ENGAGER-PSMA-01 is a first-in-human, open-label, multicenter Phase 1 clinical trial designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of JANX007 administered as monotherapy or in combination in adult patients with advanced metastatic castration-resistant prostate cancer (mCRPC).

In December 2024, Janux reported positive interim clinical data from the Phase 1a dose escalation portion of the trial in 16 mCRPC patients with a median of four prior lines of therapy. At that time, the median radiographic progression-free survival (rPFS) reported was 7.4 months for all 16 patients.* As of April 21, 2025, updated results** have been achieved in the same 16 patients supporting the initiation of the Phase 1b expansion studies:

Median rPFS of 7.5 months (n=16)
Median rPFS of 7.9 months for patients treated at 6mg and 9mg target doses (n=9)
6-month rPFS of 65% (n=16)
6-month rPFS of 78% for patients treated at 6mg and 9mg target doses (n=9)
Safety data remained consistent with the December 2024 data disclosure (n=16)
*8/16 patients were noted as in-progress in the December 2024 reported results.
**rPFS results based upon Kaplan-Meier estimate.

In addition, Janux has selected a CRS-mitigation strategy to support the initiation of the Phase 1b expansion studies that is designed to maintain the CRS profile reported in December.

The first Phase 1b expansion study will enroll taxane-naïve mCRPC patients and is designed to generate additional safety and efficacy data in this first and second line (1L/2L) patient population. This study will assess JANX007 monotherapy at two dose regimens (0.3/2/6mg and 0.3/2/9mg) with dosing administered once weekly or once every two weeks in mCRPC patients who have progressed on or after novel hormonal therapy (NHT).

"Initiation of the taxane-naïve study marks an important step as we begin to evaluate JANX007 in earlier-line mCRPC patient populations," said Zachariah McIver, D.O., Ph.D., Chief Medical Officer of Janux. "While therapeutic options for mCRPC have expanded, there remains a significant need for novel, non-chemotherapeutic approaches."

Janux plans to initiate three additional Phase 1b expansion studies, evaluating:

JANX007 in combination with an androgen receptor inhibitor in taxane-experienced mCRPC patients
JANX007 monotherapy in PARP inhibitor-resistant mCRPC patients
JANX007 monotherapy in NHT- and taxane-experienced mCRPC patients designed to support OPTIMUS dose selection for registrational studies
"Improved efficacy and durability of responses has been observed by other prostate cancer drugs and TCEs when moving into earlier lines of therapy. There are also indications that safety with TCEs improve in earlier lines of therapy where disease burden is lower. We believe that these observations, coupled with the data seen in our Phase 1a dose escalation in later line patients, strongly support our decision to develop JANX007 in earlier lines of therapy," said David Campbell, Ph.D., President and CEO of Janux.

Additional data from JANX007 and JANX008 will be presented at future Janux events in the second half of 2025. Separately, Janux will host an R&D Day in mid-2025 highlighting product candidates identified from its preclinical pipeline to move into clinical trials.

With evaluation of approximately 200 patients and more than 2,100 plasma samples across multiple distinct subtypes, this is the largest sarcoma cohort to date using personalized circulating-tumor DNA (ctDNA) monitoring. The study assessed the correlation of Signatera results with imaging, stratified by sarcoma subtype, and followed patients through treatment, disease progression, and surveillance.

Key findings included:

The results demonstrated excellent test performance, with overall sensitivity to recurrence of 89% and specificity of 100%.
In leiomyosarcoma, the most common subtype in the cohort, sensitivity was 93%, with specificity of 100%.
For leiomyosarcoma patients who experienced progression, ctDNA kinetics during subsequent therapy were highly correlated with treatment response (90%).
Sarcomas are a heterogeneous group of rare cancers, with more than 70 distinct histologic subtypes1, making treatment response and recurrence especially difficult to monitor through standard imaging and clinical evaluation. There are approximately 17,000 new cases of sarcoma diagnosed annually in the United States.2

"This data represents a major step forward in understanding how ctDNA monitoring can be applied across a diverse range of sarcoma subtypes," said Beatrice J. Sun, M.D., department of surgery at Stanford University. "With the ability to noninvasively detect disease recurrence and monitor treatment response, Signatera demonstrates the potential to meaningfully improve personalized care for patients with sarcoma."

"This is the most comprehensive dataset to date on ctDNA monitoring in sarcoma, and it shows excellent performance of Signatera in a difficult-to-monitor cancer," said Alexey Aleshin, M.D., corporate chief medical officer and general manager of oncology at Natera. "The heterogeneity of sarcoma demands a personalized approach, and these results support Signatera’s unique ability to track disease status with precision across a broad spectrum of subtypes."

This retrospective real-world study demonstrates the promise of Signatera as a tool to monitor disease recurrence and treatment response. To build on these findings, the team intends to launch a prospective study to further demonstrate Signatera’s clinical utility and explore its role in informing treatment decisions and improving future sarcoma care.

Strategic Trial Design to Address Critical Treatment Gap in TNBC

The innovative dual-approach in the clinical trial is designed to evaluate LP-184 in recurrent, advanced-stage TNBC patients through:

Monotherapy Arm: An open-label study involving approximately 30 patients with advanced-stage TNBC, focusing on dose optimization to evaluate, enhance and optimize safety and potential efficacy for TNBC patients.
Combination Therapy: Evaluation of LP-184 in combination with olaparib in second-line settings for patients with advanced-stage TNBC harboring BRCA1 or BRCA2 alterations, with primary endpoints including safety and efficacy parameters that could potentially support a pathway to regulatory approval.
This strategic approach focuses on addressing a significant unmet medical need, with average survival for newly diagnosed metastatic TNBC estimated at 10 to 18 months, representing an annual market opportunity exceeding $4 billion USD.

LP-184 Background in TNBC & Mechanistic Rationale

LP-184 is a synthetically lethal small molecule that induces DNA double strand breaks upon bioactivation by the enzyme prostaglandin reductase 1 (PTGR1) in cancer cells. Preclinical studies and artificial intelligence-driven in silico modeling suggest that cancers with DDR gene alterations may preferentially respond to LP-184.2

Preclinical findings also suggest that LP-184 is particularly well positioned for TNBC with striking data from in vivo models including complete regression seen in several PARP resistant as well as PARP sensitive PDXs (see Figure 1).

Nearly 70% of TNBCs are noted to harbor deficiency in homologous recombination pathways, making them likely to be particularly sensitive tumors for targeting with drug-candidate LP-184. In addition, it is estimated that up to 46% percent of women with TNBC will develop brain metastasis3, and LP-184 has shown blood brain barrier (BBB) penetration, with evidence of activity in preclinical brain metastasis models.

LP-184 Phase 1b/2 TNBC Trial Overview – Monotherapy

The monotherapy phase 1b/2 trial is designed to evaluate LP-184 in patients with advanced-stage TNBC. The study is designed to focus on dose optimization to evaluate and enhance both safety and potential efficacy ultimately aiding in the potential determination of the best clinical position for LP-184 in advanced-stage TNBC patients. The design of the dose optimization phase, provides for evaluation of the safety, efficacy and pharmacokinetics of LP-184 using 2 dose levels in an open-label monotherapy study involving around 30 patients to be dosed with LP-184.

LP-184 Phase 1b/2 TNBC Trial Overview – Combination Therapy with PARP inhibitor

LP-184 has also been shown in preclinical studies to be highly potent in combination with the PARP inhibitor, olaparib, including in tumors that are resistant to PARP inhibitors. In preclinical studies, treatment of a HBCx-28 TNBC PDX model, with BRCA-1 LOH and an HRD score of 63 that was resistant to the PARP inhibitor, showed evidence of re-sensitization in combination with LP-184 (See Figure 2). These data, which were initially presented at the San Antonio Breast Cancer Symposium, support the clinical evaluation of LP-184 in combination with PARPi in an earlier line of treatment. Treating patients in an earlier clinical setting has the potential to reach more patients and potentially generate a more durable and deeper earlier control of the disease.

The design of the combination phase 1b/2 trial provides for LP-184 to be evaluated in a second-line setting in patients with advanced-stage TNBC whose primary tumor harbors alterations in BRCA1 or BRCA2. The primary end points of the study are expected to include safety and efficacy, with the aim of supporting a potential pathway to a regulatory approval process.

Multi-Region Clinical Strategy with Focus on High-Incidence Countries

The trials are planned to be conducted at select centers in the United States as well as academic cancer centers and institutions in India and Nigeria, where TNBC incidence rates are particularly high—comprising nearly 40% of initial breast cancer diagnoses. This strategic site selection is focused on leveraging established collaborative research networks that have a track record of successful collaborative cancer studies with US and European pharma companies. Lantern’s planned objective will be to ensure proper local experience and support for this clinical trial while addressing regions with significant disease burden and high clinical demand.

"This IND clearance for LP-184 in a Phase 1b/2 study represents a pivotal advancement in our mission to bring precisely targeted, AI-developed medicines to patients with aggressive cancers and limited treatment options," said Panna Sharma, CEO and President of Lantern Pharma. "The strategic design of our clinical program reflects both the compelling mechanistic rationale and the encouraging data supporting LP-184’s potential in TNBC."

Expanding Therapeutic Potential Across Multiple Indications

Beyond TNBC, LP-184 shows promise for the potential treatment of other cancers harboring DNA damage repair mutations, including lung, bladder, pancreatic, and ovarian cancers. Additional clinical trials in these targeted indications are in planning stages, with several being considered as Investigator Initiated Trials. LP-184 has received multiple Orphan Drug, Fast Track, and Rare Pediatric Disease Designations from the FDA across various solid tumor indications.

The global TNBC market is estimated at $3-5 billion USD annually, with over 300,000 new cases diagnosed worldwide each year. While homologous recombination deficient TNBCs are often initially treated with PARP inhibitors, resistance inevitably develops, underscoring the critical need for novel therapeutic approaches.

Immorta Bio is the first company to develop a "senolytic immunotherapy" for treatment of cancer and aging. This treatment comprises of training the immune system of patients to selectively kill "senescent cells" that promote aging and act as a shield to protect cancer against immune responses. By removing this defense mechanism, cancer becomes susceptible to immune attack.

The Company has shown that its lead senolytic immunotherapy product, SenoVax, is capable of destroying lung, breast, pancreatic and brain cancers, as well as melanoma3 in animal models.

"Having been chosen to present our work on using the immune system to fight cancer and aging in such an esteemed panel is truly an honor," said Dr. Thomas Ichim, President and Chief Scientific Officer of Immorta Bio.

T cell mediated mechanisms of how SenoVax enables its anticancer effects have previously been published in the peer-reviewed literature with collaborators at University of California San Diego, Georgetown University, Ceders Sainai, and Calidi Bio4. Additionally, the Company recently demonstrated that natural killer cell activation as a result of SenoVax therapy also plays a role in stimulation of cancer destruction5.

"We have founded Immorta Bio on the principle of ‘Scientific’ Longevity," said Dr. Boris Reznik, President and CEO of Immorta Bio. "There is no better validation of our science than to be chosen to give an oral presentation at such a prestigious and exclusive scientific gathering as AAI2025."
