Antineoplastons + Sotorasib
Sotorasib brand name: Lumakras.
We found no known interaction between Antineoplastons and Sotorasib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Antineoplastons and Sotorasib
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Sotorasib and Antineoplastons in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Antineoplastons at all — not against Sotorasib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Sotorasib Is Prescribed For, and What Antineoplastons Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Sotorasib is a prescription medicine with approved uses on its FDA label. Antineoplastons is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Sotorasib is prescribed for: Lumakras is used to treat adults with KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC) who have already received at least one prior cancer treatment. This use was approved under the FDA's accelerated approval pathway based on tumor response rates, and continued approval may depend on results from confirmatory trials. Lumakras is also used in combination with panitumumab to treat adults with KRAS G12C-mutated metastatic colorectal cancer (mCRC) who have previously received certain chemotherapy regimens. In both cases, patients must first be confirmed to carry the KRAS G12C mutation using an FDA-approved test.

Colorectal cancer studied, not established Antineoplastons has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Antineoplastons for colorectal cancer
Preliminary clinical research in adults who have undergone hepatectomy due to metastatic colorectal cancer shows that intravenous administration of antineoplastons A10 and AS2-1, in conjunction with hepatic arterial infusion of 5-fluorouracil, increases average cancer-specific survival from 39 months to 67 months, but does not reduce relapse-free survival, when compared with receiving 5-fluorouracil alone.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Sotorasib on your own; if you are taking Antineoplastons for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.
See Every Supplement That Interacts With Sotorasib
This page covers Antineoplastons only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sotorasib page lists 180 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Beer (major), Grapefruit (major), Siberian Cocklebur (major) and St. John's Wort (major).
By severity: 6 major · 137 moderate · 37 minor.
From our pharmacist’s overview on the Sotorasib page
“Grapefruit is the first thing I would drop while on sotorasib (Lumakras), a targeted lung cancer pill cleared by the CYP3A4 enzyme. Grapefruit blocks that enzyme and can push sotorasib levels up; St.”

Where Antineoplastons and Sotorasib Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.

#1,678 of 2,830 medications looked up here in the last 7 days
Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.

- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Antineoplastons reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Antineoplastons and Sotorasib records this page draws on were last updated July 10, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Antineoplastons
What is Antineoplastons?
- Cancer (various types, including brain tumors)
- Adjunct cancer support
- Investigational anticancer therapy
Antineoplastons are synthetic peptide and amino acid compounds promoted as an alternative cancer treatment, but they are not approved by the FDA and high-quality clinical evidence supporting their effectiveness is lacking. Most studies have been conducted by their developer and have not been independently confirmed. If you are considering them, talk with your oncologist first, and never replace proven cancer treatment with an unproven one.
Synthetic peptides, amino acid derivatives, and organic acids (originally isolated from human blood and urine) · Oral capsules and intravenous (IV) infusions, used mainly within specific clinics or research settings
An interaction check asks whether these two react with each other — it does not ask whether Antineoplastons is a good idea for someone in your situation. Here is what our Antineoplastons record says about it on its own.
Antineoplastons: dosing
There is no established, standardized safe dose of antineoplastons for any condition, and they are not available as a regular over-the-counter supplement. The doses studied have varied widely and were given under medical supervision, often as intravenous infusions.Because these products are unproven and can cause serious side effects, you should not try to dose them on your own. If you are considering antineoplastons, discuss it thoroughly with your oncologist and pharmacist first.
