H.C. Wainwright & Co. acted as the exclusive placement agent for the offering.

The aggregate gross proceeds to the Company from this financing were $1.83 million, before deducting the placement agent fees and other offering expenses payable by the Company. The total gross proceeds raised by the Company in registered direct offerings and concurrent private placements since the beginning of December 2024 are approximately $9.15 million, before deducting placement agent fees and other offering expenses payable by the Company. Additional gross proceeds of approximately $2.9 million were raised from the exercise of warrants previously issued on July 12, 2024 having an exercise price of $5.45 per share.

Phio intends to use the net proceeds from these financings for working capital and other general corporate purposes, including to fund the remaining clinical activities for Phio’s Phase 1b clinical trial of its lead product candidate, PH-762, for the treatment of patients with cutaneous squamous cell carcinoma, melanoma and Merkel cell carcinoma. Phio expects that the proceeds will allow it to continue development activities on its second clinical target, PH-894, which silences the BRD4 protein implicated in a number of solid tumors.

"Procurement of these funds provides a financial pathway to realizing the completion of the PH-762 Phase 1b clinical trial, a critical milestone for the development program," commented Robert Bitterman, Phio President and CEO. "We are also excited to be able to move the PH-894 program forward."

The obtained data provides valuable insight into using the onco-fetal Chondroitin Sulfate (ofCS) binding Vartumab to selectively target tumors (Nat Commun. 2024 Aug 30;15(1):7553). The study will in total include 16 patients with various solid cancer types for each of the two Vartumab antibodies. Allowing the research team to evaluate the biodistribution and tumor accumulation of both Vartumabs prior to clinical testing of Vartumab-based Antibody Drug Conjugates (ADC).

"The enrollment of the first patient is always a big milestone in clinical research. Our team is very happy with the first patient-in and we’re excited to gather more data on the Vartumabs." – Noortje van Dijk, project manager at TRACER.

"I am thrilled to see our new pan-cancer antibodies moving forward in this first clinical study, paving the way for efficacy studies and hopefully one day a novel treatment for the many cancer patients with limited or exhausted clinical options" – Ali Salanti, CEO at VAR2 Pharma.

Replimune Announces Biologics License Application Acceptance and Priority Review for RP1 for the Treatment of Advanced Melanoma

On January 21, 2025 Replimune Group, Inc. (NASDAQ: REPL), a clinical stage biotechnology company pioneering the development of novel oncolytic immunotherapies, reported that the U.S. Food and Drug Administration (FDA) has accepted the Biologics License Application (BLA) for RP1 (vusolimogene oderparepvec) in combination with nivolumab for patients with advanced melanoma (Press release, Replimune, JAN 21, 2025, View Source [SID1234649796]). The FDA granted the BLA Priority Review with a Prescription Drug User Fee Act (PDUFA) action date of July 22, 2025. The FDA also informed the Company that they are not currently planning to hold an advisory committee meeting in relation to this application, and at this time have not identified any potential review issues. The BLA is supported by the primary analysis data of the IGNYTE trial, evaluating RP1 combined with nivolumab in patients with anti-PD-1 failed melanoma. A confirmatory Phase 3 trial, IGNYTE-3, is currently underway with over 100 sites planned globally.

"There are limited treatment options and a significant unmet need for patients with advanced melanoma who previously received an anti-PD-1 containing regimen," said Sushil Patel, Ph.D., Chief Executive Officer, Replimune. "The BLA acceptance is an important milestone for Replimune, and we look forward to working closely with the FDA on the review of our application."

The FDA grants Priority Review to applications for medicines that, if approved, provide significant improvements in the safety or effectiveness of the treatment of a serious condition. Recently, Replimune received Breakthrough Therapy designation for RP1 in combination with nivolumab for the treatment of advanced melanoma, based on the safety and clinical activity observed in the anti-PD-1 failed melanoma cohort of the IGNYTE clinical trial.

The confirmatory IGNYTE-3 trial is assessing RP1 in combination with nivolumab in patients with advanced melanoma who have progressed on anti-PD-1 and anti-CTLA-4 therapies or are ineligible for anti-CTLA-4 treatment. For more information, please visit View Source

About Melanoma
Melanoma is the fifth most common cancer, with approximately 100,000 new cases and 8,000 deaths estimated in the U.S. in 2024.i Standard of care therapy includes treatment with immune checkpoint blockade, to which approximately half of patients will not respond or will progress after treatment. Options are limited after immune checkpoint blockade therapy, with no standard of care available to patients.

About RP1
RP1 (vusolimogene oderparepvec) is Replimune’s lead product candidate and is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP R-) and GM-CSF, intended to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response.

Colorectal cancer affects two million people worldwide annually and is the third most common cancer type. For patients with metastatic disease, survival prospects are limited, underscoring the need for new, effective treatments. Neogap’s immunotherapy, pTTL (personalised Tumour Trained Lymphocytes), is being developed to address these challenges by offering a personalised treatment based on the patient’s own immune cells.

The clinical trial is being conducted in Sweden at Karolinska University Hospital and Danderyd’s Hospital in Stockholm, as well as Västmanland Hospital in Västerås. The trial targets patients with stage IV metastatic colorectal cancer. Patients are being continuously recruited nationwide, and a total of 12–16 patients will receive the treatment. The primary aim is to evaluate safety and tolerability while collecting data on treatment response.

"We are delighted to have treated the first patients – this is a significant milestone in our clinical trial and our mission to develop curative treatments for critically ill cancer patients. We have an outstanding trial team and look forward to the upcoming results," says Samuel Svensson, CEO of Neogap Therapeutics.

About Neogap’s immunotherapy, pTTL
pTTL (personalised Tumour Trained Lymphocytes) is a cell-based immunotherapy that enhances the patient’s own T cells to fight cancer. The therapy combines sophisticated DNA sequencing with T-cell expansion to deliver a precision treatment for solid tumours. It is powered by Neogap’s patented technologies, PIOR and EpiTCer. The goal is to provide patients with a tailored and innovative therapy that meets their specific needs.

The clinical trial is conducted in collaboration with the following units:

Phase 1 unit, Center for Clinical Cancer Studies, Theme Cancer, Karolinska University Hospital Solna, Stockholm, Sweden
Medical Unit Cell therapy and Allogeneic stem cell transplantation (ME CAST), Theme Cancer, Karolinska University Hospital Huddinge, Stockholm, Sweden
Medical Unit Pelvic cancer – Colorectal cancer, Theme Cancer, Karolinska University Hospital Solna, Stockholm, Sweden
Department of Surgery, Västmanlands Hospital, Västerås, Sweden
Department of Surgery and Urology, Danderyd’s Hospital, Stockholm, Sweden
