Artelo Biosciences, Inc. (ARTL)  has formally requested the withdrawal of its recently effective registration statement for a planned securities offering, signaling a pause in its capital-raising efforts.

On Friday, the company submitted a request under Rule 477 of the Securities Act of 1933 to withdraw its Form S-1, initially filed with the U.S. Securities and Exchange Commission on March 20 and declared effective on March 25.

Artelo Pauses Proposed Securities Offering

Artelo stated that it does not plan to move forward with the proposed securities offering at this time. The company emphasized that no shares were issued or sold under the registration statement, and it intends to revisit capital-raising options in the future when conditions are more favorable.

Following the update, Artelo Biosciences stock traded over 420% higher on Friday afternoon. On Stocktwits, retail sentiment around the stock changed to ‘extremely bullish’ from ‘bullish’ territory the previous day amid ‘extremely high’ message volume levels. 

Additionally, the company announced a new private placement involving the sale of more than 3.18 million shares or equivalent pre-funded warrants. The transaction is expected to finalize around March 30, and the company expects gross proceeds of approximately $11 million.

Strategic Expansion Initiative

On Thursday, Artelo announced plans to explore a new application for its ART27.13 compound. The therapy targets muscle preservation in patients undergoing glucagon-like peptide-1 (GLP-1) receptor agonist treatment to address lean body mass loss. 

The initiative builds on multiple promising developments. ART27.13 demonstrated protective effects on muscle in the CAReS trial, showing increased lean body mass and enhanced physical activity in cancer anorexia and cachexia patients.

Artelo Biosciences is a clinical-stage pharmaceutical company focused on treatments for cancer, pain, dermatologic, and neurological conditions.

ARTL stock has gained over 170% year-to-date.
