Evaluation of Lasofoxifene Combined With Abemaciclib Compared With Fulvestrant Combined With Abemaciclib in Locally Advanced or Metastatic ER+/HER2- Breast Cancer With an ESR1 Mutation
The goal of this clinical trial is to assess the efficacy, safety and tolerability of the combination of lasofoxifene and abemaciclib compared to fulvestrant and abemaciclib for the treatment of pre- and postmenopausal women and men who have previously received ribociclib or palbociclib-based treatment and have locally advanced or metastatic estrogen receptor positive (ER+)/human epidermal growth factor 2 negative (HER2-) breast cancer with an estrogen receptor 1 (ESR1) mutation. The main question the study aims to answer is: • To compare the efficacy of the combination of lasofoxifene and abemaciclib with that of fulvestrant and abemaciclib Participants will receive either receive 5 mg/d of oral lasofoxifene plus oral abemaciclib 150 mg twice a day or the combination of fulvestrant 500 mg intramuscular (IM) on Days 1, 15, and 29 and then once monthly thereafter plus oral abemaciclib 150 mg twice a day.

PAveMenT: Palbociclib and Avelumab in Metastatic AR+ Triple Negative Breast Cancer
This clinical study is aiming to determine the safest doses and schedule for the combination of two drugs named palbociclib and avelumab. The study will also be investigating how effective the combination is for a subgroup of breast cancer patients whose cancer expresses the androgen receptor (AR) but not the oestrogen (hormone) or HER2 receptors. Palbociclib is a drug used in routine care for hormone-receptor (HR) positive and HER2 negative advanced breast cancer, the most common subtype of breast cancer. It is possible that the combination of palbociclib and avelumab will be a more effective cancer treatment than each drug separately, but this is unknown and this study is needed to establish the best dosage and schedule of each drug as well as how effective the combination is.

Alpelisib/iNOS Inhibitor/Nab-paclitaxel in Patients With HER2 Negative Metaplastic Breast Cancer (MpBC)
This is a research study to test the safety and effectiveness of using the drug alpelisib together with chemotherapy (nab-paclitaxel) and a drug called L-NMMA in patients with HER2 negative metastatic or locally advanced metaplastic breast cancer, who have not responded to previous treatments. Participants in this study in addition to the standard care chemotherapy will also receive the drug alpelisib and L-NMMA. The therapies will be administered every 3 weeks (1 cycle) until disease progression, toxicity or until the participant withdraws from the study. The nab-paclitaxel chemotherapy will be administered intravenously on Day 1 of the 3 week cycles. Participants will take the drug alpelisib by mouth once daily at a dose determined by a safety study and the drug L-NMMA will be given intravenously on days 1 to 5 of the 3 week cycles.

Beamion BCGC-1: A Study to Find a Suitable Dose of Zongertinib Used Alone and in Combination With Other Treatments to Test Whether it Helps People With Different Types of HER2+ Cancer That Has Spread
This study is open to adults aged 18 years and older with different types of HER2+ cancer that has spread and cannot be removed by surgery. People can take part in this study if their tumours show HER2 aberrations and previous treatment was not successful. The purpose of this study is to find a suitable dose of zongertinib that people with different types of HER2+ cancer that has spread can tolerate best when taken together with trastuzumab deruxtecan (T-DXd), with trastuzumab emtansine (T-DM1), with trastuzumab and capecitabine, with zanidatamab, or with mFOLFOX6 (with or without trastuzumab). Another purpose is to check whether zongertinib alone and in combination with other treatments can make tumours shrink. Zongertinib inhibits HER2. HER2 causes cancer cells to grow. In this study, participants receive treatment in cycles. Study participants are treated with zongertinib alone or in combination with other treatments. This study has 2 parts. In Part 1, participants in different groups receive increasing doses of zongertinib. In Part 2, participants are put into different groups by chance. Each group receives a different dose of zongertinib. Every participant has an equal chance of being in each group. During the study, the participants visit the study site regularly. In this study, researchers want to find the highest dose of zongertinib that participants can tolerate when taken together with other treatments. To find this out, researchers look at certain severe health problems that a number of participants have. The doctors regularly check the size of the tumour with imaging methods (CT/MRI) during the study. The doctors also regularly check participants' health and take note of any unwanted effects.

Stereotactic Ablative Body Radiotherapy (SABR) With Maintenance of Systemic Therapy Versus Physicians' Choice of Systemic Therapy for Oligoprogressive ER-positive, Her-2 Negative Breast Cancer II
The goal of this clinical trial is to assess Stereotactic Ablative Radiotherapy (SABR) as a method to delay a change in systemic therapy in patients with oligoprogressive ER-positive, HER2-negative advanced breast cancer. The main question it aims to answer is to assess whether the addition of SABR to continuation of first line endocrine therapy and CDK 4/6 inhibitor (Arm A) to patients with oligoprogressive ER-positive, HER2-negative advanced breast cancer could have longer time to strategy failure (TSF) in comparison to physician choice of systemic treatment (Arm B) in patients who had progressed first line. The treatment strategy in Arm A is to maintain patients on current endocrine therapy and CDK 4/6 inhibitor, controlling localised progressing sites of disease with SABR. Treatment strategy in Arm B is to maintain disease control with physician's choice of systemic therapy alone.
