For the Season 2 finale, we’re at the 2016 annual meeting of the American Society of Hematology (ASH). You’ll hear from Dr Alexis Thompson, Dr Brian Druker, Dr Bruce Cheson and Dr John Leonard on some of the latest developments in hematology.
Sickle Cell Disease – Interview with Dr Alexis Thompson
Alexis A Thompson MD MPH is Professor Pediatrics (Hematology, Oncology and Stem Cell Transplantation) at the Northwestern University Feinberg School of Medicine in Chicago. A Vice President of the American Society of Hematology (ASH), she will become President in 2018.
Dr Thompson is a leader in sickle cell disease (SCD) and at #ASH16, she introduced the plenary presentation by Dr Kenneth Ataga (UNC) on crizanlizumab for the prevention of pain crises in sickle cell disease. Link to NEJM paper
While treating the symptoms of sickle cell disease (SCD) are important, the hope is that in the future we will be able to cure the disease.
SCD is at the vanguard of research using gene therapy and gene editing techniques.
Dr Thompson presented data at ASH16 on gene therapy for sickle cell disease (Abstract 1175).
Although still only at the preclinical research stage, there was a lot of data at ASH on gene editing techniques such as CRISPR.
Gene editing offers the potential to cure sickle cell disease – expect to hear a lot more about this in the future.
Beat AML Trial – Interview with Dr Brian Druker
Dr Druker is well known for his pioneering research in chronic myeloid leukemia (CML), which led to the development of the targeted therapy imatinib (Gleevec/Glivec) and a revolution in how this blood cancer was treated.
He’s now turning his expertise to acute myeloid leukemia (AML), where there’s a high unmet medical need for new effective treatments in patients over 60.
Dr Druker is one of the lead investigators in the Beat AML trial sponsored by the Leukemia Lymphoma Society (LLS). This is a collaboration of multiple partners:
One of the innovative features of this adaptive trial is that the LLS are the investigational new drug (IND) holders with the FDA. Could this be a model for other advocacy organizations to follow? You can find more information on the LLS website.

Chronic Lymphocytic Leukemia – Interview with Dr Bruce Cheson
In his interview, Dr Cheson talks about some of the challenges with giving targeted therapies upfront (first-line) to younger CLL patients. These include issues of compliance, expense and adverse events associated with long-term daily use until progression; something that may be years in the future.
Will combination strategies allow a discontinuation of targeted therapy in those patients that develop a deep and lasting remission, and who are MRD (minimal residual disease) negative?
Due to time limitations, the podcast only features selected excerpts from the interview with Dr Cheson. Subscribers can read more on Biotech Strategy Blog, “The Changing CLL Landscape Part 1.”
Lymphoma – Dr John Leonard shares #Leonardlist
Like many hematologists, he’s also active on Twitter: @JohnPLeonardMD. Do follow him if you don’t already.
A Top 10 list was a regular feature on “Late Night with David Letterman,” so in the spirit of Letterman, you’ll hear Dr Leonard take us through his Top 10 list (#Leonardlist) of lymphoma abstracts that caught his attention.
If you want to read more, here are the 10 #ASH16 abstracts mentioned:
- No 1 (930 Nivolumab (Anti-PD1) Therapy for Relapsed/ Refractory Primary Central Nervous System Lymphoma and Primary Testicular Lymphoma)
- No 2 (469 Phase III Randomized Study of R-CHOP Versus DA-EPOCH-R and Molecular Analysis of Untreated Diffuse Large B-Cell Lymphoma: CALGB/Alliance 5030)
- No 3 (1217 Ibrutinib As Treatment for Chemoimmunotherapy-Resistant Patients with Follicular Lymphoma: First Results from the Open‑Label, Multicenter, Phase 2 DAWN Study)
- No 4 (182 Brentuximab Vedotin Demonstrates Significantly Superior Clinical Outcomes in Patients with CD30-Expressing Cutaneous T Cell Lymphoma Versus Physician’s Choice (Methotrexate or Bexarotene): The Phase 3 Alcanza Study)
- No 5 (1104 Vitamin D Insufficiency Is Associated with an Increased Risk of Early Clinical Failure in Follicular Lymphoma)
- No 6 (2989 GDPT Versus CHOP in Newly Diagnosed Peripheral T-Cell Lymphoma: A Prospective Randomized Controlled, Open-Label Study)
- No 7 (6 Obinutuzumab-Based Induction and Maintenance Prolongs Progression-Free Survival (PFS) in Patients with Previously Untreated Follicular Lymphoma: Primary Results of the Randomized Phase 3 GALLIUM Study)
- No 8 (145 Rituximab Maintenance after Autologous Stem Cell Transplantation Prolongs Survival in Younger Patients with Mantle Cell Lymphoma: Final Results of the Randomized Phase 3 LyMa Trial of the Lysa/Goelams Group
- No 9 (3034 Time from Diagnosis to Initiation of Treatment of DLBCL and Implication for Potential Selection Bias in Clinical Trials);
- No 10 (LBA-6 Kte-C19 (anti-CD19 CAR T Cells) Induces Complete Remissions in Patients with Refractory Diffuse Large B-Cell Lymphoma (DLBCL): Results from the Pivotal Phase 2 ZUMA-1).
Note: these are not in any rank or order.
There is additional commentary on these on Biotech Strategy Blog,”LeonardList showcases 10 Lymphoma abstracts at ASH16.” (subscription required).
Dr Leonard introduced the ASH16 plenary presentation of data for obinutuzumab in Follicular Lymphoma – No 7 on his list.
At the end of the Novel Targets segment with Dr Leonard, you’ll hear a reference in passing to the iconic, “Desert Island Discs“, a concept created and originally hosted by Roy Plomley, which first aired on 29th January 1942. It’s Britain’s longest running radio show and is well worth a listen.
Podcast Sponsorship – Vignette with Dr Michael Wenger, Genentech
Genentech sponsored this episode of the podcast. We’re grateful for their support!
Instead of reading a corporate message, for Genentech sponsored episodes, we’re doing mini-interviews or vignettes with company scientists.
For this episode, we spoke with Michael Wenger MD PhD, who is a Senior Group Medical Director at Genentech. He heads the development of three products, including the novel antibody drug conjugate (ADC) polatuzumab vedotin, which targets CD79b.
In his vignette, Dr Wenger talks about an ASH16 poster in aggressive lymphomas (abstract 1853), presented by Prof Herve Tilly (Rouen).
Dr Wenger gave a presentation on the ASH polatuzumab data at a Roche analyst event in San Diego (Link).
Here’s the mechanism of action from his presentation:
