Brief Summary

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

I238A: The purpose of this study is to find out what effects being treated with durvalumab has on cancer. The researchers doing this study also want to evaluate if prednisone (a type of steroid), when given together with durvalumab, can reduce any side effects.

I238B: The purpose of this study is to allow patients previously enrolled on a completed CCTG trial to continue treatment with durvalumab (+/- tremelimumab)

Detailed Description

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

Durvalumab is a new type of drug for many types of cancer. Durvalumab is an immunotherapy drug and not a chemotherapy drug. Laboratory tests show that it works by allowing the immune system (PD-1 and PD-L1 interaction) to detect your cancer and reactivating the immune response. This may help to slow down the growth of cancer or may cause cancer cells to die. Durvalumab has been shown to shrink tumours in animals and has been studied in more than 6000 people. This drug seems promising but it is not clear if it can offer better results than standard treatment alone or if people can be re-treated with durvalumab after previous side effects

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients must have histologically and/or cytologically confirmed solid tumour, that is advanced/ metastatic/recurrent or unresectable and for which no curative therapy exists.
* Patients must live within Canada and have received durvalumab alone, or durvalumab in combination with tremelimumab, with or without chemotherapy/targeted therapy. Patients who have received other anti PD-1/PD-L1 agents +/- anti CTLA agents are eligible, providing full details of prior therapy, toxicity and management are available. Consult with CCTG for further details.
* Patients must have previously discontinued immunotherapy due to an irAE.
* Immune-related adverse events must have resolved to ≤ grade 1 or baseline and patient must have completed corticosteroid therapy at least 28 days prior to registration in this current study.
* Complete response, partial response or prolonged stable disease (SD ≥ 8 weeks) to initial immunotherapy. Patients that received prior adjuvant/neoadjuvant/consolidation immunotherapy are eligible providing there has been at least a 6 month treatment free interval prior to enrollment and patient has received at least one standard-of-care chemotherapy regimen in the palliative setting (discuss with CCTG if chemotherapy is not considered standard of care or not indicated or patient refused/not eligible as such patients are eligible).
* Patients must have a life expectancy of at least 12 weeks.
* Tumour material may have already been submitted to CCTG for the initial trial. If an additional formalin fixed paraffin embedded tissue block (from their primary or metastatic tumour) is available from tissue collected after immunotherapy discontinuation, patients must have provided informed consent for the release of the block. All patients must have provided informed consent for correlative studies. If patients from non-CCTG trials or commercial use are eventually enrolled, tumour material is also required if available, preferably from tissue collected after immunotherapy discontinuation.
* Presence of clinically and/or radiologically documented disease. All radiology studies must be performed within 28 days prior to enrollment (within 35 days if negative). Patients ideally should have measurable disease.
* ECOG performance status 0 or 1
* Previous Therapy
* Patients who received other relevant standard cancer therapies since discontinuing immunotherapy remain eligible for inclusion as follows:

* Patients may have received prior cytotoxic chemotherapy following discontinuation of immunotherapy for irAE.
* Patients may have received other prior therapies such as tyrosine kinase inhibitors or other targeted agents, following discontinuation of immunotherapy for irAE.
* Patients may not have received subsequent immune checkpoint inhibitors (anti-PD-(L)1 and anti-CTLA-4) following discontinuation of immunotherapy for irAE. Vaccines and oncolytic viruses are permitted.
* Patients must have recovered from all reversible toxicity related to prior chemotherapy or systemic therapy (unless grade 1, irreversible, or considered by investigator as not clinically significant) and have adequate washout as follows: Longest of one of the following:

* Two weeks;
* 5 half-lives for investigational agents;
* Standard cycle length of standard therapies.
* Prior external beam radiation is permitted provided a minimum of 28 days (4 weeks) have elapsed between the last dose of radiation and date of enrollment. Exceptions may be made for low-dose, non-myelosuppressive radiotherapy after consultation with CCTG. Concurrent radiotherapy is not permitted.
* Previous surgery is permitted provided that a minimum of 28 days (4 weeks) have elapsed between any major surgery and date of enrollment, and that wound healing has occurred.
* Absolute neutrophils ≥ 1.5 x 10\^9/L
* Platelets ≥ 100 x 10\^9/L
* Hemoglobin ≥ 90 g/L
* Bilirubin ≤ 1.5 x ULN (upper limit of normal)
* AST and ALT ≤ 2.5 x ULN - ≤ 5.0 x ULN (if patient has liver metastases)
* Serum creatinine \< 1.25 x ULN or
* Creatinine clearance ≥ 40 mL/min
* Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate.
* Patients must be accessible for treatment and follow up. Patients registered on this trial must be treated and followed at the participating centre. This implies there must be reasonable geographical limits (for example: 1 ½ hour's driving distance) placed on patients being considered for this trial.
* In accordance with CCTG policy, protocol treatment is to begin within 2 working days of patient enrollment
* Women/men of childbearing potential must have agreed to use a highly effective contraceptive method
* Subjects should not donate blood while participating in this study, or for at least 90 days following the last infusion of durvalumab


* Patients must be currently enrolled and receiving active treatment on a treatment arm containing durvalumab +/- tremelimumab with or without maintenance pemetrexed with no contraindications to continue receiving their current study regimen according to the protocol to which the patient is currently enrolled.
* For BR.34 ONLY: patients who have disease progression (iUPD) on durvalumab may receive one dose of tremelimumab (75 mg) along with their next durvalumab infusion as long as all the following criteria are met:

* Patient is clinically stable
* According to the judgement of the treating physician, the patient had clinical benefit while receiving tremelimumab in the induction phase on BR.34
* ECOG performance status of 0 or 1
* Laboratory values meet the criteria below:

Absolute neutrophils ≥ 1.5 x 10\^9/L Platelets ≥ 100 x 10\^9/L Hemoglobin ≥ 90 g/L Bilirubin ≤ 1.5 x ULN (upper limit of normal)\* AST and ALT ≤ 2.5 x ULN (if liver metastases are present, ≤ 5.0 x ULN) Serum creatinine \< 1.25 x ULN or Creatinine clearance ≥ 45 mL/min

Exclusion Criteria
