Hospice & palliative care

Clinical Trials and Palliative Care Together

Save

A clinical trial tests a treatment; palliative care makes the person going through it more comfortable. The two are built to coexist. Understanding the difference between palliative care and hospice — and how eligibility for each works — is what keeps families from turning one down by mistake.

Can you have palliative care during a clinical trial?

Yes. Palliative care is specialist support for the symptoms, stress, and daily burden of a serious illness, and it is built to run alongside active treatment of any kind — including a drug or procedure being studied in a clinical trial. It can begin at any stage of the illness, at the same time as treatment meant to cure or control your disease, and enrolling in a trial does not require you to decline it 1.

The trial and the palliative team are solving different problems. The trial is testing whether a specific treatment changes the course of your disease. Palliative care is making sure you can tolerate the weeks and months while that question is answered — treating pain, breathlessness, nausea, fatigue, fear, and the practical strain on your family. Neither one cancels the other out, and there is no rule that you must choose between them.

How palliative care is different from hospice

Palliative care and hospice are not the same thing, and the difference is what decides whether each fits with a trial. Palliative care is given at any stage of a serious illness, alongside treatment intended to cure or control it. Hospice is comfort-focused care for the final months, chosen when treatment aimed at curing the illness has stopped — and hospice is itself a form of palliative care used near the end of life 2.

That is why a disease-directed clinical trial and palliative care go together, while a curative trial and hospice generally do not. Choosing hospice usually means stepping away from treatment aimed at the terminal illness, which is the opposite of what a trial is doing. This is also where the language blurs, so it is worth getting palliative vs comfort care straight, and both apart from hospice, before turning anything down.

What does the evidence show about adding palliative care?

Adding palliative care during active treatment has been tested in randomized trials, and the results point one way: people tend to feel better. In a randomized trial of adults with advanced cancer, a nurse-led palliative care program delivered alongside standard oncology care improved quality of life and lowered depressed mood compared with usual care 3.

A separate cluster-randomized trial of early outpatient palliative care in advanced cancer found better quality of life and greater satisfaction with care, with the difference clearest by about four months 4. The benefit is not confined to palliative care for cancer: a randomized trial in Parkinson's disease and related disorders found that integrated outpatient palliative care improved quality of life and symptom burden at six months compared with standard care 5. This evidence is part of why clinicians increasingly favor starting palliative care early rather than saving it for the very end.

What kinds of symptoms can palliative care help with?

Palliative care covers the whole weight of a serious illness, not just one symptom. Alongside a trial, a palliative team commonly helps with pain, breathlessness, nausea, poor appetite, constipation, fatigue, trouble sleeping, and the anxiety and low mood that ride along with a hard diagnosis. It also addresses the practical and emotional load — coordinating appointments, explaining what to expect, and supporting the family.

This matters for a trial in a concrete way. Unmanaged side effects can make it harder to continue a demanding treatment, so keeping symptoms under control can help some people stay on the therapy they are trying. The randomized evidence that concurrent palliative care improves quality of life and mood is exactly this effect, measured 3.

Does palliative care affect your place in a trial?

Generally, no. Palliative care is supportive care, not an experimental therapy, so it does not compete with what a trial is testing. A trial studies whether a specific drug or procedure changes the course of your disease; palliative care manages symptoms and quality of life while that question is answered 1.

Clinical trials do set their own eligibility rules and keep their own lists of medicines that are permitted or restricted during the study. Because of that, the practical step is to make sure the research coordinator and the palliative team each know what the other is doing, so no supportive medicine conflicts with the protocol. People often begin looking at trials when standard options are limited, and clinical trials eligibility for late-stage disease is worth asking about in the same breath as symptom support — the two belong in one conversation, not one after the other.

What does a palliative care team do?

A palliative care team is an added layer of support that works with your other doctors rather than replacing them 2. It usually brings together physicians, nurses, social workers, and often chaplains who focus on pain and other physical symptoms, the emotional and practical strain of serious illness, and clarifying what matters most to you and your family.

During a trial, that can mean managing side effects so you are able to stay on the study, coordinating between the research team and your regular clinicians, and supporting the people caring for you at home. You keep your oncologist or specialist and the trial's investigators; the palliative team is added alongside them. Children with serious illness can receive this help too, and pediatric palliative care follows the same principle of running alongside treatment.

How do you decide between — or combine — a trial and palliative care?

Deciding whether to join a trial, add palliative care, or do both is a shared decision between you and your clinicians, not something you have to settle alone. AHRQ's SHARE Approach lays out five steps for that conversation: seek your participation, help you compare the options, assess your values and preferences, reach a decision together, and evaluate it over time 6.

Because palliative care can begin early and alongside treatment, it is usually added at the same time a trial is being weighed, not chosen instead of it. A good first move is a palliative care referral — many people simply ask their doctor for palliative care and let the office arrange it. Questions about cost, such as palliative care and Medicare coverage, are a separate track from whether a trial will accept you. And if standard options are running short, a second opinion at an academic center with advanced treatment options can surface both trials and palliative support at once.

Common questions

No. Palliative care treats symptoms and stress and is designed to be given alongside treatment aimed at curing or controlling your illness, including an experimental treatment in a clinical trial. It can start at any stage. Choosing it does not mean stopping the treatment you are pursuing or leaving a trial you have already joined.

Usually not, and this is where palliative care and hospice differ. Electing the Medicare hospice benefit generally means stepping away from treatment aimed at curing the terminal illness — the opposite of what a disease-directed trial does. Palliative care is the option that runs alongside a trial. If a trial matters to you, that is a reason to ask about palliative care rather than hospice.

Generally no. Palliative care is supportive care, not an experimental therapy competing with what the trial studies. Trials do keep their own lists of permitted and restricted medicines, so tell the research coordinator about every medicine and supportive treatment you receive, and ask the palliative team to coordinate directly with the study team.

It can begin as soon as a serious illness is diagnosed, at the same time as active treatment, and does not have to wait until treatment stops working. Randomized studies of starting palliative care early alongside cancer treatment have found better quality of life. Many people ask for it at the same visit where a trial is first discussed.

Palliative care is usually delivered by a team — physicians, nurses, social workers, and often chaplains — who work with your existing doctors rather than replacing them. During a trial they help manage side effects, coordinate between the research team and your regular clinicians, and support your family. You keep your oncologist or specialist and the trial's investigators.

When symptoms can't wait

  • —New or worsening trouble breathing, or breathlessness while sitting still
  • —Pain that your current medicines no longer control, severe enough to stop you sleeping, eating, or moving
  • —A fever, shaking chills, or any symptom your trial team told you to report immediately while on an experimental treatment
  • —New confusion, fainting, a fall, or a seizure

For a life-threatening emergency — severe trouble breathing, chest pain, fainting, or a seizure — call 911 or go to the nearest emergency room. If you are having thoughts of suicide, call or text 988 for the Suicide and Crisis Lifeline.

This article explains how palliative care and clinical trials fit together. It is educational and not medical advice. Decisions about joining a trial, adding palliative care, or any medicine belong to you, your own clinicians, and the trial's research team, who know your situation.
