Study to Assess the Efficacy and Safety of Nivolumab in Combination With Paclitaxel in Subjects With Head and Neck Cancer Unable for Cisplatin-based Chemotherapy (NIVOTAX)

• Status: Active, not recruiting
• Trial end date: 2026-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Chemotherapy for recurrent or metastatic head and neck squamous cell carcinoma is palliative and usually platinum based, and the patients often present with poor physical condition. Consequently, many of them are not able to withstand a platinum-based chemotherapy. The addition of taxanes to the armamentarium of drugs improve the outcome in this group of patients. An alternative and better tolerated regimen for these patients is paclitaxel in combination with cetuximab, included the in guidelines of the Spanish Society of Medical Oncology.

Recently, new treatments such as immune-checkpoint inhibitors have shown promising activity and good tolerability in patients with recurrent or metastatic head and neck squamous cell carcinoma and has been included in the recently published guidelines from the Society for Immunotherapy of Cancer. Nivolumab (anti-PD1) has been approved for patients progressing on or after platinum-based therapy, as it clearly impacts on overall survival.

This randomized phase II study will evaluate the efficacy of nivolumab plus paclitaxel for first-line treatment of recurrent or metastatic HNSCC in the platinum ineligible and platinum refractory settings. Control arm will be paclitaxel in combination with cetuximab, treatment included in the guidelines of the Spanish Society of Medical Oncology.

Inclusion Criteria:

1. Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care.

3. Patients not previously treated for recurrent/metastatic disease.

4. Radiographically measurable disease as defined by RECIST version 1.1. Previously irradiated lesions can only be considered as measurable disease if disease progression according to RECIST version 1.1.

5. Patients unable for cisplatin-based chemotherapy, defined "unable" by:

1. Karnofsky 70% or

2. Karnofsky 80-100% and amenable to chemotherapy, but:

i. Impaired renal function, creatinine clearance >30 mL/min and <80 mL/min GFR could be assessed by direct measurement (EDTA or creatinine clearance) if available or by calculation from serum or plasma creatinine (see annex 5), or

ii. grade ≥2 hearing loss, according to the NCI CTCAE v 5.0, or

iii. Class III heart failure according to the New York Heart Association (annex 9), or

iv. History of allergic reactions to cisplatin, carboplatin, or other platinum-containing compounds or

v. Prior dose of cisplatin ≥225 mg/m² for locally advanced disease (a patient who received prior RT + 3 cycles of cisplatin 100 mg/m2 or 3 cycles induction TPF (with cisplatin ≥75/m2) for locally advanced primary HN cancer can be included), or

vi. Disease progression or relapse during or within 6 months of receiving platinum-based therapy administered as neoadjuvant, adjuvant therapy or as concomitant chemotherapy with radiotherapy and have received at least 200 mg/m2 of cisplatin.

6. Male or female patients aged ≥18 years. Patients aged ≥70 years old can only be included with a G8 (Geriatric 8) health status screening score ≥ 14.

7. Clinical laboratory values as specified below within 28 days before the first dose of study drug:

1. Total bilirubin must be ≤2 × the upper limit of normal (ULN).

2. Magnesium ≥ lower limit of normal.

3. Calcium ≥ lower limit of normal.

4. ALT and AST must be ≤3 × ULN unless liver metastases are present, in which case they must be ≤5x ULN.

5. Hemoglobin must be ≥9 g/dL, absolute neutrophil count (ANC) must be ≥1.500/µL, WBC must be ≥2.000/µL and platelet count must be ≥100.000/µL.

8. Subjects who have received radiation as primary therapy are eligible if radiation therapy treatment was completed > 4 weeks prior to inclusion.

9. Documentation of PD-L1 status by IHC performed by the central lab at randomization. A pre-treatment tumor tissue sample should be sent. A newly obtained biopsy (within 6 months prior to start of study treatment) is preferred but an archival sample is acceptable, if several tumor samples are available, testing should be performed on the most recently obtained tumor sample.

10. Documentation of HPV p16 status (OPC) is required for HNSCC tumor of the oropharynx. For subjects with oropharyngeal cancer, sites are defined in annex 8. HPV status of tumor tissue has to be locally determined at screening by any of the following methods: p16 IHC, in situ hybridization, or polymerase chain reaction based assay. If HPV status by p16 IHC is positive result confirmation by PCR is mandatory.

Exclusion Criteria:

1. Male or female patients aged <18 years. Patients aged ≥ 70 years old should not be included with a G8 (Geriatric 8) health status screening score < 14.

1. Karnofsky 70%,

2. Impaired renal function, creatinine clearance >30 mL/min and <80 mL/min GFR could be assessed by direct measurement (EDTA or creatinine clearance) if available or by calculation from serum or plasma creatinine (see annex 5),

3. Class III heart failure according to the New York Heart Association (annex 9).
