Head and Neck Squamous Cell Carcinoma: what the trials found

Several immunotherapies have been evaluated for Head and Neck Squamous Cell Carcinoma. Nivolumab demonstrated a statistically significant improvement in Overall Survival (OS) compared to the control group (p=0.0101) 11. Additionally, Pembrolizumab was evaluated across multiple trials; one study reported a 2-year Progression-free Survival (PFS) of 75.5% 3, and other studies confirmed its use in various cohorts [7, 20].

Lenvatinib showed significant improvements in Objective Response Rate (ORR) (p=0.0000019) 12 and Progression Free Survival (PFS) (p=0.0000037) 15 compared to standard treatments, although the difference in Overall Survival was not statistically significant in these trials [12, 15].

Cetuximab has been studied both as a monotherapy and in combination with radiotherapy; while it showed some efficacy, results for Progression-free Survival (p=0.8878) and Overall Survival (p=0.8175) did not reach statistical significance 13. A separate trial evaluating Cetuximab plus concomitant boost radiotherapy was also conducted [17, 18].

Alternative radiation modalities include stereotactic body radiotherapy 10, while the use of MEDI4736 in combination with Tremelimumab or as monotherapy did not show statistically significant differences in Overall Survival compared to standard of care in specific PD-L1 high subgroups 14.

Recent results — preliminary, needs further review

  • Pembrolizumab showed a median Overall Survival of 14.9 months and a progression-free survival rate of 12% vs 7% in a small cohort 19.
  • Atezolizumab was associated with a 50.0% Pathologic Complete Response (pCR) rate compared to 16.7% in a small study, with no Grade 3 or higher immune-related adverse events reported 21.
  • Cisplatin treatment resulted in adverse event rates ranging from 21.9% to 38.5% across various categories 5.
  • Intensity modulated radiation therapy (IMRT) was associated with specific quality of life scores across several functional subscales 6.
  • Other recent investigations include paclitaxel/carboplatin 1, IO102-IO103 in combination with pembrolizumab 4, Nivolumab+Relatlimab 8, L-NMMA 9, and IPI-549 22.

For the clinician treating this condition

  • Nivolumab is associated with a statistically significant improvement in Overall Survival compared to standard treatments.
  • Lenvatinib provides significant improvements in Objective Response Rate (ORR) and Progression Free Survival (PFS), though it did not significantly impact Overall Survival in the studied cohorts.
  • Atezolizumab showed a high rate of Pathologic Complete Response (pCR) in a small cohort without reported high-grade immune-related adverse events.
