Esophageal Cancer Clinical Trial
Antitumor-B KAC PK Study
Study Design: A Window of Opportunity Clinical Trial. This study design permits examination of effects of an oral agent on cancer patients during the "window" between diagnosis of their cancer and their definitive cancer surgery. Similar to a phase 0 study, the trial design permits examination of the biologic effects of an agent; in this study pharmacokinetic properties will be examined.
Study Rationale: Establishing the PK profile for antitumor B key active components (ATB-KAC) is a critical initial step before future clinical trials can be performed that examine anticancer and cancer preventive effects of ATB-KAC.
Study Intervention Description: Study participants will take the natural botanical compound ATB-KAC during a short window (seven to 28 days). Participants will provide blood samples and saliva samples during ATB-KAC administration and a portion of the initial tumor biopsy.
Clinical diagnosis of oral cavity squamous cell cancer.
Patient can start study agent administration but histological confirmation of squamous cell cancer (SCC) of the oral cavity (or histologic variants of SCC) by the pathologist must happen within seven days of registration in order to continue study agent administration.
Clinical stage II-IVA (as defined by the AJCC, 8th Edition) and amenable to surgical resection.
New diagnosis of oral SCC, new second primary, or recurrent oral SCC following a minimum remission of six months following previous definite surgery.
History and physical examination by an otolaryngologist and medical oncologist within 30 calendar days of study registration.
Study agent administration should start within seven days of registration.
Patient must receive administration of study agent for a minimum of seven days.
ECOG Performance status < 2.
Age ≥ 18 years.
CBC/differential obtained within 30 calendar days prior to registration, with adequate bone marrow function defined as follows:
Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3; Platelets ≥ 100,000 cells/mm3; Hemoglobin ≥ 8.0 g/dL (Note: The use of transfusion or other intervention to achieve Hgb ≥ 8.0 g/dL is acceptable.);
Adequate renal and hepatic function within 30 calendar days prior to registration, defined as follows:
Serum creatinine < 1.5 mg/dL or creatinine clearance (CrCl) ≥ 50 mL/min within 14 calendar days prior to registration, determined by 24-hour collection or estimated by Cockcroft-Gault formula:
CrCl male = [(140 - age) x (weight in kg)], [(Serum Cr mg/dL) x (72)] CrCl female = 0.85 x (CrCl male)
Total bilirubin < 2 x the institutional ULN within 30 calendar days prior to registration.
AST or ALT ≤ 3 x the institutional ULN within 30 calendar days prior to registration.
Glucose, potassium, and sodium within 30 calendar days prior to registration, with the following required parameters:
Glucose: > 40 mg/dL or < 250 mg/dL; Potassium: > 3 mmol/L or < 6 mmol/L; Sodium: > 130 mmol/L or < 155 mmol/L.
Female patients must meet one of the following:
Postmenopausal for at least one year before the screening visit, or
Surgically sterile (i.e., undergone a hysterectomy or bilateral oophorectomy), or
If subject is of childbearing potential (defined as not satisfying either of the above two criteria), agree to practice two acceptable methods of contraception (combination methods requires use of two of the following: diaphragm with spermicide, cervical cap with spermicide, contraceptive sponge, male or female condom, hormonal contraceptive) from the time of signing of the informed consent form through 90 days after the last dose of study agent, AND o Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptom-thermal, post ovulation methods] and withdrawal are not acceptable contraception methods.)
Male patients, even if surgically sterilized (i.e., status postvasectomy), must agree to one of the following:
Practice effective barrier contraception during the entire study period and through 60 calendar days after the last dose of study agent, OR
Must also adhere to the guidelines of any study-specific pregnancy prevention program, if applicable, OR
Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptom-thermal, post ovulation methods] and withdrawal are not acceptable methods of contraception.)
Patients must be deemed able to comply with the study plan.
Gastric tube study agent administration is permissible.
Patients must provide study-specific informed consent prior to study entry.
History of active liver disease.
Pregnant or lactating women are ineligible due to unforeseeable risks to embryo or fetus.
Concurrent use of any medicinal botanical, natural, or other herbal compound/s that the study PI believes could potentially have an impact on the results/objectives of this study.
Planned subtotal or debulking surgery, as determined by enrolling physician determination, is not permissible.
Prior systemic chemotherapy for oral SCC; note that prior chemotherapy for a different cancer is allowable.
Prior radiotherapy for oral SCC is permissible if disease free for one year since prior oral cancer treatment and free of significant late radiation effects.
Severe active comorbidity, such as uncontrolled cardiac disease, infection, severe COPD.
