Artiva Biotherapeutics, a biotech company specializing in innovative cell therapy, has successfully raised $167 million through its initial public offering (IPO), aimed at supporting the clinical trials for their novel treatment approaches for autoimmune diseases. Initially pricing the IPO at $12 per share, which fell below the expected price range of $14 to $16 per share, Artiva adjusted by offering more shares, thus surpassing their original fundraising goal. Despite the increase in offered shares and the IPO’s success, Artiva’s shares opened flat on Nasdaq under the ticker “ARTV.”
Founded in 2019 and spun out from GC Lab Cell Corporation (now GC Cell), Artiva’s focus has shifted from its initial cancer cell therapy projects to pioneering work in autoimmune disease treatments. The company holds exclusive rights outside Asia to GC Cell’s NK cell manufacturing technology and its prominent AlloNK program. Artiva initially gained recognition in the industry with substantial funding, including a $78 million Series A financing and total fundraising of $222.4 million prior to the IPO. Major shareholders include GC Corp., which remains the largest shareholder post-IPO with a 13.5% stake, followed by 5AM Ventures, venBio, and RA Capital Management holding 8.1% each.
Artiva’s unique proposition lies in its use of allogeneic natural killer (NK) cells derived from cord blood, rather than the traditional autologous T cells or healthy donor-derived NK cells used in other therapies. This method not only enhances the scalability and cost-effectiveness of the treatment but also alleviates the need for sourcing cells from multiple donors. The therapies are designed to be frozen and readily available for shipment to treatment locations as needed, ensuring a practical approach to delivering cell therapy.
Currently, Artiva’s flagship program AlloNK is undergoing Phase 1/1b trials for systemic lupus erythematosus, a prevalent form of lupus, and is also exploring treatment possibilities for lupus nephritis in conjunction with this trial. Part of the trial includes testing the combination of AlloNK with approved antibody drugs such as Rituxan or Gazya which target B cells implicated in autoimmune diseases. The trials are designed as open-label studies and include lupus patients with and without nephritis.
Additionally, AlloNK is under investigation for other immune disorders in a basket study, which explores the treatment’s efficacy across multiple diseases sharing common biological markers. This study encompasses conditions like rheumatoid arthritis and pemphigus vulgaris among others. Artiva boasts several firsts with AlloNK, including being the first allogeneic NK cell therapy to enter clinical trials for autoimmune conditions under FDA oversight and receiving fast track designation.
The IPO proceeds are earmarked majorly for these clinical trials, with $55 million allocated specifically for the AlloNK trials in lupus. The company anticipates that early data from the studies will be available by the first half of 2025.
While Artiva advances its research on autoimmune diseases, other biotech firms are also exploring similar avenues. Kyverna Therapeutics and companies focusing on regulatory T cell-based therapies represent serious competition, yet Artiva’s first-mover advantage in utilizing NK cell technology for autoimmune diseases may provide a crucial competitive edge.
Echoing the complexities of the biotech industry, Artiva’s journey to public trading wasn’t straightforward. The company initially attempted to go public in 2021 during a fertile period for biotech IPOs but retracted due to a less favorable market by late 2022. Additionally, changes in their collaboration landscape, including the termination of a cancer research collaboration with Merck and a new partnership with Affimed in Hodgkin lymphoma, illustrate the dynamic nature of biotech collaborations and development strategies.
As Artiva looks forward, its redefined focus and the potentially ground-breaking impact of its upcoming trial results could significantly impact the treatment landscapes for autoimmune diseases, providing hope for innovative and effective therapeutic options.
