Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

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.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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 to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

1. Signed written informed consent 2. Male and Female ages 18 to 70 years old. To be able to eliminate Type I Diabetes Mellitus among the younger subjects, we will only recruit patients who are stable on oral hypoglycemic agent. 3. Established diagnosis of diabetes mellitus type 2 (National Diabetes Data Group) who are currently on good control of the diabetic state.

4. Presence of predominantly distal symmetrical sensory polyneuropathy of the lower limbs as assessed by NSS, NIS and NCS.

Exclusion Criteria:

  1. Current use of potentially neuropathic agents (Isoniazid, Phenytoin, Dapsone, Metronidazole, Vinca Alkaloids, etc.) within the past 1 month;
  2. Presence of severe metabolic disease (renal failure, hepatic failure, etc.), alcoholism and malignancy;
  3. Presence of hemorrhagic tendencies;
  4. Patients who are diagnosed to be of Type 1 Diabetes Mellitus;
  5. Pregnant and lactating patients, including those who plan to have pregnancy within the study period.
  6. Concomitant intake of agents currently used to treat neuropathic pain like gabapentin, carbamazepine/ oxcarbazepine, anti-depressants (tricyclic anti-depressants and SSRIs) and topical capsaicin.
  7. Concomitant intake of other anti-platelet agents, rheologic agents and anticoagulants.
  8. Have received Cilostazol therapy within the past three (3) months

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.
Outcome Measure
Time Frame
Subjective neuropathy assessment by NSS (Neuropathy Symptom Scores)from Baseline (BS) to week 12 (W12) after Cilostazol therapy of the three (3) arms of the study.
Time Frame: 12 weeks
12 weeks
Objective neuropathy assessment by NIS (Neuropathy Impairment Scores)from Baseline (BS) to week 12 (W12) after Cilostazol therapy of the three (3) arms of the study.
Time Frame: 12 weeks
12 weeks
Electrophysiologic assessment by NCS (Nerve Conduction Studies) from Baseline (BS) to week 12 (W12) after Cilostazol therapy of the three (3) arms of the study.
Time Frame: 12 weeks
12 weeks
To determine the relationship of peripheral neuropathy with peripheral vascular disease using the WIQ and the ABI from baseline to W12.
Time Frame: 12 weeks
12 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.
Outcome Measure
Time Frame
To determine if there is improvement in subjective parameters of neuropathy as assessed by NSS and NSC (Neuropathy Symptoms and Change Questionnaire) from baseline to week 4 (W4), week 8 (W8) and week 12 (W12) after Cilostazol therapy.
Time Frame: 12 weeks
12 weeks
To determine if there is improvement in objective parameters using NIS and NCS from baseline to W4, W8 and W12 after Cilostazol therapy.
Time Frame: 12 weeks
12 weeks
To compare the effectivity of low dose (100mg) and high dose (200mg) Cilostazol based on subjective (NSS, NSC) and objective parameters (NIS, NCS) from baseline, to W4, W8 and W12.
Time Frame: 12 weeks
12 weeks
To assess the safety of Cilostazol therapy.
