Evaluation of the Safety and Efficacy of Esperanza Extract (PA001)

• Status: Not yet recruiting
• Trial end date: 2023-06-15
• Target enrollment: 0
• Participant gender: All

Summary

This is a phase Ib/II clinical study that has two phases. In phase Ib, the safety evaluation of the extract of Petiveria alliacea (Esperanza) will be carried out in patients with metastatic gastrointestinal tumors (colon, pancreas, stomach, and biliary tract) and patients with newly diagnosed and relapsed acute leukemia. In phase IIb, the safety will continue to be evaluated, and the efficacy of the Esperanza extract will be explored in combination with chemotherapy in patients with metastatic gastrointestinal tumors (colon, pancreas, stomach, and biliary tract) with newly diagnosed acute leukemias and relapses.

• Phase: Phase 1/Phase 2

Criteria

Inclusion Criteria Solid Tumors:

1. Patients must be over 18 years of age, with no upper age limit

2. Histological diagnosis of gastrointestinal cancer may include stomach, colon, bile ducts, and pancreas.

3. Measurable disease through diagnostic tests and who will receive chemotherapy as primary treatment for their disease.

4. At least one discrete metastatic site identified

5. ECOG scale status from 0 to 2 with survival more significant than two months.

6. Subject can swallow and retain oral medication and does not have uncontrolled emesis or persistent diarrhea.

7. Adequate renal, hematological, hepatic, and cardiac function at the investigator's discretion.

8. Without uncontrolled or significant comorbidities determined by clinical history, physical examination, and screening laboratories at the investigator's discretion.

9. Patients of childbearing age and without safe non-hormonal planning methods must have a negative pregnancy test before the screening.

10. Fertile female subjects (those who have not been postmenopausal for at least 12 months or are surgically sterile by bilateral tubal ligation, bilateral oophorectomy, or hysterectomy) and their male partners must use at least one of the contraceptive methods listed below during study entry, throughout the study, and for at least six months after use of the P2Et extract (the effects of the P2Et extract on the developing human fetus are unknown):

a. Complete abstinence from sexual intercourse, beginning at least one complete menstrual cycle before administration of study drug; (It should be noted: sexual abstinence as a contraceptive method should be limited to those cases where it is already established as the patient's pre-existing lifestyle choice).

b. Vasectomy in the partner of a female subject c. Intrauterine device (IUD) d. Double-barrier method (condom, contraceptive sponge, diaphragm, or vaginal ring with spermicidal jelly or cream).

k) Desire to complete the study and follow-up interventions.

Inclusion Criteria Acute Leukemia:

1. Patients must be over 18 years of age, with no upper age limit

2. Patients who have had a new diagnosis of acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) will be eligible for the study and are eligible for chemotherapy treatment.

• Patients must be newly diagnosed

• Patients must have failed initial therapy, which may manifest in any of the following ways:

• Demonstration of primary refractory disease (primary induction failure) as evidenced by mid-cycle bone marrow analysis showing lack of complete tumor clearance (CTC).

• Relapse of the initial disease after a period of achieving complete remission.

3. Subject can swallow and retain oral medication and does not have uncontrolled emesis or persistent diarrhea.

4. Adequate renal, hematological, and hepatic function at the investigator's discretion.

5. Without uncontrolled or significant comorbidities determined by clinical history, physical examination, and screening laboratories at the investigator's discretion.

6. Patients of childbearing age and without safe non-hormonal planning, methods must have a negative pregnancy test before the screening.

7. Fertile female subjects (those who have not been postmenopausal for at least 12 months or are surgically sterile by bilateral tubal ligation, bilateral oophorectomy, or hysterectomy) and their male partners must use at least one of the contraceptive methods listed below. Listed below during study entry, throughout the study, and for at least six months after use of the P2Et extract (the effects of the P2Et extract on the developing human fetus are unknown):

a. Complete abstinence from sexual intercourse, beginning at least one complete menstrual cycle before administration of study drug; (It should be noted: sexual abstinence as a contraceptive method should be limited to those cases where it is already established as the patient's pre-existing lifestyle choice).

h) Desire to complete the study and follow-up interventions.

Exclusion Criteria:

The exclusion criteria apply to solid tumors as well as hematological tumors.

Subjects with one or more conditions are not eligible for this study.

1. Subjects treated in any other therapeutic clinical protocol 30 days prior to study entry or during study participation.

2. Patients receiving other investigational agents.

3. The female subject is pregnant or nursing. A negative serum or urine pregnancy test obtained at screening should confirm that the woman is not pregnant. Pregnancy tests are not required for postmenopausal or surgically sterilized women.

4. Serious concomitant morbidity, active at the discretion of the investigator

5. Subjects with a confirmed diagnosis of HIV before enrollment or a positive diagnosis of HIV at the time of screening.

6. Recipients of solid organ transplants.

7. Any condition that, in the opinion of the principal investigator, makes the subject ineligible to participate in this study.
