GOSH operates specialised manufacturing facilities for research and development of cell and gene therapies. This includes clean-room laboratories, storage and specialist training facilities. Under the terms of the agreement GOSH will work with Leucid at the state-of-the-art cleanroom facilities at the Zayed Centre for Research into Rare Disease in Children and provide quality assurance services required for manufacture of clinical product for the LEU011 first-in-man study, and potentially, other Leucid clinical programmes.

Each Party will retain ownership of background IP and Leucid (subject to contractual obligations) will own all Intellectual Property Rights arising from the Manufacturing Services performed.

Ian Miscampbell, Interim Executive Chairman of Leucid Bio, said: "We are extremely pleased to enter this first-of-its-kind agreement with GOSH to manufacture our lead asset, LEU011, for use in human studies. Additionally, we are pleased to have started a process with GOSH to examine the feasibility of applying our approach in the paediatric setting where there remains a great unmet need for new therapies. Working in close collaboration with leading institutes such as GOSH is fundamental to our ability to move quickly into clinical trials, using their state-of-the-art manufacturing facilities based here in London."

Stephen Mathew, Head of Innovation at GOSH said: "Gene and cell therapies are the cutting-edge in clinical research, holding promise to offer personalised cancer treatment, including for rare forms that affect children and young people. At Great Ormond Street Hospital, we see children with the most rare and complex cancers. There have been incredible strides forward in the treatments that we can offer, however, sadly for many these still don’t work. Gene and cell therapies offer hope for better, and potentially curative treatments which is why we’re excited to support innovation in gene therapies through access to these highly specialist and unique facilities."

CAR T-cell therapy is revolutionary technology in which immune cells, called T-cells, are reprogrammed so they can recognise and destroy cancer cells. This has proven to be a powerful therapy for refractory blood cancers but to date has lacked efficacy for the treatment of solid cancers.

Leucid Bio has developed two proprietary platforms that build upon Dr Maher’s novel ‘lateral’ CAR-T model which develops CAR-T molecules designed to adopt a more natural configuration within the T-cells. The technology gives properties to the CAR-Ts that enable them to consistently outperform previous generations of CAR-T therapies in pre-clinical studies; enhancing T-cell potency and generating a persistent long-term response with reduced toxicity.

LEU011 is based on a novel lateral CAR structure, in which complementary signalling domains are integrated in parallel across the cell membrane. This formation replicates the natural side-by-side position of these molecules across the cell membrane that is seen in endogenous immune receptors.

Previous pre-clinical studies have shown that LEU011 consistently outperforms previous generations of CAR T-cells in those studies, enabling better control over T-cell activation, superior anti-tumour activity, and a favourable toxicity profile.

About ST101

ST101, a first-in-class antagonist of C/EBPβ, is currently being evaluated in the Phase 2 portion of an ongoing Phase 1-2 clinical study in patients with advanced unresectable and metastatic solid tumors (NCT04478279). ST101-101 is an open-label, Phase 1-2 dose-finding study designed to determine the safety, tolerability, PK, PD, and proof-of-concept efficacy of ST101 in patients with advanced solid tumors. The study consists of two phases: Phase 1 dose escalation/regimen exploration and Phase 2 dose expansion. In the ongoing Phase 2 dose expansion, Sapience is actively enrolling patients with GBM, metastatic cutaneous melanoma, castration-resistant prostate cancer and locally advanced or metastatic hormone-receptor positive breast cancer. In the ongoing dose escalation part of the study, ST101 has demonstrated clinical proof-of-concept with a durable RECIST 1.1-confirmed partial response (PR) in a patient with cutaneous melanoma and evidence of long-lasting stable disease in several additional patients. In the ongoing Phase 2 dose expansion part of the study, ST101 has demonstrated clinical proof-of-concept with a mRANO-confirmed partial response in a patient with recurrent GBM and evidence of long-lasting stable disease in several additional patients.

ST101 has been granted Fast Track designation for recurrent GBM and advanced cutaneous melanoma in patients who have disease progression on or after anti-PD-1/anti-PD-L1 therapy, as well as orphan designations from the FDA for advanced melanoma, glioma and AML, and from the European Commission for the treatment of glioma.

About ST316

ST316, a first-in-class β-catenin antagonist, is in Phase 1 clinical development following the clearance of its Investigational New Drug (IND) application by the U.S. Food and Drug Administration in March 2023. β-catenin is a critical member of the canonical Wnt signaling pathway, a well-known development stage pathway that has been considered an "undruggable" cancer target, as small molecules have proven ineffective or toxic. Preventing β-catenin translocation to the nucleus through disruption of the interaction between BCL9 and β-catenin allows for disruption of oncogenic WNT-signaling, resulting in tumor cell death and a pro-inflammatory tumor microenvironment – without disruption of homeostatic WNT-function. ST316 suppresses transcription of Wnt target genes regulating proliferation, migration, invasion and the metastatic potential of tumor cells, as well as genes regulating the immunosuppression of the tumor microenvironment.

In preclinical studies, ST316 was well tolerated and demonstrated significant in vitro and in vivo anti-tumor activity. Sapience expects to begin patient dosing in the Phase 1 dose escalation portion of the Phase 1-2 study in the first half of 2023.

FDA Approves Expanded Indication for Telix’s Illuccix® to Include Patient Selection for PSMA-Directed Radioligand Therapy

On March 16, 2023 Telix Pharmaceuticals Limited (ASX: TLX, Telix, the Company) reported that the United States Food and Drug Administration (FDA) has approved a supplementary New Drug Application (sNDA) for Illuccix (kit for the preparation of gallium Ga 68 gozetotide injection) to enable its use for the selection of patients with metastatic prostate cancer, for whom 177Lu 177 PSMA-directed therapy is indicated (Press release, Telix Pharmaceuticals, MAR 16, 2023, View Source [SID1234628961]).

The label expansion means Illuccix is now approved in the U.S. to select patients who are candidates for the only FDA-approved prostate-specific membrane antigen (PSMA)- directed radioligand therapy (Pluvicto),[2] providing doctors with critical information to help optimize and guide treatment decisions. To qualify for radioligand therapy, patients must be imaged with an approved gallium-based PSMA-PET agent.[3]

As the only diagnostic agent for suspected metastatic and recurrent prostate cancer that combines the accuracy of gallium imaging with the reliability and flexibility of Telix’s distribution network, the expanded indication for Illuccix has the potential to improve access to imaging for patients who are candidates for radioligand therapy.

Kevin Richardson, Chief Executive Officer for Telix Americas said, "We welcome the FDA’s decision to expand the label indication for Illuccix. This additional indication further demonstrates our continued commitment to support patients fighting prostate cancer and to empower the doctors who treat them. Clinicians now have the ability to use Illuccix in more stages of the patient journey, to confidently and accurately detect and help manage this disease."

Use of Illuccix in the VISION Phase III study (ClinicalTrials.gov Identifier: NCT03511664)[4] helped doctors detect prostate cancer and identify the appropriate patients for PSMA-based radioligand therapy. Telix wishes to acknowledge collaboration with Novartis to deliver this outcome to patients.

Dr Oliver Sartor, Medical Director at Tulane Cancer Center, added, "As radioligand therapy for prostate cancer becomes more prevalent, it is critical for doctors to understand who may or may not respond to those treatments. There’s no doubt that appropriate selection of patients for PSMA targeted radioligand therapy is dependent on appropriate imaging. Ga-68 PSMA-11 PET was used in the VISION trial and, when used in combination with contrast-enhanced CT, represents a powerful tool for detecting prostate cancer and helping guide patient management."

It is estimated that 32,000 patients per year in the U.S. may be considered for PSMA-directed radioligand therapy.[5]

INDICATIONS AND USAGE

ILLUCCIX, after radiolabeling with Ga 68, is for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer:

With suspected metastasis who are candidates for initial definitive therapy
With suspected recurrence based on elevated serum prostate-specific antigen (PSA) level
For selection of patients with metastatic prostate cancer, for whom lutetium Lu 177 vipivotide tetraxetan PSMA-directed therapy is indicated.
IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Risk for Misinterpretation

Image interpretation errors can occur with ILLUCCIX PET. A negative image does not rule out the presence of prostate cancer, and a positive image does not confirm the presence of prostate cancer. Gallium Ga 68 gozetotide uptake is not specific for prostate cancer and may occur with other types of cancer as well as non-malignant processes such as Paget’s disease, fibrous dysplasia, and osteophytosis. Clinical correlation, which may include histopathological evaluation of the suspected prostate cancer site, is recommended.

Imaging Prior to Initial Definitive or Suspected Recurrence Therapy

The performance of ILLUCCIX for imaging of biochemically recurrent prostate cancer seems to be affected by serum PSA levels and by site of disease. The performance of ILLUCCIX for imaging of metastatic pelvic lymph nodes prior to initial definitive therapy seems to be affected by Gleason score.

Imaging to Select Patients for Lutetium Lu 177 Vipivotide Tetraxetan Therapy

The interpretation of ILLUCCIX PET may differ depending on imaging readers. ILLUCCIX PET interpretations to select patients for lutetium Lu 177 vipivotide tetraxetan therapy may be more consistent when judging gallium Ga 68 gozetotide uptake in any one tumor lesion compared to judging uptake for all lesions larger than size criteria. Multidisciplinary consultation to select patients for lutetium Lu 177 vipivotide tetraxetan therapy is recommended, particularly for ILLUCCIX imaging that a single reader finds borderline or difficult to interpret, or when patient eligibility hinges only on judgment of gallium Ga 68 gozetotide uptake for all lesions larger than size criteria.

Radiation Risks

Gallium Ga 68 gozetotide contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. Ensure safe handling to minimize radiation exposure to the patient and healthcare providers. Advise patients to hydrate before and after administration and to void frequently after administration.

ADVERSE REACTIONS

The safety of gallium Ga 68 gozetotide was evaluated in 960 patients in the PSMA-PreRP and PSMA-BCR studies, each receiving one dose of gallium Ga 68 gozetotide. The average injected activity was 188.7 ± 40.7 MBq (5.1 ± 1.1 mCi). The most commonly reported adverse reactions were nausea, diarrhea, and dizziness, occurring at a rate of <1%.

In the VISION study, 1003 patients received one dose of gallium Ga 68 gozetotide intravenously with the amount of radioactivity 167.1 ± 23.1 MBq (4.52 ± 0.62 mCi). Adverse reactions occurring at ≥0.5% in patients with metastatic prostate cancer who received gallium Ga 68 gozetotide injection in the clinical study were fatigue (1.2%), nausea (0.8%), constipation (0.5%), and vomiting (0.5%).

Adverse reactions occurring at a rate of < 0.5% in the VISION study were diarrhea, dry mouth, injection site reactions, including injection site hematoma and injection site warmth and chills.

DRUG INTERACTIONS

Androgen deprivation therapy and other therapies targeting the androgen pathway

Androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, can result in changes in uptake of gallium Ga 68 gozetotide in prostate cancer. The effect of these therapies on performance of gallium Ga 68 gozetotide PET has not been established.
