NOVAPAK Nasal Packing in Shellfish Allergic Patients

Study Purpose

NOVAPAK is a sponge-like material made from materials found in shellfish. It is commonly used after nasal surgery or in nasal bleeding, as it promotes healing, decreases bleeding, and has antibacterial properties. Although NOVOPAK does not contain proteins or compounds known to be responsible for allergic reactions in people with a known allergy to shellfish, out of an abundance of caution, the manufacturer (Medtronic) has recommended avoidance in those with known shellfish allergy. There have been no reported allergic reactions in patients with shellfish allergy who were given chitosan bandages in emergencies (e.g. military applications). The study aims to investigate the safety of its use in patients with known shellfish allergy to improve healthcare quality and patient care support.

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT05343650
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This is a prospective interventional study to assess whether the tested product triggers an allergic reaction in patients with known-shellfish allergies. The primary objective is to assess the safety of Novapak, a chitosan-containing nasal packing material, in patients with known shellfish allergy. The study will be conducted in two phases. First, participants will undergo an allergy test

  • - Skin prick test (SPT) to crab, lobster, shrimp, oyster, clam, scallop, squid, and octopus -, and antibody levels analysis.
Second, in a controlled setting (i.e., in a hospital clinic that includes a resuscitation cart and doctors monitoring
  • - allergist and otolaryngologist), Novapak packing will be applied to the patient's skin for 30 minutes (on the anterior aspect of the patients' non-dominant arm).
Then, provided that no allergic symptoms are observed in stage 1, the patient's nose will be anesthetized with topical lidocaine, and a piece of Novapak material will be applied to the participant's nasal cavity at the level of the inferior turbinate for 15 minutes. After removal, the participant will be monitored in the clinic for an hour. Any allergic reaction will be documented, including increased nasal congestion, rhinorrhea, or pruritis. Since Novapak contains purified chitosan, the investigators hypothesizes that no allergic reactions will be demonstrated.

Arms & Interventions

Arms

Experimental: Study arm

Stage 1 After shellfish allergy is confirmed through the skin prick test and IgE analysis, Novapak packing will be applied to the patient's skin for 30 minutes on the anterior aspect of the patients' non-dominant arm. In case of pre-existing wounds, it will be applied to the other forearm. Participants will then be monitored for 1 hour, and any- reaction will be documented. In case of any symptoms of an allergic reaction, their study participation will be terminated. Stage 2 If no allergic symptoms are observed in stage 1, the patient's nose will be anesthetized with topical lidocaine. A piece of Novapak material will be applied to the participant's nasal cavity at the level of the inferior turbinate for 15 minutes. After removal, the participant will be monitored in the clinic for an hour. Any allergic reaction will be documented, including increased nasal congestion, rhinorrhea, or pruritis.

Interventions

Device: - NOVAPAK nasal packing applied to forearm
