PARPi's & ARPi's

Updates (minor tweaks) to the CRS & ICANS grading, along with some newly (or new to me) defined toxicities following immune-effector cell (e.g., CAR-T or Bispecific T-cell engagers) therapy are reviewed. ASTCT link: https://doi.org/10.1016/j.jtct.2026.05.020 ZINCLO-HAND investigates the combination of oral zinc and topical clobetasol to prevent hand-foot skin reaction in patients starting regorafenib. Finally, amivantamab-hyaluronidase gets an accelerated FDA approval for p16-negative head & neck cancer in the recurrent/metastatic setting following earlier treatment with both a platinum and ICI. Also, pimicotinib is a new CSF1R inhibitor approved for tenosynovial giant cell tumor. Download the Learning Oncology Companion: www.kelleycpharmd.com/learning-oncol…nion-oncopharm

This episode looks at the combination of PARP inhibitors in combination with androgen receptor pathway inhibitors (ARPi) for untreated advanced prostate cancer.

ESMO 2026 concluded this past weekend, so this Pod is packed with lots of updates! 1. DeLLphi-305: Maintenance tarlatamab + durvalumab improves OS compared to maintenance durvalumab in extensive stage SCLC. Impressive improvement, but a puzzlingly high rate of dysguesia in the tarlatamab arm that is ~2x what has been reported in tarlatamab monotherapy. 2. Non-ESMO, but related - Lurbinectedin's mono therapy approval for SCLC was was withdrawn following the negative results of the LAGOON trial, which followed the negative results of the ATLANTIS trial. 3. INTerpath-001 was a phase III trial that showed improved recurrence free survival with intismeran autogene + pembrolizumab vs. pembrolizumab in advanced melanoma. This patient-specific mRNA treatment is exciting with more trials planned across solid tumors. 4. Darolutamide may have a role in high-risk prostate cancer following prostatectomy and adjuvant ADT, but longer follow-up (and publication) is likely needed before implementation. 5. VOLGA provides evidence for another sandwich approach in muscle-invasive bladder cancer with durvalumab + enforumab vedotin --> radical cystectomy --> durvalumab (But no more EV). The addition of the CTLA-4 targeting agent tremilimumab appeared to offer no additional benefit. 6. Pemroblizumab's sight agnostic accelerated approval for high Tumor Mutation Burden (TMB) was narrowed from 10+ to 13+ mutations/megabase after a few hundred more patients enrolled and 6 years of follow-up. 7. Adding venetolcax to DA-EPOCH-R in double-hit NHL was associated with excess mortality. Download the Oncology Learning Companion: https://www.kelleycpharmd.com/learning-oncology-companion-oncopharm

This week we take a (brief) stop back in time to the beginning of dostarlimab's journey that has ended (for now) in an accelerated approval for rectal cancer that is mismatch repair-deficient or high in micro-satellite instability (MMRd/h-MSI).

This week we discuss the recent RCT of blinatumomab-ponatinib in Ph+ Adult ALL and how this regimen compares to previously publishes uses of Blin-Ponatinib in induction treatment. Link: DOI: 10.1056/NEJMoa2606208 Finally, we discuss two recent expanded indications in bladder cancer (nogapendekin alfa inbakicept + BCG) and colon cancer (atezolizumab with FOLFOX for dMMR colon cancer in the adjuvant setting).

Tucatinib gets an expanded FDA approval in the 1st-line treatment of HER2(+) metastatic breast cancer based on the results of HER2-Climb05. Pirtobrutinib also gets FDA approved for initial treatment of CLL/SLL (without 17p deletion).

This week's pod offers a brief review of FGFR inhibitors for cholangiocarcinoma in repsonse to the FDA approval of the latest one, lirafugratinib. LITESPARK-011 demonstrated improved PFS of lenvantinib + belzutifan vs. cabozantinib in the 2nd-line setting of advanced ccRCC. This led to a recent FDA approval. We look at the toxicity, QOL, and OS data known about this combination regimen. Download the Learning Oncology Companion: https://www.kelleycpharmd.com/learning-oncology-companion-oncopharm

Drugs that inhibit signaling via the PI3K pathway (e.g. alpelisib, capivasertib) can cause hyperglycemia. The mechanism of this ADR as well as the implications of which anti-diabetes medications are used in response is discussed.

Press Releases are an increasingly common method to learn about new/upcoming data. What can clinicians learn (and what can't we learn) from these? We read through two examples for just this purpose.
