Phase 1/1B Study of DS-8201a in Combination With ATR Inhibition (AZD6738) in Advanced Solid Tumors With HER2 Expression (DASH Trial)
Summary: The dose escalation phase of this trial identifies the safety, side effects and best dose of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how col...
A Modular Phase I/IIa, Open-label, Multi-centre Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of Ascending Doses of AZD9574 as Monotherapy and in Combination With Anti-cancer Agents in Patients With Advanced Solid Malignancies (CERTIS1)
Summary: This study will assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of AZD9574 individually and in combination with anti-cancer agents in participants with advanced cancer that has recurred/progressed.
A Prospective Non-interventional Study (NIS) of Trastuzumab DeRuxtecan (T-DXd) for Adult Patients With Advanced HER2-pOsitive GaStric or GastroesoPhageal Junction (GEJ) AdEnocarcinoma Who Have Received a PrIor Trastuzumab-based Regimen, Accompanied by a Disease RegistrY of Patients Treated With Conventional Therapies in a Real-world Setting in Europe (PROSPERITY)
Summary: Trastuzumab deruxtecan (T-DXD) as monotherapy is indicated for the treatment of adult patients with advanced HER2-positive advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma who have received a prior trastuzumab-based regimen. This study will assess the effectiveness of T-DXd, patient demographic and clinical characteristics, and treatment patterns in patients with advanced HER2-po...
A Prospective, Non-interventional Study (NIS) With Trastuzumab Deruxtecan For Patients With HER2-low Expressing Unresectable and/or Metastatic Breast Cancer Accompanied By a Disease Registry of Patients Treated With Conventional Chemotherapy (DESTINY Breast Respond HER2-low Europe)
Summary: Trastuzumab deruxtecan (T-DXd) as monotherapy is indicated for the treatment of adult patients with unresectable or metastatic HER2-low breast cancer who have received prior chemotherapy in the metastatic setting or developed disease recurrence during or within 6 months of completing adjuvant chemotherapy.
A Phase II/III Study of Paclitaxel/Carboplatin Alone or Combined With Either Trastuzumab and Hyaluronidase-oysk (HERCEPTIN HYLECTA) or Pertuzumab, Trastuzumab, and Hyaluronidase-zzxf (PHESGO) in HER2 Positive, Stage I-IV Endometrial Serous Carcinoma or Carcinosarcoma
Summary: This phase III trial tests whether adding trastuzumab and hyaluronidase-oysk (Herceptin Hylecta \[TM\]) or pertuzumab, trastuzumab and hyaluronidase-zzxf (Phesgo \[TM\]) to the usual chemotherapy (paclitaxel and carboplatin) works to shrink tumors in patients with HER2 positive endometrial cancer. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to spe...
Phase 1b Study of Pidnarulex and Trastuzumab Deruxtecan in Patients With HER2 Expressing Solid Tumors
Summary: This phase I trial tests the safety, side effects, and best dose of pidnarulex in combination with trastuzumab deruxtecan in treating patients with breast cancer and other solid tumors that express varying levels of a protein called HER2 and that has spread from where it first started (primary site) to other places in the body (metastatic), that cannot be removed by surgery (unresectable), or that...
Optimizing Antibody-Drug Conjugate Therapy Through Molecular Analysis for Therapy Choice (ADC MATCH)
Optimizing Antibody-Drug Conjugate Therapy Through Molecular Analysis for Therapy Choice (ADC MATCH)
Summary: This phase II ADC MATCH screening and multi-sub-study treatment trial is evaluating whether biomarker-directed treatment with one of three antibody-drug conjugates (ADCs) (sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan) works in treating patients with solid tumor cancers that have high expression of the Trop-2, nectin-4, or HER2 proteins and that may have spread from where t...
A Phase I Study of DS-8201a in Combination With Olaparib in HER2-Expressing Malignancies
Summary: This phase I trial identifies the side effects and best dose of DS-8201a and olaparib in treating patients with HER2-expressing cancers that have spread to other places in the body or cannot be removed by surgery or ovarian cancer that remains despite treatment with a platinum treatment (platinum resistant). Olaparib is a drug that blocks an enzyme involved in many cell functions, including the re...
A Phase II Study of Induction Tucatinib and Trastuzumab With Total Neoadjuvant Therapy for Locally Advanced HER2-amplified Rectal Adenocarcinoma
Summary: The study researchers believe that a combination of the drugs trastuzumab and tucatinib, given with standard chemotherapy (capecitabine and oxaliplatin/FOLFOX), may help participants with rectal cancer.
A Phase III, Randomized, Multicenter, Open-label Study to Evaluate SHR-A1811 in Combination With Chemotherapy and Adebrelimab Versus Trastuzumab in Combination With Chemotherapy and Pembrolizumab in Patients With Previously Untreated, Unresectable, Locally Advanced or Metastatic, Gastric or Gastroesophageal Junction Adenocarcinoma Expressing
Summary: This study aims to evaluate the efficacy and safety of SHR-A1811 combined with chemotherapy and immune checkpoint inhibitor versus standard first-line therapy in gastric or gastroesophageal junction adenocarcinoma.
a Randomized Trial for OLIGo Metastases Breast cAncer With or Without Metastasis-dIrected Therapy
Summary: OLIGAMI trial is a multi-institutional, two-arm, open-label, randomized controlled phase III trial being conducted with the participation of 50 hospitals belonging to Japan Clinical Oncology Group. After the first registration, all patients will be performed in a 12-week, subtype-specific, systemic therapy consisting of CDK4/6 inhibitors with hormonal therapy for luminal BC, docetaxel with trastuz...
A Phase 3, Randomized, Open-label, Multicenter, Controlled Study to Evaluate the Efficacy and Safety of Zanidatamab in Combination With Physician's Choice Chemotherapy Compared to Trastuzumab in Combination With Physician's Choice Chemotherapy for the Treatment of Participants With Metastatic HER2-positive Breast Cancer Who Have Progressed on, or Are Intolerant to, Previous Trastuzumab Deruxtecan Treatment
Summary: The efficacy and safety of zanidatamab in combination with physician's choice of chemotherapy compared with trastuzumab in combination with physician's choice of chemotherapy will be evaluated for the treatment of participants with metastatic HER2-positive breast cancer who have progressed on, or are intolerant to, previous T-DXd treatment.
