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.

The development of cyclin-dependent kinase (CDK) 4/6 inhibitors has been more prominent in hormone receptor (HR)-positive human epidermal growth factor receptor 2 (HER2)-negative breast cancers, with a significant improvement in progression-free survival (PFS) in first and later lines of metastatic breast cancer (MBC) therapy. Preclinical evidence suggests that there is activity of CDK4/6 inhibitors in nonluminal cell lines. Here, we present a review of the current preclinical and clinical data on the use of CDK inhibitors in HER2-positive and triple-negative breast cancer (TNBC).

7586 Background: Cetuximab, an IgG1 monoclonal antibody targeting the epidermal growth factor receptor (EGFR) on both normal and tumor cells, has been investigated in advanced NSCLC as a single agent and in combination with chemotherapy. This ongoing randomized phase II open-label trial evaluates cetuximab in combination with carboplatin (Cb) and paclitaxel (Pac) when given in two dose schedules to patients (pts) with previously untreated stage IIIB/IV NSCLC. Methods: Eligible pts were randomized to 1 of 2 treatment arms. Cetuximab treatment was identical in both arms: 400 mg/m2 IV on day 1 and 250 mg/m2 weekly thereafter. Beginning on day 8, a schedule of Cb AUC=6 IV and Pac 225 mg/m2 IV given on a 3-week cycle was compared with a schedule of Cb AUC=6 IV q4 weeks and Pac 100 mg/m2 IV given weekly for 3 weeks of each 4-week cycle. Pts who achieve CR, PR, or SD after 4 cycles may continue weekly cetuximab monotherapy until disease progression or unacceptable toxicity. The primary objectives were to estimate median progression-free survival (PFS) and the PFS rate at 6 months. Secondary objectives included response rate. Results: The study has completed accrual, with 168 pts randomized and 165 treated. Data are available for 164 pts and confirmed responses for 155 pts. Conclusions: Cetuximab combined with Cb and Pac in both dose schedules demonstrated activity and an acceptable toxicity profile in pts with NSCLC. Final PFS and overall survival data are pending. No significant financial relationships to disclose. [Table: see text]

Overexpression of the human epidermal growth factor receptor (HER2) oncoprotein in breast cancer patients, is one of the biological characteristics of the disease that determines the choice of appropriate systemic treatment. We report the case of a 41-year-old woman, with relapsing HER2-positive breast cancer in cerebral and pulmonary cells. The patient underwent multimodal first Iine treatment including pertuzumab, trastuzumab and docetaxel and panencephalic radiotherapy with good response and progression-free survival for approximately 16 months. Subsequently, further to a encephalic progression of the disease, the patient was treated in second line with the combination lapatinib + capecitabine which induced further encephalic response and disease control for additional 20 months (Oncology).

TPS1097 Background: Tucatinib (TUC) is an oral, reversible, small molecule tyrosine kinase inhibitor highly selective for human epidermal growth factor receptor 2 (HER2) with minimal inhibition of human epidermal growth factor receptor (EGFR). In the pivotal, randomized HER2CLIMB trial (NCT02614794), the combination of TUC + trastuzumab (T) + capecitabine (C) demonstrated statistically significant and clinically meaningful improvements in progression free survival (PFS), overall survival (OS), and PFS in patients (pts) with brain metastases (BM), compared to T + C alone. These data supported regulatory approvals in the US and internationally for TUC in combination with T + C in pts with HER2+ metastatic breast cancer (MBC). Trastuzumab deruxtecan (T-DXd) is an antibody-drug conjugate of trastuzumab and a topoisomerase I inhibitor payload approved in the US for treatment of HER2+ MBC in pts who have received 2 or more prior anti-HER2 regimens in the metastatic setting. Approval was based on data from the single arm Destiny-Breast01 trial (NCT03248492) where treatment with T-DXd resulted in a confirmed objective response rate (cORR) of 61.4% (95% CI: 54.0, 68.5) in pts with HER2+ MBC who had prior ado-trastuzumab emtansine treatment. Despite these advances, HER2+ MBC remains incurable, and pts will eventually progress on currently available therapies. Combining TUC and T-DXd may result in further improvement on the efficacy seen with either agent alone. Methods: HER2CLIMB-04 (NCT04539938) is a single arm, open-label phase 2 trial evaluating safety and antitumor activity of TUC + T-DXd in pts with HER2+ unresectable locally-advanced or MBC who have received 2 or more prior HER2-based regimens in the metastatic setting. Pts with BM, including active BM, may be enrolled. Ten pts will be enrolled in the safety lead-in portion of the trial and followed for at least 1 cycle. If safety of the combination is acceptable, the trial will continue until approximately 60 response-evaluable pts have been enrolled, approximately evenly distributed between pts with and without BM. The primary endpoint is cORR by investigator (INV) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Secondary endpoints are PFS, duration of response (DOR), and disease control rate (DCR) by INV per RECIST v1.1, OS, and safety. Exploratory endpoints will include cORR, PFS, DOR, DCR by independent central review per RECIST v1.1, pharmacokinetic analyses, biomarker analyses, and changes in patient-reported outcomes using the European Quality of Life 5-Dimension 5-Level instrument. Enrollment began in late 2020 in the United States. Clinical trial information: NCT04539938 .

e12508 Background: Metronomic chemotherapy is an emerging paradigm of cancer therapy in which low doses of chemotherapy are delivered at frequent intervals. Activity in patients with metastatic breast cancer (MBC) has been demonstrated in several phase II clinical trials. Methods: We proposed a regimen with metronomic chemotherapy and dual HER2 inhibition in HER2 positive patients with MBC. We hypothesized that this regimen will be highly active in MBC and have a favorable toxicity profile. Patients were treated on a 21-day cycle with capecitabine 1500mg PO daily, cyclophosphamide 50mg daily, lapatinib 1000mg PO daily and trastuzumab 6mg/kg IV once per 21-day cycle. This regimen was continued until disease progression or unacceptable toxicity. Primary endpoint was progression free survival (PFS). Secondary endpoints were overall response rate (ORR), clinical benefit rate (CBR), overall survival (OS), and safety and tolerability of this regimen. Eligibility criteria were patients 18 years of age and older who had histologically confirmed HER2-positive metastatic breast cancer with prior trastuzumab use in the adjuvant or metastatic setting with no more than two prior regimens for MBC. Results: Ten patients were accrued from Jan 2014-Oct 2016. Median age was 52 (range 38 - 79) years. Median number of chemotherapy regimens for metastatic disease was 0.5 (range 0-2). Median PFS was 13.7 (95% CI: 2.6, 16.6) months. Median OS was 29.6 (95% CI: 11.8, 60.5+) months. ORR was 30%, and CBR was 70%. Grade 3 or 4 toxicities were identified in 6 patients. The most common toxicities of any grade were fatigue (100%), diarrhea (80%), anemia, neutropenia, ALT increase, nausea and hand-foot syndrome 50% each. One patient achieved CR for over 3 years and continues on treatment at time of this report. 8 patients progressed and 1 patient withdrew from study without response evaluation. The trial was closed due to lack of accrual. Conclusions: The proposed regimen of metronomic capecitabine and cyclophosphamide with lapatinib and trastuzumab appears to be active in patients with HER2 positive MBC but with significant toxicity. Clinical trial information: NCT01873833.

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.

TPS653 Background: Pertuzumab (P) is a humanized monoclonal antibody directed against the dimerization domain of HER2: it prevents HER2 heterodimerization and thus activation of downstream signaling. Since P targets a different epitope than trastuzumab (H), a more comprehensive HER2 blockade is achieved by combining the two agents. Data from CLEOPATRA showed improved efficacy for P and H plus docetaxel. The combination of P and H has not yet been assessed with other chemotherapy partners in the metastatic setting. H plus vinorelbine (V) has shown comparable efficacy to H plus docetaxel but with a superior safety profile. VELVET will assess the overall response rate (ORR) of P with H+V in first-line patients (pts) with HER2-positive MBC. Co-administration of P and H within the same infusion bag will also be investigated as this could increase pt convenience by reducing administration and observation time. Methods: VELVET is a multicenter, open-label, two-cohort, Phase II trial. Pts with HER2-positive LABC or MBC not previously treated in the metastatic setting with non-hormonal anticancer therapy are eligible. Pts must have an LVEF >55% at baseline and an ECOG PS of 0 or 1. Study enrollment started in January 2012. A total of 210 pts will be included. Based on statistical assumptions, 95 pts must be evaluable per cohort, which assumes a withdrawal rate around 10%. Pts in Cohort 1 (the first 105 pts enrolled) will receive P and H sequentially and pts in Cohort 2 (the next 105 pts) will receive P and H in the same infusion bag at Cycle 2 onwards if drug administration in Cycle 1 was well tolerated. V will be given in both cohorts. Treatment duration is until disease progression or unacceptable toxicity. Study dose: P: 840 mg loading dose, 420 mg q3w (iv); H: 8 mg/kg loading dose, 6 mg/kg q3w (iv), and V: 25 mg/m2 Day 1 and 8 (first cycle) then 30−35 mg/m2 Day 1 and 8 q3w (iv) (dose escalation at investigator’s discretion). The primary endpoint is ORR by independent assessment. Secondary endpoints include investigator assessment of ORR, time to response, duration of response, PFS, time to progression, overall survival, safety and tolerability, and QoL.

Abstract Background Trastuzumab and fulvestrant combination therapy is one of the treatment options for patients with hormone receptor- and human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer; however, there are limited studies evaluating the efficacy of this combination therapy. Methods We retrospectively reviewed the data of women with hormone receptor- and HER2-positive metastatic breast cancer who received trastuzumab and fulvestrant combination therapy between August 1997 and August 2020 at the Cancer Institute Hospital. The primary endpoint of this study was progression-free survival, and the secondary endpoints were response rate, overall survival and safety. Results We reviewed the data of 1612 patients with recurrent or metastatic breast cancer, of which 118 patients were diagnosed with hormone receptor- and HER2-positive breast cancer. Of these, 28 patients who received trastuzumab and fulvestrant combination therapy were eligible for this study. The median treatment line for advanced breast cancer was 6 (range, 1–14), the median progression-free survival was 6.4 months (95% confidence interval [CI], 3.46–8.17), and the median overall survival was 35.3 months (95% CI, 20.0–46.7). Of the 28 patients, partial response was observed in 1 (4%), stable disease in 17 (61%), and progressive disease in 10 (36%) patients. The disease control rate was 64%. Adverse events of grade ≥ 3 were not observed. Conclusions Trastuzumab and fulvestrant combination therapy showed moderate clinical efficacy and no severe toxicity after standard anti-HER2 treatment, which is a reasonable treatment option for patients with hormone receptor- and HER2-positive metastatic breast cancer. These data contribute to understanding the efficacy of trastuzumab and fulvestrant combination therapy as control data for further development of anti-HER2 agents plus hormone therapy.
