Proof of Principle Study Evaluating Gonyautoxins NEURO SERUM, on Chemotherapy-induced Peripheral Neuropathy
Brazil52 participantsStarted 2021-01-14
Plain-language summary
Proof-of-concept study to assess the effects of gonyautoxins (PSP NEURO SERUM) on safety and tactile sensitivity on patients with chemotherapy-induced peripheral neuropathy (CIPN). This is a multicenter, prospective proof-of-concept study in patients with solid tumors affected by CIPN. The study will be divided into two parts: Part 1 will assess the activity and tolerability of PSP NEURO SERUM and part 2 consists of a randomized cohort that will compare the activity of PSP NEURO SERUM vs placebo. Part 2 will depend on the results of part 1. If there are less than 8 responses in part 1, the study will be interrupted, and it will not be recommended to proceed with part 2.

Inclusion criteria
. Written informed consent
. Age ≥18 years
. Histological diagnosis of cancer (hematologic or solid tumors).
. Part 1: Treatment with antineoplastic agents that induce peripheral neuropathy in neoadjuvant, adjuvant, or metastatic scenario; Part 2: Treatment with taxanes peripheral neuropathy inducers in the neoadjuvant, adjuvant, or metastatic scenario.
. Peripheral sensory neuropathy grade 2 or higher on upper limbs as per NCI-CTCAE v5.0. and with alteration of the Semmes Weinstein monofilament test.
. Part 1: Diagnosis of peripheral sensory neuropathy during treatment with antineoplastic agents drugs that induce peripheral neuropathy or up to 2 weeks after the last chemotherapy infusion; Part 2: Diagnosis of peripheral sensory neuropathy during treatment with peripheral neuropathy-inducing taxanes or up to 2 weeks after last chemotherapy infusion.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Evaluate the change in response caused by PSP NEURO SERUM on the tactile sensation from baseline to day 28.
. Patients using neuropathic pain modulators will be allowed if there is no dose adjustments in the last 2 weeks and if sensory symptoms persist related to CIPN, or if the use is for another indication.
. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 to 2.
0. Documented willingness to use an effective contraceptive method while participate in the study for male patients with partners or female participants with the potential to become pregnant.
1. Part 1: Hand skin and cuticles must be intact. Part 2: Skin of hands, feet and cuticles must be intact.
. Prior treatment with gonyautoxins or any small molecule neurotoxins.
. Female participants who are pregnant (positive urine pregnancy test), who have an infant they are breastfeeding, or intend to become pregnant within 3 months.
. History of peripheral sensory neuropathy attributed to any cause other than chemotherapy.
. Patients receiving systemic treatment that has among its common side effects (\> 1%) peripheral neuropathy, or who have received the same within the last 2 weeks. The use during the study of systemic drugs such as hormone therapy (e.g. tamoxifen, aromatase inhibitor, etc), or other agents that do not have among their common side effects (\>1%) peripheral neuropathy, will be allowed.
