Hillstar Bio is a biopharmaceutical company focused on developing precision immunotherapies for treating autoimmune diseases. Its innovative approach selectively targets and depletes harmful immune cells, sparing healthy ones, to address specific disease mechanisms and reduce the risks associated with chronic broad immunosuppression. The company aims to provide durable relief and immune reset for patients with autoimmune conditions, addressing unmet medical needs.

Callio Therapeutics specializes in the development of advanced antibody-drug conjugates (ADCs) for cancer treatment. Their focus is on creating multi-payload ADCs, which allow for the targeted delivery of drug combinations to tumor cells, potentially maximizing therapeutic benefits and improving patient outcomes.

Alesta Therapeutics is a biotechnology company focused on developing cancer therapies by targeting stress response pathways and metabolic dependencies that sustain cancer cell survival. It develops small molecule programs to address novel targets within chronic stress responses and synthetic lethal metabolic dependencies in cancer, with the aim of shutting down survival pathways that cancer cells rely on for growth.

Alentis Therapeutics is a clinical-stage biopharmaceutical company focused on developing therapies for cancer and fibrotic diseases, including liver fibrosis, cirrhosis, and liver cancer. It pursues CLDN1-targeted approaches, developing anti-CLDN1 antibodies and antibody-drug conjugates to modify disease progression in CLDN1-positive cancers. Founded in 2019 and based in Basel, Switzerland, the company advances programs that aim to modulate the immune response and enhance anti-tumor activity while addressing liver-related conditions.

Halda Therapeutics is a research-stage drug discovery company dedicated to developing next-generation precision medicine.
