The deal is expected to close during the second quarter of 2020. In connection with the transaction and subject to closing, Correvio will apply to have its shares delisted from the Toronto Stock Exchange and Nasdaq, where shares (NASDAQ:CORV) gained 3 cents on March 16 to close at 34 cents.

Homology Medicines Inc., of Bedford, Mass., said preclinical data showed that a single administration of its PAH gene therapy, HMI-102 (AAVHSC15-PAH), reduced serum phenylalanine (Phe) concentrations to normal levels within one week in a phenylalanine murine model and that mean levels remained in the normal range, below 120 µM, over the course of the 48-week study. A corresponding increase in Tyr concentration also was observed, indicating restoration of the Phe/Tyr metabolic pathway, and administration of HMI-102 was associated with an increase in 5-HIAA and a decrease in Phe in the brain to normal levels. The findings were published in Molecular Therapy: Methods & Clinical Development.

Medivir AB, of Stockholm, said it inked a license agreement covering one of its preclinical programs with Tango Therapeutics Inc., of Cambridge, Mass., in exchange for up-front, development and commercial milestone payments, all undisclosed, and low single-digit product royalties.

Nanoviricides Inc., of Shelton, Conn., said it completed the synthesis of multiple nanoviricide drug candidates for testing following identification of virus-binding ligands associated with SARS-CoV-2. The company acquired and expanded two low-threat circulating coronaviruses in its BSL2 lab and expanded them to enable testing of drug candidates. One of those, NL63, uses the same ACE2 receptor on human cells as SARS-CoV-2 but does not cause similarly severe disease in humans. Effectiveness of test candidates in the cell culture studies against coronaviruses would provide a rationale for effectiveness against SARS-CoV-2, according to Nanoviricides. The company is seeking to establish collaborations to enable additional testing of its drug candidates against the current coronavirus. In the meantime, Nanoviricides expects to begin testing its drug candidates against the BSL2 coronavirus strains in its BSL2 virology lab. Despite the plummeting markets, on March 16 the company’s shares (NYSE American:NNVC) gained 6%, adding 42 cents to close at $7.28.

Pharmamar SA, of Madrid, said that in vitro studies of Aplidin (plitidepsin) on the human coronavirus HCoV-229E, which has a multiplication and propagation mechanism similar to the SARS-CoV-2 virus that causes COVID-19, were positive, with potency of the nanomolar order. The studies, performed at the National Biotechnology Centre of the Spanish National Research Council, confirmed the hypothesis that the therapeutic target of Aplidin, elongation factor 1 alpha 2, is key to the multiplication and spread of the coronavirus. Pharmamar plans to contact regulatory authorities to discuss the possibility of conducting studies of Aplidin, originally advanced to treat cancer, on individuals with COVID-19.

Protalix Biotherapeutics Inc., of Carmiel, Israel, said it agreed to conduct a feasibility study with Kirin Holdings Co. Ltd., of Tokyo, to evaluate production of a complex protein using its Procellex plant cell-based protein expression system. Kirin agreed to provide research funding for Protalix scientists to conduct cell line engineering and protein expression studies on the target protein. If the study succeeds, Kirin and Protalix expect to discuss a licensing agreement of Procellex to Kirin to continue the program’s development.

Spherix Inc., of New York, said it completed its name change to Aikido Pharma Inc. and began trading on Nasdaq under the ticker AIKI.

Therapeuticsmd products include Bijuva for reducing moderate to severe hot flashes and Imvexxy, an estrogen hormone for treating menopausal symptoms.

Twist Bioscience Corp., of South San Francisco, Calif., announced the availability of research-use only target enrichment next-generation sequencing panels for viral detection and characterization of samples from patients testing positive for SARS-CoV-2, which causes COVID-19. The panels can be used for environmental monitoring and surveillance testing, while also providing insight into full sequence information to track viral evolution and strain origin. The target enrichment panels are in three reaction sizes for various workflows, with synthetic double-stranded DNA probes covering the length of the SARS-CoV-2 virus. Next-generation sequencing offers high-throughput, specific identification of infections in several sample types, including blood, nasal swab and feces. For viral infections, obtaining genetic material sufficient for sequencing can be a challenge due to low levels of virus often present. For those infections, target enrichment using DNA-based hybridization probes to isolate specific sequences out of a mixed genomic sample can increase the sensitivity and specificity of NGS-based efforts.

Earlier this year, Xavier Saelens (the VIB-UGent Center for Medical Biotechnology) said it discovered a single-domain antibody (VHH) capable of binding the SARS-CoV-2 spike protein of COVID-19. The lab team said it established that Fc fusions of the VHH can neutralize pseudotyped SARS-CoV-2 and that the neutralizing VHH can be produced in large-scale production processes common in the biopharmaceutical industry.

Xortx Therapeutics Inc., of Calgary, Alberta, is researching the use of XRx-101, a formulation of oxypurinol, to treat acute kidney and lung injury accompanying coronavirus infection and specifically for COVID-19 infection. The company, which reviewed recent studies characterizing the outbreak of COVID-19 in mainland China, reported illustrating that acute kidney injury and acute pulmonary injury are key factors in the most serious cases of COVID-19 hospitalization and death. Xortx said it plans to manufacture and submit INDs for XRx-008’s planned phase III trial in autosomal dominant polycystic kidney disease.
