This phase II/III trial studies the best approach in improving quality of life and survival after a donor stem cell transplant in older, weak, or frail patients with blood diseases. Patients who have undergone a transplant often experience increases in disease and death. One approach, supportive and palliative care (SPC), focuses on relieving symptoms of stress from serious illness and care through physical, cultural, psychological, social, spiritual, and ethical aspects. While a second approach, clinical management of comorbidities (CMC) focuses on managing multiple diseases, other than cancer, such as heart or lung diseases through physical exercise, strength training, stress reduction, medication management, dietary recommendations, and education. Giving SPC, CMC, or a combination of both may work better in improving quality of life and survival after a donor stem cell transplant compared to standard of care in patients with blood diseases.

The goal of this clinical study is to learn more about the long-term safety, effectiveness
and prolonged action of Kite study drugs, axicabtagene ciloleucel, brexucabtagene autoleucel,
KITE-222, KITE-363, KITE-439, KITE-585, and KITE-718, in participants of Kite-sponsored
interventional studies.

The primary purpose of the Research Database is to have a comprehensive source of
observational data that can be used to study HSC transplantation and cellular therapies.

A secondary purpose of the Research Database is to have a comprehensive source of data to
study marrow toxic injuries.

Objectives:

To learn more about what makes stem cell transplants and cellular therapies work well such
as:

- Determine how well recipients recover from their transplants or cellular therapy;

- Determine how recovery after a transplant or cellular therapy can be improved;

- Determine how a donor's or recipient's genetics impact recipient recovery after a
transplant or cellular therapy;

- Determine how access to transplant or cellular therapy for different groups of patients
can be improved;

- Determine how well donors recover from the collection procedures.
