If high-grade cancer keeps coming back even after BCG, that can
feel discouraging. Here is the encouraging part: there are now
more approved options than ever, several of them brand new,
that aim to treat the cancer while keeping your bladder. This page explains
what "BCG didn't work" means and walks through the options your doctor may
discuss. It does not rank them — the right choice depends on your case.
Doctors use the term "BCG-unresponsive" for high-grade,
non-muscle-invasive bladder cancer that keeps coming back or does not go
away even after an adequate amount of BCG.
"Adequate BCG" is a specific amount your doctor can define for you — it
generally means you received enough BCG for a fair test of whether it would
work.
Meeting this definition matters because it is the doorway to several
treatments and clinical trials that are approved specifically for
BCG-unresponsive cancer. Ask your doctor plainly:
"Do I meet the definition of BCG-unresponsive?"
Coming back after BCG is not the same as the cancer
spreading. Most of these tumors are still on the bladder lining.
But it is a signal to change the plan, which is why the options below
exist.
Options your doctor may discuss
Each card below follows the same layout so you can compare them. None is
presented as better than another — that depends on your exact cancer, your
health, and what matters to you.
Adstiladrin (nadofaragene firadenovec)
Newly approved
What it is
A gene therapy that works with your own immune system to fight bladder
cancer. It uses a virus — one that cannot copy itself or make you sick — to
carry a gene into the cells of your bladder lining. Those cells then make a
protein called interferon alfa-2b, which slows down or stops cancer cells
from growing and helps your immune system attack them. It does not change
your other genes.
How it's given
A liquid put into the bladder through a catheter and held there for 1 hour,
in the office. During that hour you change position about every 15 minutes so
the medicine reaches the whole bladder lining.
Typical schedule
Usually once every 3 months, for as long as it keeps
working and you tolerate it.
Common side effects
The most common are discharge from the bladder or around the catheter,
tiredness, bladder spasms, an urgent need to urinate, blood in the urine,
chills, fever, and painful or burning urination. These are usually
short-lived after each treatment.
Red flags
High fever or chills, being unable to urinate, or heavy
bleeding — see the warning-signs panel below.
Questions to ask your doctor
Is my cancer the type this is approved for?
How will we know if it is working, and when?
What happens if it stops working?
Anktiva (nogapendekin alfa) with BCG
Newly approved
What it is
An immune-activating medicine given together with BCG. It
switches on certain immune cells — natural killer cells and T cells — that
help attack cancer, boosting the effect of BCG.
How it's given
Combined with BCG and placed into the bladder through a catheter, then held
there, in the office.
Typical schedule
Given with BCG once a week for 6 weeks to start (an
induction course). If it is helping, maintenance courses of weekly
treatments follow at set months over about the next two to three
years.
Common side effects
Because BCG is part of the treatment, expect BCG-type bladder symptoms —
urgency, frequency, and burning. Other common effects include tiredness,
nausea, bladder irritation, diarrhea, and getting up at night to
urinate.
Red flags
The same BCG warning signs: high fever, shaking chills,
joint aches or rash, or inability to urinate — see the panel below.
Questions to ask your doctor
Does this need BCG to be available, given past shortages?
How is this different from the BCG I already had?
What are the signs it is working?
Inlexzo (TAR-200)
Newly approved
What it is
A small, soft device that is placed inside the bladder, where it coils into
a pretzel-like shape and slowly releases the chemotherapy medicine
gemcitabine over weeks — steady local treatment rather than a quick
instillation.
How it's given
Placed into the bladder in the office in a few minutes through a thin
catheter — no general anesthesia. You urinate normally with it in place, and
it is later removed with a small camera (cystoscopy).
Typical schedule
The device stays in for 3 weeks, then is removed and
replaced with a new one, on a schedule your care team sets.
Common side effects
The most common are needing to urinate often, urinary tract infections,
painful urination, a sudden urge to urinate, blood in the urine, bladder
irritation, and bladder or urinary tract pain.
Red flags
Inability to urinate, severe pain, fever, or heavy bleeding
— see the warning-signs panel below.
Questions to ask your doctor
Is my cancer the type this is approved for, and is it available here?
What is it like to have the device placed and exchanged?
How often would I need visits?
Gemcitabine + docetaxel
What it is
Two chemotherapy medicines placed in the bladder one after the other in the
same visit ("sequential"). Long used by many bladder-cancer centers,
including when BCG has stopped working.
How it's given
Through a catheter in the office: gemcitabine goes in and is held, then
drained, then docetaxel goes in and is held.
Typical schedule
Often weekly for a course, then spaced-out maintenance if it is
working.
Common side effects
Bladder irritation — urgency, frequency, burning — and a longer visit
because of the two hold times.
Red flags
Inability to urinate, heavy bleeding, fever, or severe pain
— see the warning-signs panel below.
Questions to ask your doctor
How does this compare with the newer approved options for me?
How many treatments would I need, and how often?
Pembrolizumab (Keytruda)
What it is
An immunotherapy given as an IV infusion (into a vein),
not into the bladder. It blocks a "brake" on your immune system (a protein
called PD-1) so your immune cells can attack the cancer. It is an option for
high-grade, BCG-unresponsive cancer with CIS in people who cannot have — or
choose not to have — their bladder removed.
How it's given
As an infusion at an oncology or infusion center, every 3 weeks or
every 6 weeks.
Typical schedule
Repeated infusions over time, with scans and visits to check how you are
doing.
Common side effects
Because it works on the whole body, its side effects differ from bladder
instillations. It can cause immune-related effects — the
immune system can inflame almost any organ, such as the bowel, lungs, skin,
or hormone glands — so any new symptom should be reported. Many people
tolerate it well.
Red flags
New or worsening diarrhea, shortness of breath, severe
tiredness, or a bad rash — call your care team promptly, as immune side
effects can be serious.
Questions to ask your doctor
Am I a candidate, and why this instead of a bladder treatment?
What immune side effects should I watch for and report?
Which team manages this — urology, oncology, or both?
Clinical trials
What it is
Carefully run studies testing new bladder treatments. Because
BCG-unresponsive cancer is an active area of research, this group often has
many trial options — a real path, not a last resort.
How it's given
Depends on the trial. Some test a new bladder instillation, some a device,
some an infusion. The trial team explains exactly what is involved before
you decide.
Typical schedule
Set by the trial, with extra visits and monitoring.
Common side effects
Depend on the treatment being studied; the trial team reviews known and
possible effects with you as part of consent.
Questions to ask your doctor
Are there trials I qualify for, here or nearby?
What would I be giving and giving up by joining one?
Can I still choose other treatments later?
Removing the bladder (cystectomy)
What it is
Surgery to remove the bladder. It is the long-standing standard
option for high-grade cancer that BCG has not controlled, and it is
the comparison point that the bladder-sparing options above are weighed
against. It is presented here as a respected choice, not a failure.
How it's given
A major surgery that also creates a new way for urine to leave the body
(a "urinary diversion"). It has its own recovery.
Typical schedule
A planned operation followed by a hospital stay and a recovery period.
Common side effects
Those of major surgery and of living with a urinary diversion. The
dedicated page below explains these in plain language.
Questions to ask your doctor
For my case, how does surgery compare with the bladder-sparing options?
How to use these cards. Bring them to your visit. A good
next step is to ask your doctor to point to the one or two options that best
fit your exact stage, grade, and CIS status, and why.
When to call your care team
Whichever option you and your doctor choose, call the office number on your
discharge paperwork right away, or seek emergency care, if you have any of
these:
A fever of 100.4°F (38°C) or higher, or shaking chills
You cannot urinate at all
Heavy bleeding or many blood clots in the urine
Severe belly or pelvic pain
For infusion immunotherapy: new bad diarrhea, trouble breathing,
or a severe rash — these can be immune side effects
If you have chest pain, trouble breathing, fainting, or
another life-threatening emergency, call 911.
