Abstract Background/Aims Transient receptor potential vanilloid type 1 (TRPV1) receptor antagonists have been evaluated in clinical studies for their analgesic effects. Mavatrep, a potent, selective, competitive TRPV1 receptor antagonist has demonstrated pharmacodynamic effects consistent with target engagement at the TRPV1 receptor in a previous single-dose clinical study. The current study was conducted to evaluate the analgesic effects of a single dose of mavatrep. Methods In this randomized, placebo- and active-controlled, 3-way crossover, phase 1b study, patients with painful knee osteoarthritis were treated with a single-dose of 50 mg mavatrep, 500 mg naproxen twice-daily, and placebo. Patients were randomized to 1 of 6 treatment sequences. Each treatment sequence included three treatment periods of 7 days duration with a 7 day washout between each treatment period. The primary efficacy evaluation was pain reduction measured by the 4-h postdose sum of pain intensity difference (SPID) based on the 11-point (0-10) Numerical Rating Scale (NRS) for pain after stair-climbing (PASC). The secondary efficacy evaluations included 11-point (0-10) NRS pain scores entered into the Actiwatch between clinic visits, the Western Ontario and McMaster Universities Arthritis Index subscales (WOMAC) questionnaire, and use of rescue medication. Safety and tolerability of single oral dose mavatrep were also assessed. Results Of 33 patients randomized, 32 completed the study. A statistically significantly ( p <0.1) greater reduction in PASC was observed for mavatrep versus placebo (4-h SPID least square mean [LSM] [SE] difference: 1.5 [0.53]; p = 0.005 and 2-h LSM [SE] difference of PID: 0.7 [0.30]; p = 0.029). The mean average daily current pain NRS scores were lower in the mavatrep and naproxen treatment arm than in the placebo arm (mavatrep: 7 day mean [SD], 3.72 [1.851]; naproxen: 7 day mean [SD], 3.49 [1.544]; placebo: 7 day mean [SD], 4.9 [1.413]). Mavatrep showed statistically significant improvements as compared with placebo on the WOMAC subscales (pain on days 2 [ p = 0.049] and 7 [ p = 0.041], stiffness on day 7 [ p = 0.075]), and function on day 7 [ p = 0.077]). The same pattern of improvement was evident for naproxen versus placebo. The mean (SD) number of rescue medication tablets taken during the 7-day treatment period was 4.2 (6.49) for mavatrep treatment, 2.8 (5.42) for naproxen, and 6.3 (8.25) for placebo treatment. All patients that received mavatrep reported at least 1 treatment emergent adverse event (TEAE). Feeling cold (79%), thermohypoesthesia (61%), dysgeusia (58%), paraesthesia (36%), and feeling hot (15%) were the most common TEAEs in the mavatrep group. Total 9% patients receiving mavatrep experienced minor thermal burns. No deaths or serious AEs or discontinuations due to AEs occurred. Conclusion Overall, mavatrep was associated with a significant reduction in pain, stiffness, and physical function when compared with placebo in patients with knee osteoarthritis. Mavatrep’s safety profile was consistent with its mechanism of action as a TRPV1 antagonist. Implications Further studies are required to evaluate whether lower multiple doses of mavatrep can produce analgesic efficacy while minimizing adverse events, as well as the potential for improved patient counselling techniques to reduce the minor thermal burns related to decreased heat perception.

Abstract Background and aims: This double-blind (DB), randomized, placebo-controlled, sequential-group, multiple-ascending dose, phase 1 study evaluated safety, pharmacokinetics and pharmacodynamics of JNJ-39439335 in healthy men (part 1), and in participants with knee osteoarthritis (part 2). Methods: Both parts 1 and 2 consisted of screening (upto 21 days), 21-day DB treatment phase [eight participants/group: JNJ-39439335 (part 1: 2–50 mg; part 2: 10–50 mg): n =6; placebo: n =2] and follow-up (total study duration ~10 weeks). Results: Plasma concentrations and systemic exposure of JNJ-39439335 increased in slightly higher than dose-proportional fashion (steady-state reached by day 14). Renal excretion of JNJ-39439335 was negligible. Marked dose-related increases in pharmacodynamic heat pain assessments were observed in JNJ-39439335-treated participants, which persisted throughout the treatment with no signs of tolerance with repeated dosing. No effect on pharmacodynamic cold pain or mechanical pain assessments were seen. Effects on pharmacodynamic capsaicin-induced flare assessments in JNJ-39439335-treated participants versus placebo were consistent with effects observed with single-dose, and did not demonstrate tolerance with multiple dosing. In participants with knee osteoarthritis, significant improvements versus placebo were observed in a stair-climbing-induced pain model. All JNJ-39439335-treated participants reported ≥1 treatment-emergent adverse events (TEAE); most common (≥50% incidence) TEAEs in part 1 were feeling hot (79%), thermohypoesthesia (71%), paresthesia (58%) and feeling cold (50%), and in part 2, were minor thermal burns (50%). Conclusions: JNJ-39439335 (doses 2–50 mg) was well-tolerated, and associated with acceptable multiple-dose pharmacokinetic profile. JNJ-39439335 demonstrated sustained pharmacodynamic effects (heat pain perception, heat pain latency, capsaicin-induced flare), and an efficacy signal in participants with osteoarthritis pain. Implications: Given the efficacy signal observed and the unique safety profile, larger phase 2 studies are needed to better understand the potential of JNJ-39439335 in the treatment of chronic pain. Analgesic efficacy of lower doses administered over a longer period of time and improved patient counseling techniques to reduce the minor thermal burns can be explored to minimize the adverse events.
