Lymphocyte-Sparing And Radio-Immunotherapy in Head and Neck Carcinoma

Summary

The aim of this study is to investigate the effect of ATRA (Vesanoid) and the effect of tailored radiotherapy in patients with squamous cell carcinoma of the oropharynx, larynx or hypopharynx.

Conditions

• Oropharynx Cancer
• Larynx Cancer
• Hypopharynx Cancer
• Primary Head and Neck Tumor

Interventions

DRUG

Vesanoid

Before (chemo)radiotherapy: D1 to D3: 150mg/m2/day, 1 week before radiotherapy. Post (chemo)radiotherapy: D1 to D3: 150mg/m2/day every 3 weeks for up to 4 cycles post (chemo)radiotherapy

RADIATION

Standard radiotherapy

70 Gy in 35 fractions of 2 Gy over 6 (6 fractions per week) or hyperfractionated RT with a median therapeutic dose of 80.5 Gy delivered in 70 fractions of 1.15 Gy over 7 weeks.

RADIATION

Tailored radiotherapy

70 Gy in 35 fractions of 2 Gy over 6 weeks (6 fractions per week) or hyperfractionated RT with a median therapeutic dose of 80.5 Gy delivered in 70 fractions of 1.15 Gy over 7 weeks.

DRUG

Cisplatin

Cisplatin is recommended for the following patients : Stage T1-T2/N2a-N2b and T3/N0-N1-N2a-N2b. concomitant chemotherapy is standard of care treatments and should be administered as per standard practice. Chemotherapy will include one of the two cisplatin regimens specified in this protocol at the discretion of the participating centers. The centers must however treat all their recruited patients with one of the two regimens chosen before site activation. Chemotherapy should start the first day of radiotherapy. Cisplatin should be infused before radiation therapy delivery. The 2 options are: • Cisplatin 100 mg/m² i.v. on day 1 and 22 of radiotherapy (when 70 Gy are delivered in 6 weeks) or on day 1, 22 and 43 (when 70 Gy are delivered in 7 weeks). or • Cisplatin 40 mg/m² i.v. on day 1, 8, 15, 22, 29, 35 of radiotherapy (when 70 Gy are delivered in 6 weeks) or on day 1, 8, 15, 22, 29, 35, 42 of radiotherapy (when 70 Gy are delivered in 7 weeks).

DRUG

Cetuximab

Cetuximab is recommended for the following patients : Stage T1-T2/N2a-N2b and T3/N0-N1-N2a-N2b. concomitant Cetuximab is standard of care treatments and should be administered as per standard practice. Cetuximab therapy will be started with an intravenous loading dose of 400 mg/m2 one week before start of RT followed by six (radiotherapy over 6 weeks) or seven (radiotherapy over 7 weeks) weekly doses of 250 mg/m2.
