MiNK Therapeutics is a clinical-stage biopharmaceutical company leading the charge in the discovery, development, and commercialization of allogeneic, off-the-shelf invariant natural killer T (iNKT) cell therapies. With its innovative platform and manufacturing capabilities, MiNK is poised to revolutionize the treatment landscape for cancer and other immune-mediated diseases.
Business Overview and History
Incorporated in 2017, MiNK Therapeutics was founded with the vision of harnessing the unique properties of iNKT cells to develop transformative therapies. The company's proprietary platform is designed to facilitate scalable and reproducible manufacturing for off-the-shelf delivery of these iNKT cell therapies. iNKT cells are a distinct T-cell population that combine the durable memory responses of T-cells with the rapid cytolytic features of natural killer (NK) cells, making them an ideal candidate for allogeneic, off-the-shelf cell therapies.
In 2021, MiNK entered into an Intellectual Property Assignment and License Agreement with Agenus, which assigned the company certain patent rights and know-how related to the iNKT cell platform. This provided MiNK with the exclusive rights to research, develop, manufacture, and commercialize the licensed technology in the field. Additionally, MiNK entered into an Amended and Restated Intercompany Services Agreement with Agenus, under which Agenus provides various general and administrative and research and development services to MiNK.
A significant milestone for the company came in October 2021 when MiNK completed its initial public offering, raising approximately $39.8 million in net proceeds. This infusion of capital provided the company with additional resources to advance its clinical programs and platform development.
In 2022, MiNK faced a challenge when it learned that the Walloon Region in Belgium had obtained a default judgment against the company for repayment of a $2.09 million advance related to a discontinued research program. However, MiNK was able to reduce the recorded liability and recorded a gain of $2.7 million as a result.
Since then, MiNK has made significant strides in advancing its pipeline. The company's lead program, agenT-797, is an off-the-shelf, allogeneic, native iNKT cell therapy that has demonstrated promising results in both monotherapy and combination settings. In a Phase 1 trial, agenT-797 achieved durable disease control in heavily pre-treated patients across various solid tumor types, including non-small cell lung cancer, testicular cancer, and gastric cancer. Notably, the median progression-free survival exceeded six months, with approximately 30% of patients experiencing durable disease stabilization.
Building on these positive results, MiNK is currently evaluating agenT-797 in a Phase 2 trial in second-line advanced gastric cancer, in combination with Agenus' botensilimab and balstilimab, as well as standard-of-care chemotherapy. The company has also initiated a Phase 1 trial to explore the potential of agenT-797 in preventing and treating acute graft-versus-host disease (GvHD) following allogeneic hematopoietic stem cell transplantation.
In addition to agenT-797, MiNK's pipeline includes next-generation allogeneic, engineered iNKT cell programs, such as MiNK-215, a tumor stromal targeting FAP-CAR-iNKT therapy, and MiNK-413, a BCMA-targeted CAR-iNKT program. These innovative therapies leverage the unique properties of iNKT cells to address unmet needs in solid tumors and hematological malignancies.
Product Segments and Pipeline
MiNK's product portfolio is centered around its proprietary iNKT cell therapies, which serve as master regulators of immune response, possessing the killing power of NK cells and the memory of T-cells. The company's manufacturing platform enables the infusion of these cells in billion-fold quantities, equipping the immune system to combat cancer and other life-threatening diseases.
The clinical development of agenT-797 is advancing in multiple therapeutic areas, including a Phase 2 trial in second-line gastric cancer and viral acute respiratory distress syndrome (ARDS). In a completed Phase 1 trial in solid tumor cancers, agenT-797 demonstrated durable clinical benefits with a tolerable safety profile across various heavily pre-treated solid tumors. A randomized, Phase 2 investigator-sponsored trial is actively enrolling to evaluate agenT-797 in combination with other therapies in patients with previously treated, advanced esophageal, gastric, or gastroesophageal junction adenocarcinoma.
MiNK's engineered iNKT cell programs, MiNK-215 and MiNK-413, have shown promising preclinical results in solid tumor and hematological malignancy models, with data presented at various scientific conferences. These programs represent the next generation of the company's allogeneic, engineered iNKT therapies.
Financial Overview
For the fiscal year ended December 31, 2023, MiNK reported no revenue and a net loss of $22.46 million. The company's operating cash flow was -$15.76 million, with a free cash flow of -$15.84 million.
In the most recent quarter (Q3 2024), MiNK reported no revenue and a net loss of $1.81 million. This represents a significant improvement from the net loss of $5.12 million in Q3 2023, primarily due to decreases in research and development and general & administrative expenses.
MiNK Therapeutics reported a net loss of $8.3 million, or $0.22 per share, for the nine months ended September 30, 2024, compared to a net loss of $17.0 million, or $0.50 per share, for the same period in 2023. The company's cash and cash equivalents balance stood at $6.3 million as of September 30, 2024.
Research and development expenses decreased by 84% to $0.54 million in the third quarter of 2024, compared to $3.43 million in the same period of 2023. This reduction was primarily due to a $1.8 million gain from the forgiveness of certain liabilities and decreased costs associated with clinical trials and preclinical activities. General and administrative expenses also decreased by 35% to $1.16 million in the third quarter of 2024, compared to $1.80 million in the third quarter of 2023, primarily due to decreased personnel costs.
Despite the ongoing losses, MiNK has made significant progress in reducing its operating burn by nearly 60% compared to the same period last year. This improvement is largely attributable to the company's focus on manufacturing efficiencies, cost containment measures, and external funding of its clinical programs.
Liquidity
As of September 30, 2024, MiNK had a debt-to-equity ratio of -0.263 and cash and cash equivalents of $6.33 million.
