On November 25, 2024 Astrazeneca reported that positive high-level results from the CAPItello-281 Phase III trial showed Truqap (capivasertib) in combination with abiraterone and androgen deprivation therapy (ADT) demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of radiographic progression-free survival (rPFS) versus abiraterone and ADT with placebo in patients with PTEN-deficient de novo metastatic hormone-sensitive prostate cancer (mHSPC) (Press release, AstraZeneca, NOV 25, 2024, View Source [SID1234648601]).

Overall survival (OS) data were immature at the time of this analysis; however, the Truqap combination showed an early trend towards an OS improvement versus abiraterone and ADT with placebo. The trial will continue as planned to further assess OS as a key secondary endpoint.

Prostate cancer is the second most prevalent cancer in men and the fifth leading cause of male cancer death globally.1 Only one third of patients with metastatic prostate cancer survive five years after diagnosis.2 Newly diagnosed mHSPC is an aggressive form of the disease associated with poor outcomes and survival.3,4 Approximately 200,000 patients are diagnosed with mHSPC each year, and one in four have PTEN-deficient tumours.5 Patients with a tumour biomarker of PTEN deficiency have a particularly poor prognosis.6

Karim Fizazi, MD, PhD, Institut Gustave Roussy, and University of Paris Saclay in Villejuif, France, and principal investigator for the trial said: "Patients with this aggressive form of prostate cancer with tumour PTEN deficiency currently face a particularly poor prognosis, and there is an urgent need for new treatments that improve upon current therapies. The results seen with capivasertib in combination with abiraterone-prednisone and androgen deprivation therapy in the CAPItello-281 trial represent a step forward for these patients."

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: "These results show for the first time, that adding an AKT inhibitor to a standard-of-care therapy can provide benefit to patients with a biomarker of PTEN-deficient metastatic hormone-sensitive prostate cancer. By targeting a key driver of the disease, we have been able to improve upon current therapies and demonstrate the potential role of this combination in an area of critical unmet need. It will be important to see greater maturity in key secondary endpoints including overall survival."

The safety profile of Truqap in combination with abiraterone and ADT in CAPItello-281 was broadly consistent with the known profile of each medicine.

Data will be presented at a forthcoming medical meeting and shared with global regulatory authorities.

Notes

Prostate cancer
Prostate cancer is the second most prevalent cancer in men and the fifth leading cause of male cancer death globally, with an incidence of more than 1.4 million and approximately 397,000 deaths in 2022.1

Metastatic prostate cancer is associated with a significant mortality rate, with only one third of patients surviving five years after diagnosis.2 Development of prostate cancer is often driven by male sex hormones called androgens, including testosterone.7

Metastatic hormone-sensitive prostate cancer
In patients with mHSPC, also known as metastatic castration-sensitive prostate cancer (mCSPC), prostate cancer cells need high levels of androgens to drive cancer growth.4,7 Hormone therapies, such as ADT, are widely used to block the action of male sex hormones and lower the levels of androgens in the body.4,8 However, resistance to these therapies is common and there is a need to extend their use to delay disease progression and castration resistance, where the prostate cancer grows and spreads to other parts of the body despite the use of these therapies.3,4,8

In patients with de novo mHSPC, the cancer has spread to distant parts of the body at the time of first diagnosis.9

PTEN-loss or deficiency fuels the growth of cancer cells, leading to dysregulation of the PI3K/AKT pathway, and is associated with poor outcomes in patients with prostate cancer.6,10

CAPItello-281
CAPItello-281 is a Phase III, double-blind, randomised trial evaluating the efficacy and safety of Truqap in combination with abiraterone and ADT versus abiraterone and ADT in combination with placebo in the treatment of patients with PTEN-deficient de novo mHSPC.

The global trial enrolled 1,012 adult patients with histologically confirmed de novo hormone-sensitive prostate adenocarcinoma and PTEN deficiency as confirmed by central testing. The primary endpoint of the CAPItello-281 trial is rPFS as assessed by investigator, with OS as a secondary endpoint.

Truqap
Truqap is a first-in-class, potent, adenosine triphosphate (ATP)-competitive inhibitor of all three AKT isoforms (AKT1/2/3). Truqap 400mg is administered twice daily according to an intermittent dosing schedule of four days on and three days off. This was chosen in early phase trials based on tolerability and the degree of target inhibition.

Truqap is approved in the US, EU, Japan and several other countries for the treatment of adult patients with HR-positive (or ER-positive), HER2-negative locally advanced or metastatic breast cancer with one or more biomarker alterations (PIK3CA, AKT1 or PTEN) following recurrence or progression on or after an endocrine-based regimen based on the results from the CAPItello-291 trial. Truqap is also approved in Australia for the treatment of adult patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer following recurrence or progression on or after an endocrine based regimen based on these trial results.

Truqap is currently being evaluated in Phase III trials for the treatment of breast cancer (CAPItello-292) and prostate cancer (CAPItello-280 and CAPItello-281) in combination with established treatments.

Truqap was discovered by AstraZeneca subsequent to a collaboration with Astex Therapeutics (and its collaboration with the Institute of Cancer Research and Cancer Research Technology Limited).

On November 25, 2024 Rakovina Therapeutics Inc. (TSX-V: RKV) ("Rakovina" or the "Company"), a biopharmaceutical company committed to advancing new cancer therapies based on novel DNA-damage response targeting technologies, reported the presentation of a poster showcasing initial results of its Deep Docking Artificial Intelligence (AI) drug discovery screening at the 29th Annual Meeting and Education Day of the Society for Neuro-Oncology (SNO), which was held November 21-24 in Houston, TX (Press release, Rakovina Therapeutics, NOV 25, 2024, View Source;utm_medium=rss&utm_campaign=rakovina-therapeutics-presents-ai-driven-drug-discovery-research-at-society-for-neuro-oncology-annual-meeting [SID1234648617]).

The poster, titled "Utilizing Artificial Intelligence for the Discovery of Novel PARP1-Selective Inhibitors for Use Against Brain Tumors," highlighted a rapid virtual multi-billion compound screen to identify selective inhibitors of PARP-1, a key enzyme involved in DNA repair that plays a critical role in brain cancer progression. Inhibition of PARP-1 has shown promise in sensitizing cancer cells to treatment.

The poster provided insight into the compounds’ chemical properties affecting absorption, stability, and the ability to cross the blood-brain barrier. The poster also profiled candidates that are predicted to have similar or improved PARP-1 selectivity and central nervous system (CNS) exposure compared with AZD9574, a novel development-stage blood-brain barrier penetrant and selective inhibitor of PARP-1.

"Our team reached a significant milestone this fall with the initial results of our Deep Docking AI screening efforts, successfully evaluating billions of molecular structures within the projected timeframe described at the outset of the collaboration," said Jeffrey Bacha, Executive Chairman of Rakovina Therapeutics. "We were thrilled to present these preliminary findings to leading brain cancer researchers, clinicians, and potential pharmaceutical partners at the prestigious SNO conference. Our poster highlighted the transformative power of AI in accelerating the discovery of potential best-in-class drug candidates."

"Our innovative approach is not only improving the efficiency of drug discovery, but it is also enhancing the specificity and efficacy of potential therapeutics. Our novel class of PARP-1 selective inhibitors can offer hope for more effective treatments in the fight against primary brain tumors and cancers that have metastasized to the brain," he added. "The next step is to select a lead candidate molecule based on wet lab validation for target selectivity, metabolic and pharmacokinetic parameters, CNS penetration, and activity against cancer."

First-generation poly (ADP-ribose) polymerase (PARP) inhibitors have dramatically improved patient outcomes in certain mutated cancers but are limited in their utility to treat brain malignancies as they cannot pass through the blood-brain barrier. They also have adverse side effects that are possibly driven by the collateral inhibition of PARP-2. The successful development of a PARP-1 selective CNS penetrant inhibitor could reduce toxicity while providing a new therapeutic option for brain tumors.

Upcoming Video Conference Call

Rakovina Therapeutics will host a video conference call on Wednesday, November 27, 2024, at 10 am PST to further discuss the data presented at the Society for Neuro-Oncology Annual Meeting and discuss next steps and upcoming milestones in the PARP inhibitor and other development programs.

"We are proud to share this new data on Signatera at SABCS that underscores our commitment to generating evidence on the clinical utility of Signatera for patients with breast cancer," said Angel Rodriguez, M.D., senior medical director at Natera.

The full list of abstracts with selected highlights are as follows:

ZEST Clinical Trial
Oral Presentation #GS3-01 | Dec. 13 | Presenter: Nicholas Turner, MD, PhD, FRCP, FMedSci
Circulating tumor DNA surveillance in ZEST, a randomized, phase 3, double-blind study of niraparib or placebo in patients with triple-negative breast cancer or HR+ HER2− BRCA-mutated breast cancer with molecular residual disease after definitive therapy

ZEST was a randomized, phase III, double-blind trial, sponsored by GSK, that evaluated whether niraparib can enhance disease-free survival in patients with breast cancer who are ctDNA-positive after completion of curative intent therapy and without evidence of radiographic recurrence. A total of 2,746 patients were pre-screened. Of patients who were ctDNA-positive, 40 were enrolled and randomized (niraparib, 18; placebo, 22); 36 patients (90%) had Triple Negative Breast Cancer (TNBC), and 4 patients (10%) had BRCA-mutated HR+ disease. An analysis of outcomes among randomized patients showed a median disease-free survival of 11.4 months in the niraparib arm versus 5.4 months in the placebo group (hazard ratio, 0.64; 95% CI, 0.30–1.39).

Clinical Genomics Database Experience
Poster Spotlight #PS9-01 | Dec. 12 | Presenter: Marla Lipsyc-Sharf, MD
Actionable Genomic Alterations in Localized Hormone Receptor Positive (HR+) Breast Cancer and Impact on Clinical Outcomes: Results from Comprehensive Whole Exome Sequencing (WES) and Tumor-Informed circulating tumor DNA (ctDNA) analysis

This real-world analysis evaluated the association of targetable tumor genomic alterations with ctDNA detection and distant recurrence-free survival (DRFS) in early-stage breast cancer. In the study, 44% of patients (127/287) who were Signatera-positive had at least one targetable genomic alternation, including 34.5% with the PIK3CA mutation. In addition, of patients with ctDNA-positivity within 2 years, those with mutated PIK3CA had an inferior DRFS (HR: 36.9), compared to patients with wild-type PIK3CA (HR=16.3).

Patient-Reported Outcomes
Four abstracts to be presented at SABCS evaluated patient reported outcomes when testing for circulating tumor DNA (ctDNA). The data indicates that ctDNA testing can provide valuable information for treatment planning while not causing increased anxiety in patients.
