Phase II trial evaluating to assess the feasibility and efficacy as first-line therapy for patients with non-resectable locally advanced HPV negative HNSCC of Durvalumab a PDL1-Inhibitor plus Tremelimumab a CTLA-4- Inhibitor in combination with radiotherapy and Durvalumab in combination with radiotherapy as first-line therapy.

2-arm, randomized, multicenter, phase II. Step 1 is Registration. All patients need to sign the informed consent form for registration. Tumor tissue then be send to the central lab for defining the HPV status. If the patient is HPV negative the site will be notified if they can further proceed to patient randomization.

Step 2 is Randomization of all eligible patients with a centrally diagnosed, HPV negative tumor in one of the two arms (Durvalumab plus Tremelimumab + radiotherapy; Durvalumab + radiotherapy) after signing the informed consent form for step 2.


The primary objective is to explore the feasibility and efficacy in terms of treatment discontinuation due to toxicity and in terms of 1-year progression free survival of a PDL1-Inhibitor plus a CTLA-4 Inhibitor in combination with radiotherapy and a PDL1-Inhibitor in combination with radiotherapy as first-line therapy for patients with non-resectable locally advanced HNSCC in the poor prognostic subgroup.

Secondary objectives are to investigate the benefit of the addition of a CTLA-4 Inhibitor and/or a PDL1-Inhibitor to radiotherapy in terms of overall progression free survival, overall survival and to investigate the approach in terms of safety, chronic toxicity and quality of life.

Condition Squamous Cell Carcinoma of the Head and Neck

Yes No Not Sure

Inclusion Criteria

Patients with locally advanced histopathologically confirmed HNSCC not candidate for primary surgical treatment
No distant metastasis (M0)
Tumor tissue available for central testing Patient with HPV/p16 negative disease (70% positively stained cells) as determined by central testing
Adequate normal organ and marrow function
Measurable tumor according to RECIST
Patients must be expected to complete the treatment
Age > 18 years at time of study entry
Female patients must either be of non-reproductive potential or must have a negative serum pregnancy test upon study entry and be willing to use adequate contraceptive measurements as described in the protocol
Non-sterilized males who are sexually active with a female partner of childbearing potential must be willing to use adequate contraceptive measurements as described in the protocol section 6.5.4

Exclusion Criteria

Participation in another clinical study with an investigational product during the last 3 months
Prior or current anticancer treatment to the head and neck area (e.g. radical attempted or tumor reductive surgery, neo-adjuvant chemotherapy, EGFR inhibitors or radiotherapy)
Any previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab or an anti-CTLA4, including tremelimumab
Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [eg, colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc]). The following are exceptions to this
Patients with vitiligo or alopecia
Patients with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement
Any chronic skin condition that does not require systemic therapy
Patients without active disease in the last 5 years may be included but only after consultation with the study physician
Patients with celiac disease controlled by diet alone History of primary immunodeficiency
History of allogeneic organ transplant
History of another primary malignancy except for
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
History of hypersensitivity to durvalumab and/or tremelimumab or any excipient
Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent
Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA
Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of patient safety or study results
Female patients who are pregnant or breastfeeding or male or female patients of reproductive potential who are not willing to employ effective birth control as described in the protocol from screening to 180 days after the last dose of durvalumab \+ tremelimumab combination therapy or 90 days after the last dose of durvalumab monotherapy, whichever is the longer time period
Distant metastasis
Patients who are institutionalised by official order
Mean QT interval corrected for heart rate (QTc) 470 ms calculated from 3 electrocardiograms (ECGs) using Fredericia's Correction
Receipt of live attenuated vaccination within 30 days prior to study entry step 2 or within 30 days of receiving durvalumab or tremelimumab
