Research and Development Focus

Current Therapeutic Areas
Nimbus Therapeutics has strategically concentrated its R&D efforts on several major therapeutic areas that address urgent and unmet medical needs. These areas include:

1. Oncology:
- Nimbus has positioned itself as a key player in the oncology space by targeting intracellular kinases that regulate immune responses and tumor growth. A prime example is the clinical-stage program focused on hematopoietic progenitor kinase 1 (HPK1), a target intricately linked with T-cell activation and anti-tumor immunity.
- Additionally, the company is progressing preclinical initiatives aimed at targeting oncogenic drivers such as Werner syndrome helicase (WRN), which plays a role in cancer cell proliferation and genomic stability. The exploration of novel inhibitors in this space is designed to address resistance mechanisms that limit the efficacy of traditional chemotherapeutics.

2. Immunology and Autoimmune Disorders:
- Another significant pillar of Nimbus’s R&D is in autoimmune and inflammatory diseases. The clinical-stage portfolio includes programs against tyrosine kinase 2 (TYK2), with candidates that have shown promise for conditions like psoriasis, psoriatic arthritis, and other immune-mediated diseases.
- Nimbus is also advancing preclinical programs that offer the potential to modulate innate immunity pathways. For example, discovery programs targeting salt-inducible kinase (SIK) and cyclic GMP-AMP synthase (cGAS) evidence a clear intent to harness the immune system to mediate anti-inflammatory responses.

3. Metabolic Diseases:
- Beyond oncology and immunology, Nimbus is investing in metabolic disease research, specifically targeting pathways regulated by enzymes such as 5' AMP-activated protein kinase (AMPK). The company’s work in this area is geared toward unlocking new small molecule activators that could combat obesity, diabetes, and other metabolic disorders.

In summary, Nimbus Therapeutics’ current therapeutic focus spans a broad spectrum that includes oncology, autoimmune/inflammatory diseases, and metabolic disorders—each area linked by the common thread of targeting difficult-to-drug proteins with innovative small molecule modulators.

Key Projects and Pipeline
Nimbus has developed a diversified and robust pipeline characterized by both clinical-stage and preclinical candidates. Key projects include:

1. HPK1 Inhibitor for Cancer:
- Nimbus is advancing NDI-101150, a selective and oral HPK1 inhibitor, now in Phase 1/2 clinical trials for advanced solid tumors. Clinical updates have shown promising signs of tumor growth inhibition, immune activation (including increased activated CD8+ T cells and dendritic cell infiltration), and even partial and complete responses in certain patients.
- Detailed data have been presented at high-profile conferences such as the American Society of Clinical Oncology (ASCO) Annual Meeting and the Society for Immunotherapy of Cancer (SITC), highlighting both its clinical efficacy and tolerable safety profile.

2. TYK2 Inhibitor Programs:
- Nimbus’s TYK2 program is another core component of its portfolio, particularly aimed at treating autoimmune conditions like psoriasis and psoriatic arthritis. The program involves allosteric inhibitors that target the TYK2 pseudokinase domain, providing high selectivity and a differentiated safety profile compared to other Janus kinase (JAK) inhibitors.
- Clinical data support the advanced efficacy of these molecules, with positive outcomes in Phase 2b trials, and set the stage for a subsequent Phase 3 program in psoriasis.

3. Preclinical Initiatives in Innate Immunity:
- Expanding beyond the established targets, Nimbus is actively developing discovery programs aimed at modulating innate immune pathways. The targeting of SIK and cGAS represents a promising strategy to treat highly prevalent autoimmune conditions by leveraging structure-based drug design to achieve potent and selective inhibition.
- Such preclinical projects underpin the company’s strategy to broaden its therapeutic reach while continuously validating its computational tools in new biological contexts.

4. Oncology Program Targeting WRN:
- In addition to HPK1, Nimbus is preparing to initiate IND-enabling studies for an oncology program targeting Werner syndrome helicase (WRN). This candidate is expected to provide a novel mechanism to impair tumor cell proliferation by interfering with DNA repair processes.

5. Metabolic Disease Partnerships:
- Nimbus is also collaborating with major industry players like Eli Lilly to develop targeted therapies that activate AMPK, aimed at treating a broad range of metabolic disorders. Under this collaboration, Nimbus leads the initial research phase, while Lilly assumes development and commercialization responsibilities.
- These projects underscore the strategic diversification of the pipeline, ensuring that the company can address multiple disease categories through innovative therapeutic mechanisms.

Collectively, the pipeline of Nimbus Therapeutics is both broad and deep, reflecting the company’s commitment to pioneering treatments across multiple high-impact disease areas.
