Who may be able to join

  • Must be a minimum of 16 years of age.

Who cannot join

  • The patient has a history of prior radiation or surgery to the intended surgical site.

  • The patient has moderate to severe renal impairment as indicated by a glomerular filtration rate (GFR) < 60 mL/min.
  • The patient has decreased hepatic function defined as aspartate aminotransferase (AST)/serum glutamic/oxaloacetic transaminase (SGOT) and alanine transaminase (ALT)/serum glutamic-pyruvic transaminase (SGPT) that is higher than 20% of the institution's normal laboratory limits, and/or the patient has elevated total bilirubin that is higher than 20% of the institution's normal laboratory limits.
  • The patient has unresolved acute toxicity from prior anti-cancer therapy grade 2 or higher, as graded by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0.

  • The patient has a history of fluorescein allergy.
Show all 12Show fewer
  • The patient has a history of drug-related anaphylactic or severe allergic reactions.
  • Presence or history of any hypersensitivity to bevonescein or its excipients that, in the judgment of the investigator, places the patient at increased risk for adverse effects.
  • Presence of a concurrent disease or condition that may interfere with study participation including recent (within 6 months of screening) New York Heart Association (NYHA) Class III or IV heart failure, myocardial infarction (MI) or cerebrovascular accident (CVA).
  • Presence or history of any condition that, in the view of the Investigator, places the patient at high risk of poor treatment compliance or of not completing the study.
  • Pregnant or breastfeeding at screening or planning to become pregnant (self or partner) at any time during the study.
  • Use of any Investigational Product or investigational medical device within 30 days prior to screening, or requirement for any investigational agent prior to completion of all scheduled study assessments.

Study groupRoleWhat they receive
ALM-488-002a WLR onlyExperimentalPatients with a preoperative diagnosis of malignancy will be assigned to study ALM-488-002a. All patients will receive ALM-488 infusion. Intraoperative nerve visualization will be performed using WLR only.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nerve Conspicuity

    Nerve Conspicuity will be compared between WLR and WLR with FL Overlay Using the Visualization Scoring System. The Nerve Conspicuity scale is a 4-point Likert scale where 1 is the least preferable and 4 is the most preferable.

    Measured: During surgery

  2. Length Measurement

    Nerve Length Measurement in mm will be compared between WLR and WLR with FL Overlay Using a Metric Ruler. Higher values are better than lower values.

    Measured: During Surgery

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Bevonescein, Intraoperative Visualization using White Light Reflectance (WLR) with Fluorescence (FL) Overlay and Intra-operative Visualization using White Light Reflectance (WLR) in people with Surgery, run by Alume Biosciences, Inc. at 1 site 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 7 inclusion and 12 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 8 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Nerve Conspicuity (time frame: During surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Oct 2026.
