An Accessible Low-cost Plant Treatment for Cutaneous Ulcers

September 1, 2020 updated by: Oriol Mitja

In a search for accessible treatment options, plant medicines used by different communities in Papua New Guinea have been tested to identify the sap of the tree, Ficus septica, as a promising antibacterial agent in vitro.

This is an open label clinical trial using an interventional approach, to compare the effect of the antiseptic plant sap and standard topical antiseptic, on the rate of wound development prevention and bacterial growth. If shown to be effective, this readily available plant medicine can provide a zero-cost treatment option in remote areas of PNG.

Detailed Description

The cutaneous ulcer is a painful and debilitating bacterial infection that is common in rural areas of Papua New Guinea (PNG). Systematic treatment with topical antiseptics such as chlorhexidine cream in theory represents a viable treatment option, but in reality, effective treatment of cutaneous ulcers in Papua New Guinea is greatly hindered by the remote and highly inaccessible areas that affected communities often live in. In a search for more accessible treatment options, plant medicines used by different communities in Papua New Guinea have been tested to identified the sap of the tree, Ficus septica, as a promising antibacterial agent in vitro. The sap displays comparable activity to chlorhexidine in disc diffusion assays with gram-positive bacterial wound pathogens. It also appears to dampen the pro-inflammatory responses of neutrophils by down regulating interleukin-6 expression. The sap forms a flexible plastic-like wound covering which may help deter flies from feeding on the wounds, and unlike chlorhexidine cream, the Ficus tree is easy to find where affected communities live. For this reason, this study aims to perform an open label clinical trial using an interventional approach, to compare the effect of this antiseptic plant sap and of a standard topical antiseptic, on the rate of wound development prevention and bacterial growth. If shown to be effective, this readily available plant medicine can provide a zero-cost treatment option in remote areas of PNG.

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

1 year to 11 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

-children aged 5 to 15 with parental consent and with one or more skin breaks of any nature (i.e. Skin cuts, scratch, scrapes or abrasion and mosquito bites) that are less than 1cm in major diameter. Written informed consent by parent or guardian will be required before enrolment.

Exclusion Criteria::

  • All participants who have received medical treatment for skin ulcers up to 2 months prior to recruitment (azithromycin, amoxicillin, benzathine penicillin, etc.).
  • Patients who require antibiotic treatment for another condition not-related to the study.
  • Known history of hypersensitivity, allergic or adverse reaction to the study product.
  • Patients presenting cutaneous ulcer more than 1cm

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.

Time Frame
Number of participants with Clinical Healing in each arm

surface reduction by more than 50%

Number of participants with Clinical Healing in each arm
Time Frame: 21 days
Ulcer healing determined by a professional dermatologist, described as as: appearance of granulation tissue, healed borders, dry ulcer, no exudation.
21 days

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.
