Study Description

Brief Summary:

This is an open-label, non-randomized, single-arm phase Ⅱ study aiming to evaluate the efficacy and safety profile of above-mentioned combination strategy in first-line therapy-failed advanced pancreatic cancer. Totally 53 patients with locally advanced or metastatic pancreatic cancer are to be enrolled and receive anlotinib plus toripalimab and nab-paclitaxel.

Condition or disease	Intervention/treatment	Phase
Pancreatic Neoplasm; Metastatic Pancreatic Cancer; Locally Advanced Pancreatic Adenocarcinoma	Drug: Anlotinib+Toripalimab+Nab-paclitaxel	Phase 2

Detailed Description:

Anlotinib Hydrochloride Capsules (12 mg orally, once daily before breakfast; CTTQ, Lianyungang, Jiangsu, China), Toripalimab (240 mg intravenously, once every 3 weeks; Shanghai Junshi Biosciences Co., Ltd., Shanghai, China) and Nab-paclitaxel (125 mg/m2 intravenously, twice every 3 weeks; CSPC, Shijiazhuang, Hebei, China) are to be administered as a second-line therapy at most 6 cycles. Patients assessing as CR/PR/SD continue to receive a maintenance treatment including anlotinib and toripalimab until disease progression, intolerable toxicity, patient request for discontinuation for up to two years.

Observations and assessments will be conducted before treatment, on day 7, 21 of cycle 1, on day 21 of cycle 2, every 2 cycles (42 days) during following cycles and after treatment. Follow-up for survival status and subsequent antineoplastic therapy data collecting will be performed by telephone interview or face-to-face every 6 weeks after treatment until disease progression, death or end of the study (whichever occurs first).

Using 2.9 months served as a control, the expected median PFS of patients treated with anlotinib plus toripalimab and nab-paclitaxel in this study is prespecified as 4.5 months. Significance level α=0.05 (two-tailed) and test power (1-β)=0.80 are used for sample size calculation by PASS (Power Analysis and Sample Size) software. Taking a 20% drop-out rate into consideration, the sample size is approximately 53 patients. An interim analysis will be performed using a Lan-DeMets Pocock type boundary to assess the futility and efficacy when approximately half of the predetermined sample size is allocated. If the interim analysis results indicate that the study is of futility and the benefit/risk ratio is significantly worse, the trial will be terminated by the investigators. Otherwise, the trial will continue until the full sample size of 53 has been accumulated.

Efficacy is to be analyzed in the full analysis set (FAS), the response evaluable set (RES) and per-protocol set (PPS). Safety is to be analyzed in safety set (SS) including all assigned patients who receive at least one dose of study combined therapy and have safety records of medication. Statistical descriptions of subject distribution, demographic data and baseline characteristics will be performed. For study endpoints, the Kaplan-Meier method is to be applied for the PFS and OS curve with estimation for median PFS, median OS and 95% CI. ORR= (CR+PR) / sample size×100%; DCR= (CR+PR+SD) / sample size×100%. The 95% CI of the ORR and DCR are to be calculated by exact binomial method based on the F distribution. ECOG PS scores and QoL scores will be described at each visit time. For safety analysis, only treatment emergent adverse event (TEAE) will be included and analyzed in this experiment, which is defined as AEs that are post-dose or heavier than the baseline. Medical Dictionary for Regulatory Activities (MedDRA), system organ class (SOC), preferred terms (PT) and NCI CTCAE 5.0 will be used to standardize and classify all adverse events and summarize the incidence of AEs and association with treatments. Vital signs, ECG, and laboratory evaluation results will be compared and analyzed before and after treatment.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Experimental Group; Patients who failed first-line therapy with locally advanced or metastatic pancreatic cancer will be assigned to receive anlotinib plus toripalimab and nab-paclitaxel as second-line or maintenance treatment.	Drug: Anlotinib+Toripalimab+Nab-paclitaxel; Using combination treatment of anlotinib (12 mg, po. qd.) plus toripalimab (240 mg, ivgtt. q3w.) and nab-paclitaxel (260 mg/m2, ivgtt, q3w) with every 3 weeks as a cycle.; Other Name: combination therapy

Outcome Measures

Primary Outcome Measures :

1. Progression-free survival (PFS) [ Time Frame: Up to 24 months. ]
   From allocation to first disease progression confirmed by imaging modalities or all cause death, whichever occurs first.

Secondary Outcome Measures :

1. Overall survival (OS) [ Time Frame: Up to 24 months. ]
   From allocation to any cause death or last follow-up.
2. Object response rate (ORR) [ Time Frame: Up to 24 moths. ]
   Containing the incidence of complete response (CR) and partial response (PR).
3. Disease control rate (DCR) [ Time Frame: Up to 24 months. ]
   Containing the incidence of complete response (CR), partial response (PR) and stable disease (SD).
4. Quality of life (QoL) [ Time Frame: up to 24 months. ]
   QoL refers to EORTC QLQ-C30 (version 3, Chinese version), and will be recorded in case report form (CRF) by observing clinical symptoms and scoring related examination before and after study treatment.
5. The incidence and severity of adverse events (AEs) and severe adverse events (SAEs) [ Time Frame: Up to 24 months. ]
   AEs and SAEs will be graded and recorded according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC, version 4.0). AEs are defined as any adverse medical events that occur in subjects from initiation of allocation up to 30 days after the last administration. SAEs are defined as all adverse medical events at any drug dose that result in a fatal, life-threatening event or prolonged hospital stay, permanent disability or other important medical conditions.
