NCT07124403
Fluoropyrimidine drugs (5-Fluorouracil or 5-FU and its prodrug capecitabine) are a widely used in the treatment of numerous solid tumors in adults. Approximately 85% of administered 5-FU is rapidly catabolized in the liver into inactive dihydrofluorouracil (5-FUH2) by dihydro-pyrimidine dehydrogenase (DPD), leaving only a small fraction of the initial drug for an eventual transformation into cytotoxic metabolites. Impeded DPD activity is associated to an increase of cytotoxic metabolites leading to potentially very severe toxicities. To prevent these toxicities, a pre-therapeutic measurement of plasma uracil can help assess DPD activity. Indeed, uracil is an endogenous substrate of DPD and an increase in its plasma concentration may be associated with a decrease in DPD activity. In this case, a reduction of the fluoropyrimidine dose is suggested. However, the investigators observed that uracilemia increased concomitantly to the severity of renal impairment. There are two possible explanations for this observation. Either the renal impairment reduces the renal elimination of uracil from blood, or DPD activity is actually impaired. In both cases, this can explain an increase in plasma uracil concentration. However, the impact on fluoropyrimidine dosage is different in the two cases. If the increase in uracilemia is due to renal impairment, DPD activity remains unaffected and there is no need to reduce the fluoropyrimidine dose. If DPD activity is actually impaired, a reduction in the fluoropyrimidine dose is required. In cases of renal impairment, uracilemia may therefore not be as relevant for DPD assessment as in the absence of renal impairment. To assess if DPD activity is actually impede during renal impairment, the DPD activity of Peripheral Blood Mononuclear Cells (PBMCs) will be assessed together with uracilemia in patients with or without renal impairment. As uracilemia decreases after dialysis, the DPD activity of Peripheral Blood Mononuclear Cells (PBMCs) will also be assessed in patient before and after dialysis. Four groups of 50 patients will be studied: patients with normal renal function with hyperuracilemia (uracilemia ≥ 16 ng/mL) or normal uracilemia (uracilemia \< 16 ng/mL) ; and patients with renal impairment with hyperuracilemia (uracilemia ≥ 16 ng/mL) or normal uracilemia (uracilemia \< 16 ng/mL). The main objective of the study is to describe the distribution of DPD activity in these four populations. The secondary objectives are to determine in normorenal patients the optimal threshold for DPD activity in non-deficient patients, allowing differentiation between deficient and non-deficient patients based on uracilemia ; and to describe in patients with impaired renal function the distribution of uracilemia with respect to the threshold previously described with the aim of verifying the relevance of uracilemia as a marker of DPD activity in such patients.
NCT07178730
TNBC is a heterogeneous disease with distinct pathological, genetic, and clinical features among subtypes. Treatment results for high-risk primary TNBC remain poor compared to other breast cancer subtypes. Preoperative chemotherapy is the standard of care for patients with stage II or III primary TNBC. Multiple lines of clinical evidence demonstrate that TNBC patients who achieve a pCR to NACT, (ypT0/is ypN0), have an excellent long-term prognosis. A meta-analysis of individual patient data confirmed a strong association of pCR after NACT with improved long-term event-free survival (EFS, hazard ratio \[HR\] 0.24) and overall survival (OS, HR 0.16) benefit. Taxane- and anthracycline-based neoadjuvant regimens generally result in pCR rates between 25-50% \[REFs\], whereas the addition of platinum increases pCR rates to approximately 50-55%. The KEYNOTE-522 trial has demonstrated that the addition of the immune-checkpoint inhibitor PEM to anthracycline- (AC), taxane- and platinum-based NACT resulted in a significant increase in pCR rates to nearly 65%, associated with a significant reduction of recurrences (EFS, HR 0.65 at 5 years) and improvement of OS (HR 0.66). Based on these results, the KEYNOTE-522 regimen has been approved by the FDA and EMA and has become the standard of care for patients with stage II or III TNBC. Despite this significant progress, two major questions remain unresolved which will be investigated in the ADAPT-TN-IV trial: 1. Do all patients require the full 6 months of NACT as per KEYNOTE-522 or is there a subgroup of patients who are sufficiently treated with 12 weeks of NACT plus PEM? 2. Can incorporation of ADCs into the KEYNOTE-522 regimen improve response and outcomes in patients without an optimal early response? The outcome of patients with residual disease after 24 weeks of NACT and PEM remains suboptimal and there is an urgent need for more effective strategies. ADCs such as SG have demonstrated superior efficacy compared to standard chemotherapy in metastatic TNBC, resulting in substantially higher response rates and improved progression-free (PFS) and OS. Combination studies of ADCs and immunotherapy in metastatic TNBC have demonstrated significant activity, suggesting possible synergistic activity It is therefore a logical next step to investigate, whether the incorporation of SG in the NACT regimen can improve pCR rates and EFS results in patients who have residual clinical disease after 12 weeks of NACT with CARBO/PAC + PEM.

NCT06497582
The proposed study will be a 3-arm, parallel-group randomized controlled trial on the effects of self-acupressure and Zhan-Zhuang for alleviating pain, fatigue, and sleep disturbance in breast cancer survivors. Subjects will include 54 breast cancer survivors who have experienced a moderate level of pain, fatigue and sleep disturbance. All eligible subjects will be randomized into one of the three groups in a 1:1:1 ratio: Zhan Zhuang group, or self-acupressure group, or wait list control group. Subjects in the Zhan-Zhuang group will receive up to 8 weeks of the intervention consisting of a training course over two weeks followed by self-practice for 6 weeks. Those in the self-acupressure group will attend an acupressure training course for two weeks and then, will be asked to practice self-acupressure for 6 weeks. The wait list control group will be provided with delayed self-acupressure or Zhan Zhuang at the end of the study. Outcome assessment will be conducted at baseline, week 8 (post-intervention) and week 12 (4 week follow-up). Primary outcomes include pain, fatigue and sleep disturbance. Secondary outcomes include psychological distress and health-related quality of life. Qualitative data will be collected from selected participants who have received the intervention.

NCT05871008
Aging is the greatest risk factor for cancer incidence and mortality. Geriatric screening is recommended to help with treatment discussions, inform intensity of treatment, and identify supportive care needs. Despite a strong evidence base, geriatric assessments are not implemented routinely in oncologic clinics. Similarly, important information on social determinants of health, mental health, and health behaviors are inconsistently assessed, and almost never in an integrated fashion. In an effort to support clinicians delivering the recommended goal-concordant care, the investigators will integrate assessment of geriatric issues, health behaviors, mental health, and social determinants of health into an efficient, actionable contextual assessment system for older cancer patients called Integrated Aging Assessment for Action for Cancer Patients (IA3-CP). The investigators will use D\&I strategies including co-creation engagement approaches and form-function methods to develop workflow processes that feasibly integrate the IA3-CP into usual initial assessment with the oncology team. Our objective is to develop and conduct a randomized pilot of the IA3-CP system and hypothesize that our results will show it can be implemented consistently, acted on, improve quality of care, and enhance patient-provider interactions.
