View original scientific description
Patients with refractory metastatic colorectal cancer or non-small cell lung cancer with liver metastasis treated with Trans-arterial Tirapazamine Embolization along with Pembrolizumab.
Interventions
DRUG
TATE and pembrolizumab
All liver metastatic lesions will be treated with TATE for maximally debulking. Pembrolizumab IV infusion per standard schedule every 3 or 6 weeks until progression or maximally 2 years.
DRUG
TAS-102 pill
The comparator of the mCRC arm is TAS-102 at 60 mg BID 5 days per week for 2 weeks then 2 weeks off.
DRUG
Regorafenib Pill
As an alternative to TAS-102 per treating physician's discretion. If selected, Regorafenib 160 mg oral daily for 3 weeks on and one week off, every 4 weeks per cycle. Do not take Regoarefnib if taking TAS-102.
Primary outcome measures
Overall Survival for the mCRC cohort
Time frame: 24 months
From the first day of treatment to death
Overall Response Rate (ORR) for the NSCLC cohort
Time frame: within 24 months
Per RECIST 1.1 criteria

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
