Phase 2a Study to Evaluate Suppression of Methotrexate-induced Mucositis by TK112690 (TK112690)

August 11, 2023 updated by: Tosk, Inc.

Phase 2a, Multi-center, Placebo-controlled, Randomized, Partially Blinded, Study Infused TK112690 or or Placebo Administered Along With Methotrexate Weekly for Four Consecutive Weeks to Patients With Recurrent or Residual SCCHN

Patients will receive methotrexate at a dose of 45 mg/m2 administered weekly for 4 consecutive weeks as an iv infusion along with a nutritional supplement administered two hours before the methotrexate. One hour before the methotrexate treatment the patients will be administered the first infusion of the day of either TK112690 or placebo depending on randomization. Five hours after the methotrexate treatment the patients will be administered the second treatment of either TK112690 or placebo depending on randomization. The TK112690 dose will be 45 mg/kg.

Detailed Description

Patients will receive methotrexate at a dose of 45 mg/m2 administered weekly for 4 consecutive weeks as an iv infusion along with a nutritional supplement administered two hours before the methotrexate. One hour before the methotrexate treatment the patients will be administered the first infusion of the day of either TK112690 or placebo depending on randomization infusion. Five hours after the methotrexate treatment the patients will be administered the second treatment of either TK112690 or placebo depending on randomization. The TK112690 dose will be 45 mg/kg.

  • A total of 22 patients will be enrolled into one of 2 different dose groups: TK-112690 treated or placebo treated.
  • Screening must be within 15 days of subject enrollment.
  • Patients will remain for observation at the clinical site for a minimum of 25 hours post initial TK112690 or placebo dose.
  • Study follow-up will occur on Week 6, two weeks after the last dosing of methotrexate.
  • Blinding: The study will be partially blinded. The patient and investigator will be blinded as to whether TK112690 or placebo is administered. The CRO, sponsor, and site pharmacist will know whether the patient was administered active drug or placebo.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria

  • Male and female subjects over 18 years old with a histologically or cytological confirmed diagnosis of locally residual, recurrent or metastatic SCCHN.

Parameter Laboratory Values Serum creatinine ≤1.5 x ULN Est. creatinine clearance ≥45 mL/min Total bilirubin ≤2.0 mg/dL (≤34.2 μmol/L) AST & ALT ≤3 x ULN Absolute granulocytes ≥1.5 x 109 cells/L Platelets ≥100,000/µL

● Be able to read and understand, and provide a signature or thumb impression on the Informed Consent Form (ICF) before entering the study.

  • Current mucositis (>Grade 1).
  • Pregnant or nursing mother.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mucositis
Time Frame: up to 4 Weeks

Mucositis Evaluation Using Established Scoring Systems: NCI/CTCAE at 4 WKs (Primary) and WHO at 4 WKs (Primary).

NCI/CTCAE=National Cancer Institute/Common Terminology Criteria for Adverse Events and WHO=World Health Organization

NCI Grades- 0= No mucositis, 1=Mild mucositis (Painless ulcers, erythema, or mild soreness in the absence of lesions), 2=Moderate mucositis (Painful erythema, edema, or ulcers but eating or swallowing possible), 3= Severe mucositis (Painful erythema, edema, or ulcers requiring IV hydration), 4=Life threatening, 5=Death WHO Grades- 0=No mucositis, 1= Mild (Oral soreness, erythema), 2=Moderate (Oral erythema, ulcers, solid diet tolerated), 3=Severe (Oral ulcers, liquid diet only), 4=Life-threatening (Oral alimentation impossible).

For both the scales above, a higher score implies greater mucositis.

Scale specific mean values for patients in each group (placebo or treated) are calculated and compared by Student's t-test.
up to 4 Weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
