A Double-Blind, Placebo-Controlled, Phase 2B Study to Assess the Efficacy and Safety of a 14-Day Dosing Regimen of 3 Doses of ATB-346 Versus Placebo, Orally Administered Once Daily to Patients Diagnosed With Osteoarthritis of the Knee

The primary objective of this study is to evaluate the efficacy of a 14-day dosing regimen of ATB-346 at doses of 150 mg, 200 mg and 250 mg compared to placebo in reducing osteoarthritis knee pain as measured by changes in the post-treatment WOMAC subscale pain score relative to each patient's pretreatment baseline WOMAC assessment.Safety will be assessed via measurements of vital signs and clinical laboratory tests at baseline and at various time points during the study, patient monitoring, and by the documentation of adverse events.

Potent anti‐inflammatory effects of an H ₂ S‐releasing naproxen (ATB‐346) in a human model of inflammation

ATB-346 is a hydrogen sulfide-releasing non-steroidal anti-inflammatory drug (H₂ S-NSAID) derived from naproxen, which in preclinical studies has been shown to have markedly reduced gastrointestinal adverse effects. However, its anti-inflammatory properties in humans compared to naproxen are yet to be confirmed. To test this, we used a dermal model of acute inflammation in healthy, human volunteers, triggered by ultraviolet-killed Escherichia coli. This robust model allows quantification of the cardinal signs of inflammation along with cellular and humoral factors accumulating within the inflamed skin. ATB-346 was non-inferior to naproxen in terms of its inhibition of cyclooxygenase activity as well as pain and tenderness. ATB-346 significantly inhibited neutrophil infiltration at the site of inflammation at 4 h, compared to untreated controls. Subjects treated with ATB-346 also experienced significantly reduced pain and tenderness compared to healthy controls. Furthermore, both classical and intermediate monocyte subsets infiltrating the site of inflammation at 48 h expressed significantly lower levels of CD14 compared to untreated controls, demonstrating a shift toward an anti-inflammatory phenotype. Collectively, we have shown for the first time in humans that ATB-346 is potently anti-inflammatory and propose that ATB-346 represents the next generation of H₂ S-NSAIDs, as a viable alternative to conventional NSAIDs, with reduced adverse effects profile.

Nonsteroidal Anti-Inflammatory Drugs and Their Neuroprotective Role After an Acute Spinal Cord Injury: A Systematic Review of Animal Models

3区 · 医学

ArticleOA

作者: Lambrechts, Mark J. ; Cook, James L.

Study Design::

Systematic review.

Objective::

Spinal cord injuries (SCIs) resulting in motor deficits can be devastating injuries resulting in millions of health care dollars spent per incident. Nonsteroidal anti-inflammatory drugs (NSAIDs) are a potential class of drugs that could improve motor function after an SCI. This systematic review utilizes PRISMA guidelines to evaluate the effectiveness of NSAIDs for SCI.

Methods::

PubMed/MEDLINE, CINAHL, PsycINFO, Embase, and Scopus were reviewed linking the keywords of “ibuprofen,” “meloxicam,” “naproxen,” “ketorolac,” “indomethacin,” “celecoxib,” “ATB-346,” “NSAID,” and “nonsteroidal anti-inflammatory drug” with “spinal.” Results were reviewed for relevance and included if they met inclusion criteria. The SYRCLE checklist was used to assess sources of bias.

Results::

A total of 2960 studies were identified in the PubMed/MEDLINE database using the above-mentioned search criteria. A total of 461 abstracts were reviewed in Scopus, 340 in CINAHL, 179 in PsycINFO, and 7632 in Embase. A total of 15 articles met the inclusion criteria.

Conclusions::

NSAIDs’ effectiveness after SCI is largely determined by its ability to inhibit Rho-A. NSAIDs are a promising therapeutic option in acute SCI patients because they appear to decrease cord edema and inflammation, increase axonal sprouting, and improve motor function with minimal side effects. Studies are limited by heterogeneity, small sample size, and the use of animal models, which might not replicate the therapeutic effects in humans. There are no published human studies evaluating the safety and efficacy of these drugs after a traumatic cord injury. There is a need for well-designed prospective studies evaluating ibuprofen or indomethacin after adult spinal cord injuries.

A proof‐of‐concept, Phase 2 clinical trial of the gastrointestinal safety of a hydrogen sulfide‐releasing anti‐inflammatory drug

Article

作者: Buret, Andre G. ; Ditrói, Tamás ; de Nucci, Gilberto ; Vaughan, David J. ; Wallace, John L. ; Muscara, Marcelo N. ; Allain, Thibault ; Feener, Troy D. ; Nagy, Peter

Background and Purpose:

ATB‐346 is a hydrogen sulfide (H2S)‐releasing anti‐inflammatory and analgesic drug. Animal studies demonstrated negligible gastrointestinal (GI) damage despite marked inhibition of COX activity and significant analgesic and anti‐inflammatory effects. In humans, ATB‐346 (250 mg once daily) was found to inhibit COX to the same extent as naproxen (550 mg twice daily).

Experimental Approach:

Two hundred forty‐four healthy volunteers completed a 2‐week, double‐blind study, taking either ATB‐346 (250 mg once daily) or naproxen (550 mg twice daily), with upper GI ulceration being examined endoscopically.

Key Results:

Forty‐two per cent of the subjects taking naproxen developed at least one ulcer (≥3‐mm diameter), while only 3% of the subjects taking ATB‐346 developed at least one ulcer. The two drugs produced comparable and substantial (>94%) suppression of COX activity. Subjects in the naproxen group developed more ulcers per subject than ATB‐346‐treated subjects and a greater incidence of larger ulcers (≥5‐mm diameter). The incidence of dyspepsia, abdominal pain, gastro‐oesophageal reflux, and nausea was lower with ATB‐346 than with naproxen. Subjects treated with ATB‐346 had significantly higher plasma levels of H2S than those treated with naproxen.

Conclusions and Implications:

This Phase 2B study provides unequivocal evidence for a marked reduction of GI toxicity of the H2S‐releasing analgesic/anti‐inflammatory drug, ATB‐346, as compared to the conventional dose of naproxen that produced equivalent suppression of COX.
