About this study

Official title: A Phase I, Open-label, Dose-finding Study to Assess the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of TRX-920 Oral Gel (10 mg and 30 mg) in Patients With Advanced Solid Tumors

The study drug TRX-920 Oral Gel contains SN38, an active metabolite of Irinotecan (CPT-11), which is a widely prescribed anti-cancer drug that has been approved in many countries for the treatment of colorectal and pancreatic cancer. TRX-920 is the oral gel formulation that directly contains SN38 instead of Irinotecan. A series of biology and animal studies have demonstrated that the TRX-920 Oral Gel could inhibit tumor growth with fewer side effects compared to Irinotecan.

Read the detailed description

This is the first study in which the study drug TRX-920 Oral Gel is being given to humans. However, as a metabolite of Irinotecan, SN38 has proved its effectiveness in the treatment of colorectal and pancreatic cancer. TRX-920 also showed its effect of anti-tumor in various cancer cell lines and animal models. The purposes of this study are to find the highest dose of the study drug that can be given without causing significant side effects, the side effect of the study drug, the concentration of the study drug in the blood, and the effect on your specific cancer.

The clinical study will be conducted in Taiwan. The drug used in this study is an investigational product (TRX-920 Oral Gel) which is provided free of charge by TaiRx, Inc. (a pharmaceutical company in Taiwan, and is the sponsor of this study), and is a potential oral anti-cancer therapy for patients suffering from various cancers.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TRX-920 Oral Gel (10 mg and 30 mg)Drug

    TRX-920 Oral Gel will be administered orally at a week (BIW) in an 8-week cycle. No food should be taken 2 hours before and 1 hour after taking TRX-920. The dose escalation/de-escalation rules will be based on definitions of dose-limiting toxicity (DLT) and will be monitored during the first treatment cycle (i.e., the first 4 weeks post the first dose).

    The starting dose will be 1 mg and the dosing frequency is twice every week (BIW). Subjects will be assigned to a dose level in sequential cohorts based on the order of their enrollment. The dose escalation will follow a 3+3 design and doses escalate from approximately 1 mg BIW, 2 mg BIW, 4 mg BIW, 8 mg BIW, and 16mg BIW and the doses for subsequent cohorts will be determined by Safety Review Committee (SRC). Dose escalation will be stopped till the maximum tolerated dose (MTD) is reached or identified.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) of TRX-920 Oral Gel

    The MTD is defined as the highest dose level at which no more than 1 in 6 subjects experiences a DLT. The recommended Phase 2 dose (RP2D) will be determined by Safety Review Committee based on all available PK, safety, and preliminary efficacy data. The RP2D will not exceed the MTD.

    Measured: the first 4 weeks post the first dose

  2. Frequency, type, severity and relationship to study drug of adverse events (AEs) of TRX-920 Oral Gel

    AEs will be coded by system organ class (SOC) and preferred term according to the Medical Dictionary for Regulatory Activities (MedDRA) system.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days)

Secondary outcomes (9)
  1. Drug exposure and human pharmacokinetics (Cmax) of SN38 derived from plasma concentration-time profiles

    The plasma concentrations of SN38 will be analyzed using compartmental or non-compartmental approach to calculate Cmax for individual subjects.

  3. Drug exposure and human pharmacokinetics (MRT) of SN38 derived from plasma concentration-time profiles

    The plasma concentrations of SN38 will be analyzed using compartmental or non-compartmental approach to calculate MRT for individual subjects.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days)

  4. Drug exposure and human pharmacokinetics (AUC) of SN38 derived from plasma concentration-time profiles

    The plasma concentrations of SN38 will be analyzed using compartmental or non-compartmental approach to calculate AUC for individual subjects.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days)

  5. Drug exposure and human pharmacokinetics (terminal half-life) of SN38 derived from plasma concentration-time profiles

    The plasma concentrations of SN38 will be analyzed using compartmental or non-compartmental approach to calculate terminal half-life (T 1/2) for individual subjects.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days)

  6. Objective response rate (ORR) per RECIST v1.1

    Tumor assessment by computed tomography (CT) or magnetic resonance imaging (MRI) will be performed every 8-week cycle starting from Cycle 2 Day 1. All subjects will attend an End of Treatment (EOT) visit at the time decision is made to discontinue study drug administration.

    The Objective response rate (ORR) as per RECIST v1.1 will be calculated in the efficacy population.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days)

  7. Disease control rate (DCR) per RECIST v1.1

    Tumor assessment by computed tomography (CT) or magnetic resonance imaging (MRI) will be performed every 8-week cycle starting from Cycle 2 Day 1. All subjects will attend an End of Treatment (EOT) visit at the time decision is made to discontinue study drug administration.

    The disease control rate (DCR) as per RECIST v1.1 will be calculated in the efficacy population.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days)

  8. Duration of response (DOR) per RECIST v1.1

    Tumor assessment by computed tomography (CT) or magnetic resonance imaging (MRI) will be performed every 8-week cycle starting from Cycle 2 Day 1. All subjects will attend an End of Treatment (EOT) visit at the time decision is made to discontinue study drug administration.

    The duration or response (DOR) as per RECIST v1.1 will be calculated in the efficacy population.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days), assessed up to 24 months

  9. Time to tumor progression (TTP) per RECIST v1.1

    Tumor assessment by computed tomography (CT) or magnetic resonance imaging (MRI) will be performed every 8-week cycle starting from Cycle 2 Day 1. All subjects will attend an End of Treatment (EOT) visit at the time decision is made to discontinue study drug administration.

    The time to tumor progression (TTP) as per RECIST v1.1 will be calculated in the efficacy population.

    Measured: Cycle 1 Day 1 to study completion, an average of 1 year (each cycle is 56 days), assessed up to 24 months
