BACKGROUND: Adalimumab is an anti-inflammatory medicine used to treat a variety of disorders, although its effectiveness in improving the clinical status of COVID-19 patients is debatable. The goal was to evaluate the efficacy of adalimumab as an alternate treatment in COVID-19 patients.

METHODS: This non-randomized pilot clinical trial study included 18 patients with severe COVID-19 status hospitalized at the Afzalipour Hospital in Kerman from February 2022 to March 2022. Patients were divided into two groups: nine patients in the control group received dexamethasone, remdesivir, and heparin in addition to supportive therapies. The case group also included nine patients who received adalimumab injection (CinnoRA®, CinnaGen, Iran) in addition to the treatment administered to the control group.

RESULTS: Although the effect of adalimumab injection on clinical factors, including mechanical ventilation required, the number of days oxygen needed, the length of stay in the intensive care unit (ICU), and saturation of peripheral oxygen (SpO2) level and respiratory rate (RR), were not significantly different between groups, the intra-group SpO2 level before and after receiving oxygen was significantly different in the case group (p ≤ 0.001 and p = 0.002). In addition, laboratory tests for lactate dehydrogenase (LDH) and C-reactive protein (CRP) revealed no statistically significant differences between the two groups. Nonetheless, a positive intra-group effect of the medication was detected on these two parameters. No short-term side effects of drug injection were observed.

CONCLUSIONS: This study demonstrated the efficacy of adalimumab as an alternate medication for improving SpO2, LDH, and CRP levels in COVID-19 patients.
