Evaluation of CureXcell® in Treating Chronic Venous Leg Ulcers

September 22, 2015 updated by: Macrocure Ltd.

A Phase-3 Prospective, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability and Efficacy of CureXcell® as an Adjunct to Good Ulcer Care Measures in Treating Chronic Venous Leg Ulcers

The primary objective is to evaluate the clinical benefit of CureXcell® as adjunct to Standard of Care in the treatment of Chronic Venous Leg Ulcers. CureXcell® is a cell based therapy, containing activated homologous white blood cells prepared from donated healthy whole blood. A total of 252 patients will be randomized to receive either CureXcell® 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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Ankle Brachial Pressure Index (ABI) ≥ 0.80
  • Venous insufficiency confirmed by duplex Doppler ultrasound
  • Presence of a venous leg ulcer, unresponsive to Standard of Care treatment for at least 4 weeks and between ≥ 1 cm2 and ≤ 17.1 cm2 at screening; and between ≥ 1 cm2 and ≤ 12cm2 at the Baseline Visit

Exclusion Criteria:

  • Target Ulcer has decreased >30% in size from Screening to Baseline
  • Documented history of osteomyelitis at the Target Ulcer location within 6 months preceding the Baseline Visit.
  • Patients who are unable to tolerate multi-layer compression therapy.
  • Ulcer, which in the opinion of the Investigator is suspicious for cancer.
  • Any malignancy within the past 5 years, excluding successfully treated basal cell carcinoma or squamous cell carcinoma without evidence of metastases.
  • History of radiation at the Target Ulcer site in previous 12 months prior to Baseline Visit.
  • Patients with clinically significant claudication
  • Current sepsis
  • Patients with known history of significantly compromised immunity for any reason including radiation therapy, chemotherapy or HIV

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: CureXcell®
CureXcell® injection will be administered about every 4 weeks for up to 3 treatments, or until ulcer closure, whichever occurs first.
Biological: CureXcell®
CureXcell® is a cell based therapy obtained from donated whole blood. The blood is collected from healthy young adults, the white blood cells are separated and then activated by hypo-osmotic shock.
Placebo Comparator: Placebo injection
The placebo will be administered by injecting normal saline at each centimeter of the ulcer bed.
Other: Placebo injection
Normal saline injected at each centimeter of ulcer bed

What is the study measuring?

Time Frame: up to 16 weeks
Time to complete closure of Target Ulcer at any time during the 12-week Treatment Phase. Complete closure is confirmed at two consecutive study visits two weeks apart.
up to 16 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.
