Key Research and Development Areas
Core Therapeutic Areas
Forte Biosciences has identified autoimmune and immune-related diseases as its principal therapeutic areas. These encompasses a broad range of clinical indications where the immune system plays a central role, including:
- Autoimmune Diseases and Immune Dysregulation:
The core focus of the company is on autoimmunity. Their lead candidate, FB-102, targets CD-122—a subunit of IL-2 and IL-15 receptors—and is designed to modulate the activation and proliferation of natural killer (NK) cells and CD8+ T cells. Preclinical studies indicate that FB-102 demonstrates potentially best-in-class activity in models of graft-versus-host disease (GvHD) with survival benefits over standard therapies. The emphasis on immune pathways is indicative of a broader ambition to treat diseases where traditional immunosuppressants may fall short.

- Oncology Applications:
Although the primary thrust is in autoimmune indications, there are explorations into broadening the application of FB-102 into oncology settings. By modulating immune cell activity, the therapeutic could complement emerging immune-oncology strategies, particularly in settings where a balanced immune response is critical.

- Dermatological Indications – A Legacy Focus:
Initially, Forte Biosciences explored the potential of live biotherapeutics in dermatology through FB-401, a topical agent consisting of commensal Roseomonas mucosa aimed at treating atopic dermatitis. Despite promising tolerability and trends observed in secondary endpoints, the primary clinical endpoints were not met. This experience, however, provided critical insights and reinforced the company’s strategic redirection towards autoimmune diseases where the underlying biology of immune dysregulation could be more effectively targeted.

Current Projects and Innovations
Innovation at Forte Biosciences is anchored in a data-driven approach, which has led to significant refinements in its product pipeline:

- FB-102 Development:
The company’s lead asset, FB-102, has emerged as the centerpiece of its R&D efforts. Preclinical data have shown that FB-102 can effectively inhibit the proliferation and activation of key immune cell subsets implicated in autoimmune pathology. Early-phase clinical trials have focused on establishing the safety profile and pharmacodynamic properties of FB-102. Notably, the single ascending dose (SAD) portion of the phase 1 trial completed successfully, and multiple ascending dose (MAD) cohorts have demonstrated a favorable safety and tolerability profile in healthy volunteers, paving the way for patient-based studies later in the clinical development cycle.

- Mechanistic Innovations:
FB-102 is designed to selectively modulate the intermediate versus high affinity IL-2 receptor, a nuanced approach that preserves regulatory T cell (Treg) proliferation even while dampening effector cell responses. In nonhuman primate studies, the dosing of FB-102 led to significant reductions in markers of NK cell activity while maintaining Treg levels comparable to vehicle controls. This selective immunomodulation represents a sophisticated application of translational science, leveraging both in vitro and in vivo data to inform clinical trial design.

- Repositioning of Product Focus:
The earlier candidate, FB-401, exemplifies the company’s willingness to critically evaluate clinical data and make strategic realignments. Despite favorable secondary trends in improvement endpoints in atopic dermatitis, the failure to achieve statistical significance for the primary endpoint led to the halting of further development of FB-401. This decision, while challenging, allowed the company to reallocate resources to the more promising FB-102 program.
