Combination of Durvalumab and Tremelimumab as Maintenance Treatment in Patients With Non Squamous and Squamous (NSCLC) (SOLUTION)

This is an interventional treatment trial for Squamous Non-small Cell Lung Cancer Read More

Inclusion Criteria:

• For inclusion in the study, patients should fulfill the following criteria

  • Histological diagnosis of NSCLC; for non-squamous NSCLC: no known sensitizing EGFR-mutation, no known EML4-ALK translocation. When a patient with non-squamous NSCLC has a KRAS mutation, further testing for EGFR and EML4-ALK is not necessary. For squamous NSCLC, EGFR and EML4-ALK testing is not necessary.
  • Availability of adequate in quality and quantity archived tumor material for IHC PD-L1 testing; (Preferably 15 but 8 mandatory slides or block of tumor tissue will be collected);
  • Stage IIIB or IIIC not eligible for radical treatment or stage IV according to TNM8 (Ref. 6);
  • Brain metastases should be treated with local therapy (stereotactic radiotherapy or whole brain radiotherapy), and patients should be asymptomatic, without treatment with steroids for four weeks before enrollment. Before enrollment, new brain imaging (contrast-CT or gadolinium-MRI) is needed to demonstrate that there is no progression in the brain when the last brain imaging is more than four weeks earlier. Screening for brain metastases is not necessary in patients that were previously not diagnosed with brain metastases and that are without signs indicative of brain metastases.
  • ≥ 18 years of age at time of study entry;
  • WHO performance status 0 or 1; at enrollment
  • Body weight > 30 kg at enrollment
  • Evaluable disease with CT or MRI according to RECIST 1.1 (except for patients with a CR after 4 cycles of platinum-based doublet chemotherapy, these patients are also eligible);
  • Stable disease or response by RECIST criteria response after 4 cycles of platinum-based doublet chemotherapy;
  • Adequate normal organ and marrow function:
  • Absolute neutrophil count (ANC) ≥ 1.5 x 109/L (> 1500 per mm3)
  • Platelet count ≥ 100 x 109/L (>100,000 per mm3)
  • Serum bilirubin ≤ 1.5 x institutional upper limit of normal (ULN). This will not apply to subjects with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology)AST (SGOT)/ALT (SGPT) ≤ 2.5 x institutional upper limit of normal; for patients with liver metastases ≤ 5 x institutional upper limit of normal
  • Measured or calculated creatinine clearance ≥45 mL/min by the Cockcroft-Gault formula (Appendix E)
  • Haemoglobin ≥ 9.0 g/dL
  • Patient with following autoimmune or inflammatory disorders are eligible:
  • Vitiligo or alopecia
  • Hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement
  • Any chronic skin condition that does not require systemic therapy
  • Active disease in the last 5 years may be included but only after consultation with the study investigator
  • Celiac disease controlled by diet alone
  • Patient with history of another primary malignancy are eligible in the following cases:
  • Malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of IP and of low potential risk for recurrence
  • Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
  • Adequately treated carcinoma in situ without evidence of disease
  • Women of child bearing potential (WOCBP) must have a negative serum pregnancy test within 72 hours prior to the first dose of study treatment.

Note: women of childbearing potential are defined as premenopausal females capable of becoming pregnant (i.e. females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low body weight, ovarian suppression or other reasons.

• Patients of childbearing / reproductive potential should use adequate birth control measures, as defined by the investigator, during the study treatment period and from screening to 90 days after the last dose of durvalumab monotherapy or 180 days after the last dose of durvalumab + tremelimumab combination. A highly effective method of birth control is defined as a method which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Such methods include:
• Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal)
• Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable)
• Intrauterine device (IUD)
• Intrauterine hormone-releasing system (IUS)
• Bilateral tubal occlusion
• Vasectomized partner
• Sexual abstinence (the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient)
• Female subjects who are breast feeding should discontinue nursing prior to the first dose of study treatment, from screening to 90 days after the last dose of durvalumab monotherapy or 180 days after the last dose of durvalumab + tremelimumab combination therapy or pemetrexed.
• Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up;
• Before patient registration, written informed consent must be given according to ICH/GCP, and national/local regulations.

Exclusion Criteria:

• Patients should not enter the study if any of the following exclusion criteria is fulfilled

  • Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or the follow-up period of an interventional study
  • Mixed small-cell lung cancer and NSCLC histology, sarcomatoid variant or large cell neuro-endocrine variant
  • Patients with known history of leptomeningeal carcinomatosis
  • Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria
