PaC: Advanced Pancreatic Cancer
Study Details
Study Description
Brief Summary
This study is a single-arm, open, single-center clinical study to observe and evaluate the efficacy and safety of sovalteinib in combination with solutumab and tegeo in second-line and post-line treatment of patients with advanced pancreatic cancer.
A total of 30 patients were enrolled in this study, which was divided into 3 phases:
screening phase, treatment phase and follow-up phase. During the treatment period, tumor status was evaluated by imaging methods every 6 weeks (±7 days) until disease progression (PD, RECIST 1.1) or death (during patient treatment) or intolerable toxicity, and tumor treatment and survival status after disease progression were recorded. Safety observations included AE, changes in laboratory test values, vital signs, and changes in ECG. In addition, 10 ml of blood was drawn for testing in our laboratory before each treatment and at the time of disease progression before the patients were enrolled, and the exploration of the efficacy-related biomarker BRCA1 was performed by blood samples.

| Experimental: Prospective Research Soventinib in combination with solutumab and tegeo dosing regimen: Soventinib: 200 mg orally, within 1 hour of breakfast, administered once daily as a continuous dose, d1-d21, every 3 weeks in treatment cycles Slulizumab: 300 mg administered intravenously, d1, every 3 weeks for one treatment cycle. Tegeo: 40-60 mg/dose administered twice daily, d1-d14, continuously (dosing based on body surface area (BSA): 40 mg/dose for BSA ≤ 1.25 m2; 50 mg/dose for 1.25 ≤ BSA < 1.5 m2 and 60 mg/dose for BSA ≥ 1.5 m2), every 3 weeks for one treatment cycle. Dose adjustments, including suspension, dose reduction, or permanent discontinuation, were allowed as required by the protocol. |

Outcome Measures
Primary Outcome Measures
- PFS [through disease progression, an average of 6 months]
Time between the start of treatment and the onset of (any aspect of) progression of the tumor or death (from any cause)
Secondary Outcome Measures
- ORR [through disease progression, an average of 6 months]
The proportion of patients whose tumor volume shrinks to a pre-specified value and who can maintain the minimum time requirement is the sum of the proportion in complete and partial remission.
- DCR [through disease progression, an average of 6 months]
The number of cases that achieved remission (PR+CR) and stable lesions (SD) after treatment as a percentage of the evaluable cases.
- OS [through patients' death, an average of 12 months]
Time from start of treatment to death (from any cause)
