Shares of immuno-oncology concern Janux Therapeutics, Inc. (NASDAQ:JANX) rebounded considerably off their all-time low set in November 2023 on no operational information. Buyers might need been anticipating good information, as after the corporate posted trial outcomes after the bell on Monday, that precipitated the shares to greater than triple in early buying and selling on Tuesday. One other “inform” might need been important insider shopping for within the inventory in November.
That mentioned, they had been buying and selling at a major low cost to money after falling 85% peak-to-trough, as the corporate has solely produced medical knowledge from eight sufferers in 30 months since going public. We check out the brand new trial outcomes and supply an evaluation round Janux Therapeutics under.
Looking for Alpha
Firm Overview:
Janux Therapeutics, Inc. is a San Diego-based early clinical-stage biopharmaceutical concern targeted on the event of tumor-activated immunotherapeutics for the therapy of most cancers. The corporate options two distinct fabrication platforms, one among which has spawned two medical applications. Janux was shaped in 2017 and went public in 2021, elevating web proceeds of $204.2 million at $17 per share. The inventory has soared to almost $47.00 a share (at time of article submission), translating to an approximate market cap of $2 billion.
Improvement Platforms
The corporate has created two bispecific improvement platforms, every with an goal of manufacturing therapies that provoke a affected person’s personal immune system into eradicating tumors with minimal off-site antagonistic results.
November Firm Presentation
The output of its Tumor Activated T Cell Engagers (TRACTr) and Tumor Activated Immunomodulators (TRACIr) know-how platforms function the next: an antigen-binding area and a T cell-binding area (collectively, T cell engagers (TCEs); domain-optimized peptide masks; an albumin-binding area; and cleavable peptide linkers. Within the case of TRACTr, the bispecific consists of a CD3 T cell binding area, and within the case of TRACIr, the TCE is characterised by a CD28 binding area. The masks block binding (and thus exercise by the TCEs) till they’re eliminated by tumor proteases. The albumin-binding area is designed to increase the half-life of the TCEs. This strategy will not be new, however first-generation TCEs have been suffering from cytokine launch syndrome [CRS] and on-target wholesome tissue toxicities which have compelled the termination of many medical applications.
Moreover, authorised TCEs comparable to Amgen’s (AMGN) Blincyto (blinatumomab) are characterised by quick half-lives and, as such, therapy protocols include steady low-dose, multi-week infusions, which create a major affected person burden.
By the masks, Janux goals to scale back on-target and wholesome tissue toxicity points. As said beforehand, the albumin-binding area is designed to enhance the half-life of the TCEs to advertise once-weekly dosing. Moreover, within the preclinic, Janux’s TCEs solely wanted low ranges of tumor goal expression to set off T cell activation. Though a considerably novel strategy to TCEs, TRACTr and TRACIr manufacturing carefully resembles manufacturing modalities for monoclonal antibodies, which ought to preserve their price of products comparatively low.
Pipeline
The corporate’s TRACTr platform has produced two medical applications: JANX007 and JANX008.
November Firm Presentation
JANX007 is designed to disable PSMA, a protein that’s expressed in prostate most cancers tumors and within the blood vessels of different tumors. Steady dosing of infused PSMA-TCE has produced medical advantages, however given the present administration and security profile shortcomings of those choices, there’s appreciable room for enchancment for treating the second most prevalent most cancers amongst American males, which is predicted to take the lives of greater than 34,000 in 2023. JANX007 is present process Part 1 analysis and early interim returns had proven some promise and yesterday’s knowledge confirmed that optimism.
In July 2023, Janux launched knowledge on eight sufferers overlaying three dose cohorts. JANX007 demonstrated medical exercise at each the 100µg and 300µg flat doses with PSA reductions between 31% and 67% in 4 of 5 sufferers. Grade 1 and a pair of CRS occasions (fever, hypotension, and hypoxia) had been noticed in all seven sufferers with PSA discount and never within the sole non-responder, suggestive of on-site exercise. Additional buttressing this sentiment was the truth that PMSA was not present in topics’ wholesome tissues. Though a small subset of sufferers, these outcomes in contrast favorably versus different medical applications. The market didn’t reply meaningfully to this information as optimism was offset by a secondary providing. The trial continues to enroll sufferers, with one other replace scheduled someday in 2024.
Although JANX007 is off to a good begin, there are not any fewer than 13 different therapeutic candidates, together with choices from heavyweights Amgen, AbbVie (ABBV), Johnson & Johnson (JNJ), Gilead (GILD), and Novartis (NVS) (amongst others), within the clinic chasing the prostate most cancers indication.
Janux’s different medical program is JANX008, a TRACTr candidate that targets epidermal development issue receptor (EGFR) for the therapy of a number of stable tumors, together with colorectal [CRC], non-small lung, renal cell, and squamous cell carcinoma of the top and neck (SCCHN).
EGFR is a validated goal with authorised monoclonal antibodies together with Eli Lilly’s (LLY) Erbitux (cetuximab) and Cyramza (ramucirumab), in addition to Amgen’s Vectibix (panitumumab) for the therapy of CRC and SCCHN. Moreover, Amgen, Merus (MRUS), Regeneron (REGN), Roche (OTCQX:RHHBY), and Takeda (TAK) are pursuing EGFR within the clinic.
As for its TRACIr applications, the corporate is advancing JANX009, a programmed death-ligand 1 or PD-L1-TRACIr for the therapy of stable tumors. An IND has been submitted and as soon as within the clinic, it’ll face co-stimulatory multi-specific competitors from Regeneron, Sanofi (SNY), and Xencor (XNCR).
Merck Collaboration
Earlier than Janux went public, it inked a take care of Merck (MRK) underneath which it licensed its know-how on TRACTr immunotherapies for 2 targets. Collectively, Janux acquired $16 million upfront and is eligible to gather improvement and regulatory milestones as much as $285 million, business milestones as much as $700 million, and low single-digit to low-teens royalties. One undisclosed goal was chosen in December 2020 and the opposite in Could 2022.
Share Value Efficiency
With some validation to its strategy from the Merck collaboration in its hip pocket, Janux was a hotly wanted deal, with its inventory’s first commerce executed at double its IPO value, peaking at $37.99 per share later in its opening session. That print would show to be its all-time excessive, as is often the case when a biotech produces interim medical knowledge from solely eight sufferers over the course of its first 30 months as a publicly traded concern. Shares of JANX hit an intraday all-time low of $5.65 on November 10, 2023 earlier than their current huge transfer.
Trial Information:
This big rally was triggered by trial knowledge that was disclosed after the bell yesterday. Janux disclosed encouraging and up to date knowledge for each JANX007 and JANX008. Particularly, round JANX007 outcomes:
- 83% (5/6) of topics achieved PSA50 declines with first step dose ≥ 0.2mg
- 56% (10/18) of topics achieved PSA50 declines with first dose ≥ 0.1mg
- No CRS larger than Grade 2 was noticed in any cohort.
Stability Sheet & Analyst Commentary:
To fund its operations, the corporate held unrestricted money and investments of $349.7 million (~$7.50 a share) towards no debt as of September 30, 2023, aided by a July 2023 secondary of inventory and pre-funded warrants that raised web proceeds of $56.5 million at $12.46 per share subsequent to the JANX007 knowledge launch. Janux’s money runway extends to YE27.
With stable, albeit restricted knowledge, Avenue analysts are unanimously bullish on Janux’s prospects previous to this Monday’s information. H.C. Wainwright ($35 value goal), TD Cowen, Financial institution of America ($24 value goal) and Wedbush ($25 value goal) all have present Purchase rankings on the inventory. I might anticipate many Purchase reissuances and upward value goal revisions within the coming days primarily based on trial knowledge. As well as, with right now’s rally, the inventory is way above earlier value targets.
Useful proprietor Avalon Bio Ventures, represented on the board by Jay Lichter, took benefit of the inventory’s important low cost to money and bought 849,854 shares at $5.87 on November 13, 2023, upping its possession curiosity above 21%.
Verdict:
I want I might have had some JANX in my portfolio previous to yesterday’s trial information, clearly. Nevertheless, I might not chase this big rally. Buyers ought to needless to say, whereas the info was spectacular, it was Part 1 dose escalation knowledge and concerned a small subset of people. Extra knowledge from this examine will come out within the second half of this 12 months.
As well as, there’s huge competitors within the prostate most cancers house. For example, J&J by itself presently has seven medical applications (of 94) pursuing prostate most cancers. Whereas Janux has loads of money available, I might not be shocked if the corporate used the large rally within the shares to boost further funds, which might be dilutive. As well as, some 13% of the excellent float was held quick as of the top of January. A few of right now’s buying and selling motion may very well be pushed by a “quick squeeze.” Due to this fact, I’m not giving in to FOMO round JANX and can monitor this story because it develops.
