Its common stock trades on Nasdaq under the ticker symbol CGEM. Across its public communications, the company emphasizes a clinical-stage portfolio and a rigorous scientific approach, with the goal of creating new standards of care for patients living with serious autoimmune and oncologic diseases.
Core scientific and therapeutic focus
According to multiple company disclosures and press releases, Cullinan’s work is anchored in a deep understanding of oncology, immunology, and translational medicine. The company states that it creates differentiated ideas, identifies appropriate targets, and selects modalities that can translate into transformative therapeutics. A central theme across its programs is the use of bispecific T cell engagers to redirect a patient’s own T cells against disease-driving cells.
Cullinan highlights expertise in T cell engagers that bind both an immune cell target (such as CD3 on T cells) and a disease-associated target (such as CD19, FLT3, or BCMA). This approach is reflected in several of its named clinical and preclinical assets, which the company describes as part of a diversified, clinical-stage portfolio.
Key programs in autoimmune diseases
A major pillar of Cullinan’s strategy is the application of T cell engagers to autoimmune diseases. The company has disclosed several programs in this area:
- CLN-978: A CD19xCD3 bispecific T cell engager that the company describes as novel, differentiated, and highly potent. CLN-978 is being developed for autoimmune diseases including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Sjögren’s disease (SjD). Cullinan reports that CLN-978 is engineered for very high-affinity binding to CD19 to efficiently target B cells, including those with low CD19 expression, and that it is designed as a small (approximately 65 kDa) molecule containing two single-chain variable fragments and a single-domain antibody to human serum albumin to extend serum half-life.
- The company has presented preclinical data showing that CLN-978 led to rapid and deep B cell depletion in vitro and in vivo in multiple autoimmune disease models. In nonhuman primates, subcutaneous administration produced dose-dependent B cell depletion in blood and multiple tissues, including bone marrow and lymph nodes. In a murine model of SLE, CLN-978 treatment reduced circulating B cells, anti-dsDNA IgG levels, and IgG deposition in the kidney, which the company interprets as evidence of a disease-modifying effect in both peripheral blood and affected tissues.
- Cullinan is advancing CLN-978 through its OUTRACE clinical program, which includes the OUTRACE RA, OUTRACE SLE, and OUTRACE SjD studies. Company updates describe these as Phase 1 studies enrolling and treating patients across all three indications, with a focus on safety, B cell depletion, biomarker data, and preliminary clinical activity.
- Velinotamig: Described as a BCMAxCD3 bispecific T cell engager for autoimmune diseases. Cullinan licensed velinotamig from Genrix Bio and has stated that Genrix initiated a Phase 1 study in China in patients with autoimmune diseases. Cullinan intends to use data from that study to accelerate global development and has indicated that, after completion of the Genrix Phase 1 trial, it will conduct all further development of velinotamig in autoimmune diseases.
Across these programs, Cullinan emphasizes the potential of T cell engagers to achieve deep B cell depletion and to address underlying disease mechanisms in autoimmune conditions, rather than only treating symptoms, based on its preclinical and early clinical data.
Oncology programs and cancer focus
In oncology, Cullinan is developing therapies that target hematologic malignancies and genetically defined subsets of solid tumors. The company’s public disclosures highlight several key assets:
- CLN-049: A FLT3xCD3 bispecific T cell engager designed to target FLT3-expressing leukemia cells. CLN-049 is being studied in patients with relapsed/refractory acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), as well as in patients with AML and measurable residual disease (MRD). Company reports describe CLN-049 as binding both mutated and non-mutated FLT3, allowing targeted action regardless of FLT3 mutational status and making the investigational treatment potentially applicable to a broad AML population.
- Phase 1 studies of CLN-049 are described as open-label, multicenter, first-in-human, multiple ascending dose trials evaluating safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy in relapsed/refractory AML or MDS, along with a parallel Phase 1 study in AML with MRD. Cullinan has reported anti-leukemic activity, including complete responses and composite complete responses in heavily pretreated AML patients, with responses observed regardless of baseline genetic risk and in patients with TP53-mutated AML.
- CLN-049 has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for the treatment of relapsed/refractory AML. Company communications note that development will proceed under this designation, with dose escalation ongoing and expansion cohorts planned.
- Zipalertinib (CLN-081/TAS6417): An orally available small molecule described as a next-generation, irreversible EGFR tyrosine kinase inhibitor designed to target activating EGFR mutations, particularly EGFR exon 20 insertion (ex20ins) mutations, while sparing wild-type EGFR. Zipalertinib is being developed in collaboration with Taiho Oncology, Inc. and Taiho Pharmaceutical Co., Ltd. for patients with non-small cell lung cancer (NSCLC) harboring EGFR ex20ins or other uncommon EGFR mutations.
- Zipalertinib has received Breakthrough Therapy Designation from the FDA. Taiho and Cullinan have reported a rolling New Drug Application (NDA) submission to the FDA seeking accelerated approval for patients with locally advanced or metastatic NSCLC with EGFR ex20ins mutations who have previously received platinum-based chemotherapy. The NDA is supported by data from the REZILIENT1 Phase 1/2 trial. Additional data have been presented from the REZILIENT2 Phase 2b trial, including a cohort with active brain metastases, where intracranial and systemic antitumor activity was observed.
Through these oncology programs, Cullinan positions itself as using immuno-oncology approaches and targeted therapies to address areas of high unmet need, such as relapsed/refractory AML, MDS, and EGFR-mutated NSCLC.
Pipeline strategy and portfolio characteristics
In its public descriptions, Cullinan notes that it has strategically built a diversified portfolio of clinical-stage assets that either inhibit key drivers of disease or harness the immune system to eliminate diseased cells in autoimmune diseases and cancer. The company states that its portfolio encompasses a range of modalities, each with the potential to be first- or best-in-class, and that it applies rigorous go/no-go criteria at each stage of development to advance only the most promising molecules.
Cullinan has also disclosed that it periodically refines its pipeline based on emerging clinical data. For example, it announced the discontinuation of the CLN-619 and CLN-617 programs after reviewing clinical data, and it notified the Massachusetts Institute of Technology of its decision to terminate a license agreement related to CLN-617, returning the licensed patent rights. At the same time, the company has emphasized a focused core pipeline centered on T cell engagers applied to well-validated targets in immunology and oncology.
Regulatory and clinical development environment
Cullinan’s programs operate within a regulatory framework that includes Fast Track and Breakthrough Therapy designations for certain assets. CLN-049’s Fast Track designation in relapsed/refractory AML is intended to facilitate development and expedite regulatory review of therapies that may address unmet medical needs. Zipalertinib’s Breakthrough Therapy Designation and rolling NDA process reflect a regulatory pathway that allows submission of application components as they are completed, subject to FDA agreement.
The company regularly reports clinical data from its trials at major scientific meetings, including the American Society of Hematology (ASH), the American Society of Clinical Oncology (ASCO), the European Society for Medical Oncology (ESMO), the American College of Rheumatology (ACR), and the World Conference on Lung Cancer (WCLC). These presentations cover efficacy signals, safety profiles, pharmacodynamic markers such as B cell depletion, and outcomes in genetically defined or high-risk patient subsets.
Financial and corporate context
In its SEC filings and press releases, Cullinan has reported maintaining substantial cash, cash equivalents, and investments, and has stated expectations that its cash resources provide runway into 2029 under its operating plans. The company also reports on research and development and general and administrative expenses, and it periodically updates investors on its financial results through quarterly earnings releases furnished on Form 8-K.
Cullinan’s board and management have experience in immunology and oncology clinical development, as reflected in the appointment of directors with backgrounds in biotechnology leadership and clinical research. The company also engages with the investment community through conference presentations, fireside chats, and dedicated investor events around key data readouts.
Business model and collaborations
