Abstract

Plitidepsin, a marine-derived cyclic-peptide, inhibits SARS-CoV-2 replication at nanomolar concentrations by targeting the host protein eukaryotic translation elongation factor 1A. Here, we show that plitidepsin distributes preferentially to lung over plasma, with similar potency against across several SARS-CoV-2 variants in preclinical studies. Simultaneously, in this randomized, parallel, open-label, proof-of-concept study (NCT04382066) conducted in 10 Spanish hospitals between May and November 2020, 46 adult hospitalized patients with confirmed SARS-CoV-2 infection received either 1.5 mg (n = 15), 2.0 mg (n = 16), or 2.5 mg (n = 15) plitidepsin once daily for 3 d. The primary objective was safety; viral load kinetics, mortality, need for increased respiratory support, and dose selection were secondary end points. One patient withdrew consent before starting procedures; 45 initiated treatment; one withdrew because of hypersensitivity. Two Grade 3 treatment-related adverse events were observed (hypersensitivity and diarrhea). Treatment-related adverse events affecting more than 5% of patients were nausea (42.2%), vomiting (15.6%), and diarrhea (6.7%). Mean viral load reductions from baseline were 1.35, 2.35, 3.25, and 3.85 log10 at days 4, 7, 15, and 31. Nonmechanical invasive ventilation was required in 8 of 44 evaluable patients (16.0%); six patients required intensive care support (13.6%), and three patients (6.7%) died (COVID-19-related). Plitidepsin has a favorable safety profile in patients with COVID-19.

Abstract

Plitidepsin is a marine-derived cyclic-peptide that inhibits SARS-CoV-2 replication at low nanomolar concentrations by the targeting of host protein eEF1A (eukaryotic translation-elongation-factor-1A). We evaluated a model of intervention with plitidepsin in hospitalized COVID-19 adult patients where three doses were assessed (1.5, 2 and 2.5 mg/day for 3 days, as a 90-minute intravenous infusion) in 45 patients (15 per dose-cohort). Treatment was well tolerated, with only two Grade 3 treatment-related adverse events observed (hypersensitivity and diarrhea). The discharge rates by Days 8 and 15 were 56.8% and 81.8%, respectively, with data sustaining dose-effect. A mean 4.2 log10 viral load reduction was attained by Day 15. Improvement in inflammation markers was also noted in a seemingly dose-dependent manner. These results suggest that plitidepsin impacts the outcome of patients with COVID-19.

Abstract

A sensitive bio-analytical assay for the depsipeptide aplidine in plasma has been modified and tested for human whole blood samples. The adapted method is based on reversed-phase liquid chromatography and fluorescence detection of the trans-4'-hydrazino-2-stilbazole derivative of the analyte. Aplidine is isolated from the matrix by solid-phase extraction on an octadecyl modified silica stationary phase. After evaporation of the acetone eluate, the derivatization with the hydrazino reagent is performed in a water-acetonitrile mixture at pH = 4. The reaction mixture is injected directly into the chromatograph and the analyte is quantified by fluorescence detection at 410 and 560 nm for excitation and emission, respectively. The method has been validated in the 2-100 ng/mL range, with 2 ng/mL being the lower limit of quantification. Precision and accuracy both meet the current requirements for a bioanalytical assay. The stability of aplidine in whole blood at ambient temperature and at 37 degrees C is limited; recoveries in the range 60-85% were observed after 7 h. Further, adequate stability of aplidine in plasma at -80 and -20 degrees C for 35 months could now be demonstrated., (Copyright 2003 John Wiley & Sons, Ltd.)

Abstract

The sea, covering 70% of the Earth's surface, offers a considerably broader spectrum of biological diversity than terra firma. Containing approximately 75% of all living organisms, the marine environment offers a rich source of natural products with potential therapeutic application. Marine organisms have evolved the enzymatic capability to produce potent chemical entities that make them promising sources of innovative cytotoxic compounds. Prominent in the identification and development of novel anti-cancer agents from marine sources is the Spanish biotechnology company, PharmaMar, which currently has a large number of oncology products in late preclinical and clinical development. These include: ecteinascidin-743 (ET-743), a marine-derived antitumor agent isolated from the Caribbean tunicate, Ecteinascidia turbinata; aplidine (Aplidin), a cyclopeptide cytotoxic agent derived from the Mediterranean tunicate, Aplidium albicans; kahalalide F, a depsipeptide isolated from the Hawaiian mollusc, Elysia rufescens; and ES-285, a molecule isolated from the mollusc, Spisula polynyma. Many of these innovative compounds have novel mechanisms of anti-tumor action that have yet to be fully elucidated.
