Medical Policy Herceptin® (trastuzumab) Effective Date: October 1, 2016 Subject: Herceptin® (trastuzumab) Overview: Herceptin is an anti-cancer drug used along with other medications or after other drug therapy to treat a certain type of breast cancer and other types of cancer. Policy and Coverage Criteria: NOTE: Prior Authorization is not required Harvard Pilgrim considers Herceptin (trastuzumab) medically necessary as a treatment for any of the following: breast cancer; gastric, esophageal, and gastroesphogeal cancer; leptomeningeal metastases; Harvard Pilgrim does not cover Herceptin (trastuzumab) for indications not listed above. Exclusions: N/A Supporting Information: 1. Technology Assessment: Herceptin (trastuzumab) is a recombinant humanized monoclonal antibody directed against the human epidermal growth factor receptor 2 (HER2). After binding to HER2 on the tumor cell surface, trastuzumab induces an antibody-dependent cell-mediated cytotoxicity against tumor cells that overexpress HER2. 2. Literature Review: Breast Cancer - Trastuzumab originally received approval in 1998, by the U.S. Food and Drug Administration (FDA) for the treatment of individuals with metastatic breast cancer whose tumors overexpressed HER2 (referred to as HER2+) and who had received one or more chemotherapy regimens for the metastatic disease. Additionally, trastuzumab in combination with paclitaxel as part of a first-line regimen for metastatic disease was also approved. In 2006 and 2008, trastuzumab received additional FDA approval for use in the adjuvant setting in combination therapy for individuals with positive lymph nodes or node-negative disease with high-risk features, or as a single agent following multi-modality anthracycline based therapy. Although there are different FDA approved dosing recommendations, the maximum treatment period for adjuvant therapy is 52 weeks. Treatment for metastatic breast cancer may continue until disease progression (Product Information, 2015). These indications were based on the results of a variety of randomized controlled trials studying the role of trastuzumab as a treatment of metastatic breast disease, as neoadjuvant therapy or adjuvant therapy. The trials examined the use of trastuzumab as monotherapy or in combination with a variety of other therapies and all reported improved disease free survival. In 2012, the FDA approved pertuzumab (Perjeta™, Genentech, Inc., San Francisco, CA) in combination with trastuzumab and docetaxel, for individuals with HER2+ metastatic breast cancer who have not previously received anti-HER2 therapy or chemotherapy treatment for the metastatic disease. The approval was based on the significantly improved progressionfree survival (PFS) results from the phase III, double-blind, placebo-controlled Clinical Evaluation of Pertuzumab and Trastuzumab (CLEOPATRA) trial. A total of 808 participants with HER2+ metastatic breast cancer were enrolled into the study. Participants were eligible if they did not receive prior chemotherapy for the metastatic disease. One hormonal treatment prior to randomization was allowed. The median PFS was 18.5 months for those randomized to the group treated with trastuzumab, pertuzumab and docetaxel compared to a median PFS of 12.4 months in the control group treated with placebo plus trastuzumab and docetaxel. The control group had more frequent left ventricular systolic dysfunction (8.3%) compared to the treatment group combining trastuzumab and pertuzumab (4.4%) (Baselga, 2012). Gianni and colleagues (2011) reported updated results from the ongoing phase III, randomized, open-label, multi-center international HERA (Herceptin Adjuvant) trial comparing trastuzumab treatment for 1 year and 2 years with observation after standard neoadjuvant and/or adjuvant therapy in women with early breast cancer. The interim analysis at a median 1-year follow-up demonstrated a significantly improved disease-free survival (DFS) with trastuzumab compared to chemotherapy alone (hazard ratio [HR] 0.54; 95% confidence interval [CI], 0.43-0.67). As a result, the protocol was amended in 2005, to allow individuals from the control group who had not relapsed to cross over and receive trastuzumab. Based on recommendations from the independent data monitoring committee, the 2-year trastuzumab group data are not being released until the final event-driven analysis. Planned data updates occur every 2 years for the 1-year trastuzumab treatment and the observation group. With a median follow-up of 48.4 months, Gianni presented updated data for the 1-year and observation cohorts. The 4-year disease-free survival rate in the 1-year trastuzumab treatment group was 78.6% compared to 72.2% (HR 0.76; 95% CI, 0.66-0.87; p<0.0001) for the observation group. The 4-year overall survival (OS) rate was not statistically significant with 89.3% for the trastuzumab group and 87.7 % (p=0.11) in the observation group. Of the 1698 participants in the observation group, 885 (52%) of the individuals crossed over and began trastuzumab treatment. In a comparison of the individuals in the selective crossover group, the estimated HR for fewer disease free survival events was significant (p=0.0077) compared to the observation cohort. The authors concluded that although the OS benefit was no longer statistically significant, the benefit from 1-year treatment with trastuzumab is maintained with longer follow-up. The data from treatment with 2-years of trastuzumab is still pending. It should be noted the majority of randomized studies of trastuzumab as adjuvant therapy enrolled individuals with breast cancer and positive axillary nodes, or individuals with negative nodes but with a primary tumor measuring greater than 1 cm in greatest dimension. The size limitation in individuals with negative nodes was based on the assumption that small tumors (less than 1 cm in diameter) were at low risk of recurrence such that trastuzumab would not be beneficial, particularly considering the cardiac side effects. However, in 2008, data presented at the San Antonio Breast Cancer Symposium challenged this assumption. GonzalezAngulo and colleagues (2009) performed a retrospective review of 1390 individuals with early breast cancer no larger than 1 cm in any dimension and negative axillary nodes in the Breast Cancer Management Database at the University of Texas M.D. Anderson Cancer Center (MDACC). A total of 965 individuals were eligible for the study. A second set of 350 individuals who met identical clinical criteria at 2 other institutions in Belgium and Austria were used to validate the MDACC results. Individuals were divided into three groups: triple negative (i.e., negative hormone receptors and negative HER2), HER 2+ (regardless of hormone status) and hormone receptor-positive and HER2 negative. Individuals with HER2+ breast cancer had a significantly worse relapse free survival compared to individuals with hormone-positive cancer or triple-negative breast cancer (p<0.0001). The authors concluded that individuals with even small (less than 1 cm) HER2+ tumors have a significant risk of relapse and that adjuvant systemic therapy with trastuzumab should be considered. Therefore, adjuvant trastuzumab is considered in any individual with HER 2+ early breast cancer regardless of nodal status or size of primary tumor. Blackwell and colleagues (2010) reported results from a phase III randomized study (EGF104900) of lapatinib alone or in combination with trastuzumab for women with HER2positive, trastuzumab-refractory metastatic breast cancer. A total of 296 participants were enrolled with random assignment equally to each treatment arm. Assessments were completed every 4 weeks through week 16, and then every 8 weeks thereafter. Participants were allowed to cross over to combination therapy if objective disease progression was noted after receiving a minimum of 4 weeks of monotherapy with lapatinib. In 2012, the final planned analysis of OS included 291 participants who were available for efficacy analysis with 145 in the lapatinib monotherapy group and 146 in the combination lapatinib and trastuzumab group. After progression of disease while on lapatinib monotherapy, 77 participants were allowed to cross over and received combination therapy. The primary endpoint of PFS was significantly improved in the individuals who were treated with combination trastuzumab and lapatinib compared to lapatinib monotherapy (HR, 0.71; 95% CI, 0.58 to 0.94; p=0.011). Median PFS was 11.1 weeks with combination therapy compared to 8.1 weeks PFS for monotherapy with lapatinib. The median OS was 14 months for the combination therapy versus 9.5 months for lapatinib monotherapy (HR, 0.74; 95% CI, 0.57 to 0.96; p=0.021). Adverse events had similar incidence rates of 94% in the combination cohort compared to 90% in the single-agent group. A significantly higher rate of diarrhea was noted in participants in the combination arm versus the monotherapy arm (62% vs. 48%). Serious adverse events were reported by 26% in the cohort receiving combination therapy and 16% in the cohort receiving monotherapy. The authors noted the 4.5 month survival improvement with the trastuzumab combination supports the preclinical data that "lapatinib plus trastuzumab combination has synergistic antiproliferative effects" (Blackwell, 2012). In the GBG26/BIG 3-05 phase III RCT, participants were randomized to start single agent capecitabine or continue trastuzumab and start capecitabine at the time of progressive disease while on first-line regimens that included trastuzumab. Baselga and colleagues (2012) reported there was no significant survival difference in the final OS analysis between treatment arms. However, the post-hoc analysis demonstrated a better progression survival than those who did not receive third-line anti-HER2 therapy. Post-progression survival of 18.8 months was noted in participants who continued or restarted anti-HER2 therapy after second progression compared to 13.3 months in those who did not receive third-line anti-HER2 therapy (p=0.02). The authors note that the results need to be confirmed in a larger metadatabase analysis to overcome potential bias related to the post-hoc review. The authors concluded the use of anti-HER2 therapy throughout multiple lines continues to be recommended. The clinical practice guideline (CPG) of the National Comprehensive Cancer Network® (NCCN, 2015) recommends the use of trastuzumab to treat breast cancer. The CPG recommends "continued trastuzumab following progression on first line-trastuzumab containing chemotherapy for metastatic breast cancer. The optimal duration of trastuzumab in patients with long-term control of disease is unknown." In 2014, the American Society of Clinical Oncology (ASCO) clinical practice guideline (Ramakrishna) provided recommendations for management of individuals with brain metastasis from HER2+ breast cancer. The guideline includes a recommendation for individuals who developed an isolated progression in the brain while on single-agent trastuzumab, to treat the brain metastasis and continue the single-agent trastuzumab. In a retrospective series of 80 individuals with brain metastases from breast cancer, the use of lapatinib and trastuzumab-based therapy significantly improved OS compared to chemotherapy or radiotherapy alone (Bartsch, 2012). Median OS was 13 months for those receiving trastuzumab with or without chemotherapy and at 24 months of follow-up, the median OS for lapatinib (with or without trastuzumab or chemotherapy) was not reached. A phase III randomized trial (GeparQuinto, GBG 44) enrolled individuals with untreated HER2positive, operable or locally advanced breast cancer randomized to treatment with lapatinib (ECH-TL group) versus trastuzumab (ECH-TH group) in combination with neoadjuvant anthracycline-taxane-based chemotherapy. There were improved rates of pathologic complete response in the ECH-TH group with 93 (30.3%) of 307 participants compared to 70 (22.7%) of 308 participants in the ECL-TL (odds ratio [OR] 0.68 [95% CI, 0.47-0.97]; p=0.04) (Untch, 2012). Baselga and colleagues reported results from NeoALTTO, an open-label, multicenter, phase III randomized trial of dual HER2 inhibition with lapatinib and trastuzumab versus lapatinib alone or trastuzumab alone in the neoadjuvant setting. Individuals received 6 weeks of the assigned biologic agent(s) followed by an additional 12 weeks of therapy in combination with paclitaxel prior to definitive breast surgery. A significantly higher (p=0.0001) pathologic complete response (pCR) was noted in the combination lapatinib and trastuzumab group (51.3%; 95% CI, 43.1-59.5) compared to the group treated with trastuzumab alone (29.5%; 22.4-37.5). Grade 3 and 4 adverse events were more frequent in the dual lapatinib and trastuzumab cohort (21.7%) compared to 1.3% in trastuzumab alone and 18.8% in the lapatinib group. Participants who were unable to complete the planned therapy due to side effects were higher in the groups treated with lapatinib alone (18.8%) and combination lapatinib and trastuzumab (39.5%) versus the trastuzumab alone group (8.1%). Additional long-term data and studies are needed to confirm dual inhibition of HER2 in the neoadjuvant setting is safe and effective. Event-free survival and overall survival were prespecified secondary endpoints in the phase III NeoALTTO trial. De Azambuja (2014a) and colleagues reported at an event follow-up of 3.77 years, there was no significant difference in event-free survival between the lapatinib and trastuzumab groups (HR 1.06, 95% CI, 0.66-1.69, p=0.81) and between the combination and trastuzumab groups (HR 0.78, 95% CI, 0.47-1.28, p=0.33). Similarly, there was no significant difference in the 3-year over-all survival 93% for lapatinib, 90% trastuzumab and 95% for combination therapy. However, the authors reported for the subset of participants that achieved pCR, the 3-year event free survival was significantly improved compared to those that did not achieve pCR (HR 0.38, 95% CI, 0.22-0.63, p=0.0003). Those that achieved pCR also had significantly improved overall survival when compared to those that did not achieve pCR (HR 0.35, 95% CI, 0.15-0.70, p=0.005). Clinical indications combining trastuzumab with lapatinib are a category 2A recommendation in the NCCN practice guidelines (2015) for individuals with HER2 overexpressing metastatic breast cancer that have received prior trastuzumab therapy. The CPG also notes the optimal neoadjuvant regimen for HER2-targeting remains uncertain. Gastric, Esophageal and Gastroesophageal Carcinoma – In October 2010, the FDA approved trastuzumab "in combination with cisplatin and capecitabine or 5-fluorouracil, for the treatment of individuals with HER2 overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma, who have not received prior treatment for metastatic disease." Treatment for gastric cancer may continue until disease progression (Product Information, 2015). Bang (2010) and colleagues reported results from ToGA (trastuzumab for gastric cancer) a multicenter, phase III randomized trial investigating trastuzumab as first-line treatment of locally advanced, recurrent or metastatic gastric and gastroesophageal adenocarcinoma. A total of 3807 individuals with gastric carcinoma were tested for HER2. Eligibility for inclusion in the study was HER2 positivity defined as IHC 3+ or FISH positive (defined as HER2: CEP17 ratio ≥2.0) (Bang, 2010). Of these, 594 individuals had HER2+ tumors and were randomized to a control group receiving chemotherapy or to a treatment group receiving chemotherapy plus trastuzumab. The median number of trastuzumab cycles was 8 (range 1-49). At 18.6 months of follow-up, the median OS was 13.5 months in the trastuzumab arm, compared to 11.1 months OS in the control group (p=0.0048) at a median follow-up of 17.1 months. The overall response rate (ORR) was also significantly improved for the trastuzumab group compared to controls, 47.3% vs. 34.5%, respectively. The NCCN practice guideline for gastric cancer (2015) and the National Cancer Institute PDQ® (2015) for gastric cancer list the use of trastuzumab as a part of combination therapy for HER2-positive advanced gastric, esophageal and gastroesophageal adenocarcinoma. In a Cochrane Review of chemotherapy for gastric cancer (Wagner, 2010), the authors recommended HER2 overexpression testing for all gastric cancers and use of trastuzumab in combination therapy with cisplatin and 5FU for HER2-positive gastric carcinomas.
