About this trial

Chemotherapy induced peripheral neuropathy (CIPN) is one of the most limiting side effects of chemotherapy and often leads to adaptations in the protocol of the chemotherapy including dose reduction or even discontinuation of treatment. In general, the symptoms of CIPN are sensory, often distributed in a "stocking and glove" manner, and include pain, tingling, and numbness. CIPN has a marked negative influence on quality of life of patients and their families. It may result in serious limitations in daily functioning and affect the enjoyment, social relationships, and ability to perform work. Current management of CIPN (i.e. prevention and treatment) includes dose reduction or delay of chemotherapy cycles and treatment discontinuation. Unfortunately, this reduces the chance of an effective cancer treatment. Current guidelines of the American Society of Clinical Oncology (ASCO) on the Prevention and Management of Chemotherapy-Induced Peripheral Neuropathy do not conclusively recommend any agent for the prevention of CIPN. Due to the scarcity of drugs that are effective for preventing and treating CIPN, the distress of patients who suffer from CIPN, and the major societal and economic costs, new approaches and effective treatment strategies are required.

The proposed trial is a parallel, double blind, placebo controlled, randomised trial, aiming to determine whether treatment with SMP reduces the severity of symptoms of paclitaxel-induced peripheral neuropathy, as compared to placebo.

Treatments tested in this trial

  • Stibium metallicum praeparatum 6x

    Drug

    Stibium metallicum praeparatum D6 will be administered with subcutaneous injections 3 times a week at 1 ampoule at 1 mL during the chemotherapy and shall be continued during 6 weeks after the end of chemotherapy . The first injection will be administered on the day of the first dose of chemotherapy, before the injection of the first dose of chemotherapy.

  • Placebo

    Drug

    Placebo will be administered with subcutaneous injections 3 times a week at 1 ampoule at 1 mL during the chemotherapy and shall be continued during 6 weeks after the end of chemotherapy . The first injection will be administered on the day of the first dose of chemotherapy, before the injection of the first dose of chemotherapy.

Trial outcomes

Primary outcomes

1

Time frame
Weekly from week 1 (Baseline) - 13

Secondary outcomes

1
