NanoViricides shares jump on it’s potential Covid-19 drug

NanoViricides announces safety results from drug candidates against SARS-CoV-2

NanoViricides (NNVC) announced that safety and tolerability of the drug candidates it is developing against SARS-CoV-2 to treat COVID-19 spectrum of diseases was observed in an animal model.

The company said the nanoviricides drug candidates tested in this safety/tolerability study have previously shown strong effectiveness against lung infection by a SARS-CoV-2 like coronavirus, namely, hCoV-NL63, in an animal study as previously reported by the company.

Three different drug candidates at three different dosage levels and vehicle control were administered to separate groups of mice intravenously in the Safety-Tolerability study.

Clinical observations and gross post-mortem studies have been completed.

The tested drug candidates were safe and well tolerated, thereby clearing the path for further development towards a treatment for SARS-CoV-2 infection that has caused the current COVID-19 pandemic.

Nanoviricides are designed to act by a novel mechanism of action, trapping the virus particle.

Antibodies, in contrast, only label the virus for other components of the immune system to take care of. It is well known that the immune system is not functioning properly at least in severe COVID-19 patients.

Additionally, it is well known that viruses escape antibody-drugs via mutations.

The company’s “nanoviricide” drug candidates, in contrast, are designed to be broad-spectrum, and therefore virus escape by mutations is expected to be unlikely.

In this Safety/Tolerability Study, there were no clinical signs of immune or allergic reactions such as itching, biting, twitching, rough coat, etc.

Further, there were no observable changes in any organs including large intestine or colon on post mortem in gross histology. The only reportable changes observed were, in the high dosage groups of two of the three drug candidates tested, associated with the non-absorption of water, in the colon.

This is consistent with the clinical observation of very loosened stools in the same groups. In clinical usage, the drug candidates are not anticipated to be administered in such high levels. The objective of this study was to discover the dosage level at which such an effect may occur.

Sixteen mice in each group were administered one of the three drug candidates at one of the three dose levels, and additionally, one group was administered vehicle control, for seven days by daily tail-vein intravenous infusion in this blinded study with additional evaluations on eighth day.

This non-GLP safety/tolerability study was conducted under GLP-like conditions.

The company believes that loose or very loose stools at very high dosages in such a study is an expected and acceptable side effect of the polyethylene glycol, or PEG, moiety, which forms the backbone of the nanoviricides drug candidates.

PEG is used prior to colonoscopy in humans to promote loose stools and internal cleaning of the intestines, by causing non-absorption of water.

The company has previously reported that these drug candidates have shown strong effectiveness in a lethal lung infection model in rats using a coronavirus that uses the same ACE2 receptor as SARS-CoV-2 which causes COVID-19, namely hCoV-NL63.

The company has found that hCoV-NL63, which causes a milder disease than SARS-CoV-2, causes substantially similar clinical pathology in this efficacy animal model as has been reported for SARS-CoV-2 associated lung infections in humans. In this previously reported lethal direct-lung-infection model efficacy study, animals in all groups developed lung disease which later led to multi-organ failures, a clinical pathology resembling that of the SARS-CoV-2.

Reduction in loss of body weight at day seven was used as the primary indicator of drug effectiveness. Rats were infected directly into lungs with lethal amounts of hCoV-NL63 virus particles and then different groups were treated separately with five different nanoviricides drug candidates, remdesivir as a positive control, and the vehicle as a negative control.

The treatment was intravenous by tail-vein injection once daily for five days, except in the case of remdesivir wherein it was by tail-vein injection twice daily. In this efficacy study, animals treated with the five different nanoviricides showed significantly reduced body weight loss.

The body weight loss in female animals ranged from only 3.9% to 11.2% in the different nanoviricide-treated groups, as compared to 20% in vehicle-treated control group, and 15.2% in a remdesivir-treated group. The body weight loss in male animals ranged from 8% to 10.9% in the different nanoviricides-treated groups, as compared to 25% in the vehicle-treated control group, and 18.6% in remdesivir-treated group.

Smaller numbers mean less loss in body weight compared to starting body weight in the group, and indicate greater drug effectiveness.

The effectiveness of nanoviricide drug candidates in the lung-infection model is consistent with the effectiveness observed in cell culture studies against infection of both hCoV-NL63, which was used in the efficacy study, and hCoV-229E, another circulating coronavirus that uses a distinctly different receptor, namely APN. Prior to filing for human clinical trials,

NanoViricides plans on requesting a pre-IND Meeting with the FDA for regulatory guidance.

NNVC is up $2.04 to $8.97.

National General sold for $4 billion

Allstate to acquire National General for $34.50 per share, in cash

Allstate (ALL) has agreed to acquire National General (NGHC) for approximately $4B in cash, or $34.50 per share.

The companies said in a release, “The transaction is expected to close in early 2021, subject to regulatory approvals and other customary closing conditions.

National General sold for $4B

National General provides a wide range of property-liability products through independent agents with a significant presence in non-standard auto insurance.

The company also has attractive Accident and Health and Lender-Placed Insurance businesses.

Gross premiums written were $5.6 billion, which generated operating income of $319 million in 2019.

National General shareholders will receive $32.00 per share in cash from Allstate, plus closing dividends expected to be $2.50 per share, providing $34.50 in total value per share.

Allstate will fund the share purchase by deploying $2.2 billion in combined cash resources and, subject to market conditions, issuing $1.5 billion of new senior debt.

Allstate expects to maintain its current share repurchase program.

National General’s board of directors has approved the transaction, which includes customary terms and conditions, including a breakup fee of $132.5 million.

A voting agreement has also been signed with entities controlling 40% of National General’s common shares to vote for the transaction.

MSD Capital, which owns approximately 7.4% of National General’s outstanding common shares, also supports the transaction.
