Brief summary

Primary Objective Dose Escalation: To evaluate the safety and tolerability of surufatinib in patients with advanced solid tumors and to determine the maximum tolerable dose (MTD) or recommended phase II dose (RP2D). Primary Objective Dose Expansion: To evaluate the anticancer activity of surufatinib in patients with advanced Biliary Tract Cancer (BTC), patients with advanced pancreatic neuroendocrine tumors (pNETs), patients with locally advanced, unresectable, metastatic extra-pancreatic neuroendocrine tumors (EP-NETs), and patients with soft tissue sarcomas (STS) treated at a dose of 300 mg QD. Secondary Objective: To evaluate the pharmacokinetic profile of multiple dose surufatinib in patients with advanced solid tumors and to evaluate the anti cancer activity of surufatinib in patients with advanced solid tumors.

Detailed description

The study is an open-label, dose escalation and expansion clinical trial of surufatinib orally once daily (QD) in patients with advanced solid tumors. The study consists of two phases: Dose escalation phase - A 3+3 design will be used for this portion of the study. * Approximately 15 to 35 evaluable patients will be enrolled. The actual number of patients depends on the Dose-limiting toxicity (DLT) situation as well as the RP2D dose level reached in this trial. * The trial will approximately evaluate five surufatinib dose levels at 50,100, 200, 300 and 400 mg/day. Expansion phase: Approximately 115 patients will be enrolled into one of four open-label treatment arms during this phase: at least 30 patients with advanced BTC that has progressed on standard first-line chemotherapy will be assigned to Arm A, at least 15 patients with advanced pNET that has progressed on either everolimus, sunitinib, or both will be assigned to Arm B, at least 15 patients with advanced EP-NET that has progressed on everolimus will be assigned to Arm C, and at least 45 patients with Soft Tissue Sarcoma will be assigned to Arm D. Subjects enrolled in this phase are to be evaluated for the safety, tolerability and pharmacokinetic (PK) characteristics to confirm the selected surufatinib dose. Subjects will receive surufatinib daily treatment continuously with every 28-day treatment cycle until disease progression, death, or intolerable toxicity at the investigator's discretion for a favorable benefit to risk balance.

An SAE was an AE that resulted in any of the following outcomes: was fatal; was life threatening; required or prolonged inpatient hospitalization; resulted in persistent or significant disability/incapacity; a congenital anomaly/birth defect in a neonate/infant born to a female patient or female partner of a male patient exposed to the study drug(s); was considered a significant medical event by the Investigator. TEAEs were defined as any AEs that started or worsened in severity on or after the first administration date of study drug and no later than 30 (+7) days after the last administration date of study drug or initiation of new anti-tumor therapy (whichever occurred first).
Dose-Expansion Phase: Arms A and D: Progression Free Survival (PFS) Rate at 16 WeeksAt 16 weeksThe tumor response was determined according to the international Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 guideline. PFS is defined as the time (in months) from the start date of study medication (Day 1) until the date of objective disease progression as defined by RECIST Version 1.1 or death (by any cause in the absence of progression), whichever occurred earlier. PFS rate probability at 16 week was estimated. Progression is defined by RECIST v1.0 as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (nadir), including baseline or appearance of 1 or more new lesions.
Dose-Expansion Phase: Arms B and C: PFS Rate at 11 MonthsAt 11 monthsThe tumor response was determined according to the RECIST v1.1 guideline. PFS is defined as the time (in months) from the start date of study medication (Day 1) until the date of objective disease progression as defined by RECIST Version 1.1 or death (by any cause in the absence of progression), whichever occurred earlier. PFS rate probability at 11 months was estimated. Progression is defined by RECIST v1.0 as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (nadir), including baseline or appearance of 1 or more new lesions.

The CR was defined as disappearance of all target lesions. The PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum on study.
Dose-Escalation and Dose-Expansion Phase: Duration of Response (DoR)RECIST assessments performed at screening (within 28 days before start of study treatment), Day 1 of Cycle 2, and every 8 (+/-1 week) weeks afterwards until the occurrence of disease progression, up to a maximum of 90 monthsThe DoR was defined as the time from the first time that the objective response reached CR or PR, whichever came first (and later confirmed), until the occurrence of PD or death. The CR was defined as disappearance of all target lesions. The PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. The PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (nadir), including baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters. The appearance of 1 or more new lesions was also considered progression.
Dose-Escalation and Dose-Expansion Phase: Maximum Observed Plasma Concentration (Cmax) of SurufatinibPre-dose and 1, 2, 4, 6, 8 hours post-dose on Days 1 and 15 of Cycle 1Plasma samples were collected to determine Cmax of surufatinib.
