Latest / EHA Unplugged / Hematology Portraits: Prof Maria Domenica Cappellini
Transcript
- 0:03Greetings and welcome to EHA Unplug, the official podcast
- 0:06channel of the European Hematology Association EHA.
- 0:10Hello, I am Isabella Livera, a medical writer for EHA.
- 0:15Today we're thrilled to have with us Professor Maria Domenica
- 0:18Capellini. Professor Capellini is a
- 0:20Professor of medicine at the University of Milan, and she's a
- 0:24leading authority in hematological disorders such as
- 0:27thalassemia, sickle cell disease and anemia.
- 0:31For her outstanding career dedicated to the understanding
- 0:35and management of these diseases, she received the John
- 0:39Bernard Lifetime Achievement Award at the EHA Congress in
- 0:44this year, 2024. And so we want to revisit your
- 0:49career with you in this podcast. Welcome, Professor Cappellini,
- 0:54and thank you very much for being with us today.
- 0:57Thank you. For inviting me.
- 1:00To start off, I wanted to go really back in time and can you
- 1:04explain us what inspired you to work on Telecenia and hemoglobin
- 1:10at the parties in general? We have to go back to.
- 1:14My. Residency time which?
- 1:16Means the end of 60, early 70 when I was doing my training in
- 1:23internal medicine. And they was.
- 1:25Trying to find out something. Interesting to develop.
- 1:33And to get involved and. I had to.
- 1:38Thank my mentor. Who at that?
- 1:41Time he inspired me. Because, he said listen.
- 1:45Could you be interested in a disease?
- 1:49Which is not. So common now in internal
- 1:52medicine. But it will.
- 1:54Be in the. Future because pediatrician are
- 1:58started to take care properly. Of this patient.
- 2:02They. Are the thalassemia patients?
- 2:05I was a bit shocked because thalassemia.
- 2:09Was not common in our region. I'm living in northern Italy in
- 2:15Milan. Was more common in South in the
- 2:18island. So I say both.
- 2:20That's quite strange, but. Let me see.
- 2:24So I started. To look more.
- 2:26Carefully. In In in patients admitted to
- 2:31the internal medicine world. I started.
- 2:34To look more carefully to the anemia in this patient, any kind
- 2:38of anemia. And at one point I encountered
- 2:45the patients admitted for mild anemia, mild splenomegaly, mild
- 2:55jaundice. And he was admitted because.
- 2:58Of persistent. Fever He.
- 3:00Was a man of. 45 years of age and what was surprising me was
- 3:07the microcytic. Anemia.
- 3:09So he had the. Small red cells.
- 3:13But of course he is. Iron was totally normal, so I
- 3:18said let's see, he was. From Sardinia a.
- 3:21Region. With a high prevalence of
- 3:23thalassemia. So I said, let's see, maybe.
- 3:26He's a carrier, but it. Turn out that he was not a
- 3:30carrier. But he he was an affected
- 3:33patient. With severe thalassemia, the one
- 3:38we used to call thalassemia major.
- 3:41And that was really surprising because.
- 3:44How can a 45 year man? Be alive.
- 3:49Being a thalassemia major. So that's actually excited.
- 3:54Me I. Started.
- 3:55I asked him to. Look at all the family and.
- 3:59He has three children and the three children.
- 4:02Two of them. Were carrier of.
- 4:05Beta thalassemia, but. They had unexpectedly high
- 4:10level. Of fetal hemoglobin, which was
- 4:12not common in a. Carrier.
- 4:14Something like around 810%. This was another.
- 4:19Surprising finding in the family.
- 4:22So I say what? What is going on here?
- 4:25So I. Start to contact expert in the
- 4:28field Professor Bernini Leyden, who confirmed the my observation
- 4:35and then. I contacted Professor Weatherall
- 4:38in. Oxford and starting from this
- 4:41family. I was.
- 4:43Becoming very much interested in the field of hemoglobinopathies
- 4:48and just happened that. Professor Weatherall invited.
- 4:53Me to attend the course in Columbavion, IN.
- 4:57Crete where the. Biggest name in the field where
- 5:03meeting. To share the.
- 5:07Starting molecular work on the. Field so I.
- 5:11Went there and my family was becoming a important.
- 5:18Core of discussion. And then I went to Oxford.
- 5:22For a period. And and and my interest was
- 5:26focused. On that, that was.
- 5:28About was around the end of 70 when the treatment the.
- 5:36Standard of. Care for thalassemia.
- 5:39Was just let's. Say define better in terms of
- 5:45transfusion and iron. Chelation.
- 5:49And at that time it was very demanding because particularly
- 5:53iron chelation was mainly on using diferioxamine.
- 6:03Which? Needed to be.
- 6:05Efficacious. To be infused with the pump for
- 6:11more than 7/8. Hours per day all over the life.
- 6:17So I said that that's. Really something very demanding
- 6:22for the patients, why we are not going to find something new for
- 6:27iron chelation. And since I came back from
- 6:30Oxford, I, I. Started to.
- 6:33Work with Novartis. That at that.
- 6:38Time was, was. Producing the cerioxomy.
- 6:41To find that there are alternative chelator and it come
- 6:45out. That by the.
- 6:48End of 90. The Ferrazirox.
- 6:52Was identified among more than 700 compounds.
- 6:58I was. Leading clinical trial which is
- 7:02novel. Oral iron chelator, which is
- 7:05now. The standard of.
- 7:07Care. And.
- 7:08I personally believe that this was.
- 7:12Really an important step for the management of thalassemia.
- 7:17Because it really. Change.
- 7:21The quality of life of. Patients adherence was increase,
- 7:26compliance were increase. And so so.
- 7:29Since then I will do I maintain contact.
- 7:35With the Oxford. Group and we did some other
- 7:38scientific work, but I. Focus.
- 7:43Mainly starting from the 19. Early 2000.
- 7:47I. Focus a lot.
- 7:49On. Therapeutic approaches in order
- 7:54to offer to these. Patients better.
- 7:58Quality of life. Trying to identify.
- 8:01Some alternative to transfusion and so on.
- 8:05When did you discover the molecular basis of thalassemia?
- 8:10Because that was before knowing your work.
- 8:13In exactly the definition of. Thalassemia, clinically
- 8:17speaking, was given to Doctor Cooley in 1925.
- 8:25But it was. Only after.
- 8:28The 60. When a technique.
- 8:32To separate the. Globin chain of hemoglobin.
- 8:37Was set up that it was possible to say.
- 8:42Thalassemia is a type of anemia due to globin chain deficiency.
- 8:50And that. Was an important step, and that
- 8:52was in 1966. After that.
- 8:58When in. The 80, the.
- 9:01Molecular techniques were made available.
- 9:05Thalassemia was. Characterized at genetic level.
- 9:11And of course, hemoglobin is for.
- 9:15My alpha. And beta globin.
- 9:16Chain so two major group of. Thalassemia were identified
- 9:21according to. The molecular defects on the
- 9:24alpha. Globin or beta globin?
- 9:26Of course, the beta. Thalassemia are the most
- 9:31important clinically speaking. Because you have only. 2 gene
- 9:36which are controlling the. Beta globin production where
- 9:40they ask for alpha you have 4 gene.
- 9:42So I'm not going into. Details, but we focus on beta
- 9:46thalassemia. We characterize the molecular
- 9:50defects of. Vitasalasemia in Italy, but then
- 9:55we did in many. Other we collaborate.
- 9:57To do in many other countries and for.
- 10:00That. Patient I mentioned for that
- 10:02family. What was?
- 10:04The important. Observation was that he was
- 10:08carrier of two affected the. Beta globin drain.
- 10:14So he was hemodigos for the defect, but he had a persistence
- 10:21of. Fetal hemoglobin.
- 10:24So he. Continue after birth during his
- 10:28life to produce fetal hemoglobin.
- 10:31Which compensate the deficiency of beta, so this.
- 10:35Was an important discovery. Which actually open the view of.
- 10:45Finding the. Possibility to treat and to
- 10:49correct beta. Thalassemia inducing the fetal
- 10:52hemoglobin production. This is gene therapy now.
- 10:55And now, now the gene editing based on stimulating the
- 11:02hemoglobin production is becoming a reality.
- 11:06So. I think that.
- 11:08That that discovery, which was then supported also by.
- 11:11Study from Sweele, Tain and the other group.
- 11:15But that was. Really a important.
- 11:19Step for. Working on this.
- 11:23Direction. Direction.
- 11:25And my. Fortune, I have to say, was the
- 11:30the possibility of. Following the natural.
- 11:36History of thalassemia. Changing a long time from the
- 11:41very beginning. When I started.
- 11:43When little rose down for treating these.
- 11:47Children who used. To die within.
- 11:51At most the second decade of life.
- 11:54So I had the opportunity to follow step by step.
- 11:58The improvement because. Of iron chelation, the.
- 12:04Improvement on proper transfusion and now I have
- 12:10patients who have. Over 60.
- 12:13And now I'm so happy that these curative treatment.
- 12:19Are probably available. In the near future.
- 12:23We are all very excited about the gene therapy, about the fact
- 12:26that now you can with Crisp Casket 9, reactivate fetal
- 12:33hemoglobin, but you had also before used hematopoietic, Yeah,
- 12:39I mean. The first, let's say curative
- 12:44approach. Was.
- 12:46Bone marrow transplantation. And the first bone marrow
- 12:49transplantation. Was.
- 12:50Performed in 1981 and there. Was a huge debate at that.
- 12:58Time because you know. That for.
- 13:01Performing bone marrow transplantation you need to do
- 13:05myroblation, which. You know.
- 13:09Both will fun and very. Difficult drugs and.
- 13:15The very beginning. Actually, we lost.
- 13:19Several patients because was not clear how to conditioning them.
- 13:26How to they? May have.
- 13:30Graft versus source. The reaction?
- 13:33So all these things were a bit difficult to face.
- 13:38Because thalassemia is different than leukemia, I mean we have to
- 13:42consider many different factors involved in bone marrow.
- 13:48Transplantation. So at the beginning there was a
- 13:50lot of debate. Among those who.
- 13:53Sustained the. Idea of.
- 13:54Bone marrow transplantation. And those who were more in
- 13:58favour of improving the standard of care.
- 14:00But then step by step. And thank you to the Italian
- 14:04group. Of.
- 14:05Professor Luccarelli in Pesaro, all these let's.
- 14:11Say difficulties were overcome. Improving the protocol.
- 14:19Of. Myroblation improving the.
- 14:23Selection of donors. Now we may.
- 14:27Say that the European Bomar Transplantation Group suggest
- 14:35that. BMT remained.
- 14:38The first choice. In patient age less than 14,
- 14:46having an HLA identical donor. So if.
- 14:51You want to get the. Best result?
- 14:53For bone. Marrow transplantation.
- 14:55This is the. Ideal patient.
- 14:57Still there is a small. Percentage of risk.
- 15:00Of a graft versus soft rejection.
- 15:04What? Is the advantage of gene therapy
- 15:08or genome editing? Where similarly we have to.
- 15:13Perform the mylobulation. But we are.
- 15:17Using the patient. Stem cell.
- 15:21They are manipulated and then they are reinfused.
- 15:24To the patients. So in so in this way we are.
- 15:28Avoiding the risk of. Rejection and that.
- 15:32Is a step forward. Any anyway today having gene
- 15:39therapy approved in United States and having a genome
- 15:43editing approved in Europe and in the United.
- 15:46States still the, the the. Agency are suggesting to.
- 15:55Perform these approaches. In patients who don't have any
- 16:00HLA identical donor for bone marrow.
- 16:04Transplantation. So the problem which in therapy
- 16:09that always comes up is the price tag, obviously.
- 16:14The cost is very high due to the.
- 16:18You know. All the step.
- 16:20You need to do the. Affairs.
- 16:22And then you need to send the stem cells.
- 16:27To a specific lab who? Can do the insertion of gene in
- 16:33case of gene addition gene. Therapy or?
- 16:37Modifying the genome in the case.
- 16:40Of. Gene editing by.
- 16:42Crisp gas. What is extremely important is.
- 16:48To look carefully to the characteristic.
- 16:52Of patients. To be eligible for this.
- 16:56Kind of treatment. I don't believe.
- 16:58That any patients can be treated with gene therapy or genome
- 17:03editing, but. To be successful, I personally
- 17:07believe that as it was for bone marrow.
- 17:10Transplantation is extremely. Important to identify the right
- 17:15patients with low. Comorbidity, for example.
- 17:20And that's. Bring me back.
- 17:22Again to consider. The younger.
- 17:24Population instead of the oldest because.
- 17:29In older. Patients who already have a lot
- 17:33of comorbidity, you know. Take into account the.
- 17:39Cost we have to. Balance the the.
- 17:42Decision. But and hopefully.
- 17:45As it happens. In.
- 17:46For other the. Treatment if this kind of.
- 17:53Approach starts. To be implemented.
- 17:56Probably the cost also will drop hopefully.
- 18:01These diseases are very prevalent in the South of
- 18:07Europe, middle income countries or low income countries, and you
- 18:10have been also very involved collaborating with these
- 18:13countries. Absolutely see how to manage
- 18:16this. Is there?
- 18:17Yeah, gene therapy there. It seems impossible I think.
- 18:23I actually collaborated a lot with.
- 18:28Middle East country. Especially Egypt.
- 18:31Lebanon, Oman and so on. And they did a lot of progress
- 18:36is I have to say. But then I also contributed to
- 18:42improve the standard of care in India, in China where the all,
- 18:47in Thailand where the number of patients are so.
- 18:51Huge in. India, for example and often.
- 18:56It's difficult for. Them even to.
- 18:58Get blood or iron collision. Now I, I.
- 19:04Should say that a lot. Has been done for.
- 19:07Thalassemia, but also for sickle cell disease all over the.
- 19:11World and thanks. Also to the.
- 19:14Thalassemia International Federation.
- 19:17Which is a. Patient association the
- 19:21knowledge is and the management background has been.
- 19:27Spread over the world, so the level is quite good, but there
- 19:32are. Countries where still.
- 19:34There are a. Lot of unmet.
- 19:35Need, but paradoxically. I want to tell.
- 19:38You that for example in. India where there?
- 19:44Is a huge. Bias between rich and poor
- 19:49population or. In other country.
- 19:55Some families are. Ready to move?
- 20:00To gene therapy. Even if the cost is very high
- 20:03because they are rich people. And they can do that.
- 20:06I feel that we are moving to the equity.
- 20:10You know. Is a huge a huge problem to
- 20:13face. You have also been involved in
- 20:17the development of a TGF beta inhibitor Leuspater Sept.
- 20:24Yes, other approaches to treating these that should be
- 20:27cheaper. How is this going?
- 20:29Yeah, and now there are. Other molecules.
- 20:33Such as Metapivat. Which is a PK stimulator.
- 20:39I was involved in leuspatercept trials.
- 20:45Leuspatercept is. Now registered and.
- 20:49Officially available. In the market in many countries
- 20:54in this case. The treatment is not.
- 20:58A definitive cure? But.
- 21:00Is improving the burden of blood transfusion and iron chelation
- 21:07and that. Was part of.
- 21:10My. Let's say vision.
- 21:12And my dream to to to find out how to improve the treatment and
- 21:18quality. Of life for this patient.
- 21:20In term of. Cost.
- 21:22It's definitely cheaper, but you have to consider that this
- 21:26treatment should be done for life.
- 21:30So if you collect all together the cost for a life life.
- 21:40Long time it may be. Quite high.
- 21:46Gene therapy genome editing is one shot.
- 21:49If it works. Is done.
- 21:52Of course. The major problem is OK is.
- 21:56One shot, but. Who is supporting?
- 22:00Such a cost. So you have witnessed all these
- 22:05advances from identify even the molecular bases, the genetic
- 22:11bases, identify on the 1st treatments possible so that
- 22:18people could live longer and even now gene therapy, all these
- 22:26creative options. What has been your most
- 22:31enjoyable part of this path, or what have you enjoyed about
- 22:35this? Well.
- 22:39Any opportunity make me enthusiastic and very much
- 22:46looking. Forward I still believe that
- 22:51the. Introduction of the oral iron.
- 22:55Chelator. That's really.
- 22:58Was an important step forward along the thalassemia journey.
- 23:06Although we had. The serioxamine as I mentioned
- 23:10by pamps abacutaneously. But this was.
- 23:13Extremely demanding and at that time around the 80.
- 23:18Were still losing patients because the compliance drop.
- 23:24They didn't want to go on with this difficult.
- 23:27Treatment and that. Was painful because instead of
- 23:31losing. Patient at the age of 10 or 15.
- 23:34But we were. Losing them at the age of 20 or
- 23:3725 with an oral treatment. Which is a pills now.
- 23:44I mean, that's. That's change completely, the
- 23:47adherence, the compliance. And nowaday?
- 23:51Is quite rare to. See patients dying.
- 23:56For heart failure. Due to iron overload.
- 24:00In the heart. We see.
- 24:02Some, of course, because there are patients who are.
- 24:05Resistant to treatment, but now I mean the principal, the main.
- 24:12Cause of death which was heart failure is not.
- 24:19Seen anymore? And that's actually.
- 24:22Made me really. Excited.
- 24:25And that is back to 2000. 5. 2006.
- 24:29When? The Ferraz Xerox was approved
- 24:32there by FDA. And Giba and now is the.
- 24:37Achelators use almost all over the world.
- 24:42With everything that is available, how do you see the
- 24:46management of these patients in the next 10 years advancing?
- 24:51Is it going to advance a lot but or?
- 24:54We have now a huge scenario with some.
- 24:59Pharmacological approaches and some molecular approaches.
- 25:06All of them may have some. Pros and cons?
- 25:13And what I. Believe is.
- 25:17The main. Let's say.
- 25:22The main war. Is really to be able to follow
- 25:28in real life the result of this? Clinical trial and to define the
- 25:35profile of patients who may go in One Direction.
- 25:40Or in other direction and not. Accepting without thinking.
- 25:47Which is the best one because the.
- 25:50Patients have different 1 by 1, so the near future and I will
- 25:55not. Be there to look at that, but
- 25:59for. Something that I really.
- 26:01Suggest to the. Younger Fellow.
- 26:04Facing the treatment. Of thalassemia.
- 26:06To look carefully at the profile.
- 26:09Of the patient. So now is to be very careful
- 26:13which patient gets which type of.
- 26:15Type of therapy. Yeah, that's where we're at,
- 26:18which is a very nice place to be.
- 26:20Wow, compared to where you started?
- 26:23I work on this field. For more than 45 years and for
- 26:2740 years. I had nothing else than.
- 26:29Transfusion and collision. Now with, you know.
- 26:34A. New scenario, an exciting time
- 26:38and. Must be really, you know,
- 26:43satisfying to have dedicated your life to this.
- 26:47Yeah, this is. And to see where this is
- 26:52progressing. It's been a pleasure talking to
- 26:54you. Thank you.
- 26:56Thank you very much for coming and participating in this
- 27:00podcast, and thank you to all of our listeners and stay tuned for
- 27:05our next episodes.
