Cognitive Impairment in Patients Undergoing Cell- and Antibody-based Immunotherapies for Haematological Malignancies: The COGNITOX Study (COGNITOX)

22. april 2026 opdateret af: Aarhus University Hospital

Cell- and antibody-based therapies, including chimeric antigen receptor T-cell (CAR-T) therapy and bispecific antibodies, represent significant advances in the treatment of hematologic malignancies. These therapies optimise the patient's immune system to target and eliminate malignant cells, achieving profound and durable responses in patients where conventional treatment approaches have failed. However, their mechanism of action-through profound immune activation-introduces a challenging toxicity profile, including cytokine release syndrome and immune effector cell-induced neurotoxicity. Emerging evidence suggests that neurotoxicity associated with these therapies may extend beyond acute symptoms to include persistent cognitive impairments. Such impairments can manifest deficits in memory, attention, executive functioning, and processing speed, potentially compromising patients' quality of life, ability to manage daily activities and return to work.

The COGNITOX project explores the occurrence, clinical manifestations, and impact on quality of life of neuro-psychologically assessed and patient-reported cognitive impairment. The project's data set is generated through standardized neuropsychological tests (recommended by the International Cognition and Cancer) and validated patient reported outcome measures, to evaluate multiple cognitive domains. The project is developed in close collaboration between the Department of Haematology, Aarhus University Hospital and the Unit for Psychooncology and Health Psychology (EPoS), Department of Psychology and Behavioural Sciences, Aarhus University.

The current literature on cognitive impairment secondary to cell- and antibody-based therapies is limited, and none of the studies reported so far were conducted within a Danish healthcare context. Understanding the prevalence, severity, and functional impact of cognitive impairments in this patient population is critical. These insights will inform clinical practice, guide patient counseling, and support the development of targeted interventions aimed at mitigating cognitive decline. By generating robust data, this project seeks to improve the knowledge within the field and lay the foundation for an intervention study addressing the needs of patients undergoing these advanced immunotherapies.

The primary endpoint of the study is the occurrence, of cancer related cognitive impairment (CRCI) in patients treated with either chimeric antigen receptor T-cell therapy (CAR-T) or bispecific antibodies (BsAbs) as compared to high dose chemotherapy with autologous haematopoietic stem cell transplantation (AutoHSCT). Clinical manifestations and severity of CRCI will also be reported as descriptive co-primary endpoints.

Health related quality of life (HM-PRO score)
Tidsramme: 3 years

The HM-PRO has 24 items in Part A and 18 items in Part B. Each question has three response options:

Part A Not at all (score = 0) A little (1) A lot (2) Not applicable Part B Not at all (score = 0) Mild (1) Severe (2) The score range for Part A is 0-48 and for Part B is 0-36. The higher the total score, the greater the effect on a patient's quality of life.

The items in the HM-PRO are divided into four categories (domains):

Physical Behaviour (the first 7 items, maximum score of 14) Social Well-being (the second 3 items, maximum score of 6) Emotional Behaviour (the third 11 items, maximum score of 22) Eating and Drinking (the last 3 items, maximum score of 6)

HM-PRO Part A score is reported as a single total score HM-PRO A-total, score range 0-48

The HM-PRO Part A score is also reported as four separate scores:

HM-PRO Physical, score range 0-14 HM-PRO Social, score range 0-6 HM-PRO Emotional, score range 0-22 HM-PRO Eating/Drinking, score range 0-6 HM-PRO B-total (score range 0-36)
