Frequently asked questions about IBRX-042

What is IBRX-042 used for?

IBRX-042 is an investigational therapy being studied in adults with HPV-related carcinoma, a group of cancers associated with human papillomavirus infection. It is in Phase 1 clinical development in the United States. The trial enrolls participants 18 years and older and is not currently recruiting new participants.

What does IBRX-042 target?

IBRX-042 targets the HPV E6 and E7 proteins. These viral proteins are expressed in HPV-associated tumors, and the candidate is designed to direct an immune response against cells expressing them. The trial is biomarker-selected, meaning participants are chosen based on characteristics related to the target.

Who is developing IBRX-042?

IBRX-042 is being developed by ImmunityBio, Inc., which trades on the Nasdaq under the ticker IBRX. The company is running the Phase 1 study of the candidate in HPV-associated tumors in the United States.

What phase is IBRX-042 in?

IBRX-042 is in Phase 1 clinical development. It is investigational and has not been approved by the FDA. The single Phase 1 trial, NCT05976828, is active but no longer recruiting, with an planned enrollment of 12 participants.

What clinical trials is IBRX-042 in?

IBRX-042 is being studied in one clinical trial, NCT05976828, titled "IBRX-042 In Participants With HPV-Associated Tumors." The Phase 1 study is active but not recruiting, enrolls 12 participants, is controlled, and is open to all sexes aged 18 years and older.

Is IBRX-042 the same as the hAd5-HPV Vaccine?

Yes. IBRX-042 is also known as the hAd5-HPV Vaccine, and the two names refer to the same investigational candidate. It is being developed by ImmunityBio for HPV-related carcinoma and is currently in Phase 1 testing.
