Descriptive Information

• Brief Title: Durvalumab With or Without Tremelimumab in Advanced Incurable Solid Malignancies Given With or Without Standard Chemotherapy Regimens
• Official Title: A Phase IB Study of Durvalumab (MEDI4736) With or Without Tremelimumab in Patients With Advanced Incurable Solid Malignancies Given With or Without Standard Chemotherapy Regimens
• Brief Summary: The purpose of this study is to find the highest dose of durvalumab or of durvalumab with tremelimumab that can be tolerated without causing very severe side effects when receiving standard chemotherapy and to see what effects the study drugs has on this type of cancer. Patients may receive durvalumab alone or in combination with tremelimumab.

Detailed Description

The researchers doing this study are also interested in looking for markers that will help predict which patients are most likely to be helped by the study drugs, durvalumab and tremelimumab. This is done by starting at a dose lower than the one that does not cause side effects in animals. Participants are given durvalumab alone or durvalumab together with tremelimumab and are watched very closely to see what side effects they have and to make sure the side effects are not severe. If the side effects are not severe, then new participants will be given a higher dose of durvalumab together with tremelimumab. Participants joining this study later on will get higher doses of durvalumab together with tremelimumab than participants who join earlier. This will continue until a dose is found that causes severe but temporary side effects. Doses higher than that will not be given.

The second purpose is to see if there are any differences in the side effects and the way durvalumab and tremelimumab are handled in your body when durvalumab is given together at the same time with tremelimumab compared to when durvalumab is given after tremelimumab. This is called dose level five.

Eligibility Criteria

Inclusion Criteria:

• Patients must have histologically and/or cytologically confirmed cancer that is advanced / metastatic / recurrent or unresectable and for which no curative therapy exists.

  • Patients must be considered suitable candidates for and eligible to receive one of the regimens (including durvalumab and tremelimumab alone (dose level 5) included in this protocol and which is open to accrual. For each regimen, specific criteria for registration may be applicable to the cohort/dose level to ensure tolerability in the planned phase II or III trials. Centres must confirm that the planned cohort is open to accrual and whether there are any restrictions on tumour types prior to approaching patients.
  • For etoposide/carboplatin regimen, patients must have untreated small cell lung cancer (SCLC).
  • If a formalin fixed paraffin embedded tissue block (from their primary or metastatic tumour) is available, patients must have provided informed consent for the release of the block. All patients must have provided informed consent for correlative studies.
  • Presence of clinically and/or radiologically documented disease. All radiology studies must be performed within 28 days prior to registration (within 35 days if negative). Patients ideally should have measurable disease.
  • Patients must have an ECOG performance status of 0, 1, or 2 (0 or 1 for untreated SCLC enrolled to etoposide/carboplatin). Patients with PS 2 must be considered fit for first line cytotoxic or immune based therapy and discussed with CCTG prior to enrolment.

Previous Therapy

• Cytotoxic Chemotherapy:

All Cohorts Except Etoposide-Carboplatin:

• Patients should not have received prior chemotherapy for advanced disease. Exceptions may be made for selected patients and regimens. Patients planned for dose level 5 may have received one line or prior chemotherapy. Consult CCTG before approaching patients.

Notes: Patients planned for cisplatin regimens should have received no more than 250mg mg/m2 prior to cisplatin.

Etoposide-Carboplatin Cohort:

• For dose levels 0-3, patients with untreated SCLC must have received two cycles of their first etoposide carboplatin regimen prior to registration to that chemotherapy cohort. For dose level 4, SCLC patients planned for the etoposide/carboplatin cohort may not have had prior chemotherapy regimens and do not have to have their first two cycles of etoposide-platinum prior to study entry.

Other Systemic Therapy:

• Patients may have received other prior therapies including immunotherapy, angiogenesis inhibitors, PARP inhibitors or signal transduction inhibitors. Patients who have received other treatment with PD-L1 / PD-1, CTLA4 or other antibodies must not have had intolerable toxicity or required steroids to manage toxicity.
• Patients must have recovered from all reversible toxicity related to prior chemotherapy or systemic therapy 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

Radiation:

• 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 registration. Exceptions may be made for low-dose, non-myelosuppressive radiotherapy after consultation with CCTG. Concurrent radiotherapy is not permitted. Patients planned for concurrent chemotherapy-radiation are not eligible. Patients with curative doses of radiation to marrow-bearing areas may not be eligible. Consult CCTG.

Surgery:

• Previous surgery is permitted provided that a minimum of 28 days (4 weeks) have elapsed between any major surgery and date of registration, and that wound healing has occurred.

• Patients must have recovered from any treatment related toxicities prior to registration (unless grade 1, irreversible, or considered by investigator as not clinically significant).
• Hematology:

Absolute neutrophils ≥ 1.5 x 10^9/L Platelets ≥ 100 x 10^9/L Hemoglobin ≥ 90 g/L

• Chemistry:

Bilirubin ≤ 1.5 x ULN (upper limit of normal) * If confirmed Gilbert's, eligible providing ≤ 3 x UNL; AST and ALT ≤ 2.5 x ULN (if liver metastases are present, ≤5 x UNL) Serum creatinine < 1.25 x ULN or: Creatinine clearance ≥ 50 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 registration in the trial and prior to tests which are considered to be study specific to document their willingness to participate.

Patients who cannot give informed consent (i.e. mentally incompetent patients, or those physically incapacitated such as comatose patients) are not to be recruited into the study. Patients competent but physically unable to sign the consent form may have the document signed by their nearest relative or legal guardian. Each patient will be provided with a full explanation of the study before consent is requested.

• Female patients of childbearing potential who are sexually active with a non sterilized male partner must use at least one highly effective method of contraception while on study and for 6 months after the last dose of durvalumab and tremelimumab or for 3 months after the last dose of durvalumab alone and consult product monograph for standard chemotherapy. Male partners of a female subject and non-sterilized male patients who are sexually active with a female partner of childbearing potential must use male condom plus spermicide while on study and for 6 months after the last dose of durvalumab and tremelimumab or for 3 months after the last dose of durvalumab alone and consult product monograph for standard chemotherapy. Female partners of a male subject must use a highly effective method of contraception throughout this period. Cessation of birth control after this point should be discussed with a responsible physician.
• Male patients should also refrain from donating sperm.
• 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. Investigators must assure themselves the patients registered on this trial will be available for complete documentation of the treatment, response assessment, adverse events, and follow-up.
• In accordance with CCTG policy, protocol treatment is to begin within 2 working days of patient registration

Exclusion Criteria:
