Abstract Background Standard therapy for human epidermal growth factor receptor 2 (HER2)-mutant non-small-cell lung cancer (NSCLC) is lacking. The clinical benefits with pan-HER inhibitors (afatinib, neratinib, and dacomitinib), anti-HER2 antibody drug conjugate (ADC) trastuzumab emtansine, and an emerging irreversible tyrosine kinase inhibitor (TKI) poziotinib were modest. Another new ADC trastuzumab deruxtecan showed encouraging outcomes, but only phase I study was completed. Pyrotinib, another emerging irreversible epidermal growth factor receptor (EGFR)/HER2 dual TKI, has been approved in HER2-positive breast cancer in 2018 in China. It has shown promising antitumor activity against HER2-mutant NSCLC in phase II trials, but pyrotinib-related diarrhea remains an issue. The antiangiogenic and immunomodulatory drug thalidomide is a cereblon-based molecular glue that can induce the degradation of the IKAROS family transcription factors IKZF1 and IKZF3. The use of thalidomide can also decrease gastrointestinal toxicity induced by anti-cancer therapy. Methods This is an open-label, single-arm phase II trial. A total of 39 advanced NSCLC patients with HER2 exon 20 insertions and ≤ 2 lines of prior chemotherapy will be recruited, including treatment-naïve patients who refuse chemotherapy. Patients are allowed to have prior therapy with immune checkpoint inhibitors and/or antiangiogenic agents. Those who have prior HER2-targeting therapy or other gene alterations with available targeted drugs are excluded. Eligible patients will receive oral pyrotinib 400 mg once daily and oral thalidomide 200 mg once daily until disease progression or intolerable toxicity. The primary endpoint is objective response rate. Discussion The addition of thalidomide to pyrotinib is expected to increase the clinical benefit in advanced NSCLC patients with HER2 exon 20 insertions, and reduce the incidence of pyrotinib-related diarrhea. We believe thalidomide is the stone that can hit two birds. Trial registration ClinicalTrials.gov Identifier: NCT04382300. Registered on May 11, 2020.

516 Background: Lapatinib (L) is approved for the treatment of human epidermal growth factor receptor 2 (HER2) positive MBC in combination with capecitabine (C) following progression after trastuzumab, anthracyclines and taxanes. Vinorelbine (V) is an important chemotherapy option in MBC. This randomized, open-label, multicenter phase II study (NCT01013740) evaluated the efficacy and safety of L with either V or C in women with HER2+ MBC. The analysis of progression-free survival (PFS) and safety showed comparable rates of efficacy and tolerability between the 2 arms (Janni et al, SABCS 2012). Here we report the results of the overall survival (OS) and crossover analyses. Methods: Patients with MBC who had received ≤1 chemotherapy regimen in the metastatic setting were randomized 2:1 to either L 1250 mg orally once daily (QD) continuously + V 20 mg/m2 intravenously on days 1 and 8, every 3 weeks, or L 1250 mg orally QD continuously + C 2000 mg/m2/day orally in 2 doses, 12 hours apart on days 1-14 every 3 weeks. Patients were stratified by prior receipt of therapy for MBC and site of metastatic disease. The primary endpoint was PFS. Other endpoints included OS, overall response rate and safety. Patients progressing on one treatment arm were given the option of crossover to the other arm. All analyses were conducted with a descriptive intent only. The control arm of L+C was included in the study design to validate the patient population and lend support to the activity of L+V. Results: 112 patients were randomized in the study; 37 to the L+C arm and 75 to the L+V arm. The median OS in the L+C arm was 19.4 months [95% CI: 16.4-27.2] and 24.3 months [95% CI: 16.4-NE] in the L+V arm. At the time of analysis 42 patients had crossed over; 29 patients to L+C and 13 to L+V. Median PFS after crossover was 4 months [95% CI: 2.1-5.8] in the L+C arm and 3.2 months [95% CI: 1.7-5.1] in the L+V arm. Conclusions: L+V has shown consistent median OS with that reported in the pivotal study of L+C. The exploratory analysis of patients retreated with L after progression on L supports the biological rationale for maintaining HER2 suppression in HER2+ patients with progression on prior lines of anti-HER2 agents. Clinical trial information: NCT01013740.

Background: Tyrosine kinase inhibitors (TKIs) show variable efficacy in epidermal growth factor receptor mutation-positive (EGFR+) NSCLC patients, even in patients harbouring the same mutation. Co-alterations may predict different outcomes to TKIs. Methods: We retrospectively analysed all consecutive EGFR+ advanced NSCLC treated with first-line TKIs at our Institutions. NGS with a 22 genes clinical panel was performed on diagnostic specimens. PD-L1 expression was also evaluated. Results: Of the 106 analysed specimens, 59 showed concomitant pathogenic mutations. No differences in OS (mOS 22.8 vs. 29.5 months; p = 0.088), PFS (mPFS 10.9 vs. 11.2 months; p = 0.415) and ORR (55.9% vs. 68.1%; p = 0.202) were observed comparing patients without and with co-alterations. Subgroup analysis by EGFR mutation type and TKIs generation (1st/2nd vs. 3rd) did not show any difference too. No correlations of PD-L1 expression levels by co-mutational status were found. Significant associations with presence of co-alterations and younger age (p = 0.018) and baseline lymph nodes metastases (p = 0.032) were observed. Patients without concomitant alterations had a significant higher risk of bone progression (26.5% vs. 3.3%, p = 0.011). Conclusions: Pathogenic co-alterations does not seem to predict survival nor efficacy of EGFR TKIs in previously untreated advanced NSCLC.

PurposeSorafenib is an oral multikinase inhibitor that targets the Ras/Raf/MEK/ERK mitogenic signaling pathway and the angiogenic receptor tyrosine kinases, vascular endothelial growth factor receptor 2 and platelet-derived growth factor receptor β. We evaluated the antitumor response and tolerability of sorafenib in patients with relapsed or refractory, advanced non–small-cell lung cancer (NSCLC), most of whom had received prior platinum-based chemotherapy.Patients and MethodsThis was a phase II, single-arm, multicenter study. Patients with relapsed or refractory advanced NSCLC received sorafenib 400 mg orally twice daily until tumor progression or an unacceptable drug-related toxicity occurred. The primary objective was to measure response rate.ResultsOf 54 patients enrolled, 52 received sorafenib. The predominant histologies were adenocarcinoma (54%) and squamous cell carcinoma (31%). No complete or partial responses were observed. Stable disease (SD) was achieved in 30 (59%) of the 51 patients who were evaluable for efficacy. Four patients with SD developed tumor cavitation. Median progression-free survival (PFS) was 2.7 months, and median overall survival was 6.7 months. Patients with SD had a median PFS of 5.5 months. Major grades 3 to 4, treatment-related toxicities included hand-foot skin reaction (10%), hypertension (4%), fatigue (2%), and diarrhea (2%). Nine patients died within a 30-day period after discontinuing sorafenib, and one patient experienced pulmonary hemorrhage that was considered drug related.ConclusionContinuous treatment with sorafenib 400 mg twice daily was associated with disease stabilization in patients with advanced NSCLC. The broad activity of sorafenib and its acceptable toxicity profile suggest that additional investigation of sorafenib as therapy for patients with NSCLC is warranted.

In non-small cell lung cancer (NSCLC), the identification of epidermal growth factor receptor (EGFR) mutations and the parallel development of EGFR tyrosine kinase inhibitors (TKIs) have radically changed the therapeutic management strategies. Currently, erlotinib, gefitinib, and afatinib are all approved as standard first-line treatment in EGFR-mutated NSCLC. However, despite the proven efficacy, some EGFR-mutated NSCLCs do not respond to EGFR TKIs, while some patients, after a favorable and prolonged response to EGFR TKIs, inevitably progress within about 10-14 months. Epidermal growth factor receptor-dependent mechanisms, activation of alternative pathways, or phenotypic transformation can cause the resistance to EGFR TKIs. The exon 20 p.Thr790Met point mutation (T790M) is responsible for about 60% of cases of resistance when progression occurs. A third-generation TKI, osimertinib, improved outcome in patients harboring T790M after first- and second-generation TKI treatment. However, resistance develops even after treatment with third-generation drugs. To date, the Cys797Ser (C797S) mutation in exon 20 of EGFR is the most well-known resistance mutation after osimertinib. Fourth-generation TKIs are already under development. Nevertheless, additional information is needed to better understand and effectively overcome resistance. The aim of this review is to report recent advances and future perspectives in the treatment of EGFR-mutated NSCLC, highlighting the resistance mechanisms that underlie disease progression.

Epidermal growth factor receptor gene exon 20 insertion mutations are seen in ∼4–12% of patients with epidermal growth factor receptor-mutant non-small cell lung cancer. However, there is no targeted therapy approved for the treatment of non-small cell lung cancer patients with these rare epidermal growth factor receptor mutations. Previous studies revealed that epidermal growth factor receptor gene exon 20 insertion mutations are unique in their ability to activate epidermal growth factor receptor without the typical structural changes associated with the common epidermal growth factor receptor mutations, reducing the clinical efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors currently approved for non-small cell lung cancer. Therefore, there is an urgent need to identify active epidermal growth factor receptor-tyrosine kinase inhibitors and other effective treatment strategies for non-small cell lung cancer patients with epidermal growth factor receptor gene exon 20 insertion mutations. Mobocertinib is a novel irreversible epidermal growth factor receptor-tyrosine kinase inhibitor that selectively targets epidermal growth factor receptor gene exon 20 insertion mutations. Preclinical study revealed that mobocertinib inhibited the viability of epidermal growth factor receptor gene exon 20 insertion mutations-driven patient-derived xenografts and murine orthotopic tumors more potently than traditional epidermal growth factor receptor-tyrosine kinase inhibitors. In a study recently published in Cancer Discovery, Gonzalvez et al. assessed the safety, tolerability, and antitumor efficacy of mobocertinib in metastatic non-small cell lung cancer patients with epidermal growth factor receptor gene exon 20 insertion mutations. They found that non-small cell lung cancer patients with epidermal growth factor receptor gene exon 20 insertion mutations can benefit from mobocertinib treatment. Additionally, the treatment-related toxicity of mobocertinib was manageable. These findings lay the foundation for the application of mobocertinib in epidermal growth factor receptor gene exon 20 insertion-mutated non-small cell lung cancer.

PURPOSE: To investigate safety, tolerability, dose-related pharmacologic properties, and pharmacodynamics of ZD1839 (gefinitib, Iressa; AstraZeneca Pharmacueticals, Wilmington, DE), an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, in patients with solid tumor types known to express or highly express EGFR. METHODS: This was an open-label, phase I, dose escalation safety/tolerability trial of oral ZD1839 (150 to 1,000 mg/d), administered once daily for 28-continuous-day cycles until disease progression or undue toxicity. RESULTS: Of 71 (69 assessable for safety; 58 for efficacy) patients at seven dose levels, most had non–small-cell lung (n = 39) or head and neck (n = 18) cancer, and 68 of 71 patients received prior cancer therapy (two or more regimens in 54 patients [78%]). Diarrhea and rash, the primary dose-limiting toxicities (DLTs), occurred at 800 mg. Frequent treatment-related grade 1/2 adverse events were diarrhea (55%), asthenia (44%), and acne-like follicular rash (46%). At doses ≥ 800 mg, 45% of patients required dose reductions. No increased or cumulative toxicity was observed over 250 patient-months of exposure. Pharmacokinetic analysis showed that steady-state occurred by day 7, interpatient exposure was more variable than intrapatient exposure, and variability of exposure did not change with dose. One patient experienced a partial response, but antitumor activity manifested mainly as prolonged stable disease (45% of patients ≥ 3 months, 22% ≥ 6 months, and 7.2% ≥ 1 year). No relationship between dose, response, or duration on study was observed. CONCLUSION: Rash and diarrhea, generally mild and tolerable at doses ≤ 600 mg/d, were DLTs at 800 mg/d (maximum-tolerated dose). Antitumor activity was observed at all doses. Pharmacokinetic analyses confirmed suitability of once-daily oral dosing.
