Patients receive erlotinib hydrochloride as patients in Arm A and cabozantinib-s-malate as patients in Arm B. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
So maybe you have a pair of variants, one probably responsive to Tarceva and one probably unaffected by Tarceva? If that is the situation and these are in different cancer cells, then maybe Tarceva could suppress some of the cells but not the other. I’m not sure if it’s possible for both to be present together in the same cells, but if so then I wonder if maybe the drug wouldn’t stop any cells (though maybe it could slow them a little). Your scans might have indicated whether there were any specific areas of benefit during that month.
The following side effects are common (occurring in greater than 30%) for patients taking Erlotinib:
Erlonat 100mg tablets are prescribed to patients for the treatment of metastatic Non-small cell lung cancer (NSCLC) that has spread to the surrounding tissues or other parts of the body. It is also used to treat certain types of pancreatic cancer in combination with another medicine gemcitabine.

Female BALB/c nude mice were implanted with the human NSCLC cell line SPC-A-1. The animals were given via gavage a single dose of erlotinib (4, 12.5, or 50 mg/kg). Pharmacokinetics of erlotinib was determined using LC-MS/MS. Tumor volume and pEGFR levels in tumor tissues were measured at different time points after erlotinib administration. The levels of pEGFR in tumor tissues was detected using Western blotting and ELISA assays.

To evaluate the efficacy and toxicity of erlotinib in patients with non-small cell lung cancer.
Five studies used EGFR inhibitors (gefitinib or erlotinib; n = 330) and 10 used a single chemotherapeutic agent (paclitaxel, docetaxel, gemcitabine or vinorelbine; n = 1,095). The authors note that none involved a direct head-to-head comparison of the two drug classes.
Adverse reactions occurring more frequently (≥3%) in Tarceva-treated patients than in the placebo group in the pivotal study BR.21, and in at least 10% of patients in the Tarceva group, are summarised by National Cancer Institute-Common Toxicity Criteria (NCI-CTC) Grade in Table 1.

The usual prescribed adult dosage of Erlotinib for Pancreatic Cancer is 100 mg orally per day.
13. A process for the preparation of a novel crystalline Form-M, having the above mentioned characteristics, as claimed in claims 1 to 2, of Erlotinib Hydrochloride of Formula-I, substantially as herein described with reference to Example- 1.
When initiating erlotinib therapy it is important to explain to the patient that skin disorders often develop during treatment and that if they experience any skin abnormalities, including on the scalp or around the nails, they should seek prompt medical attention. Preventive skin care may reduce the incidence, and prolong time to onset, of above grade 2 skin disorders and may also reduce severe skin toxicity. This theory is supported by data from the phase II STEPP trial in patients with metastatic colorectal cancer, as described earlier. 21

The LUX-Lung 8 trial randomized 795 patients with stage IIIB/IV SCC who progressed after first-line platinum doublet therapy; 398 patients received afatinib 40 mg/day and 397 received erlotinib 150 mg/day. The trial was stratified by east-Asian vs non-east-Asian patients, to mitigate any imbalance in treatment effect, Soria said.
La eficacia y la seguridad de TARCEVA en asociación con gemcitabina como tratamiento de primera línea se evaluó en un estudio aleatorizado, de doble ciego y controlado con placebo en 569 pacientes con carcinoma pancreático localmente avanzado, irresecable o metastásico. Se aleatorizó 1:1 a los pacientes para recibir TARCEVA (100 mg o 150 mg) o placebo una vez al día en una pauta continua junto con gemcitabina i.v. (1.000 mg/m2, ciclo 1: días 1, 8, 15, 22, 29, 36 y 43 de un ciclo de 8 semanas; ciclo 2 y ciclos siguientes: días 1, 8 y 15 de un ciclo de 4 semanas [dosis y pauta aprobadas para el carcinoma pancreático: véase el resumen de características del producto de la gemcitabina]). TARCEVA y placebo se tomaron por vía oral, una vez al día, hasta la progresión de la enfermedad o una toxicidad inaceptable. Las variables de valoración del estudio eran la supervivencia global, la tasa de respuesta y la supervivencia sin progresión. También se examinó la duración de la respuesta. La variable principal de valoración fue la supervivencia. Se aleatorizó a un total de 285 pacientes para recibir gemcitabina + TARCEVA (261 pacientes en el grupo de 100 mg y 24 pacientes en el de 150 mg) y a 284 pacientes para recibir gemcitabina + placebo (260 pacientes en el grupo de 100 mg y 24 pacientes en el de 150 mg). En el grupo de 150 mg fueron demasiado pocas las observaciones para extraer conclusiones.
We administered 150 mg erlotinib daily to three patients with NSCLC and CRF undergoing HD (HD group) and five patients with NSCLC and normal organ function (control group) and analyzed the PK of erlotinib and OSI-420. In the HD group, PK analyses were performed on day 1 (off HD), day 8 (off HD), and day 9 (on HD) after starting administration of erlotinib, and in the control group, they were performed on day 1 and day 8.

Table 4 summarizes the statistical comparison of the geometric mean ratios (300 mg/150 mg) for maximum plasma concentration (C max ), C 24 . and area under the plasma concentration-time curve during the dosing interval (AUC 0-tau ) of erlotinib and OSI-420. The data demonstrate a significant difference in exposure between the 150-mg and 300-mg cohorts. The percent geometric mean ratios (300 mg/150 mg) for dose-normalized C max and AUC 0-tau of erlotinib were 93.4 (90% CI, 66.4 to 131; P = .7355) and 113 (90% CI, 76.4 to 166; P = .6042), respectively. These results demonstrate erlotinib exposure was dose-proportional within the dose range tested.
Even more importantly, in order to obtain meaningful clinical responses it is crucial to effectively target the population of cells that are able to escape treatment and maintain the growth of a resistant tumor. 21 Cancer stem cells (CSCs) have been in fact identified within most solid tumors, including lung tumors, and are associated with increased resistance to therapies. 22. 23. 24. 25. 26. 27. 28. 29. 30 Thus, the efficacy of innovative therapeutic strategies should be validated against these more aggressive, tumor-maintaining cells. 23. 27. 31 Importantly, TKI response has never been determined at the level of the tumor-maintaining CSCs. Thus, we investigated erlotinib response of EGFR mutation-negative lung cancer stem cells (LCSCs) and LCSC-based xenografts with the attempt to evaluate their sensitivity to the drug and correlate it with their molecular pattern in order to identify potential biomarkers predictive of erlotinib response in a WT-EGFR context at the CSC level.
