As with many types of cancer, immunotherapy is changing the management of squamous cell carcinoma of the head and neck (HNSCC). In a locally advanced or metastatic setting, treatment options have long been curtailed, but this paradigm is currently changing. Checkpoint inhibitors were the first to be validated in second-line treatment with PD-1 and PD-L1 inhibitors and these treatments are available in USA for first-line use. In addition, many studies are underway to use its molecules earlier in the care or try to increase their effectiveness with associations. The issues of patient selection that would benefit the most from immunotherapy and the evaluation of the response to these treatments are not completely solved. The goal is here to update the possibilities of current treatment by immunotherapy in HNSCC as well as on various development pathways in progress.


Head and neck squamous cell carcinoma, checkpoint inhibitors, immunotherapy, clinical trial


Head and neck cancers are currently responsible for more than 700,000 cases and more than 350,000 deaths per year[1]. After a heavy treatment combining surgery, radiotherapy and chemotherapy, more than half of the patients relapse locoregional or metastatic[2]. With chemotherapy and anti-epidermal growth factor receptor, advanced treatment was relatively limited before the arrival of immunotherapy in the therapeutic arsenal. Head and neck cancers are cancers inducing immunosuppression and therefore particularly likely to respond well to immunotherapy. The purpose of this article is to review studies validating the use of first-line and second-line checkpoint inhibitors (CPIs) in HNSCC, as well as studies evaluating new indications. The aim is also to evaluate the new immunotherapy modalities under evaluation and to discuss the difficulties of using these new treatment.

Validated treatment in second line

Nivolumab was the first molecule to be approved by the Food and Drug Administration with the Checkmate 141. This showed an overall survival improvement of 7.7 months vs. 5.1 months (HR = 0.68, 95%CI: 0.54-0.86) compared with monotherapy with docetaxel, methotrexate or cetuximab in HNSCC progressing after a first platinum-based line. This difference was greater in PD-L1 patients > 1% with an OS of 8.2 months vs. 4.7 months, but the curves were also separated for PD-L1 negative patients (< 1%). Nivolumab was therefore approved regardless of PD-L1 expression[3].

Pembrolizumab was studied in the same situation with the Keynote 0-40 Phase III study, but this time docetaxel was given every 3 weeks at a dose of 75 mg/m2. While the first analysis was not significant, the discount reached statistical significance with a median overall median survival of 8.4 months (95%CI: 6.4-9.4) vs. 6.9 months (95%CI: 5.9-8.0), HR = 0.80 (95%CI: 0.65-0.98, P = 0.0161). The reduction in HR relative to nivolumab can be explained by several factors. First, a cross-over effect in the chemotherapy group with many patients receiving immunotherapy secondarily, secondly because a majority of patients received docetaxel, which is the most effective chemotherapy and also by the use of docetaxel every three weeks used in this study which is probably more effective than the weekly rhythm used with nivolumab. In the subgroup analyzes, survival was significantly increased from 7.9 to 11.6 months in favor of pembrolizumab in patients with PD-L1 > 50%. There was no difference in the PD-L1 population < 50%. These results led to the approval in Europe of pembrolizumab in PD-L1 patients > 50%[4].

A third phase 3 trial, the EAGLE study, compared an anti-PD-L1 (durvalumab) alone or with an anti-CTLA4 (Tremelimumab) to a standard chemotherapy. This study was negative for the overall survival, but the durvalumab arm as monotherapy was consistent with nivolumab and pembrolizumab with a median overall survival at 7.6 months and a response rate of 17.9%. In addition, the control arm was superior to what was expected because weekly paclitaxel was predominantly used (which is probably the best treatment option for these patients) and there was an important crossover with control arm patients receiving immunotherapy[5].

First line treatment

The Keynote 048 trial is an open-label, randomized, phase 3 trial comparing 887 patients in first line with pembrolizumab to the extreme protocol [cisplatin or carboplatin, 5-fluorouracile (5FU) and cetuximab][6]. Pembrolizumab was administered at a fixed dose of 200 mg every 3 weeks alone or in combination with cisplatin and 5FU chemotherapy. The stratification factors were the expression of PD-L1 by tumor proportion score (TPS: expression of PD-L1 by tumor cells ≥ 50% vs. < 50%), p16 status for oropharyngeal tumors (positive vs. negative) and Eastern Cooperative Oncology Group status (0 vs. 1). Pembrolizumab showed a benefit in overall survival over chemotherapy and cetuximab in the combined positive score (CPS) population ≥ 20 (a score that studies expression on both tumor cells and immune cells in the microenvironment) with a median of 14, 8 months vs. 11 months; HR 0.58 (95%CI: 0.44-0.78). This advantage was found in the group of CPS ≥ 1 with a median of 12.3 months vs. 10.4 months; HR 0.74 (95%CI: 0.61-0.90). But it is important to note that if survival is better with pembrolizumab, at the beginning immunotherapy is deleterious for some patients with more deaths in the first six months. In terms of tolerance, treatment-related adverse event levels of Gr 3-5 were 17% with pembrolizumab against 69% with the Extreme protocol. The update during the American Society of Clinical Oncology (ASCO) 2019 also showed a benefit in overall survival in the pembrolizumab group associated with chemotherapy compared with the Extreme group, regardless of the subgroup of patients. The median OS was 14.7 months vs. 11 months, respectively; HR 0.60 (95%CI: 0.45-0.82) for the CPS group ≥ 20, 13.6 months vs. 10.4 months; HR 0.65 (95%CI: 0.53-0.80) for the CPS group ≥ 1 and 13 vs. 10.7; HR 0.72 (95%CI: 0.60-0.87) months in total population.

It is therefore the first randomized trial that demonstrates an improvement in overall survival compared to standard platinum and cetuximab treatment in the first line. This trial also establishes the CPS as a valid marker for selecting patients most likely to benefit from pembrolizumab monotherapy. In CPS ≥ 20, the toxicity profile favors treatment with pembrolizumab monotherapy, whereas the combination of pembrolizumab with chemotherapy seems the best alternative for CPS < 20 that can benefit. Pembrolizumab in monotherapy may also be discussed in slowly progressive patients with CPS < 20. Be that as it may, it is likely that this study will upset the frontline management of HNSCC cancers in the front line.

There are currently two other studies currently underway evaluating first-line CPIs. Durvalumab alone or in combination with tremelimumab is compared to the EXTREME protocol in the KETREL trial and the nivolumab and ipilimumab combination is still compared to the same protocol in the CA609-651 trial.

Finally, these new studies will change the management of HNSCC cancers. We propose in Figure 1 a decisional tree for the treatment of recurrent or metastatic HNSCC.

Immunotherapy more precocious

Because of the improvement in overall survival provided by the inhibitors of chekpoint, the question arises of introducing these treatments earlier in curative intent for localized disease, in neoadjuvant or adjuvant treatment.

In adjuvant, trials are in progress with comparative immunotherapies or added to cisplatin or cetuximab during radiotherapy, but there is currently no efficacy data. There is no sign of toxicity so we expect a better tolerance than current treatments. A randomized Phase II trial compared potentiated radiotherapy with cetuximab or pembrolizumab in inoperable patients not eligible for cisplatin. Tolerance was better in the pembrolizumab group with a 3-4 grade toxicity of 69% vs. 88% with cetuximab. There was particularly less mucositis and radiodermatitis with pembrolizumab[7].

In neoadjuvant, a phase I is in progress that combines durvalumab with TPF (cisplatin docetaxel 5FU) to potentiate induction chemotherapy.

A phase 2 study also studied still in neoadjuvant 23 patients with high-risk HNSCC cancer (probable R1 resection or capsular rupture) who received pembrolizumab 1 to 3 weeks before surgery. There was 47% response with an anti-tumor effect on more than 10% of the surface, including 32% major response on more than 70% of the surface and 1 complete response[8]. Similar results have been observed with nivolumab[9].

It is also possible that immunotherapy may make subsequent chemotherapy more effective, which would favor earlier administration of immunotherapy.

News immunotherapy

Many immunotherapy molecules with different mechanisms of action are currently under development. A review of the 2016 literature presented the latest insights into the field of immunotherapy for HNSCC[10]. Many immunotherapy associations were already being tested. The goal here is to present some of these innovations with a promising future to show the diversity of this one. Table 1 summarizes the molecules presented.

Danvatirsen with durvalumab Inhibitory antisense oligonucleotide of STAT3 + anti-PD-L1 Phase Ib/II Metastatic HNSCC naive of anti-PD-L1

Dendritic cell vaccination with conventional chemotherapy Mature CD loaded with WT1 peptides + OK-432 (TLR-4 ligand) Phase I/II Recurrent/metastatic HNSCC

A phase 1 study showed promising results with a bispecific anti-PD-L1 and anti-transforming growth factor-β (TGF-β) antibody (M7824). The goal is to inhibit TGF-β, which increases tumor immunodepression. In addition, inhibition of the TGF-β pathway could increase the activity of anti-PD-L1. Among 32 patients, 7 had partial response, 6 had tumor stability, and grade III was found among 10 patients (31.3%). Further development will be interesting to follow[11].

Monalizumab is a new CPI targeting NKG2A. This is expressed on CD8+ lymphocytes and on NK lymphocytes. The ligand of NKG2A, human leucocyte antigens (HLA)-E, is overexpressed in HNSCC. Blocking this interaction stimulate CD8+ and NK lymphocytes and increase antibody-dependent cell-mediated cytotoxicity (ADCC). Since Cetuximab acts mainly via an ADCC mechanism, it could be potentiated by Monalizumab. A phase II study included 40 patients to receive weekly cetuximab combined to monalizumab every two weeks after failur of platin. The response rate, which was the primary endpoint, was 27.8%, or 11 out of 40 patients (compared to 13% with cetuximab alone according to historical data). The tolerance was particularly good, making this association a promising issue[12]. It is interesting to note that monalizumab seems to be effective after failure of an anti-PD-1.

Another phase Ib/II study investigated the combination of danvatirsen with durvalumab among patients with metastatic HNSCC naive of anti-PD-L1. Danvatirsen is an inhibitory antisense oligonucleotide of STAT3 (that stimulates the immunosuppressive function of the microenvironment). Among 44 treated patients, 23% of responses (higher than those found with durvalumab monotherapy) were found with 3 complete responses. An increase of transaminases and transient thrombocytopenia were the major toxicities and it seems there is no additive toxicity of the two treatments[13].

SD101 is a TLR9 agonist stimulating the activity of dendritic cells. This later became antigen-presenting cells to activate an anti-tumor response via T lymphocytes. A phase I/II study investigated the combination with pembrolizumab. Patients received pembrolizumab every 3 weeks and SD-101 injected into a single tumor site each week for 4 injections and then every 3 weeks up to 7 injections. Among the 26 patients included, the median injections of SD-101 administered were 5. Patients experienced injection site reactions and influenza-like illness with 28% of toxicities ≥ grade 3. The immune-induced effects of pembrolizumab do not appear to have increased. The response rate in mITT (that is to say, among the 23 patients who had reached at least the first tumor evaluation) was 30.4% with 7 partial responses, 3 stabilities, 10 progressions in imaging and 3 clinical progressions before the scan. Tumor size reductions ≥ 30% were observed in injected lesions (8/18 or 44.4%) as well as in non-injected lesions (8/14 or 57.1%). At the time of the analysis, 5 of the 7 responses were ongoing (1 to 27 weeks). Therefore, stimulation of dendritic cells seems promising with activity in the injected site, but also at a distance, at the cost however of a significant toxicity[14].

Epacadostat is an oral IDO1 inhibitor (indoleamine 2,3-dioxygenase) showing good phase I and II in combination with pembrolizumab[15]. IDO1 is an enzyme expressed in the tumor microenvironment that has an immunosuppressive effect by decreasing tumor infiltration by cytotoxic T lymphocytes (TILs). But in the face of phase III failures in melanoma, development has unfortunately been halted[15].

Associations with tyrosine kinase inhibitors (TKIs) have also been studied in a phase Ib/II study. Lenvatinib, a broad-spectrum TKI, has been associated with pembrolizumab in 22 progressive metastatic patients after at least one line of chemotherapy. The 24-week response rate was 36% with a median response time of 8.2 months, a progression-free survival (PFS) of 8.2 months, and one year progression-free survival rate of 37%. But the toxicity is important with 91% of side effect, of which 14% of grade 4 and 18% of patients who had to stop the treatment. The main symptoms were fatigue, loss of appetite, hypertension and digestive disorders. Associations with other less toxic tyrosine kinase inhibitors may be considered[16].

Another trial associated durvalumab with an activating agonist of the immune response, MEDI6974 (Ox40 agonist antibody). The treatments were administered for a short time before surgery. An increase and activation of cytotoxic lymphocytes within the tumor has been demonstrated. This association could potentially be interesting[17].

A phase I/II study investigated dendritic cell vaccination with conventional chemotherapy in patients with head and neck cancer[18]. Eleven patients with relapsed or refractory disease were recruited (with HLA-A2 or HLA-A24 positive as well as WT1 expression, a tumor antigen). Mature dendritic cell (DC) loaded with WT1 peptides were injected intradermally approximately every 2-3 weeks. OK-432 (TLR-4 ligand) was administered subcutaneously near the vaccination sites to activate the DCs. Treatment was generally well tolerated with none of the patients with grade 2 adverse events except for hematologic adverse events with leucocytopenia and grade 2 anemia. Non-hematologic adverse events were consistent with the classic adverse effects of chemotherapy (discomfort, nausea, anorexia, and constipation except transient erythema at injection sites and low-grade fever). 5 patients presented a stabilization of the disease and 6 patients a progression of the disease. The median PFS and OS were 6.4 months and 12.1 months, respectively. But the median duration of PFS and OS of patients with stable disease was significantly longer than that of patients with progressive disease. The median PFS was 13.0 months vs. 2.8 months (P = 0.00136) and the median OS was 30.3 months vs. 8.1 months (P = 0.0126). Two patients had a long-term survival of 30.3 m and 44.4 m. Furthermore, all patients with stable disease showed improvement of WT1-specific immune responses after vaccination in all tests performed [HLA tetramer, interferon gamma (IFNγ) ELISPOT and mobilization CD107a] as well as an increased Th1/Th2 ratio of 1.36 times on average. Dendritic cell vaccination is therefore an interesting research path because of its efficacy in some patients and its good tolerance[18].

In conclusion, many promising new immunotherapies are being developed with different mechanism of action. Some may be used alone and other combined with CPIs or other conventional therapy.

Difficulty of assessing immunotherapy

Evaluation of immunotherapies may be different and more difficult than conventional anti-tumor treatments. In fact, patients treated with CPI observed phenomena of pseudo-progression (tumor response after an initial progression) and, on the contrary, hyperprogression phenomena with a rapid and significant increase in tumor volume.

These pseudo progression are probably due to infiltration of immune and inflammatory cells and/or a delayed clinical response. These phenomena are relatively rare but may explain the benefit of immunotherapy treatment beyond progression. For example, in the Checkmate 141 study, of 240 patients randomized to receive nivolumab, 146 showed progression according to RECIST. Sixty-two of these patients continued nivolumab and 84 discontinued treatment. Of the 60 patients who continued nivolumab evaluable for the response, 15 (25%) had not changed their tumor burden and 15 (25%) had a reduction in the size of the target lesion (3% of patients had responded by RECIST after progression). This attests the interest to continue the treatment beyond the progression if the general state remains correct and in the absence of rapid progression. Note that the expression of PDL1 does not seem to differentiate patients who will be treated or not beyond progression[19].

This pseudo progression can in part explain the possible increase of efficacy of subsequent chemotherapy after failure of anti-PD-1. Indeed a French retrospective study in 82 patients receiving chemotherapy (45% monotherapy and 55% combination therapy) after failure of immunotherapy showed a 30% responses and a 57% disease control, higher than those usually observed in the 3rd line. Chemotherapy could also activate the immune system by releasing tumor antigens, with check point inhibitors known to remain in the body for a long time.

Hyperprogressions are associated with poorer survival. A French retrospective study suggested that hyperprogression can be observed in 29% of patients treated by immunotherapy[20]. This controversial phenomenon could be induced by an excessive immune reaction, a paradoxical action of anti-PD-1/PD-L1 promoting tumor development, or ultimately only the natural history of advanced phase cancer.

Finally, unlike conventional chemotherapy, the occurrence of autoimmune adverse events seems to correlate with the effectiveness of the CPIs. In an analysis of 114 patients treated with anti-PD-1: 43% exhibited immunological toxicity. These patients had higher response rates (30.6% vs. 12.3%), better progression-free survival (6.9 months vs. 2.1 months) and improved overall survival (12.5 months vs. 6.8 months). This analysis may of course be biased since patients who benefit from immunotherapy pursue it longer and are therefore more likely to develop immunological toxicity[21].

Predictive factor of efficacy of immunotherapy

One of the major challenges of immunotherapy is to select patients responding to immunotherapies with predictive biomarkers of effectiveness. Currently, the only one used is the expression of PDL1 but it is very imperfect, especially with excellent results in PDL1 negative patients.

The expression of PD-L2 and the signature IFNγ have been explored, but do not seem particularly convincing.

HNSCC have been classified into 6 groups: immunoreactive, inflammatory, Human Papilloma Virus (HPV)-like, classical, hypoxemic and mesenchymal[22]. The inflammatory and immunoreactive profiles are probably more sensitive to immunotherapies because they are strongly infiltrated by cells of the immune system. The important tumoral infiltration by the CD8 lymphocytes could characterize this inflammatory type.

In a cohort of 34 patients with significan CD8+ lymphocyte infiltration and a high PD-1/TIM3 expression ratio (regardless of HPV status and smoking status) showed an increase in overall survival (84 months vs. 13 months) with anti-PD-1 treatment, compared with non-inflammatory tumors[23].

The estimation of the mutational load (TMB) in the primary tumor, but also from the circulating DNA could also become a predictive biomarker[24].

There is also evidence that HPV-positive tumors may be better able to respond to anti-PD1. There is indeed a biological rationale for better efficacy of anti-PD1 in HPV + tumors since they show more immune infiltrates and more markers of activated T cells. A retrospective analysis of 54 patients treated after platinum failure with pembrolizumab (32 patients) or nivolumab (22) overall survival was significantly better for HPV positive patients: 17 months vs. 4.5 months. Similarly, the duration of anti-PD1 treatment was significantly increased in positive HPV: 7 months vs. 3 months[25].

Much simpler, a study presented at ASCO 2018 has recently been shown to have a high lymphocyte neutrophil count associated with tumor inflammation and poor prognosis[26]. The 114 patients were treated with anti-PD1 classified in 4 quartiles according to this ratio. Patients with the lowest ratio had an overall survival well above 12.5 months compared to those with the highest ratio (4.1 months, P <0.0001). In this cohort, PD-L1 expression did not discriminate patients. Thus, a very simple and clinical marker proves to be a powerful prognostic factor for the efficacy of immunotherapies.


Squamous cell carcinoma of the head and neck has not been spared by the revolution of immunotherapy. Indeed, the CPIs are now an integral part of the therapeutic arsenal and new indications are emerging either as monotherapy or in combination. In addition, many other classes of molecules are currently under development. The selection of patients who will benefit most from immunotherapy with new biomarkers remains an important challenge in the use of these new therapies. The question of the optimal duration and determination of the best combinations of these immunotherapy treatments remains unresolved. The therapeutic management of HNSCC cancers will continue to be disrupted in the coming years.
