  • Even if the female partner is pregnant, male participants should still use a condom plus spermicide, as indicated above.
  • Female partners (of childbearing potential) of male participants must also use a highly effective method of contraception during the entire period of risk associated with study interventions as described above.
  • FCBP
  • Must use a highly effective method of contraception and avoid breastfeeding during the entire period of risk associated with study interventions which includes the total duration of the study and the drug washout period (9 months after the last dose of study intervention) and have been stable on their chosen method of birth control for a minimum of 3 months before entering the study.
  • Non-sterilized male partners must also use a male condom plus spermicide during the entire period of risk associated with study interventions as described above.
  • A highly effective method of contraception is defined as one that results in a low failure rate (less than 1% per year) when used consistently and correctly. Note that some contraception methods are not considered highly effective.
  • The participants chosen method(s) must be confirmed as highly effective prior to study entry.
  • Participant is capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

Who cannot join

  • Participants must not meet any of the following criteria:
  • Have received chemotherapy known to cause CIPN in the last 12 months.

About this study

Official title: A Pilot Proof of Concept Pharmacokinetic/Pharmacodynamic Study of BXQ-350 in Cancer Patients Exposed to Oxaliplatin and/or Taxane-Based Chemotherapy

This study will assess pharmacokinetic (PK)/pharmacodynamic (PD) relationships and whether BXQ-350 may decrease the intensity and/or duration of chemotherapy induced peripheral neuropathy (CIPN) thereby improving quality of life (QoL) in cancer patients who have been exposed to oxaliplatin and/or taxane-based chemotherapy. This study includes two randomized, placebo controlled, blinded treatment cycles of BXQ-350/placebo, an optional open-label BXQ-350 treatment period, and an unblinded Post-Treatment Follow-up period.

Read the detailed description

BXQ-350 is a novel anti-neoplastic therapeutic agent configured from two components: Saposin C (SapC), an expressed (human) lysosomal protein, and the phospholipid dioleoylphosphatidyl-serine (DOPS), a cell membrane phospholipid (clinical formulation BXQ-350).Due to the presumed mechanism of action of BXQ-350, Bexion anticipates that it may have an impact on ceramides, sphingosine-1-phosphate (S1P), and inflammatory cytokine levels. In addition, pre-clinical results demonstrated that BXQ-350 induced neurite generation and protection in vitro in the PC-12 and NS20Y cell lines and significantly decreased oxaliplatin-induced cold allodynia in a model of CIPN. Thus BXQ-350 may represent a new approach to deliver a neuropathy benefit.

The unique combination of SapC-DOPS along with its proven safety profile and possible neuropathy benefit makes BXQ-350 a worthwhile candidate to test on cancer patients affected by CIPN. The aim of this pilot proof-of-concept study is to assess PK/PD relationships in cancer patients with CIPN symptoms in order to determine the impact BXQ-350 has on ceramide, S1P, and inflammatory cytokine levels; thereby potentially reducing the intensity and/or duration of CIPN, improving QoL, and establishing these signaling molecules as biomarkers in future studies.

Model description
Participants will be assigned to 1 of 2 treatment arms (BXQ-350 or placebo) in a 1:1 ratio for the first two treatment cycles. At the end of the second treatment cycle, participants will be unblinded to their individual treatment assignment. Participants who received placebo will be offered 2 cycles of open-label BXQ-350. Participants who received BXQ-350 in Cycles 1 and 2 will continue to the Post-Treatment Follow-Up. If placebo participants elect to forego BXQ-350 at the time of unblinding, their participation in the study will end following an end of study visit.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing BXQ-350 in people with Neuropathy;Peripheral and Chemotherapy-induced Peripheral Neuropathy, run by Bexion Pharmaceuticals, Inc. at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 36 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Peak Plasma Concentration (Cmax) (time frame: 6 months). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05291286.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2025.
