Study of PG2 Injection for Improving Fatigue in Patients After Palliative Abdominal Surgery for Cancer

June 2, 2025 updated by: PhytoHealth Corporation

The Phase II Clinical Study of PG2 Injection for Improving Fatigue in Patients After Palliative Abdominal Surgery for Cancer

PG2 has been approved in Taiwan to treat cancer-related fatigue for advanced cancer patients. The primary objective of this study is to evaluate the efficacy of PG2 on fatigue relief in patients undergoing palliative abdominal surgery for cancer. The secondary endpoints, including the length of hospital stay, postoperative complications, HRQL, inflammatory biomarkers, the duration of antibiotic therapy, mortality during the hospital stay, weight loss and body composition, will be evaluated among these patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This will be a double-blind, randomized, and placebo-controlled study. At least 40 evaluable patients who are scheduled for palliative abdominal surgery for cancer will be randomly assigned to the control or treatment group. Each group will have at least 20 patients and be treated as follows: 1) control group: patients will accept placebo 1 dose a day (POD-1) before surgery and 1 dose a day for 3 days after surgery (POD+0 to POD+2); 2) treatment group: patients will accept PG2 1 dose a day (POD-1) before surgery and 1 dose a day for 3 days after surgery (POD+0 to POD+2).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients who have cancer and are scheduled for palliative abdominal surgery for cancer
  • Age > 20 years older
  • Patients who signed the informed consent form

Exclusion Criteria:

  • Patients, at screening, has levels greater than 2.5 times the upper limit of normal liver function of alanine aminotransferase or aspartate aminotransferase.
  • Patients has a severe renal impairment (defined as serum creatinine greater than 2 times the upper limit of normal or BUN greater than 2.5 times the upper limit of normal for range); or the subject is on dialysis.
  • Patients have ongoing infection, respiratory tract dysfunction, cardiac dysfunction or immune disorder that, in the opinion of the investigator, may interfere with conduct of the study.
  • Patients who are not suitable for undergoing surgery (e.g. congenital hemostatic disorders) by the investigator's judgment.
  • Patients have enrolled or have not yet completed other investigational drug trials within 1 month before screening.
  • Female patients are pregnant or breast-feeding.
  • Patients who require preoperative nutritional support
  • Patients with serious comorbidities (American Society of Anesthesiologists Risk Class of 4 or 5).
  • Patients who is unwilling or unable to answer the quality of life questionnaires i.e. the BFI-T and EORTC QLQ-C30.
