Using Bevonescein to Improve Nerve Visualization During Head and Neck Surgery

ALM-488 for Intra-Operative Visualization of Nerves in Head and Neck Surgery

PHASE3 · Alume Biosciences, Inc. · NCT05377554

This study is testing if a new tool called Bevonescein can help surgeons see nerves more clearly during head and neck surgeries to make the procedures safer.

What this trial studies

This clinical trial evaluates the use of Bevonescein, a visualization adjunct, to enhance the real-time structural delineation of major nerves during head and neck surgeries such as parotidectomy and thyroidectomy. It is a multicenter, open-label, blinded, randomized controlled study designed to assess the effectiveness of this intervention in improving surgical outcomes. Participants will be monitored for their ability to comply with study procedures and provide informed consent. The study aims to provide surgeons with better tools for nerve identification, potentially reducing complications.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 16 and older who are scheduled for parotidectomy, thyroidectomy, or cervical neck dissection.

Not a fit: Patients not undergoing head and neck surgery or those under 16 years of age may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved surgical outcomes and reduced nerve damage during head and neck surgeries.

How similar studies have performed: Other studies have shown promise in using visualization adjuncts for nerve identification, suggesting potential success for this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Must be a minimum of 16 years of age.
2. Must be planning to undergo surgery in the Head and Neck.
3. The study participant's primary surgical treatment is parotidectomy or thyroidectomy (unilateral or bilateral) or cervical neck dissection.
4. Willing and able to provide written assent as required and written informed consent by a legally authorized representative after the nature of the study has been explained, and prior to any research-related procedures.
5. Willing and able to comply with all study procedures.
6. Sexually active patients must be willing to use an acceptable method of contraception (e.g., double barrier method) while participating in the study and for 30 days after receiving the last dose of ALM-488.
7. Females of childbearing potential must have a negative pregnancy test at screening and be willing to have additional pregnancy tests during the study. Females considered not of childbearing potential include those who have been in menopause at least 2 years, or had bilateral tubal ligation at least 1 year prior to screening, or who have had total hysterectomy.

Exclusion Criteria:

1. The patient has a history of prior radiation or surgery to the intended surgical site.
2. The patient has abnormal cardiac rhythm not controlled with medication.
3. The patient has moderate to severe renal impairment as indicated by a glomerular filtration rate (GFR) \< 60 mL/min.
4. 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.
5. 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. Alopecia, neuropathy ≤ Grade 2, as well as other non- acute and stable anti-cancer therapy toxicities are acceptable.
6. The patient has a history of fluorescein allergy.
7. The patient has a history of drug-related anaphylactic or severe allergic reactions.
8. Presence or history of any hypersensitivity to ALM-488 or its excipients that, in the judgment of the investigator, places the patient at increased risk for adverse effects.
9. Presence of a concurrent disease or condition that may interfere with study participation including recent (within 6 months of screening) NYHA Class III or IV heart failure, myocardial infarction (MI) or cerebrovascular accident (CVA).
10. 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.
11. Pregnant or breastfeeding at screening or planning to become pregnant (self or partner) at any time during the study.
12. 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.
