SAN ANTONIO – After a 2-year follow-up, the efficacy and cardiac toxicity profile between CT-P6, a trastuzumab biosimilar candidate, and trastuzumab as neoadjuvant and then adjuvant therapy for patients with early HER2-positive breast cancer remains consistent with previous results.

Similarity in safety and efficacy at 1 year was previously demonstrated in the phase 3 trial, as well as similarity in cardiac toxicity at a median of 19 months. Updated disease-free survival, overall survival, and cardiac toxicity with a median follow-up of 2 years will be presented by Francisco J. Esteva, MD, PhD, of the Laura & Isaac Perlmutter Cancer Center at NYU Langone Health, New York, in a poster presentation at the San Antonio Breast Cancer Symposium.

For the trial, 549 patients with HER2-positive early breast cancer were randomized to receive CT-P6 (n = 271) or trastuzumab (n = 278) in combination with docetaxel (cycles 1-4) and 5-fluorouracil, epirubicin, and cyclophosphamide (cycles 5-8). CT-P6 or trastuzumab was administered at 8 mg/kg (cycle 1 only) followed by 6 mg/kg every 3 weeks. After surgery, patients received CT-P6 or trastuzumab monotherapy and then entered the follow-up period.

A total of 528 patients entered the follow-up period, with a median duration of 27 months. Disease-free and overall survival were similar in the two arms in both the per-protocol set and the intention-to-treat set. In the intention-to-treat set, the 2-year disease-free survival was 86% (95% confidence interval, 80%-90%) in the CT-P6 arm and 90% (95% CI, 85%-93%) in the trastuzumab arm. Two-year overall survival was 97% (95% CI, 93%-98%) in the CT-P6 arm and 98% (95% CI, 96%-99%) in the trastuzumab arm. Median disease-free and overall survival have not been reached, according to the abstract.

No new cases of heart failure were reported during the follow-up period. Left ventricular ejection fraction was similar in both arms. The efficacy and cardiac toxicity profile between CT-P6 and trastuzumab were consistent with published data.

“CT-P6 was consistently well tolerated with a similar cardiotoxicity profile to that of trastuzumab through a long duration of follow-up,” Dr. Esteva and authors said.

The study sponsor is Celltrion, maker of CT-P6. Dr. Esteva disclosed a consulting or advisory role with Celltrion, as well as relationships with various other pharmaceutical companies.

While the majority of the presentations at this year’s San Antonio Breast Cancer Symposium, to be held Dec. 4-8, will focus on treatments, a few will focus on the treatment decisions. One such presentation will report on the findings of the phase 3 STIC CTC trial. This trial seeks to determine if circulating tumor cells (CTC) could serve as a tool to choose between first-line hormone therapy and chemotherapy for ER-positive HER2-negative metastatic breast cancer.

In the standard arm of the trial, treatment was decided by clinicians, taking into account the criteria usually used in this setting. In the CTC arm, the type of treatment was decided by CTC count: Hormone-therapy was chosen if there were fewer than 5 CTC/7.5 mL (CellSearch technique) or chemotherapy if there were 5 or more CTC/7.5 mL. The main objective was to demonstrate the noninferiority of the CTC-based strategy for progression-free survival. The secondary clinical objectives of the French trial were to compare toxicity, quality of life, and overall survival between the two arms. The cost per progression-free life-years gained will be compared in the two arms, as well.

The results and analysis of STIC CTC will be presented by Francois-Clement Bidard, MD, PhD, of Institut Curie, Paris, and the University of Versailles (France), on Thursday, Dec. 6 at 11 a.m. CST.

Revisiting the old and enhancing with the new might describe the range of results in HER2+ breast cancer studies to be presented at the upcoming San Antonio Breast Cancer Symposium, which will be held Dec. 4-8 in San Antonio.

Since 2005, 12 months of trastuzumab added to chemotherapy alone has been the standard of care in patients with HER2-positive early breast cancer. PHARE (Protocol for Herceptin as Adjuvant Therapy With Reduced Exposure) was the first trial evaluating a reduced schedule of trastuzumab, a noninferiority trial comparing 6 with 12 months of adjuvant trastuzumab. Results published in 2013 in Lancet Oncology demonstrated a failure to prove that 6 months of treatment was non-inferior to 12 months. The final analysis of PHARE will be presented on Wednesday at SABCS 2018 by Xavier Pivot, MD, PhD, of Paul-Strauss Cancer Centre, Université de Strasbourg (France).

In a more recent study, trastuzumab emtansine (T-DM1) was pitted against trastuzumab as adjuvant therapy in patients with HER2-positive early breast cancer with residual invasive disease after neoadjuvant chemotherapy and HER2-targeted therapy including trastuzumab. The primary results of the phase 3 study (KATHERINE) will be presented by Charles E. Geyer, MD, of Virginia Commonwealth University and the Massey Cancer Center, both in Richmond.

As for the new, KATE2 is a phase 2 randomized trial evaluating the addition of checkpoint inhibitor atezolizumab to T-DM1 for patients with locally advanced or metastatic HER2-positive breast cancer who received prior trastuzumab and taxane-based therapy. Results will be presented by Leisha A. Emens, MD, PhD, professor at the University of Pittsburgh and director of translational immunotherapy for the Women’s Cancer Research Center there.

The Food and Drug Administration has granted a second “tissue-agnostic” approval for the treatment of cancer, this time to larotrectinib for adult and pediatric patients with solid tumors that harbor a genetic aberration known as an neurotrophic receptor tyrosine kinase (NTRK) fusion.

Specifically, the oral inhibitor of tropomyosin receptor kinase is approved for patients with solid tumors that have a NTRK gene fusion without a known acquired resistance mutation and have metastatic disease, are likely to experience severe morbidity from surgical resection, have no satisfactory alternative treatments, or have cancer that has progressed following treatment, the FDA said in a press release.

NTRK fusions are found in both children and adults with dozens of different cancer types. The genetic aberration tends to be rare in common cancers and nearly universal in certain uncommon cancers.

Approval of larotrectinib (Vitrakvi) was based on overall response rate and response duration in the first 55 patients with unresectable or metastatic solid tumors harboring an NTRK gene fusion enrolled across three multicenter, open-label, single-arm clinical trials. The ORR was 75% (95% confidence interval, 61%-85%), including 22% complete responses and 53% partial responses. At the time of database lock, median duration of response had not been reached, the FDA said.

The most common tumors were salivary gland tumors (22%), soft tissue sarcomas (20%), infantile fibrosarcomas (13%), and thyroid cancers (9%). Identification of positive NTRK gene fusion status was prospectively determined in local laboratories using next-generation sequencing or fluorescence in situ hybridization.

Results of the three trials, a phase 1 trial among 8 adult patients (LOXO-TRK-14001), a phase 1/2 trial among 12 pediatric patients (SCOUT), and a phase 2 basket trial among 35 adult and adolescent patients (NAVIGATE), were presented at the annual meeting of the American Society of Clinical Oncology in 2017.

The safety of larotrectinib was evaluated in 176 patients enrolled across the three clinical trials, including 44 pediatric patients. The most common adverse reactions with larotrectinib were fatigue, nausea, dizziness, vomiting, increased AST, cough, increased ALT, constipation, and diarrhea, the FDA said.

The recommended larotrectinib doses are 100 mg orally twice daily for adults and 100 mg/m² orally twice daily (maximum of 100 mg per dose) for pediatric patients.

The approval of larotrectinib follows the approval of pembrolizumab for certain solid tumors with the MSI-H biomarker, as the first approval for the treatment of cancer based on a biomarker rather than the particular body part or organ system affected by the tumor.

The FDA granted the accelerated approval of Vitrakvi to Loxo Oncology and Bayer.

Investigators presented results of the phase 3 IMpassion130 earlier this year demonstrating, for the first time, that a combination of an immune checkpoint inhibitor and a taxane provided significant clinical benefit to patients with advanced triple-negative breast cancer. However, the benefit was seen only in patients positive for programmed death-ligand 1 (PD-L1), the investigators reported at the annual congress of the European Society for Medical Oncology.

In the trial, 902 patients with untreated metastatic triple-negative breast cancer (mTNBC) were randomly assigned to receive the PD-L1 inhibitor atezolizumab (Tecentriq) plus nanoparticle albumin-bound (nab)–paclitaxel or placebo plus nab-paclitaxel. In an interim analysis, although there was no significant difference in median overall survival among all participants, atezolizumab was associated with a 38% improvement in median overall survival among patients with PD-L1–positive disease.

Additional analyses of the efficacy within immune biomarker subgroups in IMpassion130, including efficacy by BRCA status, will be presented at the upcoming 2018 San Antonio Breast Cancer Symposium, to be held Dec. 4-8 in San Antonio.

Leisha A. Emens, MD, PhD, professor of medicine in hematology/oncology, co-leader of the Hillman Cancer Immunology and Immunotherapy Program, and director of translational immunotherapy for the Women’s Cancer Research Center at the University of Pittsburgh Medical Center, will present the additional analyses on Wednesday, Dec. 5th at 9:30 a.m. CST.

The Food and Drug Administration has granted accelerated approval to lorlatinib for patients with anaplastic lymphoma kinase (ALK)–positive metastatic non–small cell lung cancer (NSCLC) whose disease has progressed on crizotinib and at least one other ALK inhibitor for metastatic disease or whose disease has progressed on alectinib or ceritinib as the first ALK inhibitor therapy for metastatic disease.

Approval of the next-generation ALK inhibitor was based on an overall response rate of 48% – with 4% complete and 44% partial – in a subgroup of 215 patients with ALK-positive metastatic NSCLC enrolled in a nonrandomized, phase 2 trial, the FDA said in a press announcement. All patients had been previously treated with one or more ALK kinase inhibitors.

The median response duration was 12.5 months (95% confidence interval, 8.4-23.7) and the intracranial overall response rate in 89 patients with measurable lesions in the CNS was 60% (95% CI, 49-70) with 21% complete and 38% partial responses.

Common adverse reactions in patients receiving lorlatinib were edema, peripheral neuropathy, cognitive effects, dyspnea, fatigue, weight gain, arthralgia, mood effects, and diarrhea. The most common laboratory abnormalities were hypercholesterolemia and hypertriglyceridemia, the FDA said.

The recommended dose of lorlatinib, to be marketed as Lorbrena by Pfizer, is 100 mg orally once daily.

The median response duration was 12.5 months (95% confidence interval, 8.4-23.7) and the intracranial overall response rate in 89 patients with measurable lesions in the CNS was 60% (95% CI, 49-70) with 21% complete and 38% partial responses.

Common adverse reactions in patients receiving lorlatinib were edema, peripheral neuropathy, cognitive effects, dyspnea, fatigue, weight gain, arthralgia, mood effects, and diarrhea. The most common laboratory abnormalities were hypercholesterolemia and hypertriglyceridemia, the FDA said.

The recommended dose of lorlatinib, to be marketed as Lorbrena by Pfizer, is 100 mg orally once daily.

The Food and Drug Administration has approved talazoparib, a poly (ADP-ribose) polymerase (PARP) inhibitor, for patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), HER2-negative locally advanced or metastatic breast cancer.

The FDA also approved BRACAnalysis CDx from Myriad Genetic Laboratories as the companion diagnostic to identify patients with deleterious or suspected deleterious gBRCAm who are eligible for talazoparib, the agency announced.

Approval was based on improved progression-free survival in EMBRACA, a phase 3, open-label trial of 431 patients with gBRCAm HER2-negative locally advanced or metastatic breast cancer. Patients in the trial were randomized 2:1 to receive either talazoparib (1 mg) or a physician’s choice of chemotherapy (capecitabine, eribulin, gemcitabine, or vinorelbine). All patients had received treatment with an anthracycline and/or a taxane previously.

Median progression-free survival was 8.6 months in the talazoparib arm, compared with 5.6 months in the chemotherapy arm (HR, 0.54; 95% CI, 0.41-0.71; P less than .0001).

Anemia was the most common hematologic adverse event, with grade 3 or greater occurring in 39.2% of patients on the PARP inhibitor, compared with 4.8% of patients treated with other agents, according to results of the trial presented at the 2017 San Antonio Breast Cancer Symposium.


Warnings and precautions for myelodysplastic syndrome/acute myeloid leukemia, myelosuppression, and embryo-fetal toxicity are included in the drug’s prescribing information. The PARP inhibitor’s most common adverse reactions of any grade are fatigue, anemia, nausea, neutropenia, headache, thrombocytopenia, vomiting, alopecia, diarrhea, and decreased appetite, the FDA said.

The recommended dose for talazoparib, marketed as Talzenna by Pfizer, is 1 mg taken as a single oral daily dose, with or without food.

Results of the phase 3 KEYNOTE-048 trial investigating pembrolizumab (Keytruda) for first-line treatment of recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) will be presented during a presidential symposium at the European Society for Medical Oncology Congress.

The drug is currently approved for second-line treatment of HNSCC. Merck, the maker of the anti–programmed cell death protein therapy, announced in July that the primary endpoint of overall survival as monotherapy in the first-line setting of advanced HNSCC had been met in patients whose tumors expressed programmed death–ligand 1.

More than 800 patients in KEYNOTE-048 were randomized to receive pembrolizumab as monotherapy or in combination with cisplatin or carboplatin and 5-FU, or cetuximab plus cisplatin or carboplatin and 5-FU.

The dual primary endpoints were overall survival and progression-free survival. The secondary endpoints of the study were PFS (at 6 months and 12 months), objective response rate, and time to deterioration in Quality of Life Global Health Status/Quality of Life Scales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, according to the company.

Further details from the interim analysis of KEYNOTE-048 will be presented by Barbara Burtness, MD, of Yale Cancer Center, New Haven, Conn., during Presidential Symposium 3 at ESMO 2018 on Oct. 22 in Munich.

An updated analysis of interim results for JAVELIN Renal 101 will be presented at a Presidential Symposium during the annual congress of the European Society for Medical Oncology (ESMO 2018), to be held Oct. 19-23 in Munich.

The phase 3 trial compared avelumab (Bavencio) in combination with axitinib (Inlyta) to sunitinib monotherapy as first-line treatment, in patients with advanced renal cell carcinoma (RCC). Interim analysis results announced by the company in a September press release indicated the combination of immunotherapy and a tyrosine kinase inhibitor showed “a statistically significant improvement in progression-free survival by central review for patients treated with the combination whose tumors had programmed death ligand-1‒positive (PD-L1+) expression greater than 1% (primary objective), as well as in the entire study population regardless of PD-L1 tumor expression (secondary objective).”

An updated analysis of progression-free survival and overall response rates will be presented at ESMO 2018 by Robert J. Motzer, MD of Memorial Sloan Kettering Cancer Center, New York.

A phase 1b study (JAVELIN Renal 100), published in Lancet Oncology, found the safety profile of the combination to be similar to either drug alone.

For the phase 3 trial, more than 800 patients with advanced RCC were randomized to first-line treatment with the combination of avelumab (10 mg/kg IV every 2 weeks) plus axitinib (5 mg orally, twice daily) or monotherapy with sunitinib (50 mg orally once daily, 4 weeks on/2 weeks off). The overall survival results will be presented at the Presidential Symposium 2 on Oct. 21.

This article was updated on 10/15/18 to reflect the fact that interim results will be presented.
