iFIT is a trial for newly diagnosed transplant-ineligible patients with the bone marrow cancer myeloma. These patients are generally older and have a lower level of fitness than others. Patients can take part if their doctor would otherwise recommend the standard NHS treatment daratumumab, lenalidomide and dexamethasone (DRd). After six months of DRd, the subsequent treatment a patient receives in iFIT is based on two factors: the patient's fitness level and treatment response. The trial compares different treatment strategies to determine whether outcomes can be improved for specific patient groups.

iFIT2: Event-free survival (EFS)
The time from iFIT2 randomisation to the first of the following events: grade 4 haematological AEs, grade 3 and 4 non-haematological AEs (including SPMs), discontinuation of trial treatment, progression or death. Participants event-free at the time of analysis will be censored at their last date known to be alive and event-free.

Participants alive and for whom a second progression has not been observed at the time of analysis will be censored at their last known date to be alive and second progression-free.

Overall survival (OS)
The time from iFIT1/iFIT2/iFIT3 randomisation to death from any cause. Participants alive at the time of analysis will be censored at their last known date to be alive.
Time frame: From iFIT1/iFIT2/iFIT3 randomisation to OS event, assessed up to a maximum of 10.5 years post-randomisation.
Event-free survival (EFS; iFIT1 only)
The time from iFIT1 randomisation to the first of the following events: grade 4 haematological AEs (anaemia, neutropenia, thrombocytopenia), grade 3 and 4 non-haematological AEs (including SPMs), discontinuation of trial treatment, progression, or death. Participants event-free at the time of analysis will be censored at their last date known to be alive and event-free.
Time frame: From iFIT1 randomisation to EFS event, assessed up to a maximum of 6.5 years post-randomisation.
Survival after progression
The time from first documented evidence of disease progression to death from any cause. Participants alive at the time of analysis will be censored at their last known date to be alive. This endpoint is only defined for those who experience progression.
Time frame: From disease progression to death, assessed up to a maximum of 10.5 years post-randomisation.
Time to next treatment (TTNT)
The time from registration to the date of commencement of next treatment. Participants who do not receive next line treatment will be censored at the date of the last assessment or follow-up visit where they are known to have received no new therapy.

Overall response rate (ORR)
Overall response rate using the disease response category (sCR, CR, VGPR, PR, MR, SD, or PD).
