  • Current participation in another clinical trial or product test
  • Pregnant or breast feeding
  • Residence in the same household as a subject currently enrolled in the study (due to potential blinding and compliance issues)
  • Concomitant endodontic therapy or periodontal therapy other than prophylaxis within the past 6 months
  • History of early onset periodontitis or acute necrotizing ulcerative gingivitis
  • Chronic disease with concomitant oral manifestations, such as autoimmune or immunosuppressive diseases (e.g., human immunodeficiency virus, severe combined immunodeficiency, neutropenia, juvenile arthritis, systemic lupus erythematosus, sickle cell anemia, Crohn's disease, rheumatoid arthritis, Sjögren's syndrome) or immunocompromised status due to cancer chemotherapy, hematopoietic stem cell or solid organ transplant, head and neck radiotherapy, splenectomy, chronic steroid usage

  • Tobacco use (former tobacco users may be enrolled, provided they have been tobacco-free for one year or more)

  • Subjects with urinalysis results suggestive of infection (if a subject meets this criterion, he/she may be rescreened for study participation when he/she no longer meets this exclusion criterion)
  • Medical conditions that the investigator considers significant and that may interfere with the examination or the safety of the subject
  • Chronic use (2 weeks or more) of medication known to affect periodontal status within one month of enrollment (such as ≥81mg aspirin, phenytoin, calcium antagonists such as nifedipine, NSAIDs, coumarin, cyclosporine, ≥10 mg/day atorvastatin or equivalent dose of another statin [Subramanian et al, 2013]);
  • Treatment with antibiotics within one month prior to enrollment

  • Known hypersensitivity to any component of the test or placebo products
  • Anything that, in the opinion of the investigator, would place the subject at increased risk or prevent the subject from fully complying with or completing the study -

Arms of the Study

Arm 1

Arm 2

Arm 3

Arm Type

Experimental

Placebo Comparator

No Intervention

Arm Label

BLXA4-ME oral rinse

Placebo oral rinse

No Rinse Control

Arm Description

The topical oral rinse dosage form of BLXA4-ME (also known as ClinRinse-1) will consist of drug substance prepared at a concentration of 1.0 μM in an aqueous vehicle solution

The placebo preparation will consist of formulated oral rinse without BLXA4-ME and will be identical to the test rinse in color, appearance and taste

The no-rinse control group will use no oral rinse, in order to assess the effect of the rinsing action independent of the active ingredients

Outcomes

Primary Outcome Measures

incidence of adverse events
Adverse events will be recorded throughout the study, and may include events reported by subjects or changes observed in oral cavity examinations or vital signs (assessed at baseline, Days 3, 7, 14, 21 and 28). Blood and urine will be collected for safety labs at Days 14 and 28 after product administration, and subjects will undergo close monitoring for mucosal inflammation and irritancy and development of periodontitis, using standard clinical periodontal measurements. Follow-up will also occur at 90 days to assess for adverse events.

Secondary Outcome Measures

Supragingival Plaque
Plaque will be measured using the Silness and Loe Plaque Index [Silness and Loe 1964]
Gingival Inflammation
Gingivitis will be measured using the Modified Gingival Index [Gordon et al 1985]
Gingival Bleeding
Gingival Bleeding will be assessed using the dichotomous bleeding on probing index

5. Study Description

Brief Summary
The primary objective is to evaluate the safety of an investigational compound, BLXA4-ME, topically applied as a daily oral rinse in adults with gingivitis. Safety will be assessed by the incidence of adverse events, including mucosal inflammation and irritancy and findings from safety labs. Subjects will be monitored for development of periodontitis, and oral flora will be analyzed to detect an increase in opportunistic organisms. The secondary objective is to assess preliminary efficacy of the oral rinse, by monitoring changes in the plaque index (PI), modified gingival index (MGI), bleeding on probing (BOP) and levels of interleukin -1β (IL-1β) in gingival crevicular fluid (GCF). The study comprises three groups in a randomized, placebo-controlled double-blind clinical trial design. The treatment group (1.0 μM BLXA4-ME oral rinse) and the placebo rinse group will each include 50 subjects. The no-rinse control group will consist of 25 subjects. Subjects in the treatment and placebo rinse groups will receive oral rinse (BLXA4-ME or placebo) to be applied once daily after morning teeth brushing. Safety parameters will be assessed before and after 3, 7, 14, 21, and 28 days of treatment. Efficacy parameters will be assessed before and after 14 and 28 days of treatment.
