Latest / Early Edition with Ryan Bridge / Dr Gareth Rivalland: Medical Oncologist and Melanoma Specialist on new Pharmac drug proposal
Transcript
- 0:00Speaker 1: Farmac's looking at funding two new melanoma drugs though benefit
- 0:03Speaker 1: patients with late stage melanoma, saving the health system around
- 0:07Speaker 1: one thousand and fusion hours a year. They are out
- 0:10Speaker 1: for consultation. Doctor Gareth Rivland is with US medical oncologist
- 0:13Speaker 1: and melanoma specialist.
- 0:15Speaker 2: Good morning, all, very much, good to have you here.
- 0:19Speaker 1: What did these drugs do.
- 0:22Speaker 2: So over the last fifteen years or so, Not that
- 0:26Speaker 2: we don't want to take you back too far, but
- 0:29Speaker 2: there's been a real change in the way we treat melanoma.
- 0:31Speaker 2: So we don't use traditional chemotherapies. What we use are
- 0:33Speaker 2: these immunotherapy drugs where we try to get the patient's
- 0:37Speaker 2: own immune system to recognize the cancer cells and attack them.
- 0:41Speaker 2: And so these two drugs are in that group, and
- 0:46Speaker 2: one of them effectively unmasked the cancer to allow the
- 0:49Speaker 2: immune system to see it, and the other drug effectively
- 0:54Speaker 2: cuts the tax on the immune system if you like,
- 0:56Speaker 2: to allow it to run a lot harder, faster, earlier
- 0:59Speaker 2: and treatment. And so these two medications have been around
- 1:03Speaker 2: for a while, but the real change for us now
- 1:06Speaker 2: we can use them before someone has surgery to allow
- 1:10Speaker 2: the immune system to see these cancer cells. Really early
- 1:12Speaker 2: and try to kill them off even before the surgeons
- 1:15Speaker 2: get there.
- 1:16Speaker 1: And they must be used. Therefore they must be used together.
- 1:19Speaker 1: You need to fund them both.
- 1:21Speaker 2: Yeah, well, this is where the state of the art is.
- 1:24Speaker 2: Really this is the best combination. So this is what
- 1:26Speaker 2: we'd say is the global gold standard treatment. So when
- 1:29Speaker 2: you use this combination, you can do two treatment cycles
- 1:33Speaker 2: before surgery, so that's six weeks of treatment and about
- 1:36Speaker 2: sixty percent of people will have the cancer completely killed
- 1:39Speaker 2: off before surgery. So this is quite a change and
- 1:43Speaker 2: it really is better than any other combination or any
- 1:46Speaker 2: other single drug that has been tested around the world.
- 1:49Speaker 1: Do they still need surgery?
- 1:52Speaker 2: Oh, well, that's where we're going next. You know, that's
- 1:54Speaker 2: where the trials are heading at the moment. We need
- 1:58Speaker 2: the surgery to be able to tell how well the
- 2:00Speaker 2: pavement's work. So, as I said, sixty percent of people
- 2:03Speaker 2: in these trials look like that have what we call
- 2:05Speaker 2: a complete pathologic response. That means that when the pathologists
- 2:09Speaker 2: look at the slides, there's no cancer cells left. But
- 2:13Speaker 2: that does leave forty percent who don't get that sort
- 2:15Speaker 2: of response, and we need that understanding of what's happened
- 2:19Speaker 2: on the microscopic level to decide what sort of treatment
- 2:22Speaker 2: they might need sort of after surgery.
- 2:24Speaker 1: I had a look at this this morning. It looked
- 2:26Speaker 1: to me like these are being funded in Australia since
- 2:29Speaker 1: twenty eighteen. Is that I mean it sounds like revolutionary here,
- 2:33Speaker 1: but is that true?
- 2:35Speaker 2: Well, the original trials where we were looking at doing
- 2:40Speaker 2: treatment around surgery was in twenty eighteen. The treatment prior
- 2:44Speaker 2: to surgery, where effectively you leave the tumor in place
- 2:47Speaker 2: to you know, what you're is allowing the immune system
- 2:51Speaker 2: to see these cancer cells really early. That's a later development.
- 2:55Speaker 2: They probably had that treatment in Australia only over the
- 2:57Speaker 2: last two or three years. The combination, as I say,
- 3:01Speaker 2: which is the state of the art and was funded
- 3:04Speaker 2: in August last year in Australia, and in fact it
- 3:07Speaker 2: isn't funded in the UK or Canada. I think are
- 3:10Speaker 2: in the process of rolling it out, but it's not
- 3:12Speaker 2: quite there. So actually we're a little ahead of the
- 3:14Speaker 2: curve on this one, which is unusual for FARMAC.
- 3:18Speaker 1: First first time I've ever heard any doctor tell me that. Gareth,
- 3:22Speaker 1: I appreciate your time this morning, doctor Garethrivaland who's a
- 3:26Speaker 1: medical oncologist and melanomas specialist for.
