A Single Arm, Open-label,Phase Ib Study of CT053PTSA in Preciously Treated Patients With Advanced and Metastatic RCC

Phase 1
Terminated
Conditions
Renal Cell Cancer Metastatic
Interventions
Registration Number
NCT03876925
Lead Sponsor
Sunshine Lake Pharma Co., Ltd.
Brief Summary

This is a phase Ib,single arm,open label study evaluating the safety and efficacy of CT053PTSA in patients with advanced and metastatic renal cell cancer who have progressed from previous treatment

Detailed Description

This study is being carried out in two parts,part 1 and part 2. Part 1: This is the dose-escalation part. The primary purpose of the part 1 portion is to determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD), and recommend the appropriate doses of CT053PTSA for further study Part 2: This is the expansion part.The part 2 portion of this study will continue to evaluate the safety and efficacy of CT053PTSA at the appropriate dose recommended in Part 1,in patients with advanced and metastatic RCC

Inclusion Criteria
  • Histologically or cytologically confirmed renal cell cancer.Patients must be diagnosed with advanced or metastatic disease,disease progressed to previous treatment .
  • Measurable disease according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1)
  • Toxicity recovered to NCI CTCAE v.4.03 Grade ≤1 from previous treatments (except alopecia)
  • ECOG performance status (PS) 0 or 1
  • Life expectancy of ≥ 12 weeks
  • Adequate organ function
  • Voluntary agreement to provide written informed consent and the willingness and ability to comply with all aspects of the protocol
Exclusion Criteria
  • Chemotherapy,radiotherapy,immunotherapy and targeted therapy less than 4 months prior to administration.
  • Symptomatic, untreated or unstable central nervous system metastases
  • Uncontrolled hypertension that require anti-hypertensive agents to control, or systolic blood pressure (BP) >140mmHg or diastolic BP >90 mmHg before the first administration (BP is the mean blood pressure of two measures that 1 hours interval or above)
  • Doppler ultrasound evaluation:Left ventricular ejection fraction < 50%
  • Significantly clinical arrhythmia or symptomatic bradycardia, or male with QTCF > 450 ms or female with QTCF > 470 ms, or patients with a history of torsion or congenital QT prolonged syndrome long QT syndrome
  • Certain factors that would preclude adequate absorption of CT053PTSA and gefitinib (eg. unable to swallow, chronic diarrhea, intestinal obstruction)
  • Patients with evidence of bleeding tendency, including the following cases: gastrointestinal bleeding, hemorrhagic gastric ulcer, fecal occult blood ++ and above; or melena or hematemesis within 2 months; or visceral bleeding that may occur considered by investigator
  • History of organ transplantation
  • Any disease of the following bellowed within 12 months prior to administration: Myocardial infarction, severe angina, or unstable angina, coronary or peripheral artery bypass graft, congestive heart failure
  • Pulmonary embolism or cerebrovascular events (including transient ischemic attack)within 6 months prior to administration
  • Infection of HIV
  • Patients with infection of HBV or HCV. Patients with positive of HBsAg or HBcAb,and HBV-DNA can be measured (>500IU/ml). Patients with positive of anti-HCV,and HCV-RNA can be measured by PCR.
  • Other malignancies within 5 years prior to enrollment, with the exception of carcinoma in situ of the cervix, basal or squamous cell skin cancer
  • Pregnant or lactating woman
  • Any other reason the investigator considers the patient is not suitable to participate in the study

Primary Outcome Measures
NameTimeMethod
Part 1(dose-escalation part):Maximum Tolerated Dose (MTD)Cycle 1 Day 1 to Cycle 1 Day 28

The maximum tolerated dose (MTD) of the CT053PTSA will be determined according to incidence of dose-limiting toxicity (DLT) assessed by NCI CTCAEv4.03

Part 2 (expansion part):Overall Response Rateup to approximately 24 months

Overall response rate (ORR),defined as a partial response (PR) or complete response (CR) occurring at any point post-treatment according to Response Evaluation Criteria in Solid Tumors as assessed by RECIST1.1

Secondary Outcome Measures
NameTimeMethod
Number of patients with adverse events (AEs) as a measure of safety and tolerabilityup to approximately 24 months

Safety and tolerability will be assessed through AEs, via monitoring changes in physical examination, clinical laboratory parameters, vital signs and ECGs

Disease Control Rate (DCR)up to approximately 24 months

DCR, proportion of patients with best overall response of CR, PR or SD

Progression-free Survival (PFS)up to approximately 24 months

PFS, defined as time from date of treatment to disease progression or death due to any cause

Duration of Response (DOR)up to approximately 24 months

DOR, defined as time from the first documented CR or PR to first documented progression or death due to any cause

Overall Survival (OS)up to approximately 24 months

OS, defined as time from date of treatment to death due to any cause

Maximum observed plasma concentration (Cmax)Cycle 1 Day1 and Day 28

to assess the pharmacokinetic profile

Time of maximum observed plasma concentration (Tmax)Cycle 1 Day1 and Day 28

to assess the pharmacokinetic profile

Area under the plasma concentration time curve (AUC)Cycle 1 Day1 and Day 28

to assess the pharmacokinetic profile
