participants with metastatic breast cancer.\n\nThe main questions it aims to answer are:\n\n* What is the optimal biological dose (OBD) of efti in combination with weekly paclitaxel chemotherapy?\n* Can efti combined with weekly paclitaxel chemotherapy prolong overall survival in participants with metastatic breast cancer if compared to weekly paclitaxel chemotherapy alone?\n\nIn the first component of the trial (phase 2, lead-in) researchers will compare two groups (different dose levels of efti in combination with standard chemotherapy) to see if the treatment is safe and well tolerated and evaluate which is the optimal biological dose. In the second component of the trial (phase 3) researchers will assess if the treatment of metastatic breast cancer with the optimal biological dose of efti in combination with paclitaxel is superior compared to chemotherapy alone (placebo-controlled).\n\nThe treatment concept of each trial component consists of a chemo-immunotherapy phase followed by an immunotherapy phase. In the first phase participants will be treated with efti plus paclitaxel chemotherapy or placebo plus paclitaxel chemotherapy. After completion of the chemotherapy per standard of care, participants will be treated with the study agent alone.', 'detailedDescription': 'The AIPAC-003 trial consists of an open-label dose optimization lead-in component followed by a double-blinded, randomized, placebo-controlled phase 3 component.\n\nThe main objectives of the dose optimization lead-in (phase 2) are to evaluate and compare the safety and tolerability of 2 different dose levels of efti (30 mg and 90 mg) combined with paclitaxel, and to define the optimal biological dose (OBD) of efti in combination with weekly paclitaxel for the phase 3 part of the trial. Recruitment to the dose-optimization lead-in will be considered complete when 29 participants per cohort are randomized and considered evaluable for OBD analysis.\n\nThe main objective of the phase 3 is to demonstrate that overall survival (OS) is superior in participants treated with efti combined with weekly paclitaxel compared to weekly paclitaxel plus placebo. Approximately 771 participants will be randomized 2:1 to Arm A (active arm): paclitaxel + efti at OBD and Arm B (control arm): paclitaxel + placebo. The exact patient population will be defined after determination of the OBD.\n\nThe duration of the trial will be approximately 24 months for the dose optimization lead-in component and 60 months for the phase 3 component. The phase 3 will start prior to the completion of the phase 2 (once the OBD has been defined).\n\nIt is planned to conduct the trial at up to 20 sites in up to 4 countries across North America and Europe for the lead-in and at up to 150 sites in up to 25 countries across North America, Europe, Latin America and the Asian Pacific region for the phase 3.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Metastatic HR+ positive (estrogen receptor positive and/or progesterone receptor positive) or hormone receptor negative (HR˗), and HER2-neg breast adenocarcinoma, histologically proven by biopsy on the last available tumor tissue\n* Participants with HR+ metastatic breast cancer (MBC) who progressed on or after ≥1 line of endocrine based therapy and are indicated to receive chemotherapy for metastatic disease\n* Participants with HR- MBC (i.e. triple-negative breast cancer \\[TNBC\\]) who are indicated to receive paclitaxel chemotherapy without PD 1/PD-L1 therapy in the 1st line setting for metastatic disease\n* ECOG performance status 0-1\n* Expected survival longer than three months\n\nExclusion Criteria:\n\n* Prior chemotherapy for metastatic breast adenocarcinoma\n* Participants with HR+ MBC who have received \\<1 line of ET based therapy in the metastatic setting\n* Participants with HR+ MBC who are not primary or secondary resistant to ET-based therapy and would be candidates to ET based therapy as per applicable treatment guidelines\n* TNBC participants who are candidates for PD-1/PD-L1 therapy in combination with chemotherapy\n* Disease-free interval of less than twelve months from the last dose of adjuvant chemotherapy'}, 'identificationModule': {'nctId': 'NCT05747794', 'acronym': 'AIPAC-003', 'briefTitle': 'Study in Metastatic Breast Cancer Patients Receiving Eftilagimod Alpha or Placebo in Combination with Paclitaxel Chemotherapy', 'organization': {'class': 'INDUSTRY', 'fullName': 'Immutep S.A.S.'}, 'officialTitle': 'AIPAC-003 (Active Immunotherapy and PAClitaxel): a Randomized, Double-blind, Placebo-controlled Phase 3 Trial Testing Eftilagimod Alpha (soluble LAG-3) in HER2-neg/low Metastatic Breast Cancer Patients Receiving Paclitaxel, Following an Open-label Dose Optimization', 'orgStudyIdInfo': {'id': 'AIPAC-003'}, 'secondaryIdInfos': [{'id': '2022-003323-17', 'type': 'EUDRACT_NUMBER'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'open label lead-in (phase 2): eftilagimod alpha 30mg + paclitaxel', 'description': 'eftilagimod alpha 30mg s.c. + 80mg/m\\^2 paclitaxel i.v.
