New York, NY, April 04, 2024 (GLOBE NEWSWIRE) -- Lirum Therapeutics, Inc. (Lirum), an innovative clinical-stage biopharmaceutical company focused on the treatment of debilitating diseases, announced today the upcoming presentation of positive data on LX-101, a novel clinical-stage targeted therapy directed to the insulin-like growth factor 1 receptor (IGF-1R), at the 2024 American Association for Cancer Research (AACR) Annual Meeting being held from April 5-10 in San Diego, California. Lirum’s data covers clinically-tested LX-101’s potent preclinical anti-tumor activity against variety of adult and pediatric cancers, including cancers of the head and neck and breast as well as certain sarcomas and neuroblastoma, all of which have well-established IGF-1R pathway involvement. In particular, these malignancies have known genetic alterations affecting the IGF-1R pathway and/or high IGF-1R expression tied to poor outcomes. The poster (abstract 1918) will be presented on Monday April 8th from 9:00am to 12:30pm PT in Section 23 of the poster hall and will also be available on the Lirum website (www.lirumtx.com) at the time of its presentation under the Investors and Media tab. Given these promising results and the existing clinical data, Lirum is planning new clinical trials with LX-101 focused on oncologic indications, both pediatric and adult, that carry well-established ties to the IGF-1/IGF-1R pathway. Lirum is also developing LX-101 in certain autoimmune diseases, including thyroid dye disease, where IGF-1R has been clinically and commercially validated. About Lirum Therapeutics, Inc.Lirum is an innovative clinical-stage biopharmaceutical company focused on the treatment of debilitating diseases through the acquisition, development and commercialization of novel drug candidates with compelling mechanisms of action, regulatory pathways and commercial opportunities. Lirum’s lead candidate, LX-101, is a novel clinical-stage targeted therapy directed to the insulin-like growth factor-1 receptor (IGF-1R) with a differentiated mechanism of action. Lirum is developing LX-101 in oncology and autoimmune indications, including thyroid eye disease (TED). For more information on Lirum, please visit www.lirumtx.com.

Actual results and outcomes may differ materially from those indicated in the forward-looking statements. Important factors that could cause actual results and outcomes to differ materially from those indicated in the forward-looking statements include, among others: our ability to successfully develop our product candidates, including obtaining positive results from planned clinical trials; expectations for the clinical development, manufacturing, regulatory approval and commercialization of our product candidates or other products we may acquire or in-license; expectations for incurring capital expenditures and generating revenue; estimates of the sufficiency of our existing cash and cash equivalents and investments to finance operations; changes in applicable laws or regulations; the possibility that we may be adversely affected by other economic, business, and/or competitive factors; the impact of health epidemics, including the COVID-19 pandemic, on our business and the actions we may take in response thereto; and other risks and uncertainties indicated from time to time. Although we believe that the plans and expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our plans and expectations will be attained, and therefore actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements.

Pictured: Blood sample for insulin-like growth factor-1 (IGF-1)/iStock, Jarun011 Crinetics Pharmaceuticals has secured another late-stage win as its oral, once-daily investigational drug paltusotine aced a second Phase III study for acromegaly, a rare hormonal disorder. The biotech’s stock shot up over 10% Tuesday morning following the announcement. In the late-stage trial, 56% of patients taking paltusotine achieved the primary endpoint for the insulin-like growth factor 1 (IGF-1) level compared to 5% on placebo. The treatment also helped reduce symptoms of the disease—a secondary endpoint of the study. No serious adverse events were reported. Acromegaly, sometimes referred to as gigantism, is a serious hormonal disorder caused by a benign tumor in the pituitary gland that secretes growth hormone. Over 25,000 patients in the U.S. suffer from the rare disease, which results in enlargement of face, hands and feet. Left untreated, it can cause type 2 diabetes, hypertension, heart disease and other serious complications. Surgical removal of the tumor is the preferred treatment but many patients are not candidates for surgery. Current pharmacological options include painful monthly injections or Pfizer’s subcutaneous daily injection of Somavert. The Phase III data are the second positive trial results for Crinetics in acromegaly. In September 2023, the biotech shared data for a study of paltusotine in patients who switched from their current injections to Crinetics’ pill. Among treated patients, 83% were able to maintain their IGF-1 levels within the upper limit of normal, compared to only 4% of those on placebo. With these data in hand, Crinetics plans to submit its New Drug Application to the FDA in the second half of this year, while prepping for a 2025 launch. Jefferies analysts believe the market opportunity could be around $300 million for the company. Crinetics is also testing the drug candidate in carcinoid syndrome, reporting positive Phase II topline results last week. Kate Goodwin is a freelance life science writer based in Des Moines, Iowa.
