease requiring systemic treatment with corticosteroids (prednisone or equivalent at a daily dose >10 mg) or other immunosuppressive drugs within 14 days prior to enrollment;
  • 6. Previous or current diagnosis of brain metastases with symptoms not fully controlled (i.e., persistent or worsening symptoms, or requiring adjustment of symptomatic treatment to maintain symptom relief);
  • 7. Uncontrolled active infection;
  • 8. Renal dysfunction: serum creatinine >176.8 μmol/L or creatinine clearance <30 ml/min;
  • 9. Uncorrectable abnormal coagulation function: platelet count <50×10⁹/L, prothrombin time >18 s, prothrombin activity <40%, and uncorrectable;
  • 10. History of ruptured esophagogastric varices that have not been effectively treated by endoscopy, interventional therapy, or surgery;
  • 11. Patients with psychiatric disorders in the active phase;
  • 12. Pregnant or lactating women, or women of childbearing age who plan to become pregnant within 3 months after the end of study treatment;
  • 13. Expected survival <3 months;
  • 14. Any other factors that the investigator deems unsuitable for inclusion or that may affect the subject's participation in the study.

multimodal thermal therapy combined with TIS (Toripalimab) and AG chemotherapy (gemcitabine plus nab-paclitaxel)

The MTT system is a medical device that performs sequential ablation therapy. Treatment consists of initial cryoablation followed immediately by radiofrequency ablation (RFA) to achieve a synergistic thermal effect against the tumor.

Toripalimab is a humanized IgG4 monoclonal antibody against programmed death-1 (PD-1). It is administered via intravenous infusion at a standard dose according to the protocol to block the PD-1/PD-L1 pathway and enhance anti-tumor immunity.

Gemcitabine combined with nab-paclitaxel (albumin-bound paclitaxel) is a standard chemotherapy regimen for advanced pancreatic cancer. Both drugs are administered via intravenous infusion according to the clinical protocol to inhibit cancer cell proliferation and division.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Conversion success rate
Periodo de tiempo: From the start of treatment (Multimodal Thermal Therapy) until the evaluation of surgical conversion following at least 4 cycles of subsequent combination therapy, assessed up to 2 years

Percentage of subjects achieving successful conversion among all enrolled subjects

From the start of treatment (Multimodal Thermal Therapy) until the evaluation of surgical conversion following at least 4 cycles of subsequent combination therapy, assessed up to 2 years

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Progression-Free Survival(RECIST 1.1)
Periodo de tiempo: From the start of treatment until documented disease progression or death, assessed up to 2 years

Time from the start of treatment until disease progression (according to RECIST 1.1 based on enhanced abdominal/chest-abnormal CT or MRI every 6-8 weeks) or death from any cause, whichever occurs first.

From the start of treatment until documented disease progression or death, assessed up to 2 years
Recurrence-Free Survival
Periodo de tiempo: From the date of radical surgical resection until disease recurrence or death from any cause, assessed up to 2 years

From the date of radical surgical resection to the first confirmed disease recurrence by imaging or pathology, or death from any cause, whichever occurs first. Disease recurrence, including local recurrence and distant metastasis, is assessed by imaging examinations (CT/MRI ± PET-CT) or confirmed by histopathological evidence. For patients without recurrence, follow-up data will be censored at the date of the last disease assessment.

From the date of radical surgical resection until disease recurrence or death from any cause, assessed up to 2 years
Overall Survival
Periodo de tiempo: up to approximately 24 months

Time from the date of first study intervention to the date of death from any cause or the date of the last confirmed survival follow-up. Long-term survival will be tracked through regular follow-up visits until death, loss to follow-up, or study termination.

up to approximately 24 months
Objective Response Rate
Periodo de tiempo: up to approximately 24 months

Imageological evaluation was conducted according to the RECIST 1.1 criteria for solid tumors. Target lesions included both the primary pancreatic tumor in situ and measurable metastatic lesions in the liver or lungs. Quantitative measurement of the longest diameter of each target lesion was performed using contrast-enhanced CT or MRI, and the sum of the longest diameters was calculated to determine the change, thereby assessing tumor response.

up to approximately 24 months
Incidence of Adverse Events
Periodo de tiempo: From the first study intervention until 30 days after the last treatment or up to 24 months

The incidence, severity, and type of adverse events (AEs) and serious adverse events (SAEs) evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE v6.0), as well as changes in laboratory tests, vital signs, and physical examinations.

From the first study intervention until 30 days after the last treatment or up to 24 months
