There are about 3194 clinical studies being (or have been) conducted in Portugal. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
HR+/HER2-negative BC represent ∼70% of all newly diagnosed breast tumours and are responsible for most recurrences and deaths due to this disease, and despite available standard therapies, ∼15-20% of hormone tumours recur at distant sites. As BC is a clinically and biologically heterogeneous disease, intrincsic subtype may play an important role in classifying patients. In this case, HER2-E subtype is present in approximately 6.6-11.0% of HR+/HER2-negative tumors and might express either HER2, estrogen receptor (ER) or progesterone receptor (PR), we also know that HER2-E is present twice as much in metastatic tumors compared to primary tumors and that HER2-E patients may benefit in terms of PFS form an anti-HER2 drug as was showed using retrospective sample in EGF30008 trial. Therefore, incorporation of novel drugs in combination with endocrine therapy (ET) can improve patient outcomes in HR+/HER2-negative BC advanced disease specially in those with HER2-E subtype. Methods NEREA is an open-label, single arm, multicenter phase II study evaluating treatment with neratinib in combination with ET in pre and post-menopausal women and men with locally advanced or metastatic HER2-enriched (HER2-E), HR+/HER2-negative breast cancer who had recurrence or progression while receiving previous ET (either aromatase inhibitors, tamoxifen or fulvestrant) in the adjuvant setting or to treat advanced disease or both. The study will follow a Simon's 2-stage design with one interim and one final efficacy analysis. The primary objective will is assess the efficacy of neratinib in combination with ET is this group of patients, efficacy will be measured as Progression-Free Survival at 6 months (PFS6) defined as the proportion of patients alive and without progression, locally assessed by the investigator through the use of RECIST v.1.1 at 24 weeks after first treatment administration, imaging evaluation will be performed every 8 weeks for the first 12 months following treatment start, and every 12 weeks thereafter. Secondary endpoints include Clinical Benefit Rate at 6 months , Overall Response rate, Duration of response, Time to response and Incidence, duration and severity of Adverse Events. The interim analysis will be conducted when 33 patients are evaluable for the primary endpoint having the potential for at least 3 'on treatment' disease assessment scans. If less than 15 patients achieved a PFS6, the trial will be terminated for futility in favor of the null hypothesis. If more than 28 patients achieved a PFS6, the trial will be stopped in favor of the alternative hypothesis demonstrating activity. If none of the two above-mentioned conditions are attain, up to a further 23 patients may be evaluated, for at least a total of 56 evaluable patients. Therefore, if a total of 28 or more patients achieved a PFS6 at the end of the second stage, then the null will be rejected in favor of the alternative. Eligible patients will receive neratinib 240 mg every day in combination with ET, with either exemestane, fulvestrant or tamoxifen: exemestane 25 mg every day orally, tamoxifen 20mg every day orally or fulvestrant 500 mg administered in two intramuscular injections of 250 mg each at C1D15 and at D1 of each subsequent 28-day cycle at investigator discretion. LHRH agonist will be used in men and premenopausal women if no oophorectomy has been performed previously. All patients will take prophylactic loperamide with a stablished doses scheme during the firs cycle and on demand in subsequent cycles
This is a randomized, double-blind, placebo-controlled, multicenter, 28-day study of adult participants hospitalized with COVID-19, with a safety follow-up telephone call at Day 60.
The main purpose of this study is to compare the efficacy of bempegaldesleukin plus nivolumab versus nivolumab in patients with completely resected Stage IIIA/B/C/D, or Stage IV cutaneous melanoma who are at high risk for recurrence.
This is an open-label, multicenter, rollover study to evaluate the safety, tolerability, and efficacy of long-term administration of open-label gantenerumab in participants with AD who completed Study WN29922 or WN39658, either the double-blind or open-label extension (OLE) part.
The study is to evaluate the efficacy and safety of evobrutinib administered orally twice daily versus Teriflunomide (Aubagio®), administered orally once daily in participants with Relapsing Multiple Sclerosis (RMS). Participants who complete the double-blind treatment period (DBTP) and double-blind extension period (DBEP) prior to approval of a separate long-term follow-up study in their country will get an option for evobrutinib treatment continuation through a 96-week open-label extension (OLE) period.
The primary objective of this study is to evaluate the efficacy of magrolimab in combination with azacitidine compared to that of azacitidine plus placebo in previously untreated participants with intermediate/high/very high risk myelodysplastic syndrome (MDS) by Revised International Prognostic Scoring System (IPSS-R) as measured by complete remission (CR) and overall survival (OS).
The purpose of the study is to evaluate the effect of macitentan 75 mg versus placebo on exercise capacity at Week 28 in participants with chronic thromboembolic pulmonary hypertension (CTEPH).
The purpose of this study is to evaluate the safety and effectiveness of empirical posterior wall isolation (PWI), left atrial appendage electrical isolation (LAAEI) and coronary sinus isolation (CSI) when compared to pulmonary vein isolation (PVI) alone: - PVI alone, - PVI + PWI, - PVI + PWI + LAAEI, - PVI + PWI + LAAEI + CSI.
The purpose of this trial is to evaluate the efficacy and safety of subcutaneous secukinumab 300 mg compared to placebo, in combination with standard of care therapy (SoC), in subjects with active lupus nephritis (ISN/RPS Class III or IV, with or without co-existing class V features).
The purpose of study is to evaluate if the addition of GSK3359609 to pembrolizumab as first-line treatment improves the efficacy of pembrolizumab in participants with recurrent or metastatic (R/M) head and neck squamous cell carcinoma/cancer (HNSCC).This is a randomized, double-blind, adaptive Phase II/III study comparing a combination of GSK3359609 inducible T cell co-stimulatory receptor (ICOS) agonist and pembrolizumab to pembrolizumab plus placebo in participants with programmed death receptor 1-ligand 1 (PD-L1) combined positive score (CPS) >=1 R/M HNSCC.
