How could Immutep's focus on HNSCC affect MSD's drug demand?
Immutep's focus on HNSCC may increase demand for MSD's anti-PD-1 therapy Immutep intends to focus its registration-directed clinical development of efti on HNSCC in patients with CPS, alongside the neoadjuvant setting of STS. This strategic shift suggests continued and expanded clinical activity. Since Immutep already utilized its anti-PD-1 therapy, KEYTRUDA®, in the INSIGHT-003 trial—which combined efti with chemotherapy—this increased clinical focus could translate into a higher volume of trials requiring MSD's anti-PD-1 therapies.

How it reaches MSD
-
Immutep announced it intends to prioritize the registration-directed clinical program for efti in patients with HNSCC. The company also stated that IMP761, an agonist anti-LAG-3 antibody, is now a co-priority alongside efti and will be presented at the American College of Rheumatology Convergence in November 2026. Additionally, Immutep received an A$0.86 million cash rebate from the Australian Government and €1.36 million from the French Government for eligible R&D activities.
The full event1independent outlet -
Immutep has previously combined efti with KEYTRUDA® in the INSIGHT-003 Phase I trial, which evaluated the combination in non-squamous 1L NSCLC. Immutep utilizes MSD's anti-PD-1 therapy and drugs in its clinical trials and operations. The expansion of Immutep's clinical focus into HNSCC suggests a sustained or increased need for the combination therapies, potentially leading to higher demand for MSD's anti-PD-1 therapies.

Why it matters
For MSD, which supplies anti-PD-1 therapies utilized by Immutep, the strategic expansion of Immutep's clinical focus represents a potential increase in the volume and duration of trials requiring their products. This could translate into a positive impact on sales and operational planning for MSD.
Immutep is actively managing its pipeline, having recently completed the INSIGHT-003 trial, which showed strong objective response rates in non-squamous 1L NSCLC. The company is also preparing for new phases of clinical trials, indicating a continued commitment to developing and testing its drug candidates in combination with established therapies.
What we don't know yet
- What specific dosage or volume of MSD's anti-PD-1 therapy will be required for the new HNSCC trials?
- Will Immutep pursue co-development or licensing agreements with MSD for the HNSCC indication?
