DNA Immunotherapy (INO-3107) Results in Long-Term Surgery Reduction in RRP.
Observational study in The Laryngoscope, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the long-term safety and clinical effect of INO-3107 immunotherapy in adults with recurrent respiratory papillomatosis (RRP).
methodsRRP-002 was a retrospective, observational extension study that followed patients enrolled in the 52-week RRP-001 study. Patients with moderate to severe juvenile or adult-onset RRP who had undergone ≥ 2 surgical interventions in the year preceding dosing were eligible for enrollment in RRP-001. Participants underwent surgical debulking within 14 days prior to initial dosing and then received INO-3107 on Day 0, Weeks 3, 6, and 9. Efficacy assessments during RRP-002 follow-up were the frequency of surgical interventions and alternative medication use. The safety evaluation included reported serious adverse events (SAEs).
resultsTwenty-eight (28) of 32 participants from the 52-week RRP-001 study were enrolled in RRP-002. The median follow-up time for RRP-002 was 1.8 years (range: 1.2-2.4 years) for a total median assessment time of 2.8 years (range: 1.0-3.5 years). There were no SAEs or long-term safety concerns identified. The mean number of surgeries was reduced from 4.1 in the pre-treatment period to 1.7 in the first year post-INO-3107 treatment (Year 1) to 0.9 in the second year (Year 2). The complete response rate (0 surgeries per year) increased from 28% (9/32) in Year 1 to 50% (14/28) in Year 2.
conclusionINO-3107 is well tolerated and provides a continued clinical effect against HPV-6 and 11 RRP that results in further reduction of the surgical burden observed in Year 1. These data support the role of INO-3107 immunotherapy for adult patients with RRP. LEVEL OF EVIDENCE: III.
