The ELEVATE trial (NCT05563220) is an ongoing part 1b/2 examine investigating elacestrant (Oserdu) mixed with numerous focused therapies for sufferers with endocrine rececptor-positive (ER+)/HER2-negative (HER2–) metastatic breast most cancers (mBC) who’ve already acquired endocrine remedy and CDK4/6 inhibitors.
Endocrine remedy mixed with CDK4/6 inhibitors is the usual first-line remedy for ER+/HER2- mBC. Nonetheless, resistance to endocrine remedy finally develops, limiting remedy choices. Elacestrant, a brand new kind of drug, has proven promising leads to sufferers with acquired resistance on account of ESR1 mutations.
The ELEVATE trial is evaluating the protection and efficacy of elacestrant mixed with 4 totally different focused therapies: everolimus, alpelisib (Vijoice, Piqray), ribociclib (Kisqali), and palbociclib (Ibrance). The preliminary part goals to find out the most secure and handiest dose for every mixture.
The trial enrolled sufferers in cohorts for every elacestrant and focused remedy mixture. All combos had been well-tolerated with antagonistic results per the identified security profiles of the person medicine. The most typical unwanted effects included decreased neutrophils, nausea, fatigue, diarrhea, and rash. No sudden security considerations had been noticed.
These early findings recommend that elacestrant mixed with focused therapies could also be a promising remedy choice for sufferers with ER+/HER2– mBC who’ve grow to be resistant to plain therapies. The trial is ongoing, and additional knowledge on security, efficacy, and long-term outcomes might be reported.

0:05 | Effectively, the primary and now solely oral selective estrogen receptor down regulator with regulatory approval is elacestrant. Elacestrant within the EMERALD trial [NCT03778931] confirmed, notably in sufferers with endocrine-sensitive illness, improved progression-free survival in comparison with fulvestrant. And when that subset was checked out, some sufferers who had had earlier fulvestrant might have acquired exemestane. So this end result led to approval of elacestrant. However when the entire evaluation within the intent-to-treat inhabitants confirmed an enchancment, once they regarded on the affected person inhabitants with ESR1 mutations, enchancment seem like a lot larger. So the approval for elacestrant is within the ESR1-mutant inhabitants as in sufferers whose cancers progressed on aromatase inhibitors, and importantly in EMERALD, all sufferers needed to have acquired a CDK4/6 inhibitor. And this understanding of what to do in sufferers whose cancers have progressed on an aromatase and CDK4/6 inhibitor is essential. So that is what the present approval is for sufferers with ESR1 mutations.
1:07 | However then we go to the current day the place we actually do not need to give single-agent endocrine remedy even within the second-line setting. We’re actually fascinated with combos with focused brokers. So the ELEVATE trial is absolutely attempting to have a look at each, first the protection of mixing elacestrant with any variety of focused brokers, basically those that we’ve to make use of, after which within the part 2 growth, so that is the part 1b half, wanting on the efficacy of those combos, and naturally, further security with bigger numbers of sufferers. So we’re capable of now take a look at all of the CDK4/6 inhibitors. And we began out with alpelisib. However now we change gears to have a look at capivasertib [Truqap], the AKT inhibitor, as we actually count on that almost all sufferers might be handled with capivasertib have PIK3CA pathway alterations, reasonably than alpelisib on account of an improved security profile. The ELECTRA examine [NCT05386108] really has already proven in part 1b testing that the mix of elacestrant and alpelisib at full dose is protected and is transferring on to check that mixture in sufferers with mind metastases. However now we’ve the part 2 growth cohort in elevate wanting on the mixture, not in sufferers with mind metastases, with elacestrant, alpelisib, and abemaciclib [Verzenio]. In order that’s really a very nice mixture that is being evaluated now, within the part 2 growth.
2:32 | Actually, for ELEVATE, you need not have an ESR1 mutation. So it is actually all comers, which is able to increase our knowledge in sufferers who do not have ESR1 mutations, wanting on the oral agent elacestrant. We’re nonetheless ribociclib. And the part 1b portion, we all know that it is protected together with 400 milligrams, and we’re simply doing 1 further cohort was 600 milligrams. After which together with everolimus, we checked out 5 milligrams, after which 10 and seven.5. And we determined that it was best to present 7.5 milligrams, not as a result of there was any pharmacokinetic interplay, however as a result of simply sufferers tolerate 7.5 milligrams higher. So we’re now our growth examine with elacestrant and everolimus, which we’re actually enthusiastic about. So the combos of those brokers, I believe are is a extremely essential pathway ahead. It does meet an unmet want for our sufferers. And the ELEVATE trial is already transferring ahead with the dose growth in sure cohorts and ought to be increasing different cohorts later this yr. We’re very excited, we’ll be finding out capivasertib and elacestrant within the part 1b portion, after which we’ll increase to part 2 over time.
