Tuparstobart

Clinical trials investigating Tuparstobart are studying how it performs in people with advanced cancers. The trials look at outcomes such as tumor response and progression-free survival, and they include patients with endometrial cancer and recurrent or metastatic squamous cell carcinoma of the head and neck.

Trial overview

Two authorised Phase 2 studies are investigating Tuparstobart in people with advanced cancers.[1][2] These studies are interventional, which means the research team gives study treatment and then measures how the cancer responds.[1][2]

The trials focus on different patient groups: one is for advanced or metastatic endometrial cancer after platinum-based chemotherapy, and the other is for PD-L1-positive recurrent or metastatic squamous cell carcinoma of the head and neck.[1][2]

Endometrial cancer study

The first study is the POD1UM-204 umbrella study in advanced or metastatic endometrial cancer.[1] An umbrella study is a study that looks at several treatment groups within one trial.[1]

This study includes participants who have progressed on or after platinum-based chemotherapy, which means their cancer got worse during or after treatment with a platinum medicine.[1] The study has 157 planned participants and is authorised.[1]

The main result being measured in Group A is objective response rate (ORR), which is the share of patients whose tumors have a complete response or partial response according to RECIST v1.1, a standard way to measure tumors in cancer trials.[1] Complete response means the tumor cannot be seen on scans, and partial response means the tumor has shrunk by a meaningful amount.[1]

The brief study goal is to evaluate the antitumor activity of INCMGA00012 in Group A.[1] The trial also lists other study drugs in combination arms, including Pemazyre, INCAGN02385, and INCAGN02390.[1]

Head and neck cancer study

The second study is a randomized, double-blind, multicenter Phase 2 trial in recurrent or metastatic squamous cell carcinoma of the head and neck.[2] Randomized means participants are assigned by chance to different groups, and double-blind means the patient and study team do not know which group is being given.[2]

This study is for people with PD-L1-positive disease and who are systemic therapy-naive, meaning they have not yet received body-wide treatment such as chemotherapy or immunotherapy.[2] The study plans to enroll 176 participants and is authorised.[2]

The study compares retifanlimab plus INCAGN02385, and retifanlimab plus INCAGN02385 plus INCAGN02390, against retifanlimab alone in the overall study population.[2] The brief summary says the goal is to determine the efficacy of these combinations, which means how well they work against the cancer.[2]

Study design and endpoints

The endometrial cancer study measures ORR as its primary outcome for Group A.[1] This endpoint helps show whether the treatment can shrink tumors in a meaningful way.[1]

The head and neck cancer study measures progression-free survival (PFS), which is the time from randomization until the cancer gets worse or the patient dies from any cause.[2] This endpoint helps show how long the treatment can keep the disease under control.[2]

Both studies are designed to learn more about Tuparstobart-based treatment strategies in different cancer settings, but they use different patient groups and different main outcomes.[1][2]

Who may participate

In the endometrial cancer study, the key group is people with advanced or metastatic endometrial cancer who have already had platinum-based chemotherapy and whose disease has progressed.[1]

In the head and neck cancer study, the key group is people with PD-L1-positive recurrent or metastatic squamous cell carcinoma of the head and neck who have not had systemic therapy before.[2]

These eligibility rules matter because clinical trials often focus on a specific stage of cancer or a specific test result so the results are easier to interpret.[1][2]

Glossary

  • Advanced cancer: Cancer that has grown beyond its original place or is harder to treat.
  • Metastatic: Cancer that has spread to other parts of the body.
  • Endometrial cancer: Cancer that starts in the lining of the uterus.
  • Squamous cell carcinoma of the head and neck: A type of cancer that starts in the flat cells lining the head and neck area.
  • PD-L1-positive: A test result showing that the cancer has a marker called PD-L1. This can help decide if a treatment study is suitable.
  • Systemic therapy-naive: A person has not yet received treatment that works throughout the body, such as chemotherapy or immunotherapy.
  • Platinum-based chemotherapy: A common type of cancer treatment that uses platinum medicines.
  • Phase 2: A trial stage that studies whether a treatment works in a group of patients and continues to monitor safety.
  • Randomized: Participants are assigned by chance to different treatment groups.
  • Double-blind: A study design where the patient and the study team do not know which treatment is being given.
  • Objective response rate (ORR): The percentage of patients whose tumors shrink a lot or disappear during treatment.
  • Progression-free survival (PFS): The length of time during and after treatment when the cancer does not get worse.
