Head and neck most cancers might be handled with a number of drugs available on the market, however for sure sufferers identified with this widespread sort of most cancers, outcomes are poorer and higher therapeutic choices are wanted. Bicara Therapeutics is creating a remedy that would present an alternate remedy, and the corporate has now raised $315 million in IPO cash to fund a pivotal research.

Boston-based Bicara was in a position to increase greater than deliberate. In preliminary IPO phrases set Monday, the corporate deliberate to supply 11.7 million shares priced between $16 and $18 every. On Wednesday, Bicara elevated the proposed share sale to 14.7 million shares supplied on the similar goal value vary. When the shares have been lastly priced Thursday evening, Bicara elevated the deal measurement once more, providing 17.5 million shares at $18 every, simply above the goal value vary. These shares now commerce on the Nasdaq underneath the inventory image “BCAX.”

Most circumstances of head and neck squamous cell carcinoma (HNSCC) come up from publicity to cancer-causing brokers reminiscent of tobacco smoke or human papillomavirus (HPV), Bicara stated in its IPO submitting. That virus can result in mobile modifications that turn into precancerous after which cancerous over time. Nevertheless, an estimated 80 % of recurrent or metastatic HNSCC circumstances are HPV-negative. These tumors are related to an elevated danger of deadly tumor bleeding, excruciating ache and swallowing difficulties.

Bicara’s medicines are antibodies designed to assault stable tumors by hitting two validated most cancers targets. The corporate’s lead program, ficerafusp alfa, is a bifunctional antibody drugs designed to bind to epidermal development issue receptor (EGFR) and human reworking development issue beta (TGF-beta).

TGF-beta is a key goal as a result of excessive signaling of this protein is related to resistance to a category of immunotherapies known as checkpoint inhibitors. For that reason, medicine that focus on this protein have been examined as a solution to doubtlessly overcome this resistance. GSK and Merck KGaA tried this method with a bifunctional protein, bintrafusp alfa. However medical trial outcomes confirmed that the experimental remedy fell quick by way of efficacy. In its IPO submitting, Bicara stated such failures might be as a consequence of inadequate antitumor exercise, probably as a result of the immunotherapy is expressed in immune tissue relatively than within the tumor microenvironment (TME) the place it’s wanted.

Bicara says its drug’s twin method blocks survival signaling EGFR and immunosuppressive TGF-beta signaling within the TME. Bicara is testing its investigational drug together with Merck’s blockbuster immunotherapy pembrolizumab, model identify Keytruda, whose permitted indications embrace HNSCC. An ongoing Section 1/1b trial of Bicara’s drug is involving a gaggle of HNSCC sufferers who had not but acquired remedy after their most cancers had superior. In that cohort, Bicara stated, the mixture of the investigational drug and Keytruda led to an total response fee of 54% in sufferers evaluable for efficacy. In sufferers with HPV-negative illness, the general response fee was 64%. For context, the historic response fee in a Section 3 trial of Keytruda monotherapy in HNSCC was 19%, the corporate stated within the submitting. The corporate expects to report extra Section 1/1b information at a medical assembly in 2025.

“Primarily based on the medical information generated so far, we consider that ficerafusp alfa together with pembrolizumab has the potential to turn into an ordinary of care first-line remedy in HPV-negative [recurrent/metastatic] “HNSCC,” Bicara stated within the submitting. “We additionally consider that ficerafusp alfa has the potential to offer significant medical profit in different stable tumors the place there’s a robust organic rationale for twin inhibition of each EGFR and TGF-beta, reminiscent of colorectal most cancers and different squamous cell carcinomas that sometimes overexpress EGFR and TGF-beta pathways.”

A pivotal Section 2/3 medical trial is deliberate that may check the Bicara remedy together with Merck’s immunotherapy pembrolizumab, model identify Keytruda, as a first-line remedy for superior HNSCC. Bicara expects this trial to begin late this yr or within the first quarter of 2025.

Bicara was based in 2018. The next yr, the corporate licensed sure fusion proteins from Biocon Restricted. Essentially the most superior of these fusion proteins was ficerasfusp alfa. There aren’t any future milestone funds or royalties related to the deal, Bicara stated within the submitting. The prospectus says Bicara has raised $353.1 million since its founding. The latest funding was a $165 million Collection C spherical introduced in December of final yr. Biocon is Bicara's largest shareholder, proudly owning an 11.28% stake post-IPO, in response to the submitting. RA Capital Administration will personal a ten.5% stake post-IPO.

On the finish of the second quarter of this yr, Bicara reported a money place of $203.9 million. Mixed with the proceeds from the IPO, the corporate plans to spend roughly $265 million on the event of ficerafusp alfa in HNSCC, together with the pivotal research and the submission of a biologics license software. One other $30 million is reserved for increasing its lead drug candidate into further HNSCC affected person populations. And $25 million is reserved for advancing the drug’s medical growth in further stable tumor sorts, reminiscent of colorectal most cancers and different squamous cell carcinomas.

Zenas IPO Raises $225 Million for Pipeline Product Alternative in I&I

Zenas Biopharma, an organization creating antibody medicine to deal with immunology and irritation (I&I) issues, raised $225 million. The corporate priced greater than 13.23 million shares at $17 every on Thursday evening. When Zenas set preliminary monetary phrases this week, it deliberate to supply 11.76 million shares within the vary of $16 to $18 every, which might have raised $199.9 million on the midpoint. Zenas shares commerce on the Nasdaq underneath the image “ZBIO.”

Extreme exercise of B cells, a kind of immune cell, is related to numerous autoimmune ailments. Whereas there are at the moment antibody medicine obtainable that deal with these situations by depleting B cells, Zenas says they don’t absolutely goal B cells in related tissues and that the dosing schedule of those therapies might be improved. One other concern is that antibody medicine that focus on and block the CD19 and CD20 proteins on B cells can deplete these cells for six months or longer, growing the danger of an infection and doubtlessly decreasing a affected person’s skill to answer and profit from vaccines.

Zenas’ lead drug candidate is obexelimab, a bifunctional antibody designed to bind to CD19 and Fc gamma receptor IIb, each targets which can be extensively expressed on B cells. Based on Zenas, this method mimics a pure antigen-antibody advanced to inhibit B cells. This mechanism of motion is meant to inhibit the exercise of B cells with out utterly depleting them. Zenas acquired world rights to obexelimab from Xencor in 2021. The corporate beforehand in-licensed different packages from Xencor; these packages stay preclinical.

Whereas Zenas believes obexelimab has broad potential in I&I, the corporate is initially concentrating on 4 indications: immunoglobulin G4-related illness (IgG4-RD), a number of sclerosis, systemic lupus erythematosus and heat autoimmune hemolytic anemia (wAIHA). Zenas' drug is furthest superior in IgG4-RD, a persistent inflammatory situation that impacts a number of organs. Normal remedy contains corticosteroids. Roche's CD20-targeting antibody drug, Rituxan, can be used to deal with the situation. Zenas is pursuing a Section 3 trial of its lead drug in IgG4-RD.

Since its founding, Zenas stated it has raised $358.3 million from traders. The corporate's most up-to-date funding was a $200 million Collection C spherical in Could led by SR One. That investor owns a 7% post-IPO stake in Zenas, in response to the submitting. Xencor is Zenas' largest shareholder with an 8.1% post-IPO stake.

In late June, Zenas reported that it had $183.9 million in money. That capital, together with the proceeds from the IPO, will broadly assist the development of obexelimab. Zenas plans to spend about $100 million on medical growth of the drug, together with the completion of a Section 3 trial in sufferers with IgG4-RD. The drug candidate will even be evaluated in separate Section 2 trials in a number of sclerosis, lupus and wAIHA. The corporate expects the capital to final for the subsequent two years.

MBX Bio's Longer-Lasting Peptide Medication Raises $163M for Scientific Trials

MBX Biosciences' preliminary public providing raised $163 million for a pipeline of a lead program within the clinic for a uncommon hormone deficiency with few FDA-approved remedies. Carmel, Indiana-based MBX priced its providing of 10.2 million shares at $16 every, which was the excessive finish of the $14 to $16 per share value vary it had set earlier this week. The corporate was in a position to enhance the scale of the deal by providing 1.7 million extra shares than it had initially deliberate. MBX shares commerce on the Nasdaq underneath the image “MBX.”

MBX’s medicine come from a platform expertise that designs peptides with longer durations of motion, permitting for much less frequent dosing intervals. This expertise is predicated on analysis from Indiana College. Lead program MBX 2109 is a possible remedy for persistent hypoparathyroidism, a situation through which the parathyroid glands don’t produce sufficient parathyroid hormone to manage calcium and phosphate ranges within the blood.

The primary FDA-approved remedy for the situation was Takeda Pharmaceutical’s Natpara, an engineered model of the hormone. However Takeda has stated it is going to cease providing Natpara as a consequence of ongoing manufacturing issues. Sufferers have a brand new different after the FDA permitted final month of Ascendis Pharma’s Yorvipath, a once-daily peptide that helps carry parathyroid hormone ranges into the conventional vary.

With MBX 2109, MBX goals to supply sufferers with persistent hypoparathyroidism much less burdensome, once-weekly dosing. In Section 1 testing, the corporate reported that the engineered peptide achieved parathyroid hormone ranges similar to these achieved with a steady infusion. A Section 2 research dosed its first affected person final month; preliminary information is anticipated within the third quarter of subsequent yr.

One other engineered peptide, MBX 1416, is in Section 1 growth for post-bariatric hypoglycemia (PBH). This uncommon situation causes sufferers who bear bariatric surgical procedure to develop dangerously low blood sugar ranges. There aren’t any FDA-approved therapies for this uncommon situation, however MBX isn’t the one one pursuing it. Amylyx Prescribed drugs picked up its Section 3-ready PBH peptide drug from Eiger BioPharmaceuticals’ chapter public sale. One other engineered peptide, MBX 4291, is in preclinical growth for weight problems.
