화학요법으로 인한 말초 신경병증에 따른 감각 이상(무감각, 따끔거림)에 대한 오존 치료: RCT. (OzoParQT)
화학요법으로 인한 말초 신경병증에 따른 감각 이상(저림, 저림) 환자에서 오존 치료의 효과 및 비용 효율성. 무작위 삼중맹검 임상시험(OzoParQT).
The goal of this phase II/III randomized clinical trial is to evaluate the effect of adding rectal ozone therapy to the usual management of patients with paresthesia (numbness and/or tingling) due to chemotherapy-induced peripheral neuropathy (CIPN). Ozone treatment consists of the rectal insufflation of 180 - 300 milliliters of an ozone/oxygen gas mixture.
The main questions to answer are:
- Can ozone therapy improve patients' self-perceived level of numbness and tingling?
- Can ozone therapy improve patients' self-perceived health-related quality of life (HRQoL)?
In 42 patients with chronic numbness and tingling secondary to chemotherapy, the researchers will compare:
- the addition of rectal ozone insufflations
- versus the addition of rectal oxygen insufflations (placebo). Participants will receive 40 rectal gas (ozone versus oxygen) insufflations in 16 weeks and will continue other symptomatic or cancer treatments prescribed by their oncologists.
Before treatment, after treatment, and 12 weeks after treatment, they will be evaluated:
- Several questionnaires about neuropathy, quality of life, and anxiety and depression.
- Biochemical parameters of oxidative stress and inflammation
- Hyperspectral images of hands and feet
- Toxicity of procedure.

상세 설명
Rationale Chemotherapy-induced peripheral neuropathy (CIPN) can lead to a decrease and/or interruption of chemotherapy treatment, limiting its efficacy and decreasing patients' quality of life. Therapeutic measures for CIPN are very limited in number and efficacy. Our previous experience has suggested the potential clinical usefulness of adjuvant treatment with ozone in patients with CIPN. The hypothesis of the trial is that ozone treatment will improve numbness and tingling symptoms in patients with CIPN.
Primary objectives:
To evaluate the effect of adding ozone to the usual management of patients with paresthesia (numbness and/or tingling) due to chemotherapy-induced peripheral neuropathy (CIPN), Grade 2 (moderate symptoms and/or limitation in instrumental activities of daily living) or higher, on:
- patients' self-perceived level of paresthesia
- patients' self-perceived health-related quality of life (HRQoL).
Secondary objectives:
To evaluate (in patients with numbness and/or tingling secondary to CIPN) the effect of adding ozone to the usual management on:
- the additional direct costs incurred in the application of ozone and evaluate the cost-effectiveness of the administration of ozone in these patients in comparison with the usual exclusive treatment.
- the evolution of the sensory neuropathy
- the evolution of the level of anxiety and depression,
- the evolution of biochemical parameters related to oxidative stress and chronic inflammation.
- the evolution of hyperspectral signatures obtained from hands and feet.
- to evaluate the toxicity of rectal ozone treatment in these patients.
Main trial endpoints.
- Percentage of change from baseline in "numbness and tingling" self-perceived by patients at the end of follow-up (week 28 after the commencement of ozone treatment)
- Change from baseline in "quality of life" (using the EQ-5D-5L questionnaire) self-perceived by patients at the end of follow-up (week 28 after the commencement of ozone treatment)
Secondary trial endpoints.
To evaluate the percentage of change from baseline in all the secondary objectives:
- at the end of ozone treatment (weeks 16)
- and at the end of follow-up (week 28)
Trial design. Phase II-III randomized triple-blind clinical trial. The duration of each patient in the study will be 28 weeks: 16 weeks of treatment and 12 weeks of follow-up. The planned total duration of the project is 60 months.
Trial population. 42 adult patients (>= 18 years old), with any tumor, with paresthesias (numbness and/or tingling) due to CIPN, grade of toxicity >= 2 (according to the Common Toxicity Criteria for Adverse Events (CTCAE) from the National Cancer Institute of EEUU, v.5.0), for >= 3 months.
Intervention.
All patients will receive the usual management and treatment for their symptoms + "40 sessions of rectal insufflation of O3/O2 gas mixture" in 16 weeks (3 or 2 sessions per week):
- Ozone group, O3/O2 concentration increasing from 10 to 30 µg/mL (µg of O3 by mL of O2).
- Control-placebo group, O3/O2 concentration = 0 µg/mL (this is: only O2).
