Study summary

This study will evaluate the long-term safety and efficacy of CRISPR CAR T cellular therapies

Read the detailed description

All subjects with hematological and solid malignancies who are enrolled in a parent study and were exposed to allogeneic CRISPR CAR T cellular therapy will be asked to participate in this long-term follow-up (LTFU) study. Subjects who have completed the parent study for the protocol-defined duration, or who have discontinued the parent study early, or who are in secondary follow-up (follow up of subjects with progressive disease or who receive a subsequent line of anticancer therapy) in the parent study may enroll in this LTFU study. This will allow for collection of long-term efficacy data (as applicable) and safety data up to 15 years post-treatment with CRISPR CAR T cellular therapies.

Inclusion criteria

  • Able to understand and comply with protocol-required study procedures and voluntarily sign and date a written document.
  • Must have received CRISPR CAR T cellular therapy.

Exclusion criteria

Exclusion Criteria:

  • There are no specific exclusion criteria.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. The incidence of adverse events, serious adverse events and adverse events of special interest related to CRISPR CAR T cellular therapy treatment.

    The number and percentage of subjects with CRISPR CAR T cellular therapy related SAEs and AESIs will be summarized.

    Time frame: 15 years

Secondary outcomes

  1. The overall survival and duration of remission/response following CRISPR CAR T cellular therapy treatment

    Overall survival will be calculated as the time between the initial dose of CRISPR CAR T cellular therapy in the parent study and death due to any cause. Duration of remission/response will be calculated as the time between the first objective response to first disease progression or death due to any cause.

    Time frame: 15 years
