PURPOSE Mutations in the HRAS (m HRAS) proto-oncogene occur in 4%-8% of patients with recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). Tipifarnib is a farnesyltransferase inhibitor that disrupts HRAS function. We evaluated the efficacy of tipifarnib in patients with R/M m HRAS HNSCC. METHODS We enrolled 30 patients with R/M HNSCC in a single-arm, open-label phase II trial of tipifarnib for m HRAS malignancies; one additional patient was treated on an expanded access program. After an ad hoc analysis of the first 16 patients with HNSCC with m HRAS variant allele frequency (VAF) data, enrollment was limited to those with a m HRAS VAF of ≥ 20% (high VAF). The primary end point was objective response rate. Secondary end points included assessing safety and tolerability. Patients received tipifarnib 600 or 900 mg orally twice daily on days 1-7 and 15-21 of 28-day cycles. RESULTS Of the 22 patients with HNSCC with high VAF, 20 were evaluable for response at the time of data cutoff. Objective response rate for evaluable patients with high-VAF HNSCC was 55% (95% CI, 31.5 to 76.9). Median progression-free survival on tipifarnib was 5.6 months (95% CI, 3.6 to 16.4) versus 3.6 months (95% CI, 1.3 to 5.2) on last prior therapy. Median overall survival was 15.4 months (95% CI, 7.0 to 29.7). The most frequent treatment-emergent adverse events among the 30 patients with HNSCC were anemia (37%) and lymphopenia (13%). CONCLUSION Tipifarnib demonstrated encouraging efficacy in patients with R/M HNSCC with HRAS mutations for whom limited therapeutic options exist ( NCT02383927 ).

TPS3648 Background: Trophoblast cell surface antigen (Trop-2) is highly expressed in many epithelial cancers (non–small-cell lung cancer [NSCLC], endometrial cancer, urothelial carcinoma [UC], and triple-negative breast cancer [TNBC]) and has been linked to aggressive disease and poor prognosis. SG is a Trop-2–directed antibody drug conjugate containing SN-38 (active metabolite of irinotecan) with a 7.5:1 drug-to-antibody ratio and unique hydrolyzable linker that allows for extracellular bystander effect. The phase 1/2 IMMU-132-01 basket study reported clinical activity with SG in patients with multiple tumor types not selected for Trop-2 expression including NSCLC (objective response rate [ORR]: 17%), TNBC (ORR: 33%), and UC (ORR: 31%).1-3 Results from the overall safety population (N=420) from this study found that SG was tolerable, with a predictable and manageable safety profile, and low discontinuation rates due to AEs. Methods: To test a biomarker-enrichment strategy with Trop-2, the TROPiCS-03 (TROP-2 Investigations in Cancer with SG) study was initiated. TROPiCS-03 (NCT03964727) is a multi-cohort, open-label, phase 2 study in patients with metastatic solid tumors - presently NSCLC (adenocarcinoma and squamous cell carcinoma), head and neck squamous cell carcinoma, and endometrial cancer - selected based on elevated Trop-2 expression by a validated IHC assay. Patients receive SG (10 mg/kg IV, days 1 and 8 every 21 days) and continue treatment until lack of clinical benefit or unacceptable toxicity. The primary endpoint is objective response rate (local assessment) and additional endpoints include clinical benefit rate, duration of response, progression-free survival, and safety. Females or males ≥18 years old who are histologically documented to have locally advanced or metastatic (M1, stage 4) solid tumors of the above types are eligible. Patients must have ECOG 0 or 1 and adequate clinical laboratory results to be enrolled. All subjects will have progressed after prior platinum-based chemotherapy and programmed death-ligand 1 (PD-L1) or programmed cell death protein 1 (PD-1) directed therapy. Patients who have previously received topoisomerase I inhibitors and those with known active CNS metastases are excluded. Approximately 160 patients will be enrolled in the trial overall; enrollment in the NSCLC cohort is currently in progress. References: Heist RS et al.

Purpose To determine the phase II dose and objective response rate of erlotinib, a selective epidermal growth factor receptor tyrosine kinase inhibitor, in combination with cisplatin in patients with recurrent or metastatic squamous cell carcinoma of the head and neck (HNSCC). Patients and Methods HNSCC patients with no prior chemotherapy and measurable disease were treated in three escalating-dose cohorts of daily continuous oral (PO) erlotinib and intermittent intravenous (IV) cisplatin given every 21 days. The recommended phase II dose (RPTD) was then evaluated in a two-stage trial with a primary end point of objective response rate. Results A total of 51 patients were enrolled. The RPTD was identified as erlotinib 100 mg PO daily and cisplatin 75 mg/m2 IV every 21 days. Forty-five patients were treated at the RPTD, of which 44 and 43 were eligible for toxicity and efficacy evaluations, respectively. The intention-to-treat response rate was 21%, with one complete and eight partial responses (95% CI, 10% to 36%), and disease stabilization was achieved in 21 patients (49%; 95% CI, 33% to 65%). Median progression-free survival was 3.3 months (95% CI, 2.7 to 4.8 months) and median overall survival was 7.9 (95% CI, 5.6 to 9.5) months. The combination was well tolerated, with minimal grade 3 or higher toxicity. Subgroup analysis suggested that patients who developed higher grade skin rashes during cycle 1 had better survival outcomes (P = .034). Conclusion This schedule of erlotinib and cisplatin has a favorable toxicity profile and has antitumor activity in HNSCC comparable to standard combination chemotherapy regimens.

5534 Notice of Retraction: "Phase II study of biweekly dose-intense docetaxel plus gemcitabine (GEM/DOC) in patients with recurrent locoregional or metastatic head and neck squamous cell carcinoma." ASCO's Confidentiality Policy requires that abstracts be considered confidential and embargoed from the time of submission until the findings have been publicly released in conjunction with the ASCO Annual Meeting. Abstract 5534, published in the 2012 Annual Meeting Proceedings Part I, a supplement to the Journal of Clinical Oncology, violated this policy and has been retracted from publication and presentation at the 2012 ASCO Annual Meeting. Background: Patients with metastatic head and neck squamous cell carcinoma (HNSCC) have a poor prognosis, limited treatment options, and median survival of 6 to 9 months. Docetaxel and gemcitabine have both shown activity in HNSCC. The optimal combination, dosing, and scheduling of both drugs is, however, unknown. Thus, we investigated the efficacy and safety of biweekly dose intense GEM/DOC in patients with recurrent locoregional or metastatic HNSCC. Methods: An open-label, single-institution, single-arm, phase II study was conducted for patients who were previously treated with no more than two cytotoxic regimens. The patients received docetaxel (60 mg/m2IV) and gemcitabine (3000 mg/m2 IV) on day 1. The treatments were repeated every 14 days (one cycle), until disease progression or unacceptable toxicity. The primary end point was response rate. RECIST-defined response was evaluated every 4 cycles and toxicities were evaluated at each cycle. Results: A total of 36 patients were enrolled (M:F 26:10; median age (range), 60 years (46-79); performance status 0-1) , 29 of whom were response-evaluable. The patients received a median of 4 cycles (range 0-24). Of these 29 patients, none achieved complete response (CR) and 6 demonstrated a partial response (PR). Thus, the overall response rate was 21% (95% confidence interval [CI], 0.10 – 0.38). Ten patients had stable disease (SD), resulting in tumor control (CR or PR or SD) in 16 of 29 patients (55%), whereas 13 patients (45%) had disease progression. The median response duration was 3.2 months (80% CI: 2.0 – 6.1 months). For all 36 patients, the median overall survival was 4.2 months (95% CI: 2.4 – 7.0 months). Myelosuppression was the most common adverse event. Grade 3-4 neutropenia and anemia were observed in 10 (30%) and 13 (39%) patients, respectively. None of these patients, however, had febrile neutropenia or bleeding events, and there were no treatment-related deaths. Conclusions: The combination of biweekly dose intense GEM/DOC was tolerable and active regimen in patients with recurrent locoregional or metastatic HNSCC. Our findings warrant further investigation in a larger patient population.

e17032 Background: Cetuximab (CTx) is used in treatment of locally advanced (LAD) head and neck squamous cell carcinoma (HNSCC) in combination with radiotherapy (RT) or in metastatic disease (MD). There is no comparison between CTx plus RT and cisplatin plus RT. Patients treated with CTx in daily clinical practice are frequently different from the selected population treated in clinical trials. There are no biomarkers for efficacy of CTx in HNSCC. EGFR variant 3 mutation (EGFRv3), an extracellular domain mutation of EGFR, has been reported in different frequencies in HNSCC in the last years and its association with prognosis and CTx efficacy is still unknown. Methods: Retrospective review of data from patients with HNSCC treated with CTx at a single institution from 2007 to 2010. We evaluated CTx efficacy and expression of EGFRv3, EGFR, PTEN, CD44 and CD44v6 and their impact in objective response rate (ORR), progression free survival (PFS) and overall survival (OS). Biomarkers were analyzed by immunohistochemistry in tissue microarray. Results: For a median follow-up time of 13 months, 61 patients with LAD treated with RT plus CTx had a median OS of 22.7 months, and a median PFS of 8.0 months. Age adjusted Charlson Comorbidity Index (AA-CCI) and ECOG performance status were the most important predictors of poor prognosis in this population. For a median follow-up time of 10.9 months, 44 patients with MD had a median OS of 13.0 months and a median PFS of 7.0 months, for an ORR of 53.7%. EGFRv3 was expressed in 27.1% of tumor samples and was not associated with any clinical outcome. EGFR positivity was associated to higher ORR in LAD and PTEN negativity was associated with shorter OS in the MD setting. Conclusions: In a non selected population with LAD treatment results with CTx in combination with radiotherapy were worse than expected by the phase III study, median OS 22.7 months vs 49.0 months. This difference may be attributed to different population characteristics with higher ECOG and AA-CCI in our study and warrants an adequate proof of efficacy of CTx in this population. EGFRv3 is present in HNSCC but does not impact prognosis. PTEN and EGFR expression emerged as potential biomarkers in HNSCC patients treated with CTx.

TPS6096 Background: Novel agents are often investigated in unselected end-stage cancer patients and their efficacy is evaluated by the classical RECIST criteria making unlikely to fully exploit the antitumor potential of these targeted agents. Olaparib (O) is a potent inhibitor of PARP especially active in tumors that have homologous recombination DNA repair pathway deficiencies. Durvalumab (D) is a selective, high-affinity human IgG1 monoclonal antibody that blocks PD-L1 binding to PD-1 and CD80, overcoming PD-L1-mediated inhibition of T-cell activation. There is substantial evidence that tumor cells use PARP to repair platinum-induced DNA damage and thus escape apoptosis. In addition, O may complement the antitumor activity of D by increasing DNA damage through repair inhibition. Methods: OPHELIA is an open-label randomized multicenter phase II (window) trial in patients (pts) with head and neck squamous cell carcinoma (HNSCC). Treatment-naive HNSCC pts selected for primary curative study are randomized 3:3:3:1 in 4 neoadjuvant treatment groups: D 1500 mg on day 1 followed by O 600mg daily for 21-28 days (12 pts), cisplatin 60 mg/m2 on day 1 followed by O 75mg daily for 5 days (12 pts), monotherapy with O 600mg daily for 21-28 days (12 pts) and no treatment (5 pts). Preoperative therapy is discontinued 24 to 36 hours before surgery. Tumor biopsies, CT scans, PET and blood specimens are obtained at diagnosis and at surgery. Primary endpoint is the change in the tumor Ki-67 before and after treatment. Secondary endpoints are objective response rate according to RECIST 1.1 criteria, pathologic complete response rate and metabolic response rate assessed by FDG-PET/CT scan. Exploratory endpoints will include tumor and blood biomarkers. Translational correlates will be tested in tumor tissue, plasma and germline DNA and will include mutations in genes associated with DNA repair assessed by next generation sequencing and circulating tumor cells (CTCs) evaluated for DNA repair biomarkers and PD-L1. Trial is open to enrollment. Clinical trial information: NCT02882308.

TPS6089 Background: PD-1 blockade ± chemotherapy has recently become a primary systemic therapy recommended by NCCN guidelines for patients (pts) with recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). However, most pts still do not respond to treatment, indicating a large unmet need for pts with unresectable disease. CMP-001 is a toll-like receptor 9 (TLR9) agonist comprising a CpG-A oligodeoxynucleotide packaged in a virus-like particle that can induce type I interferon secretion from tumor-associated plasmacytoid dendritic cells, promoting a Th1-like chemokine milieu in the tumor microenvironment and inducing an antitumor CD8+ T-cell response. In a phase (ph) 1b study in pts with metastatic melanoma, intratumoral (IT) injection of CMP-001 + intravenous (IV) pembrolizumab (pembro) reversed PD-1 blockade resistance, induced responses in injected and noninjected lesions, and had an acceptable safety profile (Milhem et al, SITC 2020). This combination is therefore being tested in pts with HNSCC. Methods: CMP-001-007 (NCT04633278) is an open-label, multicenter, ph 2 study designed to investigate the efficacy and safety of CMP-001 + IV pembro in adult pts with histologically or cytologically confirmed R/M HNSCC considered incurable by local therapies. Eligible pts have undergone a pretreatment tumor biopsy, received no prior systemic therapy in the R/M setting, and have primary tumor locations of oropharynx, oral cavity, hypopharynx, or larynx. In addition, pts must have PD-L1-positive tumors (combined positive score ≥1), known tumor human papillomavirus (HPV) status (for oropharyngeal cancer), and measurable disease per RECIST v1.1 with ≥1 lesion amenable to IT injection. Pts with primary tumors in the nasopharynx are excluded. Enrolled pts will receive CMP-001 10 mg once weekly for 7 doses and every 3 weeks (Q3W) thereafter. The first dose may be administered subcutaneously or via IT injection, with all subsequent doses administered IT. All pts will also receive pembro 200 mg IV Q3W after the CMP-001 injection. Treatment continues until unacceptable toxicity or disease progression. The primary endpoint is investigator-assessed objective response rate (ORR) per RECIST v1.1. Secondary endpoints include safety, duration of response (DOR), progression-free survival (PFS), overall survival, and effects of HPV infection and PD-L1 expression on ORR, DOR, and PFS. Exploratory endpoints include analyses of baseline and changes from baseline in tumor or serum biomarkers related to TLR9, immune checkpoints, and potential predictors of response, as well as serum concentrations of CXCL10 and CMP-001. Refer to clinicaltrials.gov/ct2/show/NCT04633278 for the most current information on enrolling sites. Clinical trial information: NCT04633278.

Abscopal Effect

6034 Background: This phase 2 study investigated whether durvalumab plus tremelimumab with proton therapy improves objective response rate (ORR), overall survival (OS), and progression-free survival (PFS) in heavily treated recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) via boosting abscopal effect. Methods: Thirty-one patients who have previously received more than one chemotherapy regimen, including at least one platinum-based regimen and have at least two measurable lesions enrolled at Samsung medical center. Patients received durvalumab 1500mg intravenously (IV) in combined with tremelimumab 75 mg IV every four weeks for four cycles followed by durvalumab 1500mg every four weeks. After one cycle of durvalumab and tremelimumab combination, proton therapy was performed with a total dose of 25 Gy in 5-Gy daily fractions to one of the measurable lesions. We assessed the target lesion response outside the radiation field by RECIST criteria 1.1 to evaluate the abscopal effect. Results: Between March 2018 and July 2020, 31 patients were enrolled. The median age was 59 years, and median two prior chemotherapy regimens were administered. With 24.8 months of follow-up, the median number of cycles of immunotherapy was three. The ORR was 27.3%, including one complete response and five partial responses. Median OS was 6.4 months (95% CI, 1.0 to 11.8), and median PFS was 2.4 months (95% CI, 0.6 to 4.2). Median duration of response was 15.9 months (range 3.7 – 21.2). Grade 3 or higher adverse events were observed in 6 (27.3%) patients; anemia (n = 1), constipation (n = 1), electrolyte imbalance (n = 2), hyperglycemia (n = 1), pneumonia (n = 1). Conclusions: Combination of durvalumab/tremelimuab with proton therapy is well tolerable and shows encouraging anti-tumor efficacy in non-irradiated tumor lesions of heavily treated HNSCC patients. These results suggest that the combination of immunotherapy with proton therapy might enhance the abscopal effect. Clinical trial information: NCT03450967.
