Any drugs / clinical trials for KRAS mutation?

My mom who is now stage IV NSCLC adenocarcinoma with mets in bone, brain and liver is just told that she has the KRAS mutation. But her doctor said there is no drugs and no clinical trials going on for this mutation.

Does anyone have any knowledge about this? Or can point me to any website that may contain this information? Thanks so much in advance.

I am sure CraiginPa will have much more information for you but I would give Dr. Alice Shaw at Mass General in Boston a call.

Report post I just put in K-RAS and lung cancer and came up with several. You have to review the eligibilty and location to see if she's eligible. There are several completed, so skip over those. Is she on any treatment now? Take care, Judy

I'm in almost the exact situation - my mom has stage IV NSCLC adenocarcinoma with mets in brain and liver (no bone, yet) and is also KRAS positive. Once we found out she has the KRAS mutation, i did a lot of research and found that there are no specific targeted therapies, but there are a lot of investigational drugs that appear promising for KRAS patients.

Here's a discussion on an archived CancerGRACE forum from earlier this year that discusses many of the options: If you haven't been on CancerGrace yet, i HIGHLY recommend it! This patient community for NSCLC has been a tremendous resource

And, to specifically answer your question, below are some of the drugs that researchers are looking at to treat NSCLC with KRAS:

Tivantinib (ARQ 197)
•c-Met Inhibitor

Ganetespib (STA-9090)
•Hsp90 Inhibitor

Retaspimycin HCl (IPI-504)
•Hsp90 Inhibitor

Selumetinib (AZD6244) - isn't looking as promising as others
•c-Met Inhibitor

Nexavar (sorafenib) - isn't looking as promising as others

GSK1120212 (JTP-74057)
•MEK Inhibitor

Seach for trials with these drugs. I'd also possible check out the FDA’s Emergency Use Investigational New Drug Program for Oncology Drugs: Approved/ApprovalApplications/InvestigationalNewDrugINDApplication/ucm10743 4.htm

Hope this helps and I relate to the situation you are in!

I was just at City Of Hope in Duarte last week and they have a trial going on for's the AZD6244 alone or in combination with Tarceva. Good Luck

Thank you all so much for your helpful insights!!

@MomFightsNSCLC - what a treasure trove of information you provided. This is exactly what i am looking for. Will look into each drug more in depth but this is a terrific starting point.

@Judy - thank you for the link. I looked at the sight and have contacted KRAS clinic trials for information. Very helpful.

I think you've already been given very good answers and I can't add much, but . . .

FWIW, here's my list of "potential" (not necessarily promising) drugs or combos for KRAS that I've heard mentioned in news or research, although I haven't specifically been researching for KRAS so this isn't complete or necessarily the best list.

The most interesting one, claiming a 60% success rate among the small number KRAS patients in their early-phase trial, is ganetespib, as you can read at:
However, that's a 'marketing' release, so consider it skeptically. (There are probably better HSP90 inhibitors out there who haven't said so, and HSP90 inhibitors might be a bit overzealous and not selective enough to avoid reaching toxicity before effectiveness.) Still, 60% even in a small group of KRAS patients is better than anything else I've heard of for KRAS. (ganetesipib) (ganetespib + docetaxel)
FWIW, the above has been discussed briefly on both cancergrace.organd

And below is a laundry list of other drugs and combos that I tabulated are being explored either in the lab or in trials. I don't know if any look "promising" yet and most will not have reached clinicial trials yet, but you could google for current details:

Hi Guys

I was reviewing the ESMO LC conference "poster" videos - and one of the doctors mentions some promising developments re combining HSP90 + mTor inhibitors - just wondered if any one had found/seen the actual study anywhere?



Report post

Duh - sorry Craig - as usual you gave the info I needed just to dumb to see it first reading

Report post

I have exact same diagnosis, but have had excellent response from Alimta/Gemzar Chemo combo.

(Tumors reduced by 30-50% after first 2 months.) Feel fine, no weight or hair loss.

Have had to learn to manage side effects, but definitely worth it!

A new experimental treatment that might be hopeful, though not yet in clinical trials, is this: ch-velcade-bortezomib-or-fasudil-via-gata2/

Best hopes,
