What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests different chatbots, including MARVINA, specifically designed for breast cancer patients. The goal is to adapt these chatbots for various health conditions and groups, such as pharmacists and people with HIV. Participants will use the chatbot and provide feedback to help improve it. Ideal candidates are individuals with breast cancer who are comfortable using Facebook Messenger and have reliable internet access.

As an unphased trial, this study allows participants to contribute to innovative technology that could enhance support for various health conditions.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this protocol is safe?

Research has shown that specific safety information for MARVIN or its versions, such as MARVINA, is not available in humans. This trial examines how people use and adapt to MARVIN, rather than conducting traditional safety testing. As a chatbot, MARVIN communicates with users through text or speech. Unlike medicines or medical devices, chatbots do not cause physical side effects. Instead, safety concerns focus on protecting users' privacy and handling data properly. The goal is to ensure the chatbot is easy and safe to use without causing confusion or stress. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the MARVIN Chatbots for Breast Cancer because they explore a new frontier in patient support and education through AI-driven technology. Unlike traditional treatments for breast cancer, which primarily focus on medical interventions like surgery, chemotherapy, and radiation, these chatbots aim to enhance patient care by providing tailored information and emotional support. The MARVINA chatbot, specifically designed for breast cancer patients, offers a unique approach by co-constructing personalized interactions, assessing usability, and continuously improving based on user feedback. This could revolutionize how patients manage their treatment journey, making the process more engaging and supportive.

What evidence suggests that this trial's chatbots could be effective for breast cancer and other health domains?

Research has shown that AI chatbots, such as MARVINA, can assist breast cancer patients. Studies have found that these chatbots enhance patients' understanding of breast cancer, aiding them in learning more about their condition. For instance, one study found that users of an AI chatbot gained significant knowledge about breast cancer throughout their experience. Another study demonstrated that these chatbots also help patients feel more in control and informed about their treatment options. This evidence suggests that MARVINA could be a valuable tool for those dealing with breast cancer. ^{1 6 7 8 9}

Published Research Related to This Trial

A study involving 215 neoplasm patients over two years showed that a pharmacists-managed outpatient clinic effectively identified and resolved drug-related problems (DRPs), with 82.6% of issues confirmed as resolved after pharmacist interventions.

Pharmacists played a crucial role in improving patient care, as 90.3% of their planned interventions were accepted by patients or physicians, highlighting their importance in managing medication therapy for cancer patients.

Between 1999 and 2003, a study at Toulouse University Hospital reported 613 adverse drug reactions (ADRs) from antiretroviral drugs affecting 428 patients, highlighting the importance of monitoring these effects.

Most reported ADRs (88.6%) were classified as 'non-serious', but 57% of cases required stopping the suspected medication, indicating that while many reactions were mild, a significant portion still necessitated intervention.

A study involving 143 patients receiving immune checkpoint inhibitors showed that intensive pharmacist follow-up and education led to 1664 interventions, significantly improving patient management of immune-related adverse events.

Patients in the pharmacist-supported cohort had lower odds of treatment discontinuation due to immune-related adverse events compared to a control group, with an odds ratio of 5.5, indicating that pharmacist involvement can enhance treatment adherence and outcomes.

This study aims to improve care for patients with chronic myeloid leukemia (CML), chronic lymphocytic leukemia (CLL), and multiple myeloma (MM) by coordinating care between oncology and primary care pharmacists, focusing on patients taking oral anti-cancer agents (OAAs) and managing multiple chronic conditions.

The Pharmacists Coordinated Care Oncology Model (PCOM) will assess the effectiveness of this coordinated approach over two months, measuring medication adherence and patient-reported outcomes, with the goal of enhancing treatment management and overall patient care.

Highly active antiretroviral therapy (HAART) has significantly improved life expectancy for HIV-infected individuals, making it comparable to the general population, but these patients still face increased cardiovascular risks and certain cancers even with undetectable viral loads.

Clinicians need to be aware of potential drug interactions between antiretrovirals and other medications, as these can lead to serious health risks; combinations of two nucleos(t)ide reverse transcriptase inhibitors with raltegravir or dolutegravir are noted to have fewer clinically significant interactions.

In a study assessing the quality of responses from AI chatbots ChatGPT and Bing regarding cancer-related questions, ChatGPT scored an average of 3.9 while Bing scored 3.2, indicating that ChatGPT provided higher quality information overall (P < 0.001).

Despite the potential of AI chatbots in healthcare, the study revealed that 3% of ChatGPT's responses and 15% of Bing's responses had serious shortcomings, highlighting the need for ongoing improvements to ensure accurate and supportive information for cancer patients.

In a study of 898 ambulatory cancer patients on oral anticancer treatments, 46% experienced potential drug-drug interactions (PDDIs), with 16% having major interactions that could significantly impact their treatment.

The most common major PDDIs involved coumarins and opioids, often leading to serious effects like central nervous system issues, gastrointestinal toxicity, and prolonged QT intervals, highlighting the need for increased awareness among healthcare providers.
