Based on data that Cyclin D kinase (CDK) inhibitors reverse resistance to anti-androgens in prostate cancer cell lines, we hypothesize that the use of CDK inhibition may enhance the activity of anti-androgens in AR-positive TNBC. Methods: Key eligibility include: patients with centrally confirmed AR-positive TNBC, defined as AR expression >0%; 0 to 1 line of prior therapy for metastatic disease; and measurable disease. Patients are treated with bicalutamide 150mg orally once daily plus ribociclib at one of 3 dose levels (see table). Results: AR expression was positive by trial criteria in 74% of screened patients. Three patients have been accrued at each dose level. Median age is 56 and 6 and 3 patients were treated in first and second-line settings, respectively. Median AR expression was 50% (range 5 to 75%). Toxicity data is available for 6-patients treated on dose levels 1 and 2. No dose-limiting toxicities were noted. As anticipated with ribociclib, the most common toxicity is neutropenia (1 patient grade 4 and 2 patients grade 3). Two patients experienced grade 3 hypertension and 1 experienced grade 3 lymphopenia. Grade 2 or lower toxicities included fatigue, nausea, hyperglycemia and mucositis. One patient experienced grade 1 QT interval prolongation. Conclusion: The combination of bicalutamide and ribociclib is tolerable without unexpected toxicities. Data on the 3-patients treated at dose level 3 and dose expansion will be included. Phase 2 dosing schedule will be decided based on phase 1 results.

PCR rates over 80% have been described and achieving a pCR is associated with a favorable long-term outcome. In addition, achieving a radiologic complete response (rCR) is predictive of the pathologic response in HER2-positive tumors. Therefore it is hypothesized that image-guided evaluation based on the early occurrence of rCR can be used to tailor the number of chemotherapy cycles. Trial design This is a single arm, multicenter study evaluating the efficacy of image-guided de-escalation of neoadjuvant treatment with paclitaxel, Herceptin®, carboplatin, and pertuzumab (PTC-ptz). Radiologic evaluation with contrast-enhanced breast MRI and ultrasound of the axilla (in cN+ patients) is performed at baseline and after 3, 6, and 9 cycles of treatment. In case of rCR of the breast (and axilla) after 3 or 6 cycles, early surgery will be performed. If residual tumor is present after 3 and 6 cycles, patients will continue the PTC-ptz regimen to complete a total of 9 cycles. All patients will receive adjuvant Herceptin® and pertuzumab to complete 1 year of anti-HER2 blockade and endocrine treatment according to local guidelines if HR-positive. The study will be performed in the Netherlands in approximately 35 centers. Eligibility criteria Eligible patients have histologically proven stage II/III HER2-positive primary breast cancer with known hormone-receptor status. Patients must have a measurable breast tumor on baseline MRI and can be either node negative or node positive. Specific aims The aim is to evaluate the efficacy of image-guided de-escalation of neoadjuvant chemotherapy in HER2-positive breast cancer on event-free survival (EFS) at 3 years as primary endpoint. Secondary endpoints are overall survival, rCR, concordance between rCR and pCR (ypT0/is, ypN0), differences in EFS and OS following pCR between patients who received 3, 6, or 9 cycles, and toxicity. Statistical methods This is a single-arm, two stage study with one interim-analysis and a final analysis. Statistics will be performed for each hormone receptor subgroup separately. Stopping rules are based on 3-year EFS-rates described in literature (88% for HR-negative tumors and 90% for HR-positive tumors) and calculated using the exact conditional Poisson distribution. The study is successful with ≤34 EFS-events in the HR-negative subgroup and ≤38 events in the HR-positive subgroup after 700 patient-years of follow-up. The three-year EFS-estimate will be calculated using Kaplan-Meier statistics. Present accrual and target accrual Target accrual is 231 patients for the HR-negative group and 231 patients for the HR-positive group. Present accrual will follow.

D-0502 is an orally bioavailable SERD with potent activity in various HR+ and HER2- breast cancer cell lines and xenograft models. Its combination with palbociclib in both MCF-7 xenograft model and ESR-1 mutated (Y537S) patient derived breast cancer xenograft models resulted in further tumor growth inhibition or regression. Drug metabolism and pharmacokinetic studies both in vitro and in vivo demonstrated that D-0502 exhibits favorable PK profiles suitable for clinical development. Trial Design: D-0502 is currently being evaluated in a phase 1 trial of women with advanced or metastatic HR+, HER2- breast cancer (MBC) (NCT03471663). This is a multicenter, open-label phase I study of D-0502 single agent and D-0502 in combination with standard dose of palbociclib. The primary objective is to characterize the safety and tolerability of D-0502 and D-0502 in combination with palbociclib, to identify an MTD and/or RP2D. The secondary objective is to evaluate the PK properties and the preliminary anti-tumor activities. Patients will receive D-0502 orally every day and treatment will be administered as 28-day cycles. The study has two parts: Dose Escalation (phase 1a) and Dose Expansion and Combination (phase 1b). In phase Ia, patients will be enrolled using a conventional dose-escalation algorithm (3+3 subjects per dose level) with 4 sequential dose cohorts to identify the MTD and RDE (recommended dose for expansion) in phase 1b) which will be at or below MTD. In phase 1b, there will be 2 cohorts, one is D-0502 single agent administered at RDE and the other is D-0502 in combination with standard dose of palbociclib, each with approximately 12 patients. Key Eligibility Criteria: Eligible patients included women with confirmed HR+, HER2- MBC who have previously received no more than 2 prior chemotherapies for MBC; ECOG 0-1; evaluable (phase 1a) or measurable (phase 1b) disease (RECIST v1.1); premenopausal or postmenopausal status; adequate hematologic, hepatic and renal functions.

Combination therapy with checkpoint inhibition and chemotherapy is under investigation; preliminary research showed improved objective response rate (ORR) with combination therapy versus chemotherapy alone.1 Durvalumab is a selective, high-affinity, engineered, human monoclonal antibody that blocks programmed cell death-ligand 1 (PD-L1) binding to programmed cell death 1 (PD-1) and CD80 allowing T cells to recognize and kill tumor cells. This study is designed to assess the efficacy and safety of durvalumab + paclitaxel as 1L treatment in patients with mTNBC. Additionally, this study will also evaluate potential novel triplet treatment regimens of durvalumab + paclitaxel in combination with immune-modulating agents, selumetinib (ARRY-142886; AZD6244, an inhibitor of mitogen activated protein kinase/extracellular signal regulated kinase [MAPK/ERK]), danvatirsen (AZD9150, an antisense oligonucleotide designed to down-regulate expression of signal transducer and activator of transcription 3 protein), oleclumab (MEDI9447, an anti-CD73 monoclonal antibody), and capivasertib (AZD5363, a highly selective, oral, small molecule AKT inhibitor) that may provide further benefit to patients with mTNBC. Methods: BEGONIA is a phase Ib/II, open-label, multicenter, platform study (EudraCT No: 2018-000764-29) consisting of 2 parts: Part 1 is a phase Ib study planned to be conducted in approximately 100 patients (20 per arm) to assess the safety and tolerability of durvalumab (1500 mg intravenous [IV], q4w) + paclitaxel (90 mg/m2 IV, 4 week cycle, 3 weeks once weekly [days 1, 8, 15], 1 week off) (arm 1); and durvalumab + paclitaxel in combination with selumetinib (arm 2), danvatirsen (arm 3), oleclumab (arm 4) and capivasertib (arm 5) until disease progression. Dosing of the immune-modulating agents will be based on the previously defined recommended phase 2 doses of the component doublets (where available) in combination with durvalumab + paclitaxel using a rolling 6-patient design to evaluate for toxicity. Part 2 is a phase II study planned to be conducted in approximately 150 to 225 patients to evaluate efficacy of up to 2 best triplet combination arms based on their safety and efficacy outcomes in Part 1. The primary objective of Part 1 is safety and of Part 2 is efficacy (primary endpoint: progression free survival [PFS]); additionally, efficacy will be assessed in both parts, including overall survival, ORR, PFS, and duration of response (RECIST 1.1).

Because TNBC does not currently have specific targeted agents approved for use in the early setting it is treated primarily with chemotherapy. A growing body of evidence indicates that TNBC is more immunogenic than other subtypes of breast cancer and promising clinical activity has been reported with atezolizumab (an anti–PD-L1 antibody) in Phase 1/1b metastatic TNBC trials. Furthermore, the anti-tumor activity of PD-1/PD-L1 targeting drugs is hypothesized to be enhanced when co-administered with chemotherapy. ALEXANDRA/IMpassion030 will evaluate the efficacy and safety of atezolizumab in combination with standard adjuvant chemotherapy in early TNBC. Methods: ALEXANDRA/IMpassion030 is a global, prospective, randomised, open-label Phase 3 trial investigating the efficacy, safety and pharmacokinetic (PK) profile of adjuvant atezolizumab plus standard chemotherapy versus chemotherapy alone in early TNBC. In total, 2300 patients diagnosed with non-metastatic operable stage II or III TNBC confirmed by central pathology review will be randomised. TumorPD-L1evaluationwill be performed centrally. Patients will be stratified by type of surgery, nodal status, and PD-L1 status. The adjuvant treatment will consist of weekly paclitaxel 80 mg/m2 for 12 weeks followed by dose dense anthracycline (epirubicin 90 mg/m2 or doxorubicin 60 mg/m2) and cyclophosphamide 600 mg/m2 for 4 doses every 2 weeks or the same chemotherapy regimen (T-EC/AC) given concomitantly with atezolizumab 840 mg every 2 weeks followed by maintenance atezolizumab 1200 mg every 3 weeks until completion of 1 year of atezolizumab.

In the year 2017, based on the results of MONALEESA-2, ribociclib in combination with an aromatase inhibitor (AI) was approved for the treatment of HR+, HER2– aBC in postmenopausal women with no prior therapy for their advanced disease (first-line treatment). Beyond phase 3 trials, further data for ribociclib are now becoming available from the phase 3b trials, RIBECCA and COMPLEEMENT-1, involving approximately 500 and 3000 patients with aBC, respectively. However, real-world evidence for the effectiveness, safety, and tolerability of ribociclib + AI in the routine clinical practice is needed to further support the use of this combination in the first-line therapy. Methods: RIBANNA is a non-interventional study, which started in October 2017 and plans to enroll 3020 patients across ˜400 sites in Germany. Postmenopausal women diagnosed with aBC will be enrolled into 3 cohorts (cohort 1: ribociclib + AI; cohort 2: endocrine monotherapy; and cohort 3: chemotherapy). Across all cohorts, patients will be treated in accordance with the respective German-prescribing guidelines. Data related to efficacy (with PFS as the primary efficacy criterion), safety, tolerability, duration of therapy, and impact on quality of life (QoL) will be collected. QoL will be assessed using the validated patient questionnaires. This study was especially designed to analyze the patient data from sequential lines of therapy in all three cohorts over a period of up to 7 years. For this purpose, RIBANNA will collect the data on each line of treatment and the reason for changing treatment in all 3 cohorts. The same accounts for QoL, which will also be assessed periodically, regardless of disease progression and initiation of subsequent therapies. RIBANNA is the first study to provide the real-world evidence regarding treatment of HR+, HER2− aBC with the CDK4/6 inhibitor, ribociclib. This study includes 3 treatment cohorts (ribociclib + AI, endocrine monotherapy, and chemotherapy) with subsequent treatment algorithms and assessment of QoL over the entire study period.
