The abstract reports the findings from an ongoing first-in-human study of LNP8701 in patients with solid tumors. LNP8701 is an orally administered, investigational SOS1 (Son of Sevenless1) inhibitor, designed to block SOS1-mediated RAS activation, thereby limiting oncogenic signaling that promotes tumor growth. Results indicate that LNP8701 was well tolerated with desirable safety, pharmacokinetics profile and favorable anti-tumor activity. The preliminary efficacy findings demonstrate that two patients completed LNP8701 monotherapy for 12 cycles (i.e., 1 year) and one patient completed 14 cycles with stable disease.

Vinita Gupta, CEO, Lupin, said, "The findings from the ongoing Phase 1 study highlight the emerging potential of LNP8701 and signal progress in our pursuit of novel therapies for difficult-to-treat cancers. We are encouraged by this momentum and remain committed to transforming scientific discovery into meaningful patient outcomes."

Current data suggest that LNP8701 is safe and well-tolerated across all tested dosing levels. Lupin will continue to study the efficacy of LNP8701 in its phase 1b trial in India and explore its potential to treat solid tumors both as a monotherapy and as part of a combination.

Summary

Results: 109 participants with advanced gastrointestinal cancer were evaluated in the study and all but one had prior chemotherapy in the advanced setting. 95% were previously treated with oxaliplatin (65%) or cisplatin (30%). 45 patients (41%) had prior neuropathy. On study, 24 patients (22%) experienced at least one oxaliplatin-induced peripheral neuropathy (OIPN) adverse event. Lower OIPN incidence was observed across all cohorts relative to benchmarks: mCRC (14% vs. 53%), BTC (32% vs. 68%), GC (19% vs. 63%), and pancreatic cancer (29% vs. 38%). Only 9 patients (8.2%) discontinued oxaliplatin, with only 2 attributed to OIPN. Of 69 dose reductions, 16 (23%) were due to OIPN. Patients at the highest BOLD-100 dose level (625 mg/m2) had the lowest OIPN incidence.

Conclusions: Analysis of safety and dosing data from this study suggests a potential neuroprotective effect of BOLD-100 against oxaliplatin-induced peripheral neuropathy.

Bold Therapeutics is currently advancing BOLD-100 through a global Phase 2 randomized controlled trial across sites in Canada, European Union, and South Korea. This trial is investigating BOLD-100’s anticancer efficacy, but also includes important quality of life questionnaires focused on its neuroprotective potential.

The ELEVATE study was designed to evaluate the safety and efficacy of combination treatment options with elacestrant, to overcome different resistance mechanisms observed in ER+/HER2- mBC and improve patient outcomes, irrespective of ESR1 mutation status. The study is composed of six treatment regimens evaluating elacestrant in combination with CDK4/6 inhibitors (palbociclib, abemaciclib and ribociclib) and with inhibitors of the PI3K/AKT/mTOR pathway (everolimus, alpelisib and capivasertib).

ELEVATE results reported at ASCO (Free ASCO Whitepaper) 2026 (abstract 1098)[1] include safety and preliminary efficacy data from the phase 1b elacestrant (258-345 mg) plus capivasertib (320-400 mg) cohorts (n=31), which demonstrate preliminary median progression-free survival (mPFS) benefit in the recommended phase 2 dose (RP2D) cohort. The RP2D was determined in cohort 2 (n=9) to be elacestrant 345 mg plus capivasertib 320 mg BID (4 days on/3 days off).

In RP2D response-evaluable patients, preliminary efficacy showed an 88.9% disease control rate (DCR), a 66.7% clinical benefit rate at 24 weeks (CBR24), and a 33.3% objective response rate (ORR). All patients with ORR had co-existing ESR1 and PIK3CA mutations. The median duration of response (mDOR) has not yet been reached. The preliminary mPFS was 11.3 months in the overall RP2D population, and 10.9 months in patients with co-existing ESR1 and PIK3CA mutations. Additionally, these initial results show that the combination is consistent with the known safety profiles of each targeted therapy plus standard of care endocrine therapy.

"The combination of elacestrant plus capivasertib is designed to address an unmet need for patients with ER+/HER2- PI3K-pathway altered metastatic breast cancer, particularly when co-existing ESR1 and PIK3CA mutations are present." said Sara Tolaney, MD, MPH, Chief of the Division of Breast Oncology, Dana-Farber Cancer Institute. "These encouraging preliminary data suggest the potential for extended clinical benefit with a manageable safety profile, as the combination regimen could simultaneously target ESR1 and PIK3CA mutations, potentially avoiding the need for sequential regimens that address each target individually."

"Building on the data we saw last year at SABCS, we continue to be encouraged by elacestrant’s potential clinical benefit observed across numerous combinations with different agents targeting ER+/HER2- metastatic breast cancer," said Elcin Barker Ergun, CEO of the Menarini Group. "The breadth of our studies, including early breast cancer and various combinations for ER+/HER2- metastatic breast cancer, including with capivasertib, demonstrate our commitment to bringing potentially transformational therapies to cancer patients."

In addition, other elacestrant data will be presented at the ASCO (Free ASCO Whitepaper) congress. See below for a complete list of upcoming presentations:
