to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act.
INFORMATION CONTAINED IN THIS REPORT ON FORM 6-K
On February 22, 2023, the Company issued a press release announcing its presentation at the 30th Conference on Retroviruses and Opportunistic Infections (“CROI
2023”) of initial safety and activity data from the Phase 1 portion of the Company’s Phase 1/2 clinical trial of IMC-M113V, a bispecific soluble TCR therapy built on the Company’s ImmTAX® technology which is being developed for the treatment of
people living with human immunodeficiency virus (“PLWH”). A copy of the press release is furnished as Exhibit 99.1 to this Report.
Initial Phase 1 Data of IMC-M113V STRIVE Trial Presented at the CROI 2023 Conference
The Company announced initial Phase 1 data from its first-in-human, Phase 1/2 clinical trial of IMC-M113V, which is referred to as the IMC-C103C-101 trial. The initial data was presented at CROI
2023. IMC-M113V is a new class of bispecific protein immunotherapy being developed for the treatment of patients with human immunodeficiency virus (“HIV”) infection. The trial is designed to identify a safe and biologically active dose in
HLA-A*02:01 positive PLWH receiving suppressive antiretroviral therapy for less than or equal to seven years. The secondary objectives of the trial are to characterize pharmacokinetic (“PK”) and pharmacodynamic (“PD”) profiles, including serum
cytokines (IL2, IL6, IL8, IL10, IFNγ, TNFα, and IP10) pre- and less than or equal to 24 hours post-dosing. A greater than four-fold rise in IL6 was prespecified as indicative of PD activity.
In the single ascending dose (SAD) portion of the Phase 1 clinical trial, three dose levels of IMC-M113V, given as a single IV infusion, were evaluated: a starting dose of 1.6 mcg, based on the
minimum anticipated biological effect level (n=1), 5 mcg (n=1) and 15 mcg (n=10). All doses were observed to be well tolerated. There were no serious adverse events observed, nor any significant changes in hematology or chemistry. There were also
no reports of cytokine release syndrome or neurotoxicity.
Plasma viral load remained suppressed throughout trial dosing and follow-up. In addition, transient, dose-dependent increases in serum IL6 occurred eight-24 hours post-infusion. Five out of the ten
participants in the trial who received the 15-mcg dose showed a greater than 4-fold rise in IL6, which had been prespecified as indicative of pharmacodynamic activity based on prior experience from clinical trials with the Company’s approved
product, KIMMTRAK (tebentafusp).
Patient enrollment in the multiple ascending dose (MAD) portion of the trial has started, and the Company plans to enroll up to 28 participants with PLWH.
Also on February 22, 2023, the Company updated its corporate presentation with the slides reflecting the data presented at CROI 2023. The updated corporate presentation is available in
the “Investors/Media” section of the Company’s website at www.immunocore.com. The Company intends to use this presentation in meetings with analysts, investors and others from time to time. A copy of
the new slides added to the corporate presentation is being furnished as Exhibit 99.2 to this Report.
