In Brief: A Cardiovascular Indication for Tirzepatide (Mounjaro)
The Medical Letter on Drugs and Therapeutics • October 12, 2026; (Issue 1765)
The injectable GIP/GLP-1 receptor agonist tirzepatide
(Mounjaro – Lilly), which was approved by the FDA in 2022
for treatment of type 2 diabetes, has now been approved
to reduce the risk of MACE in adults with type 2 diabetes
who are at high risk for these events. Tirzepatide is also
available as Zepbound for chronic weight management
and for treatment of obstructive sleep apnea in adults with
obesity.

Tezepelumab (Tezspire) for Nasal Polyps
The Medical Letter on Drugs and Therapeutics • October 26, 2026; (Issue 1766)
The FDA has approved tezepelumab (Tezspire – Amgen/AstraZeneca), a subcutaneously administered thymic
stromal lymphopoietin (TSLP) blocker, for add-on
maintenance treatment of inadequately controlled chronic
rhinosinusitis with nasal polyps (CRSwNP) in patients
≥12 years old. It is the first TSLP blocker to be approved
for this indication. Tezepelumab was approved for add-on
maintenance treatment of severe asthma in 2021.

Camizestrant (Etcamah) for Advanced Breast Cancer
The Medical Letter on Drugs and Therapeutics • October 26, 2026; (Issue 1766)
Camizestrant (Etcamah – AstraZeneca), an oral estrogen
receptor antagonist, has received accelerated approval from
the FDA for use in combination with a cyclin-dependent
kinase (CDK) 4/6 inhibitor for treatment of hormone
receptor (HR)-positive, human epidermal growth factor
receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer in adults who have ESR1 mutations that were
detected in circulating tumor DNA (ctDNA) during treatment
with an aromatase inhibitor and a CDK 4/6 inhibitor.
7
Iberdomide (Zenbexus) for Multiple Myeloma (online only)
The Medical Letter on Drugs and Therapeutics • October 26, 2026; (Issue 1766)
Iberdomide (Zenbexus – BMS), an oral first-in-class
cereblon-modulating protein degrader, has received
accelerated approval from the FDA for use in combination
with the CD38-directed cytolytic antibody daratumumab
(Darzalex Faspro) and dexamethasone for treatment of
multiple myeloma in adults who received at least one
prior line of therapy, including a proteasome inhibitor (e.g.,
bortezomib) and an immunomodulatory drug. The drug was
approved based on a surrogate endpoint of minimal residual
disease-negative complete response.
8
Zidesamtinib (Jideytro) – Another Kinase Inhibitor for NSCLC (online only)
The Medical Letter on Drugs and Therapeutics • October 26, 2026; (Issue 1766)
Zidesamtinib (Jideytro – GSK), an oral kinase inhibitor, has
been approved by the FDA for treatment of locally advanced
or metastatic ROS1-positive non-small cell lung cancer
(NSCLC) in adults who received at least one prior ROS1
kinase inhibitor. It is the fifth oral kinase inhibitor to be
approved in the US for treatment of ROS1-positive NSCLC;
crizotinib (Xalkori), entrectinib (Rozlytrek), repotrectinib
(Augtyro), and taletrectinib (Ibtrozi) were approved earlier.

Antiviral Drugs for Seasonal Influenza
The Medical Letter on Drugs and Therapeutics • November 9, 2026; (Issue 1767)
Influenza is typically a self-limited illness, but complications
including pneumonia, respiratory failure, and death can
occur, especially in persons at increased risk (see Table 1).
Influenza vaccination reduces the incidence of laboratory-confirmed influenza and the risk of complications associated
with influenza illness. Annual vaccination should be offered
to all persons ≥6 months old as long as influenza viruses are
circulating in the community.
10
A New Indication for Finerenone (Kerendia)
The Medical Letter on Drugs and Therapeutics • October 5, 2026; (Issue 5134)
The FDA has approved the nonsteroidal mineralocorticoid
receptor antagonist (MRA) finerenone (Kerendia) to reduce
the urinary albumin-to-creatinine ratio (UACR) in adults
with chronic kidney disease (CKD) associated with type 1
diabetes. Reducing UACR is expected to reduce the risk
of sustained eGFR decline and progression to end-stage
kidney disease. Finerenone is the first drug to be approved
in the US for this indication in 30 years.
