Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RADAR is a multicentre, international, randomised, open-label phase III clinical trial composed of 2 trials running in parallel. Trial 1 will be led and sponsored by University College London (UCL) and conducted in Europe and Australia/New Zealand. Trial 2 will be led by the Canadian Cancer Trials Group (CCTG) and conducted in North America, with CCTG the regulatory sponsor in Canada, and University of Miami the regulatory sponsor and IND holder in the US. Datasets from Trial 1 and Trial 2 will be combined to achieve the total sample size. Data analysis will be performed by UCL and therefore UCL is responsible for the clinicaltrials.gov entry.

Eligible patients will be randomised to receive either ABVD or A2VD chemotherapy.

An interim PET-CT scan will be performed after 2 cycles of treatment, which will be used to adapt subsequent treatment. Patients will receive a total of 3-4 cycles of chemotherapy and may also receive involved site radiotherapy as consolidation.

Patients will be followed up for a minimum of 5 years after treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Eligible patients will be randomised to receive either ABVD chemotherapy (doxorubicin, bleomycin, vinblastine and dacarbazine) or A2VD chemotherapy (doxorubicin, brentuximab vedotin, vinblastine and dacarbazine, with growth factor support).

If patients agree, they will have a PET-CT scan after 1 cycle (PET1). The result of this scan will be blinded and used for exploratory endpoints only. Treatment will not be influenced by the result of this scan.

All patients will have a PET-CT scan after 2 cycles of treatment (PET2) which will be centrally reviewed. The Deauville score from central review will be used to risk adapt subsequent therapy as follows:

* Patients with Deauville score 1-3 will have one further cycle of their randomised chemotherapy and then enter follow up.
* Patients with Deauville score 4 will have two further cycles of their randomised chemotherapy followed by involved site radiotherapy
* Patients with Deauville score 5 will be withdrawn from trial treatment. They will have further treatment at their treating clinician's discretion and will enter follow up for the trial.

Patients with Deauville score 4 on PET2 will have a final PET-CT scan to confirm adequate treatment response.

Patients will be followed up for a minimum of 5 years after completing treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ABVD +/- ISRT

2 x 28 day cycles of ABVD: Doxorubicin 25mg/m\^2 IV days 1 \& 15 Bleomycin 10000 IU/m\^2 days 1 \& 15 Vinblastine 6mg/m\^2 days 1 \& 15 Dacarbazine 375mg/m\^2 days 1 \& 15

PET-CT after 2 cycles will determine subsequent treatment:

Deauville score 1-3 (PET CMR): 1 further cycle of ABVD then follow up Deauville score 4 (PET positive): 2 further cycles of ABVD followed by involved site radiotherapy (ISRT) Deauville score 5: withdraw from trial treatment; further treatment will be given at the treating clinician's discretion. Enter follow up for the trial.

* Creatinine clearance (measured or calculated \>40ml/min
* Total bilirubin \<1.5 x upper limit of normal, unless attributable to disease or known Gilbert's syndrome
* ALT or AST \< 2 x upper limit of normal
