Bluestar Managing Director Erin Olsen is back from the ASCO conference in Chicago and joins Principal Jeff Fineberg on the podcast again, this time to talk about all things antibody drug conjugates (ADCs) in oncology.

Given the number and value of deals in this space over the past couple of years, as well as the 170+ ADCs now in clinical development, Jeff asks Erin to take stock of what we’ve learned about the potential of these molecules, with all their moving parts, and opine on what lies ahead.

Over the course of this brief conversation, Erin and Jeff touch on some key questions about ADCs, including:

• Are ADCs living up to their promise? (1:48)
• What are some lessons learned from Enhertu? (3:20)
• What have we learned about TOP1 payloads and TROP2 targeting? (6:10)
• Have ADCs delivered on better safety than chemo? (8:40)
• What’s next for ADCs? (10:50)

As the Bluestar team prepares to head to ASCO 2024 this upcoming weekend, Bluestar Principal Jeff Fineberg sits down with Bluestar Managing Director Erin Olsen to talk about interesting abstracts related to two topics:

1. What are the unmet needs in 1L therapy?
2. The KRAS G12C mutation landscape

After attending ASN Kidney Week, Bluestar Principal Jeff Fineberg sits down with Dr. Pietro Canetta to talk all things IgA nephropathy (IgAN). After Dr. Canetta provides a brief summary of his IgAN lecture at Kidney Week, Emerging Therapeutic Options in IgA Nephropathy, the two discuss the Filspari (sparsentan) data presented from both the PROTECT study, in IgAN, the DUPLEX study, in FSGS. From there, Dr. Canetta opines on the value of surrogate endpoints in predicting the three D’s of CKD: death, dialysis, and doubling of serum creatinine (SCr). Dr. Canetta briefly discusses Novartis’ press release announcing the positive Phase II data with atrasentan, another ETA RA, before the conversation shifts to other drug classes and therapeutic targets, including SGLT2 inhibitors, and B-cell activation (i.e., APRIL/BAFF). Finally, Jeff asks Dr. Canetta about whether the recent advancements in IgAN are generalizable to other glomerular diseases, and what might be the determinants of this.

In the first ever Biotech Matters podcast episode, Principal Jeff Fineberg, PhD, sits down with nephrologist Beatrice Goilav, MD, to talk all things Kidney Week. Dr. Goilav offers her thoughts on an ideal day-by-day itinerary, as well as her hopes for what will be presented at a variety of sessions, including drug trials in IgAN, and new studies of SGLT2 inhibitors. She also offers her perspective on the potential for complement inhibitors in glomerular diseases, and which of these drugs in development she is most interested in. Finally, she makes some recommendations on poster abstracts to visit in the exhibit hall.
